Abstract
The utility model discloses a rectangular hot spot forming device of an LED street lamp, which is used on an LED street lamp with at least one LED chip (1). a light guiding base (2) and a light outlet mirror (3) are arranged in front of the LED chip (1) in order and are integrated, the light outlet mirror (3) is in an elongated ellipse, the end face (31) of the light outlet mirror (3) is a paraboloid, left and right end face (32) is a non-spherical lens. According to the utility model, the luminescent angle of the light fixture is offset to obtain uniform rectangular hot spots, moreover, based on the pavement requirement, the lamp distance and the lamp height can be reasonably designed, no shadow appears between adjacent hot spots, in this way, a bright rectangular light belt with homogeneous luminance is formed on the pavement, no local dark region is formed on the pavement, and the lighting utilization ratio for the pavement is improved.
Description
Technical field
The utility model belongs to technical field of lighting fixtures, relates in particular to a kind of LED street lamp.
Background technology
Because the continuous development of LED technology, so led chip is applied to street lighting in a large number.In existing road lighting technology, the road Lighting Design that has adopts the normal distribution of wide-angle circumference, the road Lighting Design that has adopts unilateral illumination, these two kinds of distribution curve fluxs that design all is conventional light source do not have rational luminous intensity distribution band, all can cause the waste of local light source, perhaps can cause the local dark area on road surface, this not only causes energy waste, and also travelling to vehicle at night makes troubles, and produces potential safety hazard.The applicant's a patent (patent name: the formation device of LED street lamp rectangular light spot, the patent No.: the formation device of having introduced a kind of LED street lamp rectangular light spot ZL200820050262.9), its utilization raster-like non-spherical lens array and non-spherical lens come the light that the LED lamp sends is adjusted as optical system, make the irradiation hot spot of LED lamp produce the rectangle effect, but raster-like non-spherical lens array in this patent and non-spherical lens are made complicated, are difficult to guarantee the rectangle effect of hot spot.
The utility model content
Technical problem to be solved in the utility model provides a kind of light collecting device simple, reliable for effect of making, and it can make the LED street lamp produce the luminous intensity distribution band of rectangle.
The technical solution of the utility model is: a kind of formation device of LED street lamp rectangular light spot, the LED street lamp that is used at least one led chip, set gradually the leaded light seat in the place ahead of led chip and go out light microscopic, light seat and go out light microscopic and fuse, going out light microscopic is microscler ellipticity, its end face is parabolic, and its left and right sides end face is a non-spherical lens.
The axis in bright dipping border and the optical axis coincidence of led chip.
Principle of the present utility model is, when the light that the LED lamp sends goes out by the bright dipping mirror, the light of the parabolic outgoing by going out light microscopic will reflect by miter angle, and the light of the aspheric surface outgoing by going out the light microscopic two ends will be by 120 degree angles refractions.Like this, when light is injected from leaded light seat one side, when penetrating, can form the hot spot of rectangle from going out light microscopic one side.
The beneficial effects of the utility model are, when it is applied on the road lamp, the lighting angle of light fixture is offset, obtains rectangular uniform light spots, and can require design according to the road surface, the length-width ratio that makes rectangular light spot is 1: 2 to 1: 3, appropriate design lamp distance and lamp height make between the adjacent spots shade can not occur simultaneously, can form a uniform rectangle light belt of bright illumination like this on the road surface, can not cause the local dark area on road surface, promote the illumination utilization rate in roadside.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
The specific embodiment
As shown in the figure, the formation device of the utility model LED street lamp rectangular light spot, the LED street lamp that is used at least one led chip 1, set gradually leaded light seat 2 in the place ahead of led chip 1 and go out light microscopic 3, leaded light seat 2 and go out light microscopic 3 and fuse, go out light microscopic 3 and be microscler ellipticity, its end face 31 is parabolic, and the left and right sides end face 32 that goes out light microscopic 3 is non-spherical lens.
After selecting the led chip 1 of typing for use, the side at the led chip 1 of each location is provided with the utility model, and a side that will the utlity model has leaded light seat 2 is provided with the optical axis coincidence of its axis and led chip 1 near led chip 1.
Claims (2)
1. the rectangular light spot of a LED street lamp forms device, the LED street lamp that is used at least one led chip (1), it is characterized in that: set gradually leaded light seat (2) in the place ahead of led chip (1) and go out light microscopic (3), leaded light seat (2) and go out light microscopic (3) and fuse, go out light microscopic (3) and be microscler ellipticity, its end face (31) is parabolic, and its left and right sides end face (32) is a non-spherical lens.
2. the rectangular light spot of LED street lamp according to claim 1 forms device, it is characterized in that: the axis in described bright dipping border and the optical axis coincidence of led chip.
