Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a golden yellow powder-free light source system for exhibition purposes. Background Technology

[0002] In the field of exhibition, the quality of light source directly affects the presentation effect and lifespan of exhibits. Traditional exhibition light sources have many shortcomings: First, most of them use phosphors to achieve specific light colors. Phosphors will age and decay over time, resulting in unstable light colors and limited lifespan. The phosphors will gradually age during long-term use, resulting in significant light decay and unstable spectral characteristics, making it difficult to accurately and continuously provide the lighting effect required for exhibitions. The golden yellow powder-free light source system is used for exhibition lighting, illuminating the exhibits so that people can clearly see them.

[0003] Existing golden yellow powder-free light source systems typically control the brightness of the LED beads by adjusting the current. However, the current adjustment process is not precise, making it impossible to finely adjust the brightness and adapt to various exhibition environments. Therefore, there is a need for a dedicated golden yellow powder-free light source system for exhibitions. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where the brightness of the light from the LED is controlled by the magnitude of the current, which is not precise during the current adjustment process, cannot finely adjust the brightness of the light, and cannot adapt to various exhibition environments. Therefore, this invention proposes a special golden yellow powder-free light source system for exhibitions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a special golden light powder-free light source system for exhibitions, comprising a mounting plate and a mounting box mounted at its bottom. Multiple LED beads are mounted on the top of the mounting plate. A threaded cylinder and a reflector cylinder are mounted on the top of the mounting plate. A lower lens is nested and fixed at one end of the reflector cylinder. A middle cylinder is threadedly connected to one end of the threaded cylinder. A hexagonal ring is nested and fixed in the middle of the middle cylinder. A middle lens is fixedly disposed on the inner side of the middle cylinder. A reverse cylinder is threadedly connected to one end of the middle cylinder. A transparent sheet is fixedly mounted at one end of the reverse cylinder. A fixing ring is fixedly mounted at the bottom of the transparent sheet. An upper lens is nested and fixed at one end of the fixing ring. Multiple upper transparent sheets are fixed to the side of the reverse cylinder. Multiple lower transparent sheets are fixed to the side of the threaded cylinder. Movable bolts pass through the lower and upper transparent sheets, and a threaded ring is threadedly connected to one end of the movable bolt.

[0006] More preferably, one end of the movable bolt is integrally formed with a cylindrical block, and a threaded ring is threadedly sleeved on the other end of the movable bolt, with the position of the threaded ring being symmetrical to the position of the cylindrical block.

[0007] More preferably, the light transmittance of the middle lens, lower lens, and upper lens is 89%-91%, and the middle lens is located between the lower lens and the upper lens.

[0008] More preferably, the lens is concave, the lower lens is convex, the upper lens is convex, and the middle lens, lower lens, and upper lens together form a convex lens.

[0009] More preferably, the inner sides of the reflector and the fixing ring are provided with a reflective coating, the diameters of the reflector and the fixing ring are consistent, and the shapes of the lower lens and the upper lens are consistent.

[0010] More preferably, both ends of the intermediate cylinder are provided with external threads, the external threads at both ends of the intermediate cylinder have opposite helical directions, and one end of the threaded cylinder and the reverse cylinder are both provided with internal threads.

[0011] More preferably, the lamp beads are a combination of yellow lamp beads with a peak wavelength in the 560nm-570nm band and red chips with a peak wavelength in the 620nm-635nm band. Two types of chips are installed on the mounting plate. By precisely controlling the current ratio and layout of the two types of chips, the lamp beads can accurately output golden light that can highlight the brilliant texture and color of gold jewelry.

[0012] The beneficial effects of this utility model are as follows: the lower lens, middle lens, and upper lens form a convex lens. The lower lens and upper lens are on both sides, and the middle lens moves in opposite directions. This allows adjustment of the thickness of the convex lens formed by the lower lens, middle lens, and upper lens, which can change the light-gathering power of the convex lens, thereby changing the intensity of the light illuminating the exhibited items. By adjusting the distance between the lower lens and the middle lens through the thread, the thickness of the convex lens can be precisely adjusted, and the light brightness can be finely adjusted. This allows it to adapt to various exhibition environments. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1 to 3 A special golden light powder-free light source system for exhibitions includes a mounting plate 1 and a mounting box 2 installed at its bottom. Multiple LED beads 3 are installed on the top of the mounting plate 1. A threaded cylinder 4 and a reflector 5 are installed on the top of the mounting plate 1. A lower lens 6 is nested and fixed at one end of the reflector 5. A middle cylinder 7 is threadedly connected to one end of the threaded cylinder 4. A hexagonal ring 9 is nested and fixed in the middle of the middle cylinder 7. A middle lens 8 is fixedly installed on the inner side of the middle cylinder 7. A reverse cylinder 10 is threadedly connected to one end of the middle cylinder 7. A transparent sheet 17 is fixedly installed at one end of the reverse cylinder 10. A fixing ring 11 is fixedly installed at the bottom of the transparent sheet 17. An upper lens 12 is nested and fixed at one end of the fixing ring 11. Multiple upper transparent sheets 13 are fixed to the side of the reverse cylinder 10. Multiple lower transparent sheets 16 are fixed to the side of the threaded cylinder 4. A movable bolt 14 passes through the lower transparent sheets 16 and the upper transparent sheets 13. A threaded ring 15 is threadedly connected to one end of the movable bolt 14.

