[0002] Golden-yellow powder-free light sources and luminaire structures specifically designed for exhibitions are widely used in museums, exhibition halls, galleries, and other exhibition and display venues. Their blue-light-free and high color rendering index characteristics accurately reproduce the colors and details of exhibits, providing visitors with a better viewing experience. Furthermore, the phosphor-free design aligns with environmental protection and sustainable development principles. Currently, most golden-yellow powder-free light sources and luminaire structures for exhibitions are installed and fixed within display cases using multiple threaded bolts. However, this method only works for luminaires of the same size. When changing to different sizes, different display cases are required, increasing the cost of using the display cases and making installation and maintenance inconvenient. Therefore, a dedicated golden-yellow powder-free light source and luminaire structure for exhibitions is needed to solve these problems. Utility Model Content

[0003] The purpose of this invention is to solve the problems of inconvenience in installing and maintaining lamps of different sizes in the existing technology, and to propose a special golden yellow powder-free light source and lamp structure for exhibitions.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a golden yellow powder-free light source and lamp structure for exhibition purposes, comprising a base plate, several legs fixedly installed at the bottom of the base plate, several uprights fixedly installed at the top of the base plate, a glass plate horizontally fixedly installed at the top of the uprights, and a transparent plate fixedly installed between each pair of uprights, a cover plate movably installed at both ends of the top of the glass plate, and a lamp tube movably installed at both the front and rear ends of the bottom of the glass plate, with the lamp tube located at the top inner end of the transparent plate, and the interior of the lamp tube integrating a golden yellow powder-free light source module, wherein an installation mechanism is fixedly installed inside the uprights at the center of both the front and rear ends, and the lamp tube is fixedly installed inside the display case through the installation mechanism.

[0005] Furthermore, the installation mechanism includes a groove vertically formed inside the upright, a threaded rod vertically rotatably mounted inside the groove, a turntable fixedly mounted at the bottom end of the threaded rod and located below the base plate, and a threaded block threaded on the surface of the threaded rod and located inside the groove.

[0006] Furthermore, rectangular sliding rods are fixedly installed laterally at both ends of the threaded block, and rectangular rod grooves are vertically opened at both ends of the upright rod, with the rectangular rod grooves communicating with the grooves, and the rectangular sliding rods are slidably installed in the rectangular rod grooves.

[0007] Furthermore, several rectangular sliding plates are slidably arranged on the surface of the rectangular slide bar, and an L-shaped plate is fixedly arranged at the inner end of each of the rectangular sliding plates. A screw is rotatably arranged at the center of the inner end of each of the L-shaped plates, and the screw is located above the rectangular sliding plate.

[0008] Furthermore, a bearing is threaded on the inner end of the screw, and a clamp is fixedly installed on the inner end of the bearing. The clamp is located on the rectangular slide plate, and the inner end of the clamp is in contact with the lamp tube. A handle is fixedly installed on the outer end of the screw, and the handle is located outside the L-shaped plate.

[0009] Furthermore, the internal light of the lamp tube is a powder-free light source spectrum composed of yellow LED chips with peak wavelengths in the 550-570nm band and red LED chips with peak wavelengths in the 610-630nm band.

[0010] The beneficial effects of this utility model are as follows: 1.

[0018] 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.

