All falling within the scope of the present invention.
Example 1
The dual-function multiplexing thick-wall optical system following modeling, as shown in fig. 1-13, includes a first light source 1, a second light source 2, a first thick-wall member 7, a second thick-wall member 8, an optical input system, and a PCB 10. The light emitting angle of the first light source 1 and the light emitting angle of the second light source 2 are 120 degrees, the first light source 1 and the second light source 2 are respectively connected to the PCB 10, the first light source 1 corresponds to the second thick-walled member 8, the second light source 2 corresponds to the first thick-walled member 7, and a gap is formed between the first thick-walled member 7 and the second thick-walled member 8. The light inlet system is respectively connected to the first thick-wall part 7 and the second thick-wall part 8 and comprises an incident refraction collimating surface 3, an incident refraction collimating surface 4 and a total reflection collimating surface 5, the outer side of the incident refraction collimating surface 3 is connected with the incident refraction collimating surface 4, and the outer side of the incident refraction collimating surface 4 is connected with the total reflection collimating surface 5. And a second light-emitting pattern surface 9 and a second total reflection step surface 12 are respectively arranged on two sides of the second thick-wall part 8, and the second total reflection step surface 12 is connected with a light inlet system of the second thick-wall part 8. Two sides of the first thick-wall part 7 are respectively provided with a first light-emitting pattern surface 6 and a first total reflection step surface 11, and the first total reflection step surface 11 is connected with a light inlet system of the first thick-wall part 7. The first total reflection step surface 11 and the second total reflection step surface 12 are step-shaped, preferably, the first total reflection step surface 11 and the second total reflection step surface 12 are vertical step-shaped, the first total reflection step surface 11 and the second total reflection step surface 12 form an angle of 45 degrees with the horizontal plane, preferably, the angle between the first total reflection step surface 11 and the second total reflection step surface 12 and the vertical plane is 45 degrees, light rays in the vertical direction in a thick-wall part can be transmitted in parallel along the horizontal direction after being totally reflected for 90 degrees, the light rays are transmitted in parallel along the horizontal direction, and the follow-up better light ray control according to requirements is facilitated. The light rays emitted by the first light source 1 or/and the second light source 2 are finally emitted into the air through the total reflection of the second total reflection step surface 12, so that a multiplexing system is formed.
As shown in fig. 11 to 12, the first light emergence pattern surface 6 is stepped, and preferably, the first light emergence pattern surface 6 is vertically stepped. And the angle between the first light-emitting pattern surface 6 and the vertical plane is less than 45 degrees, the total reflection of the first total reflection step surface 11 is destroyed, so that the light emitted from the first light-emitting pattern surface 6 is refracted into the air, the angle of the light refracted into the air is slightly deflected upwards, when the light enters the second total reflection step surface 12 of the second thick-wall part 8, the light is refracted, the angle of the refracted light is changed once again, and the light is continuously transmitted in parallel along the horizontal direction in the second thick-wall part 8. And the heights of the bottom surfaces of the first light-emitting pattern surface 6 and the second total reflection step surface 12 are consistent, but the height of the upper edge of the first light-emitting pattern surface 6 is greater than that of the upper edge of the second total reflection step surface 12, so that the area of the first light-emitting pattern surface 6 is greater than that of the second total reflection step surface 12, more light rays emitted from the first light-emitting pattern surface 6 are utilized and enter the second total reflection step surface 12 to the maximum extent, and the light ray utilization efficiency is improved. And each step-shaped surface of the first light-emitting pattern surface 6 has a radian.
Both the first total reflection step surface 11 and the second total reflection step surface 12 are of a total reflection property, and the first light exiting pattern surface 6 is of a refractive property. The first light-emitting pattern surface 6 is a vertical step, and is easy to be optically matched with the second total reflection step surface 12 which is a vertical step. Meanwhile, the second light-emitting pattern surface 9 adopts grid-shaped patterns, and the light type is easy to adjust and comprises the light type of each dimension from top to bottom and from left to right.
Through the superposition use of the first thick-wall part 7 and the second thick-wall part 8 with the 45-degree step-shaped total reflection tangent plane, a multiplexing system shared by two functions is realized, so that a light source is in a focus position, and the lighting effect is more uniform. The arrangement of the light inlet system is arranged along with the trend of the second light-emitting patterned surface 9, the first total reflection step surface 11 and the second total reflection step surface 12 can be arranged along with the trend of the second light-emitting patterned surface 9 on the total reflection surfaces, and simultaneously, the total reflection light rays are transmitted along the rule testing direction and cannot be transmitted to the outer side of the light-emitting surface due to the factors such as the inclination angle and the shape of the total reflection surfaces, and the arrangement mode can save the inner space.
The working principle is as follows:part of light rays emitted by the first light source 1 are refracted from an air medium into the second thick-wall part 8 through the incident refraction surface 4 respectively, and then are totally emitted and collimated by the total reflection collimation surface 5 to obtain parallel light rays; the other part of the light emitted by the first light source 1 is refracted from the air medium into the second thick-wall part 8 through the incident refraction collimation surface 3 and collimated to obtain parallel light, which is beneficial to better controlling the light direction subsequently. The parallel light rays entering the second thick-wall part 8 irradiate the second total reflection step surface 12, and are totally reflected on the second total reflection step surface 12 by utilizing the total emission principle, and the light rays are further reflected by the second light-emitting pattern surface 9 to generate light ray angle change, and then are emitted to the air medium after irradiating the second light-emitting pattern surface 9.
