Description

Technical Field

[0001] This utility model relates to the field of soft light technology, and in particular to a six-color digital soft light. Background Technology

[0002] The six-color digital soft light is a high-end product of modern film and television lighting technology. It utilizes multi-primary-color LED light sources and achieves ultra-wide color gamut and precise color adjustment through a digital control system. With the help of an optimized soft light structure, it outputs extremely uniform, soft, and non-aggressive high-quality light. It is widely used in professional photography studios, broadcasting studios, high-end live broadcasts, film and television production and other fields that require precise light and shadow control and excellent picture quality.

[0003] Existing six-color digital soft lights typically have a relatively simple driving method for functions such as focusing and dimming. The manual adjustment method has obvious limitations and makes it difficult to achieve precise and repeatable adjustments, especially in film and television shooting or stage lighting applications that require fine control over the position and focal length of the light spot. Furthermore, motor-driven adjustment consumes electricity, and if the motor fails, the equipment will be unusable, resulting in poor reliability. Therefore, using only one driving method has significant limitations. Utility Model Content

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] like Figures 1 to 8 As shown, this utility model discloses a six-color digital soft light, comprising a housing 1 and a light source assembly 2 disposed inside the housing 1. The light source assembly 2 includes a light source fixing plate 21 installed inside the housing 1, on which a light-emitting element 22 is mounted. The light-emitting element 22 is a high-brightness LED chip unit of six colors. To improve the light output quality, an aspherical lens 23 is provided at the light output end of the light-emitting element 22. The aspherical lens 23 is used to initially shape and focus the emitted light, thereby improving the concentration of the light spot. A light-transmitting plate 3 is provided in front of the light source assembly 2. The light-transmitting plate 3 is preferably made of waterproof tempered glass, which has excellent light transmittance, high temperature resistance and impact resistance, and can effectively protect the internal structure from the influence of external dust, moisture and collision. An adjustable threaded lens group 4 is provided between the light-transmitting plate 3 and the aspherical lens 23. The threaded lens group 4 is used to further adjust the divergence angle and projection focal length of the light beam, including a threaded lens 41, a lens bracket 42 for supporting the movement of the threaded lens 41, and a transmission mechanism 43 for driving the movement of the lens.

[0031] The lens holder includes a first limiting plate 421, a second limiting plate 422, and a guide rod disposed therebetween. A threaded lens fixing plate 45 is slidably mounted on the guide rod 44, and the threaded lens 41 is fixedly mounted on the threaded lens fixing plate 45. Driven by the transmission mechanism 43, the threaded lens fixing plate 45 can move back and forth along the axial direction of the guide rod 44, thereby realizing the adjustment of the focal position of the lens group and achieving various light effect control functions such as focusing and variable angle illumination. The first limiting plate 421 and the second limiting plate 422 limit the movement range of the threaded lens 41 to prevent excessive movement from damaging the transmission mechanism.

[0032] One end of the transmission mechanism 43 is connected to a drive motor 431, and the other end is equipped with a drive knob 432. The user can make electric control adjustments through the drive motor 431, or make manual adjustments through the drive knob 432 when there is no power. The transmission mechanism 43 includes a transmission bracket 433, a first wheel axle 434 and a second wheel axle 435. The first wheel axle 434 and the second wheel axle 435 are connected by a closed transmission belt 436 to form a closed loop. The threaded lens fixing plate 45 is connected to the transmission belt 436. When the first wheel axle 434 and the second wheel axle 435 rotate, the transmission belt 436 drives the threaded lens fixing plate 45 to move synchronously, thereby driving the threaded lens 41 to move back and forth.

[0033] A driven gear 437 is connected to the first axle 434, and a driving gear 438 meshes with the driven gear 437. A first transmission rod 4311 is connected to the drive motor 431, and a second transmission rod 4321 is connected to the drive knob 432. The drive knob 432 can move axially along the first transmission rod 4311 and the second transmission rod 4321. One end of the second transmission rod 4321 abuts against the first transmission rod 4311, and a ball bearing is provided between the second transmission rod 4321 and the first transmission rod 4311. The ball bearing reduces the friction between the second transmission rod 4321 and the first transmission rod 4311, allowing the second transmission rod 4321 to drive the first transmission rod 4311 axially without rotating synchronously. The first transmission rod 4311 and the second transmission rod 4321 pass through the drive gear 438. The first transmission rod 4311 is provided with a first splined shaft 4312, and the drive gear 438 is provided with a first spline groove 4381 on the side near the first splined shaft 4312. The first splined shaft 4312 and the first spline groove 4381... 1. Plug-in fit; The second transmission rod 4321 is provided with a second splined shaft 4322, and the drive gear 438 is provided with a second splined groove 4382 on the side near the second splined shaft 4322. In the initial state, when the first splined shaft 4312 is inserted into the first splined groove 4381, the drive motor 431 can drive the drive gear 438 to rotate. The user first presses the drive knob 432 to make the first splined shaft 4312 leave the first splined groove 4381, and at the same time, the second splined shaft 4322 inserts into the second splined groove 4382. Rotating the drive knob 432 will drive the drive gear 438 to rotate. With this structure, the distance of the threaded lens 41 can be adjusted in both automatic and manual control modes. A limit wheel shaft 46 is provided between the drive gear 438 and the knob. The limit wheel shaft 46 is provided with multiple limit holes 461. The housing 1 is provided with a limit rod 47. The user can insert the limit rod 47 into the limit holes 461 at different positions as needed to lock the transmission mechanism 43 and prevent the threaded lens 41 from shifting during use.

