LED MODULE Russian patent published in 2013 - IPC H01L33/44 H01L33/50 

FIELD: physics.

SUBSTANCE: disclosed is a light source having a LED chip and a luminescent wavelength converter mounted side by side on a base. The LED chip is configured to emit excitation light in a first wavelength range, and the luminescent wavelength converter is configured to convert excitation light into converted light in a second wavelength range; a reflector with a built-in absorbing layer. The reflector is configured to transmit converted light from the luminescent wavelength converter, wherein the built-in absorbing layer is configured to reduce transmission by the reflector of any excitation light incident on the reflector at essentially oblique angles; and a separate hemispherical absorber, placed around the luminescent wavelength converter such that converted light from the luminescent wavelength converter passes through the separate hemispherical absorber at a normal angle of incidence, and excitation light transmitted through the reflector passes through the separate hemispherical absorber at an oblique angle. A light-emitting diode (LED) module is also disclosed.

EFFECT: simpler method of removing excitation light from light coming out of a source.
