Technical Field
[0001] This utility model relates to the field of dimming power supply technology, specifically to a dimming and color-adjusting power supply. Background Technology
[0002] As people's living standards improve, their demands for lighting are also constantly increasing. In some daily life scenarios, it is necessary to adjust the color temperature and brightness of lights. Existing dimming solutions typically involve a dimmer or dimming system sending a dimming command to the power supply. Upon receiving the dimming signal, the power supply adjusts its output to regulate the brightness or color temperature of the lights. However, this method is cumbersome to wire and requires the purchase of a matching dimmer and a power supply that can receive compatible dimming signals. To address these technical issues, some manufacturers have developed products that integrate the power supply and dimmer within a switch-sized housing. However, these products have low power density and cannot meet the needs of high-power applications. Utility Model Content

Detailed Implementation
[0023] The embodiments of this utility model are described in detail below, with reference to Figures 1 to 3 This utility model provides a dimming and color-adjusting power supply, including a control panel 100 and a back cover 200. The control panel 100 is equipped with a push-button rotary encoder 110, and the back cover 200 houses a control circuit board 300. The push-button rotary encoder 110 is a rotary encoder integrating a button; the knob can rotate to drive the encoder to rotate while also being pressed, thus functioning as a push-button switch. The back cover 200 is located on the back side of the control panel 100, and its surface is provided with wiring terminals 2112. The control circuit board 300 is equipped with a control circuit and is electrically connected to the push-button rotary encoder 110 and the wiring terminals 2112. The control circuit board 300 includes a main board 310 and multiple sub-boards 320 mounted on the main board 310. The electrical components of the control circuit are distributed on the main board 310 and the sub-boards 320.
[0024] This dimming and color-changing power supply integrates the functions of a dimmer and a power source, eliminating the need for separate wiring between the dimmer and power source during installation, making installation convenient. By directly coordinating the electrical signals generated by the pressing and rotating actions of a single control device (press switch, knob, encoder 110), it can achieve both light switching and brightness and color temperature adjustment with a single control unit. This reduces the number of control components on the control panel 100, thereby reducing the product's size and avoiding the space occupied by control components in the power supply, thus increasing the product's power density. Simultaneously, the control circuit board 300 adopts a three-dimensional layout structure composed of a main board 310 and a sub-board 320, which makes fuller use of the space within the rear casing 200, further increasing the product's power density without increasing its size. This dimming and color-changing power supply achieves higher output power without significantly increasing the product's size, making it suitable for high-power applications.
[0025] Reference Figure 6 The control circuit includes a switching power supply circuit, an adjustment circuit, and a main control circuit. The input terminal of the switching circuit is electrically connected to the input terminal in terminal block 2112. The output terminal of the switching power supply circuit is electrically connected to the input terminal of the adjustment circuit and the main control circuit, supplying power to the adjustment circuit and the main control circuit. The output terminal of the adjustment circuit is electrically connected to the output terminal in terminal block 2112. The adjustment circuit is controlled by the main control circuit, which is electrically connected to the push-button encoder 110.
[0026] Reference Figure 7 In this embodiment, the adjustment circuit includes at least two output adjustment circuits. The output terminals of the two output adjustment circuits are electrically connected to two different output terminals in the wiring terminal 2112, respectively, for adjusting the brightness and color temperature of the lamp load. The control circuit may also include a wireless control module, which is electrically connected to the main control circuit and is used to receive wireless control signals to achieve wireless dimming control of the lamp load. In this embodiment, the push-button encoder 110 outputs three signals to the main control circuit, including two pulse signals (A phase and B phase) and one switch signal. The main control circuit determines the direction of the knob based on the two pulse signals to determine the direction of brightness and color temperature adjustment. The main control circuit can use the switch signal to help determine whether to adjust the color temperature, brightness, or control the lamp switch, such as switching the knob function by the pressing time or the frequency of continuous short presses, so as to realize the input of multiple control signals by a single controller.
[0027] Reference Figure 2 , Figure 4 and Figure 5To facilitate product maintenance and repair, both the control panel 100 and the control circuit board 300 adopt a modular design. A first electrical connector 102 is located on the back of the control panel 100, and a second electrical connector 2111, matching the first electrical connector 102, is located on the front of the rear cover 200. The first electrical connector 102 is electrically connected to the push-button encoder 110, and the second electrical connector 2111 is electrically connected to the control circuit board 300. The control panel 100 can achieve electrical connection between the push-button encoder 110 and the control circuit board 300 through the insertion of the first electrical connector 102 and the second electrical connector 2111. The rear cover 200 and the control panel 100 are detachably connected. When either the control panel 100 or the control circuit board 300 is damaged, the damaged module can be disassembled and replaced for quick product maintenance or repair. In this embodiment, the control panel 100 is provided with an encoder signal processing circuit board 112 for processing the pulse signals of the push-button knob encoder 110.

The inner shell 210 and the control circuit board 300 constitute a control module and are mechanically connected to the control panel 100 through the outer shell 220. The inner shell 210 is formed by the front shell 211 and the rear cover 212, which together form a space for accommodating the control circuit board 300. The outer shell 220 consists of a connecting cover 221 and a side shell 222. The connecting cover 221 is detachably connected to the back side of the control panel 100. After the connecting cover 221 is connected to the control panel 100, it forms the back plate of the control panel 100 to protect the back side of the encoder signal processing circuit board 112. The side shell 222 is a barrel-shaped housing, and its shape matches that of the inner shell 210. The inner shell 210 can be inserted into the side shell 222, thereby connecting the inner shell 210 and the outer shell 220. The second electrical connector 2111 is located on the front of the front shell 211, and the terminal block 2112 is located on the side of the front shell 211. The connecting cover 221 has a clearance hole 2221 to avoid the second electrical connector 2111 on the front shell 211. The side of the side shell 222, corresponding to the location of the terminal block 2112, is also designed to avoid the terminal block 2112, facilitating the exposure of the wiring.
