2021 Global LED Lighting Market Outlook and Analysis of Opportunities and Challenges

According to TrendForce’s latest report “2021 Global LED Lighting Market Report-Lighting-Level Packaging and Lighting Product Trends (1H21)”, the global LED lighting market outlook is more optimistic than previous estimates, and the global LED lighting market scale is estimated in 2021 There will be a chance to grow 5.1%. COVID-19 is spreading rapidly around the world, which has curbed the demand and consumption of LED lighting to a certain extent in the short term. In the medium and long term, there are still many uncertainties in the impact of the new crown epidemic on various industries. However, in order to alleviate the negative impact of the epidemic on the economy, governments around the world have implemented different levels of fiscal stimulus and monetary easing policies. The economy is recovering extensively, and downstream LED lighting demand is highly correlated with macroeconomic development, and lighting will benefit from this. LED lighting products are necessities for people’s production and life, and the rigid market demand still exists. During the epidemic, the demand for the home lighting market has not decreased but increased, which demonstrates this essential characteristic. In addition, lighting products are further developed to digital intelligent dimming and control lamps. It is believed that the future lighting industry will also pay more attention to the intelligent systemization of products, human-caused health lighting, and market demand for segmented applications. TrendForce estimates that it will reach US$44.3 billion in 2025. 2021 Lighting Market Key Market Trend Analysis: Smart Lighting, Human Factor Lighting, Niche Lighting.

2021 Global LED Lighting Market Outlook and Analysis of Opportunities and Challenges

1. The government’s investment in smart building lighting and the development of smart urbanization will drive the demand for the smart lighting market to increase. Under the influence of the epidemic in 2020, the smart lighting market will perform significantly better than the general LED lighting market, mainly due to the cost adjustment of smart lighting products and terminals Consumer demand for smart lighting systems continues to increase, driving the market momentum for Connected Lighting. From the perspective of application scenarios, commercial intelligent lighting combines human health requirements with intelligent lighting to improve light quality and energy-saving control. Although it is affected by the epidemic in the short term, it will show rapid growth in the long term. 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 market demand for smart lighting in this sector is driven. In addition, the epidemic has accelerated the penetration rate of smart lighting products. It is the market with the highest growth rate in 2020, with an annual growth rate of 27%. . In the field of outdoor smart lighting, despite its relatively small market size, its rapid growth rate is mainly attributed to the promotion of energy-saving policies and economic stimulus programs of various governments. Including the economic stimulus plan for infrastructure construction in Europe and Australia, as well as the US FAST Act and Highway Trust Fund. In addition, in response to the global boom in smart city construction, along with the development of IoT and 5G technology, TrendForce said that the smart street lamp market will officially enter the stage of high-speed replacement and development.

2. Human lighting is currently mainly reflected in the application of high color rendering lighting and healthy lighting. GE Current and Nichia have worked together to apply GE Current TriGain technology to commercial lighting to achieve high color saturation and color rendering ( CRI/R9), and will not sacrifice luminous efficiency. According to TrendForce’s survey, commercial lighting products using TriGain technology performed well in 2H20. Health lighting products have the opportunity to introduce 435nm light sources to reduce blue light hazards. In the future, there will be opportunities to expand to school education venues and improve the development of the lighting market.

3. The plant lighting LED market in the niche lighting market has become one of the fastest-growing lighting applications. Firstly, it is attributed to the acceleration of the legalization of cannabis cultivation in North America, and the new crown pneumonia epidemic has made the medical and entertainment cannabis market scale fast increase. Second, the impact of the epidemic on the food supply chain has gradually emerged, and investment in indoor planting and agriculture has once again heated up, driving the replacement of lighting equipment and increasing demand for new additions. In addition, the cost of lighting LED products has dropped significantly, including the unit price of red LEDs and medium and high-power lamp beads, which reduces the overall cost of lighting. According to TrendForce’s research, the demand for the plant lighting market will break out in 2020. Most manufacturers continue to launch new and higher-spec LED products, such as OSRAM, Samsung, Cree, Lumileds, Seoul Semiconductor, etc. This move will accelerate the replacement of traditional lighting products with LEDs. 2021 Lighting Industry Market Development Opportunities and Challenges The driving forces of the future lighting industry market mainly come from: products with higher energy efficiency, lower cost, lighter weight, smaller size, easier to install lighting devices, and more convenient wisdom control. With the development of IoT technology, smart control will become the main driving force of the future market.

