Samsung develops blue QLED technology

Since abandoning the large-screen OLED technology route, Samsung has been increasing the research and development of QLED quantum dot technology, and most of its TV products also use QLED technology. At present, the advantage of QLED is that it can greatly increase the color gamut coverage of TVs and display more colors. However, the current QLED is far away from the “complete body” of electroluminescence.

Samsung develops blue QLED technology

The current QLED TVs on the market are still LCD TVs in essence, and the backlight is still an LED light source, but a layer of quantum dot film is added between the backlight and the liquid crystal to improve the color performance of the picture. The future of QLED is electroluminescent quantum dots. Like OLED, the pixels emit light, and there is no life-span problem of OLED organic light-emitting materials, and it will not burn the screen.

Although it is still far from the realization of electroluminescence technology, Samsung has never given up on exploration. Recently, Korean media reported that Samsung successfully developed blue QLED technology, which can increase the luminous efficiency of the screen by 20%, achieve a maximum brightness of 88,900 nits, and extend the QLED handle to 16,000 hours.

The so-called quantum dots are semiconductor particles with a diameter of nanometers. When illuminated, photoluminescent quantum dots emit light of different colors according to their size. Blue is the most difficult color among the three primary colors of QLED and has the largest band. The gap will be oxidized when exposed, which will shorten the service life and reduce the luminous efficiency.

Samsung said that the researchers used a double emission layer and a short ligand structure on the surface of the blue quantum dot, and increased the current injection rate to ensure the long-lasting light response of the quantum dot material. This technological innovation is expected to accelerate the implementation of electroluminescent quantum dot technology as soon as possible.

Fully LED street light in Gaoshi

Say goodbye to traditional lighting fixtures. The 240,000 street lights in Gaocheng will be fully LED, which is expected to be completed before the end of the year. The Gao City Public Works Bureau will also modify the “smart street light” system for 80,000 street lights in the urban area. Once the lights are damaged, they can be reported back through the Internet immediately, saving the maintenance department’s labor and cost for patrolling street lights at night.

Fully LED street light in Gaoshi

Since 2013, Gaoshi has gradually replaced high-pressure sodium gas lamps or metal-clad lamps. As of 2019, 120,000 LED street lamps have been replaced. Many of the lamps that have been out of warranty but have not been damaged have long been decayed. Fully updated together. At present, the overall refurbishment progress in the 35 districts of the city has reached 80%. Qianjin, Yancheng, Mi Tuo and Liugui districts have all been refurbished, and Renwu, Taishe, Tianliao, and Meinong districts have reached 90%. All replacements are expected to be installed by the end of the year.

The Bureau of Public Works stated that the subsidy from the Energy Bureau of the Ministry of Economic Affairs was limited before 2019, and only 120,000 LED street lights could be replaced in 7 years. Introducing private financing this year, and signing the “Energy-saving and Smart Street Lamp PFI (Private Finance Initiative, Private Finance Initiative)” replacement plan with two LED manufacturers. The manufacturer installs brand-new LED lamps and replaces the LEDs to save electricity costs. The manufacturer submits an application every six months. The Bureau of Works estimates that it takes about 8 years for manufacturers to pay back their costs.

The new LED street lamp consumes 70 watts of electricity per lamp, and the main roads such as Zhongshan Road use high-brightness 100 watt lamps. The Bureau of Public Works estimates that it can save about 108 million RMB in electricity bills, reduce power consumption by about 70 million kWh, and reduce carbon emissions by about 37,000 tons per year.

In addition, this year the Works Bureau also started to deploy “smart street lights” for street lights in urban areas. A black box for sensing is installed on the LEDs. Once damaged or unlit, it will be sent back to the system through the wifi generator to improve Rush repair efficiency.

The Bureau of Public Works emphasized that the illuminance and brightness of the new LED street lights meet the requirements. In response to some people’s dazzling response, engineers will adjust the angle of the street lights or install shading facilities to improve it.

2020 The global LED component market declines by 15%

Industrial Technology International Strategic Development Institute of Industrial Technology Research Institute recently released its latest estimate that the global LED component market may decline by 15% in 2020. Before March this year, the novel coronavirus pneumonia epidemic was mainly locked in mainland China. At that time, the hidden worries on the manufacturing side had gradually eased. However, after March, the epidemic in Europe and the United States caused the stagnation or decline of the LED demand-side market, which became the biggest cause of the LED component market decline. The epidemic can be effectively controlled in May, and the demand for LED components has a chance to return to the right track; once the epidemic drags into the second half of the year, the market estimate may have to be revised down again, because of unemployment pressure and consumption tightening, the recovery period may last more than 10 months.

