Abstract: An LED lamp includes a housing, a heat sink received in the housing, a plurality of LED modules thermally attached to the heat sink and a plurality of wire clips spanning over the heat sink and securing the heat sink on the housing. The heat sink includes a base and a plurality of fins extending from the base. Each of the clips includes a pivoting portion pivotally mounted on the housing, two locking portions located opposite to the pivoting portion and detachably engaging with the housing, and two pressing portions respectively interconnecting the pivoting portion with the two locking portions and abutting against the base.

Abstract: An LED lamp includes a bracket, two guiding plates and a number of LED assemblies. Each of the guiding plates includes a body, a top flange and a bottom flange extending from top and bottom edges of the body, respectively. The bottom flanges are mounted on opposite sides of the bracket. The top flanges are oriented towards each other. The LED assemblies are mounted to the bracket and sandwiched between the bodies of the guiding plates. The LED assemblies slide along a longitudinal direction of the guiding plates before the LED assemblies are assembled to the bracket by screwing the LED assemblies to the guiding plates. The quantity of the LED assemblies assembled to the bracket is selective thereby to meet different luminous density requirements/specifications.

Abstract: An LED lamp comprises an envelope, two heat sinks respectively disposed at two opposite ends of the envelope, two LED modules respectively received in the two heat sinks, and two light guide plates respectively mounted in the two heat sinks and over the LED modules. Each light guide plate is located at a light route of the LED module to reflect light emitting from the LED module into several light beams. The light beams are first emitted into a central hole of the envelope, spread on an interior of the envelope around the central hole and radiate out of the LED lamp from an exterior of the envelope. The central hole has a round shape, while the exterior has a triangular shape.
