Description

Technical Field

[0001] This invention relates to the field of discharge lamp technology, and more specifically, to a discharge lamp cooling mechanism and a discharge lamp using the same. Background Technology

[0002] Discharge lamps typically consist of a sealed glass or quartz casing, electrodes, and a filling gas. When a sufficiently high voltage is applied to the electrodes at both ends of the lamp, the gas is ionized, forming a conductive channel. Free electrons are accelerated under the influence of the electric field, colliding with gas atoms or molecules and exciting them to a high-energy state. When these excited atoms or molecules return to their ground state, they release the excess energy in the form of light, thus emitting light. Ultraviolet (UV) exposure lamps are a type of discharge lamp that generates ultraviolet light through gas discharge.

[0003] Currently, multiple discharge lamps are arranged in an array on a lamp holder. The lamp core uses a double-layer tube connection, and the electrode wire passes through a single-layer inner tube. This method allows for a larger inner tube diameter, which can accommodate thicker wires, resulting in better power and heat dissipation. The thickness of the four corners of the glass lamp cup is different. When the lamp body is assembled, the lamp core forms a small, specific angle with the horizontal line, improving the illumination effect.

[0004] However, in practical applications, once the lamp core temperature exceeds the operating threshold, the high heat it generates will be rapidly conducted to the lamp cup through heat transfer, causing both of their temperatures to soar simultaneously. The traditional method of controlling the temperature by adjusting the lamp core power can lower the lamp core temperature to some extent, but the cooling efficiency is extremely low. This causes the lamp core to remain in an overheated operating state for a long time, while the lamp cup is difficult to cool down due to continuous heat absorption. The prolonged high temperature retention of the lamp core and lamp cup, coupled with the slow cooling rate, will inevitably accelerate the aging of the lamp body components and severely shorten its service life. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a discharge lamp cooling mechanism and a discharge lamp using the same.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a discharge lamp cooling mechanism, comprising a cooling mechanism, wherein the cooling mechanism includes a conveying mechanism and a gas supply mechanism, the conveying mechanism includes a liquid inlet tank and a liquid outlet tank, and the gas supply mechanism is installed on the top of the liquid inlet tank.

[0007] Multiple sets of control valves are equidistantly installed on the top of the liquid inlet tank. The inlet of each control valve extends through a pipe to the bottom wall of the liquid inlet tank. The outlet of each control valve is connected to an inlet pipe. The end of the inlet pipe away from the corresponding control valve is connected to a spiral cooling pipe. The spiral cooling pipe is conical. The end of the spiral cooling pipe away from the inlet pipe is connected to a drain pipe. Multiple pump bodies are equidistantly installed on the top of the drain tank. The pump bodies are arranged corresponding to the control valves. The end of the drain pipe away from the spiral cooling pipe is connected to the inlet of the corresponding pump body. The outlet of the pump body is connected to the drain tank.

[0009] By adopting the above technical solution, when the temperature sensor detects that the lamp core is high-temperature, the pump body starts to make the coolant flow through the spiral cooling pipe, and the lamp cup heat transfer quickly cools it down. After the first cooling, the sensor detects again, and only the lamp core that is still hot is cooled a second time. The components at normal temperature are not cooled, which realizes precise differentiated control, avoids energy waste and over-cooling, reduces manual intervention and improves efficiency. Through temperature sensor monitoring and linkage between the air supply valve and the drive cylinder, when the temperature of the lamp body components still exceeds the threshold after cooling, the residual overheated coolant in the liquid inlet pipe is squeezed by air, and the overheated liquid is discharged with the help of the pump body. Then, low-temperature coolant is re-injected, which avoids temperature fluctuations caused by coolant residue, reduces cooling energy consumption and shortens the cycle of secondary cooling.

[0010] The discharge lamp uses the discharge lamp cooling mechanism as described above, including a lamp assembly unit. The lamp assembly unit includes a lamp holder, a base plate installed at the bottom of the lamp holder, and a plurality of adapter holes equidistantly opened at the bottom of the base plate. Each adapter hole is equipped with an assembly component. Each assembly component is provided with a lamp body assembly on its top.

