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 ...

I’m something of a headlight nerd. In a previous life, I retrofitted HID projector headlamps onto my 2009 Honda Civic Si for better light output. I’m planning a similar project for my beater 2015 VW ...

Maybe everyone else has known this for ages, but at last there is enough information on led and collimator data sheets to work out how far one should be form the other to get the specified beam. This ...

Everyone loves LED matrices, and even if you can’t find what you like commercially, it’s pretty easy to make just what you want. Need it big? No problem; just order a big PCB and some WS2812s. Need ...

Once it’s up to snuff, the sheet is immersed in a nickel bath, and galvanized. From there, it can serve as the master for mass replication. The researchers claim that the machine can produce fiber ...

LED Engin, a venture-backed California company offering high-power LED systems for specialty lighting applications, is set to become part of Osram, after the two parties agreed an acquisition deal.

Call us easily amused, but we think it’s pretty amazing what can be done with a microcontroller, some RGB LEDs, and a little bit of plastic. Case in point is [andrei.erdei]’s beautiful and quite ...

Design allows for system miniaturization and long-life solutions where previous technologies could not; also intended to replace mercury lamps. Japan-headquartered LED pioneer company Nichia has ...

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 ...
