Description

Technical Field

[0001] This invention relates to the field of lighting technology, and more specifically to a device for generating abstract light textures through dynamic reflection. Background Technology

[0002] Stage performances and nighttime cityscapes of urban media facades often require displays, digital projectors, and dot matrix screens to show abstract and changing light spot effects, enhancing the content and aesthetic appeal of the program.

[0013] The beneficial effect of adopting the above technical solution is that, in this invention, light enters from the waterproof glass, and the position of the reflective concave-convex mirror is adjusted by the vertical moving component and the horizontal moving component. At the same time, the path of the light can be changed by the concave-convex surface of the reflective concave-convex mirror, so that the reflected light has a dynamic light band texture.

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] This invention discloses an apparatus for generating abstract light textures through dynamic reflection, comprising:

[0053] The main body of the chassis 1 has a waterproof glass 2 at the light incident end;

[0054] The reflective concave-convex mirror 3 is disposed inside the main body 1 of the chassis;

[0055] The vertical moving assembly 4 includes: a lifting plate 41, a rack 42, a gear 43, a motor 44, and a motor fixing plate 45; the lifting plate 41 is placed inside the main body 1 of the chassis, one end of the lifting plate 41 is hinged to the inner wall of the main body 1 of the chassis, and the other end is fixedly connected to the rack 43; the motor 44 is fixedly connected to the motor fixing plate 45; the output end of the motor 44 is connected to the gear 43, and the gear 43 meshes with the rack 42 for transmission, and the rack 42 drives the end of the lifting plate 41 to move up and down;

[0056] The lateral movement component 5 includes: a fixed plate 51, a sliding rod 52, a baffle 53, a swing wheel 54, and a swing drive motor 55; a reflective concave-convex mirror 3 is disposed on the top of the fixed plate 51; the swing drive motor 55 is fixed to the top of the lifting plate 41, and the output end of the swing drive motor 55 is connected to the swing wheel 54, the top of the swing wheel 54 is connected to an eccentric shaft 56; the baffle 53 is fixed to both ends of the lifting plate 41, one end of the sliding rod 52 is connected to the end of the fixed plate 51, and the other end passes through the baffle 53 and is slidably connected to the baffle 53; an oblong hole 57 is provided at the position corresponding to the position of the baffle 53 and the eccentric shaft 56, and the eccentric shaft 56 passes through the oblong hole 57. In this invention, the reflective concave-convex mirror 3 is generally a bright stainless steel plate, but it can also be other metal materials or resin materials that are produced and then coated; the richness of color can be increased by the surface color layer and coating layer of the reflective concave-convex mirror 3, which can be a single-thickness monochromatic coating or a multi-colored coating with gradient thickness.

[0057] To further optimize the above technical solution, a cover 6 is provided on one side of the chassis body 1 where the waterproof glass 2 is located. The cover 6 is arranged at an angle. A first glass slot 61 for placing the waterproof glass 2 is opened on the surface of the cover 6. The device of the present invention does not contain a light source, and the overall heat is greatly compressed. The temperature rise inside the device is very low, and the temperature difference between the inside and outside of the waterproof glass is very low, which can effectively avoid the problem of condensation on the inner surface, which would cause the target light spot texture to become distorted. The chassis body 1 is generally made of QR235 sheet metal or 6063 aluminum, and the outer surface needs to be treated with anti-corrosion.

[0058] To further optimize the above technical solution, a waterproof gasket 7 is provided on the side of the front cover 6 near the interior of the chassis body 1. An annular groove 71 is provided on the inner wall of the waterproof gasket 7, and the waterproof glass 2 is placed in the annular groove 71. The waterproof gasket 7 forms a sealed structure to prevent rainwater from entering.

[0059] To further optimize the above technical solution, a waterproof pressure plate 8 is provided on the side of the waterproof rubber ring 7 away from the face cover 6, and a second glass groove 82 is provided at the position of the waterproof pressure plate 8 corresponding to the first glass groove 61; the waterproof pressure plate 8 is connected to the face cover 6.

[0060] To further optimize the above technical solution, a reflective concave-convex mirror fixing block 58 is provided at the bottom of the fixing plate 51, and the sliding rod 52 is slidably connected to the reflective concave-convex mirror fixing block 58.

