Could Cree reps be providing incorrect data? (it’s complicated)
by John | Apr 3, 2014 | LED, optical engineering
Many of our LED optical design projects start with a simple calculation. Basically, we tell a client how much mechanical space they need to reserve for a lens to achieve the beam angle or pattern they want. In all cases, the larger the LED chip, the bigger the optic...
Why spot and beam uniformity are not always equal
by John | Jan 16, 2014 | LED, optics
For many LED optic projects, a spot size and beam angle can be specified with a single uniformity value. In cases of beam angles above 30 degrees, things get tricky. Please see the images below for an explanation. If you prefer to understand the math... Illuminance is...
