Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more features. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a link, or a specific connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the connection within two groups. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0036] like Figures 1-7 As shown, in its first aspect, this utility model proposes an integrated dual-mode LED controller, which is connected to an external system 600 and at least one light-emitting unit 700. The integrated dual-mode LED controller includes a main control module 100, a receiving module 200, an identification module 300, an output module 400, and a power supply module 500. The power supply module 500 is electrically connected to the main control module 100, the receiving module 200, the identification module 300, and the output module 400 to supply power. The receiving module 200 is electrically connected to the external system 600, the main control module 100, and the identification module 300 to receive control signals from the external system 600 and transmit the control signals to the main control module 100 and the identification module 300. The identification module 300 is used to detect the signal transmission status of the receiving module 200. The output module 400 is electrically connected to the main control module 100 and each light-emitting unit 700 to control the on / off state of each light-emitting unit 700.

[0037] In this embodiment, the specific implementation is as follows: The receiving module 200 is connected to the external system 600 and receives control signals from the external system 600. The identification module 300 detects the signal transmission status of the receiving module 200 to determine whether the receiving module 200 has received a signal from the external system 600. If a signal input is detected, the identification module 300 transmits a signal to the main control module 100. The main control module 100 immediately shuts down the built-in lighting program and sends the data signal received by the receiving module 200 to the output module 400 to control the corresponding light-emitting unit 700. If the identification module 300 does not identify a signal output from the receiving module 200 for a relatively long time (within a preset time of 3 seconds), the identification module 300 transmits a signal to the main control module 100. The main control module 100 sends its built-in lighting program to the output module 400 to control the corresponding light-emitting unit 700. It should be noted that the receiving module 200 will perform shaping processing on the received signal before transmitting it to the main control module 100.

[0038] For the receiver module 200, only one signal receiving method is specified, which involves direct wiring to connect to the external control system. This method is the optimal solution in terms of cost and space when the external control system is not far from the light fixture. Other signal receiving methods are also possible, including adding Bluetooth, Wi-Fi, Zigbee, or LoRa modules to the receiver module 200 to achieve remote wireless control of the integrated dual-mode LED controller.

[0039] In one embodiment of this application, an integrated dual-mode LED controller is built into one of the light-emitting units 700.

[0040] The control signals include TTL signals and return-to-zero codes.

[0041] The light-emitting unit 700 includes an LED lamp 701 and a driving module 702. The driving module 702 is electrically connected to the LED lamp 701, and the output module 400 is electrically connected to the driving module 702.

[0042] The receiving module 200 includes a single-channel buffer U4201, a fuse F2202, a diode D4203, a capacitor C8204, and a resistor R7205. One end of the fuse F2202 is connected to the external system 600, and the other end of the fuse F2202 is electrically connected to the single-channel buffer U4201. The positive terminal of the diode D4203 is grounded, and the negative terminal of the diode D4203 is electrically connected to the single-channel buffer U4201. The capacitor C8204 is electrically connected to the power module 500 and grounded. The single-channel buffer U4201 is grounded and electrically connected to the power module 500 and the resistor R7205, respectively. The resistor R7205 is electrically connected to the main control module 100.

[0043] It should be noted that fuse F2 is a PTC resettable fuse, and diode D4 is a transient voltage suppressor diode. The single-channel buffer U4201 uses a 1.65V to 5.5V single-channel buffer SN74LVC1G17 U4 with Schmitt trigger input as the external signal receiver. This effectively shapes low-amplitude high-level signals and high-amplitude low-level signals, preventing abnormal decoding of the LED 700. The PTC resettable fuse F2 and transient voltage suppressor diode D4 effectively protect the downstream modules. When there is an external high-voltage pulse, the transient voltage suppressor diode D4 exhibits a low-impedance state, absorbing the external high voltage. The resulting instantaneous large current causes the resettable fuse F2 to lose conductivity, effectively opening the circuit and preventing continuous, long-term impacts from damaging the circuit. Capacitor C8 is a decoupling capacitor to filter power supply noise. Resistor R7 is a current-limiting resistor to provide impedance matching for the circuit.