[0019] Reference Figures 1 to 6 This embodiment provides a special golden yellow powder-free light source and lamp structure for exhibitions, including a base plate 1, several legs 2 fixedly installed at the bottom of the base plate 1, several uprights 3 fixedly installed at the top of the base plate 1, a glass plate 4 horizontally fixedly installed at the top of the uprights 3, and a transparent plate 5 fixedly installed between each pair of uprights 3. Cover plates 6 are movably installed at both ends of the top of the glass plate 4, and lamp tubes 7 are movably installed at both the front and rear ends of the bottom of the glass plate 4. The lamp tubes 7 are located at the top inner end of the transparent plate 5, and a golden yellow powder-free light source module is integrated inside the lamp tubes 7. An installation mechanism is fixedly installed inside the uprights 3 at the center of both the front and rear ends, and the lamp tubes 7 are fixedly installed inside the display case through the installation mechanism. The selected design features a base plate 1 for placing exhibits on top, several legs 2 for securing the base plate 1 to the ground, several uprights 3 for mounting transparent panels 5 around the base plate 1, glass panels 4 for viewing the exhibits on the base plate 1, transparent panels 5 for displaying the exhibits on the base plate 1, a cover plate 6 for opening and closing the glass panels 4 for easy placement and removal of exhibits, and light tubes 7 for illuminating the exhibits and ensuring clear visibility. The light tubes 7 integrate a golden, powder-free light source module, emitting uniform and soft light to perfectly showcase the exhibits.

[0020] Furthermore, the installation mechanism includes a vertically formed groove 8 inside the upright 3, a threaded rod 9 vertically rotatably mounted inside the groove 8, a turntable 10 fixedly mounted at the bottom end of the threaded rod 9, and the turntable 10 located below the base plate 1. Threaded blocks 11 are threaded onto the surface of the threaded rod 9, and the threaded blocks 11 are located within the groove 8. Preferably, the groove 8 facilitates the vertical mounting of the threaded rod 9 inside the upright 3, the threaded rod 9 facilitates the mounting of the threaded blocks 11 within the groove 8, the turntable 10 facilitates the rotation of the threaded rod 9, and the threaded blocks 11 facilitate the up-and-down movement of the rectangular sliding rods 12 at both ends. Rotating the turntable 10 facilitates the rotation of the threaded rod 9 within the upright 3, and the rotation of the threaded rod 9 facilitates the up-and-down movement of the threaded blocks 11 within the groove 8, thereby facilitating the up-and-down movement of the rectangular sliding rods 12 at both ends on the base plate 1.

[0021] Furthermore, rectangular slide rods 12 are horizontally fixed at both ends of the threaded block 11, and rectangular rod grooves 13 are vertically opened at both ends of the upright rod 3. The rectangular rod grooves 13 are connected to the grooves 8, and the rectangular slide rods 12 are slidably disposed in the rectangular rod grooves 13. Preferably, the rectangular slide rods 12 facilitate the arrangement of several rectangular slide plates 14 on both sides of the threaded block 11. The rectangular rod grooves 13 facilitate the vertical movement of the rectangular slide rods 12 at both ends of the upright rod 3. The vertical movement of the threaded block 11 facilitates the vertical movement of the rectangular slide rods 12 at both ends within the two rectangular rod grooves 13, thereby facilitating the threaded block 11 to pass through the upright rod 3 and drive the rectangular slide rods 12 at both ends to move vertically.

[0022] Furthermore, a plurality of rectangular sliding plates 14 are slidably disposed on the surface of the rectangular slide rod 12. An L-shaped plate 15 is fixedly disposed at the inner end of each of the rectangular sliding plates 14. A screw 16 is rotatably disposed at the center of the inner end of each of the L-shaped plates 15, and the screw 16 is located above the rectangular sliding plate 14. Preferably, the rectangular sliding plates 14 facilitate the placement of the L-shaped plates 15 on the rectangular slide rod 12, the L-shaped plates 15 facilitate the placement of the screw 16 on the rectangular sliding plates 14, and the screw 16 facilitates the movement of the clamping plate 17. The movement of the rectangular sliding plates 14 on the rectangular slide rod 12 facilitates the adjustment of the distance between the rectangular sliding plates 14, thereby facilitating the adaptation of lamp tubes 7 of different lengths, and thus facilitating the installation and maintenance of lamps of different lengths.

