December 10, 2011 High-tech LED Conference - Technology Preview Theme V: Technology Preview: "LED Lighting Design", Theme VI: Technology Preview: "Standard and Testing Certification" and Theme VII: Technology Preview: "Drive Technology" Session Held in the Multi-functional Conference Hall of Qingqing World. At the meeting, technical experts in the domestic LED field interpreted the standard testing and certification, and shared technical achievements and development trends for driving technology and power supply design.
Huizhou Hui Yuan Optical Co., Ltd. Deputy General Manager Shiyu speech to the mall public spaces LED lighting solutions. Firstly, the characteristics of the demand for shopping mall lighting were analyzed. From the basic purpose of the lighting of the shopping mall, the illumination standard and the performance method, the advantages of LED in the lighting of the shopping mall were obtained.
He believes that with the rapid development of LED lighting technology, its advantages in terms of "light efficiency, longevity, lighting quality" are more and more obvious, and its comprehensive performance is unmatched by any previous light source. Therefore, the design of LED lamps for shopping malls will inevitably put forward higher requirements. For example, rich light distribution, stable light output, various mounting forms, and various functional accessories.
Guangzhou STSP Integrated Electronics Co., Ltd., chairman of the lecture, Dr. Wu Weiguo into power LED light and LED lighting design in two parts. He introduced a waterproof, dustproof and high-power LED light power supply assembly that combines light source, power supply, heat dissipation and light distribution, which is simple, light and power-saving, and the street lamp and industrial and mining lamp which are derived from this. Structural design of downlights and bulbs. In the speech, the design schematic diagram and practical application of the LED driving circuit, the high-power light source production technology, and the heat dissipation method combined with the traditional conduction heat dissipation and the forced cooling of the fan are analyzed in detail.
Shenzhen-Lighting Co., Ltd. Deputy General Manager Xu Jiangang share for new thinking LED bulb design and participant. He believes that it is recommended to design 9W LED bulbs in terms of marketing, making consumers more intuitive comparisons, and unifying standards. In the future, 5W LED bulbs will be the trend. Future design trends should evolve from diversification, integration, specialization, and intelligence.
Finally, according to Haitz's law, LED brightness can be doubled every 18-24 months. That is, 2011: 810 lm / 9W = 90 lm / W, 2013: 810 lm / 5W = 190 lm / W 2015: 810 lm / 3W = 270 lm / w.
Gao Kewei , technical director of Hangzhou Hangke Photoelectric Co., Ltd. introduced the technical characteristics and difficulties of the COB surface light source for LED fluorescent lamps, and made a detailed comparison between the COB package and the traditional LED package.
He introduced that the COB surface light source is even and soft without glare, effectively avoiding the disadvantages such as spot light and glare in the combination of discrete light source devices. The LED fluorescent lamp uses a flat design of the COB surface light source to shorten the optical path, increase the light extraction rate, and also reduce the colloid temperature and slow down the gel aging. However, COB packages still have shortcomings such as light decay, brightness, and spot uniformity. The COB package of large chips still has many problems such as thermal resistance and light efficiency. In addition, COB light sources still have standardization problems, leading to packaging manufacturers and lighting finished products factories. The standard cannot be docked.

There are plenty of benefits for using usb type c cable For starters, the port is reversible! But that is only the tip of the cable. And like ice bergs, there is much more than meets the eye in type c cables. They allow for faster transfers, charging, 4K monitor output and more.
Needless to say we will have to start populating our living spaces with USB 3.1 Type C and accessories.It measures in at 1.8 meters of length and can handle USB 2.0 charging, as well as up to 60W of fast charging power. Not bad at all.
