Description

Technical Field

[0001] This invention relates to the field of light strip testing equipment, specifically a testing device for testing the energy efficiency and waterproofness of OLED lighting strips. Background Technology

[0002] With the development of technology, there are many types of lighting equipment, including OLED lighting strips.

[0003] Currently, flexible LED strips are widely used in automotive trim, signs, advertising signs, wine cabinets, jewelry cabinets, entertainment venues, pathways, and outline markings due to their flexibility, customizable shapes, and ease of installation. Since LED strips are sometimes installed in indoor or outdoor environments, they are susceptible to rain and even water immersion in rainy weather. Therefore, LED strips need to be tested before leaving the factory to improve the pass rate.

[0004] After the light strips are manufactured, they need to undergo several tests, the most important of which is the waterproof test.

[0005] Current problems with waterproof testing and switch fatigue testing include: 1. During waterproof testing, the lamps cannot be fixed in place and roll due to the impact of pressurized water, causing them to loosen. 2. During switch fatigue testing, the lamps are not clamped tightly and swing from side to side, resulting in displacement. This displacement leads to inaccurate spray coverage. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a testing device for evaluating the energy efficiency and waterproofness of OLED lighting strips, thus solving the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: a test device for testing the energy saving and waterproof properties of OLED lighting strips, which tests the strip body. A switch is fixedly installed on the left end of the strip body. The device includes a test slot, a crossbar is provided in the test slot, and shower heads are arranged at equal intervals on the crossbar. The strip body is placed on the crossbar, and multiple slide rails are provided at the bottom of the crossbar. The slide rails are connected to positioning components, which are used to fix the strip body.

[0008] The positioning assembly includes a slide rod, a positioning rod, and a vertical rod. The slide rod body slides in conjunction with the slide rail, and the end of the slide rod bends upward through the slide rail. The positioning rod is located above the horizontal bar, and the end of the positioning rod bends downward and is inserted into the end of the slide rod. The bottom of the slide rod is connected to the vertical rod, which extends vertically downward to the outside of the slide rail. A driving part is connected to the outside of the test groove, and the driving part is connected to the vertical rod. The driving part drives the slide rod to descend, so that the positioning rod is locked on the horizontal bar, and the light strip body is clamped by the horizontal bar and the positioning rod.

[0009] A power flow meter is installed on the outside of the test slot. The power flow meter is electrically connected to a battery pack and is electrically connected to the light strip body.

[0010] Preferably, the crossbar has a rectangular cross-section, and the crossbar body is provided with correction platforms at equal intervals. Electromagnetic modules are symmetrically arranged on the left and right sides of the correction platforms. The correction platforms are symmetrically provided with sliding grooves, and magnetic strips are slidably fitted in the sliding grooves. The magnetic strips are symmetrically distributed on both sides of the light strip body. The magnetic poles of the magnetic strips and the electromagnet modules are the same on the symmetrical side. A small spring is connected to the side of the magnetic strip facing the electromagnet module. The small spring is connected to the inner wall of the sliding groove. An infrared emitter is provided at the top of the crossbar along the length direction.

[0011] Preferably, it also includes a support rod, the bottom of which is provided with multiple light source catchers. The light source catchers are located between two adjacent shower heads and are located directly above the infrared emitter. The light strip body is placed on the crossbar to block the infrared emitter. When a part of the light strip body bends and shifts to the side, the light emitted by the infrared emitter is exposed and shines on the light source catcher. At this time, the electromagnet module is energized to generate a magnetic field, which drives the magnetic strips on both sides of the light strip body to move closer to each other.

[0012] Preferably, it also includes a control module, which is located on the inner wall of the test slot and directly above the switch. The control module includes a U-shaped tube, a large spring, a piston rod, and an air chamber. The two ends of the U-shaped tube face downward and are aligned with the two ends of the switch. The U-shaped tube has symmetrically opened chambers. The upper end of the large spring is connected to the inner wall of the chamber, and the lower end of the large spring is connected to the piston rod. The lower end of the piston rod extends to the bottom of the U-shaped tube. The air chamber is located above the U-shaped tube and communicates with the chamber.

