Description

Technical Field

[0001] This utility model relates to the field of imaging lamp technology, and in particular to a seven-color high-resolution imaging lamp. Background Technology

[0002] As an important light source for stage lighting, film and television shooting, and professional performances, the clarity, color rendering performance, and structural stability of imaging lights directly affect image quality. To meet the needs of different application scenarios, existing imaging lights are constantly being optimized in terms of optical systems, heat dissipation systems, and control systems, and the type of light source is gradually being upgraded from traditional halogen lamps to multi-color light sources such as LEDs.

[0003] Existing imaging lights generally suffer from technical problems such as inconvenient disassembly and assembly, and unstable structure. This is particularly evident in the connection method between the lens assembly and the camera body. Specifically, existing imaging lights mostly use threaded connections or screw fixation to install the lens assembly onto the camera body. This requires the use of tools for installation and disassembly, making it inconvenient to quickly replace the lens assembly. It is also prone to problems such as lens loosening and misalignment, which can lead to optical path deviation or image blurring, affecting the performance. Utility Model Content

[0004] The purpose of this invention is to provide a seven-color high-resolution imaging lamp, in which the lens assembly can be quickly assembled with the camera body, and the lens assembly will not loosen due to vibration during use, thereby improving the reliability of the overall structure.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a seven-color high-resolution imaging lamp, comprising a body, a light source assembly disposed within the body, and a lens assembly mounted on the body. The light source assembly includes a light source fixing plate and a light-emitting element disposed on the light source fixing plate, with an aspherical lens at the front end of the light-emitting element. The lens assembly includes a lens housing, a connector, and a lens assembly sequentially mounted within the lens housing. The lens housing and the body are detachably connected via the connector. The connector is provided with a first limiting ring and a second limiting ring, with a limiting groove formed between the first and second limiting rings. The first and second limiting rings are connected by a limiting block. The body is provided with a locking mechanism for locking the limiting block. By adopting the above technical solution, the lens assembly and the body can be quickly assembled, and the installed lens assembly will not loosen due to vibration during use, thus improving the overall structural reliability.

[0006] A further feature of this invention is that the locking mechanism includes a locking tongue, a movable plate connected to the locking tongue, and an annular connector connected to the movable plate. The locking tongue passes through the limiting groove. A fixing block is also provided on the inner wall of the body. The limiting block can be engaged between the locking tongue and the fixing block. The second limiting stop ring is provided with an avoidance groove that allows the locking tongue to pass through. A locking knob is provided on the body. A locking rod is provided on the locking knob. The locking rod is threadedly connected to the annular connector. By adopting the above technical solution, the locking mechanism can drive the locking rod by rotating the locking knob, thereby linking the movable plate and the locking tongue, to achieve rapid locking and releasing of the limiting block, thus improving the efficiency of lens assembly assembly and disassembly.

[0007] A further feature of this invention is that the latch is provided with a guide slope. By adopting the above technical solution, when the limiting block moves to the guide slope of the latch, the limiting block will slide along the guide slope to drive the latch to move downward, so that the limiting block can pass smoothly through the latch. However, the other end of the latch does not have a guide slope, so the limiting block cannot go back to the front of the latch.

[0008] A further feature of this invention is that the body is provided with a guide groove, the annular connector is provided with a guide protrusion, and the guide protrusion is slidably disposed in the guide groove. By adopting the above technical solution, the annular connector drives the locking tongue to move up and down along the guide groove to control the locking and releasing of the limit block.

[0009] A further feature of this invention is that a fixing ring is provided inside the body, and an elastic element is provided between the fixing ring and the movable plate. By adopting the above technical solution, the limiting block passes through the locking tongue, and the locking tongue quickly rebounds, so that the limiting block is quickly locked on one side of the locking tongue.

[0010] A further feature of this invention is that the locking rod has a protruding post, and the annular connector has a spiral groove. The protruding post is slidably connected in the groove. By adopting the above technical solution, the rotational motion can be converted into vertical axial motion by the protruding post sliding along the spiral groove, thereby controlling the advance and retreat of the locking tongue.

[0011] A further feature of this invention is that the lens assembly includes an outer lens, a first lens, a second lens, a third lens, and an inner lens. The outer lens is disposed at the end of the lens housing away from the camera body, and the inner lens is disposed at the end of the lens housing close to the camera body. The first lens, the second lens, and the third lens are arranged sequentially between the outer lens and the inner lens. By adopting the above technical solution, the light beam is corrected and focused by multiple sets of lenses, which can effectively reduce imaging distortion and chromatic aberration, and improve imaging quality and color rendering performance.

