COMBINED LIGHT FIXTURE Russian patent published in 2014 - IPC F21S8/00 

FIELD: electricity.

SUBSTANCE: invention relates to electric engineering and it can be used for lighting of highways and in plant breeding. Combined light fixture contains lighting fittings with high-pressure discharge sodium lamp or metal-halide lamp installed in concave reflector, to which side walls LED elements are adjoined providing thermal contact at cooling radiators; LED elements are made in the form of matrix, lines or modules with powerful LEDs having optical axes oriented in parallel or at sharp angle towards the main focal plane of reflector. Emission of LEDs is made in the selected spectral ranges supplementing emission of gas discharge lamp and changing the total spectral distribution of the light fixture. LED elements are pivotally connected in the fittings; slope angle of their optical axes can be changed towards focal plane of the reflector and they are heat insulated from side walls by air gap.

EFFECT: optimisation of spectral distribution for the light fixture and improving heat removal.
