Embodiment Construction

[0011] Please refer to the accompanying drawings for the circuit composition and working principle of this device: the matrix coding switches K1-K18 are composed of light touch or induction 9-wire 3×6 matrix switches. The encoding processor IC1 (BL9148) is connected with the matrix switch. A steering flasher is composed of a 1 / 4LM324, a triode VT4, a relay Jz, a steering switch ZXK connected in series between the corresponding steering lamp control switch terminals, and a relay contact JZK. This circuit outputs a square wave signal about 75 times per second. , used to control the turn signal. Pin 15 of the encoding processor IC1 outputs a carrier signal, which can be sent to each decoder for deciphering. This example figure 2 Shown is a control unit with only one decoder. In actual use, two decoders at the front and rear can be set respectively, or four decoders at the left front, right front, left rear, and right rear can also be set respectively. The carrier signal is a...

Description

technical field [0001] The invention relates to a control device and method for a vehicle light. Background technique [0002] At present, lighting lamps and most electrical appliances of various high, medium and low-end models produced in various countries in the world adopt the high-current wire direct switch control method. Due to the complicated wiring harness, many high-current connectors, difficult wiring, and complex mechanical structure of the control switch, the contact resistance is often high due to oxidation, arcing, and mechanical structure failure, resulting in burned parts and out-of-control lighting. In severe cases, it may cause a fire or cause a traffic accident. After a breakdown or an accident, it is particularly difficult to overhaul and switch over, and even professionals cannot troubleshoot smoothly and quickly, which brings a lot of inconvenience to users. Contents of the invention [0003] The car lamp digital encoding and decoding one-line contr...
