Ten new trends in LED industry

With the transformation of the national economy and the change of the international economic environment, the steadily developing LED market will face more severe challenges in the next 2015-2020 years. With the increase of cost, new elements such as industry restructuring, technology development, transboundary and intelligence will be more and more injected into the LED lighting industry. This article will sum up the ten new types of LED lighting.

1. Plant lighting

What's fun? At present, the application direction of LED agriculture is focused on plant growth lights, livestock and poultry farm lights, fish trap lamps, selective pest trap lamps and so on.

Where are the difficulties? Research has proved the feasibility of applying LED in agriculture, but there is still no accurate and reliable light source technology index system suitable for agricultural production in the development of agricultural LED light source, the product is promiscuous, production design is not standardized, lack of unified product standards and quality management; LED agricultural lighting source R & D cost is partial. High.

Who is playing? The intelligent LED lighting control technology of Taiwan Research Institute has been adopted in the agricultural land of bamboo shoots, asparagus, strawberries and grapes in Nantou, Hsinchu and Changhua areas of Taiwan, and has shown good planting results. Mainland China has Shenzhen federal heavy branch (West Delta) Electronic Technology Co., Ltd., Shenzhen Pan Ke Technology Co., Ltd., Dongguan biologic environment bureau.

Technology Co., Ltd., Foshan Liang Liang solid light source Research Institute, Shanghai Hongyuan Lighting Appliance Co., Ltd., Beijing central access technology Co., Ltd. and so on.

2. Visible light communication

What's fun? Without WIFI signal, you can download a movie for 0.2 seconds under streetlights. This is not a science fiction, but a visible optical communication technology (LIFI) that has already achieved results. LED lights are extremely fast. This flicker is a kind of process of opening and closing, and this process can undertake a mission to send information, thus producing visible light communication technology (LIFI).

Where are the difficulties? To achieve indoor ultra high speed optical wireless data communication, there are still many challenges to be faced. For example, device development, modulation and demodulation and codec technology, wireless channel transmission and multiplexing technology, communication system and architecture design and other related technologies need further optimization.

Who is playing? In 2012, The PLA Information Engineering University and other units have successfully developed 6 sets of application demonstration systems, such as VOD TV service, visible light new radio broadcasting, visible light network table lamp, visible light home base station, visible light near field communication, underground visible light communication and positioning. In April of this year, the US retail giant Taghit (Target) installed 1800 near 47 stores in the United States to install mobile phone navigation and push discount information based on visible light communication technology. In May, the world lighting giant PHILPS and the world's retail giant Carrefour fully launched the indoor navigation system based on PHILPS visible light communication technology (VLC) at the newly renovated hypermarket in Lille, France to help consumers find the goods needed faster.

3. UV LED

What's fun? Ultraviolet LED generally refers to the luminous center wavelength below 400nm LED, but sometimes when the luminous wavelength is greater than 380nm, it is called near ultraviolet LED, and it is called deep ultraviolet LED when it is shorter than 300nm. Semiconductor deep ultraviolet light source has great application value in lighting, sterilization, medical treatment, printing, biochemical detection, high-density information storage and secure communication.

Where are the difficulties? Because the luminous efficiency of ultraviolet LED is about half lower than that of using blue LED, brightness becomes a major topic of ultraviolet LED. The feasibility of using 400nm wavelength ultraviolet LED is being explored, because the wavelength of 380nm light will face the limit sooner or later in improving the luminous efficiency of white LED produced by ultraviolet LED.

Who is playing? In June, leader of global deep ultraviolet LED device and disinfectant system solution leader RayVio announced the realization of the optical power performance record of deep ultraviolet LED. Hongli optoelectronics is the only packaging enterprise that can produce deep ultraviolet LED in China. It has not only the large-scale production line of deep ultraviolet LED, but also set up its own professional microbiological testing laboratory, which is also the only one among the LED counterparts in China. Hongli optoelectronics has developed corresponding bactericidal solutions, working with well-known domestic water purification plants. Experiments confirmed that the use of Hongli photoelectric deep ultraviolet (UVC) LED, effectively inhibited the growth of bacteria in static water, with 99% bactericidal water purification effect.

4. Automotive lighting

What's fun? The advanced headlamp technology is no longer a simple lamp itself. It has developed into an intelligent technology combined with various electronic technologies. It not only provides energy saving and efficient lighting, but also greatly improves driving safety. The LED lamp lights up quickly, can reflect the vehicle condition and the road condition in real time, leave a longer judgement time for drivers, effectively prevent rear end collision, reduce vehicle safety accidents, and has positive significance for improving vehicle active safety.

Where are the difficulties? Hampered by high cost, LED will not be able to replace halogen and xenon lamps in the next 3-5 years. In the future, the price of LED headlights will decrease steadily, and will be more widely applied in the automotive field. LED headlights will also become more secure and intelligent.

Who is playing? Hongli optoelectronic LED automotive lighting business is developing rapidly, with an average annual growth rate of over 40%, and gross profit margin increased from 34.35% in 2011 to 44.25% in 2013. San an optoelectronic wholly-owned subsidiary of Wuhu Electric Co., Ltd., in July 17th, agreed with the Beiqi silver Xiang agreement. The company set up a branch in Chongqing to provide supporting services for Beiqi silver Xiang, producing auto lamps and LED products. Also in July, Ford developed a new generation of lighting systems that enable drivers to identify potential threats more quickly, including pedestrians, bicycles and animals on the roadside.

