Abstract

The invention discloses a guest welcoming lamp of an automobile. The guest welcoming lamp of the automobile comprises a light source with at least two color light emitting ends, a photographic film used for projecting emergent light of the light source into guest welcoming patterns, a first lens set used for projecting the guest welcoming patterns to the ground, a controller used for monitoring the automobile door opening and closing state of the automobile in real time and sending pulse width modulation signals corresponding to the color light emitting ends and having different duty ratios when an automobile door is in an opened state, and a color control circuit adjusting the color of the light source according to the pulse width modulation signals having different duty ratios. Because the light emitting ends of different colors correspond to the pulse width modulation signals having different duty ratios, the pulse width modulation signals having different duty ratios make current passing through the light emitting ends, of different colors, of the light source different, the color of the guest welcoming patterns is the most changeful, the display effect is rich and colorful, and the diversity of the guest welcoming patterns is improved.
