Description of drawings
Fig. 1 is the structural representation of the led light source module of the utility model.
The Reference numeral implication is following:
The 1:LED light emitting diode; 2:LED beam angle lens; 3: circuit board; 4: cooling base; 5: circular radiator; 6: radiating fin; 7: heat pipe.
The specific embodiment
To combine Figure of description below, the utility model will be further described.
As shown in Figure 1, a kind of led light source module comprises a plurality of LED light emitting diode 1, circuit board 3, LED beam angle lens 2, cooling base 4 and radiator; A plurality of LED light emitting diodes 1 constitute the LED illumination module with LED beam angle lens 2, and the LED illumination module is installed on the circuit board 3, and circuit board 3 is installed on the cooling base 4; Radiator is positioned at the below of cooling base 4, and radiator comprises several layers circular radiator 5, and every layer of circular radiator 5 includes the radiating fin 6 and the heat pipe 7 that runs through some radiating fins of some vertical range upon range of settings; Many heat pipes 7 extend in the groove of cooling base 4 inside, and stretch out cooling base 4, and the height of the radiating fin 6 of each layer circular radiator 5 becomes stepped decline from the skin to the internal layer; And stretching out on the heat pipe 7 in each layer circular radiator 5 of cooling base 4 positions at many heat pipes 7 does not have radiating fin 6, through convection current highly different, that multilayer circular radiator 5 that be provided with breach causes air, Rapid Thermal exchange; Accelerate air and take away the speed of heat, can in the confined space, increase the area of heat radiation, heat is promptly distributed in outside air; Strengthen the effect of heat radiation; Prolong the service life and the intensity of illumination of cooling base 4, reduced the volume and the weight of led light source, when running into high wind and sleet; Led light source hangs on the lamp stand or is unable to hold out because of high wind, accumulated snow; And because of area Da Yi laying dust, thereby the effect of influence heat radiation and illumination, and the problem of inconvenient installation.
The number of plies of said circular radiator 5 is more than three layers or three layers, optimum selecting three-layer, and convenient design can also make led light source reach the purpose of high efficiency and heat radiation, and radiating fin 6 thickness of every layer of circular radiator 5 here are thin more, quantity is many more, and radiating effect is good more.
Said many heat pipes 7 adopt the multilayer capillary structure; Heat is refluxed at heat pipe 7; Heat pipe 7 is long more, and radiating effect is good more, contacts with air so the heat pipe of design stretches out cooling base 4; But because the restriction of led light source volume can only be decided the length that heat pipe stretches out fin slices radiator according to the design of shell situation of led light source.
The material that said cooling base 4, heat pipe 7 and radiating fin 6 adopt is copper or aluminium, good heat dissipation effect, and cost is lower.
In sum, the utility model utilizes the cooling base of copper or aluminum at first the heat that led light source produces once to be dispelled the heat, and the multilayer circular radiator of vertically being made up of some radiating fins then once dispels the heat once more; And different through the multilayer height, as to be provided with breach circular radiators causes the convection current of air, quickens airborne heat exchange, and radiator is the moulding of multilayer circular radiator; Can in the confined space, increase area of dissipation, heat is promptly distributed in outside air, heat pipe is provided with in the inner groove of cooling base; Increase the contact area of heat pipe and cooling base, be convenient to the heat conduction, strengthen the effect of heat radiation; Guarantee the service life and the intensity of illumination of led light source; And reduced the volume and the weight of led light source, and be convenient to install, have a good application prospect.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
