Infrared LEDS

Product Feature:

Luminus offers infrared LEDs at 730nm, 850nm and 940nm. Our IR SST family comes in two different beam angles 90-degree and 130-degree and are specifically designed to handle the high pulse currents used in most infrared applications.

產品特點及優勢UVA 365nm – 415nm適合不同應用的封裝設計更高電流驅動能力提供DLP匹配用UV光源


Product Feature:

From touch screens to mobile phones to labels on bottles of water, UV LEDs have revolutionized how objects get cured—instant on, no VOCs and long lifetimes are some of their advantages. UV Curing whether printing, coating or adhesives requires maximizing intensity to increase throughput. Luminus engineers its LEDs to be driven at ultra-high current densities to maximize W/cm2 in curing systems. Our wide range of 365-405nm products, from die to lensed and un-lensed packages and with 1-30 W of UV power, enable modular and scalable designs for spot, line and array curing applications.
