Abstract

The utility model belongs to solar energy condensing lens field discloses an all -round refraction formula condensing lens. All -round refraction formula condensing lens be the rotational symmetry structure, adopt the hemisphere face design, do not need any tracking means, both reduction in production cost by a wide margin can avoid the sum of errors instability that tracking means brought again. The all -round refraction formula condensing lens project organization is miniaturized, material selection polymethyl methacrylate plastics (PMMA) low price, and accessible injection -moulded integrated into one piece, and further reduce cost can realize the industrial production, application prospect is wide.

Description

Comprehensive refraction type light gathering mirror
Technical field
This utility model belongs to solar energy condenser lens field and in particular to a kind of comprehensive refraction type light gathering mirror.
Background technology
In today that energy problem becomes increasingly conspicuous, environmental pollution is increasingly serious, solar energy as one kind inexhaustible, use it Inexhaustible, cleanliness without any pollution green energy resource gets most of the attention.In the effectively utilizes of solar energy, adopted based on the solar energy of fiber optic conduction Optical illumination, solar concentrating photovoltaic power generation are to develop research field faster in recent years.Solar energy light collecting illumination is to combine the sun A series of technology such as tracking, lens focuss, lifts sun brightness in focal point, guides to needs by the optical fiber of high thang-kng rate and adopt The place of light.Concentration photovoltaic system is equally by the high-performance photovoltaic battery of sunlight to area very little using condenser system On, thus reducing the cost of system.Condenser system can effectively overcome the relatively low defect of solar energy irradiation surface density, but traditional The angular range that solar lighting system and concentration photovoltaic system receive light is less, in order to more fully utilize the sun Light is it is necessary to be aided with to twin shaft or single shaft sun tracking device.But the reliability of tracking system still needs to further improve at present, And be unfavorable for reducing system cost.
Content of the invention
This utility model for existing condenser can collect sun angular little, need to day follow the tracks of deficiency it is proposed that A kind of miniaturized structure, big receiving angle, do not need the comprehensive refraction type light gathering mirror of tracks of device.
Comprehensive refraction type light gathering mirror of the present utility model is it is characterised in that this condenser lens is rotational symmetric hemisphere face knot Structure, sphere inner surface top setting curl face type sawtooth, sphere inner surface some groups of arranged in co-axial alignment Saw blades of other local setting.
Described planarea type sawtooth stripe pitch is 0 ~ 0.5mm, and sawtooth between cog spacing is 0 ~ 0.5mm.
Described comprehensive refraction type light gathering mirror does not need any tracks of device for rotational symmetric hemisphere face structure, both may be used So that production cost is greatly lowered, error and unstability that tracks of device brings can be avoided again.Comprehensive refraction type light gathering Mirror design structure miniaturization, material selects polymethyl methacrylate (PMMA), and it is cheap, and can pass through injection molding one Body formed, further reduces cost, achievable industrialized production, application prospect is wide.
Brief description
Fig. 1 is the appearance profile schematic diagram of comprehensive refraction type light gathering mirror.
Fig. 2 is the schematic cross-section of plate condenser lenss.
Fig. 3 is the schematic cross-section of comprehensive refraction type light gathering mirror.
Specific embodiment
The utility model discloses a kind of comprehensive refraction type light gathering mirror, with reference to the accompanying drawings and detailed description to this Invention is described further.
Embodiment 1:Comprehensive refraction type light gathering mirror adopts rotational symmetric hemisphere face structure, and spherical radius is 50mm, burnt Away from for 80mm.
Set according to above-mentioned radius and focal length, calculate the arrange parameter of setting Saw blade inside sphere, and accordingly half Ball inner surface setting has a series of Saw blade of arranged in co-axial alignment, middle sawtooth individually designed for curl face type, other sawtooth adopt Planarea type.Sawtooth stripe pitch, and sawtooth between cog spacing be 0.3mm.
Direct light can only be assembled different from traditional plate condenser lenss, comprehensive refraction type light gathering of the present utility model Mirror, with the change of solar azimuth, the directional light of different azimuth all can pass through the sawtooth sequence of relevant position, through reflecting twice Converge to focal point, as shown in Figure 3.The sunlight assembled by solar cell using or fiber-optic transfer it is not necessary to any tracking Device, both can be greatly lowered production cost, can avoid error and unstability that tracks of device brings again.Comprehensive folding Penetrate formula condenser lenss design structure miniaturization, material selects polymethyl methacrylate (PMMA) cheap, and can be by injection Processing is integrally formed, achievable industrialized production.
