Traditional lighting manufacturers are moving towards intelligent transformation

At present, smart lighting products are mainly distributed in four major areas: industrial and commercial, residential and household, outdoor lighting and public lighting. TrendForce’s latest report “2021 Global LED Lighting Market Report-Lighting-Level Packaging and Lighting Product Trends (1H21)” pointed out that in the field of smart home lighting, in response to the development of the smart home market, especially in the high-end residential market, the overall growth of this sector demand for smart lighting, coupled with the accelerated penetration of smart lighting products by the epidemic, will be the market with the highest growth rate in 2020, with an annual growth rate of 27%.

Traditional lighting manufacturers are moving towards intelligent transformation

Although smart lighting is growing rapidly in the residential and home furnishing sectors, the current market recognition is not high. According to a data report released by iiMedia Consulting, among the smart home products, the interviewed netizens have the highest awareness of smart TVs (42.6%), but have a low understanding of products embedded in systems such as smart surveillance and smart lighting. The recognition of smart lighting accounts for only 13.5%.

In addition, most of the current smart home products are single product intelligence or single system intelligence, and it is difficult to achieve common interconnection at the level of the entire smart home system to provide consumers with a better user experience. Under the combined influence of these factors, smart home lighting products are facing considerable difficulties in market promotion and popularization.

Liang Jiehui mentioned, “Current smart home lighting products are more transitional products. For individual users, many products on the market are not very friendly in terms of selection, installation, network distribution, and use. So now the penetration rate of the product is relatively low. In addition, the current users who choose to use smart home lighting are basically hardcore smart product enthusiasts. Therefore, if the product can actively understand customer needs and is easy to install and use, smart lighting products can really explode.”

For market promotion and popularization, channels are also an important factor. Traditional lighting products are mainly sold in offline channels, but now users are becoming more and more accustomed to buying products online, especially under the influence of the new crown pneumonia epidemic last year. According to industry insiders, two different sales channels, online and offline, have their own advantages and disadvantages, with strong offline experience and low traffic, and strong online traffic with low experience. In the future, online and offline may be integrated to achieve true O2O. Prior to this, traditional lighting companies may wish to cut into smart products through mature platforms in the early stage. In addition to having a good boost to the intelligent transformation of enterprises, the risk will also be relatively low.

The global LED market output value is estimated to reach 16.53 billion U.S. dollars in 2021

TrendForce’s Global LED Industry Database report shows that the LED industry will be hit by the new crown pneumonia epidemic in 2020, and the output value will not only decline but also a rare decline in previous years.

The global LED market output value is estimated to reach 16.53 billion U.S. dollars in 2021

With the advent of vaccines in the first half of 2021, long-term suppressed demand will bottom out. It is estimated that the global LED market output value will rise this year, reaching 16.53 billion U.S. dollars, an annual increase of 8.1%. The main growth momentum comes from automotive LEDs, Mini LED, and Micro LED, as well as commercial-related displays and invisible light.

TrendForce expects that the sales performance of new energy vehicles will grow substantially this year, and new models of traditional fuel vehicles will accelerate the introduction of LED lighting solutions. This will drive the penetration rate of automotive LEDs to continue to rise since 2020. It is expected that the output value in 2021 will be expected to reach 2.93 billion US dollars, an annual increase of 13.7%, and its growth momentum ranked first among all LED application categories this year.

Secondly, the demand for new display applications including Mini LED and Micro LED will explode in 2021. Among them, thanks to Apple’s new-generation iPad Pro 12.9-inch and the introduction of Mini LED backlight technology in Samsung TVs, Mini LED backlight applications will increase significantly. The total output value of this company is US$380 million, with an annual growth rate of 265%, making it the second-largest growth block.

Third, the display market, driven by new application scenarios such as conference all-in-one displays, 5G 8K ultra-high-resolution displays, home theaters, and virtual production, has become the focus of market attention in recent years. It is estimated that the output value will reach 1.78 billion US dollars, an annual increase of 12%, making it the third-largest growth block this year.

