Abstract
The invention discloses a hollow, liquid cooling and strip-shaped LED lamp, comprising an LED driver, an LED light source, and LED substrate, a light distributing lampshade, electrical connectors at two ends and a lamp socket. The invention is characterized in that a hollow inner container is set in the light distributing lampshade. The hollow chamber between the hollow inner container and the light distributing lampshade is filled with heat conducting liquid. The LED substrate is immersed in the heat conducting liquid. The invention conducts heat by conduction and convection of the heat conducting liquid, which can obtain good heat radiating effect. Meanwhile, the inner container and the light distributing lampshade form a hollow radiating shell filled with high performance heat conducting liquid, and the hollow radiating shell can be made of light weight materials. Therefore, the radiating shell is light in weight, environmental friendly, durable and low cost. Especially, since the heat conducting liquid fills in the hollow chamber of the hollow radiating shell directly in the invention, the heat radiating effect will be improved and at the same time the volume of the product wil…
