The present invention relates to a luminous vehicle sunroof that includes a first glazing with first and second main faces, a light-emitting element such as an OLED or QLED and a collimating optical system with one or more optical films.

A digitally controlled LED illuminator sheet that produces far-field illumination patterns or light field distributions that increase light utilization and application efficiency. A dynamic directional LEDs (or other kinds of solid-state light sources) sheet is positioned under each lenslet of a microlens array. Individual LED beam pointing direction depends on off-axis position relative to optical axis of lenslet. Individual beams from independent LEDs form illumination pixels at the illumination plane or within a volume space and can be modulated in intensity. Illumination pixels partially overlap in far-field illumination plane and illumination volume. Data from sensors can be collected and the LEDs can be digitally turned on or off and/or pulse width or amplitude modulated based on sensor data to produce far-field illumination patterns or light field distributions with spectral efficiency and efficacious intensity.

The present disclosure is an improvement in bi-focus lenses. The disclosure relates to the use of multiple channels of LED/Lens combinations to achieve a smooth and continuous range of emitted beam angles of light in a wider range of beam angles than previously possible through only two channels of LED/Lens combinations. The resultant product will produce a continuous range of beam angles in a range exceeding 35 degrees from narrowest bean angle to widest beam angle. The lens channels selected are weighted so as to maximize the contribution of a single channel lens to the overall beam projection.

A light emitting module includes: a first light source comprising a first light emitting element configured to emit first light, and a first wavelength conversion member configured to convert a wavelength of a portion of the first light and to emit second light, such that the first light source is configured to output light that includes the first light and the second light; a first lens on which the light output from the first light source is incident; a drive unit configured to change a distance between the first lens and the first light source so as to change an amount of outgoing second light from the first lens; a second light source configured to output light having a chromaticity that is different from that of the light output from the first light source; and a second lens on which the light output from the second light source is incident.

A lamp includes at least two illumination parts and a lamp body. The lamp body has an upper portion, a lower portion corresponding to the upper portion and at least two optical cavities extended between the upper portion and the lower portion. The illumination parts are respectively arranged in the optical cavities. The lamp has a surrounding lighting state and a side lighting state. The lighting states of the lamp may be switched between the surrounding lighting state and the side lighting state through controlling the operating modes of the illumination parts in the optical cavities respectively.

A lighting device may include an elongated housing that defines a cavity. The lighting device may include plurality of emitter printed circuit boards configured to be received within the cavity. Each of the plurality of emitter printed circuit boards may include a plurality of emitter modules mounted thereto. Each of the plurality of emitter printed circuit boards may include a control circuit configured to control the plurality of emitter modules mounted to the respective emitter printed circuit board based on receipt of one or more messages. The lighting device may include a total internal reflection lens for each of the plurality of emitter printed circuit boards. The total internal reflection lens may be configured to diffuse light emitted by the emitter modules of the plurality of emitter printed circuit boards.

A luminaire and LED light engine are provided. The luminaire includes the LED light engine and an optical device. The LED light engine includes an LED array and a partial diffuser. The partial diffuser diffuses light that is emitted by LEDs of a selected first subset of LEDs in the LED array and leaves undiffused light that is emitted by LEDs of a second subset of LEDs in the LED array. At least some LEDs are selected for inclusion in the first subset as emitting light that produces poorly blended colors in a light beam emitted by the LED array. The optical device is configured to receive a light beam emitted from the LED light engine and emit a modified light beam.

A lighting assembly that includes a heatsink housing, a plurality of light emitting diode (LED) modules, and a power supply disposed within a power supply casing, wherein the power supply is for providing power to the LED modules. Each LED module includes a plurality of LEDs and is thermally connected to the heatsink housing. The power supply casing includes a structure for cooling the power supply.