[0014] Preferably, the air chamber introduces air into the chamber and pushes the piston rod to move. The piston rod moves downward and touches the end of the switch. The large spring is stretched. When the upper end of the piston rod passes through the vent hole, the air pressure on the inner wall of the chamber is released, the piston rod loses its thrust, and the large spring contracts, causing the piston rod to rise.

[0015] Preferably, the drive unit includes an electric actuator and a connecting rod. The front and rear ends of the test groove are provided with through slots. The connecting rod extends into the test groove through the through slots. The lower end of the vertical rod is connected to the connecting rod.

Detailed Implementation

[0028] This invention provides a testing device for testing the energy efficiency and waterproofness of OLED lighting strips, such as...Figures 1-8 As shown, the light strip body 10 is tested, and a switch 101 is fixedly installed on the left end of the light strip body 10. It includes a test groove 1, and a crossbar 2 is welded in the test groove 1. Shower heads 81 are arranged at equal intervals on the crossbar 2. The light strip body 10 is placed on the crossbar 2. Multiple slide rails 21 are fixedly installed at the bottom of the crossbar 2. The slide rails 21 are connected to positioning components, which are used to fix the light strip body 10.

[0029] The positioning assembly includes a slide rod 6, a positioning rod 61, and a vertical rod 62. The slide rod 6 slides in conjunction with the slide rail 21, and its end bends upward through the slide rail 21. The positioning rod 61 is located above the horizontal bar 2, and its end bends downward, allowing it to be fixedly inserted into the end of the slide rod 6.

[0030] The bottom of the slide rod 6 is welded to the vertical rod 62, which extends vertically downward to the outside of the slide rail 21. When the positioning rod 61 is fixed together with the slide rod 6, it restricts the light strip body 10 to the horizontal rod 2.

[0031] A drive unit is connected to the outside of test slot 1, and the drive unit is connected to the vertical rod 62. A control module is also fixedly installed in test slot 1. The control module is electrically connected to each electronic component, and controls the operation of each electronic component through the control module. Since the control module is similar to a microcontroller and is a conventional technical means, its specific structure, circuit layout, and connection method are not described in detail or shown in the attached drawings.

[0032] During operation, the drive unit lowers the slide bar 6, causing the positioning rod 61 to engage with the crossbar 2. The positioning rod 61 engages with the crossbar 2, thereby fixing the light strip body 10, so that the light strip body 10 is held by the crossbar 2 and the positioning rod 61.

[0033] A power flow meter 15 and a battery pack 16 are fixedly installed on the outside of the test slot 1, and the power flow meter 15 is electrically connected to the battery pack 16. The input end of the power flow meter 15 is fixedly installed inside the test slot 1, and the lamp strip body 10 is fixed on the crossbar 2, and the lamp strip body 10 is electrically connected to the input end of the power flow meter 15.

[0034] The waterproof capability of the light strip is determined by spraying water onto it with a showerhead and observing whether the strip goes out upon contact with water. The power consumption of the light strip body 10 is monitored using a power flow meter 15, and the energy efficiency of the light strip is assessed based on this power consumption.

[0035] The crossbar 2 has a rectangular cross-section, and a correction platform 3 is fixedly installed at equal intervals on the crossbar 2. Electromagnetic modules 4 are symmetrically fixedly installed on both sides of the correction platform 3. The correction platform 3 has symmetrically opened grooves 31, within which magnetic strips 5 slide and engage symmetrically. The magnetic strips 5 are symmetrically distributed on both sides of the lamp strip body 10. The magnetic poles of the magnetic strips 5 and the electromagnet modules 4 are the same on their symmetrical sides. A small spring 32 is fixedly adhered to the side of the magnetic strip 5 facing the electromagnet modules 4, and the small spring 32 is welded to the inner wall of the groove 31. An infrared emitter 22 is fixedly installed along the length of the top of the crossbar 2.

[0036] It also includes a support rod 8, with multiple light source catchers 82 fixedly installed at the bottom of the support rod 8. The light source catchers 82 are located between two adjacent shower heads 81. The light source catchers 82 are located directly above the infrared emitter 22, and the light strip body 10 is placed on the crossbar 2 to block the infrared emitter 22.

[0037] Under normal conditions, the magnetic strip 5 does not touch the light strip body 10.

