LED LAMP Russian patent published in 2016 - IPC F21V15/01 F21V29/74 F21V19/00 

FIELD: lighting engineering.

SUBSTANCE: invention relates to lighting engineering, namely, to design of general led lamps. Led lamp contains housing (1), coated with dielectric heat-conducting plastic; board with leds; diffuser (5), covering light-emitting diodes; power supply and base (7). Housing-radiator (1) includes two combined aluminium profiles (8), inner and outer surface of which is coated with dielectric heat-conducting plastic, outer wall has elongated ends (11) and flat surface section equipped with heat-removing cooling ribs (12), heat-removing ribs of the first part of the housing-radiator are oriented to the heat-removing ribs of the second part of the housing-radiator and mounted with gap (13); Board with leds is installed on flat surface sections of each aluminium profile; and elongated ends (11) of outer walls of each aluminium profile are connected to base (7) by means of dielectric heat-conducting plastic, recess (14) for power supply arrangement is made of plastic material, power supply is separated from the aluminium profile by air gap (15).

EFFECT: technical result is improved heat removal from leds and power supply, improved adaptability to manufacture and luminous efficacy of the lamp.
