Description

Technical Field

[0001] This invention relates to the field of iodine-tungsten lamp life testing technology, specifically to an iodine-tungsten lamp filament life testing device. Background Technology

[0002] Iodine-tungsten lamps are a typical type of halogen tungsten lamps. Their working principle is to use tungsten filaments to emit light at high temperatures, while simultaneously using halogen gases such as iodine to form a "halogen tungsten cycle," which redeposits the evaporated tungsten onto the filament, thereby extending the filament's lifespan and keeping the bulb's inner wall clean. Iodine-tungsten lamps need to undergo lifespan testing before leaving the factory.

[0003] Using on / off switching for life testing is a common method. By repeatedly turning the tungsten iodine lamp on and off, the frequent start-stop conditions during actual use are simulated, thereby accelerating the thermal shock and material fatigue process of the filament and assessing its lifespan more quickly. Usually, after each power-off, the lamp tube needs to be allowed to cool down to a certain temperature naturally before the next power-on operation can be performed. However, since the tungsten iodine lamp has a high temperature during operation and its heat dissipation mainly relies on natural cooling, the cooling process takes a long time, extending the testing cycle and resulting in low testing efficiency. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of low efficiency in the detection of iodine-tungsten lamp life in the prior art, and to propose an iodine-tungsten lamp filament life detection device.

[0005] To solve the above problems, the present invention provides the following technical solution: A workbench is included, on which a testing platform is mounted. A power-on device is slidably mounted on the testing platform, and a heat dissipation device is mounted on one side of the power-on device. The power-on device is connected to a control system. In use, the lamp to be tested is combined with its holder and placed into the heat dissipation device. The power-on device is then lowered to illuminate the lamp. After a predetermined time, the power-on device is raised to extinguish the lamp. After another predetermined time, the lamp is illuminated again. This process is repeated until a predetermined number of cycles are completed, at which point the tested lamp is removed.

[0006] The heat dissipation device includes a housing and a cooling assembly. The housing is mounted on the testing platform and has heat dissipation vents. A drive unit is mounted on the outside of the housing, and a placement seat is installed inside the housing. A power-on socket is mounted on the placement seat, and a locking assembly is mounted on one side of the placement seat. An adjustment assembly is mounted on the other side of the locking assembly. The drive unit is connected to the control system. In use, the lamp to be tested is placed into the placement seat after being combined with the lamp holder. The control unit lowers to the power-on socket, connects the circuit, and lights up the lamp. The high temperature around the lit lamp and lamp holder creates a slight negative pressure, drawing in external gas through the heat dissipation vents and expelling it through the adjustment assembly.

[0007] The cooling assembly includes a U-shaped plate mounted on a mounting base. An air guide plate is installed on one side of the U-shaped plate, and one end of the air guide plate is mounted on a locking assembly. A switching element is slidably installed inside the U-shaped plate. When the lamp is lit, the airflow entering the mounting housing flows from both sides of the U-shaped plate, preventing external airflow from directly entering the high-temperature area of ​​the lamp. This prevents uneven heating or even damage to the lamp due to uneven cooling or airflow impact, ensuring the lamp operates in a stable thermal environment. When the lamp is off, a servo motor controls the switching element to move, directing airflow through the lamp holder after heating before flowing from the U-shaped plate into the lamp area, placing the lamp in a relatively mild cooling environment and accelerating heat dissipation.

[0008] The locking assembly includes a heat transfer element mounted on the outside of the placement base. A rotating element is mounted on one side of the heat transfer element, and a protective plate is mounted on the other side of the rotating element. The protective plate rotates on the placement housing. After the lamp tube and lamp holder to be tested are manually placed into the placement base, the protective plate is returned to its initial position. During the test, due to the high temperature of the lamp holder, the heat transfer element drives the rotating element to lock the protective plate, preventing it from opening during the test. After the test is completed, when the temperature of the lamp holder drops to a predetermined value, the heat transfer element drives the rotating element to unlock the protective plate, allowing the lamp tube and lamp holder to be removed.