It is worth mentioning that in the invisible light LED market, the UV-C LED market has attracted much attention due to the impact of the new crown virus epidemic. Brand manufacturers have successively increased their awareness of sterilization and purification, and the optical power of UV-C LED products continued to increase. Among them, relevant companies in China, Europe, South Korea, and Japan all plan to introduce new home appliances into UV-C LED, and plan or are importing more than 35 UV-C LED brand manufacturers. It is estimated that many applications of infrared and ultraviolet will push up the overall invisible light LED market output value to 830 million US dollars, an annual increase of 27%.

LED applications in a variety of fields require a variety of power supply topologies to support

Input voltage range, number of LEDs driven, LED current, isolation, electromagnetic interference (EMI) limits, and performance are all relevant design parameters. Most of the LED drive circuits can be divided into the following topology categories: buck, boost, buck-boost, SEPIC, and fly back.

LED applications in a variety of fields require a variety of power supply topologies to support

The buck regulator shown in the first picture can be used in situations where the output voltage is always less than the input voltage. In Figure 1, the buck regulator changes the conduction time of the metal oxide semiconductor field-effect transistor (MOSFET) to control the current into the LED. The voltage can be measured across the resistance for current detection; the resistance and the LED are connected in series. Driving the MOSFET is a major challenge in the design of this method. From a cost and performance point of view, it is recommended to use an N-channel FET that requires a floating gate drive. N-channel FETs need to use a drive transformer or a floating drive circuit, both of which can maintain a voltage higher than the input voltage.

Figure 1 also shows an alternative buck regulator (Buck#2). In this circuit, the driving of the MOSFET is related to grounding, which greatly reduces the demand for the driving circuit. The method of this circuit to detect the LED current is to monitor the FET current or a current detection resistor connected in series with the LED. If the latter is adopted, it is necessary to use a level shift circuit to send this information to a grounded power source and complicate the simple design. The boost converter, also shown in Figure 1, is used when the output voltage is always greater than the input.

This kind of topology design is easy, because the driving of MOSFET is related to grounding, and the current detection resistor is also a grounding reference type. The disadvantage of this circuit is that it cannot limit the current through the inductor when it is short-circuited. You can use a fuse or a circuit breaker as a fault protection device. In addition, there are some more complex topologies that can provide this type of protection.

Figure 2 shows two buck-boost circuits that can be used in situations where the input voltage may be greater or less than the output voltage. These circuits have the same folding characteristics as the aforementioned two-buck topologies and are related to the position of the current detection resistor and the gate drive. The buck-boost topology of Figure 2 shows a ground-referenced gate drive.

This topology requires a level-shift current detection signal, but the reverse boost-buck topology has ground-referenced current detection and level-shift gate drive. If the control IC is related to the negative output, and the current detection resistor is exchanged with the LED, the reverse boost buck topology can be configured in an effective way. As long as the IC is properly controlled, the output current can be measured directly, or the MOSFET can be driven directly.

The LED lighting market is expected to grow 5.1% this year

The new crown pneumonia has brought many uncertainties to various industries. Governments of various countries have implemented different levels of fiscal stimulus and monetary easing policies. The downstream LED lighting demand is expected to benefit. According to TrendForce’s latest lighting market report, the global LED lighting market size is estimated this year There will be a chance to grow 5.1%.

The LED lighting market is expected to grow 5.1% this year

LED lighting is moving towards digital intelligent dimming and control of lamps, towards intelligent systemization, human health lighting, and market demand for segmented applications. TrendForce estimates that the market size will reach 44.3 billion US dollars in 2025.

Under the influence of the epidemic last year, the smart lighting market performed significantly better than the general LED lighting market. The cost adjustment of major smart lighting products and the increasing demand for smart lighting systems from end consumers have driven the momentum of the networked lighting market.

The growth of smart home lighting in the high-end residential market has driven the market demand for smart lighting in this sector, and the epidemic has accelerated the penetration rate of smart lighting products. The market with the highest growth rate last year had an annual growth rate of 27%.

