Specific implementation mode

Your auditor there can be further understanding to the technological means and operation of the present invention for ease of and understand, it is existing Citing cooperation attached drawing, detailed description are as follows.

The present invention provides a kind of light shield optical module, refering to Figure 1, the light shield optical module of the present invention includes：One Optical module 10, wherein the optical module 10 be using transparent plastic material extrude or injection molding, and penetration power up to 60% with On, wherein transparent plastic material can be PS, PC, PP, acrylic etc..

Please refer to shown in Fig. 2, Fig. 3, the optical module 10 have a smooth incidence surface 100 and one with the incidence surface The smooth light-emitting surface 101 of 100 settings opposite each other, and the light-emitting surface 101 is equipped with multiple microns of cell structures 11, Mei Gewei Rice cell structure 11 forms a recessed portion 1001 on the incidence surface 100；Wherein, each micron of cell structure 11 is respectively provided with one First inclined-plane 111 and one second inclined-plane 112 have a plane 113 between first inclined-plane 111, the second inclined-plane 112, make this Inverted ladder type is presented in the section of rice cell structure 11 slightly；Also, the incidence surface 100 and light-emitting surface 101 are alternatively through AG (Anti Glare) the AG atomization faces of atomization process can so cover such as light bulb, fluorescent tube or LED light light at 10 rear of optical module Source.