[0009] The U-shaped plate includes an isolation plate with a first air inlet slot. A guide plate is installed on one side of the isolation plate, and a first air inlet slot is also provided on the guide plate. The first air inlet slot is connected to the first air intake slot, and a guide rail is installed on the first air intake slot. A switching element slides on the guide rail, and the guide plate is installed on the guide plate. When the lamp is lit, external airflow enters the housing through the heat dissipation vent, flows through the guide plate and the isolation plate, and exits through the regulating component. At this time, the switching element blocks the first air intake slot, isolating the lamp area and preventing external air from entering. When the lamp is turned off, the switching element moves, allowing external air to pass through the guide plate and enter the first air intake slot. The heated air then enters the lamp area from the first air intake slot, gently cooling the lamp.

[0010] The air guide plate includes an arc-shaped block with a second air inlet slot connected to the first air inlet slot. An air inlet is located at the bottom of the arc-shaped block, and an air outlet is located on one side. When the lamp is lit, outside air enters through the air inlet. Because the first air inlet slot is blocked by the switching element, the outside air expels the heat from the lamp holder through the air outlet. When the lamp is turned off, outside air enters through the air inlet. Since the temperature in the lamp area is higher than that in the lamp holder area, the air entering the arc-shaped block is heated and then drawn into the first air inlet slot, entering the lamp area from there.

[0011] The switching element includes a switching plate that slides within a guide rail. A second air intake slot is provided on the switching plate. An elastic element is installed on one side of the switching plate, with one end of the elastic element mounted on a guide plate. A protrusion is installed on the other side of the switching plate, and a cam is installed on one side of the protrusion. The cam abuts against the protrusion, and a first rotating shaft is installed on the cam. The first rotating shaft rotates within the housing, and a transmission element is installed between the first rotating shaft and the driving element. The transmission components include a third transmission belt mounted on a first rotating shaft. The other end of the third transmission belt is also mounted on a third rotating shaft, on which a first bevel gear is mounted. A second bevel gear is mounted on a servo motor. The first and second bevel gears mesh. When the lamp is lit, the servo motor is activated, driving the second bevel gear to rotate. The second bevel gear then drives the first bevel gear to rotate, which in turn drives the third rotating shaft to rotate. The third rotating shaft then drives the third transmission belt to rotate, which in turn drives the first rotating shaft to rotate. The first rotating shaft then drives the cam to rotate. At this point, the cam rotates until its flange contacts the cam block. The flange drives the cam block to move closer to the protective door. The cam block drives the switching plate to move closer to the protective door along the guide rail. The second air intake slot is offset from the first air intake slot, and the switching plate blocks the first air intake slot. When the lamp is extinguished, the servo motor is reversed. At this point, the base circle of the cam contacts the cam block, and the spring stretches, causing the guide plate to move further away from the protective door along the guide rail. The second air intake slot aligns with the first air intake slot.

[0012] The heat transfer element includes a heat-conducting sleeve mounted on the outside of the mounting base. A capillary heat pipe is installed on one side of the heat-conducting sleeve, and the capillary heat pipe is filled with a cooling medium. Another side of the capillary heat pipe is mounted on a rotating element. The heat-conducting sleeve conducts heat from the lamp holder area to the evaporation end of the capillary heat pipe. The cooling medium at the evaporation end absorbs heat and evaporates, while the gaseous medium liquefies and releases heat at the condensation end. The liquid medium flows back from the capillary heat pipe to the evaporation end.

[0013] The rotating element includes an insulated box mounted on the inner wall of the housing. Inside the insulated box is a connecting block, within which a long rod is rotatably mounted. A bimetallic strip is sleeved on the outer side of the long rod, with one end of the bimetallic strip mounted on the connecting block and the other end on the long rod. An extension rod is attached to one end of the long rod, and a pin plate is mounted on one side of the extension rod. When the bimetallic strip senses heat from the condenser end of the capillary heat pipe, it twists, causing the long rod to rotate. The long rod then rotates the extension rod, which in turn rotates the pin plate.

