US 2018/0023796 A1 · LED LAMP

Abstract

A LED lamp includes LED modules. Each of the LED modules includes a heat sink body having a first terminal, a second terminal opposite to the first terminal, an airway having an opening at the second terminal, and a side hole on the side surface of the body. The side hole communicates with the corresponding airway. The LED modules are aligned to form concentric circles including an inner circle and an outer circle. The length between the first and the second terminals of each LED module at the inner circle is longer than that at the outer circle. Accordingly, heat generated by LEDs on the first terminals can be dissipated through the airways and the heat sink bodies.
