Abstract

The utility model discloses an LED searchlight which comprises a radiating cavity, a thermal module, a front end cover, an LED light source and a fan, wherein the fan is inlaid in the thermal module; an air inlet and an air outlet are formed in the radiating cavity; the thermal module comprises at least one heat pipe, a cooling fin array, a first radiating substrate and a second radiating substrate; the LED light source is arranged on one side of the first radiating substrate; the second radiating substrate is arranged on the other side of the first radiating substrate; and the heat pipe penetrates through the second radiating substrate and sleeved with the cooling fin array. During operation, heat generated by the LED searchlight can be quickly guided onto the cooling fin array through the heat pipe, and the heat is radiated to the outside of the radiating cavity from a heat flux channel formed among the air inlet, the air outlet and the thermal module through blowing by the fan.

Description

A kind of LED searchlight

Technical field

The utility model relates to searchlight field, relates in particular to a kind of LED searchlight.

Background technology

The conventional light source in searchlight field be take Xe lamp bulb as main at present, not only power is very large, and energy saving is bad, light efficiency is low, along with the maturation of LED technology, the technical scheme that LED light source is applied to searchlight also reaches its maturity, but one of feature of LED light source is the rising along with temperature, its light efficiency and life-span are how much demultiplications, cause the thermal component of LED searchlight all to need very large volume, increased weight and the cost of LED searchlight, and carried inconvenience; And if the volume and weight of the thermal component of LED searchlight is done little, can cause the illumination of LED searchlight and brightness limited by the Power Limitation of LED searchlight in less scope, can not play the object of real searchlighting, the scope of application has limitation.

Summary of the invention

It is high that the utility model is done when large weight and cost for the thermal component existing in prior art, and it is lower that thermal component is done one-hour rating, causes the defects such as illumination and brightness is limited, and a kind of new LED searchlight is provided.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

A kind of LED searchlight, comprise heat radiation chamber, heat radiation module, drive end bearing bracket, LED light source, described heat radiation chamber, heat radiation module are connected with drive end bearing bracket respectively, described LED light source is arranged on heat radiation module, also comprise fan, described fan is embedded in described heat radiation module, on described heat radiation chamber, is also provided with air inlet and air outlet.

When LED searchlight is worked, the heat that LED light source produces can be derived by heat radiation module rapidly, blowing through passing through fan again, by forming heat passage between the air inlet on heat radiation chamber, air outlet and heat radiation module, shed fast outside heat radiation chamber, the heat of generation in chamber dispels the heat while reduce using, make LED searchlight integral body when not increasing heat radiation modular volume, can increasing power, guarantee illumination and the brightness of LED searchlight.

As preferably, a kind of LED searchlight described above, described heat radiation module comprises at least one heat pipe, radiated rib array, the first heat-radiating substrate, the second heat-radiating substrate, described LED light source is arranged at the one side of the first described heat-radiating substrate, the second described heat-radiating substrate is arranged at the another side of the first heat-radiating substrate, described heat pipe runs through the second heat-radiating substrate, and described radiated rib array is socketed on described heat pipe.

The heat part that the first heat-radiating substrate can produce LED light source diffuses in air equably, another part is transmitted on the second heat-radiating substrate equably, by the second heat-radiating substrate, a heat part is dispersed in air equably again, another part also finally diffuses in air by hot pipe conducting in radiated rib array, under the blowing of fan, the heat in the chamber of dispelling the heat can be rapidly from air outlet diffuses to heat radiation chamber.

As preferably, a kind of LED searchlight described above, described heat pipe is U-shaped.Can conduct heat to better in radiated rib array, improve radiating efficiency.

As preferably, a kind of LED searchlight described above, described heat pipe quantity is four.Can guarantee radiating efficiency, the volume of the module of can avoiding again dispelling the heat is excessive and impact is used.

As preferably, a kind of LED searchlight described above, air inlet is conduit type air inlet, described air outlet is conduit type air outlet.Good heat dissipation effect and comparatively attractive in appearance.
