Abstract

The invention provides an intelligent signal lamp for automobiles comprising a MCU and a LED lattice. The LED lattice is composed of a plurality of high brightness LEDs integrating three colors of red, yellow and green. Each LED which is a high brightness LED sold in markets is connected with an I / O interface of the MCU and is arranged in the sequence of red, yellow and green from left to right on the tailstock of a vehicle. The acquired speed signals are input into the MCU, analyzed and judged by the MCU to control LED display, thereby vehicle speeds are displayed in real time. The vehicle speed is displayed by the colors and numbers of the LEDs, and the LEDs can also be used with a high position braking lamp in combination. The inventive intelligent signal lamp is provided with low power consumption, high reliability and intelligentization, shortens vehicle following distance, and reduces rear collision probability. Low production cost and large market potential are also provided.

Description

[0001] Field: [0002] The invention relates to an automotive lamp, in particular to an intelligent automotive signal lamp. Background technique: [0003] Car lamps are mainly divided into lighting lamps and signal lamps according to their functions. Lighting fixtures illuminate driving roads, traffic signs, other vehicles, pedestrians, etc. Signal lamps are to show the existence of the vehicle and convey the information of the vehicle's driving state. [0004] In the prior art, the vehicle speed is displayed for oneself, but it is difficult for other road users to estimate their own vehicle speed, especially when everyone is driving at a high speed. This will cause inconvenience to the operation of the driver behind. When there is heavy fog, it is difficult for other road users to determine the presence and driving status of vehicles on the road ahead. Summary of the invention: [0005] The purpose of the present invention is to make the driver safer when driving a motor vehicle ...
