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.
Claims19
An LED lamp, comprising:
- a container having a cavity;
- a liquid in the cavity;
- a thermal conductive carrier immersed in the liquid;
- a thermal conductive rod connected to a central portion of a front surface of the thermal conductive carrier, a long axis of the thermal conductive rod being substantially perpendicular to the front surface;
- and
- an LED light source module disposed on the front surface.

An LED lamp, comprising:
- a container having a cavity;
- a liquid in the cavity;
- a light source module disposed in the cavity and having a front surface surrounded by the liquid;
- an LED light source enclosed within the light source module and configured to provide light to the liquid through the front surface of the light source module, the front surface being interposed between the liquid and the LED light source;
- and
- a thermal conductor substantially enclosed in the cavity and having a first portion disposed adjacent the light source module and a second portion extending from the first portion in front of the light source module in a direction substantially parallel to a normal direction of a central portion of the front surface, at least a portion of the thermal conductor being immersed in the liquid.
