[0053] The following combines the attached Figures 1 - 9 The technical solutions of this embodiment are elaborated in detail. Without conflict, the following implementation manners and embodiments can be combined with each other.
[0054] Embodiment 1
[0055] As Figure 1 shown, the present application provides a lighting control device, including a power supply module, an adaptive wiring module, and a control module.
[0056] Power supply module;
[0057] Adaptive wiring module, including:
[0058] A plurality of load connection terminals, forming an electrical connection with the load lamps, and each load connection terminal corresponds to a different lamp function channel;
[0059] A load detection unit, electrically connected to a plurality of load connection terminals;
[0060] A control module, which outputs a first control instruction to the load detection unit. The load detection unit is configured to activate the output signals of each load connection terminal after receiving the first control instruction, collect the level status information corresponding to each load connection terminal, and send it to the control module;
[0061] Among them, the control module is configured to identify the lamp type of the load lamp according to the level status information, and switch to the corresponding control mode according to the lamp type. The power supply module is electrically connected to the control module and the adaptive wiring module, and is used to supply power to the control module and the adaptive wiring module.
[0062] In some embodiments, the ways for the control module to output the first instruction to the load detection unit to activate each load terminal include but are not limited to: activating multiple load connection terminals simultaneously or activating each load terminal in a preset order sequentially.
[0063] In some embodiments, the specific implementation method of activating multiple load connection terminals simultaneously is as follows: The control module outputs a signal to a group of load connection terminals (such as the cold / warm light group C / W or the full-color group R / G / B), so that the corresponding terminals output drive signals simultaneously. The load detection unit collects the level status information of each activated terminal in parallel. The control module matches the preset lamp type according to the combined level status information, or generates composite level status information by combining multiple groups of detection results for lamp type identification. After the identification is completed, the control module automatically calls the corresponding control logic (such as independently adjusting the cold / warm light color temperature or mixing the RGB spectrum) to control the load lamp.
[0064] In some embodiments, as Figure 1 shown, the lamp function channels corresponding to the load connection terminals include but are not limited to: the cold white light channel (C), the white light channel (W), the red light channel (R), the green light channel (G), and the blue light channel (B). The load connection terminals adopt a standardized interface, such as a pluggable terminal, which is convenient for quickly connecting the load lamp. The arrangement order of the load connection terminals is not fixed and can be flexibly adjusted according to the hardware design, wiring optimization, or user habits. Figure 1 The arrangement order of the load terminals shown is only one of the arrangement orders.
[0065] In some embodiments, the terminal abbreviations (such as silk-screen printing C, W, R, G, B) are clearly marked on the lamp housing or circuit board, which is convenient for installers to quickly identify. Hereinafter, each load connection terminal will be referred to as the C terminal, the W terminal, the R terminal, the G terminal, and the B terminal respectively.
[0066] In some embodiments, the lamp function channels corresponding to the load connection terminals are not limited to the above five channels, and other function channels can be extended according to actual needs. For example: the ultraviolet light channel (UV), which is used to represent ultraviolet light lamps and is often used for specific lighting effects or disinfection functions; the infrared light channel (IR), which is used to represent infrared light lamps and is often used for heating or specific induction functions. The amber light channel (A) is used to supplement the warm color spectrum and improve color rendition, etc.
[0067] In some embodiments, as Figures 2 - 6 shown, the lamp types include but are not limited to: single-brightness (W) lamps, cool-white and warm-white (CW) lamps, color (RGB) lamps, white and color (WRGB) lamps, cool-white and warm-white and color (CWRGB) lamps. The wiring configurations of various types of lamps will be specifically described below with reference to the drawings.
[0068] As Figure 2 shown, the wiring method of the single-brightness (W) lamp is to only connect the W terminal (white light channel), and the C terminal, R terminal, G terminal, and B terminal are left floating.
[0069] As Figure 3 shown, the wiring method of the cool-white and warm-white (CW) lamp is to connect the C terminal (cool-white light channel) and the W terminal (white light channel), and the R terminal, G terminal, and B terminal are left floating.
[0070] As Figure 4 shown, the wiring method of the color (RGB) lamp is to connect the R terminal (red light channel), G terminal (green light channel), and B terminal (blue light channel), and the C terminal and W terminal are left floating.
