Description

Technical Field

[0001] This utility model relates to a track spotlight, and more particularly to a track spotlight with a built-in light control device, belonging to the field of track spotlight technology. Background Technology

[0002] To best showcase products or objects, people need to purchase various lighting fixtures with different color temperatures and brightness specifications. When the products or objects in the display area are changed, the track lighting with the current color temperature and brightness may become unsuitable again. Therefore, in order to take into account the display effects of different products or objects, external control devices or systems such as SCR dimmers, 0-10V dimmers, DMX512 dimmers or systems, and DALI dimmers are used to control the light.

[0003] In the prior art, such as the utility model with application number 202021959912.9, a track spotlight with a built-in light control device is disclosed. The spotlight itself has a built-in light control structure, which is different from most lamps on the market that use independent light control systems or devices. It uses a light control technology that combines a dual-color COB light source with a toggle switch to control the current and voltage output circuit of the drive power supply device. This reduces complicated wiring work, simplifies the wiring structure, and can meet the needs of various scenarios. The light control is convenient and easy.

[0004] The above-mentioned applications still have shortcomings:

[0005] This type of track spotlight with built-in light control cannot adjust the height of the spotlight, resulting in a fixed lighting distance. It is difficult to adapt to spaces with varying heights or complex scenes, and is prone to problems such as light attenuation and blind spots. When the scene changes, the light fixtures need to be reinstalled, which is not flexible and efficient, limiting its application in dynamic lighting scenarios.

[0006] To address this issue, a track spotlight with built-in light control was designed. Summary of the Invention

[0007] The main purpose of this invention is to provide a track spotlight with a built-in light control device to solve the problems mentioned in the background art.

[0010] Preferably, the protective component includes an external threaded ring, an internal threaded ring, and a second magnetic ring. The external threaded rings are respectively fitted and installed in the middle and lower positions of the spotlight body. The internal threaded rings are slidably fitted and installed on the outside of the spotlight body, and the internal threaded rings are located between the external threaded rings. U-shaped rods are symmetrically arranged at the bottom of the internal threaded rings. A semi-circular plate is rotatably installed in the middle position of each U-shaped rod. A first magnetic ring is fixed on the side of each semi-circular plate near the spotlight body. The second magnetic ring is installed at the bottom end of the spotlight body.

[0011] Preferably, both ends of the bidirectional screw penetrate and extend to the outside of the square tube 2, and both ends of the bidirectional screw are fixed with a rotating handle.

[0012] Preferably, an anti-slip layer is provided on one outer side of the clamping plate, and one end of the clamping plate is slidably connected to the inner wall of the square tube.

In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. Example 1

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment proposes a track spotlight with a built-in light control device, including a spotlight body 1, a protective component 2 on the spotlight body 1, a boom 3 mounted on the top of the spotlight body 1, the boom 3 and the spotlight body 1 being hinged for easy adjustment of the tilt angle of the spotlight body 1, a lead screw 4 fixed to the top of the boom 3, the top of the boom 3 and the lead screw 4 being fixedly connected by screw threads, a block 5 fixed to the top of the lead screw 4, a square tube 6 slidably connected to the outside of the block 5, and a square tube 6 fixed to the bottom of the square tube 6. A semi-circular cover 7 is fixed, and a turntable 8 rotates inside the semi-circular cover 7. A screw hole is opened in the middle of the turntable 8 to be threadedly connected to the lead screw 4. The turntable 8 is threadedly connected to the lead screw 4 through the screw hole. A square tube 9 slides on the outside of the square tube 1 6. In order to prevent the square tube 1 6 from sliding too much and causing it to detach or collide with the square tube 2 9, a buffer rubber block can be set at the limit position of the sliding stroke inside the square tube 2 9. When the square tube 1 6 slides to the limit position, the buffer rubber block can play a buffering role and protect the structure of the device from damage.

[0033] A bidirectional screw 11 is symmetrically inserted through the bottom side wall of the second square tube 9. A through hole adapted to the outer diameter of the bidirectional screw 11 is opened at the corresponding position of the second square tube 9. The bidirectional screw 11 passes through the through hole. The two ends of the bidirectional screw 11 on the outside of the second square tube 9 are fastened by limiting rings to limit the bidirectional screw 11 to the lower end of the second square tube 9. A clamping plate 12 is symmetrically arranged on the bidirectional screw 11 and inside the first square tube 6. A sliding hole 10 is opened at the connection between the first square tube 6 and the bidirectional screw 11. A sliding seat 14 is rotatably installed on the top of the second square tube 9.

