Mainly installed half-cover type above the illuminant (1〇2) Light-transmissive cover (101) 'The inner side surface (103) of the cover has a reflective effect. Such a luminaire prevents the illuminating body from causing glare and glare to the eyes. 'The atomization treatment is usually performed on the surface of the illuminant to reduce the aforementioned phenomenon. For outdoor lighting, due to environmental considerations, the full-cover lampshade (please refer to Figure B) is mainly used, and the light-transmitting lampshade (1〇4) below is also atomized to avoid direct eye-illuminating. Glare phenomenon. Both have common shortcomings, and the loss of multi-brightness due to the loss of the atomization process. SUMMARY OF THE INVENTION The present invention provides an anti-glare grating plate that utilizes optical reflection, refraction, and Ss boundaries in order to improve the brightness loss caused by atomizing treatment on the surface of the illuminator or the surface of the translucent lampshade to avoid eye glare. The angle-specific design can be applied to a variety of lighting fixtures to prevent the eyes from directly seeing the illuminance of the illuminator in the luminaire, and to soften the light with minimal loss of brightness. In this way, the lighting fixtures are softened and not glare when the brightness loss is minimized, and it is suitable for home lighting, such as office, factory and road, to avoid glare. An anti-glare grating plate provided by the present invention is a light-transmitting plate comprising at least a plurality of convex lens grating portions and a plurality of wedge-shaped grating portions on a bottom surface thereof.

Through the flat surface of the transparent plate and the convex lens to the illumination zone 200918824, the secondary refraction will be passed. This can minimize the brightness loss in the brightest area of the light directly below the illuminator and can be used to view the brilliance of the glare. Light and energy saving effects. Please refer to the sixth figure, the sixth Agj and the sixth BBj, which are the fifth embodiment of the anti-glare peach board of the present invention, which is a circular light-transmissive plate (10), and the bottom surface thereof is formed as the majority of the fourth figure. Annular wedge grating (10)) and multifilament convex lens grating (5Q4), the peripheral surface of the top surface is a flat surface (10)), and a plurality of strip-shaped convex lens gratings (10) are formed in the middle region, and the direction of the stripe convex lens and the other surface are recorded. The stripe convex lens grating (5〇4) direction is arranged at ninety degrees and arranged, which can minimize the brightness loss of the brightest area under the illuminating body and turn the glare glare into a lattice-like soft light to achieve anti-glare and energy saving effect. Please refer to the seventh, seventh and seventh (10), which are the sixth embodiment of the anti-glare peach plate of the present invention, which is a circular light-transmissive plate (deleted a), and the bottom surface is formed as the fifth A plurality of annular wedge gratings (503a) and a plurality of stripe convex lens gratings (5〇4a) are formed on the top surface, and a plurality of strip-shaped convex lens gratings (505a) are formed on the top surface, and the plurality of strip-shaped convex lens gratings in the direction of the strip-shaped convex lens grating and the other surface The grating (5〇4a) direction is arranged at ninety degrees and arranged, which can minimize the brightness loss of the lightest area under the illuminating body and can turn the glare glare into a lattice-like soft light to achieve anti-glare and energy saving effects. Moreover, the light that penetrates the strip-shaped wedge grating (5〇3a) of the transparent plate (501a) can be prevented from causing a particularly bright spot phenomenon of the block. Of course, the above figures are only preferred embodiments of the present invention, but simple or equivalent changes made according to the technical idea of the present invention, for example, most of the wedge-shaped gratings are arranged in an elliptical ring shape around the convex portion of the convex lens. To form an elliptical anti-glare grating plate, it is still within the scope of patent protection of the present invention. 11 200918824 [Simple description of the drawings] The first A is a schematic diagram of a conventional half-hood lighting fixture, the first B is a schematic diagram of a conventional full-cover lighting fixture, and the second diagram is the bottom surface of the first embodiment of the present invention.
