The HLCP-X100 and HLMP-2XXXseries light bars are rectangular light sources designed for avariety of applications where a large bright source of light is required. These light bars are configured in single-in-line and dual-in-line packages that contain either single or segmented light emitting areas. The Alga As Red HLCP-X100 series LEDs use double heterojunction Alga As on a Ga As substrate. The HERHLMP-2300/2600 and Yellow HLMP-2400/2700 series LED shave their p-n junctions diffused into a Ga Asp epitaxial layer on a Gap substrate. The Green HLMP2500/2800 series LEDs use aliquid phase GaP epitaxial layer on a GaP substrate. The bicolorHLMP-2900 series use a combination of HER/Yellow orHER/Green LEDs.
