This invention relates to the field of vehicle lighting technology, specifically to an intelligent light-sensing system for adaptively switching visibility distance in high-speed train headlights. In this embodiment, the dynamic visibility distance calculation module calculates the target visibility distance in real time based on collected environmental and train operating status parameters. This allows the system to flexibly adjust the headlight illumination range according to actual conditions, effectively avoiding safety risks caused by insufficient visibility. The fuzzy control module utilizes a fuzzy logic algorithm, combined with target visibility distance and environmental parameters, to output headlight control commands, precisely adjusting the headlight's illumination angle, color temperature, and light intensity level. Compared to traditional fixed parameter settings or simple adjustment methods, the fuzzy logic algorithm can handle the fuzziness and uncertainty of environmental factors, achieving refined and adaptive adjustment of headlight illumination parameters.

The utility model discloses a purification structure, include: mounting seat, purification main part and fan parts, mounting seat is connected with magnet, mounting seat is connected with support rod, and support rod extends along the axial direction of mounting seat, purification main part is equipped with the gas inlet, purification cavity and gas outlet that communicate in proper order, and purification main part still is equipped with the installation mouth that communicates with purification cavity, and the filter core is arranged in the purification cavity, and the filter core is detachably installed in the purification cavity, the mounting seat is detachably installed in the installation mouth, and makes support rod abuts filter core, to prevent filter core from falling off from installation mouth, and fan parts are installed in the purification cavity. The effective solution has replaced the filter core when the current purification structure, and the process is more tedious problem. The utility model discloses still a kind of vehicle-mounted lamps, include: lamps and lanterns and the purification structure of the kind described above, lamps and lanterns are installed in purification main part, and lamps and lanterns have switch, and gas outlet is towards lamps and lanterns. The effective solution has the problem that the current vehicle-mounted lamps need frequent cleaning.

To provide a lighting system, a control device, a lighting fixture, and a vehicle that can wirelessly control the timing of dimming multiple lighting fixtures.SOLUTION: A lighting system according to an embodiment of the present invention includes a control device and a plurality of lighting fixtures. The control device wirelessly transmits a dimming control signal a plurality of times at a predetermined time interval. The plurality of lighting fixtures receive a dimming control signal. The dimming control signal includes transmission count information indicating the number of times the dimming control signal has been transmitted, and each of the plurality of lighting fixtures includes a light-emitting unit and a light emission timing control unit that controls the timing of emitting light from the light-emitting unit on the basis of the transmission count information.SELECTED DRAWING: Figure 1

The utility model relates to a kind of reading lamps for vehicle seat, it includes lamp body, lamp holder and the rotating adjusting mechanism connected between the both, the rotating adjusting mechanism is set to include parallel rotation shaft assembly rotatably connected on lamp holder, and vertical rotation shaft assembly rotatably connected on parallel rotation shaft assembly at one end while the other end is fixed on lamp body, so that lamp body can be angle adjusted in vertical and parallel two directions relative to lamp holder.The utility model can control lamp body along up-down direction and left-right direction rotation adjusting lamp body angle, realize the angle rotation adjustment of lamp body in certain angle range.

To provide an illumination system capable of communicating with an adjacent railroad vehicle or a tail-end railroad vehicle in wireless communications, a control device, a lighting fixture, and a vehicle.SOLUTION: An illumination system comprises: a first lighting fixture provided in a first vehicle for receiving a signal transmitted from a control device; a first relay provided in the first vehicle for receiving the signal transmitted from the control device or the first lighting fixture; and a second lighting fixture provided in a second vehicle connected to the first vehicle. The first relay transmits the received signal to the second vehicle. Thus, communications with an adjacent railroad vehicle or to a tail-end railroad vehicle in wireless communications can be performed.SELECTED DRAWING: Figure 1