[0061] To further optimize the above technical solution, a rotating support block 9 is provided inside the main body 1 of the chassis. A hinge 10 is connected to the top of the rotating support block 9, and the other end of the hinge 10 is connected to the lifting plate 41.

[0062] To further optimize the above technical solution, the main body 1 of the chassis houses a power supply 11 and a control circuit board 12. Both the motor 11 and the swing drive motor 55 are connected to the control circuit board 12. The motor 44, control circuit board 12, and swing drive motor 55 are all connected to the power supply 11. The power supply 11 is generally a wide-voltage switching power supply, capable of providing a stable DC 12V or 24V output from a 100-240V input, powering the control circuit board and motor 44. The control circuit board 12 is used for autonomously programming the movement direction, speed, and running time of the motor 44, and also for receiving external DMX signals and accurately responding to them.

[0063] To further optimize the above technical solution, a motor receiving groove 46 is provided on the surface of the lifting plate 41; a motor fixing plate 45 is inserted into the motor receiving groove 46; the rack 42 and the gear 43 are both placed in the motor receiving groove 46; a rack fixing block 47 is provided on the side wall of the rack 42, and the rack fixing block 47 is connected to the lifting plate 41.

[0064] To further optimize the above technical solution, a Hall plate 13 is provided on the side of the motor mounting plate 45 near the rack 42, and a magnet 48 is provided at the corresponding position of the rack 42 and the Hall plate 13. The Hall plate 13 is used as a constraint on the stepper motor stroke, controlling the total vertical amplitude to avoid exceeding the mechanical range. The general approach is that the rack 42 has a built-in magnet 48, and the Hall plate 13 has a magnetic induction element. The magnet 48 rotates counterclockwise with the rack 42 to reach the induction element, then turns back and rotates clockwise to reach the induction element again, thus obtaining a reference measurement of the position. The number of steps taken within the measurement range is divided into 256 parts, or 256*256 pulse segments, to obtain the effective single step to be taken. Finally, based on the data sent by the DMX control system, the control circuit board 12 calculates and commands the stepper motor to rotate the corresponding amplitude.

[0065] To further optimize the above technical solution, a handle bracket 14 is externally rotatably connected to the chassis body 1. The connection between the handle bracket 14 and the chassis body 1 is provided with a through hole 141 and an arc-shaped hole 142, with the centers of the through hole 141 and the arc-shaped hole 142 at the same position. Screws 144 are installed in both the through hole 141 and the arc-shaped hole 142, and the screws 144 are connected to the chassis body 1. A cup-head screw is installed at the through hole 141 as an intermediate rotating shaft, typically adjusted using an Allen wrench. A friction plate 143 is provided at the connection between the cup-head screw and the chassis body 1 to increase friction and lock the cup-head screw. A rubber-head screw is installed at the arc-shaped hole 142 to increase friction and lock the rubber-head screw. The friction plate 143 at the connection between the rubber-head screw and the chassis body 1 is used for adjusting the direction and fixing, providing a precise aiming direction.

[0066] To further optimize the above technical solution, a copper wire clip 15 is provided on the outside of the main body 1 of the chassis. The copper wire clip 15 secures the cable, which is connected to the control circuit board 12. The copper wire clip 15 is used to lock the cable, and the cable sheath bears the force, preventing external pulling from causing stress on the internal solder joints.

[0067] The path change process of light reflection is as follows:

[0068] like Figure 8As shown, a micro-element is taken on the entire freeform surface of reflection. Referring to the local plane XOY, an inclined incident ray AO is simulated, where O is a point on the plane; OZ is its normal, resulting in the reflected ray BO. The movement direction of the horizontal moving component 5 can be understood as moving along the positive axis on the OY axis. At the same time, after the vertical moving component 4 rotates, the landing point of the same ray AO at this micro-element becomes C, where point C is a point outside the original XOY plane with a three-dimensional drop, generating a new normal FC and a new reflected ray EC. Correspondingly, the plane determined by the three points ACE is now a completely different plane from the plane determined by the three points AOB. The BO ray quickly becomes the EC ray. The two rays are on different planes and also produce a three-dimensional angle. The landing point of the ray on the illuminated surface will also produce a large displacement, causing the actual light spot to change significantly in a short period of time.
