Abstract:
An LED light source is described. The light source includes an LED and a diffuser. The LED emits a light having a dominant wavelength. The diffuser includes a filler material, which includes particles. The mean diameter of the particles is at least as large as the dominant wavelength of the light emitted by the LED. The particles are configured to scatter the light emitted by the LED.
