The specific embodiment
Please refer to Fig. 1 and Fig. 2, it is preferred embodiment stereogram of the present invention and vertical view.This preferred embodiment is a kind of optical fiber light-guiding type car lamp, and it comprises several light source modules 10, several optical fiber 20, a light harvesting cell body 30 and lens 40.
These several light source modules 10 are example with this preferred embodiment, comprise nine LED modules, and each LED module can comprise a pedestal 12 and several LED14, and single LED14 then used in this preferred embodiment, and this LED14 is installed on this pedestal 12; The quantity of these several optical fiber 20 is identical with light source module 10, and this preferred embodiment comprises nine optical fiber 20.
This light harvesting cell body 30 is to be made of a hollow barrel, and its surface is formed with several slotted eyes 32 that connects the hollow barrels, and wherein an end forms the notch 36 of an opening; This light harvesting cell body 30 can be the hollow barrel that a highly reflective metal material (as aluminium, silver) is shaped, or is the inner hollow barrel (as present embodiment) that scribbles a reflecting layer 34, and wherein, this reflecting layer 34 is a highly reflective film, as aluminium, silverskin
Please cooperate with reference to figure 1 and Fig. 5, the cross section of this light harvesting cell body 30 can become Any shape according to Demand Design, and the cross section of this preferred embodiment is to be a pentagon, and this pentagon is by a rectangle and trapezoidal combining, the pentagon that makes formation wherein an interior angle A greater than 180 degree, shown in Figure 1A.
Each light source module 10 all is of coupled connections with an end of an optical fiber 20, and the light that this light source module 10 is produced all can enter this optical fiber 20 and transmit, and the other end of each optical fiber 20 then is of coupled connections with this light harvesting cell body 30 by this slotted eye 32; In addition, 40 on these lens place this notch 36 front ends, and can be according to different optical designs and demand, place on the optical path of output light of this notch 36 and and keep certain distances with this notch 36, wherein, these lens 40 can be a non-spherical lens, Fresnel (Fresnel) lens or spherical lens.
Please cooperate with reference to figure 2 and each light source module 10 of Fig. 3 and the light L that produces is passed to this light harvesting cell body 30 inside by optical fiber 20, because this this reflecting layer 34 of light harvesting cell body 30 inwall coatings, so light repeatedly reflects and forms the light beam L1 of a specific distribution shape in the cell body inwall, and the light beam L1 of this specific distribution shape penetrates and reaches this lens 40 by this notch 36, the light beam L1 of this specific distribution shape passes these lens 40 with after adjusting light path, can obtain an output light L2 in the another side of these lens 40, and the distribution of the light shape of this output light L2 institute projection is a monolateral slightly wide irregular rectangular field of illumination S, light shape wider distribution person is a broadside W, light shape narrow distribution person is a narrow limit T, makes the profile of this illumination light S corresponding with these light harvesting cell body 30 cross-sectional shape; The profile of this field of illumination S and Luminance Distribution then as shown in Figure 3, wherein, if with the brightness in the S of field of illumination the is considered as brightness of etc.ing, then this broadside W is a high light zone because of the light distribution with area broad, this narrow limit T then is a low light level zone.
Please refer to Fig. 4, when our a vehicle C1 that is equiped with this optical fiber light-guiding type car lamp when the arrow direction is advanced, its projection is painted in the field of illumination on road surface, the place ahead S such as dotted line.When the other side one vehicle C2 head-on sails towards we vehicle C1, because S narrow limit T in this field of illumination is near the second vehicle C2, and because this narrow limit T is low light level zone, so the driver of this second vehicle C2 only accepts more weak light irradiation, and our vehicle C1 is owing to have the high light zone of broadside W, so still possess bright illumination light at front region.
Please referring again to Fig. 4, because this optical fiber light-guiding type car lamp is to be passed to this light harvesting cell body 30 by the light L that optical fiber 20 sends light source module 10, so any position that light source module 10 can place automobile body is with away from thermals source such as engine E.
Because the projected light shape of this illumination light output light L 2 is to cross sectional shape that should notch 36, therefore, if needing to form different light shapes distributes, then can control the cross-sectional shape of this notch 36 and the illumination light S of the shape distribution that obtains not share the same light, wherein Fig. 6 is notch 36 schematic diagrames of three kinds of different profiles with Fig. 7.Wherein these notch shown in Figure 6 36 cross sections are a horizontal L font; This notch shown in Figure 7 36 is a rectangle.
In sum, the present invention can obtain required light shape distribution output light by the cross-sectional shape of this light harvesting cell body 30 of control with this notch 36; And, make light in this light harvesting cell body 30 after repeatedly reflecting, reach the homogenising of certain depth because light harvesting cell body 30 inwalls have reflecting layer 34; Simultaneously, light source module 10 can be installed in away from automobile, motorcycle heat source position to overcome the problem that reduces poor heat radiation.
