Include: image providing section 101 attaches to the first light distribution enlarging section 102 and attachment and the second of the first light distribution enlarging section 102
Light distribution enlarging section 103；Wherein:
Image providing section 101, for providing illumination image, internal illumination light source 1011 and image composer part, inside
The structure of structure and required light source 1011 and image composer part part is adapted, and protrusion, is attached with radiator on the right side of outer rim,
With the long rectangular space built-in light source 1011 of the radiator coupling part, the radiator is used to distribute the heat of light source, keeps away
Exempt from light source 1011 and cross heat-induced damage under closed environment, the light source 1011 provides illuminating ray to image composer part, can
Think LED or other available light sources；101 left end of image providing section is connected with the first light distribution enlarging section 102, and described be connected can be with
It is to be mechanically connected by the bolt of left lower or nut etc..Described image generating device is the light transmission with predetermined pattern
Exposure mask, the photo mask including multiple subgraphs can be selected LCoS escope, LCD type display or DLP escope or other
It is capable of providing the display of photo mask pattern.
First light distribution enlarging section 102 has columnar appearance, and built-in optical structure, the optical texture is by eyeglass
Composition realizes the expansion distribution of different demands, wherein the number of eyeglass for the optical path to illumination image by the refraction of eyeglass
Amount can be configured according to the effect of actually required optical path distribution to be achieved, in the present solution, including more than two balls
Face eyeglass and at least one aspherical lens and eyeglass is coaxial, realize the first time amplification of image, can be with comprising spherical surface in eyeglass
Realize better amplification effect.Eyeglass can be formed using optical glass material or optical resin material.One end is mentioned with image
It is connected for portion 101, the outer edge contour and image providing section 101 of coupling part are consistent；One end and the second light distribution enlarging section 103