Part of light rays emitted by the second light source 2 are refracted from an air medium into the first thick-wall part 7 through the incident refraction surface 4, and then are totally emitted and collimated by the total reflection collimation surface 5 to obtain parallel light rays; another part of the light emitted by the second light source 2 is refracted from the air medium into the first thick-walled member 7 through the incident refraction collimating surface 3 and collimated to obtain parallel light. The parallel light rays entering the first thick-wall part 7 irradiate the first total reflection step surface 11, and are totally reflected on the first total reflection step surface 11 by utilizing a total emission principle, the light ray angle is further adjusted by the first light-emitting pattern surface 6 and then is slightly upwards transmitted, the first light-emitting pattern surface 6 has a certain diffusion angle, the area of the first light-emitting pattern surface 6 is larger than that of the second total reflection step surface 12, so that the light rays are transmitted to the second total reflection step surface 12 after being emitted to an air medium, the light rays are refracted by the second total reflection step surface 12 and then become parallel light rays to enter the second thick-wall part 8 for transmission, the light rays are further reflected by the second light-emitting pattern surface 9 to generate light ray angle change, and the parallel light rays irradiate the second light-emitting pattern surface 9 and then are emitted to the air medium.
More specifically, as shown in fig. 15, the first total reflection step surfaces 11 and the second total reflection step surfaces 12 are parallel to each other in a one-to-one correspondence manner, which is beneficial to matching of light patterns, so that the emergent light from the first thick-wall member 7 can not be uncontrollably changed in the dimension in the horizontal direction, and thus the emergent light from the first thick-wall member 7 can easily meet the requirements of optical regulations. On the other hand, as the whole system only has one light-emitting surface, namely, no matter the first thick-wall part 7 or the second thick-wall part 8 is the light-emitting surface of the modeling, and no matter how the modeling is inclined or complicated, the step surfaces of the first total reflection step surface 11 and the second total reflection step surface 12 are correspondingly parallel one to one, the multiplexing functional light rays are optimally emitted from the light-emitting surface of the modeling when the whole system is multiplexed.
The vertical step-shaped total-reflection stepped surface can adjust the light angle, namely adjust the light propagation angle, so that the light angle which is originally emitted to the outer side of the light emitting surface is adjusted to the optical path direction required by design, the design is ensured, the response to various types of models and even large-angle inclined models can be flexibly realized through the shape following design of a thick-wall part system, and the space problem and the waste of the part size which cannot be avoided by the thick-wall part system originally designed for ensuring the emergent light from the modeling surface are also saved. The first total reflection step surface 11 can adjust the light emitted from the light source 2 of the first thick-wall part 7 to ensure the conformal design, the second total reflection step surface 12 can adjust the light emitted from the light source 1 of the second thick-wall part 8 to ensure the conformal design, and on the basis, the light emitted from the first thick-wall part 7 to the second total reflection step surface 12 can be further adjusted.
In the prior art, the light emitting energy distribution of the first light source 1, the second light source 2 and the light inlet system is high in the middle and low on two sides, so that the light energy entering the thick-wall part through each light inlet structure is also high in the middle and low on two sides, and the light energy is lowest at the interface position of the two light inlet systems. In the light entry system, such an energy distribution may result in a lighting effect that is bright in the middle and dark on both sides, especially near the interface. In this embodiment, as shown in fig. 13 and 14, the first light-emitting pattern surface 6 with a certain radian is used to perform a diffusion function, so that light can be diffused in the left-right direction while being emitted along the vertical stripes of the first light-emitting pattern surface 6, the light energy distribution is more uniform, and the light in the middle high-energy area is dispersed to the low-energy areas on the two sides, thereby improving the uniformity. In addition, the vertical stripes adopted by the first light-emitting pattern surface 6 are more controllable in light type and improved in uniformity compared with the whole paraboloid commonly used in the prior art because the paraboloid is replaced by the plurality of vertical stripes.
In this embodiment, the second thick-walled member 8 is arranged in front of the first thick-walled member 7, and the first light source 1 corresponding to the second thick-walled member 8 is a light source for implementing a turn function, and implements a turn light function; the second light source 2 corresponding to the first thick-walled member 7 is a position function light source, and realizes a position lamp function. The position lamp per se has low regulation and light effect requirements, emergent light from the first thick-wall part 7 at the back is incident on the second thick-wall part 8 at the front, and light refraction can be caused inevitably, so that the light effect is reduced, therefore, the first thick-wall part 7 has low regulation and light effect requirements and the second thick-wall part 8 has high regulation and light effect requirements. In addition, the second light source 2 has a higher requirement for uniformity than the first light source 1, so that the light rays with the functions realized by the first thick wall 7 enter the second thick wall member 8, and the light rays have higher uniformity.
As shown in fig. 15, if the total reflection surface is a conformal large plane, after the parallel light refracted by the light entering structure is totally reflected on the large plane, the total reflection surface is oblique, and the reflected light is also oblique, so that the light cannot be transmitted in parallel to the direction of the test center. Wherein the dotted line indicates the test center direction. As shown in fig. 16, if the total reflection surface is a large plane perpendicular to the test center direction, the parallel light refracted by the light entering system can be propagated in parallel to the test center direction after being totally reflected by the large plane. However, the light paths from the total reflection surface to the exit surface of the light rays at different positions are different, the different light paths can cause the difference of the lighting effect, the uniformity has defects, and the space occupied by the thick-walled part is larger. As shown in fig. 17, if the total reflection surface is a step surface cut from a large plane perpendicular to the test center direction, the parallel light refracted by the light entrance system can be propagated in parallel to the test center direction after being totally reflected on the step surface. And the light paths of the light rays at different positions from the total reflection surface to the emergent surface are basically consistent, the lighting effect is basically consistent, the uniformity is improved, the space occupied by the thick-wall part is smaller, the internal space in the automobile can be saved, the design space requirement is reduced, the part size is reduced, the part material is reduced, and the cost is reduced.
