Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Specific embodiment 1:
See Fig. 1 to Fig. 3, the present embodiment relates to the camera lens of light fixture, and described light fixture comprises protecgulum 1 and bonnet 2, and protecgulum 1 covers on bonnet 2, the accommodating cavity 3 of inner formation, and described camera lens is located in accommodating cavity 3; It is characterized in that: also comprise lamp pearl plate 4, first lens 5, focusing lens plate 6 and the telescope motor 7 be located on bonnet that set gradually, described lamp pearl plate 4 is provided with some LED lamp bead 41, described first lens 5 cover is combined in described LED lamp bead 41, described focusing lens plate 6 is provided with second lens 61 corresponding with described first lens 5, and the light that LED lamp bead 41 sends is refracted to the second corresponding lens 61 through the first lens 5; The power output shaft of described telescope motor 7 is fixedly connected with focusing lens plate 6, drives focusing lens plate 6 slide thus regulate the distance between focusing lens plate 6 and the first lens 5 to focus by the stretching motion of power output shaft.Bonnet 2 fixedly mounts several telescope motor 7, the output shaft of telescope motor 7 can slide axially, work simultaneously pull focusing lens plate 6 back and forth movement by controlling multiple telescope motor 7, to regulate distance between focusing lens plate 6 and the first lens 5 and image distance, thus control the aperture size of the light beam through adjusting the second lens 61 to penetrate.Further, in accommodating cavity 3, control circuit is set, and the output of control circuit is connected with the control input end of telescope motor 7, described control circuit adopts single-chip microcomputer or PLC control circuit, the displacement of the output shaft of telescope motor 7 is accurately controlled, there is light beam regulation feature accurately, fast and easily.
Light barrier 8 is provided with between described first lens 5 and focusing lens plate 6, the surface of described light barrier 8 is provided with the boss 81 corresponding with described first lens 5, and having through hole 82 through described boss 81, described through hole 82 is set on the first lens 5 first lens 5 enclosing is inner at boss 81.The inside, upper surface of described boss 81 offers the chamfering 83 of the angular range for limiting the light launched from the first lens 5, and the size of described chamfering 83 is 45 ~ 90 degree.The center line of described boss 81 and the center line of the first lens 5, second lens 61 coincide.As shown in Figure 3, this light barrier 8 is by being designed to different angles by the angular dimension of chamfering a, the light that can control to reflect from the first lens 5 can penetrate the scope of through hole, thus make the light penetrated all to be positioned on second lens corresponding with the first lens 5 on focusing lens plate by directive, namely the second lens 61 that each the first lens 5 is corresponding single, make light the second lens 61 that directive is corresponding separately reflected from each the first lens 5, assembled by the second single lens 61, congregational rate is good, light penetrates the high and distance of brightness.The light-emitting line solving the LED lamp bead 41 of diverse location can be gone here and there and is mapped on other second lens 61, causes light-ray condensing effect undesirable and then produce light and penetrate apart from not far problem.
The backplate 9 for strengthening focusing lens plate 6 structural strength is also provided with between described light barrier 8 and focusing lens plate 6, described backplate 9 offers the via hole 91 corresponding with described second lens 61, is installed on focusing lens plate 6 by backplate 9 in alignment with corresponding second lens 61 by via hole 91.
Because telescope motor 7 is installed on bonnet 2, its output shaft need pass lamp pearl plate 4, light barrier 8, backplate 9 successively and is fixedly connected with focusing lens plate 6 and drives focusing lens plate 6 to slide, described lamp pearl plate 4 offers the first through hole 42, corresponding with it, described light barrier 8, backplate 9 and focusing lens plate 6 offer the second through hole 84, third through-hole 92 and fourth hole 62, the output of described telescope motor 7 passes the first through hole 42 to fourth hole 62 successively and is fixedly connected with focusing lens plate 6.
As shown in Figure 3, the lamp pearl plate 4 being positioned at described LED lamp bead 41 surrounding has installing hole 43, and accordingly, described first lens 5 are in " n " type structure, its two ends plug-in mounting to enter in installing hole 43 thus is combined in the first lens 5 by LED lamp bead 41 cover, forms the first lens installation structure of plug-in.When installation the first lens 5, can only manually two of the first lens 5 end pin be inserted installing hole 43 or extract, can realize the installation of the first lens 5, installation be quick and convenient.
In order to locate the first lens 5 in the position of longitudinal direction, make the first lens 5 can be fixedly mounted on lamp pearl plate 4, through hole 82 bottom of described light barrier 8 is processed with inner face, to be pressed on described first lens 5 by described inner face and to be fixedly attached on bonnet 2, limiting the lengthwise movement of the first lens 5.
In order to make the shape and structure of each second lens 61 and between position relationship accurate, to improve the congregational rate of focusing lens plate 6 pairs of light, described second lens 61 are located on focusing lens plate 6 by integrated syndeton, and evenly lay the upper surface of full focusing lens plate 6.Processed focusing lens plate 6 by the structure of integration, the relevant position relation of the second lens 61 processed and contour structures and size can reach the requirement that the light simultaneously luminous to multiple LED lamp bead 41 focuses on better.
Above disclosedly be only a kind of preferred embodiment of the present invention, certainly can not limit the interest field of the present invention with this, therefore according to the equivalent variations that the claims in the present invention are done, still belong to the scope that the present invention is contained.
