Description

Automobile welcome lamp

Technical Field

The utility model relates to the technical field of lighting fixtures, concretely relates to car usher lamp.

Background

The automobile welcome lamp is usually arranged below doors on the main and auxiliary driving sides of an automobile or in the left and right outer rearview mirrors. When the doors of the main driving side and the auxiliary driving side are opened, the welcome lamp device can project logo patterns, characters and the like of the vehicle on the ground.

The existing welcome lamp is a novel green welcome lamp for vehicles, and is mainly installed at the position of a vehicle door of a vehicle at present. The purpose of arranging the welcome lamp is to provide good illumination for the ground at the position of a vehicle door for people getting on and off the vehicle and avoid stepping on sand, soil, rainwater, pit bags and the like except for safety consideration and humanization requirements. For example, when a user sits in the vehicle at night, the user can step on a mud bar to get on the vehicle when the user gets on the vehicle and the user fails to see the road clearly. In addition, the important thing is that the light prompt is sent out after the vehicle is parked and the door is opened, so that rear-end collision and scraping of the vehicle behind can be avoided.

At present car usher lamp is mostly controlled through magnet sensor, and magnet sensor receives the influence of temperature, humidity big to lead to the control effect of sensor poor, the accuracy is low, and intelligent degree is low.

In summary, there is a need for an automotive greeting lamp.
