Abstract
The utility model discloses an asymmetrical light distribution LED (Light-Emitting Diode) street lamp, which comprises an LED light source plate, wherein a reflector is fixedly arranged on the LED light source plate, and is provided with a polarized light reflecting surface. The asymmetrical light distribution LED street lamp has the advantages that: the reflector is arranged on the LED light source plate, and light rays emitted by an LED light source are deviated to one side of a lane under the reflecting action of the reflector, so that the road illumination light flux utilization ratio of the LED street lamp is increased, and the road surface illumination is further enhanced.
Description
Technical field
The utility model relates to a kind of LED street lamp, and specifically a kind of LED street lamp of asymmetric luminous intensity distribution belongs to LED street lamp field.
Background technology
The distribution curve flux of traditional LED street lamp is the bat aerofoil profile on the road travel direction, thus can make light along the road length direction disperse and shine on the road surface, reach certain road illumination uniformity.Yet on the direction of having a lot of social connections, the distribution curve flux of LED street lamp generally is a symmetrical expression, even lamp stand has the cantilever and the elevation angle, still has the zone of too much irradiate light beyond to the roadside, thereby has the waste of a part of light.
The utility model content
In order to address the above problem; The utility model has designed a kind of LED street lamp of asymmetric luminous intensity distribution; On the led light source plate, reflector is installed; Light through led light source is sent in the reflection of reflector is partial to track one side more, thereby improves the road lighting luminous flux utilization rate of LED street lamp, further improves road illumination.
The technical scheme of the utility model is:
A kind of LED street lamp of asymmetric luminous intensity distribution comprises the led light source plate, is installed with reflector on the described led light source plate, and reflector is provided with the polarisation reflecting surface.
Further, said reflector matches with the led light source of led light source plate.
Further, said polarisation reflecting surface is positioned at one side towards the road track.
Further, said LED street lamp also comprises diffuser.
Change the light path of the light that led light source sends through reflector, make more rays shine track one side that the LED street lamp is installed.Thereby making the LED street lamp is asymmetric luminous intensity distribution on the road width direction, promptly has more rays to shine track one side, and road lighting luminous flux utilization rate is higher, and road illumination is higher.
The reflection of the polarisation reflecting surface through reflector has changed the light path of the light that led light source sends, thereby has made the more rays shine track one side that the LED street lamp is installed, and promptly the luminous intensity distribution of LED street lamp is an asymmetric on the direction of having a lot of social connections.
The advantage of the utility model is: the LED street lamp that a kind of asymmetric luminous intensity distribution is provided; It on the road travel direction rational batswing tab form; On the direction of having a lot of social connections, more be partial to track one side through the light that reflector sends led light source, thereby improve the road lighting luminous flux utilization rate of LED street lamp; Guarantee still some illumination of zone, roadside simultaneously, reach the requirement of road lighting environment ratio.
The pavement of road illumination of LED street lamp that adopts this reflector is than high 2 to 5 luxs of street lamp of no-reflection device, the street lamp of pavement of road uniformity ratio of illuminance no-reflection device high about 5%; Photochromic inconsistent phenomenon can not appear in the hot spot on the road surface; Can not end rapidly at the direction glazed thread of having a lot of social connections, the road surface does not have tangible terminator or dark space.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Fig. 5 is the illumination hot spot figure that is not with the LED street lamp of reflector;
Among the figure: 1-street lamp main body, 2-led light source plate, 3-reflector.
The specific embodiment
Below the preferred embodiment of the utility model is described, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model.
As illustrated in fig. 1 and 2, a kind of LED street lamp of asymmetric luminous intensity distribution comprises: street lamp main body 1, led light source plate 2, reflector 3; Reflector 3 is mounted on the led light source plate 2, with the led light source coupling on the light source board 2; A side that exceeds on the reflector 3 is the polarisation reflecting surface, and the polarisation reflecting surface is one side towards the road track.
As shown in Figure 3, be the distribution curve flux figure of the said LED street lamp of the utility model.The reflection of the polarisation reflecting surface through reflector 3 has changed the light path of the light that led light source sends, thereby has made the more rays shine track one side that the LED street lamp is installed, and promptly the luminous intensity distribution of LED street lamp is an asymmetric on the direction of having a lot of social connections.
As shown in Figure 4, be the road lighting hot spot figure of the said LED street lamp of the utility model, Fig. 5 is the road lighting hot spot figure that is not with the LED street lamp of reflector.Comparison diagram 4 and Fig. 5, can find out light that the LED street lamp of the said asymmetric luminous intensity distribution of the utility model sends more shine road lamp cap towards a side; If the said LED street lamp of the utility model is used for road lighting, then there is more rays to shine track one side, the illuminating light flux utilization rate obviously improves, and pavement of road illumination can obviously improve.
What should explain at last is: the above is merely the preferred embodiment of the utility model; Be not limited to the utility model; Although the utility model has been carried out detailed explanation with reference to previous embodiment; For a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