[0034] The housing 1 contains a motor bracket 11, on which a movable plate 111 is slidably mounted. A drive motor 431 is fixed to the movable plate 111. One end of the motor bracket 11 has a support plate 112, and an elastic element 439 is provided between the support plate 112 and the movable plate. When the user presses the drive knob 432, the drive knob 432 and the second transmission rod 4321 move inward. Since the first transmission rod 4311 abuts against the second transmission rod 4321, the first transmission rod 4311 drives the movable plate to move towards the support plate 112, causing the first spline shaft 4312 to leave the first spline groove 4381, while the second spline shaft 4322 inserts into the second spline groove 4382. At the same time, the elastic element 439 is compressed. When the user releases the drive knob 432, the elastic element 439 causes it to reset, allowing the first spline shaft 4312 to return to the first spline groove 4381.

[0035] A heat dissipation assembly 5 is provided at the rear end of the housing 1. The heat dissipation assembly 5 includes a heat-conducting plate 51 that is closely attached to the back of the light source fixing plate 21. It is used to quickly conduct the heat generated by the light-emitting element 22 to the heat exchange section. Multiple heat dissipation pipes 52 are welded on the heat-conducting plate 51. Several heat dissipation fins 53 are distributed on each heat dissipation pipe 52 to significantly increase the heat exchange area and improve the natural convection efficiency. A rear end cover 54 is provided at the rear end of the heat dissipation assembly 5. A fan 55 is installed inside the rear end cover 54. The fan 55 is used to continuously blow air into the area of ​​the heat dissipation pipes 52 to accelerate air circulation and thus significantly improve the heat dissipation efficiency.

[0036] The operation of fan 55 is controlled by control circuit board 56 located inside rear cover 54. The start and stop of fan 55 can be adjusted according to user needs. When fan 55 is on, it can improve heat dissipation efficiency. When fan 55 is off, it can dissipate heat through natural convection and reduce noise. The two heat dissipation methods provide users with more choices.

[0037] A power supply bracket 6 is provided below the heat dissipation component 5. A power supply module 61 is installed inside the power supply bracket 6 to provide stable voltage and current to components such as the light source component 2, fan 55 and control board. A dimming board 62 is provided on one side of the power supply module 61. The dimming board 62 communicates with the main control chip to achieve fine adjustment of the brightness of each channel of the six-color LED, meeting the dimming control needs of various usage environments such as photography studios, broadcasting studios, and stages.

[0038] The front end of the housing 1 is also provided with a front cover 7 and a mounting plate 71. The light-transmitting plate 3 is sandwiched between the front cover 7 and the mounting plate 71. In order to improve the sealing performance, a sealing ring 72 is provided between the mounting plate 71 and the light-transmitting plate 3. The sealing ring 72 can effectively prevent external moisture and dust from entering the interior of the housing 1, ensuring that the whole lamp reaches a high protection level and is suitable for outdoor humid working environments.

[0039] The basic working principle of this utility model is as follows: The power module 61 inside the soft light starts to supply power to the light source assembly 2. After receiving the control signal, the light-emitting element 22 lights up accordingly. After the light is emitted from the light-emitting element 22, it first passes through the aspherical lens 23 set in front of it for preliminary shaping and focusing. Then, the light beam enters the area of ​​the threaded lens group 4 located between the aspherical lens 23 and the light-transmitting plate 3. If the user needs to adjust the focus, the control system can control the drive motor 431 to operate, and the drive transmission mechanism 43 drives the threaded lens 41 to move back and forth, thereby adjusting the convergence and divergence of the light beam. At the same time, the user can also manually adjust it using the drive knob 432. First, press the drive knob... The knob 432 can be manually adjusted by rotating the drive knob 432. The limit rod 47 can be inserted into the limit hole 461 on the limit wheel shaft 46 to lock the transmission mechanism 43. The adjusted beam of light is finally output through the light-transmitting plate 3 installed at the front end of the housing 1. During the operation of the light source, in order to prevent the temperature from being too high and affecting the stability and life of the light source, the heat dissipation component 5 operates synchronously. The heat conduction plate 51 quickly absorbs the heat generated by the light-emitting element 22 and evenly transfers the heat to the area where the heat dissipation fins 53 are distributed through the connected heat dissipation pipe 52. If it is necessary to further improve the heat dissipation efficiency, the fan 55 installed at the rear end of the housing 1 can be started to work and send air to the heat dissipation component 5.

[0040] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
