摘要： A light device comprises a laser light source, a primary optical system with at least one diffractive and/or at least one reflective optical element to convert monochromatic coherent light to a collimated beam of coherent light, a MOEMS comprising one or more micro-mirrors to route coherent light and convert it to white light, and a secondary optical system comprising at least one diffractive and/or at least one reflective optical element to direct white light from the light device to create a light pattern on the display surface and/or in specific zones in front of the vehicle. It further comprises an electromagnetic control system connected to the MOEMS and the light source to control changes of rotation angle, oscillation angle and oscillation rate and frequency of one of the micro-mirrors, and to control the light source activity, for controlled changing of the shape and/or position of the light pattern depending on current conditions of the vehicle.

摘要： A vehicle headlight has a segmented light guide device in which segments are selectively controlled to operate in an output state that reduces glare to oncoming vehicle drivers. Vehicle sensors and controller circuitry are used to identify areas of glare removal in the light pattern of the headlight and control the corresponding segments in the light guide device to operate in a selected light output state that reduces glare. The segments can be operated in a focused output state for vehicle driver visibility, or in a scattered output state to reduce glare. The segments can be operated in a clear or transparent output state for vehicle driver visibility, or in a reflected output state to reduce glare. Reflected light can optionally be re-directed. The light guide device can employ bi-stable liquid crystal shuttering or liquid crystal switchable mirror technology.

摘要： Disclosed is a condenser and a high-and-low-beam integrated vehicle lamp module, the condenser comprises at least one light incident portion, a light-transmitting portion, and a light emergent portion, wherein a 50L dark area light shape forming structure is formed on the light-transmitting portion; the 50L dark area light shape forming structure protrudes from a surface of the light-transmitting portion and has a slope surface; and the distance from the slope surface to the surface of the light-transmitting portion gradually increases from a position close to the light incident portion to the light emergent portion. Since the 50L dark area light shape forming structure protrudes out of the surface of the light-transmitting portion and has the slope surface, in a high-beam illumination mode, some light is emitted from the 50L dark area light shape forming structure to a 50L test point.
