Abstract
The invention relates to the technology of LED line lamps, particularly to a light distribution device of an LED line lamp. The invention is implemented through the following technical scheme: the light distribution device of the LED line lamp adopts the structure that an arc-shaped raised line is arranged at the middle of a light-receiving surface of the device in the length direction of the device; a plurality of triangular dentiform raised lines are symmetrically arranged on two sides of the arc-shaped raised lines. The light distribution device can effectively improve the light utilization ratio and the projection height, and is uniform in light emission.
Description
Technical field
The present invention 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 patent of invention 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.
Summary of the invention
The light distribution device that the object of this invention is to provide a kind of LED line lamp, it can effectively improve light utilization, improve delivery altitude, and bright dipping is even.
Above-mentioned technical purpose of the present invention 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 invention 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 invention preferred, the exiting surface of this device is plane.
As of the present invention preferred, the exiting surface of this device is cambered surface.
Preferably described triangle dentation raised line is right angle dentation as of the present invention, 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 present invention has following beneficial effect: the present invention is simple in structure, easy to implement; The present invention can adopt the optical plastics such as PC or PMMA, also can be phyllosilicate glass, unique texture of the present invention, 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 present invention 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 present invention than single convex lens thinner thickness, thereby optical energy loss is few, light extraction efficiency is high; And the present invention 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%.

Fig. 1 is embodiment 1 structural representation.
In figure, 1, sensitive surface, 11, arcuation raised line, 12, triangle dentation raised line, 2, exiting surface, 3, lamp body, 4, LED light source.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
This specific embodiment is only explanation of the invention; it is not limitation of the present invention; 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 invention, 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 12Wei 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.
