Description
Technical field
It the utility model is related to a kind of novel street lamp lens.
Background technology
Original street illumination light fixture is mainly using types such as sodium vapor lamps, and its power consumption is big, and short life, and maintenance cost is high,
It is unfavorable for environmental protection.Therefore, substitute conventional lamp using LED lamp has turned into inevitable.
LED street lamp would generally set a lens in order to assemble light, but the hot spot of existing lens projects in LED outer cups
For circle, and the luminous intensity between center and periphery differs larger；In addition, needed in a certain direction for some a wide range of
Illumination, and the occasion for needing small range to illuminate on other direction, such as road lighting, require to shine in road extending direction
It is wide to penetrate scope, good illumination effect, angle demand is big；And needed on vertical road direction to being carried out more close to the track in roadside
Effective illumination, the travel risk brought with the debris for preventing pedestrian from crossing or roadside is parked.And common transparent lamp plate
It is high to easily cause light aggregation immediately below light fixture, illumination, other region illumination are low, cause road surface average illumination low and the uniformity
Difference, the illumination of this brightness unevenness, directly affects traffic safety.
Utility model content
The technical problems to be solved in the utility model is to provide one kind and illuminates wide scope, brightness uniformity, can realize reversely
Irradiate the novel street lamp lens on pavement.
To reach above-mentioned purpose, the technical solution of the utility model is：A kind of novel street lamp lens, including body, it is described
The cross section of body in the width direction is curved, and the outer surface of the cross section in the width direction forms plural number from middle part to both sides
Individual ladder, the cross section of the body along its length is arranged in order by a plurality of projections to be formed, each raised including being sequentially connected
Reflecting surface, the first diffusingsurface, the second diffusingsurface, the reflecting surface is provided with reflective material layer, the song of first diffusingsurface
Rate radius is 1.5 ~ 2 times of the radius of curvature of the second diffusingsurface, and the reflecting surface is an inclined plane, through the light of the second diffusingsurface
Line at least 1/3 is irradiated on reflecting surface, and the light of the reflective surface can be with intersecting through the light of the second diffusingsurface.
Preferably, the reflective material layer is reflecting coating or reflective membrane.
Preferably, the surface of each ladder is arcwall face, and the curvature of the arcwall face on each ladder is identical.
Above-mentioned technical proposal has the advantages that：This novel street lamp lens pass through width cross section, length side
Setting to cross section, realize distributing for a wide range of light, it is wider to enable to illuminate scope, irradiation brightness evenly, and energy
Enough realize that emphasis covers road surface, additionally it is possible to reversely irradiate pavement in passing, basic lighting demand is provided for pavement；Further
, reflective material layer can be reflecting coating, or reflective membrane, reflective membrane can use the 3M reflective membranes of superpower level；Enter
One step, the surface of each ladder is arcwall face, and the curvature of the arcwall face on each ladder is identical, so can preferably realize light
Distribute, raising illuminate scope, there is provided uniform irradiation brightness.
Brief description of the drawings
Fig. 1 is the cross section structure schematic diagram of this lens in the width direction；
Fig. 2 is the cross section structure diagram at A-A in Fig. 1；
Fig. 3 is the structural representation of Street Light Illumination scope.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Referring to figs. 1 to shown in Fig. 3, the present embodiment provides a kind of novel street lamp lens, including body 1, and the body 1 is along width
Spend that the cross section in direction is curved, the outer surface of the cross section in the width direction forms a plurality of ladders 2 from middle part to both sides,
The surface of each ladder 2 is arcwall face 21, and the curvature of the arcwall face 21 on each ladder 2 is identical.The body 1 is along its length
Cross section is arranged in order by a plurality of raised 3 and formed, each raised 3 reflectings surface 31 for including being sequentially connected, the first diffusingsurface 32, the
Two diffusingsurfaces 33, the reflecting surface 31 are provided with reflective material layer, and the reflective material layer is reflecting coating.First diffusion
The radius of curvature in face 32 is 1.5 ~ 2 times of radius of curvature of the second diffusingsurface 33, and the reflecting surface 31 is an inclined plane, through the
The light at least 1/3 of two diffusingsurfaces 33 is irradiated on reflecting surface 31, the light that the reflecting surface 31 reflects can with through second
The light of diffusingsurface 33 intersects.
In Fig. 2, double dot dash line be light project, reflection move towards signal；In Fig. 3, double dot dash line is street lamp vertical cross-section
Light irradiation covering signal on direction.
This novel street lamp lens realize a wide range of light by the setting of width cross section, length direction cross section
Distribute, enable to illuminate that scope is wider, and irradiation brightness evenly, and can realize that emphasis covers road surface, additionally it is possible in passing
Reversely irradiation pavement, basic lighting demand is provided for pavement；Further, reflective material layer can be reflecting coating,
Can also be reflective membrane, reflective membrane can use the 3M reflective membranes of superpower level；Further, the surface of each ladder is arcwall face,
And the curvature of the arcwall face on each ladder is identical, distributing for light so can be preferably realized, scope is illuminated in raising, there is provided uniformly
Irradiation brightness.
It the above is only one preferred embodiment of the utility model, those skilled in the art is made equivalent by claim
Change the protection domain for both falling within this case.
