Background technology
Along with the development of LED lighting engineering, more and more LED that use are as lighting source.When utilizing the LED lamp as road monitoring light filling lighting apparatus, the luminous intensity distribution of traditional LED lamp has following characteristics:
1, do not use secondary optical system, simply utilize the light distribution of LED self to realize the illumination of monitoring light filling;
2, use secondary optical system, utilize lens or reflector to carry out luminous intensity distribution, its luminous intensity distribution is symmetrical luminous intensity distribution of rotation or rectangle wide-angle luminous intensity distribution basically, and the luminous intensity distribution angle of horizontal direction and vertical direction is more or less the same.
The LED lamp that utilization has above-mentioned luminous intensity distribution characteristics carries out the illumination of road light filling, its shortcoming is: its horizontal direction of hot spot that is incident upon on the face to be illuminated of distant place meets the demands, but the vertical direction hot spot is excessive, cause the luminous energy waste, light pollution is serious, and the efficiency of light energy utilization is low, simultaneously, the dazzle that traditional LED lamp secondary optics light distributing system produces is bigger, influences road traffic safety easily.
The utility model content
The purpose of this utility model is to have overcome above-mentioned shortcoming of the prior art, provides a kind of and can produce the hot spot of long narrow bar shaped at face to be illuminated, effectively avoids luminous energy waste, minimizing dazzle, high definition simple and practical, with low cost to monitor LED light filling lamp lens.
In order to realize above-mentioned purpose, high definition monitoring LED light filling lamp lens provided by the utility model have following formation:
This high definition monitoring LED light filling lamp lens, comprise nearly led light source end, led light source end far away and the lens side that is connected this nearly led light source end and led light source end far away, its main feature is, the nearly led light source end surfaces of described lens can be sphere or aspheric surface, the led light source end surfaces far away of described lens is a cylinder, the axis direction of described cylinder can be horizontal direction or vertical direction, and described lens side is inboard light fully reflecting surface.
The led light source end surfaces far away of this high definition monitoring LED light filling lamp lens can be indent cylinder or evagination cylinder.

Fig. 3 is the profiles of high definition monitoring LED light filling lamp lens provided by the utility model along YZ face among Fig. 1.
The specific embodiment
In order more to be expressly understood technology contents of the present utility model, describe in detail especially exemplified by following examples.
See also shown in Figure 1ly, be a kind of embodiment of high definition monitoring LED light filling lamp lens provided by the utility model.Side at this high definition monitoring LED light filling lamp lens 20 is provided with LED lamp 10.As shown in Figures 2 and 3, this high definition monitoring LED light filling lamp lens 20 comprise nearly led light source end 21, led light source end 23 far away and the lens side 22 that is connected this nearly led light source end 21 and led light source end 23 far away, described nearly led light source end 21 surfaces are sphere, described led light source end far away 23 surfaces are the indent cylinder, the axis direction of described indent cylinder is horizontal direction (an XZ face), described lens side is for being the paraboloid of revolution or rotation free form surface, and inboard, lens side is the light fully reflecting surface.On described nearly led light source end 21 surfaces and/or led light source end 23 surfaces far away, be coated with anti-reflection film.
Its luminous intensity distribution of the light that led light source 10 sends is similar to lambertian distribution.Again through lens 20 refractions, another part is directly through lens 20 refractions after its light that sends part process lens side 22 total reflections.Through the luminous intensity distribution after lens 20 refraction is horizontal direction (XZ face) 30 degree angles pencil of ray, vertical direction (YZ face) 5 degree arrow beam of lights, thus be able to form the strip hot spot on a long way off the face to be illuminated, be suitable for the illumination of road high definition monitoring light filling.Form parameter by the nearly led light source end 21 of adjusting lens 20, led light source end 23 far away and lens side 22, can make luminous intensity distribution after lens 20 refraction is that horizontal direction (XZ face) is 20 to spend to the angle pencil of ray of 70 degree, and vertical direction (YZ face) is 5 to spend to the arrow beam of light of 15 degree.
