The specific embodiment
In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment the technical solution of the utility model is further introduced and explanation, but be not limited to this.
As depicted in figs. 1 and 2, a kind of led light source structure that is used for projector equipment of the utility model, comprise radiator 1 and be located at substrate 2 on the radiator 1, substrate 2 is fixedly connected by screw 21 and radiator 1, substrate 2 is provided with LED lamp group body 3, and LED lamp group body 3 comprises matrix 30 and is located at the adopting surface mounted LED illuminator 31 of several matrix distribution on the matrix 30.Several LED illuminators 31 be cascaded successively and connect with positive pole 32 and negative pole 33 that matrix 30 is provided with (anodal 31 and negative pole 32 connect with electric pin 20 electric conductivity on the substrate 2 by lead, electric pin 20 is used to weld the power line of external circuit); Matrix 30 and substrate 2 connect (binding face between the two is coated with Heat Conduction Materials such as silica gel) for fitting tightly.The extexine of LED lamp group body 3 is provided with the heat-resistant insulating layer 4 of printing opacity.LED illuminator 31 power are at 1.5W or more than the 1.5W; The quantity of LED illuminator 31 is more than 5 * 6 or 5 * 6.The rear end of radiator 1 is installed with radiator fan 5 (utilizing quick flow air to quicken heat radiation).The front end of LED lamp group body 31 is provided with even optical lens, and the purpose of even optical lens is light-ray condensing is penetrated equably, and this even optical lens can be combined by a plurality of lens.Even optical lens shown in Figure 3 is the light guiding lens group 6 that comprises first light guiding lens 61, second light guiding lens 62 and the 3rd light guiding lens 63 of three identical sizes.Even optical lens shown in Figure 4 is to comprise the first light guiding lens 61A, the second light guiding lens 62A that three sectional areas successively decrease successively and the light guiding lens group 6A of the 3rd light guiding lens 63A.By the structure of Fig. 4 as can be seen, adopt the light guiding lens of successively decreasing successively, can use more large-area LED lamp group, thereby further improve the brightness of led light source, because as projector equipment is many is flat contour structures, so need flat rectangle is made in the cross section of light guiding lens, LED illuminator in the LED lamp group also is flat distribution, as the quantity of LED illuminator is 5 * 10,7 * 15 or the like, when making LED lamp group that enough brightness can be provided, can also guarantee that the appearance and size of projector equipment does not increase.The light guiding lens group is fixed with the imaging housing as radiator is also many by the imaging housings support of projector equipment and fixing.
In sum, the utility model can concentrate in the very little zone led light source because of adopting powerful SMT adopting surface mounted LED illuminator, and then by even optical lens, the light of high brightness is penetrated to transparent liquid crystal display, constitute the projected image of high brightness; The utility model uses 1.5W or the above LED lamp source of 1.5W more than 30 or 30 in addition, projector equipment led light source of the prior art relatively, brightness provides more than 30%, can replace thermal light sources such as high-pressure metal lamp of the prior art, reduce the production cost and the use cost of projector equipment; And have energy-conservation effect, have good popularizing application prospect.
The above only further specifies technology contents of the present utility model with embodiment; so that the reader is more readily understood; but do not represent embodiment of the present utility model to only limit to this, any technology of doing according to the utility model is extended or recreation, all is subjected to protection of the present utility model.Protection domain of the present utility model is as the criterion with claims.