[0014] The protective plate includes a protective door that rotates on the housing. A latch and a pin seat are installed on one side of the protective door, and a latch seat is installed on the inner wall of the housing. The latch and latch seat are compatible. When the lamp tube and lamp holder to be tested are placed in, the protective door is returned to its initial position, and the latch engages with the latch seat. When testing begins, the pin plate rotates and inserts into the pin seat, locking the protective door.

[0015] The adjustment assembly includes a mounting base mounted on the housing. A second rotating shaft is rotatably mounted within the mounting base, and a baffle is mounted on the second rotating shaft. A first drive wheel and a second drive wheel are mounted at one end of the second rotating shaft. A first drive belt is mounted on the first drive wheel, and a second drive belt is mounted on the second drive wheel. One end of the second drive belt is mounted on a drive component. When testing begins, a servo motor is controlled to rotate, which drives the second drive belt to rotate. The second drive belt then drives the second drive wheel to rotate, which in turn drives the second rotating shaft to rotate. The second rotating shaft then drives the first drive wheel and the baffle to rotate, and the first drive wheel drives the first drive belt to rotate. The baffle rotates to a certain angle to reduce backflow of external airflow. When the test ends, the servo motor is controlled to reverse, causing the baffle to rotate back to 90 degrees, allowing heat from the lamp holder to dissipate more quickly.

[0016] The driving components include servo motors, and the elastic components include springs.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention employs waste heat dissipation technology. During the lamp's operation, a passive heat dissipation method is used, guiding and isolating the airflow around the lamp through a flow-guiding structure. This prevents external airflow from directly entering the high-temperature area of ​​the lamp, thus preventing uneven heating or even damage to the lamp and ensuring that the lamp operates in a stable thermal environment. During the lamp's de-energization, the waste heat accumulated in the lamp holder is used to heat the surrounding air, and the heated air is slowly introduced into the lamp area, placing the lamp in a relatively mild cooling environment. This avoids the sudden cooling phenomenon caused by cold air directly contacting the high-temperature lamp, reducing the risk of lamp breakage due to sudden changes in thermal stress. At the same time, under controlled conditions, the overall heat dissipation process of the lamp is accelerated, shortening the cooling time between each on / off cycle and reducing the testing cycle.

[0029] The embodiments of the present invention will now be further described in conjunction with the accompanying drawings and examples.

[0030] Example: Figures 1-9 As shown, the present invention provides a technical solution including a workbench, a testing platform 2 mounted on the workbench, a power supply device 3 slidably mounted on the testing platform 2, a heat dissipation device 1 mounted on one side of the power supply device 3, and the power supply device 3 connected to a control system; in use, the lamp to be tested is combined with the lamp holder and placed into the heat dissipation device 1, the power supply device 3 is controlled to descend to light up the lamp, after a predetermined time, the power supply device 3 is controlled to rise to extinguish the lamp, after a predetermined time, the lamp is lit up again, and the above steps are repeated. When the cycle is repeated a predetermined number of times, the lamp after the test is completed is taken out.

[0031] The heat dissipation device 1 includes a housing 11 and a cooling component 12. The housing 11 is mounted on the testing platform 2 and has a heat dissipation vent. A drive component 16 is mounted on the outside of the housing 11, and a placement seat 13 is mounted inside the housing 11. A power supply seat is mounted on the placement seat 13. A locking component 14 is mounted on one side of the placement seat 13, and an adjustment component 15 is mounted on one side of the locking component 14. The drive component 16 is connected to the control system. The drive component 16 includes a servo motor. In use, the lamp tube to be tested is combined with the lamp holder and placed into the placement seat 13. The power supply device 3 is controlled to descend onto the power supply seat, connect the circuit, and light up the lamp tube. The temperature around the lit lamp tube and lamp holder is high, forming a slight negative pressure, which draws in external gas from the heat dissipation vent and discharges it from the adjustment component 15.

