Embodiment Construction

[0012] New lighting car welcome lights, including:

[0013] The first control unit is configured to receive the first pulse width modulation signal sent by the controller, and control the magnitude of the first current input to the R terminal of the three-color LED light source by adjusting the duty cycle of the first pulse width modulation signal ;

[0014] The second control unit is configured to receive the second pulse width modulation signal sent by the controller, and adjust the duty cycle of the second pulse width modulation signal to control the second current input to the terminal G of the three-color LED light source to control the size of

[0015] The third control unit is configured to receive the third pulse width modulation signal sent by the controller, and adjust the duty ratio of the third pulse width modulation signal to control the third current input to the terminal B of the three-color LED light source The size is controlled.

[0016] The first control ...

Abstract

The invention relates to the technical field of automobile lighting, in particular to a novel lighting automobile welcome lamp. The invention provides a control circuit of an automobile welcome lamp and an automobile welcome lamp. The first control unit, the second control unit and the third control unit respectively receive the first pulse width modulation signal, the second pulse width modulation signal and the third pulse width modulation signal from the controller. When the modulation signal is in a low level state, the three-color LED light source does not emit light. When the modulated signals are in the positive pulse width state, the magnitude of the current flowing through the R, G and B terminals can be controlled by adjusting the duty cycle of the modulated signals, so that theluminous color of the three-color LED light source can be controlled. It can be seen that the control circuit of the automobile welcome lamp and the automobile welcome lamp provided by the invention can realize the projection of the welcome patterns of different colors and greatly improve the display effect of the welcome lamp.

Description

technical field [0001] The invention relates to the technical field of automobile lighting, in particular to a novel lighting automobile welcome lamp. Background technique [0002] Fine particulate matter is also called fine particles, fine particles, PM2.5. Fine particulate matter refers to particulate matter in the ambient air with an aerodynamic equivalent diameter less than or equal to 2.5 microns. It can be suspended in the air for a long time, and the higher its concentration in the air, the more serious the air pollution. Although PM2.5 is only a small component of the earth's atmospheric composition, it has an important impact on air quality and visibility. Compared with coarser atmospheric particles, PM2.5 has a small particle size, large area, strong activity, and is easy to attach toxic and harmful substances (such as heavy metals, microorganisms, etc.), and has a long residence time in the atmosphere and a long transportation distance. Therefore, it has a grea...