2020 The global LED component market declines by 15%

Researcher Huang Mengjiao of the Institute of Industrial Technology International Strategy Development of the Industrial Technology Research Institute pointed out that the global LED components are expected to decline by more than 15% this year. Such a big recession has never been seen in the past, and the Eurozone market has suffered the most. If the new crown pneumonia epidemic is locked in the mainland, it is only a problem on the supply side, but the impact has all expanded to the market, and terminal LED demand has stagnated.

The main application markets for LED components are LCD TVs and portable products such as backlights, lighting, billboards, and automotive. The automotive market has fallen sharply in 2019, impacting the revenue of major LED component manufacturers; and most of the LED lighting is The commercial market is regularly updated and overhauled. Now, most areas of the world are restricting activities, and many commercial places are not even open for business. The lighting market has no prospects.

According to the latest forecast by Gartner, international research and consulting agency, in April this year, affected by the new crown pneumonia, LED backlight application markets such as NB, tablet computers, mobile phones, and LCD TVs have experienced a decline of about 5% to 15%. NB declined by more than 10%, and LCD TV declined by 15% the most. Huang Mengjiao pointed out that LCD TV was originally a saturated market, with shipments of 226 million units in 2019, which is expected to decline by 15% this year. The impact of the LED backlight application market is inevitable.

LED automotive lighting becomes a new kinetic energy

As the upstream industry of the automotive industry, automotive lighting periodically synchronizes with the automotive industry. Affected by the new crown pneumonia epidemic, the production and sales of China’s auto industry fell sharply in the first quarter, and the market began to pick up after entering the second quarter.

LED automotive lighting becomes a new kinetic energy

According to data released by the China Association of Automobile Manufacturers, in May this year, my country’s automobile production and sales both showed double-digit growth year-on-year. This is also the first time to achieve double-digit growth since the decline and rebound in April this year.

The car sales market is gradually recovering, which to a certain extent also drives the LED car lighting market to rebound. According to the forecast of the LED Research Institute of Advanced Industry Research (GGII), as LED automotive lighting begins to gradually penetrate into mid-range models, China’s LED automotive lighting market is expected to exceed 42.5 billion yuan in 2020.

It is precisely based on the obvious recovery of the automotive lighting market. At present, most manufacturers operating automotive lighting-related businesses have achieved steady growth or turned losses into profits. According to Gaogong LED’s observations, Everlight Electronics, Liqing, Seoul Semiconductor, Jinko Electronics, Hongli Zhihui, and other domestic and foreign companies have publicly expressed their optimism about the automotive lighting market.

According to Ye Yinfu, Chairman of Everlight Electronics, “Automotive LEDs will become a new niche market and act as a driving force for operational growth.” Seoul Semiconductor related personnel also pointed out, “In the future, we will further commit to the research and development of driving lights LED technology. ”

Hongli Zhihui has started to deploy the automotive market and automotive products as early as 2004. For many years, it has always been optimistic about the automotive lighting market prospects and established an automotive lighting division. In September 2019, it also signed a strategic cooperation agreement with European lighting brand TUNGSRAM in Budapest, Hungary, to jointly develop the global automotive lighting market.

In order to realize the vision of building a national brand of domestically-produced automotive LEDs, Hongli Zhihui established an automotive semiconductor technology branch in Guangzhou on July 1, 2020.

According to Liu Xinguo, head of the automotive lighting sector of Hongli Zhihui Group, “The localization trend of auto parts is becoming more and more obvious, and more and more independent brands will emerge. I believe that the automotive semiconductor technology branch has Opportunity to be a leading brand of domestic automotive lighting semiconductors.”

The global LED smart street lamp market will enter a stage of rapid development

Trend Force predicts in its latest survey that the global LED smart street lamp market (including only luminaires and a single lighting control system) will usher in rapid development and will grow at a compound annual growth rate of 8.2% by 2024.

