Abstract
The utility model discloses a high-efficiency spot light which comprises a point light source, a concave mirror and a lens set. The inner surface of the concave mirror is a smooth spherical concave. A concave lens and a convex lens are sequentially arranged in the lens set in the direction of emitting light of the light source. The focus of the concave mirror coincides with the focus of the concave lens. The concave mirror and the concave lens are arranged on the two sides of the focus. The focus of the convex lens coincides with the virtual focus of the concave lens. The distance between the convex lens and the concave lens is smaller than the focal distance of the convex lens. The high-efficiency spot light is simple in structure and good in light ray converging effect, increases the light converging effect of the spot light, improves the remote searchlighting capability of the spot light, meanwhile, reduces dissipation of light rays in the conveying process, improves the energy utilization rate of the spot light and facilitates improvement of the power of the spot light.
Description
Technical field
The utility model relates to a kind of long-range searchlighting light source, particularly a kind of high-effective concentration lamp.
Background technology
Spotlight is that the light that utilizes optical device that lens or other are relevant that spot light or line source or area source are sent converges the angle of divergence with less in scope at one end and penetrates, and a kind of light source of assurance range of exposures internal radiation intensity stabilization equilibrium, modal is exactly various searchlights and signal lamp, and spotlight is widely used in fields such as making scape, detection, normal signal transmission, photography now.Present spotlight mainly contains following two speciogenesis patterns, and the first arranges convex lens before light source, light is forwards converged to ejaculation; It two is that a reflector is set after light source, and the light break-in that light source is penetrated is backward assembled to penetrate and realized spotlight effect.It is large that two kinds of spotlights so all exist source light to dissipate, and the irradiant angle of divergence is very large and homogeneity is not high, and energy dissipation is serious, and energy utilization rate is not high, and irradiation distance depends critically upon the luminous power of light source etc.
The utility model content
For addressing the above problem, the utility model discloses a kind of high-effective concentration lamp, simple in structure, good to the light convergence effect, increased the spotlight effect of spotlight, improved the long-range searchlighting ability of spotlight, improved the irradiation power of spotlight.
The disclosed high-effective concentration lamp of the utility model, comprise spot light, concave mirror and set of lenses, the inner surface of described concave mirror is the smooth, spherical concave surface, in described set of lenses, be disposed with concavees lens and each a slice of convex lens along light source emergent light direction, the focus of described concave mirror overlaps with the virtual focus of concavees lens and concave mirror and concavees lens are arranged on the focus both sides, and the focus of described convex lens overlaps with the virtual focus of concavees lens and the spacing of convex lens and concavees lens is less than the focal length of convex lens.The disclosed high-effective concentration modulated structure of the utility model is simple, volume is little, by the set of lenses arranged, adjust the propagation path of light source emergent light, strengthen the spotlight effect of spotlight, improved the long-range searchlighting ability of spotlight, also reduced simultaneously the dissipation of source light in the process of converging, improve the energy utilization rate of spotlight, be conducive to improve the power of spotlight.
A kind of improvement of the disclosed high-effective concentration lamp of the utility model, described concave mirror are concave lens, and the outer surface of described concave lens is provided with the reflective array by the adjacent setting of equilateral right-angle prismatic cone.This improvement is reflected break-in by the reflective array that arranges to the rearward refracted ray of spotlight light source, thereby has reduced the dissipation of spotlight energy of light source, has improved the utilization rate of spotlight energy of light source, is conducive to promote lighting effect.
Another of the disclosed high-effective concentration lamp of the utility model improved, and described spot light is arranged on the focus place of concave mirror inboard.This improvement is arranged on spot light at the focus place of concave mirror, makes concave mirror to focus on break-in to light, thereby has promoted the convergence effect of spotlight to source light, promotes light efficiency and the energy utilization efficiency of spotlight.
The disclosed high-effective concentration lamp of the utility model, simple in structure, easy to use, the light convergence effect that light source is sent is good, is conducive to promote the intensity of illumination of spotlight, has improved energy utilization efficiency.
The accompanying drawing explanation
The structural representation of Fig. 1, the disclosed high-effective concentration lamp of the utility model;
Reference numerals list:
1, spot light; 2, concave mirror; 3, convex lens;
4, reflective array; 5, concavees lens.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand the following specific embodiment and only be used to the utility model is described, be not used in restriction scope of the present utility model.
As shown in Figure 1, the disclosed high-effective concentration lamp of the utility model, comprise spot light 1, concave mirror 2 and set of lenses, the inner surface of described concave mirror 2 is the smooth, spherical concave surface, in described set of lenses, be disposed with concavees lens 5 and convex lens 3 each a slices along light source emergent light direction, the focus of described concave mirror 2 overlaps with the virtual focus of concavees lens 5 and concave mirror 2 and concavees lens 5 are arranged on the focus both sides, and the focus of described convex lens 3 overlaps with the virtual focus of concavees lens 5 and convex lens 3 and the spacing of concavees lens 5 are less than the focal length of convex lens 3.The disclosed high-effective concentration modulated structure of the utility model is simple, volume is little, by the set of lenses arranged, adjust the propagation path of light source emergent light, strengthen the spotlight effect of spotlight, improved the long-range searchlighting ability of spotlight, also reduced simultaneously the dissipation of source light in the process of converging, improve the energy utilization rate of spotlight, be conducive to improve the power of spotlight.
As a kind of preferred, described concave mirror 2 is concave lens, and the outer surface of described concave lens is provided with the reflective array 4 by the adjacent setting of equilateral right-angle prismatic cone.By the reflective array that arranges, the rearward refracted ray of spotlight light source is reflected to break-in, thereby reduced the dissipation of spotlight energy of light source, improved the utilization rate of spotlight energy of light source, be conducive to promote lighting effect.
As a kind of preferred, described spot light 1 is arranged on the focus place of concave mirror 2 inboards.By spot light being arranged on to the focus place of concave mirror, make concave mirror to focus on break-in to light, thereby promoted the convergence effect of spotlight to source light, promote light efficiency and the energy utilization efficiency of spotlight.
The set of lenses of the disclosed high-effective concentration lamp of the utility model also can select a plurality of convex lens and concavees lens to combine to reach better spotlight effect, and by control, control the focal length of each lens and can control the spot size of the emergent light of final output, thereby adjust as required the needs that spotlight effect meets applied environment.
The disclosed high-effective concentration lamp of the utility model, simple in structure, easy to use, the light convergence effect that light source is sent is good, is conducive to promote the intensity of illumination of spotlight, has improved energy utilization efficiency.
