Patent attributes
A heat dissipation structure for LED lighting includes a light seat, a support body, a cap body and a lens. A heat sink and a fan are assembled on the support body and disposed in the opening of the light seat. The cap body has a first open end and a second open end. At least one air outlet is formed on the cap body in adjacency to the first open end. At least one air inlet is formed on the cap body at the second open end. The fan serves to forcedly drive airflow from the air inlet into the light seat and then drive the airflow to multiple radiating fins of the heat sink so as to directly carry the heat from the radiating fins to outer side through the air outlet. Accordingly, the heat dissipation effect is enhanced and the noise is reduced.
