Ruifeng Optoelectronics newly pushes 7.5Lm high brightness white LED

For the lighting market, the advantages of LED Lighting applications are self-evident, especially in commercial, home, environmental decorative lighting, more energy-saving and environmental protection, zero noise pollution, zero ultraviolet radiation, zero strobe excellent characteristics.

Especially for the high luminous flux and high luminous efficiency requirements of the LED market, Ruifeng Optoelectronics recently introduced 3528 white TOP LEDs with a normal luminous current of 7.5Lm, which shows LEDs in fluorescent tubes, home lighting, commercial decorative lighting, etc. Application advantages.

The TOP View LED product with the product name WNRA30DS-FF is based on the traditional 3528 bracket specifications. Through process improvement and material improvement, it can be used under normal 20mA current. The luminous flux is up to 7.5Lm and the light extraction efficiency is up to 115Lm. /W. At present, all 8 spectral levels have been mass-produced. Please feel free to contact us for product details. 0755-29675000.