[0032] The cooling assembly 12 includes a U-shaped plate 121, which is mounted on the placement base 13. A guide plate 122 is installed on one side of the U-shaped plate 121, and one end of the guide plate 122 is mounted on the locking assembly 14. A switching element 123 is slidably installed inside the U-shaped plate 121. When the lamp is lit, the airflow entering the placement housing 11 flows from both sides of the U-shaped plate 121, preventing external airflow from directly entering the high-temperature area of ​​the lamp. This prevents uneven heating or even damage to the lamp due to uneven local cooling or airflow impact, ensuring that the lamp operates in a stable thermal environment. When the lamp is turned off, the switching element 123 is moved by a servo motor, causing the airflow to flow from the U-shaped plate 121 into the lamp area after being heated by the lamp holder. This places the lamp in a relatively mild cooling environment, accelerating heat dissipation.

[0033] The locking assembly 14 includes a heat transfer element 141, which is mounted on the outside of the placement base 13. A rotating element 142 is mounted on one side of the heat transfer element 141, and a protective plate 143 is mounted on one side of the rotating element 142. The protective plate 143 rotates on the placement housing 11. After the lamp tube and lamp holder to be tested are manually placed into the placement base 13, the protective plate 143 is returned to its initial position. During the test, due to the high temperature of the lamp holder, the heat transfer element 141 drives the rotating element 142 to lock the protective plate 143, preventing it from opening during the test. After the test is completed, when the temperature of the lamp holder drops to a predetermined value, the heat transfer element 141 drives the rotating element 142 to unlock the protective plate 143, allowing the lamp tube and lamp holder to be removed.

[0034] The U-shaped plate 121 includes an isolation plate 1211, on which a first air inlet groove 1213 is provided. A guide plate 1212 is installed on one side of the isolation plate 1211. A first air inlet groove is provided on the guide plate 1212. The first air inlet groove is connected to the first air inlet groove 1213. A guide rail 1214 is installed on the first air inlet groove. A switching element 123 slides on the guide rail 1214. A guide plate 122 is installed on the guide plate 1212. When the lamp is lit, external airflow enters the housing 11 through the heat dissipation vent, flows through the baffle plate 1212 and the isolation plate 1211, and exits through the regulating component 15. At this time, the switching element 123 blocks the first air inlet slot 1213, isolating the lamp area and preventing external air from entering the lamp area. When the lamp is turned off, the switching element 123 moves, allowing external air to enter the first air inlet slot through the baffle plate 122. The heated air then enters the first air inlet slot 1213 from the first air inlet slot 1213 and enters the lamp area to gently cool the lamp.

[0035] The air guide plate 122 includes an arc-shaped block 1221, on which a second air inlet groove 1224 is provided. The second air inlet groove 1224 is connected to the first air inlet groove. An air inlet 1222 is provided at the bottom of the arc-shaped block 1221, and an air outlet 1223 is provided on one side of the arc-shaped block 1221. When the lamp is lit, outside air enters through the air inlet 1222. Since the first air inlet groove 1213 is blocked by the switching element 123, the outside air exhausts the heat of the lamp holder through the air outlet 1223. When the lamp is turned off, outside air enters through the air inlet 1222. Since the temperature of the lamp area is higher than that of the lamp holder area, the gas entering the arc-shaped block 1221 is heated and then drawn into the first air inlet groove, and enters the lamp area from the first air inlet groove 1213.

