摘要： A radiation-emitting semiconductor chip includes a semiconductor layer sequence having an active layer for generating electromagnetic radiation. The semiconductor chip also includes a reflector at a side surface of the semiconductor layer sequence having a reflector surface facing the semiconductor layer sequence and extending obliquely with respect to the active layer. The semiconductor chip further includes a top surface extending transversely with respect to the reflector surface and having a first emission region. The semiconductor chip additionally includes a further reflector situated opposite the reflector. The semiconductor chip is configured such that electromagnetic radiation generated in the active layer during operation is reflected by the reflector and emerges from the semiconductor chip via the emission region of the top surface. A main emission direction of the emerging electromagnetic radiation together with the active layer form an emergence angle of between 30° and 80° inclusive.

摘要： A vehicle lamp may include a first light image forming unit configured to form a first light image, a second light image forming unit configured to form a second light image, and a controller configured to control the first light image forming unit and the second light image forming unit in response to an input operation command. In particular, the controller is configured to control the first light image forming unit to cause a luminous intensity of the first light image to be increased in response to a target operation command for a target operation of the second light image forming unit being input in a state in which the first light image forming unit forms the first light image.

摘要： Light-based devices may be provided that emit light. The light-based devices may be incorporated into systems such as vehicles. The light-based devices may include light sources such as light-emitting diodes and lasers. Mirrors may be used to collimate light from the light sources. Light modulators may be used to pattern light from the light sources. The light sources may include light sources of different colors. Arrays of pixels may be used to provide dynamically varying patterns of emitted light. A light source may produce light that is diffracted by an array of diffractive elements on a window. Mechanical and electrical shutters may obscure light sources, mirrors, and light-emitting components mounted on windows.

摘要： An opening and closing system includes a first human detection sensor configured to detect a vehicle user who enters a first area defined on a periphery of a vehicle body, a lamp visible by the vehicle user who enters the first area, and a control device configured to control an unlocking operation of the lock device, a closing operation of the striker device, a pop-up operation of the striker device, and switching on and off of the lamp. The control device switches on the lamp when the vehicle user is detected by the first human detection sensor and starts the controlling of the unlocking operation of the lock device and the closing operation and the pop-up operation of the striker device in response to the lamp being switched on.

摘要： A lighting module disclosed in an embodiment comprises: a plurality of light emitting devices on a substrate; and a reflector arranged in the direction of emission of light from each light emitting device on the substrate. The light emitting device has a light exit surface, and the reflector has a reflecting surface concave toward the substrate, at least a portion of the reflecting surface corresponding to the light exit surface of the light emitting device. The reflecting surface is arranged at a height that increases gradually in proportion to the interval from the light emitting device arranged in the light incident direction. The reflecting surface comprises a plurality of convex portions arranged in a first direction and first bridge portions that connect between the plurality of convex portions. The first bridge portions are arranged along the convex portions and are arranged to be lower than a straight line that connect high points of adjacent convex portions. The convex portions and the first bridge portions have the same length in a second direction, which is perpendicular to the first direction, and the area of the convex portions may be larger than the area of the first bridge portions.

摘要： Embodiments of the present invention relate to a lighting apparatus capable of providing three-dimensional effects at the same time as the surface emission of light sources by using a half-mirror member for reflecting and transmitting parts of light. In particular, by adopting the half-mirror member for transmitting a part of and reflecting another part of light emitted from a surface-emitting light source module, the present invention allows the implementation of a mirror-like image when the light is off, and allows the implementation of a light image providing various three-dimensional effects when the light is on.
