Challenge
An LED emits light in the form of a divergent bundle of rays. An additional lens within the LED housing is required to produce a less divergent cone of rays. What would an LED that emits perfectly collimated light, just like sunlight, look like?
Invention
The RES-LED features an internal reflector with convex, parabolic sides. After being reflected two or three times, the rays emitted by the LED become straight. A final refraction as they leave the housing then collimates them into an almost parallel bundle.
Advantages
- Artificial light source with the qualities of sunlight
- Collimation of the emitted light
- Modules containing several LEDs in one housing
Applications
- Artificial sun
- Headlights of all kinds
- Artificial light system for greenhouses
- Surgical light
