A luminous curtain device has a luminous curtain, a side member, and a luminous module. The side member is mounted on a side of the luminous curtain. The luminous module is mounted in the side member, and projects light on ends of optical fibers of the luminous curtain. The luminous curtain device is applied on sunlight-shading products for an automobile to shade sunlight. The luminous module can project light on the luminous curtain to make the luminous curtain luminous with a decorative effect.

A vehicle is provided that includes a glazing that has a first glass substrate and a second glass substrate. A polymeric interlayer is positioned between the first and second glass substrates and a phosphorescent layer is positioned on the polymeric interlayer. A light source is optically coupled with polymeric interlayer.

The disclosure relates to an interior trim part of a motor vehicle, which includes a support layer (10), a cover layer (14) on a front side of the support layer and an illumination unit (16-26) on an opposite rear side of the support layer. The support layer includes a perforation (12), which forms an illuminated structure when the illumination unit emits light through the perforation.

An object is to provide a light-emitting element which uses a plurality of kinds of light-emitting dopants and has high emission efficiency. In one embodiment of the present invention, a light-emitting device, a light-emitting module, a light-emitting display device, an electronic device, and a lighting device each having reduced power consumption by using the above light-emitting element are provided. Attention is paid to Förster mechanism, which is one of mechanisms of intermolecular energy transfer. Efficient energy transfer by Förster mechanism is achieved by making an emission wavelength of a molecule which donates energy overlap with a local maximum peak on the longest wavelength side of a graph obtained by multiplying an absorption spectrum of a molecule which receives energy by a wavelength raised to the fourth power.

A light-producing assembly is provided herein and includes a first portion of LEDs biased to direct light in a first direction, a second portion of LEDs biased to direct light in a second direction that is different than the first direction, and a controller for selectively activating the first and/or second portions of LEDs.
