Abstract
The utility model discloses a light-condensed collimation optical structure which comprises a reflection cup substrate (1), wherein a reflection cup body (2) is arranged above the reflection cup substrate (1); and a lens (3) is arranged between the reflection cup substrate (1) and the reflection cup body (2). The light-condensed collimation optical structure has the respective advantages of a reflection cup and the lens in the aspect of collimation light condensation, can improve reflection efficiency, maintenance factors and irradiation efficiency, and solves the problem that spill lights occur at the periphery of light spots; and according to the light-condensed collimation optical structure, materials are saved and production cost is lowered.
Description
Technical field
The utility model relates to a kind of optical texture, particularly a kind of optical texture of energy optically focused collimation.
Background technology
At present, the LED illumination is used more and more widely because of advantages such as environmental protection and energy saving, so the market prospects of LED secondary lens also are expected thereupon.Because the luminous characteristics of LED is the nearly lambert's type of half-plane, so needing adapted LED secondary light-distribution device when collimating optically focused adjusts light, conventional LED secondary light-distribution device is single reflector, perhaps single lens, adopt the former optical module reflection efficiency and maintenance factor all very low, and all can occur the astigmatism of overflowing around the hot spot that produces, be unfavorable for the efficient collimation of light; It is low to adopt single lens to carry out the light extraction efficiency of LED optical module of luminous intensity distribution, particularly in the situation of carrying out low-angle optically focused collimation lens whole long-pending can be very large, be easy to cause a large amount of wastes of material and increasing considerably of production cost.
The utility model content
The purpose of this utility model is, a kind of optically focused collimating optics structure is provided.The utlity model has the advantage of each comfortable Quasi-straight light-focusing aspect of reflector and lens, both can improve reflection efficiency, maintenance factor and the efficient of setting out, also solved hot spot and the problem of astigmatism of overflowing can occur on every side, and saved material, reduced production cost.
The technical solution of the utility model: a kind of optically focused collimating optics structure, comprise the reflector pedestal, reflector pedestal top is provided with the reflector cup, and the centre of described reflector pedestal and reflector cup is provided with lens.
In the above-mentioned optically focused collimating optics structure, described lens are Fresnel Lenses.
In the aforesaid optically focused collimating optics structure, described lens side is fixed with a fixed mount, and the end of fixed mount is erected on the reflector pedestal; The reflector cup be located on the reflector pedestal, and fixed mount is fastened between reflector pedestal and the reflector cup.
In the aforesaid optically focused collimating optics structure, described fixed mount is the cross fixed mount.
Compared with prior art, the utility model unites two into one reflector and lens, make the advantage that the utlity model has reflector and each comfortable Quasi-straight light-focusing aspect of lens, reflection efficiency, maintenance factor and the efficient of setting out both can have been improved, the astigmatic problem of overflowing can appear around also having solved hot spot, and saved material, reduced production cost.In addition, the applicant also is optimized the concrete assembling of reflector and lens, and namely lens fix between reflector cup and reflector pedestal, and that the scheme after the optimization has is simple in structure, fixation, advantage convenient for installation and maintenance.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is schematic perspective view of the present utility model.
Being labeled as in the accompanying drawing: 1-reflector pedestal, 2-reflector cup, 3-lens, 4-fixed mount.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment, but not as to restriction of the present utility model.
Embodiment of the present utility model: a kind of optically focused collimating optics structure, as shown in Figures 1 and 2, comprise reflector pedestal 1, reflector pedestal 1 top is provided with reflector cup 2, and the centre of described reflector pedestal 1 and reflector cup 2 is provided with lens 3; Described lens 3 are Fresnel Lenses.The side of described lens 3 is fixed with a fixed mount 4, and fixed mount can be in-line, three fork-shapeds or cross, and the end of fixed mount 4 is erected on the reflector pedestal 1; Reflector cup 2 be located on the reflector pedestal 1, and fixed mount 4 is fastened between reflector pedestal 1 and the reflector cup 2; Preferably, described fixed mount 4 is the cross fixed mount, and four of the cross fixed mount symmetrical fixings on the reflector pedestal of frame end difference cover the reflector pedestal with the reflector cup again, thereby realize uniting two into one of reflector and lens during installation.
