摘要： A black image type hidden light system applied to a vehicle is composed of a control module coupled to a hidden lamp module in which an outer lens, an inner lens, and a light source are assembled in a lamp housing, and a black color surface of the outer lens covers an inner space of the lamp housing to block the exposure to the outside and transmits the light fully reflected to the inner lens to the outside, thereby forming a deposition image in black when not lit and a lamp image or a lighting image when lit, and in particular, optimizes a light transmittance with an amount of addition of a carbon black material mixed with a polycarbonate (PC) material, thereby substantially enabling the mass-production beyond the limitation of an AL deposition image.

摘要： A lighting device comprises a light-emitting module with light-emitting elements, wherein the light-emitting elements are arranged adjacent to each other and are configured to emit light towards a light-emitting side. The light-emitting module is configured such that the light-emitting elements can be addressed partially independently of each other, such that some may be brought into a switched-on state while others are brought into a switched-off state. A top layer is disposed on the light-emitting module at the light-emitting side. Further comprising a switching material capable of a reversible change in transmittance for the light emitted by changing to a higher transmittance in regions where the top layer situated on light-emitting elements in the switched-on state or to a lower transmittance in regions of the top layer situated in the switched-off state. The invention further refers to methods for producing and operating a lighting device and using a lighting device.

摘要： Provided is a vehicle lighting fixture capable of suppressing the luminous intensity at a portion (e.g., a portion around 4 degrees below the horizontal line) of a low-beam light distribution pattern from becoming relatively high, and also capable of forming a low-beam light distribution pattern with a uniform vertical thickness with respect to the horizontal direction. The vehicle lighting fixture includes a projection lens, a separator disposed behind the projection lens, and a low-beam light source that is disposed behind the separator and emits light for forming a low-beam light distribution pattern by being irradiated forward through the separator and the projection lens in this order. This vehicle lighting fixture is characterized in that: the separator includes an upper separator body that has a front surface and a rear surface on the opposite side thereof, and a first light guide portion that extends from a lower portion of the upper separator body toward the low-beam light source and has a first light incident surface located at a tip end thereof and faces the low-beam light source; that the projection lens has a front surface and a rear surface on the opposite side thereof, and the rear surface of the projection lens has an upper light incident surface facing the front surface of the upper separate body; that the low-beam light source, the first light guide portion, the upper separator body, and the upper light incident surface are each disposed above a reference axis passing through the focal point of the projection lens and extending in a vehicle longitudinal direction; that the lower portion of the front surface of the upper separator body is in surface contact with the lower portion of the upper light incident surface of the rear surface of the projection lens; and that a space is formed between a portion above the lower portion of the front surface of the upper separator body and a portion above the lower portion of the upper light incident surface of the rear surface of the projection lens.

摘要： A bifocal lens module of vehicle headlight for vehicle includes a low beam condenser, a high beam condenser, a partition, a light guide member, and an optical lens. The partition has a curvy end face and an opening. The opening of the partition faces toward the optical lens. Light emitted by at least one low beam light source is converged through the low beam condenser, then transmitted from the upper position of the partition to the bottom of the partition, and eventually sent to the lower part of the optical lens. Light emitted by at least one high beam light source is converged by the high beam to condenser, transmitted from the bottom of the partition through the light guide channel to the top of the partition, and then sent to the upper part of the optical lens.

摘要： The invention relates to a light module for a motor vehicle headlamp, comprising at least one optoelectronic component (300), which is arranged in the main emission direction of a first illuminant (110) and which comprises a controllable arrangement of a plurality of micromirrors (310), which can be pivoted into a first and a second position. Micromirrors (310) that are in the first position deflect light beams toward at least one projection optical unit (400), which is designed to produce a light distribution. Micromirrors (310) that are in the second position deflect light beams toward a light-beam-absorbing absorber (500). The light module also comprises at least a control device (200), a sensor element (600) and a second illuminant (120). The control device (200) is designed to control the sensor element (600) and the second illuminant (120). Micromirrors (310) that are in the first position deflect the light beams that can be emitted by the second illuminant (120) toward the sensor element (600). The sensor element (600) is designed to sense light beams from the second illuminant (120) in order to obtain a value, and to transmit said value to the control device (200), which compares the value with a threshold value stored in a memory. Switching on of the first illuminant (110) is prevented when the threshold value is reached, or the first illuminant (110) is switched on when the threshold value is fallen below.
