Abstract
The utility model relates to a miniature uniform-light lighting device, which comprises a light source, an integral light bar, a single-sided convex lens and a convex lens, wherein the integral light bar and the single-sided convex lens are connected into a whole. An object point of the utility model is positioned on a virtual surface inside the light bar, so that the problems of non-uniform brightness of light spot and shadow caused by the surface precision error and uncleanness of the light bar are solved, and the structure is compact and the cost is low.
Description
Technical field
The utility model relates to a kind of miniature even illuminating apparatus.
Background technology
At present, in miniature spot shaping and even optical illumination field, the even employed optical wand of lighting system is based on mainly that glass material makes, be cuboid or prismatoid, with the hot spot that reaches a certain size uniform luminance after the biconvex lens combination in target face, as shown in Figure 1, though this mode can realize the function of even optical illumination, but the surface figure accuracy sum of errors clean level of the A face of optical wand can be amplified by two convex lens combinations in manufacture process, cause in the target area of illumination and form the hot spot brightness irregularities, even problem such as shadow is arranged, the amplification of two convex lens is big more, the problem that appears is obvious more, has influenced even optical illumination quality greatly.
The utility model content
The utility model aims to provide a kind of miniature even illuminating apparatus, can effectively avoid at problems such as target area generation hot spot brightness irregularities or shadow, compact conformation.
A kind of miniature even illuminating apparatus comprises light source, the integration optical wand, and the single face convex lens, convex lens, described integration optical wand and single face convex lens are one.
Further, described integration optical wand and single face convex lens are plastic cement material.
Further, described light source is a led light source.
Object point of the present utility model is on virtual of optical wand inside, avoided because the unholiness problems such as the even shadow of hot spot brightness disproportionation that cause of surface accuracy sum of errors of optical wand, and compact conformation, cost is low.
Description of drawings
Fig. 1 is existing miniature even illuminating apparatus schematic diagram.
Fig. 2 is the utility model structural representation.
Among the figure: 1-light source, 2-integration optical wand, 3-single face convex lens, 4-convex lens, 5-working face.
The specific embodiment
As shown in Figure 2, the utility model is spared illuminating apparatus, comprises light source 1, integration optical wand 2, and single face convex lens 3, convex lens 4, integration optical wand 2 and single face convex lens 3 are one, and preferred, light source 1 is a led light source, and integration optical wand 2 and single face convex lens 3 are plastic cement material.After light sends from light source, reach and optical wand all-in-one-piece single face convex lens 3 through integration optical wand 2, convex lens 4 impinge upon on the working face 5 equably.Existing relatively miniature even illuminating apparatus, the utility model has been cancelled the A face of integration optical wand 2, thereby has avoided owing to integration optical wand 2 surface accuracy differences and the unholiness problems such as the even shadow of hot spot brightness disproportionation that cause, and compact conformation, and cost is low.
Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
