Abstract: An LED lamp assembly includes a bracket, a heat sink secured on the bracket, a plurality of LED modules mounted on a bottom of the heat sink, and a transparent envelope correspondingly covering the LED modules. A sealing chamber is cooperatively defined by the heat sink, the bracket and the envelope, and the LED modules are received in the sealing chamber. The LED assembly is further provided with a gas-injecting member for injecting a predetermined gas into the sealing chamber of the LED lamp assembly therethrough.

Abstract: An LED lamp includes a base plate, a plurality of LED components fixed on the base plate in lines and a light-guiding module located over the LED components. The light-guiding module has a plurality of light-reflecting bars mounted above the LED components. Each of the light-guiding bars is in alignment with a line of the LED components and has a thickness gradually decreasing toward the line of the LED components.

Abstract: An LED lamp includes a bracket, a heat sink mounted on a top side of the bracket, and a plurality of LED modules mounted on the heat sink. The heat sink includes a base and a plurality of mounting members extending downwardly from a bottom surface of the base. Each of the mounting members includes an extending plate formed on the bottom surface of the base and a mounting plate extending slantwise upwardly and outwardly at a bottom end of the extending plate. The LED modules are mounted on bottom surfaces of the mounting plates of the mounting members of the heat sink, respectively. The extending plates have gradually decreased lengths from two central ones thereof toward lateral ones thereof. The mounting plates and the bottom surface of the base form acute angles which are gradually decreased from a center of the base to lateral sides of the base.
