Streamer tail light control circuit

Abstract

The invention discloses a streamer tail light control circuit. The streamer tail light control circuit comprises a front end input instruction end, a single chip microcomputer control end connected with the front end input instruction end, and a lamp bead driving end positioned on a lamp plate; the single chip microcomputer control end adopts an STC15W408AD single chip microcomputer; and front end input instruction end comprises a left steering instruction end connected with a P3.2INT0 port of the STC15W408AD single chip microcomputer, a right steering instruction end connected with a P3.3INT1 port of the STC15W408AD single chip microcomputer, and a clearance lamp instruction end connected with a P3.6INT2 port of the STC15W408AD single chip microcomputer. By virtue of the sectional type control structure, higher stability and reliability, relatively low loss rate, relatively low power consumption, and saving of a part of energy can be realized; and in addition, in installation, the lamp beads are mounted a PCB with width of less than 8.5mm, so that the overall structural width is relatively small, and the thickness is relatively thin, thereby realizing installation very conveniently.

Description

technical field [0001] The invention relates to the field of vehicle taillight control, in particular to a streamer taillight control circuit. Background technique [0002] Most of the existing vehicle taillights adopt more conventional linear taillights. When the taillights are operating left turn, right turn, position marker lights, and brake lights, the display forms of the taillights are too old-fashioned and not beautiful enough; and usually the brightness is not enough. , is not eye-catching enough, and does not meet the fashion pursuit of some young people; and when the linear taillights are operated, the driver chip drives a whole lamp to realize the conversion of each function of the taillights, the control is not precise enough, and the loss rate is large, power consumption Also relatively many, and the tail light lamp body of prior art is bigger and thicker, and the installation space of car body tail is less, is unfavorable for car lamp installation.
