The RoHs-compliant QuasarBrite LEDs are available in three sizes: 4mm (provides beam angle of 12 to 22 degrees), 6mm (provides beam angles of 14 to 24 degrees), and 8mm (provides beam angle of 14 ...

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 ...

The ShineOn Dual Beam is presently the subject of a Kickstarter campaign, where a pledge of US$88 is required to get one. Assuming it reaches production, it should ship next March. The planned ...

Low beam headlights should light about 150 feet in front of the vehicle, so the angle depends on ride height. If the vehicle is lifted it must use a steeper angle. I have and easy way to check and ...

A high-efficiency beam steering angle expander consisting of two liquid crystal polymeric diffractive optical elements is demonstrated. For an LiDAR (light detection and ranging) operating at 905 ...
