A lighting device and a method of manufacturing a lighting device are described. The lighting device includes a heat sink having a mounting area. A main board is mounted to the mounting area of the heat sink, the main board including a recess. A light-emitting diode (LED) assembly is mounted to the mounting area within the recess of the main board. The LED assembly includes at least one emitter. Electrical circuitry is disposed on the top surface of the main board, which is configured to control the at least one emitter of the LED assembly. An electrical connection is provided between the LED assembly and the electrical circuitry.

This system for detecting the surrounding conditions of a moving body forcibly changes the state of at least one of a plurality of lighting devices (change from an unlit state to a lighting state or a blinking state, change in the emission color, or change in the luminance) installed inside the moving body, if an object to which attention must be paid during traveling of the moving body is detected in the surroundings of the moving body.

Methods and apparatus for driving an emitter array are described. A method includes determining a thermal environment profile for a plurality of emitters of the emitter array, computing a current pulse profile for at least one of the plurality of emitters based on the thermal environment profile, and applying a current pulse with the computed current pulse profile to the at least one of plurality of emitters.

The present disclosure provides a lampshade structure, an unmanned aerial vehicle (UAV) arm, a UAV, and a movable platform. The lampshade structure may comprise a first light-transmitting surface of a lampshade body close to a light-emitting element and a second light-transmitting surface of the lampshade body away from the light-emitting element; wherein the first light-transmitting surface may include a scattering structure to outwardly refract light emitted by the light-emitting element to expand a light-emitting angle and an irradiation direction of the light-emitting element, thereby obtaining sufficient light in a desired direction.

A vehicle assembly includes, among other things, a lighting assembly moveable back and forth between an attached position and a detached position. The lighting assembly spans from a first rail assembly of a vehicle to a second rail assembly of the vehicle when the lighting assembly is in the attached position. A vehicle lighting method includes, when a lighting assembly is in an attached position, engaging a first end portion of the lighting assembly with a first rail assembly of a vehicle, and when the lighting assembly is in the attached position, engaging an opposite, second end portion of the lighting assembly with a second rail assembly of the vehicle. The lighting assembly is configured to illuminate an area adjacent a vehicle when the lighting assembly is in the attached position.