[0023] Furthermore, a bearing 18 is threaded onto the inner end of the screw 16, and a clamping plate 17 is fixedly mounted on the inner end of the bearing 18. The clamping plate 17 is located on the rectangular slide plate 14, and its inner end is in contact with the lamp tube 7. A handle 19 is fixedly mounted on the outer end of the screw 16, and the handle 19 is located outside the L-shaped plate 15. Preferably, the bearing 18 facilitates the mounting of the clamping plate 17 on the inner end of the screw 16, and the clamping plate 17 facilitates the front and rear fixing of the lamp tube 7. The handle 19 facilitates the rotation of the screw 16, and the rotation of the handle 19 facilitates the rotation of the screw 16 within the L-shaped plate 15. The rotation of the screw 16 facilitates the movement of the bearing 18, thereby facilitating the movement of the clamping plate 17 on the rectangular slide plate 14, and thus facilitating the fixing of the lamp tube 7 on the rectangular slide plate 14. This makes it convenient for the installation and maintenance of lamps of different sizes.

[0024] Furthermore, the internal light of the lamp tube 7 is composed of a powder-free light source spectrum consisting of a yellow LED chip with a peak wavelength in the 550-570nm band and a red LED chip with a peak wavelength in the 610-630nm band. Preferably, through precise, flexible and stable control of the powder-free light source spectrum, the special requirements of exhibits such as gold jewelry and ancient bronzes for spectral characteristics under different exhibition scenarios can be met, thereby improving the display effect, effectively extending the service life of the exhibits and reducing maintenance costs.

[0025] Furthermore, for the display of gold jewelry, precise golden light spectrum output is achieved by accurately controlling the current ratio of yellow and red LED chips. A constant current drive circuit independently powers the two types of chips and connects them to a microcontroller. The microcontroller dynamically adjusts the chip current ratio based on preset spectral parameters or real-time feedback signals. For example, when highlighting the brightness of gold jewelry, the microcontroller can increase the current ratio of the yellow chip to 60%-65%, while correspondingly decreasing the current ratio of the red chip to 35%-40%. When displaying ancient bronze artifacts with a rustic feel, the current ratio of the yellow chip can be adjusted to 55%-60%, and the current ratio of the red chip increased to 40%-45%, thus creating a golden light atmosphere that better suits the characteristics of the exhibits.

[0026] Furthermore, intelligent chip layout switching technology has been developed for exhibits of different sizes and shapes. When displaying small jewelry, a ring or circular chip layout is used to ensure that light can evenly surround the exhibit, reducing shadows and glare. When displaying large bronze artifacts and other exhibits, a matrix chip layout is switched to ensure that the entire surface of the exhibit receives uniform illumination. The microcontroller automatically controls the chip layout switching circuit based on exhibit information or user input commands, enabling rapid switching between different layout modes and further optimizing the spectral distribution on the exhibit.

[0027] In this invention, during use, the cover plate 6 is opened using a special tool, and then light tubes 7 of different sizes are placed onto several rectangular sliding plates 14. The rectangular sliding plates 14 are then moved on rectangular sliding rods 12 according to the length of the light tubes 7, thus facilitating the adjustment of the distance between several clamping plates 17 to accommodate light tubes 7 of varying lengths. Then, rotating two turntables 10 causes two threaded rods 9 to rotate within two uprights 3. The rotation of the two threaded rods 9 causes two threaded blocks 11 to move upward within grooves 8. The upward movement of the two threaded blocks 11 causes the rectangular sliding rods 12 at both ends to move downward on both sides of the uprights 3. The rectangular sliding rods 12 at both ends move upward, driving two sets of rectangular sliding plates 14 to move upward, thus facilitating the vertical fixation of the light tubes 7 on the rectangular sliding plates 14. Then, the handles 19 are rotated to drive the screws 16 to rotate within the L-shaped plates 15, which in turn push the clamps 17 on the rectangular sliding plates 14 to move outward through the bearings 18. This causes the clamps 17 to move outward, fixing the light tubes 7 on the rectangular sliding plates 14 front and back, thus facilitating the installation and maintenance of light fixtures of different sizes and lengths, thereby reducing the operating cost of the exhibition cabinet.

[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.
