LED LUMINAIRES FOR LARGE-SCALE ARCHITECTURAL ILLUMINATIONS Russian patent published in 2013 - IPC F21V29/00 

FIELD: electrical engineering.

SUBSTANCE: system contains the first illumination device (301) and the second illumination device (302), with the first gap (332) formed between them. Both the first and the second illumination devices contain multiple LEDs. The first illumination device generates radiation with a spectrum different from that of the second illumination device radiation. The rear surface of the first and the second illumination devices is thermally connected to heat dissipation structures. Placed inside the body (330) is a controller connected to the LED light sources and designed so that to enable control over intensity and the total perceived colour and/or colour temperature of radiation generated by the system. The controller body (330) forms the second gap (385) with the heat dissipation structures of the first and the second illumination devices, such gap connected to the first gap (332) to ensure ambient air flow passage through the illumination system.

EFFECT: enhanced reliability due to heat dissipation improvement and ensuring a wide spectrum of light effects at high density of heat flux.
