| 摘要 |
The present invention relates to a high heat dissipation lamp including a base, a lower cover, and a substrate. The base is an empty structure and a first hole is defined inside the base. The lower cover is an empty structure disposed on the base and the second hole is defined inside the lower cover. The substrate is fixed between the base and the lower cover and has a first surface located toward the first hole and a second surface located toward the second hole. A plurality of light emitting diodes is disposed on the first surface. The first and second surfaces of the substrate are in direct contact with the first and second holes of the base and the lower cover so as to improve the performance of thermal convection. Also, the base and the lower cover of the lamp are in a ring shape so as to have a strong structure of the lamp and easily produce the lamp. |
