COMBINED LIGHT FIXTURE Russian patent published in 2014 - IPC F21S2/00 

FIELD: electricity.

SUBSTANCE: invention is related to light fixtures combining discharge lamps and powerful light-emitting diodes used for general lighting and ray treatment in crop growing. The light fixture contains fittings with a discharge lamp, in particular, with a high-pressure sodium lamp (HPS) or a metal-halide lamp (MHL) installed axially in the elongated concave reflector, powerful light-emitting diodes, starter and regulator devices and supply devices on top of them. One or two flat end walls of the reflector are mounted under the sharp angle towards the outlet of the lighting fixture and made as a cascade of transversal steps of heat-conductive material in the reflector while light-emitting-diode (LED) modules, LED lines or separate LEDs mounted on these steps in the heat contact zone emit in the selected spectral ranges adding to emission of the discharge lamp and changing the total spectral distribution.

EFFECT: decrease in dimensions with simultaneous potential formation of light spectral distribution.
