摘要： The bulb with LED diodes is characterized in that the inlet channels (18) and outlet channels (19) of the cooling air are connected to one another through the air-tight arterial chamber (17) of the cooling air located between upper radiator's end (6) with plugged (blind) internal part (20), upper printed board (3) and parts of side printed boards (4) with LED diodes (5) protruding above the upper end of the radiator (6), connected air-tightly with elements elongating (2) the radiator's corner (6). Channels located between internal part of the radiator (6) and boards with inserts (9) directing the cooling air from the outlet channels (19) are blind. Outlet holes (13) of the cooling air are located directly under the collar (8) separating the radiator part (6) with the printed boards (4) with LED diodes (5) from the part of the radiator (6) with boards (7) directing the cooling air into the inlet channels (18), with boards with inserts (9) directing the cooling air from outlet channels (19) into the outlet holes (13). Lengths of elements elongating (2) the corners are equal to the parts of circuit printed boards (4) with LED diodes (5) protruding over the upper end of the radiator (6).
