Abstract
The utility model provides a lens for an LED road lamp, the lens can incline a light towards an effective use region, so that light utilization rate is improved, and the light on the road is more practical. The LED road lamp lens includes an incidence surface, a light emitting surface and a bottom surface, the incidence surface, which is a quadric surface, is located at a middle part of the bottom surface, the light emitting surface is a deformed aspheric surface, and a surface coefficient Kx of the light emitting surface is not less than a range from -0.8 to -10, and Ky is equal to a range from 0.2 to 0.4, wherein the Kx is a cone factor in X-axis direction, and the Ky is a cone factor in Y-axis direction. In the LED road lamp lens, the a light emitting direction of the LED is constrained by the incidence surface and the light emitting surface of the lens, so that a lighting region of the lamp forms a rectangular uniform lighting surface, demands on light distribution, illumination and uniformity of city road lighting are satisfied, and the LED road lamp lens can be widely used for an integrated high-power LED having a large light emitting surface.
Description
Technical field
The utility model relates to a kind of LED street lamp lens.
Background technology
At present, just extremely people's favors of advantage such as the LED street lamp is low with its energy consumption, life-span length, non-secondary pollution, especially in the today of advocating green illumination, but because high-power LED light source sends is circular light field, its light distribution of 85% is in the central area, very fast in the radial direction decay, this just needs to adopt corresponding optical system luminous intensity distribution again.The light-configuration mode of existing comparative maturity is to lay optical lens before led light source, and lens adopt symmetric design, but because of street lamp post generally is arranged on the roadside, be mapped to road zone in addition so in use have a large amount of illumination, be unfavorable for effective utilization of luminous energy, also can cause " light pollution " The Surroundings in Cities.
The utility model content
Technical problem to be solved in the utility model provides the lens that a kind of LED street lamp is used, and these lens can make light to effective use regional dip, improves the utilization rate of light, and the light that is radiated on the road is more corresponded to actual needs.
The technical scheme that the utility model technical solution problem is adopted is: the LED street lamp lens, comprise incidence surface, exiting surface and bottom surface, described incidence surface is positioned at the middle part of bottom surface, described incidence surface is a quadratic surface, and described exiting surface is an anamorphic aspherical surface, the curved surface coefficient of described exiting surface: Kx＞=-8～-10, Ky=0.2～0.4, wherein, the axial circular cone coefficient of Kx:X, the axial circular cone coefficient of Ky:Y.
The beneficial effects of the utility model are: the incidence surface of scioptics and exiting surface retrain the light direction of LED, make its field of illumination become a rectangular uniform illuminated area, meet light distribution and the illumination and the uniformity requirement of city illumination; According to the actual demand of street lamp, obtain uniform illuminated area by the incidence surface of control lens and the eccentric distance of exiting surface, significantly improve the utilization rate of luminous energy, the utility model can be widely used in the integrated high power LED of big light-emitting area.

The specific embodiment
As shown in Figure 1-Figure 3, LED street lamp lens of the present utility model comprises incidence surface 1, exiting surface 2 and bottom surface 3, and incidence surface 2 is positioned at 3 middle parts, lens bottom surface, and incidence surface 1 is a quadratic surface, i.e. ellipsoid; Exiting surface 2 is anamorphic aspherical surfaces, the curved surface coefficient of exiting surface 2: Kx=-8～-10, and Ky=0.2～0.4, wherein, the axial circular cone coefficient of Kx:X, the axial circular cone coefficient of Ky:Y.The eccentric distance Δ of incidence surface 1 and exiting surface 2 is 3～6 millimeters, incidence surface 1 deflection pavement one side.Distance between incidence surface 1 and exiting surface 2 summits is that the center thickness of LED street lamp lens is 6～10 millimeters.
Be provided with installation base 4 in the left and right sides of said lens bottom surface 3, be used for being connected of lens and light fixture.Bottom surface 3 is same plane with the LED installed surface, to guarantee the relative position between LED and the lens.Lens can adopt materials such as PMMA, PC or glass to make, and adopt integrative-structure.
From Fig. 1, length of lens direction of the present utility model is greater than 65 millimeters, and width is greater than 52 millimeters.
The utility model can use exiting surface to be of a size of the integrated high power LED of 22X22 millimeter, 22X16 millimeter, 16X16 millimeter or 10X10 millimeter.After integrated high power LED installed, it went out the incidence surface 1 of optical position over against the LED street lamp lens.The projection scope of lens of the present utility model is big, under the high 12 meters situation of lamp, can shine the rectangular area of 40X19 rice.When the high reduction of lamp, the projected area dwindles in proportion, and when the lamp height raise, amplified in proportion the projected area.Integrated high power LED is through lens of the present utility model good evenness behind the luminous intensity distribution again, uniformity of illuminance＞0.8 in zone, middle rolling car road, above-mentioned rectangular area, the wherein vertical uniformity＞0.5.
The curve of light distribution of lens of the present utility model as shown in Figure 4, it has reflected that light that LED sends is after lens refraction of the present utility model, shape at the pairing light intensity in different beam angles position and the curve of light distribution, among the figure, concentric ring is represented the size of light intensity, homocentric rays is represented the irradiating angle of light, after the curve of batswing tab shape represents that light is through the lens refraction, along road irradiating angle longitudinally, zone and corresponding light intensity, after the fruit stone pattern curve at center represents that light is through the lens refraction, along road horizontal irradiating angle zone and corresponding light intensity.As can be seen from the figure, it is wing that vertical curve of light distribution is bat, and beam angle is 135 degree.
