Heat dissipation structure for LED lighting

摘要

A heat dissipation structure for LED lighting includes a light shade, at least one LED module, a wind guide member and a light seat. The light shade has a first opening and a second opening. The light shade further has at least one first extension section between the first and second openings. The LED module is inlaid in the first extension section. The light seat is connected with the light shade to form at least one perforation therebetween. The wind guide member serves to directly suck in airflow through the perforation to dissipate the heat generated by the LED module. The heat of the LED module is carried out of the first opening so as to lower the temperature of the LED module. Accordingly, the heat dissipation structure is free from any radiating fin assembly so that the total weight is reduced and the heat dissipation efficiency is enhanced.

主权项

1. A heat dissipation structure for LED lighting, comprising:
a light shade having at least one first opening at the top thereof and at least one second opening at the bottom thereof, the light shade further having at least one first extension section extending between the first and second openings to interconnect the first and second openings, the first extension section defining a passage; at least one LED module having a circuit board inlaid in the first extension section and partially positioned in the passage, and multiple LED chips disposed on the circuit board; a wind guide member disposed at the second opening, one side of the wind guide member facing the passage for blowing airflow to the circuit board in the passage; and a light seat, one end of the light seat being connected with the bottom of the light shade, at least one perforation being formed between the light seat and the light shade and in communication with the second opening.