[0036] The switching element 123 includes a switching plate 1231, which slides within a guide rail 1214. A second air intake groove 1232 is provided on the switching plate 1231. An elastic element 1235 is installed on one side of the switching plate 1231, with one end of the elastic element 1235 mounted on a guide plate 1212. A protrusion 1234 is installed on the other side of the switching plate 1231, and a cam 1236 is installed on one side of the protrusion 1234. The cam 1236 abuts against the protrusion 1234. A first rotating shaft 1233 is installed on the cam 1236. The first rotating shaft 1233 rotates within the housing 11. A transmission element is installed between the first rotating shaft 1233 and the driving element 16. The elastic element 1235 includes a spring, and the transmission element includes a third transmission belt. The third transmission belt is mounted on the first rotating shaft 1233, and the other end of the third transmission belt is mounted on the third rotating shaft. A first bevel gear is mounted on the third rotating shaft, and a second bevel gear is mounted on the servo motor. The first and second bevel gears mesh. When the lamp is lit, the servo motor is started, driving the second bevel gear to rotate. The second bevel gear drives the first bevel gear to rotate, which in turn drives the third rotating shaft to rotate. The third rotating shaft drives the third transmission belt to rotate, which in turn drives the first rotating shaft 1233 to rotate. The first rotating shaft 1233 then drives the cam 1236 to rotate. At this time, the cam 1236... Rotate until the flange contacts the protrusion 1234. The flange drives the protrusion 1234 to move closer to the protective door 1431. The protrusion 1234 drives the switching plate 1231 to move closer to the protective door 1431 on the guide rail 1214. The second air intake groove 1232 is offset from the first air intake groove 1213. The switching plate 1231 blocks the first air intake groove 1213. When the lamp is turned off, control the servo motor to reverse. At this time, the base circle of the cam 1236 contacts the protrusion 1234. The spring is stretched and drives the guide plate 1212 to move away from the protective door 1431 on the guide rail 1214. The second air intake groove 1232 is aligned with the first air intake groove 1213.

[0037] The heat transfer element 141 includes a heat-conducting sleeve 1411, which is mounted on the outside of the mounting base 13. A capillary heat pipe 1412 is mounted on one side of the heat-conducting sleeve 1411, and the capillary heat pipe 1412 is filled with a cooling medium. One side of the capillary heat pipe 1412 is mounted on the rotating element 142. The heat-conducting sleeve 1411 conducts heat from the lamp holder area to the evaporation end of the capillary heat pipe 1412. The cooling medium at the evaporation end absorbs heat and evaporates, while the gaseous medium liquefies and releases heat at the condensation end. The liquid medium flows back from the capillary tube to the evaporation end of the capillary heat pipe 1412.

[0038] The rotating element 142 includes a heat insulation box 1421, which is installed on the inner wall of the housing 11. A connecting block 1422 is installed inside the heat insulation box 1421. A long rod 1423 is rotatably mounted inside the connecting block 1422. A bimetallic strip 1424 is sleeved on the outer side of the long rod 1423. One end of the bimetallic strip 1424 is mounted on the connecting block 1422, and the other end is mounted on the long rod 1423. An extension rod 1425 is mounted on one end of the long rod 1423, and a pin plate 1426 is mounted on one side of the extension rod 1425. When the bimetallic strip 1424 senses heat from the condenser end of the capillary heat pipe 1412, the bimetallic strip 1424 twists, causing the long rod 1423 to rotate. The long rod 1423 then drives the extension rod 1425 to rotate, and the extension rod 1425 drives the pin plate 1426 to rotate.

[0039] The protection plate 143 includes a protection door 1431, which rotates on the housing 11. A latch and a pin seat 1432 are installed on one side of the protection door 1431. A latch seat is installed on the inner wall of the housing 11, and the latch and latch seat are compatible. When the lamp tube and lamp holder to be tested are placed in, the protection door 1431 is returned to its initial position, and the latch engages with the latch seat. When testing begins, the pin plate 1426 rotates and inserts into the pin seat 1432, locking the protection door 1431.

[0040] The adjustment assembly 15 includes a mounting base 151, which is mounted on the housing 11. A second rotating shaft 152 is rotatably mounted inside the mounting base 151. A wind deflector 153 is mounted on the second rotating shaft 152. A first transmission wheel and a second transmission wheel are mounted on one end of the second rotating shaft 152. A first transmission belt 154 is mounted on the first transmission wheel, and a second transmission belt 155 is mounted on the second transmission wheel. One end of the second transmission belt 155 is mounted on the drive component 16. When the lamp is lit, the servo motor is controlled to rotate, which drives the second transmission belt 155 to rotate. The second transmission belt 155 drives the second transmission wheel to rotate, which drives the second rotating shaft 152 to rotate. The second rotating shaft 152 drives the first transmission wheel and the wind deflector 153 to rotate, and the first transmission wheel drives the first transmission belt 154 to rotate. The wind deflector 153 rotates to 45° to reduce backflow of external airflow. When the lamp is turned off or the test is over, the servo motor is controlled to reverse, causing the wind deflector 153 to rotate back to 90°, allowing the heat from the lamp holder to dissipate more quickly.

