LED LAMP WITH HEAT-DISSIPATING BODY Russian patent published in 2021 - IPC F21S8/00 F21V29/00 

FIELD: lighting engineering.

SUBSTANCE: invention relates to the field of lighting engineering, namely to lighting devices for a fixed installation using semiconductors of point light sources (LEDs), and can be used in biotechnological systems of the "Synergotron" type for illumination of germinated plants. The claimed light-emitting diode lamp with a heat-dissipating body consists of a radiator body with linear printed circuit boards of a planar structure installed on it, with point light sources - LED chips. A thin-walled aluminum or copper pipe of rectangular cross-section is used as a body-radiator of a heat-dissipating body, made over the area of the luminaire in the form of a zigzag or a meander with pipe turns by 180° at the end of each long section of the luminaire, the inner space of which is filled with a flowing coolant-heat carrier, and in narrow longitudinal gaps between adjacent outer sections of the pipe in a zigzag there are fastening elements passing through the gaps and connecting LED boards with a metal substrate, power supplies with stabilizers and a board with control electronics, which are pressed against the heat-sensing plane of the zigzag on one side of the heat-sink housing of the board with heat-generating LEDs, and from the opposite plane, heat-generating power sources and a board with electronic control elements for the luminaire are fixed and pressed to the radiator housing.

EFFECT: increasing the intensity of heat removal from high-power LEDs, increasing the luminous efficiency of each LED, increasing the unit power of the LED luminaire, manufacturability and interchangeability of LED modules and blocks, as well as control electronics on the heat-dissipating body-radiator.
