摘要： The invention relates to a light module including a laser source capable of emitting a coherent light beam of given wavelength, a first sensor capable of picking up a first light signal of a wavelength lying in a first band of wavelengths centered around the given wavelength and a second sensor capable of picking up a second light signal of a wavelength lying in a second band of wavelengths centered around a wavelength distinct from the given wavelength. In particular, the light module includes a detection module capable of comparing at least one value that is a function of the signals to a threshold value and of commanding the stopping of the laser source as a function of the comparison.

摘要： A headlight system can include a laser driving circuit to drive a laser device, a detecting circuit to detect a current of the laser device, a wavelength converting material to emit light having a white color tone associated with the laser device, a receiver circuit to detect a light-intensity of the light via a photo detector and a controller. The controller can control the laser driving circuit while watching normal/abnormal states of an optical structure of the system. Thus, the disclosed subject matter can provide the headlight system, which can provide favorable light distribution patterns by using the light, even when a battery voltage returns the laser device to the normal state after the controller outputs a turn-off signal to the laser driving circuit not to emit the laser device by detecting the abnormal state in the optical structure such as the laser device because the battery voltage largely decreases.

摘要： In order to ensure accuracy for positioning two molding members spaced from each other and an outer lens disposed in an opening between the two molding members, a vehicle lighting device includes: a first molding member; a second molding member that is formed separately from the first molding member and is spaced from the first molding member through an opening; and an outer lens, disposed in the opening, having a transmissive surface through which lamp light is transmitted from a depth side toward a front side. The first molding member and the second molding member each have a molding-side positioning portion configured to be positioned relative to the transmissive surface of the outer lens. The outer lens has a first lens-side positioning portion configured to be positioned relative to the first molding member and a second lens-side positioning portion configured to be positioned relative to the second molding member.

摘要： The present invention pertains to a multi-functional luminous device for an automotive vehicle. The luminous device comprises two light sources adapted to generate different photometric functions. A light source support having two functional areas accommodates a first light source for generating first photometric function and a second functional area accommodates a second light source (10b) for generating second photometric function. Additionally, a groove is provided between adjoining functional areas and a shield is partially inserted into the groove for blocking the light between adjoining functional areas.