[0034] Rotate the two bidirectional screws 11 respectively. The bidirectional screws 11 drive the outer clamping plates 12 to move towards the center and away from the inner wall of the square tube 6. Then, they pull the square tube 6 and the spotlight body 1 downward. The sliding hole 10 on the square tube 6 slides downward along the outer side of the bidirectional screws 11. After the spotlight body 1 slides down to a suitable height, rotate the two bidirectional screws 11 in the opposite direction to make the outer clamping plates 12 move to both sides and fit tightly against the inner wall of the square tube 6. This fixes the relative position of the square tube 6 and the second square tube 9, and fixes the height of the spotlight body 1. Then rotate the turntable 8. Under the sliding relationship between the square tube 6 and the block 5, the lead screw 4 is limited to prevent the lead screw 4 from rotating with the turntable 8. The rotation of the turntable 8 drives the lead screw 4 to move downward. The lead screw 4 drives the spotlight body 1 to make a micro-adjustment downward, thereby adjusting the height of the spotlight body 1 more precisely. Example 2

[0035] The solution in Example 1 will be further described below with reference to its specific working method.

[0036] like Figure 1 , Figure 4 and Figure 5 As shown, in a preferred embodiment, based on the above method, the protective component 2 further includes an external threaded ring 201, an internal threaded ring 202 and a magnetic ring 206, with the external threaded ring 201 respectively fitted and installed in the middle and lower positions of the spotlight body 1.

[0037] The internal threaded ring 202 is slidably mounted on the outside of the spotlight body 1, and the internal threaded ring 202 is located between the external threaded rings 201. The sliding range of the internal threaded ring 202 on the outside of the spotlight body 1 is limited by the external threaded rings 201 at the upper position and the external threaded rings 201 at the lower position. When the internal threaded ring 202 slides to the upper limit position, the internal thread of the internal threaded ring 202 is tightly engaged with the external thread of the upper external threaded ring 201, thereby limiting the internal threaded ring 202 and the semi-circular plate 204. When the internal threaded ring 202 slides to the lower limit position, the internal thread of the internal threaded ring 202 is tightly engaged with the external thread of the lower external threaded ring 201, at which time the semi-circular plate 204 can be flipped and spliced.

[0038] The external threaded ring 201 and the internal threaded ring 202 are made of high-strength and corrosion-resistant metal materials, such as aluminum alloy, which have good mechanical properties and corrosion resistance. This ensures that the threaded structure is not easily damaged or rusted during long-term use, thus ensuring the normal operation and service life of the protective component 2. The bottom of the internal threaded ring 202 is symmetrically provided with U-shaped rods 203. A semi-circular plate 204 is rotatably installed in the middle of each U-shaped rod 203. A magnetic ring 205 is fixed on the side of the semi-circular plate 204 near the spotlight body 1. A magnetic ring 206 is installed at the bottom of the spotlight body 1. The magnetic rings 205 and 206 are made of neodymium iron boron permanent magnet material, which has the characteristics of high remanence, high coercivity and high magnetic energy product. This provides a sufficiently strong and stable adsorption force to ensure that the semi-circular plate 204 is stably shielded at the bottom of the spotlight body 1 after splicing.

[0039] When the spotlight body 1 is not in use for illumination, rotate the internal threaded ring 202 to separate it from the external threaded ring 201 located at the top of the spotlight body 1, thus releasing the restriction on the internal threaded ring 202 and the semicircular plate 204. Slide the internal threaded ring 202 downwards until it reaches the external threaded ring 201 at the lower position. Rotate the internal threaded ring 202 again to connect it with the external threaded ring 201 at the lower position. Flip the semicircular plates 204 inwards so that the ends of the two sets of semicircular plates 204 are joined together and cover the bottom of the spotlight body 1. At the same time, the magnetic ring 205 on the semicircular plate 204 is attracted to the magnetic ring 206 at the bottom of the spotlight body 1, thus completing the protection of the bottom of the spotlight body 1.

