[0002] In commercial lighting, industrial lighting, stage lighting, and high-end decorative lighting, luminaires are typically suspended from the ceiling, truss, or wall structure of a building. The reliability and safety of their installation are paramount. If a luminaire falls due to an insecure suspension structure, improper installation, or material fatigue, it can not only damage equipment but also endanger lives and property, potentially leading to serious safety accidents.

[0003] To ensure the structural stability and tensile strength of the luminaires during long-term suspended use, a suspended load test is required to verify their stability, connection reliability, and resistance to deformation under gravity.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0027] The inventors discovered through analysis of existing technology that:

[0028] 1. Traditional hoisting equipment has limited overall frame strength, and is prone to structural deformation, stress concentration or material fatigue during long-term or high-load testing, posing a safety hazard of lamp falling.

[0029] 2. Traditional equipment lacks precise control during lifting, positioning, or load application, which can easily lead to uneven load distribution and center of gravity shift, affecting the accuracy of the test or causing equipment failure or accidents.

[0030] 3. For large chandeliers, ceiling lights and other heavy and bulky lighting fixtures, traditional equipment usually requires multiple people to work together to complete the installation and fixing. In addition, it is difficult to adjust the height, angle and suspension point of the lighting fixtures, resulting in low operating efficiency.

[0031] 4. Existing testing equipment has limited compatibility and is difficult to flexibly accommodate lighting products of different shapes, installation methods, and weight levels.

[0032] Reference Figure 1 and Figure 2 This paper illustrates a lamp hanging tensile testing machine provided in an embodiment of the present application, which includes a main frame 1 and a lifting mechanism 2 disposed at the bottom of the main frame 1;

[0033] The main frame 1 has two suspension steel plates 3 in the first direction at the top, and two suspension arms 4 perpendicular to the suspension steel plates 3 are provided below the suspension steel plates 3. The suspension arms 4 are bolted to the suspension steel plates 3 through brackets 5, and the surfaces of the two suspension arms 4 are provided with first lamp mounting plates 6.

[0034] The side frame structure of the main frame 1 is provided with two crossbeams 8, and the crossbeams 8 are provided with screw clips, through which the second lamp mounting plate is installed;

[0035] When the lifting mechanism 2 rises to the target height, the lamp to be tested, with the test weight suspended on it, is installed on the first lamp mounting plate or the second lamp mounting plate, and the lifting mechanism descends to suspend the test weight in the air.

[0036] In the embodiments of this application, in contrast to the problems of "insufficient structural strength, load imbalance or material fatigue, inconvenient installation and adjustment, and poor compatibility and versatility" in the prior art, this application provides a solution for testing through a lifting mechanism, suspension components, and crossbeams. Specifically, it includes a main frame 1 and a lifting mechanism 2 located at the bottom of the main frame 1; two suspension steel plates 3 are provided in a first direction at the top of the main frame 1, and two suspension arms 4 perpendicular to the suspension steel plates 3 are provided below the suspension steel plates 3. The suspension arms 4 are bolted to the suspension steel plates 3 through brackets 5, and a first lamp mounting plate 6 is provided on the surface of the two suspension arms 4; two crossbeams 8 are provided on the side frame structure of the main frame 1, and the crossbeams 8 are provided with screw clips, through which a second lamp mounting plate is installed; when the lifting mechanism 2 rises to the target height, the lamp to be tested with a test weight is installed on the first lamp mounting plate or the second lamp mounting plate, and the lifting mechanism descends to suspend the test weight. The load-bearing capacity and structural stability of the equipment are improved through the load-bearing frame structure and lifting mechanism; the suspension steel plate, suspension arm and crossbeam can be used to accommodate lamps of different shapes and weights.

[0037] The following will further describe a lamp suspension tensile testing machine according to various exemplary embodiments of this application.

[0038] It should be noted that the main frame 1 is the structural foundation of the entire equipment, bearing all functional components. The lifting mechanism 2 is located at the bottom of the main frame 1 and is used to control the vertical lifting and lowering of the test weights and lamps, suspending the weights in the air to apply tension. The main frame 1 is equipped with a top suspension system and a side suspension system. The top suspension system is used for testing pendant lights and ceiling lights, while the side suspension system is used for testing wall lights.

[0039] As an example, two suspension steel plates 3 are installed along the length of the top of the main frame 1. These plates bear the load for lamp installation and testing. The suspension steel plates 3 are detachably installed on the top of the main frame 1 to accommodate testing requirements of lamps of different sizes. Two suspension arms 4 are installed below the suspension steel plates 3, extending along the width of the main frame 1. These arms are bolted to the suspension steel plates 3 via brackets 5, facilitating disassembly, assembly, and position adjustment to accommodate testing requirements of lamps of different sizes. The first lamp mounting plate 6 is used to install ceiling lights, pendant lights, and other top-mounted lamps.

[0040] The main frame 1 has two crossbeams 8 on its side frame structure. The screw clips on the crossbeams 8 can quickly lock and fix the second lamp mounting plate. The second lamp mounting plate is used to install side-mounted lamps such as wall lamps.