[0041] Working principle of the invention:

[0042] In use, the protective door 1431 is manually opened, and the lamp tube and lamp holder to be tested are placed into the placement seat 13. Then, the protective door 1431 is returned to its initial position, and the latch is engaged in the latch seat. The servo motor is controlled to rotate, which drives the second transmission belt 155 to rotate. The second transmission belt 155 drives the second transmission wheel to rotate, which drives the second rotating shaft 152 to rotate. The second rotating shaft 152 drives the first transmission wheel and the wind deflector 153 to rotate. The first transmission wheel drives the first transmission belt 154 to rotate, and the wind deflector 153 rotates to 45° to reduce the backflow of external airflow. At the same time, the servo motor drives the second bevel gear to rotate. The gear drives the first bevel gear to rotate, the first bevel gear drives the third shaft to rotate, the third shaft drives the third transmission belt to rotate, the third transmission belt drives the first shaft 1233 to rotate, the first shaft 1233 drives the cam 1236 to rotate. At this time, the cam 1236 rotates until the flange contacts the protrusion 1234. The flange drives the protrusion 1234 to move towards the protective door 1431. The protrusion 1234 drives the switching plate 1231 to move towards the protective door 1431 on the guide rail 1214. The second air inlet groove 1232 is offset from the first air inlet groove 1213, and the switching plate 1231 blocks the first air inlet groove 1213.

[0043] The control power-on device 3 descends onto the power-on base, connects the circuit, and lights up the lamp. Due to the high temperature around the lit lamp and lamp holder, a slight negative pressure is formed, drawing in external gas from the heat dissipation vent and discharging it from the wind deflector 153. The gas inside the housing 11 flows through the guide plate 1212 and the isolation plate 1211, and is discharged from the adjustment component 15. At this time, the switching element 123 blocks the first air inlet slot 1213, isolating the lamp area and preventing external gas from entering the lamp area. External air enters from the lamp holder through the air inlet 1222. Since the first air inlet slot 1213 is blocked by the switching element 123, the external air dissipates the heat of the lamp holder from the air outlet 1223.

[0044] After the lamp is lit for the predetermined time, the control power-on device 3 rises to extinguish the lamp and the control servo motor reverses. At this time, the wind deflector 153 rotates back 90°, the base circle of the cam 1236 contacts the protrusion 1234, and the spring stretches to drive the guide plate 1212 to move away from the protection door 1431 on the guide rail 1214. The second air inlet slot 1232 is aligned with the first air inlet slot 1213, and outside air enters from the air inlet 1222. Since the temperature of the lamp tube area is higher than that of the lamp holder area, the gas entering the arc block 1221 is heated and then sucked into the first air inlet slot, and enters the lamp tube area from the first air inlet slot 1213 to gently cool the lamp tube.

[0045] During the testing process, the heat-conducting sleeve 1411 conducts heat from the lamp holder area to the evaporation end of the capillary heat pipe 1412. The cooling working fluid at the evaporation end absorbs heat and evaporates, while the gaseous working fluid liquefies and releases heat at the condensation end. The liquid working fluid flows back from the capillary tube to the evaporation end of the capillary heat pipe 1412. The bimetallic strip 1424 senses the heat at the condensation end of the capillary heat pipe 1412 and twists, causing the long rod 1423 to rotate. The long rod 1423 then causes the extension rod 1425 to rotate, which in turn causes the pin plate 1426 to rotate. The pin plate 1426 rotates and inserts into the pin seat 1432, locking the protection door 1431. When the testing is completed, the temperature of the lamp holder drops to the predetermined value, and the bimetallic strip 1424 resets until the pin plate 1426 rotates away from the pin seat 1432, unlocking the protection door 1431. The protection door 1431 is then manually opened, and the lamp and lamp holder after the testing are removed from the placement seat 13.