5, vehicle networking

What's fun? The Internet of vehicles is a huge interactive network composed of information about vehicle location, speed and route. Through GPS, RFID, sensor, camera image processing and other devices, vehicles can complete their own environment and state information collection; through Internet technology, all vehicles can converse their own information transmission to the central processing unit; through computer technology, the information of a large number of vehicles can be analyzed and processed. In order to calculate the best route of different vehicles, timely report road conditions and arrange signal cycle. The Internet of vehicles is one of the important signs of intelligent transportation and smart city.

Where are the difficulties? Most of the high-end sensors used for information collection are not controlled by Chinese companies. At the same time, the bottleneck of communication network bandwidth has also become a technical problem of vehicle networking.

Who is playing? Following the shareholding vehicle networking manufacturer Jiangsu South billion Dina technology 18% stake, Hongli photoelectric recently announced to buy Hui Tong 36.58% stake. Data show that Hui shtong has rich experience in the field of vehicle networking for ten years. It is one of the largest companies in China, which integrates R & D, production, sales and services to provide comprehensive vehicle operation services in the field of GPS, including taxi, bus, logistics vehicle, dangerous goods vehicle, etc. Car rental, long-distance passenger transport, private cars and other fields, and has entered the Shanghai Volkswagen and other pre loaded market.

6. Smart lighting

What's fun? The smart lighting system can automatically adjust the most comfortable color temperature and brightness according to human's psychological and physiological needs or the needs of the illuminated objects. By measuring information provided by sensing control, the intelligent lighting system will pick out the best visual or most suitable lighting for human physiology.

Where are the difficulties? Smart lighting is not as simple as adding intelligent programs to lighting devices, as it is generally supposed to be. It should be a product with perfect system, innovative technology and practicability. However, in the survey, we found that the intelligent lighting equipment sold in the market still has no breakthrough in technology, and it is only a conceptual product, and its practicability is not strong.

Who is playing? In 2012, PHILPS launched the Hue, which is a series of smart bulbs that can directly control the switch, brightness and color with mobile phones. People often see it in the apple retail store and put it together with expensive digital accessories. In the The Edge of the new headquarters building of Amsterdam New District, the sun is pouring directly from the auditor DDT in the new headquarters building of the New District of the city of Amsterdam. There are 6000 sets of intelligent LED Luminaires in PHILPS, which can not be directly covered by the sun.

7. Internet

What's fun? The role of the Internet is reflected in three aspects: first, the dissemination and popularization of Internet; two, the Internet of sales; and three, the Internet of public welfare practices. Based on the Internet, it is very scary to achieve large-scale and private customization through big data. "Internet +" LED has laid the foundation for customized and differentiated LED products, and there will be a blue ocean in the specialized segmentation market.

Where are the difficulties? The traditional LED industry is the foundation and the Internet is the end. However, with the Internet of supply chain, the concept between the end and the end is becoming more and more blurred, or even putting the cart before the horse. Intellectualization is undoubtedly a breakthrough for semiconductor lighting enterprises to break through in the era of "Internet +". Agriculture, optoelectronics, information technology and cross-border integration are very difficult, but the technical path can be explored.

Who is playing? Hebei Zhi Da photoelectric Polytron Technologies Inc innovated the application of "Internet +LED" technology to achieve energy saving of about 70%, and according to different needs of the "private custom" program, let the lighting equipment become "sensible" and "smart". In April, Shanghai Yi Yong Photoelectric Technology Co., Ltd. launched a new intelligent LED street lamp system, which realized LED street lamp on demand lighting, dynamic intelligent lighting, single lamp remote monitoring to achieve intelligent directional maintenance, instead of traditional manual inspection, and the charm of "Internet +" began to show in the lighting industry. And in the sales channel, LED e-commerce marketing mode is bringing traditional sales mode impact.

8, home furniture

What's fun? At present, the LED industry is progressively growing from maturity to maturity, and the scale of industry is further expanding. LED has accelerated its penetration to household lighting from landscape lighting, road lighting, commercial lighting and other fields. In terms of intelligence, intelligent lighting is the important content and requirement of smart home. In addition, there is a view that the integration of LED lighting lighting enterprises and Pan home will become a trend.

Where are the difficulties? When the popularity war is about to come in full swing, the price war is more and more volatile. LED enterprises have set off a price surge. LED lighting lighting enterprises and Pan home cross border integration is easy and difficult to talk about.

Who is playing? PHILPS and other international giants have been focusing on the home market. The United States focused on the field of LED chips, and has launched a product for the civilian market at the lighting exhibition this year. Similarly, the active layout of the civilian market includes traditional lighting giant Rex, OPPLE and FSL, among which FSL is the main market for the civilian market.

9, clothing materials

What's fun? Clothing and cloth are necessities of life. LED can be applied to clothing and fabrics to add new functions and aesthetic feeling.

Where are the difficulties? Clothes should be neither too bright nor too dim to feel beautiful. At the same time, we must hide the battery panels and switch devices, and pay attention to insulation to prevent short circuit discharge.
