Please refer to FIG. 2, the rectification and data separation circuit 10 is mainly based on the diode D1, and a pulse signal is formed on the electric wire 11a, which is rectified by the diode D1 and the capacitor C1. Working power, the upper end of the resistor RL is a control signal. As shown in FIG. 3, the rectification and data separation circuit 10 is mainly a bridge rectifier. When applied, a pulse signal is formed on the electric wire 11a, which is rectified by the diode D5 and the capacitor C1, and works at both ends of the capacitor C1. Power, the upper end of the resistor RL is the control signal; please refer to FIG. 4, if the pulse signal is connected to the 11b electric wire, after rectified by the diode D5 and the capacitor C1, the working power is generated at both ends of the capacitor C1, the resistor RL The upper end also receives control signals. In this way, no matter how the two electrical wires 11a and 11b are connected to the external controller, the working power can be obtained on the capacitor C1, and the control signal can be obtained on the resistor RL. In the rectification and data separation circuit 10, when there is no pulse signal on the electric wires (such as the electric wires 11a of FIGS. 2 and 3 and the electric wires 11b of FIG. 4), a constant voltage will be maintained on the electric wires, thus across the capacitor C1 A high voltage will be generated, while the upper end of the resistor RL remains at a constant high potential.

The energy storage unit 20 can be a capacitor or a battery.

The LED lighting controller 30 may be a microprocessor or composed of an electric circuit. The LED light controller 30 can receive the ambient light value detected by the light sensing element 40 in real time, and then generate a PWM pulse wave to control the brightness of the LED chip 70 according to the value set by the user. In addition, the LED light controller 30 can receive the value of the air sensor 60 to detect the air measurement in real time, such as the concentration of carbon monoxide or carbon dioxide. When the value exceeds the value set by the user, the audible alarm 50 is activated, and Control the flashing of track lights to warn people in the illuminated space. The LED lighting controller 30 is provided with a module number, which can be pre-stored or selected by a dip switch for comparison with the control target transmitted by the external controller.

The light sensing element 40 is used to detect ambient light to automatically adjust the illumination brightness of the track light.

The audible alarm 50 and the gas sensor 60 are used to detect the ambient gas concentration. When the detected gas concentration reaches the set hazard value, the audible alarm 50 can be driven to sound Warn and control the track lights to flash.

The LED chip 70 receives commands from the LED light controller 30 and performs corresponding light control on the LED lights.

When the above components are combined in sequence, this application uses only two electrical wires 11a, 11b to connect the track light and the track light main controller. After the track light is connected, the two electrical wires 11a, 11b can obtain the working power supply. And under control, users can increase or decrease the number of lights at will, or change a variety of track lights as they like. In addition, they can detect the state of the environment, maintain stable light brightness and detect the concentration of harmful gases to ensure personal safety in the light area. Therefore, this creation has the following advantages and effects: 1. The number of track lights connected to the light track can be adjusted at will. 2. The brightness of each track light can be set by the user's control. 3. It can automatically adjust the ideal brightness for different environments to achieve the function of power saving. 4. It can detect the concentration of harmful gas, generate light and sound warning. 5. The time for turning on and turning off the lights can be preset and automatically switched on and off. 6.