In terms of health and safety, at the same time, the next generation of lighting products must have higher quality and quality (reflected by contrast, brightness, etc.), and more comfortable. Finally, looking at the revenue of lighting manufacturers, under the dual impact of the Sino-US trade conflict and COVID-19, lighting manufacturers will face a more severe market test in their lighting revenue performance in 2020. However, TrendForce Consulting observes manufacturers’ revenue and product performance, and most manufacturers continue to deepen their efforts in the professional lighting and smart lighting markets. As the demand for intelligent lighting products increases, the revenue of some companies that have deployed the market earlier will see a significant decrease in revenue in 2020.

MIT launches new silicon-based LED

Recently, the Massachusetts Institute of Technology research team announced that the current design of a very practical silicon-based LED, it will use the forward bias method, compared with other silicon-based LED brightness increased by 10 times.

MIT launches new silicon-based LED

The new silicon-based LED developed this time adopts the forward bias method, and at the same time, the combination of the PN junction in the LED is changed, which successfully improves the photoelectric energy conversion efficiency of silicon materials, further improves the brightness of the silicon-based LED, and reduces the LED’s manufacturing cost.

For silicon materials, this is one of the most widely used materials by mankind, mainly used in the field of manufacturing semiconductor devices and integrated circuits. However, due to the particularity of silicon material, it has not been involved in the optical field, so silicon-based LED has not been realized.

The PN junction in the light-emitting diode includes a P area and an N area, which will determine the luminous efficiency of the diode. Among them, the N zone is full of exciting free electrons, and the P zone has positively charged holes that attract electrons in the P zone. As the electron rushes into the hole, the energy level of the electron drops sharply, and the energy difference can be released. However, different semiconductor materials have different electron and hole energies, so the energy released has certain differences.

Currently widely used materials such as gallium nitride and gallium arsenide are direct bandgap materials. They are often used in LEDs. The minimum conduction band and maximum valence band have the same electronic momentum. The electrons at the bottom of the conduction band and the top of the valence band The holes can emit light through radiation recombination, with a high recombination probability and high luminous efficiency.

As an indirect bandgap semiconductor material, silicon has different momentum values between the minimum conduction band and the maximum valence band. It tends to convert energy into heat rather than light, so its conversion speed and efficiency are not as good as others. material.

And this year, the research team led by Erik Bakkers of Eindhoven University of Technology in the Netherlands successfully developed a new type of silicon-germanium alloy luminescent material using VLS to grow nano-silicon wires, which successfully improved the above problems, and developed a new type that can be integrated through this material. To silicon-based lasers in existing chips. The successful development of this laser may significantly reduce the cost of data transmission and increase efficiency in the future.

This time, the MIT team further improved the use probability of silicon materials, and proposed a new connection method for N-zone and P-zone, changing the N-zone and P-zone from the traditional parallel arrangement to vertical stacking, so that the diode Keep electrons and holes away from the surface and edge areas to prevent electrons from converting electrical energy into heat, thereby improving luminous efficiency.

The American National Institute of Standards and Technology commented on this new silicon-based LED: “If you need low-efficiency, high-energy-consumption optical devices, then this new silicon-based LED is suitable for you. This LED is better than the current market. There are products, the manufacturing cost is much lower, not to mention the existing LED products have not been integrated on the chip.”

Rajev Ram, a researcher on the MIT research team, said that the characteristics of silicon-based LEDs are very consistent with the needs of short-range sensing, and revealed that the team will develop an all-silicon-based for short-range distance measurement for smartphone platforms. LED system.

It is reported that the new silicon-based LEDs introduced this time will be displayed at the IEEE International Electronic Devices Conference, and will have a wider range of application scenarios in short-range sensing. At the same time, the MIT research team is also preparing to integrate this new silicon-based LED into the CMOS chip and deliver it to GlobalFoundries for production in Singapore.

