Used as preferred scheme of the invention, also including lens, the lens are arranged on light guide side or and light guide
Setting is integrated, for receiving the light that the light guide is projected, and final adjustment far lighting light field distribution.
Used as preferred scheme of the invention, the light guide is integrated with ray-collecting part, more compact structure, more excellent
Change, reduce the cooperation technique between multiple parts, light guide effect more easy to control.
Used as preferred scheme of the invention, the ray-collecting part is lens body.
Disclosed herein as well is a kind of far lighting device, it includes：
The guiding device；
Light source part, the light of the ray-collecting portion collection is the light that the light source part sends；
By setting distinctive light guide, after the light for sending light source part is collected, light can be expanded in short distance
The radial direction bore of line, can thus realize shortening while the radial direction bore of light is expanded the length of far lighting system,
More save the space hold of far lighting system；
Meanwhile, as described in the background art, Laplace invariant n*H*sin θ（Wherein n is refractive index, and H is off-axis radial height, θ
It is axial angle）It is definite value invariant；For selected LED light source, the luminous size and lighting angle of light source are distributed
It has been determined which part projects the light of near axis area, the application structure can increase the radial direction of light in short distance