Trend Force predicts in its latest survey that the global LED smart street lamp market (including only luminaires and a single lighting control system) will usher in rapid development, and will grow at a compound annual growth rate of 8.2% by 2024. LED lighting manufacturers, such as Signify, Acuity Brands, Zumtobel, Leotek (subsidiary of Lite-On Group) and Unilumin, have released new outdoor smart lighting products and integrated smart lighting solutions, which may improve smart LED The penetration rate of the street lights. However, Trend Force pointed out that downstream LED lighting demand is highly related to the overall economic situation. Analyst Christine Liu pointed out that governments around the world are trying to mitigate the impact of the COVID-19 pandemic on industries through fiscal policies, smart city construction, and new infrastructure investment. Among these government efforts, in terms of scale, China and North America have made the largest investment in roadside infrastructure. According to data from the US Census Bureau, as of June 2020, the US government has invested US$42.9 billion in roadside infrastructure. Efforts to stimulate the economy through government expenditures are expected to drive the demand for outdoor LED street lights. Driven by Huawei and Tencent, Chinese companies have become the main driving force for the development of smart street lights. Generally speaking, smart light poles have six basic functions: smart lighting, information release, security monitoring, environmental detection, charging stations and small 5G base stations. Smart lighting products ranging from modular LED lights to a single light controller are necessary components to achieve these six functions. Trend Force’s smart street light construction project cost analysis found that the average selling price (ASP) of the smartest street light pole with the highest specifications was US$6997.90, of which 2.6% came from smart lighting equipment, and the average selling price was US$182.5. Although China is the main driving force for the development of smart street lights in the world, large-scale city-level projects are expensive and time-consuming. This is mainly due to the huge land area in China and the huge differences in the needs of various local governments. In addition, the municipal government usually tends to outsource smart street lighting projects to private companies with sufficient resources. These companies are not necessarily proficient in the design and manufacturing of smart street lighting equipment, so they must cooperate with other partners to complete these projects. On the other hand, because smart street lighting projects involve the Internet of Things and telecommunications, LED lighting manufacturers must cooperate with major technology companies to execute these projects. Therefore, companies with strong resource integration capabilities, such as Huawei and Tencent, are expected to occupy a major share of smart street lighting projects in China. Trend Force believes that in the smart street light supply chain, if the downstream reach is wider, more and more business opportunities will be found. In order to enter the existing supply chain, LED lighting manufacturers must enhance their service system capabilities, streamline their LED lighting product portfolio and improve the overall service quality, to add more value to existing competitive advantages. At the same time, the government needs to formulate transparent standards for smart street lights and develop a comprehensive smart city blueprint to ensure the healthy development of the LED smart street light industry.

The scale of global smart light poles will increase by 7.97 billion!

According to a Technavio research report, the global smart pole market is expected to grow by USD 7.97 billion from 2020 to 2024.

The scale of global smart light poles will increase by 7.97 billion!

At present, my country’s smart light pole industry has also developed rapidly under the wave of new infrastructure. It is reported that as of June 2020, my country’s smart street light projects have won the bid for about 100, and the total project scale has reached 24.651 billion RMB.

Then, with the rapid development of the smart light pole industry, what will be the competitive landscape of my country’s smart light pole industry?

According to a research report by Founder Securities, there are currently no less than 400 or 500 companies under the name of “smart light poles”, and there are currently 61 companies that have truly implemented smart light pole projects or are under construction.

Among them, there are three major domestic operators, 4 telecommunications and Internet technology giants, 32 traditional lighting/communication-related companies (including the provision of finished smart light poles and others), and 22 cross-border manufacturers such as security, charging piles, and the Internet.

1, the three major domestic operators

The three major operators of China Mobile, China Unicom, and China Telecom have independently designed and built smart light poles or cooperated with manufacturers due to 5G network deployment requirements, occupying a place in the smart light pole industry.

In the 5G era, the construction of base stations is an important part of network deployment. Compared with 4G, 5G uses a high frequency and a high density of base stations. The construction of base stations in the 5G era faces problems such as difficulty in site selection, large investment, long construction period, and impact on the urban landscape. The smart street light pole is undoubtedly the best carrier for 5G base stations.

The three major domestic operators independently or in cooperation with Huawei and other manufacturers have deployed smart light pole construction. The 5G smart light pole and NB-IoT smart street light projects have been implemented.

2. Communications and Internet technology giants

Alibaba, Tencent, Huawei, ZTE, and other Internet and communication giants rely on technological advantages and platform resources to win multiple projects. They not only cooperate with other hardware manufacturers but also gradually have independently designed smart light poles.

