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 ...
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 ...
Gem Hsin Electronics announces new advances in their research and development of LED lighting products that enable wider beam angles competitors and uniformity of light. Gem Hsin Electronics has ...
Just buy one with the right beam angle, and you are off. Right? Well maybe, but probably not. Because there are a few more things to think about before you can be pretty sure that what you buy will do ...
The CoveWash linear LED lighting system provides even illumination with user-specifiable beam angles. It is intended for cove (recessed) and other indirect indoor lighting applications in commercial ...
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 ...