[0019] Preferably, one end of the movable bolt 14 is integrally formed with a cylindrical block, and the threaded ring 15 is threadedly sleeved on the other end of the movable bolt 14. The position of the threaded ring 15 is symmetrical with the position of the cylindrical block. The threaded ring 15 abuts against the lower through plate 16, and the movable bolt 14 abuts against the upper through plate 13. The movable bolt 14 and the threaded ring 15 limit the distance between the threaded cylinder 4 and the reverse cylinder 10.

[0020] Preferably, the light transmittance of the transparent sheet 17, the middle lens 8, the lower lens 6 and the upper lens 12 is 89%-91%. The middle lens 8 is located between the lower lens 6 and the upper lens 12. The lens 8 is concave, the lower lens 6 is convex, and the upper lens 12 is convex. The middle lens 8, the lower lens 6 and the upper lens 12 form a convex lens.

[0021] In practice, the lower lens 6, the middle lens 8, and the upper lens 12 form a convex lens. The middle lens 8 moves in opposite directions on both sides of the lower lens 6 and the upper lens 12, which can adjust the thickness of the convex lens formed by the lower lens 6, the middle lens 8, and the upper lens 12. This can change the light-gathering power of the convex lens, thereby changing the intensity of the light shining on the exhibited items. The distance between the lower lens 6 and the middle lens 8 can be adjusted by the screw thread.

[0022] Preferably, the inner sides of the reflector 5 and the fixing ring 11 are provided with a reflective coating, the diameters of the reflector 5 and the fixing ring 11 are the same, the lower lens 6 and the upper lens 12 have the same shape, and the reflective coating on the inner side of the reflector 5 and the fixing ring 11 can reflect light and increase the brightness from the side.

[0023] Preferably, both ends of the intermediate cylinder 7 are provided with external threads, and the external threads at both ends of the intermediate cylinder 7 have opposite helical directions. The inner side of one end of the threaded cylinder 4 and the reverse cylinder 10 are both provided with internal threads. The intermediate cylinder 7 rotates between the threaded cylinder 4 and the reverse cylinder 10, so that the threaded cylinder 4 and the reverse cylinder 10 move in opposite directions. The threaded cylinder 4 and the reverse cylinder 10 can move away from each other or move closer to each other, so that the lower lens 6 and the upper lens 12 move away from each other or move closer to each other than the middle lens 8, ensuring that the distance between the lower lens 6 and the upper lens 12 and the middle lens 8 is consistent.

[0024] Preferably, the LED bead 3 is a combination of a yellow LED bead with a peak wavelength in the 560nm-570nm band and a red chip with a peak wavelength in the 620nm-635nm band. The mounting plate 1 is equipped with two types of chips. The LED bead 3 accurately outputs golden light that can highlight the brilliant texture and color of gold jewelry by precisely controlling the current ratio and layout of the two types of chips.

[0025] In practical implementation, the LED beads 3 adopt specifications such as 3535 and 5050, which facilitates high-density layout within the limited space of the display lighting fixture. High thermal conductivity and high light transmittance encapsulation materials (such as new organic silicone resin) are used to ensure effective heat dissipation of the chip and minimize light loss in the encapsulation layer, so that the light can be emitted efficiently. The encapsulation structure is designed with a special reflective layer and scattering structure to optimize the light emitted by the chip, guide the light to propagate in a predetermined direction and mix it evenly, improve the integration and light emission uniformity of the light source, and ensure that all parts of the gold jewelry can be evenly illuminated, showcasing its exquisite craftsmanship and unique luster.

[0026] Among them, mounting plate 1, mounting box 2, and LED beads 3 can be obtained by purchasing from the market or by private customization.

[0027] In this invention, during use, firstly, the mounting plate 1 is installed around the display items. Secondly, the mounting box 2 has an internal circuit that powers the LED beads 3 on the mounting plate 1. The light emitted by the LED beads 3 passes through the lower lens 6, the middle lens 8, and the upper lens 12. The light is focused by the convex lens formed by the lower lens 6, the middle lens 8, and the upper lens 12, causing the focused light to illuminate the display items. Next, the hexagonal ring 9 is rotated, causing the hexagonal ring 9 and the intermediate cylinder 7 to rotate. The movable bolt 14 passes through the upper transparent plate 13 and the lower transparent plate 16. The upper transparent plate 13 and the lower transparent plate 16 are respectively fixed to the sides of the reverse cylinder 10 and the threaded cylinder 4, preventing the threaded cylinder 4 and the reverse cylinder 10 from rotating synchronously with the intermediate cylinder 7. As the external threads at both ends of the intermediate cylinder 7 move in opposite directions, the threaded cylinder 4 and the reverse cylinder 10 move away from each other at both ends of the intermediate cylinder 7. The intermediate cylinder 7, the transparent sheet 17, the upper transparent sheet 13, the fixing ring 11, and the upper lens 12 move upward synchronously. The intermediate cylinder 7, the middle lens 8, and the hexagonal ring 9 move upward at the top of the threaded cylinder 4. The threaded cylinder 4 and the reverse cylinder 10 move away from each other relative to the intermediate cylinder 7. The lower lens 6 and the upper lens 12 move away from the middle lens 8 synchronously. The thickness of the convex lens composed of the middle lens 8, the lower lens 6, and the upper lens 12 increases. The convex lens focuses the light emitted by the lamp bead 3, converging the light onto the exhibited items to ensure that people can clearly observe the exhibited items.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
