Abstract

An intelligent IoT active warning brake light and directional light assembly has a six-axis sensor, a radar unit, a lighting-emitting warning unit and a control device. The six-axis sensor measures a deceleration measurement and an inclination angle measurement for a traffic vehicle. The radar unit obtains a rear-vehicle deceleration measurement and the separation distance between the traffic vehicle and the rear vehicle. The control device makes the lighting-emitting warning unit actively emits a deceleration warning light and a steering warning light according to the deceleration measurement and the inclination angle measurement respectively. When the rear-vehicle deceleration measurement and the separation distance reach thresholds, the control device transmits an anti-collision indication and makes the lighting-emitting warning unit actively project towards the road to form a speed reduction warning pattern.

Description

The present invention relates to a lighting and warning device for a traffic vehicle, and in particular to a smart Internet of Things active warning brake light and turn signal light assembly.

The brake lights and turn signals are indicator light sources of a vehicle.
