Description

[0002] First of all, as a light source widely used in indoor and outdoor lighting, decoration, signal indication and other fields, LED lights have various working characteristics and requirements. Different LED lamps and different application scenarios may require different voltage or current supply.

[0003] However, the existing power drivers are often unable to meet such diverse needs because they cannot adjust the output gear. This results in that in actual applications, users may need to select power drivers of different specifications according to different LED lamps and application scenarios, which increases the cost of use and the difficulty of maintenance.

If the output of the power driver exceeds the tolerance range of the LED lamp, it may cause damage to the lamp or performance degradation. In some special application environments, such as high temperature, high humidity and other harsh conditions, this potential risk may be more significant. Utility Model Content

[0033] A power driver with selectable output end, comprising a housing 1, wherein an output end selection module 2 and a circuit board are sequentially installed in the housing 1;

[0034] The output end selection module 2 is provided with a selection gear 21 and a control shaft 22, the selection gear 21 is rotatably sleeved on the end of the control shaft 22, the control shaft 22 is electrically connected to the circuit board, the end of the selection gear 21 passes through the housing 1, the control shaft 22 is provided with a plurality of output end gears, and the selection gear 21 is used to select one of the output end gears;

[0035] The circuit board is electrically connected to a code dial 3 .

[0036] The present invention provides a power driver with a selectable output end. The circuit board is electrically connected to a code dial 3. The code dial 3 can change the configuration of the internal circuit of the power driver of the present invention to adjust different output parameters. The circuit board is also electrically connected to an output end selection module 2. The output end selection module 2 includes a selection gear 21 and a control shaft 22. The control shaft 22 is provided with a plurality of output end gears. Since the end of the selection gear 21 passes through the housing 1, the user can select one of the output end gears by rotating the selection gear 21.

[0037] The combination of the encoder 3 and the output terminal selection module 2 allows the power driver to set more output current gears, and the output terminal selection module 2 can select a specific output terminal gear, thereby solving the problem that the traditional power driver cannot adjust the output terminal gear.

[0038] The housing 1 comprises an upper shell 11 and a lower shell 12. The inner wall of the lower shell 12 is provided with a limiting plate 14. The limiting plate 14 abuts against the circuit board.

[0039] The upper shell 11 is provided with a clearance groove 13 , and the clearance groove 13 is arranged opposite to the code dial 3 , and the code dial 3 is exposed to the outside through the clearance groove 13 .

[0040] The upper shell 11 and the lower shell 12 adopt a pre-designed snap-on structure, which makes the connection between the various components simple and fast. When the power driver of this solution needs to be disassembled or repaired, the user can easily separate the upper shell 11 and the lower shell 12 to facilitate inspection and replacement of the internal circuit board and the dial 3.

[0041] Moreover, the upper shell 11 is provided with an air-avoiding groove 13, which can expose the code dial 3 to the outside, so that the user can directly observe and operate it, and can easily set and adjust the parameters of the driver without opening the shell 1. When maintaining or repairing the power driver of this solution, the user can quickly check the status of the code dial 3 without disassembling the shell 1.

[0042] A selection conductive sheet 211 is provided on the inner side of the selection gear 21, and a plurality of first wire sheets 221 are provided on the control shaft 22. The first wire sheets 221 are movably connected to the circuit board, and the ends of the plurality of first wire sheets 221 are all located at the center of the control shaft. The head ends of the plurality of first wire sheets 221 are radially extended outward, and the selection conductive sheet 211 is in contact with one of the first wire sheets 221.

[0043] The user rotates the selection gear 21, and the selection gear 21 drives the selection conductive sheet 211 to rotate together, so that the selection conductive sheet 211 inside the selection gear 21 sequentially contacts with different first conductive sheet 221. When the rotation of the control shaft 22 is stopped, the selection conductive sheet 211 contacts with one of the first conductive sheet 221, and the circuit is connected to form a closed circuit, so that the corresponding output end gear is selected.

[0044] The user can intuitively select the desired output end gear by rotating the control shaft 22. Compared with other output end gear selectors, this output end gear selection structure is simpler and has a lower manufacturing cost.

[0045] When the plurality of first conductive sheets 221 are radiated outward in a windmill shape, the positions of the plurality of first conductive sheets 221 can be clearly distinguished, ensuring that the corresponding output terminal position can be accurately selected by selecting the conductive sheet 211 .

[0046] The side wall of the control shaft 22 is provided with a plurality of first electrode sheets 222, the first electrode sheets 222 are connected to the first wire sheets 221, the plurality of first electrode sheets 222 correspond to the plurality of first wire sheets 221 one by one, and the plurality of first electrode sheets 222 movably pass through the upper shell 11 or the lower shell 12;

[0047] The first electrode sheet 222 is electrically connected to the circuit board.

[0048] Rotate the control shaft 22 to connect the first motor sheet to the circuit board, and then rotate the selection gear 21 to make the selection conductive sheet 211 on the selection gear 21 abut against one of the first conductor sheets 221. At this time, the circuit is connected, thereby quickly adjusting the output gear position of the power driver of this scheme, thereby improving the flexibility and convenience of the power driver of this scheme.

[0049] The control shaft 22 is fixedly sleeved with a first handle 223 . The connecting end of the first handle 223 is fixedly connected to the control shaft 22 , and the gripping end of the first handle 223 passes through the housing 1 .

[0050] In this embodiment, the gripping end of the first handle 223 extends out of the housing 1, so that the user can easily grasp the first handle 223 and rotate the first handle 223 to drive the control shaft 22 to rotate, thereby connecting the plurality of first wire sheets 221 to the circuit board. This design significantly improves the convenience of operation, allowing the user to quickly and accurately perform the required operation.

[0051] A signal shaft 4 is further provided in the housing 1 , and the signal shaft 4 is located at an end of the circuit board away from the output end selection module 2 . The signal shaft 4 is provided with two oppositely arranged second electrode sheets 41 , and one of the second electrode sheets 41 is movably connected to the circuit board.

[0052] The two second electrode sheets 41 on the signal shaft 4 correspond to two signal lines respectively. The signal shaft 4 is rotated so that one of the second electrode sheets 41 is connected to the circuit board, so that different signal lines can be quickly selected.

[0053] The signal shaft 4 is fixedly sleeved with a second handle 42 . The connecting end of the second handle 42 is fixedly connected to the signal shaft 4 , and the gripping end of the second handle 42 passes through the housing 1 .

This design significantly improves the convenience of operation, allowing the user to quickly and accurately perform the required operation.

[0055] The head end of the selection conductive sheet 211 is obliquely connected and installed on the inner side of the selection gear 21 . The inner wall of the selection gear 21 is provided with a pressing block 212 . The pressing block 212 is used to separate the selection conductive sheet 211 from the selection gear 21 .

[0056] Reference Figure 3The selection conductive sheet 211 is installed tilted to ensure that the selection conductive sheet 211 can abut against the first conductive sheet 221, thereby connecting the circuit. The pressing block 212 can effectively separate the selection conductive sheet 211 from the selection gear 21, further ensuring that the selection conductive sheet 211 can abut against the first conductive sheet 221.
