A device for signal light display and environment detection includes a first light source for emitting visible light in a first spectral range in a temporally modulated manner, and a light source for emitting invisible light in a second spectral range. A lighting surface is designed to reflect and/or transmit light in the first spectral range in a diffused manner. A material layer is transparent for light in the second spectral range, or reflects this light with almost no diffusion. A deflection unit in the device deflects the light from the first light source onto the lighting surface and the light from the second light source onto the material layer. The material layer is located in relation to the deflection unit such that invisible light deflected onto the material layer is emitted for environment detection in an environment of the device.

An illumination apparatus that illuminates an illumination zone having a first direction and a second direction crossing the first direction is provided with a light source to emit a coherent light beam, and a diffraction optical device to diffract the coherent light beam incident from the light source. The diffraction optical device diffracts the incident coherent light beam so that a width of the illumination zone in the second direction gradually becomes wider along the first direction of the illumination zone from a nearer side to the diffraction optical device.

A multi-purpose light bulb is shown and described. The multi-purpose light bulb includes at least one lighting element. The at least one lighting element is electrically coupled to an electrical connection. The electrically connection is electrically coupled to at least one speaker. The speaker and the lighting element are coupled such that the electrical connection will supply power to both at the same time. The multi-purpose light bulb further includes a wireless transceiver. The wireless transceiver is wirelessly connected to a device running an application that controls various aspects of the multi-purpose light bulb.

A vehicle headlight (1), which is one aspect of a vehicle illumination lamp, includes: light sources (52R, 52G, 52B), and diffraction gratings (54R, 54G, 54B) for diffracting light incident from the light sources (52R, 52G, 52B). The light diffracted by the diffraction gratings (54R, 54G, 54B) is irradiated in a predetermined light distribution pattern. A projection area (AR) to which are projected components (LC.sub.R, LC.sub.G, LC.sub.B) advancing and passing through the diffraction gratings (54R, 54G, 54B) among the light incident on the diffraction gratings (54R, 54G, 54B) is positioned below the light distribution pattern and within a range (RNG) in which a field of view of a driver of a vehicle is obstructed by the vehicle.

A lighting device is attached to a vehicle and includes a forward facing visible light source that emits visible light in a forward direction relative to the vehicle. The lighting device further includes a rearward facing ultraviolet light source that emits ultraviolet light in a rearward direction relative to the vehicle, such that a reflecting material of an object, which is not illuminated by the visible light source, is illuminated by the ultraviolet light source. A control device is connected to the light sources, and is configured to turn the light sources on and off. A light sensor is connected to the control device and is configured to sense ambient light and to provide a signal to the control device. The control device is configured to turn the ultraviolet light source on and off responsive to the signal of the light sensor.
