Abstract: Provided is an omni-directional LED lamp including a lamp tube. The lamp tube includes an LED light source contained therein. In one embodiment, the LED light source includes at least one omni-directional LED lamp bar. Loose and light-permeable ceramic granule materials are filled into the lamp tube in a space between an inner wall of the tube and the LED light source. The loose light-permeable ceramic granule materials are coated on and contact to the irregular surface of the light source so as to reduce the thermal resistance and increase the heat conduction. Light diffuse reflection effects caused among the ceramic granules are positive that they can soften the light, reduce glaring and dazzling and prevent the blue light from leaking-out.

Abstract: An LED lamp including a glass lampshell and a stem assembly with one end inserted into the glass lampshell. The stem assembly comprises a glass trumpet tube with one end sealed within the glass lampshell to form a cavity within the glass lampshell and within the cavity a supporting component connected to the glass trumpet tube and supporting an LED emitter. The stem assembly further comprises a wire encompassed within the glass trumpet tube. The wire has one end extending outside of the cavity and the other end electrically connected to the LED emitter.

Abstract: An LED bulb uses an LED strip suspended between two lead frames of a stem as a light source to provide uniform illumination with wider angles. The lead frames of the stem provide an improved structural stability to the LED strip while maintaining a reliable electrical connection between the components of the stem and the LED strip. The utilization of both top-emitting and side-emitting LEDs on the LED strip further allows lights emitted in directions substantially parallel and perpendicular to the LED strip to cover a wide angle of illumination from the LED bulb.

Abstract: A high power LED lamp comprises a container having a cavity to fill with a liquid, a light source module for providing a high power LED source light to penetrate through the liquid, and an axial thermal conductor having a first portion nearby the light source module and a second portion extending in the liquid along an axial direction of the cavity to far away from the light source module to evenly transfer heat from the light source module through the liquid to the container.

Abstract: An LED lamp includes a container having a cavity containing a liquid, a light source module with a high power LED source to emit light through the liquid, and an thermal conductor having a first portion proximate the light source module and a second opposite portion extending in an axial direction of the cavity in front of the light source module.
