The present disclosure relates to a lighting device and a vehicular lamp including the same. A lens member is provided between a shielding module and a light guide member. Through a non-air-gap structure in which a separation portion between components is removed, diversity of mechanism designs may be secured, and at the same time, light efficiency may be improved. A light emitting direction of a light emitting element forms an inclination angle with a light emitting surface of a light source module, so that a deterioration phenomenon of a light guide member formed of resin may be removed, and a light beam emitted through a first light guide member is emitted as an indirect light beam.

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 sate 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.

An illumination device, which projects a projection pattern including information onto a projection plane, includes a light source that emits a coherent light beam, and a diffractive optical element that diffracts the coherent light beam from the light source and projects the projection pattern. The diffractive optical element has a diffraction characteristic that allow an observer who sees the projection pattern from a viewpoint position in a first line-of-sight direction based on a position and a direction of the diffractive optical element, to visually recognize the information with a predetermined size, a predetermined shape and a predetermined inclination angle.

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.
