FIELD: lighting equipment.
SUBSTANCE: invention relates to cooling devices characterized by passive heat-dissipating elements specially designed for lighting devices or systems, and can be used to ensure the thermal operation of emitting diodes and the formation of a radiation pattern of lighting devices based on them. The claimed lighting device with an emitting diode reflector-radiator, containing a plurality of emitting diodes located on the outer side of the surface of the printed circuit board, is equipped with fasteners on the outer side of the surface of the printed circuit board, each reflector-radiator is made in the form of a metal single unit with an arbitrary shape of the profile of the outer surface and contains a mirror optical system formed by the profile of the inner surface of the single unit. At the same time, a groove and fasteners are located on the interface surface of the mono-body with the printed circuit board section, connecting to the corresponding fasteners on the outer side of the printed circuit board surface.
EFFECT: increase in the efficiency of the device and simplification of its design.
