Lextar Announces Its 100-watt High Efficiency COB Products

Lextar Electronics Corp. announces its 100-watt COB LED products that have a high efficiency of 130 lm/W and low thermal resistance. In addition, Lextar’s Blue Emitter with HV chip as well as high color rendering light board (CRI>95, R9>90) will all be on display from June 9-12 at the Guangzhou International Lighting Exhibition.

The 100-watt COB LED product has a luminous efficiency of 130 lm/W and low thermal resistance of 0.5 degrees per watt, which is more than a 70% decrease compared with most LED products. This can help simplify the thermal structure of the lamp, lower costs, as well as provide a longer lifespan. These high-power COB products are suitable for streetlights and high/low bays. In addition, Lextar will showcase full COB series including 4, 6-8, 8-15, 15-25, 30-50 and 50-100-watt products, giving the LED industry a wide range of low-to high-powered options. Also, COB products have good uniformity, no multi-shadow, low thermal resistance, and simplified fixture design.

Lextar is also promoting its Blue Emitter with HV chip that can be used with remote phosphor. It can reach a good uniformity and customers can adjust the light distribution, color temperature and color rendering to their liking. These packaging products use Lextar’s own researched and manufactured HV chips, which can help with saving on electronics’ spare parts and space, and increase the flexibility in finished product design, especially for small sized lamps such as jewelry lamps and candle lamps.

Expect to see Lextar’s COB, PLCC and LED light module products at the lighting exhibition, all of which display Lextar’s craftsmanship in advanced lighting products from its vertical integrated business model.  Lextar has seen substantial results on the LED light module products that comes from its dedication on backlighting development for the past few years.  The company is to continuously develop high power and value-added COB accompanied by endorsements from global brands, to market in Europe and Japan.