[0013] The present invention is further configured such that: a vertical rod and a lead screw are provided at the top of the first ring body, the vertical rod and the lead screw are arranged opposite to each other, the bottom of the vertical rod is connected to the first ring body, the bottom of the lead screw passes through the first ring body, and two hinge mechanisms are symmetrically hinged to the outer side wall of the second ring body, the two hinge mechanisms are respectively arranged corresponding to the vertical rod and the lead screw, one of the hinge mechanisms is connected to the vertical rod, and the other hinge mechanism is threadedly connected to the lead screw.

[0014] The invention is further configured such that: an L-shaped tube is fitted on the outer wall of the upright, and a Y-shaped frame is horizontally connected to the end of the L-shaped tube away from the upright, and the Y-shaped frame is fitted on the outer wall of the corresponding lamp cup.

[0015] By adopting the above technical solution, when the lamp body assembly needs to be assembled, the ceramic lamp holder is placed diagonally on top of the four support seats. The four support seats cooperate to position the ceramic lamp holder. Then, the Y-shaped frame presses down on the outside of the ceramic lamp holder, and the corresponding pressure rods and springs are pressed down at the four corners of the ceramic lamp holder. The four sets of pressure rods and springs cooperate to compensate for the differences at the four corners. The support seats and the Y-shaped frame cooperate to achieve the assembly and clamping of the ceramic lamp holder. There is no need to worry about the thickness of the four corners of the lamp holder, and the assembly can be completed directly.

[0016] By setting up an adjustment component, which is located on the side of the lamp holder, the electric slider moves the bracket and the various components mounted on the bracket to the side of the lamp holder in the initial state. Then the fixed plate swings to the vertical state. At this time, the adjustment component does not block the illumination of each lamp component, reducing the space occupied above the lamp components.

[0017] The present invention is further configured such that: the adjustment component includes two sets of guide rails symmetrically installed at the bottom of the lamp holder, each guide rail has an electric slider slidably connected to its bottom, each electric slider has a bracket installed at its bottom, a rotating shaft is rotatably connected between the two brackets, a fixing plate is installed on the outer side wall of the rotating shaft, a drive motor is installed on one side of one of the brackets, the output end of the drive motor is connected to one end of the rotating shaft, and an electric clamp is provided on the side wall of the fixing plate.

[0018] The present invention is further configured such that: an electric slide rail is installed on the side wall of the fixed plate, a slide table is slidably connected to the side wall of the electric slide rail, a movable platform is slidably connected to the side wall of the slide table, and the electric slider is provided with a side of the movable platform away from the slide table.

[0020] By adopting the above technical solution, when the lamp assembly needs angle and orientation adjustment, the electric clamp is moved to the underside of the corresponding lead screw and clamped. Then, the assembly motor drives the rotating plate to rotate, which causes the electric clamp to rotate around the output end of the assembly motor. At this time, the electric clamp drives the lead screw to move, and the lead screw drives the first ring to rotate during the movement, thereby adjusting the orientation of the lamp assembly. After the orientation adjustment is completed, the rotary motor drives the electric clamp to rotate, and the electric clamp clamps and rotates the lead screw, thereby adjusting the illumination angle of the second ring and the lamp assembly, increasing the illumination range of the lamp assembly.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] (1) When the temperature sensor detects that the lamp core is hot, the pump starts to make the coolant flow through the spiral cooling tube and cool down quickly through the heat transfer of the lamp cup. After the first cooling, the sensor detects again and only the lamp core that is still hot is cooled down a second time. The components at normal temperature are not cooled, which realizes precise differential control, avoids energy waste and excessive cooling, reduces manual intervention and improves efficiency.

