Problems solved by technology

However, other beams cannot be processed correctly and thus spread the very dangerous coherent laser beam 20B
[0014] Other types of deterioration (less visible and thus harder to detect) may occur
For example, a vehicle that includes this type of light module and is frequently subjected to exceptional weather conditions (extremely hot or cold for extended periods of time) or subjected to small but very frequent impacts may exhibit a slow deterioration of the treatment module 8
It is especially difficult to detect this type of slow deterioration

Embodiment Construction

[0070] In the following, the lamp module according to the invention is described with its non-limiting application to a lighting device for a motor vehicle. Other applications are also conceivable, for example the device according to the invention as a headlight or interior decoration of a motor vehicle, as a Christmas tree light or even as a signaling panel.

[0071] The modules are configured, for example, to perform one or more photometric functions.

[0072] A photometric function is, for example, an illumination and / or signaling function visible to the human eye. Note that these photometric functions may be the subject of one or more regulations establishing the requirements for chromaticity, intensity, spatial distribution according to a so-called photometric grid or even line-of-sight of emitted light.

[0073] A lighting device comprising a module according to the invention is, for example, a lighting device and then forms a headlight of a vehicle, which is then confi...

Abstract

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 (26) 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.

Description

technical field [0001] The invention relates to the field of lamp modules comprising a laser source. In particular, it relates to a device and a method for securing the lamp module. [0002] The invention is particularly advantageous when it is implemented in a lighting device contained in a vehicle and comprising a light module. Background technique [0003] "Light emitting device" should be understood as any device capable of emitting light. For example, a vehicle's headlamp or lamp, a small lamp, a lamp contained in the interior of a vehicle, a night light contained in a seat of a train car, a part of a television screen, or even a high-intensity searchlight on a coast guard vessel is a source of light. An example of a device. A vehicle should be understood as any type of device capable of moving, eg a car, truck, moped, plane, train or even a sled. [0004] A "lamp module" should be understood as any type of sub-assembly of a lighting device from which light is emitt...
