Everlight’s recent announcement of its Low/Mid Power LED series is directed towards light bar and replacement omni directional bulb applications. This series consists of 0.06 W, 0.2 W, 0.4 W, and 0.5 W products with efficiencies of >100 lm/W. These LEDs are of different form factors; 3020 and 3528 (0.06 W), 5050 (0.2 W), and 5630 (0.4 W and 0.5 W) package sizes.

The 3020 and 3528 (0.06 W) packages are ideal for light bar applications. Many of these small packages can be densely packed onto a linear heat sink to provide the required light uniformity of linear solutions. As a result, a linear LED light bar can emulate the appearance of traditional fluorescent tubes. In addition, because these are small, low power LEDs, the minimal thermal dissipation of linear fixtures is sufficient in maintaining a low substrate temperature as well as a low junction temperature within the LED, resulting in better performance and lifetime. To increase the advantage of using low power LEDs and improve overall light quality in the fixtures, Everlight can offer 200 mcd/bin for intensity uniformity and 0.1 V/bin for more consistent electrical design.

The most recent market trend and direction for the general lighting market is towards cost conscious, consumer price acceptable replacement A-bulbs. It is predicted that 257 million A-bulbs will be sold worldwide in 2013. With current price and performance pressures, the Mid Power 5630 (0.4 W and 0.5 W) package is aggressively surpassing traditional COB and high power LED light sources as the preferred package type for A-bulb applications. 5630 packages have superb Lm/$. This is derived from the combined resources of the backlighting and the general lighting market. This shared capacity results in stable quality and commercial competitiveness over other types of LEDs. In addition, the balance of lumens output, power consumption, and package size allow the 5630 to optimally spread light and heat by spatially distributing the LEDs uniformly in the dimensional confines of an A-bulb.

All Everlight Low/Mid Power LEDs follow ANSI binning, have a wide range of CRI values, and are undergoing LM80 testing. The flexibility of Everlight Low / Mid power LED in packaging, binning and chip selection gives engineers more options in creating unique lighting fixtures with acceptable prices.
