Data Sheet ALMD-LG37, ALMD-LL37, ALMD-LM37, ALMD-LB37 High Brightness SMT Oval LED Lamps Amber, Red, Green, and Blue Description Features The Broadcom ALMD-Lx37 Oval LED series has the same Well-defined spatial radiation pattern or just slightly less luminous intensity than conventional High-brightness material high-brightness through holes LEDs. Available in Red, Amber, Green, and Blue colors Red AlInGaP 626 nm The new Oval LED lamps can be assembled using common Amber AlInGaP 590 nm SMT assembly processes and are compatible with industrial Green InGaN 525 nm reflow soldering processes. Blue InGaN 470 nm The LEDs are made with an advanced optical grade epoxy JEDEC MSL 2A for superior performance in outdoor sign applications. The Compatible with reflow soldering process surface mount Oval LEDs are specifically designed for full Tinted and diffused lens color / video signs and indoor or outdoor passenger Wide viewing angle: 40 100 information sign applications. Applications For easy pick-and-place assembly, the LEDs are shipped in Full color signs tape and reel. Every reeled is shipped from a single intensity Mono color signs and color bin except the red color for better uniformity. CAUTION InGaN devices are Class 1C HBM ESD sensitive, AlInGaP devices are Class 1B ESD sensitive per the JEDEC Standard. Observe appropriate precautions during handling and processing. Refer to Application Note AN-1142 for additional details. CAUTION Keep the LED in the moisture barrier bag (MBB) with <5% RH when not in use because prolonged exposure to environment might cause the leads to tarnish or rust, which might cause difficulties in soldering.

Dominant wavelength, , is derived from the CIE Chromaticity Diagram and represents the color of the lamp. d b. The luminous intensity is measured on the mechanical axis of the lamp package and it is tested with pulsing condition. c. The optical axis is closely aligned with the package mechanical axis. d. Tolerance for each bin limit is 15%. e. is the off-axis angle where the luminous intensity is half the on-axis intensity. Broadcom AV02-4541EN 2
