Description

Technical Field

[0001] The present invention relates to the technical field of display cabinets, and particularly to an adjustable lamp applied to a display cabinet. Background Art

[0002] In the display industry, as the main display carrier for items such as goods, artworks or cultural relics, the internal lighting effect of a display cabinet is crucial for enhancing the display effect, attracting the attention of viewers, and protecting the displayed items. Traditional display cabinet lamps often adopt a fixed design and cannot be flexibly adjusted according to the characteristics of the displayed items or display requirements, resulting in a single lighting effect and being difficult to meet diverse display needs. To solve this problem, in recent years, adjustable lamp technology has gradually been applied to display cabinets. Such lamps achieve precise adjustment of the lighting angle, brightness, and color temperature by adopting advanced mechanical structures and electronic control technologies. Users can flexibly adjust the lighting parameters of the lamps according to factors such as the shape, material, color of the displayed items, and the display environment to achieve the best display effect. During the current use of display cabinets, in order to enhance the display effect of exhibits, softening paper is usually installed in front of the lighting lamps. This approach utilizes the characteristics of the softening paper to soften the light and reduce glare, making the exhibits appear more gentle and natural when displayed. In addition, the staff can further enhance the light softening effect by increasing the number of layers of softening paper. However, when multiple layers of softening paper are used simultaneously, the softening paper closest to the lighting lamp is usually more severely damaged than the softening paper in other positions due to direct exposure to the light and temperature. Therefore, the staff needs to regularly check and replace the top layer of softening paper, which increases the workload of the staff to a certain extent. Summary of the Invention

[0003] The purpose of the present invention is to solve the problems in the background art and propose an adjustable lamp applied to a display cabinet.

[0004] To achieve the above object, the present invention adopts the following technical solution: An adjustable lamp for a display cabinet, comprising a base, a double-layer protective glass is fixedly installed on the top of the base, a cylinder body is fixedly installed on the top of the double-layer protective glass, an LED lamp is fixedly installed on the top of the inner cavity of the cylinder body, a sinking cavity and a flipping cavity are arranged inside the cylinder body, two electric push rods are fixedly installed on the bottom of the inner cavity of the cylinder body, the telescopic ends of the tops of the two electric push rods are fixedly installed with cross plates, outer limiting rings and inner limiting rings are welded on the bottoms of the two cross plates, motors are fixedly installed on the inner side walls of the two outer limiting rings, discs are fixedly installed at the output ends of the two motors, an installation frame one is welded between the two discs, a soft light paper one is arranged inside the installation frame one, two symmetric installation slots one are opened on the upper and lower sides of the two discs, sliding rods one are welded on the inner side walls of each installation slot one, limiting rods are slidably arranged on the outer peripheral walls of each sliding rod one, springs one are wound around the outer peripheral walls of each sliding rod one, and each spring one is respectively located between the corresponding limiting rod and the cavity wall of the corresponding installation slot one, vertical plates are welded on the outer side walls of every two limiting rods, semi-circular plates are welded on the side walls of each vertical plate, an installation frame two is welded between the side walls of every two semi-circular plates, soft light papers two are arranged inside the two installation frames two. The arranged electric push rods drive the soft light paper one and the soft light paper two to move upward, so that the soft light paper one and the soft light paper two move out of the sinking cavity and move to the central position inside the flipping cavity. Subsequently, the arranged motors drive the discs, the installation frame one and the soft light paper one to flip 180 degrees. The arranged discs drive the sliding rods one, the limiting rods, the vertical plates, the semi-circular plates, the installation frame two and the soft light paper two to flip 180 degrees. The arranged soft light paper one and the soft light paper two are flipped synchronously, so that the soft light papers two on the upper and lower sides are swapped, thereby reducing the loss of the single-sided soft light paper two and improving the service life of the whole group of soft light papers.

