Liquid-cooled light distribution hollow type LED lamp

Abstract

The invention discloses a liquid-cooled light distribution hollow type LED lamp comprising an electric connector, an LED drive, a lamp holder, an LED light source, a lamp shade and a hollow radiator,wherein the lamp shade is made of basically transparent materials. The liquid-cooled light distribution hollow type LED lamp is characterized in that a cavity positioned between the outer surface of the hollow radiator and the lamp shade is internally partially or completely filled with heat-conducting light distribution liquid; the electric connector and the LED drive are arranged in a built-in hollow chamber of the hollow radiator; the LED light source is directly arranged on the hollow radiator or arranged on the hollow radiator through an LED basal plate; and a connecting wire of the LED light source is contacted with different radiating liquids. The invention has the advantages of good radiating effect, light weight, environmental protection, durability, easy manufacture and low cost.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an integrated LED lamp which uses liquid for heat dissipation and light distribution. Background technique [0002] With the development and maturity of high-power LED technology, the performance index of LED for lighting has been greatly improved day by day. At present, the luminous efficiency of industrialized white LEDs has reached (70-90) lm / W, far exceeding the luminous efficiency level of ordinary incandescent lamps. High-power LEDs will be more and more widely used in the field of lighting. It is the fourth-generation lighting source that replaces fluorescent lamps and incandescent lamps in the 21st century. [0003] However, since the LED must be below 80 degrees Celsius to obtain high light efficiency and long life, the thermal design requirements for LED lamps are very high. Poor heat dissipation will cause LED light decay, reducing luminous efficiency and service life. In order to obt...

Problems solved by technology

However, since the heat transfer liquid occupies more internal space, it also increases the weight of the product and the difficulty of installation, reducing the safety of the product, such as figure 2 shown

[0007] In addition, since the metal easily reacts electrochemically with the electrolyte in the cooling liquid at high temperature, it is difficult to choose the cooling liquid, and the sealing problem with the heat sink becomes very strict.