[0041] When the lifting mechanism 1 rises to a suitable height and the lamp to be tested with the test weight is installed on the corresponding mounting plate, the lifting mechanism descends to make the test weight completely suspended in the air. At this time, the lamp bears the weight, thus realizing the suspended tensile test.

[0042] In one specific implementation, the top of the working platform is a suspended steel plate 3, 10mm thick, with a hardened and blackened surface. Below the steel plate, 20mm thick plywood panels are arranged to simulate the actual installation environment and the installation of other light fixtures. Below this are two 30mm diameter hollow stainless steel suspension arms 4, mounted on the main load-bearing frame with stainless steel bracket bolts. These arms are detachable and their length and width can be manually adjusted to meet the installation requirements of different light fixture sizes. In the middle of the main frame, there are two crossbeams 8, equipped with four screw clips that allow for quick and easy locking of the mounting plate for wall lamp installation and load testing.

[0043] In one specific implementation, the total weight of the entire test is approximately 400KG, the external dimensions of the equipment are 1480*1080*2200mm (length:width:height), the lifting stroke of the equipment ranges from 500m to 1500m, the lifting speed is 50mm / s, and the load-bearing capacity of the stretching pallet is 0-800KG.

[0044] In this embodiment, the main frame 1 is constructed from industrial aluminum profiles to form a cabinet frame.

[0045] In one specific implementation, an integral load-bearing frame structure is formed by installing 80*80 industrial aluminum profiles, aluminum angle brackets, steel reinforcing angle plates, and stainless steel bolts and nuts to withstand the test weight of the test sample and suspended weights. The shape of the vertical cabinet frame can be cuboid, cube, etc., determined according to the overall size requirements of the equipment.

[0046] In this embodiment, the bottom of the main frame 1 is provided with four height-adjustable fixed feet 9 and four heavy-duty wheels 10.

[0047] It should be noted that the purpose of the fixing feet 9 is to keep the main frame level when the equipment is placed, by adjusting the height of the feet, thus preventing uneven ground from affecting the accuracy of the test and the stability of the equipment. The equipped heavy-duty wheels 10 facilitate easy handling when the equipment needs to be moved.

[0048] In one specific implementation, the bottom of the main frame is equipped with four height-adjustable fixed feet 9 and four universal heavy-duty wheels 10 with brakes for easy movement. The heavy-duty wheels have a braking function and can be locked when the equipment is working to prevent the equipment from moving.

[0049] In this embodiment, the first lamp mounting plate 6 or the second lamp mounting plate is a laminated plywood board.

[0050] It should be noted that plywood is a board made of multiple layers of veneer glued together. It is easy to process and can be drilled and cut as needed, making it convenient for the installation and fixing of light fixtures.

[0051] As an example, the plywood can be a three-, five-, or more-layered structure; its thickness can be 15mm, 20mm, 25mm, etc., depending on the requirements for the firmness of the lamp installation.

[0052] In this embodiment, the lifting mechanism has a working lifting plate on its surface. The working lifting plate is used to place test weights and connect lamps. It can be made of steel plate, alloy plate, or other materials.

[0053] In this embodiment, the lifting mechanism 2 is an electric single-scissor hydraulic lifting mechanism.

[0054] In one specific implementation, the testing machine's operating device is a manual control 3-button box: buttons for emergency stop, rise, and fall. The manually controlled electric single-scissor hydraulic lifting mechanism saves equipment space, has a strong load-bearing structure, stable speed, and fast reversal. It features a safety locking mechanism to prevent slippage after lifting stops. The rated load capacity is 1000KG; the minimum height is 205mm; the maximum height is 990mm; the platform dimensions are 1300mm (length) x 800mm (width); the hydraulic system drive motor has a voltage of 380V and a power of 1.1KW.

[0055] In this embodiment, the main frame 1 is provided with a protective railing 11, one of which is a double-opening hinged corner gate-type protective railing.

[0056] It should be noted that the protective railing 11 is designed to prevent injury to operators in the event of unexpected situations such as lamp suspension failure, weight set falling, or suspension wire breakage during testing. It also prevents external objects from interfering with the testing process. One side features a double-hinged corner gate-style protective railing. The hinges allow the gate to open and close flexibly, facilitating operators' access to the testing area for lamp installation, weight placement, and other operations.

[0057] In one specific implementation, to prevent the failure of the lamp suspension, the weight set, or the suspension wire, and to facilitate visual observation of the test, a safety guardrail is configured. The main frame is bolted on three sides and hinged corner gate type on one side. The aperture of the guardrail is 20*80mm; the wire diameter is 3.5mm, and the steel wire is welded into a structure reinforced with 20*20 steel square tubes on all four sides. The surface is sprayed with yellow electrostatic powder paint.

[0058] In this embodiment, a positioning beam is provided on the top of the suspended steel plate, and the positioning beam is perpendicular to the suspended steel plate. The positioning beam is used to assist in the positioning and installation of the suspended steel plate.

[0065] 5. After completing the above steps, press the lowering button on the electric hydraulic lifting platform to suspend the test weights completely so that the force is fully applied to the lamp for testing.

[0066] 6. The test lasts for 1 hour to determine if the lamps are at risk of falling, deforming, or failing.

[0067] II. Testing methods for wall lamp products:
