Abstract
The utility model discloses a focusing light projector, which is characterized in that the utility model comprises two or more light sources combined together; a cylinder is arranged on each light source; the light source is arranged on one end of the cylinder; two convex lenses are arranged in the middle part of the cylinder and on the other end of the cylinder respectively; all of the cylinders are juxtaposed together. A parallel beam light is formed when the light given off by the light sources is refracted by a first convex lens. The parallel beam is focused in a spot after refracted by a second convex lens; thus a facula which has a uniform distribution and a strong light intensity is formed. A plurality of beams are combined together and focused after refracted by the two convex lenses and then projected to an area; thus the illumination of the light projector is strengthened.
Description
Technical field
The utility model relates to a kind of light projector device, particularly a kind of light projector that can project small size, not astigmatic, high brightness hot spot on remote.
Background technology
Present light projector can project a small size hot spot on remote, this hot spot is by the small size light source and the convex lens before being arranged on the small size light source form, when the distance of convex lens and small size light source just in time was the focal length of convex lens, the light planoconvex lens refraction back that the small size light source sends formed a parallel beam.Yet traditional light projector has defectives such as the light intensity of inhomogeneous, easy astigmatism of the distribution of light of formed hot spot and hot spot is difficult to be protected.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provide a kind of distribution of light evenly, the stronger light projector of light intensity not astigmatic, hot spot.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of focusing light projector, it is characterized in that it comprises the light source that two or more are combined, be provided with a cylindrical shell on each light source, light source is arranged on an end of cylindrical shell, middle part and the other end at cylindrical shell are respectively arranged with convex lens, and each cylindrical shell stacks together side by side.
Above-mentioned light source can adopt the LED lamp, also can adopt common emitting bulb.
Above-mentioned light source preferably is positioned on the focus of middle part convex lens.
The beneficial effects of the utility model are: light projector of the present utility model adopts two or more light sources of combining, be provided with a cylindrical shell on each light source, light source is arranged on an end of cylindrical shell, middle part and the other end at cylindrical shell are respectively arranged with convex lens, each cylindrical shell stacks together side by side, when light formation one parallel beam after first convex lens refraction that light source sends, this parallel beam is focused in a bit after second convex lens refraction, thereby it is even to form a distribution of light, the hot spot that light intensity is stronger, and a plurality of light are combined, all focus on by two convex lens refraction back, the light that sends from light source like this, will be through after twice convex lens focus, just throw away, and this light projector is by two or more combination of light sources together that the light that each light projector projects can be overlapping, project same zone, thereby strengthened the brightness of light projector.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a schematic perspective view of the present utility model;
Fig. 2 is the cut-open view of single refraction structure.
Embodiment
With reference to Fig. 1, Fig. 2, a kind of focusing light projector disclosed in the utility model, comprise two or more light sources of combining 1 (there is shown the light projector structure that constitutes by six light sources), a plurality of light sources can adopt the form of parallel connection or series connection to combine, light source 1 can adopt the LED lamp, also can adopt common emitting bulb, on each light source 1, be provided with a cylindrical shell 2, light source 1 is arranged on an end of cylindrical shell 2, middle part and the other end at cylindrical shell 2 are respectively arranged with convex lens 3, light source 1 preferably is positioned on the focus of middle part convex lens 3, each cylindrical shell 2 stacks together side by side, when light formation one parallel beam after first convex lens refraction that light source sends, this parallel beam is focused in a bit after second convex lens refraction, thereby it is even to form a distribution of light, the hot spot that light intensity is stronger, and a plurality of light are combined, all focus on, project same zone, thereby strengthened the brightness of light projector by two convex lens refraction back.This focuses on light projector, can be applied to different products according to actual needs, as can be used as projection lamp, also can be used as electric torch and uses or the like.
It is above-mentioned that just the utility model is preferred embodiment a kind of; it does not constitute restriction of the present utility model; the utility model can also have other structural change; quantity as light source can also be two; also can be two with first-class; so long as the equalization of doing according to protection domain of the present utility model changes and modify, all should still belong in the scope that the utility model contains.
Claims (3)