Explosive growth in demand for LED-related products

A few days ago, the China Lighting Association released the “Report on China’s Lighting Industry Exports in the First Three Quarters of 2020.” The report shows that the industry’s recovery trend is relatively obvious, mainly because after the epidemic, the industry’s rapid resumption of work and production has made up for the global market’s capacity gap caused by the epidemic.Explosive growth in demand for LED-related products

LED industry continues to pick up, exports in the first three quarters increased by 5.45% year-on-year

In the workshop of an LED company in Shenzhen, the reporter saw that the workers were very busy and the machines were in full production. According to the person in charge of the company, the business has been poor in the first half of this year. The orders received last year were delayed due to the epidemic. In the second quarter, construction started sporadically. However, since July and August, orders began to increase.

Chen Fuquan, Chairman of Shenzhen Sacred Heart Technology Group: There were some crises at the beginning of the year, but after our new products were developed, new products grew from scratch and grew rapidly from scratch. Therefore, from January to October this year, we increased by 50%. the above.

Industry insiders told reporters that the reason for the increase in orders for the industry’s recovery is that the domestic control of the epidemic is relatively fast, and many overseas orders are flowing domestically. In addition, the backlog of domestic orders has entered the late stage of implementation and LED exports have seen a substantial increase.

Li Guanqun, Secretary of the Board of Directors of Mulinsen Co., Ltd.: In recent years, most of the industry’s production capacity has been transferred to Southeast Asia and overseas, but when the domestic epidemic is better than overseas, many orders are transferred to domestic manufacturers. For example, the manufacturing bases in Ji’an and Xinyu in Jiangxi have been operating at full capacity since August.

According to the “Report on China’s Lighting Industry Exports in the First Three Quarters of 2020” issued by the China Lighting Association, in September 2020, China’s lighting industry exports were US$5.113 billion, a year-on-year increase of 44.18%, which was the largest in a single month this year. The growth rate has achieved double-digit growth for four consecutive months since June. Among them, the export value of LED lighting products was US$3.4 billion, a year-on-year increase of 40.5%, and the cumulative export value of LED lighting products from January to September this year was US$23.46 billion, a year-on-year increase of 5.45%.

The development of 5G smart street lights is very important

Smart street lights are the most common and densest infrastructure in cities. With the advent of the 5G era, every humble street lamp may be integrated into multiple modules such as charging piles, video surveillance, environmental monitoring, light pole screens, etc.-as “smart street lights”, can not only collect information, but also publish Information not only has the opportunity to become an important part of the construction of smart cities, but also an important link in the construction of 5G base stations in the future.

The development of 5G smart street lights is very important

1. Smart street lights: an important entrance for smart city construction

If the Internet of Lights, the Internet of Things, and 5G networks are the context of smart cities, as multi-purpose poles, information poles, and smart poles, smart street lamps are the nerve endings of these systems, allowing smart municipalities and smart cities to land in the urban lighting business. In the past, multiple functional poles were set up on a city road. Integrating these functions into one pole can greatly save costs. For example, if citizens encounter danger when traveling at night, they can call and locate quickly with one touch, which greatly reduces the chance of accidents and accidents. People can also learn about the day’s temperature, air quality, and other environmental indicators through the display screen of the light pole.

In some creative parks, beautiful multi-functional smart light poles use the display screen to broadcast videos, play music and radio, and provide functions such as safe science popularization or advertising, and allow people to enjoy free 5G Wifi signals at any time. The lighting of the street lamp can automatically adjust the brightness of the lighting according to the changes in the morning and evening of the day, and it can also activate the power saving mode in the middle of the night. Whether in the city or the community, these functions have increased the convenience of our life and office and escorted everyone to travel safely. For city managers, data can be collected through a platform, and intensive management can also be achieved, reducing labor.

2. Edge Computing Service: Smart City Micro Center

As a “new public infrastructure” for smart city construction, excellent locations, and wide distribution make smart street lights a good carrier for 5G base stations.

