Description of drawings
Comprise that accompanying drawing is for providing the present invention further to be understood, they are included and are constituted the application's a part, and accompanying drawing shows embodiments of the invention, and play the effect of explaining the principle of the invention with this specification.In the accompanying drawing:
Fig. 1 a and 1b show the side view and the front view of optical system according to an embodiment of the invention respectively.
Fig. 2 a and 2b show respectively according to the sketch map of the optical system of two embodiment in addition of the present invention.
Fig. 3 shows the side view of optical system according to still another embodiment of the invention.
Fig. 4 shows and uses a kind of illuminator that comprises redgreenblue of the present invention.
The specific embodiment
Now with embodiments of the present invention will be described by referring to the drawings in detail.
Fig. 1 a and 1b show according to a kind of optical system of the present invention.This system comprises light source module 101 and waveguide module 102.As shown in Figure 1, the light that light source module 101 sends is injected waveguide module 102 from the plane of incidence 103, repeatedly total reflection exit facet 105 ejaculations afterwards of warp between the face 104 and 105 of waveguide module 102.This face 105 is defined as exit facet.
Waveguide module of the present invention can be processed by glass or transparent plastic.The side structure of this waveguide module can be wedge shape, and is as shown in Figure 1, also can adopt other shapes, will describe in detail as following.The effect of this waveguide module mainly is that the light by plane of incidence input is outputed to exit facet equably.Its basic principle is: waveguide is made greater than the medium of air by refractive index, and is inner in waveguide, if light is by on the face 104 or 105, then producing total reflection greater than the angular illumination of the angle of total reflection in Fig. 1.Because field of illumination place face 104 is not parallel with face 105, light whenever experiences primary event on face 105, and incidence angle will reduce when it shone face 104 once more, so experiences after the total reflection of certain number of times outgoing.In other words, light can be by incident angle and its incidence point decision on the plane of incidence from the position of waveguide outgoing.
Shown in Fig. 1 b, waveguide module 102 can be divided into light diffusion zone 106 and field of illumination 107.Light total reflection in light diffusion zone 106 and not outgoing, to reach the purpose of horizontal proliferation light, after light got into field of illumination 107, through multiple attenuation, its incidence angle will be from exit facet (being positioned at the field of illumination) outgoing one by one less than the angle of total reflection.In addition, light diffusion zone 106 also can omit, i.e. just export from exit facet one by one after the light incident waveguide.
In addition, waveguide module of the present invention also can adopt other shapes.For example Fig. 2 a, 2b and 3 show other forms of waveguide module respectively.In fact, the side view of waveguide module can be wedge shape, taper, or other is irregularly shaped, as long as can let the light of different angles export from exit facet one by one.In each accompanying drawing of the application, simple and clear more and clear for making accompanying drawing, the label with identical tail number is all represented corresponding structure.For example, 206 among 106 among Fig. 1 and Fig. 2 b is used to represent the light diffusion zone, though the two shape can be different.
In addition, in the waveguide module, two faces (the for example face 104 and 105 among Fig. 1 a) of total reflection take place can the while or separately as illumination plane, i.e. exit facet.If only using wherein, one side then needs plated film on another side, to guarantee that all light are all from the illumination plane outgoing as illumination plane.
Fig. 3 has used another embodiment of the present invention.In this embodiment, waveguide module is through folding to form first's (light diffusion zone) 306, join domain 308 and second portion (field of illumination) 307 successively.The plane of incidence is positioned at first 306 and exit facet is positioned at second portion 307, and the light of wherein injecting from the plane of incidence of first 306 gets into second portion 307 through reflection in join domain 308, penetrate from exit facet at last.Wherein, can on join domain 308, plate reflectance coating, light is imported second portion 307.This structure can be dwindled the volume of waveguide module, thereby saves the space.In addition, square structure (being that upper and lower surfaces is parallel) also can be adopted with simplified design and manufacturing in the lateral section of the waveguide of light diffusion zone.
In above-mentioned each embodiment, can plate one deck scattering film on the exit facet (illumination plane), make the even scattering of emergent ray, realize floodlighting.Thereby also can plate illumination that one deck prism film makes outgoing to specific direction, realize the effect of spotlight, can also plate other film and realize other all kinds of illuminating effects.
In addition, optical system of the present invention can also comprise the control module that is connected with light source module, in order to regulate the brightness of the light that light source module sends.
Fig. 4 schematically shows and uses a kind of illuminator that comprises redgreenblue of the present invention.This illuminator comprises power supply and control module 401, lens 402-404 and optical prism 405-406.The light source of this system can be made up of (for example laser or LED) one or more light sources, and it can be polychrome or monochromatic source.The angle that lens 402-404 is used to modulate output beam is to adapt to Wave guide system.In the system that a plurality of monochromatic sources are formed, the Light source correction module also comprises proofreaies and correct the aberration that light sources of different colors is produced in waveguide.As shown in the figure, lens 402-404 is used for respectively the laser of red, basket, green three kinds of colors is expanded the effect of restrainting and playing chromatic aberration correction.Optical prism 405-406 is in harmonious proportion three-beam together, thereby realizes illumination among outputing to waveguide module (not shown).The color of waveguide output can be regulated through the output that changes three kinds of light sources is strong and weak by power control system, thereby realizes the illuminator of scalable light and shade and color.
Those skilled in the art can be obvious, can carry out various modifications and modification and without departing from the spirit and scope of the present invention to above-mentioned exemplary embodiment of the present invention.Therefore, be intended to that the present invention is covered and drop in appended claims and the come scope thereof to modification of the present invention and modification.
