Lextar to Showcase 4W-75W COB Lineup at Guangzhou Int’l Lighting Show

Lextar Electronics, a vertically-integrated LED company from Taiwan, will showcase its COB (Chip-on-Board) "Nimbus" series that feature high CRI (90), LM-80 quality and Hot Color Targeting (see note 1). The Company will also release Flip Chip COB : "Nimbus-P" series. Lextar has deployed the widest COB product line in the industry and it will debut this new COB collection at 2014 Guangzhou International Lighting Exhibition starting from June 9th in Guangzhou, China.

Lextar's COB "Nimbus" series, ranging from 4 watt to 75 watt, can be widely applied to various lighting applications including bulbs, spot lights, downlights, and bay lights. It delivers condensed light output without multi shadow, giving high quality light and making a good choice for commercial and professional lighting. Lextar's Nimbus offers three services, including high CRI, LM-80 high quality and Hot Color Targeting, to enhance added-value to its customers.

Lextar also debut its latest Flip Chip COB: Polaris (Nimbus-P) series, a new extension of Lextar's flip chip package for lighting application.  Nimbus-P series not only bears better over-drive capability but also intensifies product stability by using ceramic substrate. To add to that, it minimizes LES (light emitting area) therefore features high lumen density.  The LES can be reduced by 50% compared to that on conventional COB; hence this product is especially suitable for professional lighting where high brightness and concentrated lighting angle are necessary, such as PAR lamps and track lights.

"The launch of Nimbus-P has demonstrated Lextar's technology through its vertically integrated operation; it also delivers the excellence of Lextar's COB line," noted Francis Wong, Director of Lighting Business Unit of Lextar. The Company also provides customers a selection of COB including professional use, high quality and cost-effective models, as well as peripheral solutions that contain lenses, reflectors and holders supplied by global brands. Apart from the Nimbus COB series, Lextar will also debut various new products and technologies including high-voltage LEDs, AC-in DOB (Driver on Board), CSP (Chip Scale Package) module and so forth.  Lextar's GILE exhibition event site:

Note 1:  Normally LED fixtures operate at a high temperature of 85 degree Celsius. To help earn sufficient time for further product design and measurement for customers, Lextar offers "Hot Color Targeting" that provides the simulated data at the temperature of 85 degree.