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment, based on the above method, both ends of the bidirectional screw 11 extend through and to the outside of the square tube 2 9, and both ends of the bidirectional screw 11 are fixed with a handle 13.

[0041] The bidirectional screw 11 can be easily rotated via the handle 13, making operation labor-saving and efficient, and improving the convenience of height adjustment.

[0042] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, a further anti-slip layer is provided on one outer side of the clamping plate 12. The anti-slip layer material can be silicone rubber, which has good anti-slip properties and a high surface friction coefficient. When the clamping plate 12 contacts the inner wall of the square tube 6, it can effectively increase the friction force and prevent relative sliding. At the same time, silicone rubber also has properties such as resistance to high and low temperatures and aging resistance, which can adapt to different usage environments and ensure that it can stably play an anti-slip role under various working conditions. Moreover, one end of the clamping plate 12 is slidably connected to the inner wall of the square tube 6.

[0043] The anti-slip layer can increase the friction between the clamp 12 and the inner wall of the square tube 6, making the fixation more stable and reliable, and preventing the spotlight body 1 from shifting due to vibration or external force during use.

[0044] like Figure 4 and Figure 5 As shown, in a preferred embodiment, based on the above method, a reinforcing strip is evenly provided on the outer side of the internal threaded ring 202, and the reinforcing strip is a rubber reinforcing strip.

[0045] Nitrile rubber was selected as the reinforcing strip material. Nitrile rubber has excellent oil resistance, wear resistance, and aging resistance. It can effectively enhance the structural strength of the internal threaded ring 202, resist wear caused by frequent rotation, and absorb external impact to a certain extent, playing a buffering and protective role, extending the service life of the internal threaded ring 202. In addition, the rubber reinforcing strip has a certain friction and elasticity, which facilitates the rotation and use of the internal threaded ring 202 by the operators.

[0046] like Figure 4 As shown, in a preferred embodiment, based on the above method, the bottom of each semicircular plate 204 is further fixed with a limiting strip, and the limiting strip is an arc-shaped limiting strip.

[0047] The arc-shaped limiting strip makes it easier for staff to flip the semicircular plate 204 downwards and unfold it, making it easier to use.

[0048] like Figure 1 As shown, in a preferred embodiment, based on the above method, the turntable 8 is further provided with vertical stripes evenly distributed on its outer side, and the diameter of the turntable 8 is smaller than the diameter of the semi-annular cover 7.

[0049] The vertical stripe design increases the friction between the hand and the turntable 8, making it easier for the operator to apply force to turn the turntable 8 and achieve micro-adjustment of the spotlight body 1; the semi-circular cover 7 matches the shape of the turntable 8, which can play a good role in limiting and protecting the turntable 8, preventing it from shaking or deviating during rotation. Example 3

[0050] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0051] Rotate the two bidirectional screws 11 respectively. The bidirectional screws 11 drive the outer clamping plates 12 to move towards the middle and away from the inner wall of the square tube 6. Then, pull the square tube 6 and the spotlight body 1 downward. The sliding hole 10 on the square tube 6 slides downward along the outer side of the bidirectional screws 11. After the spotlight body 1 slides down to a suitable height, rotate the two bidirectional screws 11 in the opposite direction to make the outer clamping plates 12 move to both sides and fit tightly against the inner wall of the square tube 6, thereby fixing the relative position of the square tube 6 and the square tube 9. At the same time, fix the height of the spotlight body 1. Then rotate the turntable 8. Using the sliding limit of the square tube 6 and the block 5, the screw 4 moves only axially, thereby achieving micro-precision height adjustment of the spotlight body 1. When the spotlight is not used for illumination, rotate the inner threaded ring 202 to disengage it from the outer threaded ring 201 above the spotlight body 1, thereby releasing the limit on the inner threaded ring 202 and the semi-circular plate 204. Slide the inner threaded ring 202 down to the lower outer threaded ring 201, rotate it again to make it threadedly connected, and then flip the semi-circular plate 204 towards the middle to splice it. Utilize the adsorption effect of magnetic ring one 205 and magnetic ring two 206 to cover and protect the bottom of the spotlight body 1.

[0052] The above description is only a further 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 scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
