Description
Technical field
The utility model is related to a kind of street lamp lens, more particularly to a kind of street lamp of raising type class street lamps curbside utilization rate
Lens.
Background technology
At present, the type street lamps of North America market, for curbside utilization rate requirement more than 80%, for type4-medium points
Cloth, using general design method, although curbside utilization rate can also accomplish almost, but whole lens can be thicker, thoroughly
Mirror size is than larger, and center thickness easily shrinks than larger.Existing polarisation street lamp lens such as patent 201520640479.5 is remembered
Carry, including a side by roadside and the side away from roadside, the side away from roadside is past to be recessed a use
In the storage tank and a reflection groove of the accommodating LED/light source of adaptation, the storage tank is arranged at intervals with reflection groove, and the reflection groove
It is arranged above storage tank, cell wall of the reflection groove close to storage tank side is set to fully reflecting surface.Though such a street lamp lens
Part utilization rate can be so improved, but as knowable to the opticpath figure of accompanying drawing 1, some light is being passed through after being reflected through fully reflecting surface
Easily total reflection travels to backward or opposite side along exiting surface and forms upper polishing when crossing exiting surface.
Utility model content
Exist after light reflects through fully reflecting surface to solve existing street lamp lens and be easily totally reflected edge when by exiting surface
Exiting surface and travel to the defect that backward or opposite side forms polishing, the utility model spy provides a kind of raising type classes
The street lamp lens of street lamp curbside utilization rate.
The technical solution of the utility model is as follows：
Put down a kind of street lamp lens of raising type class street lamps curbside utilization rate, including lens body, the bottom of lens body
The groove for placing LED is offered on face, groove inner wall constitutes incidence surface, and the reverse side of the base plane where incidence surface is light extraction
Reflection groove is offered around being equipped with projection, raised lower surface on face, the outer wall side of lens body, and reflection groove is close to groove
Side cell wall is fully reflecting surface.In this programme, incidence surface of a part of light through groove inner wall enter lens body after through going out
Smooth surface, which is reflected away, is irradiated to ground, and another part light is radiated on fully reflecting surface after entering lens body through incidence surface, passes through
Side of the street lamp close to roadside is mapped to after fully reflecting surface reflection, so as to be refracted on the ground.The setting of fully reflecting surface in this programme
So that all light can shine the effective coverage of road, curbside utilization rate improves 15% or so compared with conventional lenses, and
And lens will not be too thick, beneficial to processing.At the same time, the raised outside for being arranged on lens body, i.e. fully reflecting surface is also disposed at
The outside of lens body, it is more traditional that reflection groove is arranged on for lens body inside, be not in that light reflects through fully reflecting surface
After easily total reflection is traveled to along exiting surface when by exiting surface afterwards to or opposite side form the phenomenon of polishing.
As preferred structure of the present utility model, the raised upper surface is provided with frosted.Frosted sets in this programme
Put and make it that the superposition of light is more uniform.
Further, the raised upper surface is micro-structural.In this programme, raised upper surface causes light for micro-structural
The superposition of line is more uniform.
For the utility model, the raised arc to be set around lens body outer wall is better achieved.
In summary, the beneficial effects of the utility model are：
1st, in this programme, incidence surface of a part of light through groove inner wall is reflected after entering lens body through exiting surface
Go to be irradiated to ground, another part light is radiated on fully reflecting surface after entering lens body through incidence surface, anti-through fully reflecting surface
Side of the street lamp close to roadside is mapped to after penetrating, so as to be refracted on the ground.The setting of fully reflecting surface causes all in this programme
Light can shine the effective coverage of road, and curbside utilization rate improves 15% or so compared with conventional lenses, and lens will not
It is too thick, beneficial to processing.At the same time, the raised outside for being arranged on lens body, i.e. fully reflecting surface is also disposed at lens body
Outside, it is more traditional that reflection groove is arranged on for lens body inside, be not in by going out after light reflects through fully reflecting surface
Easily total reflection travels to the phenomenon that backward or opposite side forms upper polishing along exiting surface during smooth surface.
2nd, the setting of frosted make it that the superposition of light is more uniform in this programme.
3rd, raised upper surface make it that the superposition of light is more uniform for micro-structural.

Embodiment
For the utility model is better achieved, below in conjunction with the accompanying drawings and specific embodiment the utility model is done further in detail
Carefully illustrate, but embodiment of the present utility model is not limited to this.
As shown in Figure 2 and Figure 3, a kind of street lamp lens of raising type class street lamps curbside utilization rate, including lens body 1, thoroughly
The groove 2 for placing LED is offered in the base plane of mirror body 1, the inwall of groove 2 constitutes incidence surface, the bottom where incidence surface
The reverse side of facial planes is exiting surface 3, is offered around being equipped with projection 4, the lower surface of projection 4 on the outer wall side of lens body 1
Reflection groove 5, reflection groove 5 is fully reflecting surface close to the side cell wall of groove 2.In the present embodiment, a part of light is through in groove 2
The incidence surface of wall, which enters to reflect away through exiting surface 3 after lens body 1, is irradiated to ground, and another part light enters through incidence surface
It is radiated at after lens body on fully reflecting surface, side of the street lamp close to roadside is mapped to after being reflected through fully reflecting surface, so as to be refracted
