Problems solved by technology

[0002] Existing curved mirrors use reflective coatings on the surface or back to realize light reflection and light convergence. The disadvantages are that the coating is not firm enough, easy to be corroded and peeled off, easy to damage the coating during cleaning, short service life, and the coating cannot be achieved. Total reflection, low efficiency

Embodiment Construction

[0015] Referring to Fig. 1, the structure of this embodiment is that one layer of closely arranged porro prisms 1 are formed on one side of the optical glass, its right-angled prism 11 faces one example, and its slopes 12 are all on the same plane, and serve as the incident surface of light. In order to make the reflected light converge, it has a curved surface (paraboloid).

[0016] see figure 2 , the Porro prism 11 is composed of a high-refractive index reflective layer 2 and a low-refractive-index carrier layer 31, and closely arranged Porro prisms 21 are arranged on the high-refractive index reflective layer 2 , the carrier layer 3 with a low refractive index has the same prism 31 as the above-mentioned Porro prism 21, and the two are closely overlapped together to form a total Porro prism 1, and the refractive index n of the reflective layer 2 and the carrier layer 3 will satisfy i c <45°,

Abstract

A full-reflection curved mirror features that the porro prisms are closely arranged on the full-reflection curved surface in such manner that the inclined surfaces of all porro prisms are in a same plane. Its advantages are no need of reflecting film, high reflectivity and optical effect, and long service life.

Description

technical field [0001] The invention relates to a total reflection curved surface mirror, which is mainly used as a device for sunlight reflection and light convergence in solar energy utilization. Background technique [0002] Existing curved mirrors use reflective coatings on the surface or back to realize light reflection and light convergence. The disadvantages are that the coating is not firm enough, easy to be corroded and peeled off, easy to damage the coating during cleaning, short service life, and the coating cannot be achieved. Total reflection, low efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a total reflection curved mirror with high reflectivity and long service life, so as to overcome the deficiencies in the prior art. [0004] The technical scheme of the invention is: its total reflection curved surface is composed of closely arranged porro prisms, and the slopes of the porro prisms are all on the same p...
