Description

LED bulb heat radiation structure

Technical field

The utility model relates to the radiator structure of a kind of LED, especially a kind of radiator structure that uses the bulb of LED making.

Background technology

Because LED is with respect to existing light fixture, have many advantages like incandescent lamp, fluorescent lamp, electricity-saving lamp etc., energy-conservation, the life-span grows, do not have ultraviolet ray in environmental protection and the spectrum that produced, and infrared ray and radiation are typical green illuminations.The operating temperature of LED need be controlled at below 80 ℃ but the common problem that existing LED bulb exists is, the person is not burnt the life-span even moment of understanding serious shortening LED.Therefore have relatively high expectations for the heat dissipation design of LED bulb; Existing structure generally all is to adopt aluminium alloy to use the mode of die casting or extrusion modling to make the fin-shaped radiator of hollow; This structure manufacturing cost on the one hand is high; The control circuit of LED bulb is built in the radiator on the other hand, and this circuit may use high-tension electricity, and the entire heat dissipation body is charged to exist problem safe in utilization if the insulation system between control circuit and the radiator can cause when losing efficacy.

Summary of the invention

The purpose of the utility model provides a kind of LED bulb heat radiation structure, under the prerequisite that satisfies the heat radiation requirement, can significantly reduce manufacturing cost, and guarantees to keep between control circuit and the fin insulation to guarantee Electrical Safety.

The utility model is realized above-mentioned purpose through following technical scheme:

LED bulb heat radiation structure; Comprise bulb rack and be installed in the fin on the bulb rack; Said bulb rack is made by insulating materials; It comprises the Lamp cup part that is used to install the LED lamp body, and Lamp cup part below is provided with the cylinder of the hollow that is used for the installation and control circuit, and the cylinder below is provided with the lamp holder that is used to be electrically connected; Said fin contacts with LED lamp body radiator portion, and fin is provided with a plurality of heat radiation through holes that air circulates of being convenient to, and the bottom surface of Lamp cup part is provided with a plurality of openings that let fin penetrate radially, and fin is penetrated fixing by opening.

Wherein, said fin upper surface is provided with the flanging that contacts with the radiating surface of LED lamp body.

Wherein, the end face that said lamp holder is connected with cylinder is provided with a plurality of spliced eyes, and the bottom of fin is inserted in the spliced eye fixing.

Wherein, said fin integral body is triangular in shape, and hypotenuse is provided with the cosmetic sheet vertical with fin.

Wherein, said cylinder is connected through fastener with lamp holder to be fixed, and fastener comprises the buckle that is arranged at cylinder bottom interior wall flange and is fixed on lamp holder, and buckle and flange snapping are fixed.

Wherein, said cylinder outer wall is provided with the draw-in groove that cooperates with fin vertically.

The beneficial effect of the utility model is: bulb rack adopts insulating materials to make can guarantee maintenance insulation between control circuit and the fin, guarantee Electrical Safety that generally speaking insulating materials uses plastics to get final product, and can effectively reduce manufacturing cost like this.For guaranteeing radiating effect; A large amount of fin directly contacts with the radiator portion of LED lamp body; The heat that the LED lamp body is produced can be delivered on the fin; Fin distributes radially and is provided with a plurality of heat radiation through holes, can effectively increase air and between fin, circulate to take away more heat.Fin is installed through opening and bulb rack, and is simple in structure, easy for installation.
