Abstract

An LED (light emitting diode) lamp includes a lamp body, a plurality of fixing assemblies fixed to a top of the lamp body and a plurality of fasteners fixed to the fixing assemblies. The lamp body comprises a housing defining a plurality of runners in a top thereof and a light emitting module mounted in a bottom of the housing and applying an LED module as a light source. The fixing assemblies are placed on the top of the housing. Each fastener has a head located at an underside of a corresponding one of the fixing assemblies and securely received in a corresponding runner. The fixing assemblies are provided for securely fixing the LED lamp in position and in a desired illuminating angle.

Claims

1. An LED (light emitting diode) lamp, comprising:

a lamp body comprising a housing defining a plurality of runners in a top thereof and a light emitting module mounted in a bottom of the housing and comprising an LED module as a light source;

a plurality of fixing assemblies placed on the top of the housing for fixing the LED lamp to a mounting structure at a selected illuminating angle, each of the fixing assemblies being moveable along a lengthwise direction of the housing by moving along the runners; and

a plurality of fasteners fixed to the fixing assemblies, each fastener having a bolt and a nut, the bolt having a head located at an underside of a corresponding one of the fixing assemblies and received in a corresponding runner and a shaft extending from the head through the corresponding one of the fixing assemblies, the nut being tightly screwed to the bolt and on a top of the corresponding one of the fixing assemblies to securely mount the corresponding one of the fixing assemblies to the housing;

wherein the housing comprises a heat spreader and a plurality of fins extending upwardly from a top surface of the heat spreader, a mounting part recessing inwardly from a bottom surface of the heat spreader and receiving the light emitting module therein;

wherein a plurality of fixing parts are formed on the spreader, each of the fixing parts comprising two fixing plates having different heights, an outer one of the fixing plates located adjacent to a lateral side of the heat spreader being higher than an inner one of the fixing plates, two locking plates extending inwardly and toward each other respectively from a top edge of the inner one of the fixing plates and an inner side of the outer one of the fixing plates, the locking plates level with each other and located above the fins, each runner being defined in a room surrounded by the locking plates and the fixing plates; and

further comprising a supporting plate extending inwardly from a top edge of the outer higher one of the fixing plates and located above the locking plate extending inwardly from the inner side of the outer one of the fixing plates.
