Abstract
The invention discloses a radiating device of an LED (Light Emitting Diode) lamp. The radiating device comprises a substrate. At least one LED light emitting unit is arranged on the substrate. A passage for enabling heat exchange fluid to circulate is arranged in the substrate. One side of the substrate comprises an inlet and an outlet, wherein the inlet is used for enabling the heat exchange fluid to enter. A first circulation loop and a second circulation loop are serially connected between the inlet and the outlet. The heat exchange fluid is fluoride refrigerant or water. Since the radiating device of the LED lamp disclosed by the invention directly uses the passage which is arranged in the substrate and is used for enabling the heat exchange fluid to circulate and the fluoride refrigerant or water is used as carriers for heat exchange, a great amount of heat produced by the LED light emitting units can be rapidly taken away.
Description
Technical field
The present invention relates to a kind of lighting device, or rather, is a kind of heat abstractor of LED lamp.
Background technology
LED takes from the triliteral abbreviation of Light Emitting Diode, and Chinese is translated into " light emitting diode ", and as its name suggests, light emitting diode is that a kind of electronic device that electric energy can be converted into luminous energy has the characteristic of diode.The heat radiation approach of existing LED device mainly is heat conduction and thermal convection current, and the thermal conductivity that backing material is extremely low causes the device thermal resistance to increase, and produces serious self-heating effect, and the Performance And Reliability of device is produced destructive influence.In addition, heat concentrates in the small-sized chip, and chip temperature raises, and causes the sharp decrease in efficiency of penetrating of non-uniform Distribution, chip light emitting efficient and phosphor powder of thermal stress; When temperature surpassed certain value, the component failure rate is index law to be increased.Statistics shows, 2 ℃ of the every risings of component temperature, reliability decrease 10%.When a plurality of LED dense arrangement were formed white lumination system, the dissipation problem of heat was more serious.Solve thermal management issues and become the prerequisite that high-brightness LED is used.
Chinese invention patent ZL201110077388.1 discloses a kind of adopting surface mounted LED fin, and it comprises metal fin, and described metal fin is provided with the mounting groove of fitting with the electrode of peripheral hardware adopting surface mounted LED.A plurality of described metal fins connect in turn, have formed different adopting surface mounted LED heat-sink units again, behind adopting surface mounted LED heat-sink unit array, have formed different adopting surface mounted LED cooling systems.Adopting surface mounted LED fin among the present invention has better heat radiating effect, and the electrode paste that mounting groove is convenient to adopting surface mounted LED go into to be installed; The adopting surface mounted LED heat-sink unit is made up of the adopting surface mounted LED fin, has increased area of dissipation, has increased radiating efficiency; The adopting surface mounted LED cooling system is made up of the adopting surface mounted LED heat-sink unit, except further increase area of dissipation, can also adapt to various LED arrangement requirement.This fin need be in particular LED and arrange, and has occupied a lot of volumes, makes that the deadweight of LED lamp is excessive.
Summary of the invention
The present invention solves the existing in prior technology technical problem, thereby the heat abstractor of the led chip of the strong and compact conformation of a kind of heat-sinking capability is provided.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of heat abstractor of LED lamp comprises a substrate, and described substrate is provided with at least one LED luminescence unit, and the inside of described substrate is provided with the passage of heating load exchange liquid circulation.
As preferred embodiment of the present invention, a side of described substrate comprises an entrance and exit that supplies described exchange heat liquid to enter, and one first closed circuit and one second closed circuit are connected between the described entrance and exit.
As preferred embodiment of the present invention, the outside of described entrance and exit is provided with external connector.
As preferred embodiment of the present invention, described exchange heat liquid is the fluoride cold-producing medium.
As preferred embodiment of the present invention, described exchange heat liquid is water.
Because the heat abstractor utilization of LED lamp of the present invention is set directly at the passage that the inside of substrate is provided with the circulation of heating load exchange liquid, as the carrier of exchange heat, can take away a large amount of heats that the LED luminescence unit produces by fluoride cold-producing medium or water fast.
