An organic EL lighting device for a vehicle is provided, which includes an organic EL lighting portion provided in a matrix form on a ceiling of the vehicle, an organic EL touch portion provided on the organic EL lighting portion, an organic EL detection portion for detecting a position in which the organic EL touch portion is touched, an organic EL determination portion for determining a lighting area of the organic EL lighting portion based on the position detected by the organic EL detection portion, and an organic EL driving portion for lighting the lighting area of the organic EL lighting portion determined by the organic EL determination portion.

A method of controlling an ambient light feature of a cup holder assembly having one or more cup holders includes providing a light source having a light output of varying luminous intensity, sensing an amount of light reflected from an object received in one of the cup holders using a light sensor, and controlling the luminous intensity of the light output based on the amount of light reflected and the distance between the object and a sidewall of the cup holder assembly. In this method, a change in the amount of light reflected from an object received in one of the cup holders correlates to a change in the luminous intensity provided by the light source, and a change in the distance between the object received the cup holder and the sidewall of the cup holders correlates to a change in the luminous intensity provided by the light source.

The invention discloses an automobile skylight optical structure with light effects of both lighting and color atmospheres and belongs to the technical field of automobile skylight optics. The automobile skylight optical structure with the light effects of both lighting and color atmospheres comprises skylight glass, wherein a fixed light shielding bracket frame is fixedly connected with the lowerend of the skylight glass; the lower end of the skylight glass is coated by a light shielding black ink corresponding to the fixed light shielding bracket frame; the fixed light shielding bracket frame is completely shielded by the light shielding black ink; protection glass is fixedly connected with the lower end of the fixed light shielding bracket frame; a light diffusion medium ring is arranged between the skylight glass and the protection glass; light guide glass is fixedly connected with the lower end of the light diffusion medium ring. A uniform surface light emission source is provided by a skylight, and a projection surface light source is adopted to form uniform in-vehicle light, so that the uniformity of in-vehicle space illuminance is improved, an optical scene effect of an in-vehicle space multimedia dynamic colorful atmosphere is improved, and the phenomenon of bright zones and dark zones caused by a conventional lateral entrance optical structure is solved.

The invention provides a carpet unit comprising a laminate of a tufted primary backing layer providing a carpet unit top face, an intermediate adhesive layer, and a backing layer providing a carpet unit back face, wherein the carpet unit is selected from the group consisting a carpet and a carpet tile, wherein the carpet unit further comprises an optical sensor, arranged to generate a sensor signal, wherein, seen from carpet unit top face, the optical sensor is arranged behind the primary backing layer, and wherein the carpet unit is arranged to transmit light from the carpet unit top face to the optical sensor.

The invention relates to a vehicle, which comprises a main driver seat, a passenger seat and a central panel, wherein a first area and a second area are the interior space above the main driver seat and the passenger seat in the vehicle respectively; the central panel is provided with a display device, which comprises a display screen and a backlight, wherein the backlight comprises a lens part and a light-emitting part; the lens part comprises a positive lens unit, the light-emitting part comprises a corresponding light-emitting unit group, the light-emitting unit group comprises a first light-emitting body and a second light-emitting body in horizontal side-by-side arrangement, the first light-emitting body and the second light-emitting body are positioned between a first focal plane anda second focal plane of the lens unit and are opposite to the main driver seat and the passenger seat; the display screen is arranged on the lens part, the first light-emitting body and the second light-emitting body alternately emits light, the display screen alternately brushes out a first image and a second image corresponding to the display time, so that the first image and the second image are projected to the first area and the second area respectively. By means of the vehicle, the same-screen display device can not only meet the requirements of the passengers seating at the main driverseat and passenger seat for viewing individual display images, but also can ensure that the display images with high enough brightness can be watched.

The RGB atmosphere lamp holder comprises a shell, a circuit board module and a light mixing lens, wherein the circuit board module and the light mixing lens are arranged in the shell. The shell is internally provided with a cavity for placing the circuit board module and a light emitting cavity for communicating the cavity with the outside; the light outlet cavity comprises a lens cavity part for placing a light mixing lens; the circuit board module comprises a PCB (Printed Circuit Board) and RGB-LED lamp beads fixed on the PCB; the light inlet end of the light mixing lens is close to the RGB-LED lamp bead. The RGB atmosphere lamp holder has the advantages that the RGB atmosphere lamp holder has the light mixing function, three-color light emitted by the RGB-LED lamp beads firstly enters the light mixing lens to be mixed, then mixed light is emitted outwards after mixing, in other words, the RGB atmosphere lamp holder can directly emit the mixed light formed by mixing the three colors, and the RGB atmosphere lamp holder can be suitable for atmosphere lamps needing to directly input the mixed light.