[0005] In the above adjustable lamp applied to a display cabinet, a plurality of air chambers are fixedly installed at the bottom of the inner cavity of the cylinder body. Each air chamber is communicated with an intake pipeline one and an intake pipeline two at the top, and each air chamber is communicated with an exhaust pipeline one and an exhaust pipeline two at the bottom. A second sliding rod is slidably arranged on the side wall of each air chamber. A slider is welded between the outer sides of every two second sliding rods located outside the air chamber. A second spring is wound around the outer peripheral wall of each second sliding rod, and each second spring is respectively located between the corresponding slider and the side wall of the corresponding air chamber. A piston plate is welded between the inner sides of every two second sliding rods located in the inner cavity of the air chamber. When the electric push rod drives the first soft light paper and the second soft light paper to move to the middle position inside the flipping cavity, the set slider enters the gap between the outer limiting ring and the inner limiting ring. When the motor drives the limiting rod to flip, the set limiting rod will push the slider to move towards the air chamber. The set slider drives the piston plate to move through the second sliding rod. The set piston plate extrudes the space on its right side, so that the gas inside the space on the right side of the piston plate enters the inner cavity of the cylinder body through the exhaust pipeline one. Then the air flow flows upward and successively passes over the first soft light paper, the second soft light paper and the LED lamp. Finally, the gas is discharged from the inner cavity of the cylinder body through the exhaust pipeline three. During this process, the flowing gas will carry away the heat of the first soft light paper, the second soft light paper and the LED lamp, so as to realize the heat dissipation of the first soft light paper and the second soft light paper and the secondary heat dissipation of the LED lamp.

[0006] In the above adjustable lamp applied to a display cabinet, two exhaust pipelines three are communicated with the top of the cylinder body, and the intake ends of the two exhaust pipelines three respectively extend to the left and right sides of the LED lamp. When the first soft light paper and the second soft light paper move upward, the air at their tops can only be discharged from the inner cavity of the cylinder body through the exhaust pipelines three. Since the intake ends of the exhaust pipelines three extend to the sides of the LED lamp, part of the heat emitted by the LED lamp will be carried away when the air is discharged, so as to conduct preliminary heat dissipation for the LED lamp.

[0007] In the above adjustable lamp applied to a display cabinet, a one-way ventilation valve is arranged in the inner cavity of each of the intake pipeline one, the intake pipeline two, the exhaust pipeline one, the exhaust pipeline two and the exhaust pipeline three.

[0008] In the above adjustable lamp applied to a display cabinet, telescopic rods are fixedly installed in the two side grooves of the sinking cavity. The telescopic ends at the tops of the two telescopic rods are fixedly installed with semi-circular plates. A third spring is wound around the outer peripheral walls of the two telescopic rods. During the process that the electric push rod drives the first soft light paper and the second soft light paper to move out of the sinking cavity, the set semi-circular plates tightly abut against the bottoms of the outer limiting ring and the inner limiting ring under the action of the elastic force of the third spring, and the gap between the outer limiting ring and the inner limiting ring is sealed by means of the semi-circular plates.

[0009] In the above adjustable lamp applied to a display cabinet, a plurality of mounting holes are formed in the outer peripheral wall of the cylinder body.

[0010] In the adjustable lamp for a display cabinet described above, sliding groove holes are formed on the outer peripheral walls of each of the limiting rods, and each of the first sliding rods is slidably disposed inside the corresponding sliding groove hole.

[0011] Compared with the existing technology, the advantages of the adjustable lamp for a display cabinet are as follows:

[0012] 1. Every once in a while, the first soft light paper and the second soft light paper are synchronously flipped, so that the second soft light papers on the upper and lower sides are swapped, thereby reducing the loss of the second soft light paper on one side and improving the service life of the whole group of soft light papers.

[0013] 2. When the first soft light paper and the second soft light paper move upward, the air at their tops can only be discharged from the inner cavity of the cylinder through the third air outlet pipeline. Since the air inlet end of the third air outlet pipeline extends to the side of the LED lamp, part of the heat emitted by the LED lamp will be carried away when the air is discharged, thereby preliminarily dissipating the heat of the LED lamp.

