LED LAMP HAVING AN IMPROVED WATERPROOFING STRUCTURE
First Claim
1. An LED lamp comprising:
- a heat sink comprising a base and a plurality of fins extending from the base;
a plurality of LED modules each comprising a substrate plate thermally attached to the base of the heat sink and a plurality of LEDs mounted on the substrate plate;
a housing comprising a frame surrounding the base of the heat sink, and cooperating with the heat sink to define a first cavity between the frame and the base of the heat sink;
a first waterproof gasket being received in the first cavity and surrounding the base of the heat sink; and
a hood covering over the LEDs of the LED modules and contacting the frame of the housing.

Abstract
An LED lamp includes a heat sink, and a plurality of LED modules attached to the heat sink. The heat sink includes a base and a plurality of fins extending from the base. The LED modules each include a substrate plate thermally attached to the base of the heat sink and a plurality of LEDs mounted on the substrate plat. A housing includes a frame surrounding the base of the heat sink, and cooperates with the heat sink to define a first cavity between the frame and the base of the heat sink. A first waterproof gasket is received in the first cavity and surrounds the base of the heat sink. A hood covers over the LEDs of the LED modules and contacts the frame of the housing. A second cavity is defined among the hood, the frame of the housing and the body. A second waterproof gasket is received in the second cavity.