[0023] (2) By setting up pressure rods and bearing seats, when the lamp body assembly needs to be assembled, the ceramic lamp holder is placed diagonally on top of the four bearing seats. The four bearing seats cooperate to position the ceramic lamp holder. Then, the Y-shaped frame presses down on the outside of the ceramic lamp holder. The corresponding pressure rods and springs are pressed down at the four corners of the ceramic lamp holder. The four sets of pressure rods and springs cooperate to compensate for the differences at the four corners. The bearing seats and the Y-shaped frame cooperate to achieve the assembly and clamping of the ceramic lamp holder. There is no need to worry about the thickness of the four corners of the lamp holder, and the assembly can be completed directly.

[0024] (3) By setting the adjustment component, since the adjustment component is set on the side of the lamp holder, that is, when the adjustment component is in the initial state, the electric slider drives the bracket and the various parts installed on the bracket to move to the side of the lamp holder, and then the fixed plate swings to the vertical state. At this time, the adjustment component does not block the lamp body components when they are irradiated, thus reducing the space occupied above the lamp body components.

[0025] (4) When the lamp assembly needs to be adjusted in angle and orientation, the electric clamp is moved to the bottom of the corresponding lead screw and clamped. Then, the assembly motor drives the rotating plate to rotate, which causes the electric clamp to rotate around the output end of the assembly motor. At this time, the electric clamp drives the lead screw to move. When the lead screw moves, it drives the first ring to rotate, thereby adjusting the orientation of the lamp assembly. After the orientation is adjusted, the rotating motor drives the electric clamp to rotate, and the electric clamp clamps and rotates the lead screw, thereby adjusting the illumination angle of the second ring and the lamp assembly and increasing the illumination range of the lamp assembly.

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0047] Please see Figures 1-12 The present invention provides the following technical solutions:

[0048] Example 1, see Figures 1-5 The discharge lamp cooling mechanism includes a cooling mechanism 1, which is used to cool the discharge lamp. The cooling mechanism 1 includes a conveying mechanism 11, which is used to convey coolant so that the coolant can cool the discharge lamp. The conveying mechanism 11 includes an inlet tank 111 and an outlet tank 116. Both the inlet tank 111 and the outlet tank 116 have openings on their side walls. That is, coolant can be poured into the inlet tank 111 through the opening, and the outlet tank 116 is used to store the used coolant and discharge it from the outlet tank 116 through the corresponding opening.

[0049] See Figures 2-5 Multiple control valves 112 are equidistantly installed on the top of the liquid inlet tank 111. The inlet of each control valve 112 extends through a pipe to the bottom wall of the liquid inlet tank 111. The outlet of the control valve 112 is connected to an inlet pipe 113. The end of the inlet pipe 113 away from the corresponding control valve 112 is connected to a spiral cooling pipe 114. The spiral cooling pipe 114 is conical. The end of the spiral cooling pipe 114 away from the inlet pipe 113 is connected to a drain pipe 115. Multiple pump bodies 117 are equidistantly installed on the top of the drain tank 116. The pump bodies 117 are corresponding to the control valves 112. The end of the drain pipe 115 away from the spiral cooling pipe 114 is connected to the inlet of the corresponding pump body 117. The outlet of the pump body 117 is connected to the drain tank 116.

[0050] Pump body 117 is used to draw coolant from inside inlet tank 111. When pump body 117 is started, the corresponding control valve 112 is opened, and pump body 117 draws coolant from inside inlet tank 111. The coolant flows through the pipe on control valve 112 and passes through control valve 112, inlet pipe 113, spiral cooling pipe 114, and drain pipe 115 in sequence to reach the pump body 117. Then, pump body 117 discharges the coolant into drain tank 116 and discharges it from drain tank 116 through the corresponding opening, thereby realizing the flow of coolant.

