Description
Technical field
The utility model relates to optical lens technical fields, more particularly to a kind of usury for pavement street lamp
With the double spreadlight lenses of rate.
Background technique
Street lamp lens are exclusively used in high-power LED street lamp, are able to cooperate great power LED use because different road have it is different
Optical demands, such as: type (trunk roads, main line, branch, garden cell of the distance between street lamp height, light pole, road
Deng), therefore the angle requirement of street lamp lens is also not quite similar, and in general, conventional list polarisation street lamp, trunk roads light pole height
For 10-12M, light pole is apart 30-35M, symmetry direction angle at 145 ° -155 ° or so, polarization direction and road width with
And the elevation angle of installation is related, generally at 50 ° -80 ° or so.
Conventional street lamp only has side polarisation, i.e., by the light of lamp stand side deviation to road as far as possible, and direction of traffic is pair
Claim light distribution, mounting means is mostly bi-directional symmetrical cloth lamp or two-way cross cloth lamp or unilateral cloth lamp, since pavement is not very
Width, generally 3-4 are meter wide, if two-way cloth lamp is more wasteful, and is laid out unreasonable, are unfavorable for integrated planning, at present people's row
Road lamp mounting means is mostly that diagonal direction respectively fills an exhibition lamp, if that being illuminated with the street lamp of conventionally form, up to not
To good illuminating effect, utilization rate of the light on road is very low, and the irradiation of many light is less than on pavement, and mounting height is opposite
It is shorter, it is general 5-7 meters high, so required polarizing angle is bigger, as shown in Figure 1, the street lamp of existing list polarisation form
Lens both horizontally and vertically equal illumination and uniformity it is all poor, it is lower that illumination is mapped to the brightness on pavement.
Therefore above-mentioned technical problem how is solved, there is very much realistic meaning to those skilled in the art.
Utility model content
The purpose of this utility model is that: in order to solve the street lamp lens of existing single polarisation form both horizontally and vertically
Equal illumination and uniformity it is all poor, illumination is mapped to the lower technical problem of the brightness on pavement, and the utility model provides
A kind of double spreadlight lenses of the high usage for pavement street lamp.
The utility model specifically uses following technical scheme to achieve the goals above:
A kind of double spreadlight lenses of the high usage for pavement street lamp, including double spreadlight lens ontologies, double spreadlight lenses
Body bottom portion offers light inlet, and light source is provided with below light inlet, and light inlet top surface is arc incidence surface, double spreadlight lens sheets
Body top surface is arc light-emitting surface, and arc light-emitting surface is by successively end to end first light-emitting surface, the second light-emitting surface, the 4th light-emitting surface
It is formed with third light-emitting surface, the first light-emitting surface, the second light-emitting surface, third light-emitting surface and the 4th light-emitting surface are free form surface and song
Rate is successively successively decreased, and double spreadlight lens ontologies are connected with light reflecting part, light reflecting part far from one end of the 4th light-emitting surface
Whole arc-shaped, two end of light reflecting part is connected to the second light-emitting surface and third light-emitting surface side, light reflecting part bottom
Portion open up it is fluted, groove close to light inlet one side be reflecting surface, light reflecting part top surface be exit plane, light reflecting part
The angle of two ends is α, α >=90 °.
Further, the angle between reflecting surface and horizontal plane is β, 40 °≤β≤60 °.
Further, reflecting surface is free form surface.
Further, the material of double spreadlight lens ontologies and light reflecting part is transparent PC or PMMA.
Working principle: the light that light source issues is reflected by arc incidence surface, and a part of light directly goes out from arc
Smooth surface is gone out, this some light is largely distributed in the 4th light-emitting surface direction (i.e. main polarisation region) of double spreadlight lens ontologies,
In rest part light refraction to reflecting surface, go out again from exit plane after light is reflected, the light gone out from exit plane
Also towards the 4th light-emitting surface direction of double spreadlight lens ontologies, so that the light that this part wastes rationally be used.
The beneficial effects of the utility model are as follows:
1, the light that light source issues is reflected by arc incidence surface, due to the first light-emitting surface, the second light-emitting surface, third
Light-emitting surface and the 4th light-emitting surface are free form surface and curvature is successively successively decreased, and light is mainly lesser towards arc light-emitting surface curvature
Position reflects away, i.e., a part of light is directly gone out from the second light-emitting surface, third light-emitting surface and the 4th light-emitting surface, this part light
Line is largely distributed in the region of the main polarization direction of double spreadlight lens ontologies, will in rest part light refraction to reflecting surface
It goes out again from exit plane after light reflection, since light reflecting part is the 4th light-emitting surface that double spreadlight lens ontologies are arranged in
The reverse position (i.e. non-polarized region) in (i.e. main polarisation region), and light reflecting part is integrally arc-shaped, light reflecting part head and the tail
The angle at both ends is a, and a >=90 °, overlay area is wide, therefore reflecting surface can close this some light for being refracted to non-polarized region
Reason uses, and the light exhaled by the utility model is in the both horizontally and vertically equal illumination of (i.e. double polarisations) and uniformly
Property is all relatively good, improves the brightness that illumination is mapped on pavement, practical.
2, the angle between reflecting surface and horizontal plane is β, 40 °≤β≤60 °, is experimentally confirmed, by reflecting surface inclination angle
Degree is arranged between 40 ° -60 °, the light for being largely refracted to reflecting surface can be reflected into exit plane, can reach use and want
It asks.
3, reflecting surface is free form surface, and optical lens with free curved surface has bigger face type freedom degree, meets optical design
It is theoretical.
