[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are intended only to explain the relevant utility model and are not intended to limit the utility model. The embodiments described herein are merely a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort shall fall within the scope of protection of the present invention.

[0030] See also Figures 1 to 4 The example of this application discloses a dynamic lighting system including at least two light sources 200, a film 100 and at least two lenses 300, wherein at least two light sources 200 are located on the inner side of the film 100; at least two lenses 300 are located on the outer side of the film 100, and one lens 300, a film 100 and one light source 200 are arranged in a one-to-one correspondence to form an optical path, at least one of the at least two optical paths is a compensation optical path, and at least one is a projection optical path; when the film 100 rotates around its own axis, the at least two optical paths appear alternately to form a dynamic projection.

[0031] In the dynamic lighting system of the present invention, at least one of the at least two light paths is a compensation light path, and at least one is a projection light path; when the film 100 rotates around its own axis, at least two light paths appear alternately to form a dynamic projection. When switching scenes, brightness compensation is performed to achieve dynamic fill light, reduce the visual difference when switching between frames, and combine with other projection parts to achieve a smooth dynamic effect, thereby improving the viewing experience.

[0032] It should be noted that the fill light path mainly provides auxiliary lighting function, performs brightness compensation when the film switches scenes, and realizes dynamic fill light; the projection light path provides dynamic projection content, including but not limited to breathing, strobing, bright and dark light source 200 movements.

[0033] In this example, the film 100 is divided into an inner side and an outer side, with the light source 200 positioned on the inner side and the lens 300 on the outer side. Furthermore, to improve projection clarity, a collimator 400 is positioned between the light source 200 and the film 100. The collimator 400 constrains the light from the light source 200 to a certain divergence angle before irradiating the film 100.

[0034] The light source 200 can be arranged separately or can be set on the circuit board 500 and integrated with the circuit board 500, which can reduce the number of parts and reduce the difficulty of assembly.

[0035] In some examples of the present application, the light source 200 includes lamp beads of at least one color, which may be LED lamp beads or incandescent lamps.

[0036] The film 100 can rotate about its own axis, thereby enabling projection of different frames on the film 100. In some examples, the film 100 is driven to rotate about its own axis by a motor 600. Because the film 100 is directly driven by the motor 600, the shaking caused by the installation of transmission parts can be reduced, thereby reducing the occurrence of jumps.

[0037] Specifically, the output shaft of the motor 600 is directly connected to the connecting frame 700 of the film 100. The rotating shaft and the connecting frame 700 are interference-fitted or connected via an adhesive. The connecting frame 700 and the film 100 are connected using a special-shaped hole or adhesive. Any structure that can drive the film 100 to rotate is within the scope of protection of this utility model.

[0038] In order to further reduce the volume of the system, the output shaft of the motor 600 passes through the circuit board 500 , thereby reducing the space occupied by the overlapping of the circuit board 500 and the output shaft of the motor 600 .

[0039] In some embodiments, the circuit board 500 is electrically connected to the light source 200 and the motor 600 to control the switching of the light source 200, brightness adjustment, speed of the motor 600, and selection of projection content.

[0040] In some embodiments, the film 100 includes at least two frames, each of which includes multiple frames arranged in a circular pattern. All frames are arranged according to a predetermined pattern, with projection areas and fill-light areas. The light source 200 passes through the projection area and, in conjunction with the lens 300, forms a projection optical path for projection. The light source 200 passes through the fill-light area and, in conjunction with the lens 300, forms a fill-light optical path for fill-light.

[0041] For example, a film sheet 100 includes two rings of frames: an inner ring 120 and an outer ring 110. Each ring includes multiple frames arranged in a circular pattern. In some examples, one ring of frames contains only a projection area, while the other contains only a fill light area. Thus, during rotation, the film sheet 100 performs only projection or only fill light on the same ring of frames. For both rings of frames, one ring of frames performs projection while the other performs fill light. Light source 200 projects a pattern through the projection area in conjunction with lens 300, while light source 200 performs fill light through the fill light area in conjunction with lens 300. In another example, each ring of frames alternates between a projection area and a fill light area. Thus, during rotation, the film sheet 100 performs both projection and fill light sequentially on the same ring of frames. For both rings of frames, one ring of frames performs projection while the other performs fill light.

[0042] In the frames located in the outer circle 110 , the angle between each two adjacent frames is a; in the frames located in the inner circle 120 , the angle between each two adjacent frames is b, where b=2a.

[0043] It should be noted that pattern 110 includes text and / or images. The number of frames can be two or more. The diagram discloses a two-circle structure, with the outer circle 110 located on the outside and the inner circle 120 located on the inside. The outer circle 110 includes 16 frames, with the angle between each two adjacent frames being 22.5°. The inner circle 120 includes 8 frames, with the angle between each two adjacent frames being 45°.

