HOUSING-RADIATOR OF THE LED LAMP Russian patent published in 2021 - IPC F21V29/74 

FIELD: lighting engineering.

SUBSTANCE: invention relates to lighting engineering, namely, to the design of the housing-radiator of a LED lamp and can be used in greenhouse crop production, as well as for lighting various rooms. The claimed heat-conducting housing-radiator of the LED lamp is made of separate longitudinal profiles 1 of solid section. In the middle of the inner side of the cross-section of the profile, a longitudinal rib 2 is made directed to the center of the cross-section of the radiator housing. On the outside of each profile, at least one led light source 3 is fixed. The profiles are connected to each other by connectors 4, so that planes of the outer surface of the profiles in the cross section of the housing form an equilateral polygon. Between the longitudinal edges 5 of the nearby profiles there are air gaps 6, the width of which, the "B" at the lower end and the “V” at the upper end is made with respect to the inequality B ≤ V.

EFFECT: technical result is increased efficiency of heat transfer from the inner surface of the radiator housing to the environment, which will reduce the weight and overall dimensions of the radiator housing, while maintaining the power of the lamp.