[0051] The discharge lamp uses a cooling mechanism as described above, including a lamp assembly unit 2. The lamp assembly unit 2 includes a lamp holder 21, a base plate 25 installed at the bottom of the lamp holder 21, and multiple adapter holes 26 equidistantly opened at the bottom of the base plate 25. Each adapter hole 26 is equipped with a lamp body assembly 22. The lamp body assembly 22 is installed in the adapter hole 26 at the bottom of the base plate 25. The lamp body assembly 22 generates heat during use, and the cooling mechanism 1 is used to cool the lamp body assembly 22. That is, the spiral cooling pipe 114 is wound around the outside of the corresponding lamp body assembly 22. When the temperature of the lamp body assembly 22 rises above the threshold, the corresponding pump 117 is activated and controls the coolant to complete one flow of coolant. The coolant flows to the position of the spiral cooling pipe 114, which can carry away the heat on the lamp body assembly 22, thereby achieving the purpose of cooling.

[0052] See Figure 6 The lamp body assembly 22 includes a ceramic lamp holder 223. A lamp cup 221 and a lamp wick 222 are installed at the bottom of the ceramic lamp holder 223. A spiral cooling tube 114 is wound around the lamp cup 221. The lamp wick 222 is located at the center of the lamp cup 221. A temperature sensor 224 is installed on the inner side wall of the lamp cup 221. A state controller module 226 is connected to one side of the ceramic lamp holder 223 by a wire. A status light 225 is connected to the state controller module 226 by a wire. A connector is installed on the outer side wall of the lamp cup 221. The connector is connected to the state controller module 226 by a wire.

[0053] The lamp wick 222 uses a double-layer tube connection, with the electrode wire passing through the inner tube. The lamp wick 222 is a single-layer tube with a larger diameter, which can accommodate thicker wires, resulting in better power and heat dissipation. The status light 225 is protected by a light-transmitting tubular ceramic material. The body of the status light 225 is inside the light-transmitting tubular ceramic protective material, mainly used to indicate whether the lamp wick 222 has been used and whether it is in normal working condition.

[0054] The status light 225 and the status module 226 are placed outside the ceramic lamp holder 223. Before use, the condition of the lamp wick 222 can be checked, and the status can be easily observed. The used lamp wick 222 can be reused by switching the switch of the status module 226 or replacing the internal components of the status module 226. The number of circuit components inside the ceramic lamp holder 223 is reduced, making it easier to process, assemble, and design other functions. The thickness of the four corners of the ceramic lamp holder 223 is different. When the lamp body assembly 22 is assembled, the lamp wick 222 forms a small specific angle with the horizontal line, so that the angle of illumination of multiple lamp body assemblies 22 is different, guiding the light to illuminate at a certain angle and improving the illumination effect.

[0055] The cooling process of lamp body assembly 22 is as follows:

[0056] Each lamp holder 221 is wound with a spiral cooling tube 114, and a temperature sensor 224 is installed on its inner wall. Multiple temperature sensors 224 simultaneously detect the temperature of the corresponding lamp core 222. When the temperature of several lamp cores 222 is too high, the operating temperature of this lamp core 222 has exceeded the threshold. The high temperature of the lamp core 222 will be transferred to the lamp holder 221, and the temperature of the lamp holder 221 will also be very high. At this time, the temperature is controlled by controlling the power of this lamp core 222 to lower the temperature of the lamp core 222. However, although this method controls the temperature of the lamp core 222, the temperature of the lamp core 222 decreases slowly. That is, the lamp core 222 will continue to remain in a state above the operating temperature. Moreover, the lamp holder 221 will also absorb the heat of the lamp core 222 and remain in a high-temperature state. The continuous high temperature of the lamp core 222 and the slow cooling rate of the lamp holder 221 will affect the service life of the lamp body assembly 22.

[0057] Therefore, when the temperature sensor 224 detects that the corresponding lamp wick 222 is at a high temperature, the corresponding pump 117 is started and the coolant is controlled to complete one flow of coolant. The coolant flows to the position of the spiral cooling pipe 114, which can carry away the heat on the lamp cup 221. The lamp cup 221 absorbs the temperature of the lamp wick 222 by heat transfer, thereby reducing the temperature of the lamp wick 222, so that the lamp cup 221 and the lamp wick 222 can be cooled down quickly.

