Description

Technical Field

[0002] The welcome light (also known as the ground light) is used as auxiliary lighting and can be used for ground lighting or route lighting under low ambient light. The welcome light includes an LED light, a pattern module designed with a pattern, and an imaging module that projects the pattern on the ground or wall. Its working principle is: the light emitted by the LED light passes through the pattern module, and the shape of the pattern is projected out in the shape of light from the imaging module to form a light pattern on the ground. For example, the welcome light used in a car is usually installed in a position such as a door or a rearview mirror. When the door is opened, the lighting function will be turned on and the image will be projected on the ground, which not only produces a unique and dazzling image light and projection image, but also provides the function of illuminating the ground when the door is opened under low ambient light at night, so that people getting on and off the car can pay attention to the ground condition and will not accidentally step on the dirt, puddles, or other dangerous terrain on the ground. The welcome light in the prior art can usually only display a logo pattern or text, only a single welcome mode, and can only be used in a single scene, which cannot meet the needs of users; and the projected light spot has obvious color difference, which affects the user experience; at the same time, the overall length is long and occupies a large space.