[0012] A further feature of this invention is that a translucent tempered glass is provided between the connector and the body, and a waterproof sealing ring is provided between the translucent tempered glass and the body. By adopting the above technical solution, the sealing and protection capabilities of the lens connection part are enhanced, preventing dust and water mist from intruding and improving the durability of the imaging lamp in humid environments.

[0013] A further feature of this invention is that the front end of the translucent tempered glass is provided with a light shutter assembly, which includes multiple light-shielding plates and an adjustment rod disposed on the light-shielding plates. By adopting the above technical solution, the light shutter assembly can cut or shape the edge of the emitted light beam as needed, making the imaging area more regular and meeting the styling requirements of professional applications such as theatrical lighting effects and pattern projection.

[0014] A further feature of this invention is that an aspherical mirror is provided at the front end of the light-emitting element. By adopting the above technical solution, the aspherical mirror can optimize beam shaping, reduce spherical aberration, improve focusing efficiency and uniformity of emitted light, thereby enhancing the imaging clarity and long-distance projection capability of the lamp.

[0015] A further feature of this invention is that a heat dissipation assembly is provided at the rear end of the body. The heat dissipation assembly includes a heat-conducting plate, a heat pipe, and heat dissipation fins. The heat-conducting plate is located behind the light source fixing plate. The heat dissipation fins are connected to the heat-conducting plate through the heat pipe. A heat dissipation fan is also provided behind the heat dissipation fins. By adopting the above technical solution, heat is efficiently conducted to the fins through the heat pipe, and the heat is quickly carried away by the heat dissipation fan, thereby achieving efficient heat dissipation and ensuring the stable operating temperature of the light-emitting element.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. The lens assembly of this utility model can be quickly assembled with the camera body, and the lens assembly will not loosen due to vibration during use after installation, thus improving the reliability of the overall structure.

[0031] The present invention will be further described below with reference to the accompanying drawings.

[0032] like Figures 1 to 8As shown, this utility model discloses a seven-color high color rendering imaging lamp, comprising a body 1, a light source assembly 2 disposed inside the body 1, and a lens assembly 3 mounted at the front end of the body 1. The light source assembly 2 includes a light source fixing plate 21, which is fixedly mounted inside the body 1. A light-emitting element 22 is mounted on the light source assembly 21, which is a high color rendering LED chip capable of emitting seven different wavelengths of light, namely red, green, blue, cyan, yellow, purple, and white, to meet the requirements of multispectral imaging or high color rendering. An aspherical mirror 7 is also provided at the front end of the light-emitting element 22 for shaping and collimating the light beam, thereby improving image clarity and optical efficiency.

[0033] The lens assembly 3 includes a lens housing 31, a connector 32, and a lens assembly 33 installed sequentially inside the lens housing 31. The lens assembly 33 includes an outer lens 331, a first lens 332, a second lens 333, a third lens 334, and an inner lens 335. The outer lens 331 is located at the end of the lens housing 31 away from the camera body 1, and the inner lens 335 is located at the end of the lens housing 31 closer to the camera body 1. The remaining first lens 332, second lens 333, and third lens 334 are arranged sequentially between the outer lens 331 and the inner lens 335. Through multi-layer combination, optical functions such as imaging focal length adjustment and chromatic aberration correction are realized, ensuring that the output image has high sharpness and true color reproduction capability.

[0034] The connector 32 is installed on the end of the lens housing 31 near the body 1, and is detachably connected to the body 1. To achieve quick installation, the connector 32 is provided with a first limiting ring 321 and a second limiting ring 322, which together form a limiting groove 323. The first limiting ring 321 and the second limiting ring 322 are connected by a limiting block. The body 1 is provided with a locking mechanism 12 to restrict the movement of the limiting block 325 within the limiting groove 323. The locking mechanism 12 includes a locking tongue 121, a movable plate 122, and an annular connector 123. The movable plate 122 is connected to one end of the locking tongue 121, and the other end is connected to the annular connector 123. The connecting piece 123 has a locking tongue 121 inserted into the limiting groove 323, which has a guide slope 1211. When the limiting block 325 contacts the guide slope 1211, it can drive the locking tongue 121 to move downward, allowing the limiting block 325 to pass smoothly and not back. The inner wall of the body 1 is also provided with a fixing block 11. After the limiting block passes the locking tongue, the fixing block 11 will prevent the limiting block from moving further, so that the limiting block is locked between the locking tongue and the fixing block 11 to prevent it from falling off. In order to facilitate the smooth insertion of the locking tongue 121 into the limiting groove 323, the second limiting retaining ring 322 is provided with an avoidance groove 324 to make the assembly process smooth.

