It can create different atmospheres and experiences in the car, and enhance the comfort and fun of the driver and passengers. At present, car interior projection lamps have become a common configuration of many car brands.

[0003] Car interior projection lights have a wide range of applications. They can be used to illuminate the dashboard, center console, doors and other locations in the car, and can also be used to project various patterns or texts, such as car logos, brand logos, welcome messages, etc. In addition, some high-end models can also achieve functions such as voice interaction and navigation prompts through interior projection lights. In general, car interior projection lights enhance the visual experience in the car by creating unique lighting effects, and create a more comfortable and personalized driving environment for drivers and passengers.

[0004] Although automotive interior projection lights have many advantages in creating a unique atmosphere inside the car and enhancing the driving experience, there are also some technical disadvantages, as described below:

[0005] 1. Insufficient brightness: The existing car interior projection lamps have low brightness, especially in strong light environments, which will cause the projection effect to be unclear or disturbed;

[0006] 2. Projection angle limitation: Since the position of the projection lamp is usually fixed in a specific area, such as the roof, center console, etc., the projection effect cannot be clearly observed at positions other than a specific angle;

[0007] 3. Limited projection patterns: Current car interior projection lamps can mainly project some simple patterns, texts or logos, and it is difficult to achieve dynamic projection effects. Utility Model Content