[0014] 3. The air flow flows upward and successively passes over the first soft light paper, the second soft light paper and the LED lamp. The flowing air will carry away the heat of the first soft light paper, the second soft light paper and the LED lamp, thereby realizing the heat dissipation of the first soft light paper and the second soft light paper and the secondary heat dissipation of the LED lamp. In addition, the two second soft light papers are gradually separated from the first soft light paper, making it easier for the flowing air to carry away the heat on the surfaces of the second soft light paper and the first soft light paper, and thus making the heat dissipation effect better.

[0015] 4. The piston plate provided gradually resets under the elastic force of the second spring. During this process, the piston plate provided will squeeze the space on its left side, so that the gas in the space on its left side enters the inner cavity of the cylinder, thereby realizing the re-heat dissipation of the first soft light paper, the second soft light paper and the LED lamp.

[0030] Refer to Figures 1 - 11, An adjustable lamp applied to a display cabinet, comprising a base 1. A double-layer protective glass 2 is fixedly installed on the top of the base 1.

A sunken cavity 5 and a flipping cavity 6 are arranged inside the cylinder 3. Two electric push rods 7 are fixedly installed on the bottom of the inner cavity of the cylinder 3. The telescopic ends of the tops of the two electric push rods 7 are both fixedly installed with cross plates 8. Outer limiting rings 9 and inner limiting rings 10 are welded to the bottoms of the two cross plates 8. Motors 11 are fixedly installed on the inner side walls of the two outer limiting rings 9. Discs 12 are fixedly installed at the output ends of the two motors 11. An installation frame one 13 is welded between the two discs 12. A soft light paper one 14 is arranged inside the installation frame one 13. Two symmetrical installation grooves one 15 are opened on the upper and lower sides of the two discs 12. Slide rods one 16 are welded on the inner side walls of each installation groove one 15. Limiting rods 17 are slidably arranged on the outer peripheral walls of each slide rod one 16. Sliding groove holes 38 are opened on the outer peripheral walls of each limiting rod 17, and each slide rod one 16 is respectively slidably arranged inside the corresponding sliding groove hole 38. Spring one 18 is wound around the outer peripheral wall of each slide rod one 16, and each spring one 18 is respectively located between the corresponding limiting rod 17 and the cavity wall of the corresponding installation groove one 15. Vertical plates 19 are welded on the outer side walls of every two limiting rods 17. Semi-circular plates 20 are welded on the side walls of each vertical plate 19. Installation frames two 21 are welded between the side walls of every two semi-circular plates 20. Soft light paper two 22 is arranged inside the two installation frames two 21. The electric push rods 7 arranged drive the soft light paper one 14 and the soft light paper two 22 to move upward, so that the soft light paper one 14 and the soft light paper two 22 move out of the sunken cavity 5 and move to the central position inside the flipping cavity 6. Subsequently, the motors 11 arranged drive the discs 12, the installation frame one 13 and the soft light paper one 14 to flip 180 degrees. The discs 12 arranged drive the slide rods one 16, the limiting rods 17, the vertical plates 19, the semi-circular plates 20, the installation frames two 21 and the soft light paper two 22 to flip 180 degrees. The soft light paper one 14 and the soft light paper two 22 arranged flip synchronously, so that the soft light paper two 22 on the upper and lower sides is swapped, thereby reducing the loss of the soft light paper two 22 on one side and improving the service life of the whole group of soft light papers.

