Abstract
The invention provides an even-intensity light guide strip which comprises a light source and a light guide strip body. The light source is disposed at one end of the light guide strip body. Diffuse reflection rings are disposed in the light guide strip body. The circle center of each diffuse reflection ring is located on the axis of the light guide strip body. The diameter of the diffuse reflection rings increases along with the increasing of the distance between the diffuse reflection rings and the light source. A transparent dull polished coating is disposed on the surface of each diffuse reflection ring. Due to the fact that the diffuse reflection rings different in diameter are disposed in the light guide strip body and the diameter of the diffuse reflection rings gradually increases along with the increasing of the distance between the diffuse reflection rings and the light source, the area of the diffuse reflection rings at far end is increased, the lighting strength of the far end, away from the light source, of the light guide strip is enhanced, and lighting evenness of the light guide strip is kept.
Description
Affiliated technical field
The present invention relates to lighting apparatus field, especially, is a kind of leaded light even strong light-strip uniformly.
Background technology
Traditional light-strip generally adopts one end that the mode of light source is set, the light that light source produces is slanted through light-strip, light in light-strip with reflection mode in light-strip internal transmission, in transmitting procedure, part light produces refraction in reflection, light after refraction penetrates described light-strip and forms illuminating ray, and this kind of refracted ray is because the diffuse reflection that light-strip surface smoothing produces is few, therefore be merely able to can see stronger light source in the direction of catering to refraction angle, it can also be seen that from above, light-strip is far away apart from light source, in light-strip, the light intensity of outer transmission all successively decreases.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of even strong light-strip, the uniformity that this even strong light-strip can keep light-strip to emit beam.
The technical solution adopted for the present invention to solve the technical problems is:
This even strong light-strip comprises light source and light-strip, described light source is arranged on one end of described light-strip, in described light-strip, be provided with the diffuse reflection ring of the center of circle on described light-strip axis, described diffuse reflection ring is by the length that increases diameter with the increase of described light source distance, and described diffuse reflection ring surface is provided with transparent frosted coating.
As preferably, the light that described light source sends is directional light.
As preferably, the incident end of described light-strip is provided with transparent diffuse reflection coating.
As preferably, the ring body of described diffuse reflection ring is made up of optical fiber.
The invention has the advantages that:
By the different diffuse reflection ring of diameter is set in described light-strip, and the described light source of keeping at a distance diffuse reflection ring diameter far away increases progressively, make the diffuse reflection articulating of far-end receive the area change of light, reach and supplement the intensity of illumination of light-strip from light source far-end, kept light-strip to send out uniformity of light.
Brief description of the drawings
Fig. 1 is the structural representation that even strong light-strip sends directional light.
Fig. 2 is the structural representation that even strong light-strip sends non-parallel light.
Fig. 3 is the structural representation of even strong light-strip diffuse reflection ring.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
In the present embodiment, consult Fig. 1, this even strong light-strip comprises light source 100 and light-strip 200, described light source 100 is arranged on one end of described light-strip 200, in described light-strip 200, be provided with the diffuse reflection ring 300 of the center of circle on described light-strip 200 axis, described diffuse reflection ring 300 is by the length that increases diameter with the increase of described light source 100 distances, and described diffuse reflection ring 300 surfaces are provided with transparent frosted coating 310.
Above-mentioned even strong light-strip, the light that described light source 100 sends is directional light, consult Fig. 1 and Fig. 2, directional light can make described diffuse reflection ring 300 accurately receive the light from light source, because the medium light transmission of light-strip 200 is not very, therefore this transmission meeting in light-strip of light decays along with the increase of distance, therefore from the diffuse reflection ring 300 of described light source 100 far-ends because of diameter compared with the area that receives greatly light source more greatly to compensate the decay of far-end light.
In another embodiment, the incident end of described light-strip 200 is provided with transparent diffuse reflection coating, described diffuse reflection coating can make the light angle of incident light-strip 200 different, light is shuttled back and forth and diffuse reflection ring 300 described in incident at described diffuse reflection ring 300 uniformly, reduce Fig. 2, shown light cannot uniform fold described in the situation of diffuse reflection ring 300.
Consult Fig. 3, the ring body 320 of described diffuse reflection ring 300 is made up of optical fiber, and described optical fiber can make to see through light that frosted coating 310 enters in it and be distributed to uniformly whole ring body 320, and the light that makes again to reflect ring body 320 is even.
The operation logic of above-mentioned even strong light-strip:
By at the interior different diffuse reflection ring 300 of diameter that arranges of described light-strip 200, and the described light source 100 of keeping at a distance diffuse reflection ring 300 diameters far away increase progressively, make the diffuse reflection ring 300 of far-end receive the area change of light, reach and supplement the intensity of illumination of light-strip 200 from light source 100 far-ends, kept 200 uniformities of light of light-strip.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
