Example 2:
this embodiment is a preferred embodiment of embodiment 1.
In this embodiment, as shown in fig. 1, fig. 4, fig. 5, fig. 6, fig. 7, fig. 8, and fig. 9, the first light source 5 and the second light source 6 both use LED light sources, the incident refraction collimating surface 1, the first incident refraction surface 8, and the total reflection collimating surface 9 together form a first light entering system, the light emitted by the first light source 5 has a light emitting angle of 120 °, the light is refracted from an air medium through the first incident refraction surface 8 and enters a plastic medium, and then the light is totally emitted and collimated by the total reflection collimating surface 9 to obtain parallel light. The light emitted by the first light source 5 is refracted from the air medium into the plastic medium of the wall thickness part 7 through the refraction collimating surface 1 and collimated to obtain parallel light. The light rays emitted by the first light source 5 are all collimated into parallel light rays after entering the plastic medium, and the light ray direction can be controlled better in the follow-up process. The parallel light rays irradiate the total reflection patterned surface on the reflection end 4, namely the first reflection region 41, the total reflection is carried out on the total reflection patterned surface by utilizing the total emission principle, the light rays are further reflected by the patterned surface to generate light ray angle change, the light rays irradiate the total reflection molded surface 3 and then are emitted to an air medium and irradiate a test screen, and the first function is realized.
The second incident refraction surface 2 is a single second light inlet system, as shown in fig. 1, the light emitting angle of the light emitted by the second light source 6 is 120 degrees, the light is refracted from the air medium to enter the plastic medium of the wall thickness member 7 through the second incident refraction surface 2, the light emitting angle is shrunk to a certain degree, and the light can be totally reflected and not refracted when irradiating the total reflection molding surface 3 and then is emitted to the air medium. The light irradiates to the total reflection pattern surface on the reflection end 4, the total reflection is carried out on the total reflection pattern surface by utilizing the total reflection principle, the light is further reflected by the total reflection pattern surface to generate the light angle change, the light irradiates to the total reflection molded surface 3 and then is emitted to the air medium, and the light irradiates to the test screen, so that the second function is realized.
Furthermore, the first light-entering system composed of the incident refraction collimating surface 1, the first incident refraction surface 8 and the total reflection collimating surface 9 has the characteristic of high collimation property, so that the light emitted by the corresponding first light source 5 can be completely changed into collimated light after entering the thick-wall part 7, the utilization efficiency of the light is improved, and the functions with higher requirements on regulation brightness, such as a turn light, a brake light and the like, can be mainly utilized to light the patterned surface of the area corresponding to the first light-reflecting area 41. The second incident refraction surface 2 has a certain radian and has a refraction effect similar to a convex lens on light, the second light inlet system can ensure that the light emitted by the corresponding second light source 6 is narrowed compared with 120 degrees after entering the thick-wall part 7, but a certain diffusion angle is still kept, the uniformity of the part of light is ensured while certain utilization efficiency is improved, and the function of requiring the uniformity of the lighting effect, such as a position lamp and the like, can be mainly utilized, and the main lighting area corresponds to the pattern surface of the second light reflection area 42.
It should be noted that, when two functions are considered to share one thick-wall member 7 system, the ratio of the first light inlet system and the second light inlet system can be adjusted according to actual requirements. The larger the proportion of the first light inlet system is, the higher the utilization rate of the corresponding LED light is, and the higher the system efficiency of the corresponding function is. The larger the proportion of the second light inlet system is, the higher the utilization rate of the corresponding LED light is, the larger the lighting area is, and the better the lighting effect is.
The light rays of the first light source 5 cannot enter the thick-walled member 7 from the second light inlet system because the angle of the light rays emitted by the first light source 5 is 120 °, and the light rays are all utilized by the first incident refraction surface 8 and the total reflection collimation surface 9 and become parallel light to enter the thick-walled member. The light of the second light source 6 will partially enter the thick-walled member 7 through the total reflection collimating surface 9, but will be emitted as stray light on the thick-walled member 7, and will not affect the light-emitting surface of the first light-reflecting region 41.
In practical application, the radian of the second incident refraction surface 2 can be adjusted according to practical effects. If the radian is too small, the light shrinkage of the second light source 6 is not obvious when the second light source is changed into a plane, the light utilization efficiency is very low, and the effect of bright center and dark sides is caused when the second light source is lighted, so that the uniformity is poor. The radian is too large, and the light of the second light source 6 is excessively concentrated, so that all the light is concentrated to the middle point of the total reflection pattern surface, and the effects of excessively bright center, excessively dark two sides and poor uniformity during lighting can be caused. When the radian is moderate, the light can be contracted to the parallel light, or the light has a certain diffusion angle compared with the parallel light, so that the utilization efficiency of the light is ensured, the brightness of the whole lighting area is consistent when the lighting is carried out, and the uniformity of the lighting effect is good.
Compared with the prior art, the space between the two light sources is larger, the thermal performance is more beneficial, and the heat dissipation requirement is smaller. In the prior art, when two light sources work, the work of the LED is unstable or the service life of the LED is influenced due to overheating, a larger heat radiator is needed to help heat dissipation, and the cost is increased. The first and second light reflecting regions 41 and 42 in fig. 1 can be simultaneously turned on when functioning as a stop lamp and a position lamp, whereas the configuration in fig. 3 can only be turned on for one function at a time.
Furthermore, the first light reflecting area 41 and the second light reflecting area 42 in the present invention can be controlled to be turned on separately, so that the individuation of the vehicle lamp can be increased, and meanwhile, the patterns of the first light reflecting area 41 and the second light reflecting area 42 can be designed separately, so that the structure is more flexible for realizing different functions.
