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 ...
Gem Hsin Electronics has announced new advances in its research and development of LED lighting products that enable wider beam angles competitors and uniformity of light. Gem Hsin has already started ...
MIT researchers have built a nanoscale photonic device shaped like a tiny ski jump that launches laser light directly off a ...
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 ...
The light intensity curves for LEDs, regardless of whether they are collimated with a lens or reflectors, follow a bell shaped curve (often referred to as a “Lambertian“ curve). The 50% intensity ...
Our test of 10 H4 halogen bulbs reveals that the high-beam reach of the worst bulb is 60 metres shorter than the best bulb tested. Worryingly, half of the bulbs didn’t meet the minimum required ...