[0058] After one cooling cycle, multiple temperature sensors 224 simultaneously detect the temperature of the corresponding lamp core 222 again. If the temperature is still high, a second cooling operation is performed, while the lamp body assembly 22, which is at normal temperature, does not need to be cooled. This setting, through real-time feedback from the temperature sensors 224, enables precise differentiated control of the lamp core 222. Only the lamp core 222, which is still at a high temperature, is subjected to secondary cooling, while the lamp body assembly 22, which has reached normal temperature, is left untreated. This avoids energy waste and the impact of excessive cooling on component performance, while also reducing manual intervention and improving efficiency.

[0059] After one cooling cycle, coolant accumulates inside the spiral cooling pipe 114, which helps to cool the lamp assembly 22. However, during normal operation, the lamp assembly 22 continues to heat up within its operating temperature range. At the same time, the coolant remaining in the spiral cooling pipe 114 also heats up and absorbs the heat from the lamp assembly 22, slowing down the heating rate of the lamp assembly 22.

[0060] Meanwhile, if the residual coolant accumulates in the spiral cooling pipe 114 for a long time, and the low-temperature coolant is directly injected to cool the lamp body assembly 22 without draining the overheated coolant, the overheated coolant and the low-temperature coolant need to be mixed first. At this time, the temperature of the low-temperature coolant will rise due to the influence of the overheated coolant. This process will consume additional cooling energy, especially in continuous high-frequency cooling scenarios, which may lead to a prolonged second cooling cycle.

[0061] Therefore, an air supply mechanism 12 is installed on the top of the liquid inlet tank 111. When the lamp body assembly 22 needs to be cooled for a second time, the air supply mechanism 12 can discharge the overheated coolant remaining inside the spiral cooling pipe 114 and re-inject low-temperature coolant, thereby reducing the consumption of cooling energy and shortening the cycle of secondary cooling.

[0062] The air supply mechanism 12 includes two frames 121 mounted on the top of the liquid inlet tank 111. Air pipes 122 are mounted on the top of the two frames 121. A pipe body 123 and a drive cylinder 124 are mounted on the top of the liquid inlet tank 111. A piston 125 is connected to the end of the piston rod of the drive cylinder 124. The piston 125 is slidably connected to the inside of the pipe body 123. A first one-way valve 126 and a second one-way valve 127 are connected to the outer wall of the end of the pipe body 123 away from the drive cylinder 124. The end of the second one-way valve 127 is connected to the air pipe 122 via a pipe. Multiple air supply valves 128 are equidistantly mounted on the outer wall of the liquid inlet tank 111. Each air supply valve 128 is correspondingly positioned to correspond to a control valve 112. The end of each air supply valve 128 away from the air pipe 122 is connected to the corresponding liquid inlet pipe 123. The outer walls of tube 123 are connected. The flow direction of the first one-way valve 126 is from the outside to the inside of tube 123, and the flow direction of the second one-way valve 127 is from the inside of tube 123 to the inside of air pipe 122. When the piston rod of the drive cylinder 124 gradually contracts, the piston 125 slides towards the opening of tube 123, and the space between tube 123 and piston 125 increases. At this time, external air will enter the inside of tube 123 through the first one-way valve 126. When the piston rod of the drive cylinder 124 gradually extends, the piston 125 slides towards the inside of tube 123, and the space between tube 123 and piston 125 decreases. At this time, the air inside tube 123 will be pushed into air pipe 122 and accumulate through the second one-way valve 127 and the matching pipe.

