Uniform angular light distribution from LEDs

A light source with improved angular light distribution comprising:

• a light emitting component which emits light of at least a first wavelength;
• a particulate light scattering material, which receives light emitted by the light emitting component and scatters the light of the first wavelength without appreciable absorption of the light;
• a phosphor material, which receives at least one of the light emitted by the light emitting component and the light scattered by the light scattering material, the phosphor material converting at least a portion of the received light to light of a different wavelength, at least a portion of the light of the first wavelength being unconverted by the phosphor material, wherein the light scattering material is in the form of a layer intermediate the light emitting component and the phosphor material.

A method of producing light having a more uniform angular color distribution, the method comprising:

• (a) scattering blue light emitted by a light emitting component, which emits light in the UV and blue regions of the spectrum, with a particulate light scattering material to increase the uniformity of the angular distribution of the light;
• and
• (b) converting at least a portion of the UV light emitted by the light emitting component to light of a different wavelength with a phosphor.