[0044] In one embodiment of this application, the output module 400 includes a single-channel transceiver U3401, a fuse F1402, a diode D3403, a capacitor C6404, and a resistor R5405. The resistor R5405 is electrically connected to the main control module 100 and the single-channel transceiver U3401. The positive terminal of the diode D3403 is grounded, and the negative terminal of the diode D3403 is electrically connected to the single-channel transceiver U3401. The capacitor C6404 is electrically connected to the power module 500 and grounded. The single-channel transceiver U3401 is grounded and electrically connected to the power module 500 and the fuse F1402. The fuse F1402 is electrically connected to the drive module 702.

[0045] The U3401 single-channel transceiver uses the SN74LVC1G17 single-channel transceiver with push-pull output. F1402 is a PTC resettable fuse F1, and diode D3403 is a transient voltage suppressor diode D3. Similarly, capacitor C6 is a decoupling capacitor to filter power supply noise, and resistor R7 is a current-limiting resistor to provide impedance matching for the line. The transient voltage suppressor diode D3 protects the output port of the SN74LVC1G17 single-channel transceiver U3 from high-energy surges. If the output circuit is subjected to continuous high-voltage pulses, the resettable fuse F1 will disconnect the circuit, preventing the transient voltage suppressor diode D3 and the output port of the SN74LVC1G17 single-channel buffer U3 from absorbing excessive energy and being damaged. After the external pulses cease, the resettable fuse F1 automatically returns to its normal state.

[0046] In one embodiment of this application, the main control module 100 adopts the STC8H3K64S2, which has rich resource interfaces, sufficient memory space, and can be configured with a library of preset light effects for various complex algorithms (shooting stars, starry sky, candlelight, flowing water, dynamic scene transitions). These effect data are transmitted to the signal output module through the chip serial port, so that the lamp is no less than the level of external controller solution in terms of visual smoothness, color richness and naturalness of change.

[0047] In one embodiment of this application, the power module 500 is model LMR16006, which has a wide voltage input range and can be used in lamps with more voltage types. At the same time, the low ripple voltage output by the power module supplies power to other modules of this utility model.

[0048] In a second aspect, this utility model proposes an intelligent lighting fixture, which includes an integrated dual-mode LED controller as described in any of the above schemes, at least one light-emitting unit 700, and a power supply. The integrated dual-mode LED controller is electrically connected to each light-emitting unit 700, and the power supply is electrically connected to each light-emitting unit 700.

[0049] In this embodiment, the smart lamp includes two working modes. One mode is that the external system and the light-emitting unit 700, which integrates the integrated dual-mode LED controller, are powered on at the same time. The external system sends a control signal (TTL signal, return-to-zero code signal) to the integrated dual-mode LED controller, which outputs the received signal to the light-emitting unit 700 with almost no delay.

[0050] Secondly, the light-emitting unit 700, which integrates the integrated dual-mode LED controller, is directly powered on. After being powered on, the light-emitting unit 700 displays the light effect of the built-in lighting program of the integrated dual-mode LED controller. Then, when the external system is powered on, the integrated dual-mode LED controller detects the external signal (TTL signal, return-to-zero code signal), immediately shuts off the internal light effect data, accurately analyzes and receives the external data, outputs the received data, and drives the light-emitting unit 700.

[0051] See attached Figure 3 In the second embodiment, the integrated dual-mode LED controller is not connected to the external system 600, so that as long as the power is turned on, the lamp can automatically display various smooth and colorful preset light effects after 3 seconds.

[0052] It should be noted that the above descriptions are one or more embodiments provided in conjunction with specific content, and do not imply that the specific implementation of this utility model is limited to these descriptions. Any methods or structures that are similar to or identical to those of this utility model, or any technical deductions or substitutions made based on the concept of this utility model, should be considered within the scope of protection of this utility model.
