The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 2,3, 4, it is the schematic diagram of the light source radiator group embodiment of the utility model LED projector equipment, the camera lens 41 that wherein ray machine 40 of above-mentioned LED projector equipment comprises LED light source module and is positioned at ray machine front, and LED light source module comprises two the first LED light source substrate 42(red, the green LED light source substrate for example that is positioned at ray machine 40 sides) and second LED light source substrate 43(who is positioned at ray machine 40 fronts blue led light source substrate for example); This radiator panel comprises the first radiator and the second radiator, wherein: the first radiator comprises positive the first radiating fin group 32 for attaching to the first copper base 31 of two the first LED light source substrates 42 and being positioned at first copper base 31 back sides; The second radiator comprises positive for fitting to the second copper base 21, heat-conducting copper pipe 22 and the second radiating fin group 23 of the second LED light source substrate 43; Heat-conducting copper pipe 22 one end is welded on the second copper base 21 back side, the other end is located in the second radiating fin group 23.
Particularly, heat-conducting copper pipe 22 can adopt hollow tube or solid post, and its axle is positioned at the plane that is parallel to the second copper base 21.
The LED light source that above-mentioned radiator panel is respectively different by the first radiator and the second radiator dispels the heat, the sidepiece that wherein the second copper base 21, heat-conducting copper pipe 22 and the second radiating fin group 23 are transmitted to ray machine by the heat of the LED light source in ray machine 40 fronts dispels the heat again, with respect to directly install the radiator of larger volume at the sidepiece of camera lens 41, can avoid radiator to protrude from camera lens 41, thereby guarantee that whole projector equipment has less volume.
In the light source radiator group of above-mentioned LED projector equipment, the second copper base 21 and the second LED light source substrate 43 are perpendicular to the projecting direction of the camera lens 41 of ray machine 40.Above-mentioned the second radiating fin group 23 comprises a plurality of fins perpendicular to the second copper base 21, and heat-conducting copper pipe 22 is welded and fixed perpendicular to the fin in the second radiating fin group 23 and with each fin.Like this, between fin, form gas channel, can directly heat be discharged to the front end of camera lens 41 by gas channel.