[0031] Further, a plurality of air chambers 23 are fixedly installed at the bottom of the inner cavity of the cylinder body 3. An air inlet pipeline one 24 and an air inlet pipeline two 25 are communicated with the top of each air chamber 23. An air outlet pipeline one 26 and an air outlet pipeline two 27 are communicated with the bottom of each air chamber 23. A second slide bar 28 is slidably arranged on the side wall of each air chamber 23. A slider 29 is welded between the sides of every two second slide bars 28 located outside the air chamber 23. A second spring 30 is wound around the outer peripheral wall of each second slide bar 28, and each second spring 30 is respectively located between the corresponding slider 29 and the side wall of the corresponding air chamber 23. A piston plate 31 is welded between the sides of every two second slide bars 28 located inside the air chamber 23. Telescopic rods 34 are fixedly installed in the two side grooves of the sinking cavity 5. Semi-circular plates 35 are fixedly installed at the telescopic ends of the tops of the two telescopic rods 34. A third spring 36 is wound around the outer peripheral walls of the two telescopic rods 34. Two air outlet pipelines three 32 are communicated with the top of the cylinder body 3, and the air inlet ends of the two air outlet pipelines three 32 respectively extend to the left and right sides of the LED lamp 4. During the process of the electric push rod 7 driving the first soft light paper 14 and the second soft light paper 22 to move out of the sinking cavity 5, the semi-circular plate 35 arranged tightly abuts against the bottoms of the outer limiting ring 9 and the inner limiting ring 10 under the action of the elastic force of the third spring 36, and the gap between the outer limiting ring 9 and the inner limiting ring 10 is sealed by means of the semi-circular plate 35, so that the air at the top of the first soft light paper 14 and the second soft light paper 22 can only be discharged from the inner cavity of the cylinder body 3 through the air outlet pipeline three 32 during the upward movement. Since the air inlet end of the air outlet pipeline three 32 extends to the side of the LED lamp 4, a part of the heat emitted by the LED lamp 4 will be taken away when the air is discharged, so as to conduct preliminary heat dissipation for the LED lamp 4.

[0032] Further, a plurality of mounting holes 37 are formed in the outer peripheral wall of the cylinder body 3. One-way ventilation valves 33 are arranged in the inner cavities of each air inlet pipeline one 24, air inlet pipeline two 25, air outlet pipeline one 26, air outlet pipeline two 27 and air outlet pipeline three 32. The air inlet pipeline one 24 and the air inlet pipeline two 25 arranged are respectively installed inside the corresponding mounting holes 37. The one-way ventilation valve 33 inside the air inlet pipeline one 24 only allows external gas to enter the space on the right side of the piston plate 31. The one-way ventilation valve 33 inside the air inlet pipeline two 25 only allows external gas to enter the space on the left side of the piston plate 31. The one-way ventilation valve 33 inside the air outlet pipeline one 26 only allows the gas in the space on the right side of the piston plate 31 to enter the inner cavity of the cylinder body 3. The one-way ventilation valve 33 inside the air outlet pipeline two 27 only allows the gas in the space on the left side of the piston plate 31 to enter the inner cavity of the cylinder body 3. The one-way ventilation valve 33 inside the air outlet pipeline three 32 only allows the gas in the inner cavity of the cylinder body 3 to be discharged from the inner cavity of the cylinder body 3.

[0033] Working principle: When in use, the light emitted by the set LED lamp 4 passes through the first soft light paper 14 and the second soft light paper 22 and irradiates on the exhibits inside the double-layer protective glass 2. The set first soft light paper 14 and second soft light paper 22 can soften the light and reduce glare, making the exhibits softer and more natural during display; every once in a while, the set electric push rod 7 drives the first soft light paper 14 and the second soft light paper 22 to move upward, so that the first soft light paper 14 and the second soft light paper 22 move out of the sinking cavity 5 and move to the central position inside the flipping cavity 6. Subsequently, the set motor 11 drives the disc 12, the first mounting frame 13 and the first soft light paper 14 to flip 180 degrees. The set disc 12 drives the first sliding rod 16, the limiting rod 17, the vertical plate 19, the semi-circular plate 20, the second mounting frame 21 and the second soft light paper 22 to flip 180 degrees. The set first soft light paper 14 and second soft light paper 22 flip synchronously, so that the second soft light papers 22 on the upper and lower sides are swapped, thereby reducing the loss of the single-sided second soft light paper 22 and improving the service life of the entire set of soft light papers;

