Example 3:
the present embodiment will be understood by those skilled in the art as more specific descriptions of embodiment 1 and embodiment 2.
The projection system provided in this embodiment includes a light source and a transparent total reflection projection structure, where the light source may select a laser light source and an LED light source, and the transparent total reflection projection structures corresponding to the different light sources are different.
The total reflection projection optical system using the laser light source comprises the laser light source, a laser beam expansion surface, a total reflection optical surface, a total reflection light ray expansion surface, a paint spraying light ray absorption surface and a laser carving modeling light-emitting surface. The laser light is emitted from the laser light source, and the emission angle is extremely small and almost highly collimated due to the characteristic of high directivity of the light beam emitted by the laser light source, so that the emission angle of the light beam needs to be unfolded by utilizing the laser beam expansion surface to facilitate subsequent light diffusion.
The laser beam expansion surface is a sphere-like optical surface that spreads the light as the laser beam is refracted from the air medium through the laser beam expansion surface into the plastic medium. After passing through the laser beam expansion surface, the light irradiates the full-emission optical surface, the full-emission principle is utilized to generate full emission on the full-reflection optical surface, and the light further increases the light emitting angle, so that the light is reflected to the paint spraying light absorption surface and the laser engraving modeling light emitting surface, and after the light irradiates the paint spraying light absorption surface, the light is absorbed by the black paint to prevent the light from refracting to an air medium.
The total reflection light expansion surface is a total reflection surface with a certain curvature, so that the light can be totally reflected to obtain the reflection light with a larger overall light emitting angle, and the light can be widely applied to a paint spraying light absorption surface and a laser carving modeling light emitting surface, thereby being beneficial to enlarging the area of the subsequent projection light. After the light rays are irradiated to the light emitting surface of the laser engraving shape, the light rays enter an air medium through refraction of the light emitting surface of the laser engraving shape, the light rays are refracted on the light emitting surface of the laser engraving shape and further spread the light emitting angle, then the light rays can be projected to a vehicle body, a large-area projection lighting effect of 180 degrees is achieved by utilizing the light emitting angle of the light rays and the distance between the light emitting surface 6 of the laser engraving shape and the vehicle body, the total reflection optical surface 3 is a tangential surface which is mainly made for saving space, the total reflection optical surface 3 can be canceled according to actual modeling requirements, all the rest optical surfaces are mirrored by taking the total reflection optical surface 3 as a reference, and the projection structure after mirroring can achieve a large-area projection lighting effect of 360 degrees.
The design of the laser engraving modeling light-emitting surface is obtained by comprehensively considering the variables of the requirements of customers on the final projection effect, the distance between a projection area and a paint-spraying light-absorbing surface and the angle of light striking the paint-spraying light-absorbing surface. The modeling of the customer is regular or irregular and can be realized through different laser carving light-emitting surface designs. And the basal plane of the laser engraving modeling light-emitting surface is slightly higher than the integral paint-spraying light-absorbing surface, so that the black paint on the light-emitting surface can be removed more accurately during laser engraving. And the laser engraving modeling light-emitting surface is an arc surface with a certain angle, so that the light can be assisted to have certain convergence in the width direction, and the radian optical surface can further concentrate light, so that the outline of the projected pattern is clearer and sharper.
The projection of the car bodies with different models is realized, and the design of the laser engraving model light-emitting surface is important. The projection area of the automobile body is defined by a customer, the distance L between the projection area and the projection structure can be preset to be known, the light-emitting angle requirement required by the emergent light of the laser engraving type emergent light face of the projection result can be obtained through the area of the whole projection area and the distance L, the light meeting the light-emitting angle requirement can be obtained through the design of the total reflection light expansion face and the laser engraving type emergent light face in the projection structure, and finally the automobile body projection effect meeting different modeling requirements is realized.
The total reflection projection optical system using the LED light source comprises the LED light source, an incident refraction surface, a total reflection plane, a total reflection collimation surface, a refraction collimation surface, a total reflection plane, a total reflection light expansion surface, a paint spraying light absorption surface and a laser carving modeling light-emitting surface. The light emitted by the LED light source is refracted from the air medium through the incident refraction surface and enters the plastic medium, and then is totally reflected and collimated by the total reflection collimation surface, so that parallel light is obtained. Light emitted by the LED light source is also refracted from the air medium through the refraction collimation surface, enters the plastic medium and is collimated, and parallel light is obtained. Light rays emitted by the LED light source enter the plastic medium and are all collimated into parallel light rays, so that the follow-up better control of the light ray direction is facilitated.
