Description
Technical Field
[0001] This utility model relates to the field of projection and display device technology, and more specifically to a film projection and display device. Background Technology
[0002] Vehicle lighting systems are crucial for driving safety. Position lights are used to indicate the vehicle's outline, while turn signals indicate the vehicle's direction of travel; these are fundamental features for ensuring safe driving at night and in low-light conditions. Currently, motorcycles, ATVs, toy cars, and other motorized and non-motorized vehicles typically only have traditional position lights and turn signals at the front and rear of the vehicle. These functions are limited, their visual effect is limited, and they cannot provide effective illumination and warning to the sides and near the ground.
[0003] With the development of optical technology, projection lamp modules (such as projection modules based on MLA microlens arrays) have been applied in the automotive field, for example, for welcome light projection at car doors. However, such modules have complex structures and high costs, and their design is mainly used for static or low-speed opening of car doors. There is still no integrated and miniaturized lighting device suitable for special installation positions such as the ends of round handles on motorcycles and other vehicles, which can simultaneously perform multiple functions (such as ground pattern projection and side width indication). Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a film projection and width indication device that integrates a film projection module with a width indication light. This device not only projects ground patterns (such as width indication and turn signals) but also provides end width indication functionality, significantly improving driving safety and visual effects. Furthermore, it features a compact structure, convenient installation, attractive appearance, and wide applicability.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A film projection and display device includes an overall housing, a display lamp installed within the overall housing, and several film projection modules.
