Description

A DYNAMIC PROJECTION LAMP FOR ILLUMINATING A LIGHT FLUX AND A LIGHT PATTERNTECHNICAL FIELD

[0001] The present disclosure relates generally to the technical field of illuminating devices. In particular, it pertains to a simple, compact, and efficient dynamic projection lamp for illuminating a light flux and a light pattern.BACKGROUND

[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.

[0003] The conventional vehicle lamps primarily serve the purpose of illumination by offering limited means of illumination during the absence of lighting on the path of the vehicle or the ambient surroundings of the vehicle. As road safety requirements evolve and the need for improved communication between vehicles and pedestrians becomes increasingly critical in some instances where in low visibility conditions during night or adverse weather, the ability to effectively convey intentions and vital information to pedestrians and other vehicles is essential for overall road safety. Unfortunately, the conventional vehicle lamps and indicators relying on basic lighting mechanisms fall behind in providing comprehensive and intuitive communication cues, offering minimal insight into the vehicle's intentions or status.

[0004] Efforts to address the above constraints have been explored in a prior art. For instance, in patent document 20200377004, discloses an illumination of images around a vehicle. In this disclosure, illumination sources are positioned at predetermined locations on the vehicle, such as the door handles and front bumper. These installations involve additional components embedded into specific areas, resulting in increased packaging of these illuminating elements and additional costs. Furthermore, their functionality adds extra load to the vehicle's power source, such as the battery. However, there is a necessity to utilize the existing light flux available within the conventional vehicle lamps such that there is no additional need for packaging space and the load on the battery remains the same to generate images, integrating them within the existing framework.

[0005] There is, therefore, a requirement in the art to overcome the above-mentioned problems by providing a simple, compact, and efficient dynamic projection lamp for illuminating signs on a surface.OBJECTS OF THE PRESENT DISCLOSURE