The process of legalization of cannabis cultivation in North America is accelerating, and the investment and construction of indoor farming agriculture is heating up again, driving the replacement of lighting equipment and increasing demand for new additions. The cost of lighting LED products has decreased significantly, including the unit price of red LED and medium and high-power bulbs, which makes the overall lighting construction cost reduce.

LED plant light and other regulation of jujube production period

In order to catch up with the harvest time before the new year when the price of jujube is good, jujube farmers usually adjust the production period by lighting at night. However, the farmers choose the lamps themselves to adjust the production period, and the success rate is very low, even less than 50%. The Fengshan Branch of the Agricultural Research Institute of the Council of Agriculture has studied that the use of LED lamps to adjust the ratio of red to blue light of 6 to 4 can effectively promote the early blooming of the mid-leaf species of jujube, which can come and bloom within 15 days of light.

LED plant light and other regulation of jujube production period

Jujube is a tropical fruit tree, the natural production period is from late August to early October, and it can be harvested in mid-February of the following year. However, jujube is a popular fruit for gifts during the New Year, and the price is good before the holiday. Farmers often use night lights to increase their accumulation of light, which promotes the early blooming of jujubes and adjusts the production period; however, red and blue light affect crop growth. The effect of production adjustment varies with date varieties. In the past, farmers used fluorescent lamps, halogen lamps, and other lamps to produce adjustments on their own, but the effect was not good.

The Agricultural Laboratory Fengshan selected LED lamps that were energy-saving and could adjust the ratio of red and blue light and conducted a light-emitting period adjustment experiment for the mid-leaf and snow honey, which are the most cultivated jujube varieties in China. The red light (600-680nm) in the light source has the effect of urging flowers, and the blue light (400-500nm) promotes plant growth. Fengshan branch, therefore, supplements the light for 8 hours after sunset every day and continues the experiment for 30 days. The experiment found that the middle-leaf jujube was illuminated at night with an LED lamp with a ratio of 6 to 4 red and blue light, and the effect was remarkable.

According to Guo Zhanhong, an assistant researcher at Fengshan Branch, it takes 1 to 1.5 months for jujubes to bloom to fruiting, and it takes 130 to 140 days for the mid-leaf jujube to grow. Therefore, the lights will be supplemented at night from July, and the flowers will begin to bloom on July 15. The harvest will be available in mid-January of the following year; after the flower is successfully urged, the light can be stopped until the length of the fruit is 3 cm in size, and then the red and blue light ratio is 4 to 6 night light, which can promote the growth of plant leaves and branches and help Strengthen the nutrient absorption capacity of fruit trees and make the fruit quality better.

However, the fruit growth period of the snow honey jujube is only 105 days. It is harvested too early, and there is no output to sell before the new year. Instead, farmers have the need to postpone its production period. According to the experiment of the Fengshan branch, the red and blue light sources were irradiated with a ratio of 4 to 6 light sources in July to prolong their vegetative growth. After 30 days of lighting, the lights were stopped and the jujubes could be postponed until September.

Guo Zhanhong pointed out that in the past, farmers used lamps for “indigenous steelmaking” and did not know the nature of the light source spectrum. Therefore, the effect of stimulating flowers was not seen after a long time. Fengshan branch tested and determined suitable varieties and their light source spectrum ratios to assist farmers in doing so. Accurate production adjustment, but this 4-year research project is currently underway for 2 years. The effect of the early mid-leaf jujube production period is more significant, and the effect of the delayed production period of snow candied jujube remains to be seen.

Many LED companies announced to increase product prices

Under the epidemic, the cost of raw materials, transportation, and other expenses will increase. In the future, the global supply chain will continue to face uncertain factors. Based on this, since the end of 2020, many domestic and foreign companies have announced an increase in product prices.

Many LED companies announced to increase product prices

Signify’s increase notice shows that due to the surge in demand for electronic components, tariff costs have risen sharply, supply chain capacity shortages, supply chain costs increase, transportation costs increase, product delivery dates are uncertain, manpower shortages, and many other uncertain factors Due to difficulties, Signify decided to re-adjust the price from February 1st.

