Abstract

The utility model relates to an integrated compound spectacle glass which comprises a first group of compound spectacle glasses and a second group of compound spectacle glasses, wherein the first group of compound spectacle glass and the second group of compound spectacle glass are connected into a whole. The utility model overcomes the error caused by non-concentric optical axis and inaccurate installation distance when a single-piece type compound spectacle glass is installed, a glass or optical plastic material with a low melting point is adopted, a mould can be used for processing, the production efficiency is high, and the cost is low. An optical material with the refractive index higher than the air refractive index is placed between the two groups of compound spectacle glasses, the distance between the two groups of compound spectacle glasses can be reduced, and the external volume is reduced.

Description

Integral type compound eye eyeglass

Technical field

The utility model relates to a kind of lighting device, particularly the compound eye eyeglass of homogenising illumination.

Background technology

At present; for the illuminating effect of obtaining; in the homogenising lamp optical system; regular meeting uses the combination based on two groups of compound eye eyeglasses of glass material to realize the shaping of hot spot and the homogenising of energy; as shown in Figure 1; it is the focus of two groups of compound eye eyeglasses that its operation principle requires the distance between the surface top of two set of contact lenses, therefore, and to the very high requirement that is equipped with of two set of contact lenses.Along with the miniaturization requirement of various use occasions of modern times to lamp optical system, have higher requirement in installation accuracy and interval to two groups of compound eye eyeglasses, because two groups of one chip compound eye mirrors are assemblings again after producing separately, the axiality of its optical axis is subject to the restriction of installation accuracy and the perfection that has a strong impact on its performance embodies, especially in little shape uniform illumination system, its installation difficulty is bigger, and the installation accuracy error is more obvious to Effect on Performance, therefore cause acceptance rate low, production efficiency is low.

The utility model content

The utility model aims to provide a kind of compound eye eyeglass of even illumination, and is easy for installation, the light shaft coaxle degree height of two eyeglasses, production efficiency height.

The technical solution of the utility model is: integral type compound eye eyeglass, comprise first group of compound eye eyeglass and second group of compound eye eyeglass, and first set of contact lenses and second set of contact lenses are linked as an integral body.

Preferably, integral type compound eye lens materials is a low-melting glass.

Preferably, integral type compound eye lens materials is the optics plastic cement.

The utility model has overcome one chip compound eye eyeglass when mounted because of optical axis decentraction and the inaccurate error that causes of mounting distance, adopts low-melting glass or optics plastic material, and available mould is processed, the production efficiency height, and cost is low.Between two groups of compound eye eyeglasses is the optical material higher than air refraction, can reduce distance between the two, reduces overall volume.

Description of drawings

Fig. 1 is the use schematic diagram of one chip compound eye eyeglass.

Fig. 2 is that the utility model integral type compound eye eyeglass uses schematic diagram.

Among the figure: the 1-light source, the 2-collimation lens, the group fly's-eye lens is organized fly's-eye lens behind the 4-before the 3-, the 5-lens that superpose, 6-surround, 7-integral type fly's-eye lens, first group of compound eye eyeglass of 71-, second group of compound eye eyeglass of 72-.

The specific embodiment

Be illustrated in figure 1 as existing homogenising lamp optical system, comprise light source 1, collimation lens 2, preceding group of fly's-eye lens 3, back group fly's-eye lens 4, stack lens 5 are surround 6 then, the installation accuracy of two groups of fly's-eye lenses requires high, and production efficiency is low, uses difficulty in little shape homogenising illuminator.

Figure 2 shows that the use schematic diagram of the utility model integral type compound eye eyeglass, be integral type fly's-eye lens 7 with the main distinction of existing homogenising lamp optical system, the integral type fly's-eye lens comprises first group of compound eye eyeglass 71 and second group of compound eye eyeglass 72, two groups of compound eye eyeglasses hold together, optical axis decentraction and the inaccurate illuminator quality that causes of mounting distance are not good when having overcome past two set of contact lenses owing to installation, and the miniaturization of homogenising illuminator and miniature can be realized preferably.By two arrangement of mirrors faces of precision die processing integral type compound eye eyeglass, axiality can obtain fine assurance, the production efficiency height.Simultaneously, integral type compound eye eyeglass adopts low-melting glass or optics plastic material to make, and is the material higher than air refraction between two set of contact lenses, makes it under the situation of identical performance requirement, and the distance between two set of contact lenses reduces, and has reduced volume.

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.
