Abstract: The present invention relates to a vehicle composite reflection and refraction multi-imaging device including a reflecting surface, a semi-reflecting surface, and a concave lens. At least one image of at least one light source is reflected repeatedly by the semi-reflecting surface and the reflecting surface to form a plurality of visible mirror images on a mirror image side of the reflecting surface. The concave lens is disposed at the viewing side. A viewer at the viewing side views a plurality of visible mirror images at the mirror image side of the reflecting surface through the refracting of the concave lens. The reflected and refracted visible mirror images gradually shrink towards a vertical axis. Visible mirror images do not interfere with one another, and each visible mirror image is clear. The visible mirror images can generate an apparent inward-shrinking 3D effect of depth with levels.

Abstract: The invention provides a light guide device for vehicle, including at least one incident portion, a diffusion surface and a reflective portion. The at least one incident portion is disposed on at least one end of the light guide device, and is used to receive at least one light source. The diffusion surface is used to export light, and the diffusion surface has a plurality of zigzag structures. The reflective portion is opposite to the diffusion surface, and is used to reflect light to the diffusion surface. The incident portion is disposed between the diffusion surface and the reflective portion. Therefore, by using the light guide device, light can be fully reflected in the light guide device, and light is exported by the diffusion surface. Thus, no light will leak to the outside through the reflective portion, thereby greatly increasing light guiding efficiency of the light guide device.

Abstract: A vehicle headlight capable of compensating for light intensity of a dark region includes a lamp holder, a light source, a light shield, and a light guide. The lamp holder defines an accommodation space, and includes a reflector and a lens disposed on a front side of the reflector. The light source is installed in the accommodation space and disposed along an optical axis, and light rays emitted from the light source are refracted by the lens and emitted forwards. The light shield is assembled on the lamp holder and located between the light source and the lens, and the light shield is used to shield some of the light rays emitted from the light source. The light guide conducts some of the light rays towards the lens, such that the light rays are emitted forwards and upwards, thereby compensating for the light intensity of the dark region above the optical axis.

Abstract: A method for detecting errors in driving device of head light of vehicles utilizes a microprocessor control unit of a main circuit to detect the position of the driving shaft by checking the change of magnetic field or resistance of the driving member and the change of magnetic field or resistance is compared with a pre-set value to decide the position of the driving shaft. The motor is then commanded to drive the driving shaft to the pre-set position. The method detects the position of the head light before the drivers drive the vehicles on the road and if the head light is not in a desired position, the user can adjust the head light position to prevent potential risk on the road.
