And on the premise of balanced light energy outgoing is ensured, the side for improving the lamp guide 100 of short size goes out light energy maximization.
Further, the relative side wall of the side wall of the optical rod 100 that multiple optics silk-screens 300 are located is defined as
The exiting surface 102.After the light that the light source 200 sends injects the lamp guide 100, multiple optics silk-screens are reached
300, the light on the surface with multiple optics silk-screens 300 that falls will be scattered to the exiting surface 102, and further
Project from the exiting surface 102.Light falls when the surface with the optics silk-screen 300 of the lamp guide 100 is mapped to
Light on this face will be scattered.Because the exiting surface 102 is made into the cylinder of certain radius, scattering light energy will be by
The exiting surface 102 of arc cylinder is assembled, and light is penetrated in the exiting surface 102, will form the bright band effect of strip.
Due to the presence of the optics silk-screen 300, the light being incident upon thereon can be reflexed to exiting surface 102, be improve
Light utilization efficiency.Additionally, for more remote apart from light source 200, in the phenomenon that the light intensity of 100 interior transmission of the lamp guide successively decreases,
Present embodiment will be not of uniform size for the spacing setting of multiple optics silk-screens 300, i.e., more remote away from luminous source 200, interval is more
Little, on the contrary then bigger, thus the distribution of 102 light ray energy of exiting surface is controlled, make light ray energy uniformly from the exiting surface
102 project, and can realize guide-lighting uniform effect.Further, the spacing change of multiple optics silk-screens 300 follows Bei Sai
The rule of your curve, so as to solve the problems, such as light energy non-rectilinear gradual change in the lamp guide 100, thus, non-rectilinear can be made
The light energy of gradual change reaches the exiting surface 102 when bezier curve arranges multiple 300 optical reflections of optics silk-screen
Light energy is evenly.
The optics silk-screen 300 is white.The lamp guide 100 can be selected as needed with appropriate light transmittance and refraction
The material of rate.The material of the lamp guide 100 can be selected from unorganic glass or lucite, wherein, the optional autohemagglutination of lucite
Methyl methacrylate（PMMA）, high grade of transparency Merlon (PC), high grade of transparency polrvinyl chloride（PVC）, the poly- ammonia of the high grade of transparency
Ester（PU）, high grade of transparency methyl methacrylate（MMA）, high grade of transparency polyethylene（PE）, high grade of transparency poly terephthalic acid second
Diester（PET）Any in.The lamp guide 100 is by injection mold or the bar of extrusion die molding.This reality
Apply in mode, the lamp guide 100 is integrally formed using expressing technique by extrusion die.
In other change embodiments, the lamp guide 100 is not limited to cylinder, but can also be that other are equal
Even elongate configuration.Specifically, as shown in Fig. 5 a～5e, the cross section of the lamp guide 100 can be semicircle, fan-shaped, circle
Any shape in shape, square, trapezoidal, oval and irregular shape.It should be noted that being led with described in Fig. 5 a～5e
Optical wand 100 is illustrated as a example by only having an incidence surface 101, it will be understood that when the lamp guide 100 is two incidence surfaces 101
During structure, equally applicable.The lamp guide 100 no matter which kind of structure selected is both needed to ensure that multiple optics silk-screens 300 are located
The optical rod 100 the relative side wall of side wall, i.e., described light appears 102 for arcwall face, and arcwall face described go out light
Corresponding 300 homonymy of optics silk-screen in the center of circle in face 102, i.e., described exiting surface 102 is for being directed away from multiple light
Learn the direction evagination of silk-screen 300.Thus, scattering light energy accumulating, light could be penetrated by the exiting surface 102 of arcwall face
In the exiting surface 102, the bright band effect of strip can be formed.At the same time, multiple 300 institutes of the optics silk-screen are provided with
The side wall of the optical rod 100 can be plane, naturally it is also possible to for arcwall face as described in the embodiment.
Additionally, in embodiment is changed, such as Fig. 6 a～6c and 7a～7d, the structure of each optics silk-screen 300
Be not limited to rectangle, can also be circle, round dot, square, square dot, circular face, foursquare face, annular face,
The face of triangle, oval face or prismatic.It should be noted that in Fig. 6 a～6c and 7a～7d with the lamp guide 100 only
Illustrate as a example by having an incidence surface 101, it will be understood that when the structure that the lamp guide 100 is two incidence surfaces 101,
Equally applicable.
Further, in embodiment is changed, such as Fig. 8 a～8b, when the optics silk-screen 300 has major axis and short
During axle, or the short axle is parallel to each other with the axis of the lamp guide 100, is not limited solely to the major axis and is led with described
The axis of optical wand 100 is parallel to each other.Herein, major axis refers to the most long axle of the distance of the relative both sides of the optics silk-screen 300, institute
State short axle and refer to the most short axle of the distance of the relative both sides of the optics silk-screen 300, for example, when the optics silk-screen 300
For oval structure when, the major axis refers to the major axis of oval structure, and the short axle refers to the short axle of ellipse.
Due to the presence of the optics silk-screen 300, the light being incident upon thereon can be reflexed to exiting surface 102, be improve
Light utilization efficiency.Additionally, for more remote apart from light source 200, in the phenomenon that the light intensity of 100 interior transmission of the lamp guide successively decreases,
Present embodiment will be not of uniform size for the spacing setting of multiple optics silk-screens 300, and more remote apart from luminous source 200, interval is more
Little, on the contrary then bigger, thus the distribution of 102 light ray energy of exiting surface is controlled, make light ray energy uniformly from the exiting surface
102 project, and can realize guide-lighting uniform effect.Further, the spacing change of multiple optics silk-screens 300 follows Bei Sai
The rule of your curve, so as to solve the problems, such as light energy non-rectilinear gradual change in the lamp guide 100, thus, non-rectilinear can be made
The light energy of gradual change reaches the light energy of the exiting surface 102 when bezier curve arranges the plurality of silk-screen optical reflection
Evenly.
Embodiment of above is only unrestricted in order to technical scheme to be described, although with reference to embodiment of above pair
The present invention has been described in detail, it will be understood by those within the art that, technical scheme can be carried out
Modification or equivalent should not depart from the spirit and scope of technical solution of the present invention.