The parallel light irradiates the straight total reflection light expansion surface, total reflection occurs on the total reflection light expansion surface by utilizing the principle of total emission, the light further increases the light emitting angle, the light irradiates to the paint spraying light absorption surface and the laser engraving molding light emitting surface, the total reflection light expansion surface is a total reflection surface with a certain curvature, the parallel light can generate total reflection to obtain reflection light with a larger overall light emitting angle, and the light can strike the paint spraying light absorption surface and the laser engraving molding light emitting surface in a larger range, so that the area of the subsequent projection light is increased.
After the light irradiates the paint-spraying light absorbing surface, the light is absorbed by the black paint, and the light is prevented from being refracted to an air medium. After the light irradiates the light-emitting surface of the laser engraving shape, the light enters an air medium through refraction of the light-emitting surface of the laser engraving shape, and the light can be projected to a vehicle body after being refracted on the light-emitting surface of the laser engraving shape and further diffused by a light-emitting angle. The 180-degree large-area projection lighting effect is realized by utilizing the light emitting angle of the light rays and the distance between the laser engraving modeling light emitting surface and the vehicle body. The total reflection optical surface is mainly a tangent plane for saving space, the total reflection optical surface can be canceled according to actual modeling requirements, all the rest optical surfaces are mirrored by taking the total reflection optical surface as a reference, and the mirrored projection structure can realize 360-degree large-area projection lighting effect.
The design of the laser engraving modeling light-emitting surface is obtained by comprehensively considering 3 variables of the requirement of a customer on the final projection effect, the distance between a projection area and a paint spraying light ray absorption surface and the light ray angle of the paint spraying light ray absorption surface. The modeling of the customer is regular or irregular and can be realized through different laser carving light-emitting surface designs. And the basal plane of the laser engraving modeling light-emitting surface is slightly higher than the integral paint-spraying light-absorbing surface, so that the black paint on the light-emitting surface can be removed more accurately during laser engraving. And the laser engraving modeling light-emitting surface is an arc surface with a certain angle, so that the light can be assisted to have certain convergence in the width direction, and the radian optical surface can further concentrate light, so that the outline of the projected pattern is clearer and sharper.
The projection of the car bodies with different models is realized, and the design of the laser engraving model light-emitting surface is important. The projection area of the automobile body is defined by a customer, the distance L between the projection area and the projection structure can be preset to be known, the light-emitting angle requirement required by the emergent light of the laser engraving type emergent light face of the projection result can be obtained through the area of the whole projection area and the distance L, the light meeting the light-emitting angle requirement can be obtained through the design of the total reflection light expansion face and the laser engraving type emergent light face in the projection structure, and finally the automobile body projection effect meeting different modeling requirements is realized.
The projection optical system of the application projects a target on a vehicle body, and the projection effect is related to the distance between a projection area and the projection optical system and the design of a light emergent surface and a total reflection optical expansion surface on the projection optical system. When the distance is small, if a small projection pattern is desired, the size of the light emitting surface of the light can be reduced, or the expansion degree of the total reflection light expansion surface can be reduced; when the distance is small, if a large projection pattern is desired, the size of the light emitting surface of the light ray can be increased, or the expansion degree of the total reflection light ray expansion surface can be increased; when the distance is large, the same is true. Meanwhile, the width of the projection area can be adjusted by adjusting the width of the light emergent surface.
The projection optical system has small whole volume and small occupied space, and when the distance between the projection area and the car lamp is too small or too large, the position of the projection optical system in the car lamp can be adjusted, so that the distance adjustment range is further enlarged. The whole system can meet the requirement of diversified projection modeling of customers through the design adjustment of the light emergent surface and the total reflection optical expansion surface and the adjustment of the position of the projection optical system in the car lamp.
The application uses the LED or the laser light source, utilizes the total reflection projection structure to spread the light to 180 degrees, and projects the light to the vehicle body in a large area according to the modeling requirement.