Landvance Taiwan’s general distributor and OSRAM digital lighting system distribution partner, Ling Teng Technology, announced that the cost of international raw materials has hit a new high in recent years. At the same time, short-chain supply and sea freight rates have risen and shortages due to the impact of the epidemic. The situation in the cabinet was severe, and the company could not bear the pressure of operating costs and decided to make slight adjustments to prices starting from January 1.

Derun Electronics said that due to the epidemic, the mining volume of domestic and foreign non-ferrous & precious metal mines will decline in 2020, and the listed prices of copper, silver, and other metals have bottomed out in March and have risen all the way. At the beginning of January 2021, the price of copper has exceeded 60,000 RMB/MT, and the price of silver has exceeded 5,100 RMB KG, rising by as much as 60% and 80%, resulting in a substantial increase in the cost of stents.

In addition, due to the recent rebound in orders and the decrease in shipping, there is a serious shortage of copper and rubber materials. In order to meet the delivery, the unit price of the purchased materials can only be increased, and the cost has further increased. After financial accounting, many products have suffered serious losses.

Therefore, DEREN Electronics decided to increase the price of its products and implement the new unit price from the new order.

Liangyou Technology stated that the price of copper materials has continued to rise, from RMB 52,000/ton in August 2020 to RMB 59,000/ton so far, with a price increase of RMB 7,000 per ton. In recent months, some models of the company have traded at a loss and are unable to bear the losses caused by the increase in materials. Therefore, all customers have applied for price increases. Orders confirmed before December 21, 2020, will still be traded at the contract price.

The Taiwanese professional lighting manufacturing company China National Electric Corporation (brand name East Asia Lighting) announced to distributors that due to the sharp increase in raw materials, the production and supply chain will be affected. Therefore, the company will increase the price of East Asia brand lighting products, including T5/T8 light source, T5/T8 light source, LED light source, and LED light source.

China’s LED plant lighting helps Qatar’s agricultural development

Compared with the surrounding yellow sands, the vegetable sheds in the production area have a unique cave, and there are various vegetables in an orderly arrangement and in different growth periods. These vegetables are not grown on the ground but are planted in a multi-layered container for soilless cultivation. Each row of growing vegetables is equipped with a slender pipe for “water supply”. The technician said that this is not ordinary water, but for vegetables and nutrient solutions for growth.

China's LED plant lighting helps Qatar's agricultural development

The reporter saw that a variety of special lamps are installed on the top of the greenhouse to promote the photosynthesis of vegetables. The color and intensity of the light can be adjusted as required to cultivate green and purple vegetables. The shed is equipped with air conditioners, sensors, and computers, which can regulate temperature, humidity, and light. The technicians picked off a few leaves for demonstration and ate them, and said that the vegetables produced in this block are in short supply in the local market.

“China’s smart LED plant factory’s high-tech agricultural technology has greatly improved the economic benefits of our farm. This high-tech is not only an important guarantee for the development and growth of the farm but also helps promote the agricultural development of the region.” Farmer Fahad said.

“Alphagan Farm mainly produces seasonal vegetables. The machinery and equipment, seeds, and cultivation techniques required are imported from China and EU countries. The high-tech planting technologies are all from China. The farm will expand the production scale using China’s high-tech agricultural technology. China’s high-tech agriculture technology is very advanced, and the economic benefits produced are the most obvious. This will play a huge role in Qatar’s implementation of the Food and Vegetable Security Strategy’.” Fahd said.

Qatar is a desert country. There is no natural arable land in the country. Food, vegetables, and meat are mainly imported. In recent years, Qatar has paid attention to economic diversification and is committed to improving food production capacity, with special emphasis on vegetable production. For this reason, Qatar has introduced the “Food and Vegetable Security Strategy”, striving to increase the country’s vegetable self-sufficiency rate from 35% to 70% by 2023.

