Abstract: An LED lamp includes a heat sink including a base and a plurality of fins extending from the base, an LED module mounted on a bottom face of the base, an envelope covering the LED module, and a lamp housing defining a cavity. An annular receiving groove is recessed from the bottom face of the base. The LED module is attached on the bottom face of the base and surrounded by the receiving groove. The envelope includes a recessed body and an engaging flange around the recessed body. The heat sink, the LED module and the envelope are received in the cavity. The fins of the heat sink extend outwardly through the lamp housing and are exposed in an outer environment. A gasket is received in the receiving groove and tightly sandwiched between the base and the flange.

Abstract: An LED lamp includes a connecting member and an LED module. The connecting member is adapted for electrically connecting with a power source. The LED module is clasped by and electrically connects to the connecting member.

Abstract: An LED lamp includes an enclosure, a base connected to a bottom of the enclosure, a cover connected to a top of the enclosure, an LED module received in the enclosure, a cap connected to a base, and a bracket fixed on the enclosure and pressing the cover on the enclosure. A first gasket is sandwiched between the bottom of the enclosure and the base, and a second gasket is sandwiched between the top of the enclosure and the cover. A driving module is received in the enclosure and isolated from the LED module by an interlayer formed in the enclosure.

Abstract: An LED assembly can effectively prevent static electricity from accumulation, comprises an LED module, a grounded support and two fasteners extending through the LED module into the support. The LED module comprises a printed circuit board having a metal substrate and two insulating layers formed on the substrate, and a plurality of LEDs mounted on the printed circuit board. Each fastener has a plurality of teeth extending downwardly through the insulating layer to abut against a top face of the substrate, to thereby electrically connect a top face of the insulating layer and the substrate.

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 first heat sink, a lamp base, a plurality of LED modules, an envelope and a second heat sink. The first heat sink includes a cylinder at a centre thereof and a plurality of fins surrounding the cylinder. The lamp base is secured to a bottom portion of the first heat sink. The LED modules are mounted on the fins of the first heat sink. Each of the LED modules includes a printed circuit board and a plurality of LEDs mounted on the printed circuit board. The envelope is mounted between the lamp base and the second heat sink and encloses the first heat sink and the LED modules therein. The second heat sink has a disc-like configuration, with a bottom connecting portion extending through the envelope to connect with a top portion of the first heat sink.
