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 ...
Ordinarily, headlamp users have to manually switch the angle of their device, depending on what they're doing. The Adaptev Headlamp isn't like that, in that it automatically switches beam angles based ...
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 ...
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 ...
Yet again, I was asleep when an innovative optic first appeared. This one is a TIR collimator inside a collimator, intended to get fairly narrow beams from CoBs. Sized for fitting in PAR20s and called ...
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 ...

MIT photonic ‘ski jumps’ beam laser light off chips for quantum
MIT researchers have built a nanoscale photonic device shaped like a tiny ski jump that launches laser light directly off a ...
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 ...
