Detailed description of the invention
For further setting forth the utility model for the technological means reaching predetermined goal of the invention and take and effect, below in conjunction with accompanying drawing and preferred embodiment, to according to heat radiator dedicated detailed description of the invention, structure, feature and the effect thereof of a kind of LED lamp that the utility model proposes, be described in detail as follows.
Refer to Fig. 1, be the heat radiator dedicated exploded perspective view of LED lamp of the present utility model, it comprises: LED-baseplate 1, substrate stage 2, heat conduction core 3 and radiation shell 4.
LED-baseplate 1, it is provided with lamp pearl, LED-baseplate 1 is bonded with heat-conducting glue and uses screw fastening in substrate stage 2.
Substrate stage 2, refers to shown in Fig. 2, and it is fitted tightly by the heat-conducting plastic disk of periphery form around the heat conduction core 3 of inside.Be used for carrying LED-baseplate 1, and absorb the heat of LED-baseplate 1.
