Abstract
The invention provides a street lamp lens which comprises a reflector and a lens body. The lens body is a recessed curve face. A recessed reflecting area which is communicated with the curve face and used for mounting the reflector is formed on one side of the curve face. Reflecting and refracting principles are utilized, the reflector is designed in coordination with lens curvature, distributed lighting effect of LED secondary distribution light is increased, light is evenly radiated on a main road, and the main road is allowed to be brighter under the same energy consumption or power consumption is lower at the same main road lighting degree.
Description
Technical field
The invention belongs to street lamp and manufacture field, be specifically related to a kind of street lamp lens realizing quadratic distribution light.
Background technology
Because different road has different optical demands, such as: the kind (trunk roads, main line, branch road, garden community etc.) of the distance between street lamp height, light pole, road, therefore the angle requirement of street lamp lens is also not quite similar.Whether street lamp lens is required of the uniformity of light utilization and optically focused angle and hot spot comparatively speaking, up to standard for the brightness value on road surface, and this is the problem that street lamp producer needs design consideration.
Existing lamp lens areflexia, only has refracted ray to distribute, and major trunk roads cannot be allowed brighter.
Summary of the invention
For the defect existed in prior art and deficiency, the present invention proposes a kind of wide-angle street lamp lens with reflector, is mainly used in LED street lamp, realizes the distribution of quadratic distribution light.
In order to achieve the above object, the present invention proposes a kind of street lamp lens, comprising:
Reflection shield and lens, wherein, described lens are the curved surface of indent, described curved surface side be provided be communicated with described curved surface, indent, the reflective areas of settling reflection shield.
Further, described reflection shield is arc or semicircle.
Further, described reflection shield internal layer is reflector layer.
Further, the lateral cross section shape of the transmission plane of described lens is circular or oval.
Further, described lens have two transmission planes.
Further, described street lamp lens also comprises base, and described reflection shield and lens spiral-lock are on described base.
Further, described base installs LED street lamp.
The present invention adopts principle of reflection and refraction principle, utilize the matching design of reflection shield and lens curvature, improve the light efficiency of the distribution of LED quadratic distribution light, make major trunk roads road surface light more even, particularly when same consumption energy, major trunk roads can be allowed brighter.Or when meeting major trunk roads illumination, less electric energy can be consumed.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.For person of ordinary skill in the field, from detailed description of the invention, above and other object of the present invention, feature and advantage will be apparent.
As shown in Figure 1, a kind of street lamp lens of the present invention, comprising:
Reflection shield 2 and lens 1, wherein, described lens 1 are the curved surface of indent, described curved surface side be provided be communicated with described curved surface, indent, the reflective areas of settling reflection shield.Described curved surface comprises multiple transmission plane, and the lens centre axle of described multiple transmission plane is asymmetric.Described lens 1 have two transmission planes, and the lateral cross section shape of described transmission plane is circular or oval.
As shown in Figure 2, in a preferred embodiment, described reflection shield is arc or semicircle, and its internal layer is reflector layer.
Fig. 3 and Fig. 4 respectively illustrates front view and the top view of the street lamp lens that the present invention proposes, preferably, described street lamp lens also comprises base 3, mounted LED lamp on described base, described lens and the reflective areas spiral-lock be communicated with it are on described base, described reflection shield is placed in the space of described reflective areas and base formation, and reflective surface is towards LED.
The present invention adopts principle of reflection and refraction principle, utilizes the matching design of reflection shield and lens curvature, and improve the light efficiency of the distribution of LED quadratic distribution light, the distribution curve flux having the present invention to obtain as shown in Figure 5.
Hot spot figure as shown in Figure 6 can obviously find out, street lamp lens of the present invention can make major trunk roads road surface light more even, particularly when same consumption energy, major trunk roads can be allowed brighter.Or when meeting major trunk roads illumination, less electric energy can be consumed.
The foregoing is only preferred embodiment of the present invention, be not used for limiting practical range of the present invention; If do not depart from the spirit and scope of the present invention, the present invention is modified or equivalent to replace, in the middle of the protection domain that all should be encompassed in claim of the present invention.
