Abstract
The utility model discloses a linear fresnel lens, the liquor RFID electronic label comprises a substrate layer, the substrate layer upper surface has line array's the long inclined plane of sawtooth, and its characterized in that still has a plurality of perpendicular tos the miniature slot of the long inclined plane of sawtooth direction, the utility model discloses assembling into a straight line after making the sunlight incide linear fresnel lens, absorbing solar energy effectively, can be applied to solar thermal energy can absorption system and solar electric system.
Description
Technical field
This utility model relates to optical instrument field, particularly relates to a kind of linear Fresnel lens.
Background technology
Existing solar water heater directly accepts solar heat mainly by thermal-collecting tube, effect
Rate is low.And linear Fresnel lens can by solar energy in large area light source converge into a line and
Focal heat heater, gathering area big focal heat efficiency height is maximum bright spot.
Utility model content
The purpose of this utility model is to solve shortcoming present in prior art, and proposes
A kind of linear Fresnel lens, makes sunlight pool one after inciding linear Fresnel lens
Straight line, gets up solar absorption effectively.It is applied to solar energy absorption system and too
Sun can electricity generation system.
To achieve these goals, this utility model adopts the technical scheme that
A kind of linear Fresnel lens, including substrate layer, described substrate layer upper surface has linearly
The long inclined-plane of sawtooth of arrangement, it is characterised in that also have and some be perpendicular to the long inclined-plane of described sawtooth
The microchannels in direction.
Further, the facewidth on the long inclined-plane of described sawtooth is 1.2mm, and tooth depth is 0.87mm.
Further, described substrate layer is transparent PMMA substrate layer, PC substrate layer, PS base
One in sheet material layers or PP substrate layer.
Further, described microchannels is equidistantly uniformly arranged.
In this utility model, draw Fresnel optical principle, concentric circular sawtooth is launched and linear
It is arranged in substrate layer (PMMA, PS, PC an etc.) side surface, and on the long inclined-plane of sawtooth
The microchannels being evenly distributed so that light, through sawtooth refractive, changes the refraction of serrated face oblique angle
After bright finish angle change the most therewith, effectively directional light can be pooled straight line and rise
To focussing force.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation front view；
Fig. 2 is this utility model structural representation top view；
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, in this utility model embodiment
Technical scheme be clearly and completely described, it is clear that described embodiment be only this
The a part of embodiment of utility model rather than whole embodiments.
Seeing figures.1.and.2, a kind of linear Fresnel lens, including substrate layer 1, substrate layer
1 upper surface has linearly aligned sawtooth long inclined-plane 1-1, also have some spaced sets and
It is perpendicular to microchannels 1-2 in 1-1 direction, described sawtooth long inclined-plane.Wherein, the long inclined-plane of sawtooth
The facewidth of 1-1 is 1.2mm, and tooth depth is 0.87mm.Substrate layer 1 can be transparent PMMA
One in substrate layer, PC substrate layer, PS substrate layer or PP substrate layer.
The sawtooth long inclined-plane 1-1 of this utility model linear Fresnel lens and microchannels 1-2 warp
Cross roll-in method one-shot forming.
Directional light is pooled straight line by this linear Fresnel lens, oblique by changing sawtooth length
The angle of face 1-1 and different arrangement, can adjust convergence angle and obtain Energy distribution, it is achieved be right
Effective conversion of solar energy.
The above, only this utility model preferably detailed description of the invention, but this utility model
Protection domain be not limited thereto, any those familiar with the art is in this practicality
In the technical scope of novel exposure, according to the technical solution of the utility model and utility model structure thereof
Think equivalent or change in addition, all should contain within protection domain of the present utility model.
Claims (4)
