Description

Active guiding reflector

The invention relates to an active guiding and reflecting device, in particular to an active guiding and reflecting device for sensing the orientation of a vehicle light source through a plurality of photosensitive units and automatically guiding according to the orientation of the light source.

The conventional reflectors are placed in a fixed way on the corners of the road, and need to be set at a fixed angle to enable the two-way vehicle on the road to know the direction of the road turning through the conventional reflectors, so as to avoid the lack of sight. The direction of the road turning makes the driver of the vehicle unable to turn because the speed is too fast, thus causing a traffic accident.

Since the conventional reflector is set for a long time, it is exposed to the open air. After the wind, the sun, the rain, the reflective effect will gradually deteriorate, and the conventional reflector is fixed, unable to follow the movement of the vehicle and actively guide the reflection. The reflectors are also unable to adjust the angle of reflection. The light projected by the vehicle is directed to a farther place. When the light projected by the vehicle is weak, it is also impossible for the vehicle driver on the road to know the turning of the road through the conventional reflector. Direction, and the conventional reflector provides only a single direction of reflection, can not be reflected according to the direction of the light, then adjust the direction to reflect, and remind the driver of the vehicle on the road, and the conventional reflector itself does not have a spontaneous light source, therefore, when When the driver drives the vehicle, it is possible to see the conventional reflector when approaching the corner of the lane and present the road conditions at the corner of the lane through the conventional reflector. At this time, the driver will make the road according to the road conditions he sees. When the reaction occurs, it may be caused by a slow reaction, which may cause a traffic accident.