[0044] The outer circle 110 starts from the 9 o'clock position and goes clockwise as follows: the first frame, the second frame, the third frame, the fourth frame, the fifth frame, the sixth frame, the seventh frame, the eighth frame, the ninth frame, the tenth frame, the eleventh frame, the twelfth frame, the thirteenth frame, the fourteenth frame, the fifteenth frame, and the sixteenth frame. The inner circle 120 starts from the 9 o'clock position and goes clockwise as follows: the first frame, the second frame, the third frame, the fourth frame, the fifth frame, the sixth frame, the seventh frame, and the eighth frame.

[0045] To achieve continuous dynamic projection, the overall animation can be broken down into several patterns, each numbered sequentially according to the animation sequence, for example, 1, 2, 3, etc. To improve smoothness, when one circle of frames is projected and another circle of frames is used for fill light, the projection area in the outer circle 110 is sequentially arranged with the odd-numbered patterns of the overall animation decomposition pattern, while the projection area in the inner circle 120 is sequentially arranged with the even-numbered patterns of the overall animation decomposition pattern.

[0046] The frames on the outer circle 110 correspond to the first, third, fifth, seventh, ninth, eleventh, thirteenth and fifteenth patterns of the decomposition pattern of the entire animation, with each alternate frame corresponding to the first, third, fifth, seventh, ninth, eleventh, thirteenth and fifteenth patterns.

[0047] The frames on the inner circle 120 correspond to the 2nd pattern, the 4th pattern, the 6th pattern, the 8th pattern, the 10th pattern, the 12th pattern, the 14th pattern, and the 16th pattern of the overall animation decomposition pattern.

[0048] In order to determine the initial position, a position sensor is also included. When the film 100 is at the initial position, the position sensor generates a response signal. The position sensor can be of infrared photoelectric, Hall or other types.

[0049] In some embodiments, the circuit board 500 controls the switching and brightness adjustment of the light source 200 and the operation of the motor 600 .

[0050] See also Figures 5 to 13 , this application also discloses the installation process of the above-mentioned dynamic lighting system.

[0052] The first bracket 810 is used to support the motor 600, the motor 600, the circuit board 500, the collimator 400, the connecting frame 700, the film 100 and the second bracket 820. The second bracket 820 is clamped on the side of the first bracket 810;

[0053] The base 910 is used to support the bracket assembled with the support motor 600, the motor 600, the circuit board 500, the collimator 400, the connecting frame 700, the film 100 and the second bracket 820;

[0054] The mask 920 is integrally mounted on the base 910 to enclose the motor 600, the first bracket 810, the circuit board 500, the collimator 400, the connecting frame 700, the film 100, the second bracket 820 and the lens 300 in the space between the two to protect the safety of the internal components.

[0055] It should be noted that the lens 300 can be installed separately at a corresponding position outside the film 100. In the example of the present application, the lens 300 is arranged outside the film 100 through a pressure plate cover.

[0056] The present application provides a dynamic lighting method, which uses any of the above-mentioned dynamic lighting systems. The lighting method includes:

[0057] The rotating film 100 rotates at a preset speed and at least two light sources 200 are alternately lit for a preset time, so that at least two light paths appear alternately to form a dynamic projection.

[0058] Below, the film 100 includes two frames, an inner circle 120 and an outer circle 110 , the light source 200 includes a first light source 200 and a second light source 200 , and the lens 300 includes a first lens 300 and a second lens 300 , and the action is decomposed. Specifically, it includes:

[0059] Action 1: The motor 600 drives the film 100 to the starting position. At this time, the first lens 300 is aligned with the first frame on the outer ring 110.

[0060] Action 2: Light up the first light source 200 for less than 0.8 seconds. At the same time, the motor 600 drives the film 100 to rotate a certain angle, and the second lens 300 is aligned with the first frame of the inner circle 120.

[0061] Action 3: Light up the second light source 200 for less than 0.8 seconds. At the same time, the motor 600 drives the film 100 to rotate a certain angle, and the first lens 300 is aligned with the third frame of the outer ring 110.

[0062] Working alternately in sequence, the projection switching time of continuous actions is minimized to ensure the smoothness of dynamic effects. The circuit board 500 of this application needs to drive the motor 600 in real time to coordinate with the light source 200. The motor 600 rotates according to the established rules, speed, and direction according to the requirements of the dynamic effect. During the rotation of the motor 600, the light source 200 needs to cooperate with its driving brightness and frequency control respectively to achieve breathing, stroboscopic, bright and dark light source 200 actions, thereby achieving a dynamic effect without dragging, abnormal flickering, and high brightness. The full response time must be controlled within 5ms. At this time, the control of the motor 600 must be planned according to the dynamic content of the film, and the response time must be controlled within 15ms to ensure the dynamic effect.

[0063] The present application provides a vehicle including any of the above-mentioned continuous dynamic film projection systems 100. Since the above-mentioned continuous dynamic film projection system 100 has the above-mentioned beneficial effects, the vehicle including the continuous dynamic film projection system 100 has corresponding effects, which will not be described in detail here.