[0063] Specifically, after the lamp assembly 22 completes one cooling cycle, the temperature sensor 224 detects the temperature of the lamp assembly 22. If the temperature of the lamp assembly 22 is still above the operating temperature threshold, the corresponding air supply valve 128 opens. Then, the drive cylinder 124 pushes the piston 125 to slide into the tube 123. The air inside the tube 123 is pushed into the air pipe 122 through the second one-way valve 127 and the corresponding pipe, and the air entering the air pipe 122 enters the corresponding liquid inlet pipe 113 through the open air supply valve 128. The air flows inside the liquid inlet pipe 113 and cools the remaining overheat. When the liquid is squeezed, the corresponding pump body 117 opens. Under the combined action of the pump body 117 and the flowing air, the superheated air is squeezed out into the spiral cooling pipe 114 and the drain pipe 115. The superheated liquid is discharged into the drain tank 116 through the pump body 117. After the superheated coolant is discharged, the air supply valve 128 is closed, and the pump body 117 can re-draw the coolant into the liquid tank 111. At this time, the piston rod of the drive cylinder 124 gradually retracts, and the piston 125 slides towards the opening of the pipe body 123. The space between the pipe body 123 and the piston 125 increases, and external air will enter the pipe body 123 through the first one-way valve 126 for later use.

[0064] By monitoring the temperature sensor 224 and linking the air supply valve 128 with the drive cylinder 124, when the temperature of the lamp assembly 22 still exceeds the threshold after cooling, the residual overheated coolant in the liquid inlet pipe 113 is squeezed by air, and the overheated liquid is discharged with the help of the pump body 117. Then, low-temperature coolant is re-injected, which avoids temperature fluctuations caused by residual coolant, reduces the consumption of cooling energy, and shortens the cycle of secondary cooling.

[0065] In the second embodiment, the four corners of the lamp cup 221 have different thicknesses, so that after the lamp cup 221 is assembled, the lamp wick 222 forms a small specific angle with the horizontal line. However, this method is only applicable to specific equipment or specific lamp holders. The required angles are not the same for different manufacturers, different series of equipment, or even different working conditions.

[0066] Furthermore, if a specific lamp holder is used, when one of the lamps is removed and replaced with a new one during maintenance, the placement angle of the lamp cup 221 needs to be readjusted. It is easy to misplace the parts with inconsistent thickness on the lamp cup 221, and the assembly angle of the lamp cup 221 will be deviated, thus affecting the installation stability.

[0067] For this purpose, please refer to Figure 5 and Figure 7 An assembly component 23 is installed inside each adapter hole 26, and a lamp body assembly 22 is provided on the top of each assembly component 23. The assembly component 23 is used for assembly and adjustment of the corresponding lamp body assembly 22. The specific structure of the assembly component 23 is as follows:

[0068] See Figure 10 and Figure 11 Each assembly component 23 includes a first ring 231 rotatably connected inside the corresponding adapter hole 26. A second ring 232 is provided above the first ring 231. Four pressure rods 235 are vertically arranged at equal intervals on the top of the second ring 232. The bottom of each pressure rod 235 passes through the corresponding second ring 232. A support seat 233 is installed on the top of each pressure rod 235. A spring 234 is connected between the support seat 233 and the second ring 232. The spring 234 is sleeved on the outer wall of the corresponding pressure rod 235. When the lamp body assembly 22 needs to be assembled, the operator only needs to place the lamp cup 221 diagonally on the top of the four support seats 233. The four support seats 233 cooperate to position the lamp cup 221.

[0069] See Figure 11 An L-shaped tube 238 is fitted onto the outer wall of the upright 236. A Y-shaped frame 237 is horizontally connected to the end of the L-shaped tube 238 furthest from the upright 236. The Y-shaped frame 237 is fitted onto the outer wall of the corresponding lamp holder 221. The L-shaped tube 238 slides on the outer wall of the upright 236, causing the Y-shaped frame 237 to move synchronously. After the lamp holder 221 is positioned, the Y-shaped frame 237 presses against the outside of the corresponding lamp holder 221. At this time, due to the different thicknesses at the four corners of the lamp holder 221, the lamp holder 221... The four corners of the lamp cup 221 are pressed down on the corresponding pressure rods 235 and squeezed by the springs 234. The four sets of pressure rods 235 and springs 234 cooperate to compensate the four corners of the lamp cup 221. The springs 234 use the reaction force to push the support seat 233 upward and push the lamp cup 221 upward. That is, the support seat 233 and the Y-shaped frame 237 cooperate to complete the assembly and clamping of the lamp cup 221. This assembly method does not need to consider the different thicknesses of the dead corners of the lamp cup 221 and can directly complete the assembly operation.