Optimized 5G network is the basis of many “5G+” innovative applications; smart street lights equipped with a variety of devices, empowered by ICT (information and communication) technology, can provide efficient and energy-saving applications in municipalities, transportation, security, and environmental protection. A new type of public service; a reasonable layout of urban smart street lights network can provide the smart city brain with massive city operation data in real-time, which is the basis for building a digital twin city. It can be said that smart light poles are like “smartphones” configured for cities, which can help people perceive every street in the city.

The light environment design system research center of the Academy has completed the planning, design, and project implementation of urban landscape lighting for the core area of the Qingdao Shanghai Cooperation Summit, Bengbu, Hebei, Hengshui, and Lishui, Zhejiang, as well as multiple roads of 5G+ wisdom. Street lamp planning and design, smart light pole system engineering and construction.

Through the smart street lamp management platform, the unified management of smart street lamp heads, video monitoring, environmental indicators, and other data is realized, and based on the real-time collected data, intelligent statistical analysis is performed to provide intelligence for the city’s municipal management, emergency management, environmental monitoring, etc. And information services. In the future, the digitalization and intelligence of society will develop at a high speed. Smart IoT and smart street lights will usher in development opportunities. The Light Environment Design System Research Center of the Institute will continue to explore the integration of “5G + smart lighting” in urban, landscape, architecture, and indoor environments. Application, help the development of the city, empower a better life.

New LED challenges laser lame

LED lamps are already the mainstream equipment of automobiles, with two major advantages of energy-saving and durability, making traditional halogen lamps or HID lamps have gradually disappeared; due to the small size of LED, there are better flexible applications in the design of headlights. A major breakthrough in LED technology, with stronger lighting distance and energy-saving effects, can even challenge more advanced laser headlights.

New LED challenges laser lamps

Shuji Nakamura was the winner of the 2014 Nobel Prize in Physics, also known as the father of blue LEDs. Based on the research results of blue LEDs, he produced a pure white LED lamp. Under the supervision of Nakamura Shuji, SLD Laser launched a new LED. White light, this new LED luminaire has a lighting distance of up to 1 km and consumes less energy than traditional LEDs, pushing the capabilities of LED luminaires forward.

The performance of SLD Laser’s LED lamps is comparable to that of laser headlamps. At present, both BMW and Audi have laser headlamp technology. Laser lamps use laser beams to project to the reflector to produce a strong beam, which consumes less energy than ordinary LEDs, but costs Expensive and only equipped in high-end cars; LED lights developed by SLD Laser are already comparable to laser lights in performance. In addition, they are low in cost, easy to replace and small in size. In order to verify the performance of the lights, SLD Laser won the Baja 1000 off-road rally champion Cameron Steele’s car is equipped with a new type of LED light. This group of lamps is used for night searches. Due to the powerful performance of this LED lamp, due to the differences in lighting regulations in various countries, the new LED will be the first to be used in competitions or special purposes. It may replace laser headlights in commercial vehicles and stabilize the dominant position of LED lamps.

DALI Alliance joins IP-BLiS

It is reported that the DALI Alliance has recently joined the “IP Building and Lighting Standards” market interest organization IP-BLiS to support the integration of Internet Protocol (IP) transmission and security mechanisms to simplify the deployment, supply, and protection of complex building systems.

DALI Alliance joins IP-BLiS

IP-BLiS was jointly launched by BACnet International, KNX Association, OCF, Thread Group, and Zigbee Alliance in June 2020. Together, these standards organizations support the widespread adoption of IP-based security, a multi-standard infrastructure, as the backbone of lighting and building automation solutions in commercial buildings.

The use of IP as a common network protocol allows IT systems and building services (including lighting control) to operate on all configurations that are secure, IP-based. Therefore, building operators can look forward to end-to-end addressing and security, easy connection between previously independent applications; unlimited scalability; better, faster, and lower-cost integration; and great flexibility Sex and physical transmission and application choice.