[0035] The camera body 1 is equipped with a locking knob 13 on the outside. The locking knob 13 is equipped with a locking rod 131, which is threaded onto the annular connector 123. By rotating the locking knob 13, the locking rod 131 can be driven to drive the annular connector 123 and the movable plate 122, so that the locking tongue 121 can move up and down, thereby locking or releasing the limit block 325, thus completing the quick assembly and disassembly of the lens assembly 3.

[0036] The body 1 is provided with a guide groove 14, and the annular connector 123 is provided with a guide protrusion 1231. The guide protrusion 1231 is slidably disposed in the guide groove 14 to control the annular connector 123 to move up and down along the guide groove 14. The body 1 is also provided with a fixing ring 15. An elastic element 16, such as a compression spring, is provided between the fixing ring 15 and the movable plate 122. After the limiting block 325 passes through the locking tongue 121, the locking tongue 121 is quickly rebounded to limit the movement of the limiting block 325.

[0037] The locking rod 131 is provided with a protrusion 132, and the annular connector 123 is provided with a spirally arranged groove 1232. The protrusion 132 is slidably disposed in the groove 1232. When the knob is rotated, the protrusion 132 moves along the spiral path in the groove 1232, converting the rotational motion into axial motion in the vertical direction, thereby controlling the advance and retreat of the locking tongue 121.

[0038] A translucent tempered glass 4 is provided between the connector 32 and the body 1. This glass is used to isolate the influence of external dust and moisture on the internal optical components. A waterproof sealing ring 5 is provided between the translucent tempered glass 4 and the body 1 to improve the overall protection level and is suitable for outdoor high humidity environments.

[0039] The front end of the translucent tempered glass 4 is provided with a light shutter assembly 6. The light shutter assembly 6 includes multiple light shields 61 and an adjustment rod 62 on the light shields 61. Users can adjust the opening and closing state of the light shields 61 by adjusting the adjustment rod 62, thereby controlling the light output angle, the occlusion range, or achieving effects such as pattern edge control. It is suitable for stage, film and television shooting, or image processing scenarios.

[0040] To ensure system stability during long-term continuous operation, a heat dissipation assembly 8 is provided at the rear of the housing 1. The heat dissipation assembly 8 includes a heat-conducting plate 81, heat pipes 82, and heat dissipation fins 83. The heat-conducting plate 81 is attached to the back of the light source fixing plate 21 to absorb the heat generated by the light-emitting element 22 in a timely manner. Multiple heat pipes 82 rapidly conduct heat and distribute it to multiple heat dissipation fins 83. A cooling fan is also provided behind the heat dissipation fins 83 to accelerate airflow, achieving efficient active heat dissipation and preventing overheating of the components from affecting performance or lifespan.

[0041] The basic working principle of this utility model is as follows: During assembly, when the connector 32 is inserted into the body 1, the locking tongue 121 is inserted into the limiting groove 323 through the clearance groove 324 on the second limiting ring 322. Then, the connector 32 is rotated, causing the limiting block 325 to move to the locking tongue 121. When the limiting block 325 contacts the guide inclined surface 1211, it can drive the locking tongue 121 to move downward, allowing the limiting block 325 to pass smoothly. After the limiting block 325 passes the locking tongue 121... The elastic element 16 causes the locking tongue 121 to rebound quickly, thereby limiting the movement of the limiting block 325 and locking the limiting block 325 between the locking tongue 121 and the fixing block 11. After the lamp is powered on, the light-emitting element 22 in the light source assembly 2 lights up, producing a high color rendering, multi-spectral light beam. These light beams are shaped by the aspherical mirror 7 set at the front end, further optimizing the beam angle and light uniformity. The emitted light passes through the light-transmitting tempered glass 4 at the front end of the body 1 and enters the lens assembly 3. The lens assembly 3 is composed of an outer lens 331, a first lens 332, a second lens 333, a third lens 334, and an inner lens 335 in sequence, forming a complete optical imaging system. These lenses work together to focus, shape, and filter light, ultimately projecting a clear, high-color-rendering imaging spot. When disassembling, the user turns the locking knob 13 on the body 1, causing the annular connector 123 to push the locking tongue 121 to move, thereby disengaging the locking tongue 121 from the limiting block 325. The connector 32 can then be rotated to easily disassemble the device.

[0042] 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.
