The focal position of the light inputting end of special-shaped 2 rear top of light guide backward is arranged in source 1;Special-shaped 2 light inputting end of light guide is collimating structure, quasi-
Straight structure includes the optical surface 24 of the optical surface 1 of the light guide collimation of top and the light guide collimation at rear;Before special-shaped light guide 2
End is light guide light-emitting surface 7 down, is Light-guiding optics tooth 6,6 bottom end of light guide light-emitting surface 7 and Light-guiding optics tooth on rear side of light guide light-emitting surface 7
Connect in angle.7 top of light guide light-emitting surface is light guide reflecting surface 5, and light guide reflecting surface 5 is located on front side of collimating structure.Light LED light
The light in source 1, the LED light source 1 is collimated by the optical surface 1 of light guide collimation and the optical surface 24 of light guide collimation, and
It is totally reflected in light guide afterwards, i.e., when light enters air by lens, when incidence angle is greater than critical angle, light can be all-trans
It penetrates, changes the light direction of propagation, wherein critical angle is arcsin (n2/n1), and n2 is the refractive index of light guide, and n1 is the folding of air
Penetrate rate.Therefore it is propagated in special-shaped light guide 2 when light, after encountering light guide reflecting surface 5, due to the bending angle of light guide reflecting surface 5,
Light is totally reflected, while changing the direction of propagation;After light is incident to Light-guiding optics tooth 6, the Light-guiding optics tooth 6 changes light
Line refraction angle, refraction angle are less than total reflection angle, and light is emitted from light guide light-emitting surface 7.1 quantity of LED light source is 1
It is a;It is white light source.The abnormity light guide 2 is that light guide is once bent to form by horizontal direction to vertical direction, and light
The spacing in the vertical region led, i.e. Light-guiding optics tooth 6, apart from becoming narrow gradually from top to bottom, form the opposite sex to light guide light-emitting surface 7
Light guide.Abnormity 2 material of light guide is polycarbonate.
Light guide is the light guide that a shape is abnormity, and special-shaped light guide 2 is once bent to form by horizontal direction to vertical direction
, and the spacing in the vertical region of special-shaped light guide 2, i.e. Light-guiding optics tooth 6 to light guide light-emitting surface 7 narrow apart from gradually shortening, this
It is to reduce light in special-shaped light guide 2 because reducing the distance of Light-guiding optics tooth 6 to light guide light-emitting surface 7 in special-shaped 2 tail end of light guide
The total reflection number in portion improves the light extraction efficiency of 2 tail end of special-shaped light guide, increases the uniformity of light guide entirety, therefore referred to as different
Shape light guide, meanwhile, pass through concentrator construction (the i.e. optical surface of the optical surface 1 of light guide collimation and light guide collimation of light guide front end
4) 2 combine with light guide reflecting surface 5, shorten the even electrical distance at normal light leading end, so that the output optical zone domain of whole light guide can be with
It is very short, and have and uniformly light effect.By changing the angle of reflecting surface 5, adjustable whole Light-guiding optics toothed portion
Gradient.
By the way that light guide is arranged to special-shaped light guide, the optical surface 24 of optical surface 1 and the light guide collimation collimated by light guide
The efficient cooperation of light and Light-guiding optics tooth 6 that more efficient 1 source of convergence LED light issues, realizes more efficient special-shaped light guide, from
And reach the function of uniform high-efficiency.The structure for having benefited from light guide allows the light emitting region of whole light guide in very short distance
It is uniform with regard to realizing.
