Abstract
The utility model provides a reflective Fresnel planar condenser, consisting of a lens and a reflecting film. The surface of the lens is provided with fine thread teeth, the surface of which is plated with a reflecting film which is covered by a lens back paint film. The surface of the lens back and the upper surface of the lens are covered with an enhanced film. A aluminum plate is arranged on the surface of the enhanced film and the back of the aluminum plate is provided with a fixed screw. Compared with the prior concave mirror, the utility model has the advantages of easy processing, low cost, small volume, convenient installation and use and wide range of usage. The utility model is mainly used in a reflective projector, a solar cooker, a solar collector and other reflective condensing systems and has great value for popularization and application.
Description
1, technical field
The utility model relates to a kind of optical mirror slip process technology, specifically a kind of reflective Fresnel planar concentrating mirror.
2, background technology
The condenser of prior art also is referred to as to call concave mirror, at present, condenser is mainly used in reflection type projection instrument, solar cooker, solar thermal collector and other reflecting condensation systems, mostly the condenser of prior art is the bonding one-tenth optically focused concave surface in pot shape concave surface with little glass mirror or corrosion resistant plate, the deficiency that this kind structure condenser exists in processing and use is, pot shape concave surface processing technology complexity, volume is big and processing cost is high, and is difficult for installing and using or the like.
3, summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of reflective Fresnel planar concentrating mirror is provided.
The technical solution of the utility model realizes in the following manner, this condenser is according to the Fresnel reflection principle, fine thread on the surface working of transparent organic glass eyeglass, the surface of thread is coated with reflective membrane, be coated with the mirror back lacquer film on the reflective membrane, the surface of mirror back lacquer and the upper surface of eyeglass are provided with reinforced film, and the reinforced film surface mutually bonding with the mirror back lacquer film is stained with aluminium sheet, and the back side of aluminium sheet is provided with set bolt.
The utility model has the advantages that: the structure of level crossing, the effect of concave mirror.Because this condenser is to be processed into by the tabular transparent organic glass, thereby, be easy to install and fix by double faced adhesive tape or other modes and other smooth surfaces, this concave mirror also have be easy to process, with low cost, volume is little and characteristics easy to install and that usable range is wide, be mainly used in reflection type projection instrument, solar cooker, solar thermal collector and other reflecting condensation systems, have good value for applications.
4, description of drawings
Accompanying drawing 1 is the structural representation of reflective Fresnel planar concentrating mirror.
Mark in the accompanying drawing is represented respectively; Reinforced film 1, eyeglass 2, thread 3, reflective membrane 4, mirror back lacquer film 5, aluminium sheet 6, set bolt 7.
5, embodiment
Below in conjunction with accompanying drawing reflective Fresnel planar concentrating mirror of the present utility model is done following detailed description the in detail.
As shown in drawings, reflective Fresnel planar concentrating mirror of the present utility model, its structure is made up of eyeglass 2, reflective membrane 4, mirror back lacquer film 5, reinforced film 1 and double sticky tape paper, surface working at transparent organic glass eyeglass 2 has fine thread 3, the surface of thread 3 is coated with reflective membrane 4, be coated with mirror back lacquer film 5 on the reflective membrane 4, the upper surface of the surface of mirror back lacquer film 5 and eyeglass 2 is provided with reinforced film 1, the surface that is positioned at the mutually bonding reinforced film 1 of mirror back lacquer film 5 is stained with aluminium sheet 6, and the back side of aluminium sheet 6 is provided with set bolt 7.
The tooth pitch of fine thread 3 is between 0.01-0.2 person of outstanding talent rice.
Mirror back lacquer film 5 is polyurethane resin paints.
Reinforced film 1 is a silicone resin.
Embodiment:
Thread is to form by fine thread mould compacting, and the machined parameters of fine thread mould tooth is calculated according to the Fresnel effect computing formula.
Installation and application:
Condenser of the present utility model can be installed and used on glass, plank, marble slab and particular stent, can also can pass through bolt by bonding, if adopt bonding use, elder generation is with its surperficial wiped clean during stickup, dry, take off being bonded at peeling paper on the double faced adhesive tape of condenser back then, the double faced adhesive tape at the condenser back side is attached to desires the card place; Firmly push the upper surface of condenser uniformly, condenser is promptly sticked on desire by double faced adhesive tape and pastes on the object surfaces, and is very efficient and convenient and save trouble.If by bolt, can use bolt and various sheet material or support to be connected and fixed, fixing purpose mainly is to prevent surface deformation, influences spotlight effect.
