Abstract

The present invention discloses a control circuit for a vehicle welcome light and the vehicle welcome light. The control circuit comprises a first control unit used for receiving a first pulse width modulated signal sent by a controller and controlling the size of a first current input into the R end of a three-color LED light source by regulating the duty cycle of the first pulse width modulated signal, a second control unit used for receiving a second pulse width modulated signal sent by the controller and controlling the size of a second current input into the G end of the three-color LED light source by regulating the duty cycle of the second pulse width modulated signal and a third control unit used for receiving a third pulse width modulated signal sent by the controller and controlling the size of a third current input into the B end of the three-color LED light source by regulating the duty cycle of the third pulse width modulated signal. According to the control circuit and the vehicle welcome light disclosed by the invention, the display effect of the vehicle welcome light is greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of automobile lighting, in particular to a control circuit of an automobile welcome lamp and the automobile welcome lamp. Background technique [0002] The car welcome light is usually installed under the door of the owner and passenger side of the car or in the left and right side exterior mirrors. When the doors on the driver's and passenger's sides are opened, the welcome light device can project the vehicle's logo pattern, text, etc. on the ground. Most of the existing welcome lights display a static logo pattern with a single display color and poor effect. Contents of the invention [0003] The object of the present invention is to provide a control circuit of a car welcome light and a car welcome light, aiming at solving the problem of poor display effect of the existing car welcome light. [0004] In order to solve the above-mentioned technical problems, the present invention provides a control ci...
