LIGHT-EMITTING DEVICE Russian patent published in 2017 - IPC F21V3/04 F21K9/62 F21V9/16 

FIELD: lighting.

SUBSTANCE: light emitting device (100) is proposed. It comprises a solid-state light source (101, 201) configured to emit primary light. The light emitting device also comprises a wavelength-converting element (105, 205) configured to receive the said primary light and capable of converting the said primary light to secondary light. Moreover, the wavelength-converting element and the solid-state light source are mutually spaced. Also, the light emitting device comprises a non-absorbing, partially transparent reflector (106, 206) located on the light output side of the wavelength-converting element to prevent visibility outside the wavelength-converting element colour, when the light-emitting device is off. At that, the primary light emitted by the solid-state light source and the secondary light formed by the wavelength-converting element can be transmitted by a non-absorbing, partially transparent reflector to exit the light-emitting device. Moreover, the non-absorbing partially transparent reflector has the same light reflection coefficient in the wavelength range of 400 nm to 800 nm. A lamp and a lighting fixture are also provided, comprising the light-emitting devices described above.

EFFECT: improvement of the device.