Paul Drosihn, general manager of the DALI Alliance, said: “On behalf of all the leading lighting companies that make up our members, we are very happy to join IP-BLiS and help solve the complexity and connectivity barriers in smart buildings.” “Internally, our team is working Significant progress is made towards the first IP-based DALI specification, which will enable DALI networks to have wireless connectivity, as well as IP, addressing, and security.”

“DALI, as a leading digital lighting control protocol, joined IP-BLiS, and once again emphasized the importance of making commercial buildings more sensitive to user needs through the promotion of security, IP-based multi-standard, IoT-based IoT solutions. The vision of IP-BLiS. As DALI becomes a new member, we see that IP-BLiS has been confirmed in its previous activities and succeeded in the future roadmap of IP-BLiS,” IP-BLiS Chairman CastoCa Avate said.

IP-BLiS will speak in a unified language to facilitate IP-based network connections with common transmission and security requirements, and organizations will not create their own standards. Each participant is responsible for specifying his own technology. This allows companies to decide which solution is best for their business and use cases.

Similarly, IP-BLiS attempts to adjust the industry’s safety requirements, rather than reinvent them. Security issues are discussed in the IP-BLiS blog, titled “Common Myths About IP Networking for IoT”.

Changzhou has achieved remarkable results in promoting green LED lighting

Since the “13th Five-Year Plan”, the city’s urban lighting facilities have increased from 390,000 to 710,000, but the annual electricity expenditure has decreased correspondingly, from 94.79 million RMB to 69.44 million RMB, a decrease of 36.5%.

Changzhou has achieved remarkable results in promoting green LED lighting

“There are more street lights, but fewer electricity bills. This is due to the city’s continuous promotion of LED transformation, the simultaneous implementation of the construction and application of smart lighting systems, and the improvement of energy consumption management through scientific design, reasonable regulation and other management methods.” Municipal Urban Lighting Management in charge said.

Since 2017, our city has comprehensively promoted the LED transformation of urban road street lights. Up to now, nearly 28,700 street lights on 244 roads in Zhonglou District and Tianning District of our city have basically achieved full LED coverage, saving nearly 8 million RMB in electricity bills each year, which reduce carbon emissions by 12,000 tons.

At the same time, the city has innovated system construction and independently developed a single-lamp control platform with patents and intellectual property rights-“NB-IOT-based intelligent lighting system”, which is a single-lamp control device equipped with 5G communication technology for lamps. “The single-lamp control system combined with the single-lamp controller can realize the automatic point-to-point switching, dimming, automatic fault reporting, data management and other functions of each street lamp.” said Chen Yang, section chief of the Facilities Management Section of the Municipal Urban Lighting Management Office. Which street lamp fails, mainly depends on staff inspections or citizens’ feedback, and now the staff can find out in time through the single-lamp control platform, which provides a guarantee for rapid processing. At present, the coverage rate of single light control of urban roads and street lights is nearly 80%.

Chen Yang introduced that by independently developing the lighting system and formulating “data standards” and “communication protocols”, the Municipal Urban Lighting Management Office can realize the access of any brand of lamps and single lamp control equipment, for the subsequent operation and maintenance and long-term management of lamps laid a solid foundation. Using the “Internet +” means, the operation and maintenance of urban lighting facilities has been transformed from “car patrolling and running” to “big data running”, and the number of lamps maintained per capita increased from 7,500 to 12,000, an increase of 60% Under the circumstance, the lighting rate is 99.4%, which is always far higher than the national standard of 98%, and it also exceeds the national civilized city assessment standard of 99%.

On the basis of the single-lamp control system, the Municipal Urban Lighting Management Office further combined GIS, three remotes, mobile inspection, intelligent warehousing and other information systems to integrate and develop the “Changzhou City Urban Lighting Integrated Management Platform” which was officially launched in June 2019. The commissioning has further improved the urban lighting operation and maintenance and public service capabilities. In the “Provincial Urban Green Lighting Evaluation” work, the system was highly evaluated by the Provincial Housing and Urban-rural Development Department and its counterparts across the province. It is considered that its advanced technology concept, innovative construction mode, and overall system practicability have reached the industry leading level.
