Justice.
As Figure 1-Figure 2, the present embodiment discloses a kind of car light, can be applied in each vehicles, such as each friendship
The signal lamps such as position lamp, turn signal, Brake lamp, the fog lamp of logical tool.The car light includes LED light source mould group 1,2 and of guide structure
Decorative circle 3.Wherein, LED light source mould group 1 includes LED light 11, and LED light 11 presses default spacing arrangement arrangement, and presetting spacing is 2mm-
9mm；Guide structure 2 is oppositely arranged with LED light 11, the light-transmissive guide structure 2 that LED light 11 issues；Decorative circle 3 and LED light source
Mould group 1 connects, and guide structure 2 is arranged between LED light source mould group 1 and decorative circle 3.
Compared to the prior art, the car light in the present embodiment arranges LED light 11 according to certain spacing arrangement, and will
11 line space design of LED light in reasonable range, can eliminate granular sensation of the car light under lighting state and from vehicle body side to
Observation can see the defect of dark space, be conducive to the uniformity for improving lighting, improve lighting effect.
As shown in Fig. 2, LED light source mould group 1 includes bracket 12, PCB circuit board 13 and LED light 11, PCB circuit board 13 passes through
Screw is fixed on bracket 12, and LED light 11 is electrically connected with PCB circuit board 13, and the unlatching of LED light 11 is controlled by PCB circuit board 13
And closing.It should be pointed out that the internal circuit between LED light 11 and PCB circuit board 13 and circuit connection from each other are all
It is the state of the art, which is not described herein again.As shown in figure 3, LED light 11 is uniform along the length direction of PCB circuit board 13
Arrangement, and the preferred 2mm-9mm of spacing L1 at 11 center of two adjacent LEDs lamp, the signal function to be realized by car light of design parameter
Energy and guide structure 2 are determined towards the length that 3 direction of decorative circle extends.
As shown in fig. 4-5, guide structure 2 is arranged between LED light source mould group 1 and decorative circle 3, guide structure 2 and LED light
11 require to be accurately positioned, and guide structure 2 that is to say the incidence surface of guide structure 2 close to the surface of LED light 11, with LED light 11
Surface between the preferred 0.4mm-1.5mm of spacing L2, the semiotic function and LED light 11 that design parameter to be realized by car light
Watt level determine, 11 power of LED light is bigger, and calorific value is bigger, if LED light 11 is excessively close apart from guide structure 2, possibility
Cause guide structure 2 to be deformed by thermal softening, and then influences the translucent effect of guide structure 2.
Further, transmission of the light in guide structure 2, according to the total reflection principle of light, from an end-fire of guide structure 2
Enter Ray Of Light, even if guide structure 2 is warp architecture, light can also follow guide structure 2 and project from the other end.The present embodiment
In guide structure 2 is high using light transmittance, transparent PC material, transparent PMMA material or optical glass system that shock resistance is good
At being completed by injection molding or precision instrument and equipment processing and manufacturing, the incidence surface and light-emitting surface of guide structure 2 all can be by polishings
Reason passes through multiple reflections into the light inside guide structure 2, and from external observation car light, car light shines uniform.It may be noted that
It is that the present embodiment uses the heavy wall light pipe with a thickness of 5mm or more, and as guide structure 2, the thickness direction of light pipe is in Fig. 4
The direction of hatching A-A.
Decorative circle 3 can be detachably connected or be integrally formed manufacture with guide structure 2.Guide structure 2 in the present embodiment
