A lighting module includes a semiconductor laser element configured for emitting a laser beam in an emission cone, a light-emitting element, and a reflecting surface, a main portion of which reflects light coming from the light-emitting element in order to form an outgoing light beam. A secondary guiding face reflects the light coming from the first emission cone into a measurement cone. Also included is a device for detecting incident light exceeding a predetermined threshold of light intensity which is arranged within the measurement cone. The optical structure of the guiding face causes a spreading of the light so that the measurement cone exhibits an aperture angle greater than that of the first emission cone.

The invention relates to a light module including a semiconductor laser element emitting a laser beam in a first cone of light, a photoluminescent element, and an optical means for transforming the light coming from the photoluminescent element into an exit light beam. The optical means has a guiding portion arranged to guide at least a portion of the light emitted in the first cone of light into a second cone of light and a device for detection of incident light. The light module comprises a means of deviation designed to deviate the light of the second cone of light toward a third cone of light directed toward the detection device arranged outside of the second cone of light.

A method for detecting damage to a converter device of a lighting apparatus is provided. The method may include irradiating the converter device with input light, detecting a useful light portion emitted principally by a first section of the converter device by means of a first sensor element. A first detection signal is obtained, detecting a useful light portion emitted principally by a second section of the converter device, said second section being different than the first section, by means of a second sensor element. A second detection signal is obtained. The method further may include automatically obtaining damage information about the converter device from a ratio or a difference of the first detection signal with respect to either the second detection signal or a comparison signal formed therefrom.

When light is off, a transparent appearance is obtained, while when the light is on, light is seen through a transparent spot. The present invention includes a light source portion and a reflective portion. The light source portion emits light. The light source portion is disposed at a position shifted with respect to an emitting direction of emitted light from the reflective portion. The reflective portion reflects the light from the light source portion and emits it in a predetermined direction. The reflective portion is constituted by a transparent member with a refractive index at least in a visible light area larger than 1. As a result, in the present invention, the transparent appearance is obtained when the light is off, while the light is seen through the transparent spot when the light is on.