Unisnug released UV disinfection lamp

Only in campus scenes, in the past two decades, the media has publicly recorded dozens of “campus ultraviolet lights hurting people”. Students’ eyes and skin were burned, all because of accidentally turning on or forgetting to turn off. Individual schools and kindergartens have loopholes in installation, management, and use, and people lack the understanding that ultraviolet rays can easily cause mass injuries. Unisnug recently released the intelligent control UV disinfection lamp, which can be turned on by remote control or front-end IPC linkage. It supports infrared human body induction. It stops working immediately when the human body is detected within 4.5 meters, which effectively eliminates human error and improves the safety and convenience of UV lamp use.

Unisnug released UV disinfection lamp

In life, viruses, bacteria, and molds that are invisible to the naked eye are everywhere. The current COVID-19 pandemic is spreading around the world, and public health incidents are frequent; kitchens and bathrooms in the home are humid, and the cabinets are prone to mold; the elderly and children have low immunity and are prone to seasonal allergies; pets in the house are more likely to be infected with parvovirus when they go out for a week; Pillows are covered with millions of mites…These hidden “killers” will come out to make trouble when the body’s resistance is low. The principle of ultraviolet sterilization uses UVC ultraviolet rays to destroy the DNA molecular structure of microbial cells, making them lose their ability to reproduce and self-replicate, and achieve the effect of sterilization and disinfection. The unisnug intelligent control ultraviolet disinfection lamp adopts wall-mounted installation, which effectively expands the scope of sterilization.

－Two-pronged approach for more sterilization: using the industry’s advanced deep-ultraviolet lamp sterilization technology, equipped with two ultraviolet lamps, combined with a structural optical reflective surface, improving light efficiency and ultraviolet sterilization ability, comprehensive disinfection and sterilization, purifying the air, and one-click on the whole house disinfection. There is a “smell of sunshine” in the air after disinfection;

－Remote control is more convenient: remote control, three-speed timing (30/60/120 minutes) off, delayed 15s to start, personnel can leave calmly; IPC (indoor camera) alarm output interface is connected to the disinfection lamp alarm input, that’s it Setting the UV lamp to turn on and off regularly is an integration and extension with Yushi’s main line products;

－Human body detection is safer: the human body infrared intelligent induction upgrade (dual PIR, any one can be triggered), that is, it will stop immediately when the human body is detected within 4.5 meters, and the delay will start again until the person leaves. It is effectively eliminated by technological means Human error and UV damage, comprehensively improve the safety of UV lamp use.

The intelligent control ultraviolet disinfection lamp illuminates a room of sunlight and starts a healthy life. It is suitable for homes, hotels, schools, kindergartens, hospitals and other scenes. Standardized use can be a weapon to cut off disease transmission. Unisnug takes safety as the core and provides intimate protection for consumers around a variety of life scenarios.

Precautions for use

1. When using UV disinfection lamps, people, animals and plants must leave the UV irradiation area.

2. Ultraviolet rays have certain damage to human skin and mucous membranes. Do not stare at the ultraviolet disinfection lamp for a long time. Take care to protect yourself.

3. When disinfecting items, spread or hang the items to expand the irradiation surface, the effective distance is one meter, and the irradiation is about 30 minutes.

4. Keep the environment clean during use. When the indoor temperature is less than 20°C or the relative humidity is more than 50%, the irradiation time should be extended.

5. After use, please ventilate first, and then enter the room after 30 minutes.

What scenarios are LED solar street lights suitable for?

In today’s increasingly energy-stricken world, only solar products have broken out. Compared with other energy sources, solar energy is a green resource, energy-saving and environmentally friendly, and is widely used in various scenes of daily life. As a member of the solar energy family, LED solar street lights are also favored by people. However, in practical applications, they will also be subject to many restrictions such as scenes.

What scenarios are LED solar street lights suitable for?

One, rural areas

Rural areas are very suitable for using LED solar street lights, because the natural environment in some rural areas is relatively harsh, which is not suitable for laying cables. Even if it can be laid, the overall cost may be higher than the solar street light itself, which is very uneconomical. Solar street lights are simple to install and have a long service life. In addition, the rural roads are so narrow and small that they do not require high LED light sources, so they are suitable for installing LED solar street lights.

