Description
Technical background
The utility model relates to lighting technical field, particularly relates to one and can be used for a kind of optical lens of car light optical design.
Background technology
Along with the rise of the industry of LED, LED is applied to all trades and professions widely.Because the light distribution of LED is approximate Lang uncle cosine radiator, in order to meet different user demands, need to carry out secondary optical design to LED.
The advantages such as because LED has specular removal, the life-span is long, and volume is little, in automobile industry, LED starts to replace conventional bulb gradually and becomes the main stream light sources designed for car light.In car light industry, especially taillight, special moulding and visual effect are more and more subject to the attention in market and the welcome of consumer, one has science and technology sense, the automobile tail light of fashion, the especially ten thousand people focus of gazing at, but in actual automobile lamp design, have defined to the size of position lamp, namely light-emitting area must not be less than 12.5mm
2if TIR lens are relied on to carry out design vehicle Rear Position Lamp simple, its area is difficult to meet the requirement of automobile relevant laws and regulations, and in most of Energy distribution of angle light intensity within ± 5 degree, so little dispersion angle is the regulation that cannot meet automobile lamp, therefore, the problem solving this class seems particularly important.
Utility model content
For the deficiencies in the prior art, the utility model utilizes optically focused collimation property and the optical total-reflection principle of TIR lens, for automobile tail light design, to provide one to produce visual effect uniform, a kind of LED light lens of a plurality of donut, and on the basis of a kind of LED light lens of the present utility model, increase some scattering materials, or other optical lenses, light fixture and the visual effect of various moulding can be derived.
In order to solve the problem, the utility model provides a kind of LED light lens, include LED concentrator section, coupling part and light splitting part, the centre of described LED concentrator section and light splitting part is provided with coupling part, the two linked together by coupling part, described LED concentrator section is made up of TIR lens, and described spectrum part is divided into and has center cone core structure, and profile is stair-stepping rotary body, described coupling part is cylinder.
Further improvement is: increase before the LED light lens of finished product and have a layer thickness to be the scattering material of 2mm.
Further improvement is: described LED light lens form the structure of an integral type by LED concentrator section, coupling part and light splitting part.
Further improvement is: the number of rings that the utility model LED light lens produce visual effect can be realized by the ladder quantity changing light splitting portion outboard, and the width of single annulus also can be realized by the width revising ladder simultaneously.
The beneficial effects of the utility model are: LED light lens of the present utility model high efficiencyly can utilize the luminous energy of LED, the efficiency of light energy utilization can reach more than 90%, the light sent by LED by being provided with LED concentrator section carries out collecting and collimating, via light splitting part for changing light going direction, passing through to increase some scattering materials, or other optical lenses, can derive light fixture and the visual effect of various moulding.The utility model achieves a kind of a plurality of, brightness uniformity, concentric circular visual effect, has the automobile lamp of science and technology sense and stylishness, has certain expanded beam capabilities, can meet the requirement of automobile lamp to light-emitting area.

Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with embodiment, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to the utility model protection domain.
As shown in Figure 1, 2, 3, present embodiments provide a kind of LED light lens, include LED concentrator section 1, coupling part 2 and light splitting part 3, the centre of described LED concentrator section 1 and light splitting part 3 is provided with coupling part 2, the two linked together by coupling part 2, described LED concentrator section 1 is made up of TIR lens, and described light splitting part 3 is for having center cone core structure, and profile is stair-stepping rotary body, described coupling part 2 is cylinder.Increase before the LED light lens of finished product and have a layer thickness to be the scattering material of 2mm.Described LED light lens form the structure of an integral type by LED concentrator section 1, coupling part 2 and light splitting part 3.
The number of rings that the utility model LED light lens produce visual effect can be realized by the ladder quantity changing light splitting portion outboard, and the width of single annulus also can be realized by the width revising ladder simultaneously.
The light sent by LED collimates through LED concentrator, then through taper light splitting surface, scatters to surrounding, again via fully reflecting surface, the light scattered to surrounding changes direct of travel again, is collimated outgoing, wherein intracardiac sidepiece is divided into pyramidal structure, and outside is stepped construction.Expanding of light can be realized by such structure, change Light distribation, also can realize visually uniform, the effect of a plurality of donut.
LED light lens of the present utility model high efficiencyly can utilize the luminous energy of LED, the efficiency of light energy utilization can reach more than 90%, the light sent by LED by being provided with LED concentrator section carries out collecting and collimating, via light splitting part for changing light going direction, passing through to increase some scattering materials, or other optical lenses, can derive light fixture and the visual effect of various moulding.The utility model achieves a kind of a plurality of, brightness uniformity, concentric circular visual effect, has the automobile lamp of science and technology sense and stylishness, has certain expanded beam capabilities, can meet the requirement of automobile lamp to light-emitting area.
