DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It will be understood that the specific embodiments described herein are only used to explain the relevant inventions, rather than to limit the invention. The described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0023] See also Figures 1 to 4 The example of the present 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, a lens 300, a film 100 and a 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, at least two optical paths appear alternately to form a dynamic projection.

[0024] 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, and when switching scenes, brightness compensation is performed to achieve dynamic fill light, reduce the visual dark difference when switching between frames, and combine with other projection parts to achieve a smooth dynamic effect and enhance the viewing experience.

[0025] It should be noted that the fill light path mainly provides auxiliary lighting function, and performs brightness compensation to achieve dynamic fill light when the film switches scenes; the projection light path provides dynamic projection content, including but not limited to breathing, strobing, bright and dark light source 200 movements.

[0026] In the example of the present application, the film 100 is divided into an inner side and an outer side, wherein the light source 200 is arranged on the inner side and the lens 300 is arranged on the outer side. In addition, in order to improve the clarity of the projection process, a collimator 400 is arranged between the light source 200 and the film 100. The function of the collimator 400 is to constrain the light of the light source 200 to a certain divergence angle and irradiate the film 100.

[0027] The light source 200 may be arranged separately, or may be disposed on the circuit board 500 and integrated with the circuit board 500 , thereby reducing the number of components and lowering the difficulty of assembly.

[0028] In some examples of the present application, the light source 200 includes lamp beads of at least one color. The lamp beads may be LED lamp beads or incandescent lamps.

[0029] The film 100 can rotate around its own axis, thereby enabling projection of different frames on the film 100. In some examples, the film 100 is driven to rotate around its own axis by the motor 600. Since the film 100 is directly driven to rotate by the motor 600, the shaking caused by the setting of the transmission parts can be reduced, thereby reducing the occurrence of jumping.

[0030] Specifically, the output shaft of the motor 600 is directly connected to the connecting frame 700 of the film 100, and the rotating shaft is interference fit with the connecting frame 700, or connected by an adhesive. The connecting frame 700 and the film 100 are connected by a special-shaped hole, or connected by an adhesive. As long as the structure can drive the film 100 to rotate, it is within the protection scope of the present invention.

[0031] 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 .

[0032] 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, rotation speed of the motor 600, and selection of projection content.

[0033] In some embodiments, the film 100 includes at least two circles of frames, wherein each circle of frames includes a plurality of frames arranged in a circle, and all frames are arranged with a projection area and a fill light area according to a preset rule. The light source 200 passes through the projection area and cooperates with the lens 300 to form a projection optical path to achieve projection, and the light source 200 passes through the fill light area and cooperates with the lens 300 to form a fill light optical path to achieve fill light.

[0034] Take the film 100 as an example, which includes two circles of frames, namely the inner circle 120 and the outer circle 110, and each circle includes multiple frames arranged in a circle. In some examples, one circle of frames is only arranged with a projection area, and the other circle of frames is only arranged with a fill light area. In this way, during the rotation of the film 100, for the same circle of frames, only projection or only fill light is performed; for the two circles of frames, one circle of frames is projected, and the other circle of frames is fill light. The light source 200 can realize the projection of the pattern through the projection area in cooperation with the lens 300, and the light source 200 can realize the fill light through the fill light area in cooperation with the lens 300. In another example, each circle of frames is alternately arranged with a projection area and a fill light area. In this way, during the rotation of the film 100, for the same circle of frames, projection and fill light can be performed in sequence; for the two circles of frames, when one circle of frames is projected, the other circle of frames is fill light.

[0035] 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.

[0036] It should be noted that the pattern 110 includes text and / or pictures. The number of circles of the frame can be two or more circles. The diagram discloses a two-circle structure, the outer circle 110 is located on the outside, and the inner circle 120 is located on the inside. The outer circle 110 includes 16 frames, and the angle between each two adjacent frames is 22.5°. The inner circle 120 includes 8 frames, and the angle between each two adjacent frames is 45°.

[0037] The outer circle 110 starts from the nine o'clock direction and goes clockwise to include 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 nine o'clock direction and goes clockwise to include 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.

[0038] In order to achieve continuous dynamic projection, the overall animation can be decomposed into several patterns, and they are numbered in sequence according to the animation sequence, such as 1, 2, 3... In order to improve the fluency, when one circle of frames is projected and another circle of frames is used for fill light, the projection area located in the outer circle 110 is sequentially arranged with odd-numbered patterns of the overall animation decomposition pattern, and the projection area located in the inner circle 120 is sequentially arranged with even-numbered patterns of the overall animation decomposition pattern.

[0039] The frames on the outer circle 110 correspond to the 1st pattern, the 3rd pattern, the 5th pattern, the 7th pattern, the 9th pattern, the 11th pattern, the 13th pattern and the 15th pattern of the overall animation decomposition pattern at every other frame.

[0040] 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.

[0041] 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.

[0042] 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 .

[0043] See also Figures 5 to 13 , the application also discloses the installation process of the above-mentioned dynamic lighting system.

[0046] It should be noted that the above-mentioned lens 300 can be separately installed at a corresponding position outside the film 100. In the example of the present application, the lens 300 is arranged on the outside of the film 100 through a pressure plate cover.

[0047] The present application provides a dynamic lighting method, the lighting method uses any of the above-mentioned dynamic lighting systems, and the lighting method includes: The rotating film 100 rotates at a preset speed and at least two light sources 200 are alternately lit for a preset time, and at least two light paths appear alternately to form a dynamic projection.

[0048] Hereinafter, the film 100 includes two frames of the inner circle 120 and the outer circle 110, the light source 200 includes the first light source 200 and the second light source 200, and the lens 300 includes the first lens 300 and the second lens 300, and the action is decomposed, specifically, including: Action 1: The motor 600 drives the film 100 to be positioned at the starting position, at which time the first lens 300 is aligned with the first frame on the outer ring 110; Action 2: Light up the first light source 200 for less than 0.8 seconds, and 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; 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 .
