LIGHT-EMITTING MODULE, LAMP, LIGHTING DEVICE AND DISPLAY DEVICE Russian patent published in 2016 - IPC H01L33/60 

FIELD: electronics.

SUBSTANCE: light-emitting module 150 emits light through light conductive window 104 and comprises base 110, solid-state light emitter 154, 156, and partially diffusely-reflecting layer 102. Base 110 has light-reflecting surface 112, which faces to direction of light conductive window 104. Light-reflecting surface 112 has reflection factor of base Rbase, which is determined by ratio between quantity of light, which is reflected by light-reflecting surface, and quantity of light that falls upon light-reflecting surface. Solid-state light emitter 154, 156 emits light of first colour range 114, comprises top surface 152, 158, and has coefficient of reflection R_SSL of solid-state light emitter, which is determined by ratio between quantity of light, which is reflected by solid-state radiation source 154, 156, and quantity of light that falls upon top surface 152, 158 of solid-state light emitter 154, 156. Light conductive window 104 contains at least portion of partially diffusely-reflecting layer 102.

EFFECT: relatively efficient light-emitting module is provided in case when value of effective reflection coefficient Reff > R_SSL + c* (1-R_SSL), and multiplier c is equal to 4/10 ≤ c ≤ 1 at ρ_SSL > 25/100.
