Find in the practicality that there is drawback in above-mentioned shadowless lamp lampshade structure: see Fig. 3; The inner surface of the over body case 1 that constitutes by the unit reflective mirror 101 of ladder plane shape; The light 7 of unit reflective mirror ring 2 reflections and 8 can be stopped by tube face and focusing system 10; Can not project the irradiated region on the plane 5, on irradiated region, cause the illumination of fixed position to lower, reduce the uniformity of shadowless lamp irradiation.
The utility model content
The applicant is to the above-mentioned shortcoming of existing reflection shield structure; The applicant studies and improves; Another kind of shadowless lamp reflection shield is provided, and the reflection ray of its inner ring reflective mirror ring can not receive stopping of tube face and focusing system, increases the illumination of shadowless lamp and the uniformity of irradiation.
The technical scheme that the utility model adopted is following:
A kind of shadowless lamp reflection shield comprises that the over body case of the shape of dehiscing, the top of said over body case have installing hole and be positioned at the peripheral installing ring of installing hole; The unit reflective mirror is in turn connected into unit reflective mirror ring along said over body case broadwise; Said each unit reflective mirror ring is dehisced to hold from said over body case and is connected successively to said installing ring direction; The unit reflective mirror that is on the same unit reflective mirror ring is of similar shape respectively and area; Dehisce end to said installing ring direction according to over body case, be in the area that the unit reflective mirror on the different units reflective mirror ring is of similar shape and progressively dwindles, so constitute the inner surface of said over body case; Be in the peripheral unit reflective mirror ring of installing ring on the said over body case inner surface and connected and composed by the unit reflective mirror of identical curve form, the unit reflective mirror of the said identical curve form warp-wise along said over body case respectively is crooked; Be in that remaining unit reflective mirror ring is connected and composed by the unit reflective mirror of same level shape respectively on the over body case inner surface, the unit reflective mirror of said same level shape is respectively the ladder plane shape.
The reflection ray of the peripheral unit reflective mirror ring of installing ring intersects respectively and drops on the irradiated region on the reflection shield lower, planar on the said over body case inner surface.
The beneficial effect of the utility model is:
Being in the peripheral unit reflective mirror ring of installing ring on the said over body case inner surface is connected and composed by the unit reflective mirror of identical curve form; The unit reflective mirror of the said identical curve form warp-wise along said over body case respectively is crooked; So change catoptrical light path; Make reflection ray intersect respectively and drop on the irradiated region on the reflection shield lower, planar, reflection ray can not receive stopping of tube face and focusing system, effectively increases the illumination of shadowless lamp and the uniformity of irradiation.