[0038] When a portion of the light strip body 10 bends and shifts to the side, the light emitted by the infrared emitter 22 is exposed and illuminates the light source catcher 82. After capturing the infrared light, the light source catcher 82 feeds the information back to the control module. This energizes the electromagnet module 4 to generate a magnetic field, causing the magnetic strips 5 on both sides of the light strip body 10 to move closer together, and the small spring 32 to stretch.

[0039] By bringing the magnetic strips 5 closer together, the offset area of ​​the light strip body 10 is corrected, thus restoring the light strip body 10 to its original position.

[0040] It also includes a control module 13, which is fixedly installed on the inner wall of the test slot 1 and located directly above the switch 101. The control module 13 includes a U-shaped tube 131, a large spring 132, a piston rod 133, and an air chamber 14. The two ends of the U-shaped tube 131 face downwards and are aligned with the two ends of the switch 101. The U-shaped tube 131 has symmetrically formed chambers 1311. The upper end of the large spring 132 is welded to the inner wall of the chamber 1311, and the lower end of the large spring 132 is welded to the piston rod 133. The lower end of the piston rod 133 extends below the U-shaped tube 131. The air chamber 14 is fixedly installed above the U-shaped tube 131 and communicates with the chamber 1311.

[0041] The upper end of the piston rod 133 contacts the inner wall of the chamber 1311, and the piston rod 133 and the chamber 1311 are in sliding fit. A vent hole 134 is opened at the lower end of the U-shaped tube 131. Branch pipes 141 are symmetrically welded to the bottom of the air chamber 14 and are connected to the chamber 1311. A motor is pivotally connected to the outside of the air chamber 14, and the motor drive shaft extends into the air chamber 14 and is welded with an isolation block 142. The isolation block 142 can rotate 90° to the left or right.

[0042] When the isolation block 142 rotates 90° to the left, the left branch pipe 141 is blocked, and air enters the right chamber 1311. When the isolation block 142 rotates 90° to the right, the right branch pipe 141 is blocked, and air enters the left chamber 1311.

[0043] Air chamber 14 introduces air into chamber 1311 and pushes piston rod 133 to move. Piston rod 133 moves downward and touches the end of switch 101. Large spring 132 is stretched. When the upper end of piston rod 133 passes through vent hole 134, the air pressure on the inner wall of chamber 1311 is released, piston rod 133 loses thrust, and large spring 132 contracts, causing piston rod 133 to rise.

[0044] As described above, the isolation block 142 rotates repeatedly, thereby controlling the piston rods at both ends of the U-shaped tube 131 to extend and retract alternately. This controls the opening and closing of the light strip switch 101.

[0045] The drive unit includes an electric actuator 9 and a connecting rod 7. Through slots 11 are provided at both the front and rear ends of the test groove 1. The connecting rod 7 extends into the test groove 1 through the slots 11. The lower end of the vertical rod 62 is welded to the connecting rod 7. The electric actuator 9 is fixedly installed on the outside of the test groove 1, and its lower end is welded to the connecting rod 7. When the electric actuator 9 extends downwards, it causes the connecting rod 7 to descend, which in turn pulls the vertical rod 62, causing the sliding rod 6 to descend.

[0046] The bottom of the test tank 1 is provided with an inclined surface, which causes water to converge towards the center of the bottom of the test tank 1. A drain hole 12 is provided at the center of the bottom of the test tank 1.

[0047] In summary, this testing equipment for the energy-saving and waterproof performance of OLED lighting strips includes a test chamber 1, a crossbar 2, a support rod 8, and a shower head 81. The strip body 10 is fixed to the crossbar 2, and the shower head 81 sprays water onto the strip 10 for a waterproof test. The energy-saving effect of the strip is measured using a power flow meter 15. The sliding rod 6 descends, causing the positioning rod 61 to engage with the crossbar 2, tightly clamping the strip body 10. The infrared emitter 22, the light source catcher 82, the electromagnet module 4, and the magnetic strip 5 work together to correct the strip body 10. The switch 101 controlling the strip body 10 is designed as a push-button type to reduce movement of the strip body 10, thus preventing inaccurate spraying due to fixture movement.