[0071] As Figure 5 shown, the wiring method of the white and color (WRGB) lamp is to connect the W terminal (white light channel), R terminal (red light channel), G terminal (green light channel), and B terminal (blue light channel), and the C terminal is left floating.
[0072] As Figure 6 shown, the wiring method of the cool-white and warm-white and color (CWRGB) lamp is to connect the C terminal (cool-white light channel), W terminal (white light channel), R terminal (red light channel), G terminal (green light channel), and B terminal (blue light channel).
[0073] In some embodiments, the lamp types are not limited to the above five types and can be extended according to actual needs. For example, the wiring method of the ultraviolet light (UV) lamp is to connect the UV terminal (ultraviolet light channel), and the other terminals are left floating; the wiring method of the infrared light (IR) lamp is to connect the IR terminal (infrared light channel), and the other terminals are left floating, etc.
[0074] Preferably, the load detection unit is further configured to send a first level signal to the control module when the load connection terminal is connected to the load lamp; when the load connection terminal is not connected to the load lamp, the load detection unit sends a second level signal to the control module.
[0075] In some embodiments, the definitions of the first level signal and the second level signal support positive or negative logic, specifically including:
[0076] If it is a positive logic mode, when the load lamp is connected, the load detection unit sends a high level signal (the first level signal) to the control module; when the load lamp is not connected, the load detection unit sends a low level signal (the second level signal).
[0077] If it is a negative logic mode, when the load lamp is connected, the load detection unit sends a low level signal (the first level signal) to the control module; when the load lamp is not connected, the load detection unit sends a high level signal (the second level signal).
[0078] Preferably, the load detection unit is further configured to, after receiving the first control instruction, activate the output signals of each load connection terminal in a preset order, collect the level status information corresponding to each load connection terminal and send it to the control module. The control module generates a level coding sequence according to the level status information and identifies the lamp type according to the level coding sequence.
[0079] Preferably, the control module is further configured to match based on the level coding sequence and a preset lamp type mapping table to identify the lamp type.
[0080] In some embodiments, taking the positive logic mode of the level signal as an example below, when the preset order is to light the C terminal, W terminal, R terminal, G terminal, and B terminal in sequence, the lamp type mapping table is shown in Table 1. Table 1 details the lamp types corresponding to different level coding sequences, where the level coding sequence represents the level status information of each load connection terminal, 1 represents a high level signal, and 0 represents a low level signal. By detecting this level status information, the control module can accurately identify the connected lamp type and automatically match the corresponding control method to achieve precise control of the lamp.
[0081] Table 1: Lamp Type Mapping Table
[0082] Serial number Level information Lamp type 1 01000 Single - brightness (W) lamp 2 11000 Cool - white and warm - white (CW) lamp 3 00111 Color - light (RGB) lamp 4 01111 White - light and color - light (WRGB) lamp 5 11111 Cool - white / warm - white and color - light (CWRGB) lamp
[0083] In some embodiments, the preset order can be adjusted according to actual needs. Similarly, the lamp type mapping table can be extended and updated according to different preset orders or newly added lamp types to adapt to more types of lamp types. This flexibility enables the present invention to better adapt to different application scenarios and user requirements, further enhancing compatibility and versatility.
[0084] Preferably, the load detection unit includes:
[0085] An MOS transistor array, electrically connected between the PWM control pin and the load connection terminal;
[0086] A PWM control pin, electrically connected to the control module, configured to output pulse signals to the MOS transistors corresponding to each load connection terminal in a preset order to sequentially activate the outputs of each load connection terminal;
[0087] A level detection pin, connected to the load connection terminal through a voltage division circuit, for monitoring the load status of each load connection terminal and outputting level status information.
[0088] Preferably, the voltage division circuit includes a series-connected current-limiting resistor and a pull-down resistor, and their resistance values are configured such that: when a lamp is connected to the load connection terminal, the voltage of the level detection pin is higher than the threshold voltage, and the level detection pin outputs a high-level signal; when no lamp is connected to the load connection terminal, the voltage is lower than the threshold voltage, and the level detection pin outputs a low-level signal.
