RPC Photonics' optical diffusers offer unparalleled beam shaping capabilities for solid-state lighting applications. We not only homogenize LED illumination but we shape and distribute it to maximize light utilization and efficacy.
Here are some of the benefits of Engineered Diffusers™ for LED applications:
High efficiency (over 90% transmission without AR coatings)
Performance independent of wavelength
Highly homogenous, uniform light distribution
Efficient distribution of light (only where needed)
The picture below shows the lack of uniformity for an LED source collimated to about ±5-degree.
Non-uniform light from a nearly-collimated LED source
An LED LightShaper™ is an optical diffuser that not only homogenizes the LED source eliminating non-uniformity but generates a uniform light distribution, instead of the Gaussian distribution typical of common diffusers, such as ground glass or holographic diffusers.
Uniform light distribution from red LED
Uniform ligtht distribution from blue LED
Uniform light distribution from white LED
Uniform light distribution from green LED
But effective homogenization is only part of what our LED LightShapers™ can do.
Some lighting applications such as
Architectural
Entertainment
Medical
require arbitrary light distributions to create unusual effects or to simply avoid loss and light pollution.
Our LED LightShapers™ are true beam shapers with capabilities that go far beyond simple light diffusion. Take a look at our LED LightShapers™ Gallery.
