Discussion Overview

The discussion focuses on designing a flashlight LED reflector lens aimed at achieving a flooding effect on the edges of the light beam. Participants explore potential tools and materials for lens design, as well as specifications for the lens size.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested, Experimental/applied

Main Points Raised

  • One participant is designing a flashlight with a new LED reflector that produces a good spot but seeks to enhance the flooding effect on the edges by creating a lens to disperse light.
  • Another participant inquires about affordable sources for lenses.
  • A participant specifies that the lens diameter needs to be approximately 2 inches.
  • A suggestion is made to use software tools like TracePro or LightTools for lens design.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the best tools or sources for the lens, and multiple suggestions and inquiries remain unresolved.

Contextual Notes

Limitations include the lack of specific details on the desired lens shape or material, as well as the absence of information regarding the performance characteristics of the proposed tools.

I'm designing a flashlight using a new LED reflector. It creates a good spot, but I want it to flood on the edges. See image below. My thought was to create a lens and put it in front of the LED reflector to disperse the light around the edges. Can anyone point me to some simple tools that will help me design the lens?

Thanks George. Where can I get cheap lens?
 
I'm in Atlanta. The lens needs to be about 2" in dia.