[0070] In Example 3, since the angle of the lamp is limited, the illumination range is small. Currently, in order to increase the illumination range of the lamp, an electric adjustment mechanism can be used, that is, an adjustment mechanism is set on each lamp to adjust the illumination angle of a single lamp according to different needs. However, the internal space of the lamp holder 21 is insufficient, and the electric adjustment mechanism will occupy the placement space of the lamp body assembly 22. Since the lamp body assembly 22 also includes structures such as status lamp 225 and wires, the electric adjustment mechanism is easy to interfere with the lamp body assembly 22. Moreover, since it occupies the placement space, it will also affect the active heat dissipation effect of the lamp body assembly 22.

[0071] Therefore, a vertical rod 236 and a lead screw 239 are provided at the top of the first ring body 231. The vertical rod 236 and the lead screw 239 are arranged opposite to each other. The bottom of the vertical rod 236 is connected to the first ring body 231, and the bottom of the lead screw 239 passes through the first ring body 231. Two hinge mechanisms 2301 are symmetrically hinged to the outer wall of the second ring body 232. The two hinge mechanisms 2301 are respectively arranged corresponding to the vertical rod 236 and the lead screw 239. One hinge mechanism 2301 is connected to the vertical rod 236, and the other hinge mechanism 2301 is threadedly connected to the lead screw 239. The second ring body 232 is assembled with the lamp body assembly 22 as a whole. The vertical rod 236 is connected to the lamp body assembly 22. 6. The second ring body 232 is hinged to the corresponding hinge mechanism 2301, so that the second ring body 232 can maintain a fixed height at one position. The hinge mechanism 2301 on the outer wall of the lead screw 239 is threadedly connected to the lead screw 239. Therefore, when the lead screw 239 rotates, the corresponding hinge mechanism 2301 can move up and down. This hinge mechanism 2301 can pull the second ring body 232 to move up and down. At this time, the second ring body 232 can switch between tilted upward, horizontal and tilted downward states through the hinge mechanism 2301 corresponding to the upright 236, thereby adjusting the illumination range of the lamp assembly 22.

[0072] Furthermore, since the first ring 231 can rotate inside the corresponding adapter hole 26, the adjustable illumination range of the lamp assembly 22 is further increased.

[0073] See Figure 5 , Figures 7-9 The bottom of the lamp holder 21 is provided with an adjustment component 24, which is used to adjust each assembly component 23, that is, to adjust the rotational position of the first ring 231 and the tilt angle of the second ring 232. The specific structure of the adjustment component 24 is as follows:

[0074] See Figures 7-9 The adjustment component 24 includes two sets of guide rails 241 symmetrically installed at the bottom of the lamp holder 21. Each guide rail 241 has an electric slider 242 slidably connected to its bottom. Each electric slider 242 has a bracket 243 installed at its bottom. A rotating shaft 244 is rotatably connected between the two brackets 243. The two electric sliders 242 move synchronously on the corresponding guide rails 241, thereby enabling the corresponding brackets 243 and the rotating shaft 244 to move synchronously. A fixing plate 246 is installed on the outer wall of the rotating shaft 244. A drive motor 245 is installed on one side of one of the brackets 243. The output end of the drive motor 245 is connected to one end of the rotating shaft 244. The drive motor 245 is used to drive the rotating shaft 244 to rotate, thereby adjusting the angle and side orientation of the fixing plate 246.

