Wanbang photoelectric 7-watt bulb lamp won the first prize of the lighting competition with 3000 hours zero attenuation

On July 11th, the 4th IEEE Lighting Lighting Recommended Product Competition (hereinafter referred to as the Contest) awarding ceremony was held in Shanghai, which also indicates that the comprehensive evaluation of national excellent products that took half a year has come to an end. Wanbang Optoelectronics sent the inspection 7 The tile bulb was finally harvested with a 3000-hour zero attenuation.

At the end of last year, the competition sponsored by Shanghai Semiconductor Engineering Technology Research Center, National Optical Power Quality Supervision and Inspection Center (Shanghai) and other units covered the excellent products of almost all well-known domestic manufacturers, and carried out rigorous tests in a pragmatic manner. Safety, photoelectric parameters, electromagnetic interference, 3000 hours of attenuation, etc., can be considered a full range of tests. This evaluation was initiated by a third party in China, authoritative, fair and just, and the release of data, which played a guiding role for consumers to choose LED lamps.

The LK-7W produced by Wanbang Optoelectronics adopts the self-developed MCOB light source. The light source adopts a unique technical route, the direct-attachment heat-dissipation process and the self-developed BOSS primer, so that the heat can be dissipated at the shortest speed. Guaranteed the possibility of zero-zero attenuation in this 3000 hours, this technical indicator is far ahead of other products tested this time; and the light efficiency of this test is 132.6LM/W, which is 83.4, which is also internationally similar. The highest indicator of the product, all indicators are in line with the relevant national testing standards.


It is understood that the company has recently developed the fifth generation of radiant porcelain technology, and has made a huge breakthrough, the overall lighting efficiency has exceeded 170LM / W.
