Led Beam
Pinpoint LED to replace a laser?
Does anyone know how to use a light (Led Light emitting diode) and the platform which emits a small beam as a laser would. I like to make it safe for children. Clearly, a laser can be dangerous Then I thought about using a LED. Ideas? Thank you
You can use a top (flat unlensed) LED and a lens convex to focus the light beam. You need an objective quality. Yet he never will get a bright spot like a laser beam.
