HIGH POWER LED LAMP WITH HEAT DISSIPATION ENHANCEMENT

摘要

A high power LED lamp is provided to improve a heat radiation efficiency by using an axial heat conductor to deliver heat from an optical source module to a container through liquid. A high power LED(Light Emitting Device) lamp includes a container(202), a liquid(204), an optical source module, and an axial heat conductor(213). The container includes a cavity. The liquid is contained in the cavity. The optical source module provides a high power light emitting diode beam. The axial heat conductor includes first and second parts. The first part is close to the optical source module. The second part is elongated from the optical source module along an axial direction in the liquid. The axial heat conductor delivers heat from the optical source module to the container through the liquid.
