The invention discloses an auxiliary brake lamp. An existing automobile brake lamp is single in form, and deceleration or emergency brake cannot be distinguished. A data line and a control line of anacceleration sensor are connected with a single-chip microcomputer, and a power supply module supplies power to internal circuits of a multi-channel electromagnetic relay module, a power supply acceleration sensor and the single-chip microcomputer. And a plurality of signal input ends of the multi-channel electromagnetic relay module are correspondingly connected with a plurality of signal outputpins of the single chip microcomputer. One end of each LED lamp is connected with a normally open end of the corresponding electromagnetic relay, the common end of each electromagnetic relay is connected with one end of the power supply, and the other end of the power supply is connected with the other end of each LED lamp. The single-chip microcomputer controls on and off of the LED lamps throughthe multiple electromagnetic relays. The acceleration sensor is used for monitoring an automobile speed change in real time, the corresponding LED lamps are controlled to be turned on and off according to the acceleration, warning is provided for rear automobiles, and deceleration or emergency brake is displayed. The auxiliary brake lamp is a good supplement to an existing single-mode brake lamp.

    本发明公开了一种辅助刹车灯。现有汽车刹车灯形式单一,不能区分减速或急刹。本发明中加速度传感器的数据线和控制线接单片机,电源模块为多路电磁继电器模组的内部电路,以及供电加速度传感器和单片机供电。多路电磁继电器模组的多个信号输入端分别对应接单片机的多个信号输出脚。多个LED灯的一端接对应多路电磁继电器的常开端,各路电磁继电器的公共端接电源的一端,电源的另一端接LED灯的另一端。单片机通过多路电磁继电器控制多个LED灯的开关。本发明通过加速度传感器实时监测汽车速度变化,根据加速度控制相应的LED灯的开关,为后方车辆提供警示,显示减速还是急刹。本发明是对现有单一模式刹车灯的很好补充。
