Problems solved by technology

[0006] For the first heat dissipation method, since the single-lamp power LED is blocked by relatively static air, and the thermal conductivity of the air is only 1 / 26 of that of the optically coupled cooling liquid, although the heat energy transferred to the heat sink is absorbed by the aluminum heat sink Passed into the air, but the heat dissipation effect of the entire heat dissipation channel is not ideal
The second heat dissipation method, although a large amount of heat is taken away by the convective air, is much better than the first method, but a large amount of heat energy generated with the light emitting side must be transferred to the side opposite to the light emitting direction through the air before it can be transmitted. Can not meet the heat dissipation needs of the current LED power type LED integrated light source
The third structure is difficult to popularize because of its complex manufacturing technology, low defective rate and high production cost under the current process conditions.

Abstract

The invention provides an LED lamp radiating with optically coupled cooling liquid. An excellent heat-conducting optically coupled cooling liquid is filled between the luminous body of the outgoing end of the LED lamp and an enclosed shell so as to complete leakage-free encapsulation. Excellent heat-conducting properties and excellent optical characters of the optically coupled cooling liquid are used for realizing the improvement of the excellent heat conduction and optical characters between the luminous body of the LED lamp and the shell. When the radiating effect is needed to further improve, the optically coupled cooling liquid is forced to complete adequate heat exchange in a cold pool in the manner of pumping in the cold optically coupled cooling liquid and overflowing the hot optically coupled cooling liquid so that the junction temperature of the luminous body is maintained below 125 DEG C, so as to completely improve the radiating conditions of the luminous body in the LED lamp, prolong the service life of the LED lamp radiating with optically coupled cooling liquid with power LED integrated light source and the outgoing effect of the outgoing end.

Description

Technical field: [0001] The invention relates to an LED lighting fixture after high-density integration of a single lamp power type LED, especially a kind of light projection direction at the front end of the LED light source. Medium convective heat exchange, LED lamps filled with optically coupled coolant (commonly known as refrigerant) for heat dissipation, which have high transparency and high refractive index characteristics and can realize forced convective heat exchange under the action of external power. Background technique: [0002] Currently used LED lamps, as the brightness of high-density integrated power LED light sources continues to increase, the current density continues to increase (currently has reached 135Lm / w), so heat dissipation has become a very important issue in the integration and application of high-density integrated power LED light sources. The outstanding problem is that in order to keep the surface heat balance temperature of the single lamp po...