Fahd believes that in order to achieve the goal of 70% vegetable self-sufficiency, in addition to increasing the state’s investment in agriculture, it is also necessary to speed up the introduction of agricultural high-tech and comprehensive agricultural technology. China’s high-tech agricultural technology will undoubtedly help Qatar implement the “food Vegetable safety strategy”.

Fahd’s partner and general manager of the Smart LED Plant Factory Gao Yuntao said that the current comprehensive agricultural planting technologies such as hydroponics and three-dimensional cultivation techniques used in this farm can greatly increase land utilization, save water and fertilizer, and resist the effects of high temperature and humidity. Therefore, it is highly praised in Qatar. “Currently, the vegetables produced using the above-mentioned Chinese technology have grown from two varieties of 1 rapeseed and 1 lettuce three years ago to more than 30 high-priced varieties on the Qatar market, including 6 lettuce, 4 kale, 5 kinds of peppers and cabbage, spinach, celery, etc.”.

Gao Yuntao said that Alphadan Farm’s success in using China’s high-tech agricultural technology has attracted social attention. Qatar TV and other media have conducted interviews and reports on this, and some local farmers and businesses in Qatar have also come to learn from it.

Chinese Ambassador to Qatar Zhou Jian said that with the joint efforts of the Chinese and Qatar governments, the areas of cooperation between the two countries have been expanding, from traditional fields such as energy and infrastructure construction to high-tech industries. He also said that the highlight of the economic and trade cooperation between China and Qatar in 2020 is the high-tech industry cooperation. This fruitful cooperation has enhanced the level of economic and trade cooperation between the two countries and boosted the diversified economic development of Qatar.

Osram acquires shares in UVC LED company Bolb

It is reported that Osram acquired US company Bolb Inc through its venture capital arm Fluxunit. Approximately 20% of the shares have further enhanced its technology in UV-C light disinfection applications and consolidated its leading position in the light disinfection market.

Osram acquires shares in UVC LED company Bolb

Olaf Berlien, CEO of Osram Licht AG, said about the investment: “OSRAM already has a variety of UV-C light solutions for disinfection, including LED and traditional technologies. The strategic investment in Bolb strengthens our UV-C LED Expertise in the field, and makes Osram a leader in the non-visible light disinfection market.”

According to OSRAM, the future cooperation between the two companies in the field of scientific research will accelerate the industrialization of high-efficiency and high-performance UV-C LED. Unlike previous solutions, the LED-based disinfection system requires very little space and can be directly installed on equipment, such as faucets, washing machines, or ventilation systems. The space-saving disinfection solution has made an important contribution to the new crown.

Osram sees the prospects of LED in the light disinfection market

Bolb’s UVC LED lighting technology can disinfect water, air, and surfaces. Bolb’s LED technology can replace many existing UVC/invisible light disinfection applications based on mercury vapor lamps and other lighting technologies.

According to data from Allied Market Research, the current market value of UV disinfection solutions is approximately 1 billion euros. It is expected that this number will quadruple by 2027. Market researchers also predict that the share of UV-C LED solutions will grow steadily.

Currently, most UV-C disinfection applications are based on traditional lighting technology, usually mercury vapor lamps. Compared with these traditional lamps, UV-C LED technology has the potential to greatly reduce energy consumption while still providing the required high light output.

Compared with traditional lighting technology, LED provides many advantages for traditional lighting applications. UV-C LED promises to bring many benefits to manufacturers of disinfection solutions. These advantages include low energy consumption, long life, and greatly simplified system design due to the compact size of the light source.

The cooperation between Osram and Bolb is expected to overcome this technical obstacle. Thanks to the unique technical components of UV-C LEDs, Bolb has successfully achieved excellent efficiency values?far exceeding other products on the market.

Ulrich Eisele, head of Fluxunit, Osram’s venture capital division, said: “With Osram’s decades of experience in developing and manufacturing semiconductor products, this cooperation has laid the foundation for Osram and Bolb to lead the UV-C LED market.
