Company Information
Alight Optoelectronic Industry Commerce Co., Ltd. founded in 2001, located in Xiaolan Town , Zhongshan City, Guangdong Province. It is earliest LED encapsulate factory in Zhongshan City.
In 2007, we cooperated with Semiconductor Research 13th Institute of China Electronics Technology Group and begin the research on new LED light panel encapsulate technology.
Since 2008, we adopted our patent Chip-on-Board encapsulation LED panels in industrial and commercial illumination field. We R&D successfully different types of COB LED lamps to replace traditional incandescent bulb,fluorescent lamp, compact fluorescent energy-saving lamp, high voltage sodium lamp etc.
In the future, we will continue to leverage the support from the Semiconductor Research 13th Institute, innovative products and with COB panel as the light sources, continue research and develop high efficiency, energy-saving, high quality and low price LED semiconductor lighting products, devote ourselves to Green Earth.
FAQ
1. What is AC COB LED? The AC COB LED is directly driven by the mains power supply 220VAC or 120VAC, meaning that no additional drivers are required and are illuminated directly by the AC110V or AC220V.
2. What is DOB? DOB is the abbreviation of the driver on the board. It is equal to AC COB.
3. What is the advantages of AC COB LED? -It is well known that the drive is the most vulnerable part of a luminaire, This is mainly limited by the short life of electrolytic capacitors. We have solved this problem in a completely new way. Integrate key components into the COB and avoid to use electrolytic capacitors.
4. Does the AC COB LED module flicker free? - LED strobe is caused by the use of poor quality driver. The AC COB LED module developed by our company solve this problem by using proprietary technology. Flicker free outside 50CM, suit all lamps except table lamps, such as ceiling spotlights, downlights, street lights, floodlight, track lights and so on.
5. Is the AC COB LED module dimmable? -Our AC COB LED module suit most dimmers on the market, such as DALI dimmer, 0-10V dimmer, 1-10V dimmer, triac dimmer and so on.
