Abstract
The utility model relates to the technology of LED line lamps, in particular to a light distribution device for the LED line lamps. According to the technical scheme, an arc-shaped protruding strip is arranged in the middle of a light-receiving surface of the light distribution device in the length direction of the light distribution device, and a plurality of peg-tooth-shaped protruding strips are symmetrically arranged on the two sides of the arc-shaped protruding strip. According to the light distribution device for the LED line lamps, the utilization rate of light can be effectively improved, the projection height is increased, and output light is uniform.
Description
Technical field
The utility model relates to LED line lamp technology, particularly a kind of light distribution device of LED line lamp.
Background technology
Light distribution device of the prior art, in the application publication number disclosed a kind of LED wall lamp of utility model patent that is CN102777833A, comprise lamp body, be arranged on a plurality of LED, the lamp outer casing on lamp body and be installed on the end cap at lamp body two ends, described lamp outer casing is fine aluminum section bar; Described end cap is die casting aluminium end cap; Described lamp body surface is through peroxidating or the processing of spraying paint; On described lamp body, be provided with safety glass; Here safety glass is as the light distribution device of this wall lamp bright dipping, and it is poor that it goes out light effect, and light utilization is low, and delivery altitude is also lower.
Utility model content
The purpose of this utility model is to provide a kind of light distribution device of LED line lamp, and it can effectively improve light utilization, improve delivery altitude, and bright dipping is even.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs: a kind of light distribution device of LED line lamp, the sensitive surface middle part of this device has and has the arcuation raised line arranging along this device length direction, and the bilateral symmetry of described arcuation raised line has many triangle dentation raised lines.
As of the present utility model preferred, the crown that is positioned at many described triangle dentation raised lines of described arcuation raised line one side is intensive shape gradually along this device edge to described arcuation raised line direction.
As of the present utility model preferred, the exiting surface of this device is plane.
As of the present utility model preferred, the exiting surface of this device is cambered surface.
Preferably described triangle dentation raised line is right angle dentation as of the present utility model, and described in each in triangle dentation raised line perpendicular to the sidewall of this device sensitive surface comparatively near described arcuation raised line.
In sum, the utlity model has following beneficial effect: the utility model is simple in structure, easy to implement; The utility model can adopt the optical plastics such as PC or PMMA, also can be phyllosilicate glass, unique texture of the present utility model, makes sensitive surface be similar to Fresnel profile, during use, LED luminous point is positioned at the focal position of sensitive surface, and the ray cast of sending as LED is during to sensitive surface, perpendicular to the beam angle of line lamp direction, can converge, thereby the light of effective LED, improve light utilization, meanwhile, also increased the delivery altitude of LED line lamp large; And the utility model is generally tensioning member, in the direction that is parallel to LED line lamp, LED light can not converge, but free mixed light, thereby be conducive to make the even bright dipping on LED line lamp length direction; And owing to being similar to the design of Fresnel profile, make the utility model than single convex lens thinner thickness, thereby optical energy loss is few, light extraction efficiency is high; And the utility model can adopt expressing technique to make, so cost is lower, equipment is compact convenient, has improved the efficiency of producing equipment, and the cost savings of light distribution device reach more than 20%.

Below in conjunction with accompanying drawing, the utility model is described in further detail.
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make to the present embodiment the modification that there is no creative contribution as required after reading this description, but as long as within the scope of claim of the present utility model, are all subject to the protection of Patent Law.
Embodiment 1: as shown in Figure 1, a kind of light distribution device of LED line lamp, during assembling, is fixedly arranged on line lamp housing 3, and LED light source 4 is located on housing 3, and is positioned at the focal position of the present embodiment; The present embodiment is as the light-emitting plate of line lamp, and sensitive surface 1 middle part of the present embodiment has the arcuation raised line 11 arranging along the present embodiment length direction, and the bilateral symmetry of arcuation raised line 11 has many triangle dentation raised lines 12.
The crown of many triangle dentation raised lines 12 that is positioned at arcuation raised line 11 1 sides is intensive shape gradually along the present embodiment edge to arcuation raised line 11 directions; And triangle dentation raised line 12 is right angle dentation, and in each triangle dentation raised line 12 perpendicular to the sidewall of the present embodiment sensitive surface 1 comparatively near arcuation raised line 11.
The exiting surface 2 of the present embodiment is cambered surface.
Embodiment 2: be with the difference of embodiment 1, the exiting surface 2 of the present embodiment is plane.