[0034] During the process of the electric push rod 7 driving the first soft light paper 14 and the second soft light paper 22 to move out of the sinking cavity 5, the set semi-circular plate 35 tightly abuts against the bottoms of the outer limiting ring 9 and the inner limiting ring 10 under the elastic force of the third spring 36, and seals the gap between the outer limiting ring 9 and the inner limiting ring 10 with the help of the semi-circular plate 35, so that the air at the top of the first soft light paper 14 and the second soft light paper 22 can only be discharged from the inner cavity of the cylinder 3 through the third air outlet pipeline 32 during the upward movement. Since the air inlet end of the third air outlet pipeline 32 extends to the side of the LED lamp 4, part of the heat emitted by the LED lamp 4 will be taken away when the air is discharged, so as to conduct preliminary heat dissipation for the LED lamp 4; it should be noted that the set third air outlet pipeline 32 can be connected to an external pipeline, which is convenient for discharging the hot air inside the cylinder 3;

[0035] When the first soft light paper 14 and the second soft light paper 22 move to the central position inside the flipping cavity 6 and the motor 11 drives the first soft light paper 14 and the second soft light paper 22 to flip, since two grooves are provided on the inner ring surfaces of the outer limiting ring 9 and the inner limiting ring 10, during the process of flipping to nearly 90 degrees, the set limiting rod 17 moves into the grooves of the outer limiting ring 9 and the inner limiting ring 10 under the elastic force of the first spring 18. At this time, the set limiting rod 17 drives the vertical plate 19, the semi-circular plate 20, the second mounting frame 21 and the second soft light paper 22 to move away from the first soft light paper 14, so that the two second soft light papers 22 are gradually separated from the first soft light paper 14; it should be noted that the position of the set first soft light paper 14 remains unchanged, and the two symmetrically arranged second soft light papers 22 gradually move away from the first soft light paper 14. When flipping to 90 degrees, the two symmetrically arranged second soft light papers 22 move to the farthest distance from the first soft light paper 14;

[0036] When the electric push rod 7 drives the soft light paper one 14 and the soft light paper two 22 to move to the central position inside the flipping cavity 6, the set slider 29 enters the gap between the outer limiting ring 9 and the inner limiting ring 10. When the motor 11 drives the limiting rod 17 to flip, the set limiting rod 17 will push the slider 29 to move towards the gas chamber 23. The set slider 29 drives the piston plate 31 to move through the second slide rod 28. The set piston plate 31 squeezes the space on its right side, so that the gas inside the space on the right side of the piston plate 31 enters the inner cavity of the cylinder body 3 through the first air outlet pipeline 26. Subsequently, the air flow flows upward and successively passes over the soft light paper one 14, the soft light paper two 22 and the LED lamp 4. Finally, the gas is discharged from the inner cavity of the cylinder body 3 through the third air outlet pipeline 32. During this process, the flowing gas will carry away the heat of the soft light paper one 14, the soft light paper two 22 and the LED lamp 4, so as to realize the heat dissipation of the soft light paper one 14 and the soft light paper two 22 and the secondary heat dissipation of the LED lamp 4; In addition, the two set soft light papers two 22 are gradually separated from the soft light paper one 14, so that the flowing gas can more easily carry away the heat on the surfaces of the soft light paper two 22 and the soft light paper one 14, and further make the heat dissipation effect better; When the motor 11 drives the soft light paper one 14 and the soft light paper two 22 to flip from 90 degrees to 180 degrees, the set limiting rod 17 drives the soft light paper two 22 to gradually reset; The set piston plate 31 gradually resets under the elastic force of the second spring 30. During this process, the set piston plate 31 will squeeze the space on its left side, so that the gas in the space on its left side enters the inner cavity of the cylinder body 3, thereby realizing the re-heat dissipation of the soft light paper one 14, the soft light paper two 22 and the LED lamp 4; It should be noted that the set first air inlet pipeline 24 and the second air inlet pipeline 25 can both be connected to the external pipeline, which is convenient for sucking the cold air outside the cylinder body 3 to participate in the heat dissipation operation.

[0037] Further explanation, the above fixed connection, unless otherwise clearly specified and limited, should be understood in a broad sense. For example, it can be welding, gluing, or integrally formed setting, etc., which are common means well-known to those skilled in the art.

[0038] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
