In recent years, the LED lighting industry has developed intelligent, diversified and high-end development trends, and a series of new trends have brought new opportunities and challenges to Shanghai. Cultivating Shanghai's LED innovation capability has become an important part of Shanghai's construction technology innovation center.
Shanghai is one of the earliest four national semiconductor lighting industrialization bases in China. It has a solid technology and industrial base, and its annual output value continues to grow at a rate of more than 10%. At present, Shanghai's industrial development has basically formed an industrial structure dominated by high-end technology, high-end applications and high-end services, and has penetrated into various cross-cutting fields, and has made good progress in the fields of automobile, agriculture, medicine, and intelligent lighting.
Zhangjiang is the core area of ​​the National Semiconductor Lighting Shanghai Industrialization Base, which is home to all of Shanghai's high-end LED equipment companies. Shanghai LED industry features high-end equipment, high-end technology and application innovation, and has become a technological highland in the country.
LED vehicle networking applications and technical services in the field of the future of driverless cars <br> <br> engineers have been trying to make driving more intelligent and more secure. To this end, they proposed various programs: laser, radar, ultrasonic, point-to-point WiFi, advanced image recognition technology. But these solutions are very complicated and expensive to apply, but maybe the solution is simple, just add LED lights to the car. The visible light emitted by the LED can create a cheap car network. The car originally has a headlight and a taillight, so as long as this mechanism is introduced into the new system, the communication between the vehicles can be formed by using the optical communication (LIFI) to create an LED smart car. Lighting communication system. It can cover traffic conditions, location, collisions, etc. These messages can be transmitted between vehicles by high-frequency flashing of LED light. The technology was released by the Shanghai Institute of Microelectronics, Peking University, and the future application direction will focus on the auto-driving system.
Access to the Internet on the plane, an indoor space can be positioned <br> <br> operation of aircraft can not communicate, the Internet has been a problem for the industry, EMI conventional wireless communication would threaten the safety of aircraft, causing the aircraft became cut off from the outside world closed Space, but this bottleneck will be completely broken in the future. The visible light communication (LIFI) product released by the China Aerospace Science and Technology Corporation, Inc., No. VIII, uses electrical signals to control the high-speed flickering signals from the light-emitting diodes (LEDs) that are invisible to the naked eye to transmit information. As long as a tiny chip is implanted on the bulb, it can become a device similar to an AP (WiFi hotspot), allowing the terminal to access the network at any time. At present, two LIFI optical communication equipments successfully developed, one with a high speed of 150Mbps, have the characteristics of no electromagnetic interference and high confidentiality, and can be applied to radio-sensitive occasions such as airplanes and operating rooms. The other is low speed 10Kbps, suitable for indoor positioning, shopping mall advertising, intelligent transportation, photon access control and so on. At present, the positioning equipment on the market has certain limitations, and closed places such as indoors and tunnels cannot be accurately positioned. With the fixed fixture position and LIFI technology, the precise location can be determined in large supermarkets, shopping malls and tunnels, so that the positioning can be fully covered.
LED intelligent control system will become an invisible "housekeeper"
Still envious of all kinds of sophisticated intelligent equipment in the Bill Gates mansion? Now this is not a dream, it has actually entered our daily life, when you go home at night to open the door, the integrated lighting equipment LED lights are turned on, At the same time, the music is sent to the Qingyang music to soothe the fatigue of the day; when the party is at home, the lights are automatically adjusted to become warm white, which brings a warm atmosphere of gathering; when the reading work is automatically adjusted to cool white light, the environment is more suitable for meditation. Now realized by sensors and LED lamps, the intelligent control system of LEDs released by Shanghai Jiu Gao Energy Saving Technology Co., Ltd. can perfectly realize the functions of dimming and coloring, flexible setting, group management, status inquiry and fault alarm of lighting fixtures. More user-friendly to meet the requirements of users, to maximize energy savings. The semiconductor device characteristics of LEDs have absolute advantages in intelligent lighting control. The combination of processors, sensing technology, wireless control technology, system integration and other multi-field technologies is a topic of high technical level and development space. It is the direction of future industrial development.
Domestic high-end chips let LED lamps have China's "core"
At present, in the international chip market, major manufacturers are competing on LED flip chip. Flip chip will grow rapidly on the basis of US$1.5 billion in 2013 and will reach US$5.5 billion in 2017. The inverted chip developed by Yingrui Company uses advanced laser stripping technology to separate the sapphire substrate and transfer the epitaxial onto the Si substrate with good conductivity and thermal conductivity. The micro/nano surface roughening effectively improves the light extraction rate; The current expansion technology optimizes the current expansion to ensure the reliability of the chip, so that the product has the strength to compete with international brand chips such as Nichia and Samsung.
The Aurora Light High Power Chip is completely developed by the domestic company. The 1ALED illumination stage high drive current flip chip can achieve 310 lumens under 1A current drive and 230 lumens per watt under 700ma current drive. It has low thermal resistance and excellent over current. Driven, high reliability, easy secondary optical design and other advantages. According to public information, the corresponding data of the Philips chip of the same specification is 300 lumens and 220 lumens. The corresponding data of the US Cree is 297 lumens and 223 lumens. The optical performance of the Northern Light Optical chip has been world-leading. The advent of this product broke the technological monopoly of chip giants Philips and Nichia, and its performance surpassed that of international giants such as Nichia and Philips.