[0089] In some embodiments, as Figure 7 shown, the circuit structure of the load detection unit includes:
[0090] The MOS transistor array includes Q1, Q2, Q3, Q4, and Q5. The MOS transistors are used as switching devices to control the output signals of each load connection terminal. They are electrically connected between the PWM control pin and the load connection terminal. Each MOS transistor corresponds to a load connection terminal, and the on and off of the MOS transistors are controlled by the pulse signals output by the PWM control pin. When the PWM control pin outputs a high level, the corresponding MOS transistor conducts, and the load connection terminal outputs a signal; when the PWM control pin outputs a low level, the MOS transistor cuts off, and the load connection terminal stops outputting a signal.
[0091] The PWM control pin is used to output pulse signals to control the on and off of the MOS transistors. The PWM control pin is electrically connected to the control module and is connected to the gates of the MOS transistor array. The control module outputs pulse signals in a preset order through the PWM control pin to sequentially activate the outputs of each load connection terminal. For example, the control module can output pulse signals in the order of the C terminal, W terminal, R terminal, G terminal, and B terminal to make each load connection terminal output signals in sequence.
[0092] The level detection pin is used to monitor the load status of each load connection terminal and output level status information. The level detection pin is connected to the load connection terminal through a voltage division circuit. The voltage division circuit consists of a current limiting resistor and a pull-down resistor. When a lamp is connected to the load connection terminal, current flows through the current limiting resistor, causing the voltage of the level detection pin to rise and exceed the threshold voltage, thereby outputting a high-level signal; when no lamp is connected to the load connection terminal, the pull-down resistor pulls down the voltage of the level detection pin below the threshold voltage, thereby outputting a low-level signal.
[0093] In some embodiments, as Figure 7 shown, the pull-down resistor in the voltage division circuit is R11, ensuring that the GPI pin remains at a low level when no light bar is connected.
[0094] In some embodiments, as Figure 7 shown, the voltage division resistors in the voltage division circuit are R5, R6, R7, and R8, which are resistors with a specification of 43KΩ. The voltage division resistors and R11 together form a voltage division circuit for detecting the load connection status. When a load lamp is connected, current flows through R5 - R8, causing the voltage of the GPI pin to rise and exceed the threshold voltage, thereby outputting a high-level signal; when no load lamp is connected, R11 pulls down the GPI pin, and the voltage is lower than the threshold voltage, outputting a low-level signal.
[0095] Preferably, the control module includes:
[0096] A PWM driving unit, including a multi-channel PWM signal generator and a MOS transistor switch array. The output terminal of each PWM signal generator is connected to the gate of the corresponding MOS transistor, and the source or drain of the MOS transistor directly drives the load connection terminal to achieve control of the load lamp.
[0097] In some embodiments, as Figure 8 shown, the circuit structure of the control module includes a PWM driving unit and a MOS transistor switch array for achieving precise control and driving of the lamp. The PWM driving unit includes a multi-channel PWM signal generator. The output terminal of each PWM signal generator is connected to the gate of the corresponding MOS transistor, and the on and off of the MOS transistor are controlled by outputting pulse signals. The MOS transistor switch array, as a switching device, controls the output signals of each load connection terminal, and the source or drain of the MOS transistor directly drives the load connection terminal. The control module outputs pulse signals in a preset order through the PWM signal generator, sequentially activates the outputs of each load connection terminal, and detects the load status through the level detection pin to generate a level coding sequence, identify the lamp type, and automatically match the corresponding control method to achieve precise control of the lamp.
[0098] Preferably, the control module is further configured to: if the level coding sequence does not match any preset lamp types, enter the default safety mode, turn off the outputs of all load connection terminals, and feedback abnormal information through the status indicator or communication interface.
[0099] In some embodiments, as Figure 9 shown, the power supply module is a key component of the lamp system, responsible for providing stable power for the control module and the adaptive wiring module. The power supply module can achieve multi-level voltage output. Specifically, the power supply module can convert the input power into a first DC voltage to supply power to the load driving circuit of the adaptive wiring module, ensuring stability in high-current scenarios; at the same time, the power supply module can generate a second DC voltage through an integrated voltage stabilizing unit to supply power to the logic circuit and sensors of the control module, meeting the requirements of low noise and high precision.

[0105] Step S4: The control module automatically switches to the adapted control method according to the identified lamp type, and calls the corresponding control method to control the load lamp.
[0106] Preferably, step S2 further includes:
[0107] When the load connection terminal is connected to the load lamp, the load detection unit sends a first level signal to the control module; when the load connection terminal is not connected to the load lamp, the load detection unit sends a second level signal to the control module.
