Abstract

The utility model relates to a large-power LED project lamp. The place where the center of a radiator corresponds to one side of an LED chip is provided with a through hole; a radiating mechanism comprises a heat conducting pillar; the structure of the heat conducting pillar is a sealed hollow pillar body; the heat conducting pillar is internally formed into a circulatory cavity; the circulatory cavity is internally filled with cooling liquid; the heat conducting pillar is arranged in the through hole of the radiator in a matching way; and one end of the heat conducting pillar is tightly glued with the LED chip. The large-power LED project lamp accelerates the cooling speed with the heat pipe principle, the heat energy which is originally concentrated at one end of the radiator and is slowly conducted is conducted to the cooling liquid in the heat conducting pillar, the cooling liquid absorbs a larger number of heat energy to be evaporated and gasified, the steam flows into the other end to discharge heat energy under minute pressure difference to be condensed into liquid, and the liquid reflows to an evaporation section along porous material under the function of capillary force. With the continuous circulation, the heat energy is conducted from one end of the heat pipe to the other end thereof, and the heat energy is fast conducted to the part of the radiator with relative lower temperature to dissipate the heat. Therefore, the large-power LED project lamp gives full play to the function of the radiator and guarantees that the LED can work under proper temperature, thereby improving the stability and the reliability thereof, and prolonging the service life thereof.

Description

High power LED projector

Technical field

The utility model relates to a kind of LED light fixture, especially a kind of high power LED projector.

Background technology

Existing high power LED projector, what generally use is with there being the radiator of many bulge-structures to dispel the heat, radiator is installed in the led chip back, but the heat that dispels the heat in this way can not be transmitted to the radiator part far away apart from light fixture fast and effectively, this part radiator can not effectively be played a role, radiating effect is not ideal enough, cause high-power LED chip because working junction temperature is too high, thereby cause light decay excessive, directly influence the service life of Projecting Lamp, and cause the quick aging and the damage of peripheral correlated parts easily.

Summary of the invention

The purpose of this utility model is to overcome the defective of prior art, and a kind of high power LED projector that can dispel the heat rapidly is provided.

For achieving the above object, the utility model adopts a kind of high power LED projector, comprise installing handle, power pack, led chip and cooling mechanism, cooling mechanism comprises radiator, led chip is arranged on radiator one side, power pack is arranged on the opposite side of relative led chip on the radiator, there is through hole at corresponding led chip side center on the radiator, the structure of heating column is the hollow cylinder of sealing, and the inner torus that forms of heating column has the imbibition core on the torus wall, it is made of the capillary porous material, cooling fluid is housed in the torus, and heating column is arranged in the radiator through hole and with through-hole wall and fits tightly, and heating column one end and led chip fit tightly.

The utility model quickens cooling with heat pipe principle, the heat that led chip produces is transmitted to and connects the led chip end on the heating column, make the cooling fluid that connects the led chip end on the heating column be subjected to thermal evaporation to form steam earlier, steam flows to the low-temperature end away from led chip, can fast heat be conducted to the radiator around the low-temperature end by the imbibition heart, scatter and disappear away by distance L ED chip radiator far away, the cooling fluid that simultaneous temperature reduces flows back to by the effect of capillary force along porous material and connects the led chip end.So circulation endlessly, heat reaches the other end by an end of heat pipe, conducting heat to the relative low temperature of radiator fast partly dispels the heat, give full play to the effect of radiator, guaranteeing that LED is operated under the suitable temperature works, thus stability, reliability and the service life of having improved high power LED projector.

The utility model further is set to described radiator through hole cross section for circular; Described heating column is that cross section is circular hollow circular cylinder.

The utility model further is set to described heating column and is shaped as T-shape, and T-shape upper surface and led chip are close to, and the T-shape upper surface contact-making surface on the heating column is big, can hold bigger led chip.

The utility model is set to further that corresponding heating column T-shape upper surface offers suitable groove on the described radiator again, and the upper surface of heating column constitutes with groove that step is spacing to be cooperated, and it is tightr that heating column is connected with radiator.
