The QuasarBrite narrow-beam LEDs produce a tight beam of high-intensity red, green, or blue light from a surface-mount (SMT) package. Compared to traditional SMT LEDs, these narrow beam LEDs reduce ...
Following research at Sheffield-based LED packaging firm Litecool, narrow beam angles from LED packages without secondary optics or reflectors look closer. The proof-of-concept device produced a beam ...
For security surveillance, Osram has developed an infra-red (850nm) LED that does not need secondary optics. Instead it has an intrinsically narrow beam angle. “The Dragon Dome [SFH 4783] is the first ...
Incandescent lamps have almost vanished from many new avionics designs. Now high-efficiency light emitting diodes (LEDs), especially in white, have become inexpensive and readily available. LEDs are ...
The latest high-power silicon-based LED technology from Plessey Semiconductor is transforming form, function, and performance when it comes to luminaire design. Chip-on-board (COB) LEDs in a typical ...