[0075] See Figures 7-9An electric slide rail 247 is mounted on the side wall of the fixed plate 246. A slide table 248 is slidably connected to the side wall of the electric slide rail 247. The electric slide rail 247 can be a stepper motor linear slide rail slide block module, which is not specifically limited here. The slide block of the electric slide rail 247 is connected to the slide table 248. When the electric slide rail 247 drives the slide block to move, the slide table 248 can move synchronously. A moving platform 249 is slidably connected to the side wall of the slide table 248. A telescopic cylinder 2403 is mounted on the side wall of the slide table 248. The piston rod of the telescopic cylinder 2403 is connected to the moving platform 249. When the side of the fixed plate 246 where the electric slide rail 247 is mounted swings to the upward position, the telescopic cylinder 2403 can push the moving platform 249 to move up and down at the side wall position of the slide table 248 to adjust the height. An assembly motor 2401 is mounted on the side of the moving platform 249 near the slide table 248. The output end of the assembly motor 2401 passes through the moving platform 248. 9. A rotating plate 2404 is connected to the rotating plate 2404. A rotary motor 2405 is installed on the side of the rotating plate 2404 near the moving platform 249. The output end of the rotary motor 2405 passes through the rotating plate 2404 and is connected to the electric clamp 2402. When the side of the fixed plate 246 with the electric slide rail 247 is swung to the upward position, the assembly motor 2401 is in the vertical upward position. When the moving platform 249 is raised and lowered, it can drive the assembly motor 2401, the rotating plate 2404, the rotary motor 2405 and the electric clamp 2402 to move synchronously. The assembly motor 2401 is used to drive the rotating plate 2404 to rotate, thereby adjusting the position of the rotary motor 2405 and the electric clamp 2402. The rotary motor 2405 is used to drive the electric clamp 2402 to rotate, and the electric clamp 2402 is used to clamp and rotate the lead screw 239 that needs to be rotated, thereby adjusting the illumination angle of the second ring 232 and the lamp assembly 22.

[0076] Specifically, since the adjustment component 24 is located on the side of the lamp holder 21, when the adjustment component 24 is in its initial state, the electric slider 242 drives the bracket 243 and the various components installed on the bracket 243 to move to the side of the lamp holder 21. Then the fixing plate 246 swings to the vertical state. At this time, the adjustment component 24 does not block the illumination of each lamp body component 22, reducing the space occupied above the lamp body component 22.

[0077] When it is necessary to adjust the illumination angle of one of the lamp components 22, the drive motor 245 first drives the rotating shaft 244 to rotate. The rotating shaft 244 drives the fixing plate 246 to adjust the angle. When the side of the fixing plate 246 with the electric slide rail 247 is swung to the upward position, the electric slider 242 drives the bracket 243 and other components to move synchronously. At the same time, the electric slide rail 247 drives the slide table 248, the moving table 249 and the electric clamp 2402 to move synchronously, thereby enabling the electric clamp 2402 to move to the lamp body that needs to be adjusted. Below component 22, the assembly motor 2401 drives the rotating plate 2404 to rotate, thereby adjusting the position of the electric clamp 2402 so that the electric clamp 2402 is below the corresponding lead screw 239. The telescopic cylinder 2403 can push the moving table 249 to move up and down on the side wall of the slide table 248 to adjust the height. While the moving table 249 is rising and falling, it can drive the assembly motor 2401, the rotating plate 2404 and the electric clamp 2402 to move synchronously, so that the electric clamp 2402 can clamp the lead screw 239.

[0078] When the lamp assembly 22 requires angle and orientation adjustment, the assembly motor 2401 drives the rotating plate 2404 to rotate, which in turn causes the electric clamp 2402 to rotate around the output end of the assembly motor 2401. At this time, the electric clamp 2402 drives the lead screw 239 to move. When the lead screw 239 moves, it drives the first ring body 231 to rotate, thereby adjusting the orientation of the lamp assembly 22. After the orientation adjustment is completed, the rotary motor 2405 drives the electric clamp 2402 to rotate. The electric clamp 2402 clamps and rotates the lead screw 239, thereby adjusting the illumination angle of the second ring body 232 and the lamp assembly 22, increasing the illumination range of the lamp assembly 22.
