A surface lighting module may include: a light source configured to emit light; a main reflection part configured to reflect light emitted from the light source; a light guiding part that is provided at an upper portion of the main reflection part and spreads light reflected from the main reflection part to have a surface shape; and a lateral reflection part that is attached to a lateral surface of the light guiding part and reflects light leaking to the lateral surface of the light guiding part.

A computing system for a vehicle is provided. The computing system includes one or more processors for controlling operation of the computing system, and a memory for storing data and program instructions usable by the one or more processors. The one or more processors are configured to execute instructions stored in the memory to determine if the vehicle is operating with at least one occupant inside the vehicle. If the vehicle is operating without at least one occupant inside the vehicle, the system may control the vehicle so as to disable and/or deactivate selected ones of driver-usage systems/components and passenger-usage systems/components.

The present disclosure provides a head-up display that has a first lighting unit to display first information on a windshield. The first lighting unit includes a first lighting source that emits light for the windshield as the first information and a first cylindrical casing that accommodates the first lighting source therein. The head-up display further has a second lighting unit to display second information on the windshield. The second lighting unit includes a second lighting source that emits light for the windshield as the second information. The head-up display further has a package disposed under the windshield. The first and second lighting units are installed on the package. The second lighting unit is installed on the package independently from the first lighting unit.

A vehicle lighting device and a method of controlling luminance thereof are provided. The vehicle lighting device includes a camera module configured to capture an image of the driver's face, a sensing unit configured to detect the surroundings of a vehicle, a lighting unit including at least one light source to illuminate the interior of the vehicle, and a controller. The controller is configured to acquire information on a daytime mode and a nighttime mode through the sensing unit, to acquire information on an infrared brightness level or information on the size of the pupil of the driver's eye based on the image of the driver's face captured by the camera module, and to control the luminance of the lighting unit in response to the acquired information.

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.
