Abstract

The invention provides a control circuit of controlling the illumination brightness of a bicycle according to the bicycle speed. Through detecting the running speed of a bicycle, the illumination state of a lamp on the bicycle is controlled. The control circuit comprises a speed detection unit, a speed and brightness converting circuit, a lamp brightness adjusting circuit and a drive circuit. The speed detection unit is used for detecting the speed of the running bicycle and producing a speed signal. The speed and brightness converting circuit connects the speed detection unit and generates a conversion signal according to the speed signal. The lamp brightness adjusting circuit connects the speed and brightness converting circuit and produces a brightness adjusting signal according to the conversion signal. The drive circuit connects the speed and brightness converting circuit and adjusts the brightness of the lamp according to the brightness adjusting signal.

Description

technical field [0001] The invention relates to the design of a control circuit, in particular to a control circuit for controlling the illumination brightness of a riding vehicle according to the speed of the vehicle. Background technique [0002] In a modern society where oil prices are constantly rising, most people have gradually reduced the frequency of driving out. In recent years, the important topic of energy saving and carbon reduction has been paid attention to by people, and there are many options for transportation to and from get off work. People have selected more fuel-efficient locomotives, electric locomotives or bicycles and other riding vehicles as means of transportation. Especially bicycles, not only can be used as a means of transportation on weekdays, but also a kind of leisure sport on weekends and holidays. [0003] But, on general bicycle structural design, because bicycle itself is not designed with the lighting equipment of headlight in the front p...
