Liquid cooling LED lamp

Abstract

The invention discloses a liquid cooling LED lamp which comprises a lamp seat, a heat abstractor arranged on the lamp seat and a heat conductive column fixed on the heat abstractor, wherein the heat conductive column is wound with a flexible circuit board along the side face and top face thereof, the flexible circuit board is provided with a plurality of LEDs, a transparent outer cover is sheathedat the periphery of the LEDs and fixed on the heat abstractor, and the transparent outer cover and the heat abstractor form a cavity filled with liquid. In the invention, as the cavity formed by thetransparent lamp cover and the heat abstractor is filled with heat conductive liquid, heat generated by the LEDs can be abundantly transmitted to the heat abstractor and the transparent outer cover bythe heat conductive liquid, thus improving the overall radiating effect of the lamp, reducing heat of the LEDs and improving the light emission efficiency. Simultaneously, the LEDs are wound on the side face and the top face of the heat conducting device by the flexible circuit board, thus improving the production efficiency of products and causing the light emission effect of the lamp to be moreeven.

Description

【Technical field】 [0001] The invention relates to a lighting fixture, in particular to a liquid-cooled LED lighting fixture. 【Background technique】 [0002] With the rapid development of LED technology, especially the advent of high-power LEDs, it has become possible for LEDs to be used in general lighting, and quickly set off a trend of green lighting in the world. However, since high-power LED itself generates a lot of heat, how to successfully help high-power LED dissipate heat has become a top priority in the design of LED lighting fixtures. At first, people designed various heat sinks on the LED lamps to help the LED lamps dissipate heat. This radiator includes a plurality of heat dissipation fins. These fins can increase the heat absorption and heat dissipation area, thereby improving the luminous efficiency of the LED. Later, due to the needs of commercial lighting, the power of LED lamps continued to increase, and the ensuing heat dissipation problem became more and...

Problems solved by technology

However, when the heat of the LED itself is transferred outward, in addition to accumulating a large amount of heat in the heat dissipation substrate, the lamp cap of the LED also accumulates a large amount of heat. Heat dissipation, the heat dissipation effect is not ideal, so that the temperature of the chip cannot be effectively controlled, and the efficiency of the lamp is still very low
