Abstract

The utility model provides a heat radiating structure for lamps. A heat radiating piece is matched outside the lampshade and a plurality of heat conducting rods pass through the lampshade and then contact with the LED light panel in the lampshade and the heat radiating piece outside the lampshade. The excellent heat conducting characteristic and the physical contact conduction of the heat conducting rods will conduct the heat energy given off by the luminescence of the LED light panel at real time to the heat radiating piece with a lower temperature, while the temperature of the heat radiating piece is further reduced by means of the ventilation and radiation outside the lamp and then the heat conducting rods can continue to conduct the heat energy to the parts with a lower temperature so as to elevate the lamp heat radiating efficiency, to solve the problems that the lamp is easily damaged due to the accumulation of heat as the existing LED lamp is ill-natured in heat radiation and to prolong the service life of LED lamp.

The specific embodiment

For making lamp cooling structure of the present utility model clearer and more definite, below will be described in more detail with graphic cooperation embodiment.

See also Fig. 1 and Fig. 2, the utility model lamp cooling structure comprises a lampshade 1, an euphotic cover 2, a LED tabula rasa 3, a radiating piece 4 and a plurality of heat conduction screw rod 5.

This lampshade 1, by this lampshade 1 outside moulding one circuit pipe 11, for the link tester mistake, and assembly is in lamp stand from its inner surface, and this circuit pipe 11 is in these lampshade 1 edge shaping two pivot ears 12 relatively.

These euphotic cover 2, one ora terminalis two pivot ears 21 that are shaped with the pivot ear 12 corresponding configurations of its pivot ear 21 with this lampshade 1, by the pivot ear 12 of this lampshade 1 and the pivot ear 21 of this euphotic cover 2, are hubbed at this lampshade 1 with euphotic cover 2 with a pivot 22.

This LED tabula rasa 3 is equipped between this lampshade 1 and this euphotic cover 2, and this LED tabula rasa 3 comprises a radiating piece 31, a plurality of pedestal 32 and a plurality of LED33 that is equipped on these pedestal 32 surfaces.This radiating piece 31, be to be fixedly arranged in this lampshade 1, it comprises a heat sink 311 and a plurality of radiating fin 312, this pedestal 32 of being furnished with LED33 is provided in heat sink 311 lower surfaces of this radiating piece 31 towards this euphotic cover 2, and heat sink 311 upper surfaces of this radiating piece 31 are radiating fins 312 of uniformly-spaced moulding plurality of parallel.

This radiating piece 4 is fixedly arranged on this lampshade 1, its comprise one with the heat sink 41 of this lampshade 1 by establishing, and in the radiating fin 42 of this heat sink 41 first-class interval moulding plurality of parallel arrangements.
