20210086691 · 2021-03-25 ·

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.

VEHICLE LAMP

A vehicle lamp, which can make objects in a lamp chamber invisible, includes: a lamp housing and a lamp lens forming a lamp chamber, an excitation-light irradiation unit, a light conversion unit, and an optical filter disposed in the lamp chamber. The optical filter is disposed between the excitation-light irradiation unit and the light conversion unit and blocks light in a specific wavelength range. As a result, such a phenomenon that an image from an outside is seen in the lamp chamber through the lamp lens or an object in the lamp chamber is seen through the lamp lens can be suppressed, and the object in the lamp chamber can be made invisible.
