Heat dissipation structure based on LED corn lamp

Abstract

The invention discloses a heat dissipation structure based on an LED corn lamp. The heat dissipation structure comprises a base, a plurality of fixing ribs integrally arranged on the edge of the lower end surface of the base and an annular driving power bin formed in the middle of the lower end surface of the base. Slots are formed in the left side wall and the right side wall of each fixing rib, and a strip-shaped lamp panel is fixed between every two adjacent fixing ribs through the slots. The base is provided with a plurality of upper ventilation holes, and a round lamp panel is fixed under the fixing ribs through an end cover and is provided with a plurality of lower ventilation holes. According to the heat dissipation structure, the base is provided with the upper ventilation holes, the round lamp panel is provided with the lower ventilation holes, and therefore convection of heated air inside an LED corn lamp shell can be realized, hot air generated by exchanging heat with the lamp panels can be discharged from the LED shell faster, the heat dissipation requirement can be completely met through the heat dissipation structure for the LED corn lamp, the LED corn lamp is good in heat dissipation effect, and the manufacturing cost of the LED corn lamp is lowered.

Description

technical field [0001] The invention relates to a heat dissipation structure, in particular to a heat dissipation structure based on an LED corn lamp. Background technique [0002] With the promotion and development of LED lighting products, low-cost, high-quality LED lighting products have become a new development trend. Driven by this trend, LED corn lights with plastic shells are gradually entering the market, but the plastic shell is heat-conducting. Poor, and the structure of the shell is not designed with a heat dissipation structure, so the LED corn lights with plastic shells on the market now need to install a heat sink between the shell and the light board, and some heat sinks are not effective, not only The production cost of LED corn lights is increased, and the product quality of LED corn lights is not guaranteed. For example, the light decay time of the light panel of LED corn lights is likely to be greatly shortened, and the service life of LED corn lights is a...