Second, home backyard

If there is an illuminated LED solar street light in the backyard, it can be said to be very convenient, and because of the simple installation, it can also save a lot of electricity bills, and it can be turned on and off, which is very worry-free.

Three, outdoor camping

The most scarce thing from outdoors tonight is light. If you install LED solar street lights in some places that are very suitable for camping, it will not only solve the main problems of campers, but also ensure the safety of these people to a certain extent. The size of the street lamp is very suitable for installing energy storage batteries in it as a backup light at night. Moreover, the installation cost is not high, and there are many people who benefit, so why not do it.

Yangmeitou Zhongxi Grapefruit Park LED lamps

Since its opening in March in Touchongxi Pomelo Park, Yangmei District, it has been loved by many parents and children. The children don’t want to go home after playing but are just a group of climbing game groups in the inclusive playground. One of them resembles a banana. It’s a long white stripe that is regarded by children as a “slide,” but it looks strange. How do you play it? Arouse public discussion.

Yangmeitou Zhongxi Grapefruit Park LED lamps

In this regard, the Municipal Bureau of Public Works clarified that this is an LED lamp in the play gear, which emits blue light at night, not a slippery ladder, to remind the children not to slip anymore.

According to the Works Bureau, the Touchong River Pomelo Park opened in 2016 is located at Lane 256, Section 1, Ruixi Road, Yangmei District. It covers an area of about one hectare. The construction of the park’s inclusive playground started in October last year and was completed in February this year. Opened in March, the inclusive playground is equipped with a set of combined swings (parent-child, bird’s nest, vertical nets, etc.), a set of LED light climbing sets, a set of bunkers, and two sets of bounce beds providing a variety of changes, Challenge unlimited game space.

The Bureau of Public Works reminded us that the LED light climbing group provides different climbing spaces for children aged three to ten years old. They can have fun in the play equipment set. The play equipment includes LED light poles, which can be used as night lighting, from 6:30 pm to The lights are on at 0:30 in the morning and cannot be used as climbing and sliding ladders. Parents who bring children to play should pay special attention to avoid danger.

Signify cooperates with the New York State Power Authority to transform more than 500,000 sets of street lights

Signify recently announced its cooperation with the New York State Electricity Authority (NYPA) to support the state’s promotion of the New York State Smart Street Light Project. The project was proposed by Governor Andrew Cuomo in early 2018 and is committed to energy-saving retrofits of more than 500,000 sets of street lights in the state with sustainable alternatives.

Signify cooperates with the New York State Power Authority to transform more than 500,000 sets of street lights

Through this project, the New York State Power Authority provides financial, logistics, technical, and information support for cities that want to upgrade their street lighting systems. With the help of smart interconnected LED street lights and Signify’s Interact City IoT lighting system, cities can reduce energy consumption and carbon emissions and make cities more livable. Since the start of the project, more than 50,000 sets of LED street lights have been installed or are being installed.

In addition, as an important part of the project, the New York State Power Authority has designed an innovative financial model to provide low-interest loans for the upgrade of lighting systems in various cities and purchase lighting assets from local equipment vendors. Signify is not only the technology provider for this project but also a trusted advisor and strategic partner for the New York State Power Authority and cities.

“In addition to illuminating the roads, road lighting systems are also an indispensable part of the construction of smart cities. The application of smart interconnected LED lighting systems can not only reduce electricity and maintenance costs, but also give full play to the value-added benefits of the lighting system.” President and CEO Gil Quiniones said.

Rochester street lighting project leader Abebe Woldemariam gave a positive evaluation of Interact City. “The platform provides more possibilities for city management and maintenance,” he said. “With Interact City, we can remotely monitor the system through the central panel to quickly identify maintenance needs. If any problems occur, the system will proactively notify the administrator. Solving the problem before it affects the normal life of the residents. This is great.”

According to the introduction, the municipal management department can install various sensors on the smart connected street lights under the jurisdiction of Interact City to improve the quality of urban life and management level. By loading tilt detection, vibration and noise sensors on smart interconnected street lights, municipal management departments can maintain street lights and light poles in time, identify areas that need noise reduction measures, and protect roads and drivers. Interact City’s open application interfaces (APIs) can share the information collected by sensors with the information systems of the fire brigade, medical rescue and other emergency agencies to help them respond more quickly. In addition, signify’s BrightSites and other smart light poles can also be used as access points for mobile phone networks and wireless networks (Wi-Fi), or provide charging for electric vehicles.
