Description

Two-way power line LED light control system

The present invention relates to an LED lamp, and more particularly to a bidirectional power line LED lamp control system.

Recently, due to the interaction between the energy crisis and the health trend, green technology has become one of the hottest industries. Among them, the high-profile LED (Light Emitting Diode) lamp is very suitable for lighting equipment with 40% of global power consumption due to its low power consumption, high brightness and long life. element.

For example, 10 of the Energy ENERGY programs promoted by the US Environmental Protection Agency include three lighting devices: Energy Star Green Lights Program and Energy Star Emergency Exit Lighting Solution (Energy). Star Exit Signs Program) and the Energy Star Residential Light Fixtures Program. The attention paid to lighting equipment is visible.

However, in order to make LED lamps more energy efficient, environmental factors and heat dissipation performance must be considered. Therefore, the traditional control method only uses the switching of the power supply to perform the simple opening and closing of the lamps, or the switching of the power supply to switch the lamps in multiple stages to control the opening and closing of different lamps, which seems to be unable to meet the requirements of the LED lamps. Control demand. That is to say, for the control of the LED lamp, the same part also includes controlling its driving current to control its brightness and energy consumption, and even performing various control actions, etc., which have become the development space of future smart LED lamps.

To achieve the above control of smart LED luminaires, existing technologies must add a set of control lines alongside the power line to meet a variety of control needs. If the smart LED luminaires are installed synchronously in a new building, the cost of the control line will be incurred. If the smart luminaire is installed in an old building, in addition to the cost of controlling the line, the control line must be additionally routed, and the wiring cost is also required.

Similarly, when LED luminaires are used in street lighting systems, they also have the same wiring problems. The increase of this control line, in addition to the problem of increased cost, does not meet the basic requirements of green technology. Therefore, how to use more streamlined technology, without the use of control lines, can realize the wisdom of LED lamps at low cost, when it can be used as a model of green technology.

In view of the above problems in the prior art, the present invention provides a bidirectional power line LED lamp control system for controlling a plurality of LED modules and a plurality of sensors by transmitting a control signal and a sensing signal through a power line. The control system comprises: a control transceiver, a plurality of transceivers and a control panel. The control transceiver has a control coupling capacitor coupled to the power line for adjusting the control signal to the first modulation frequency at the first modulation frequency, and controlling the coupling capacitor to pass the first modulation signal to the power supply line. The second modulation signal with the sensing signal carried on the power line is captured and controlled by the coupling capacitor to be demodulated to a sensing signal at the second modulation frequency. Each transceiver has a transceiver coupling capacitor coupled to the power line and is coupled to the at least one LED module and the at least one sensor for receiving the first modulation signal via the transceiver coupling capacitor and demodulating at the first modulation frequency The control signal controls the LED module, and the sensing signal of the connected sensor is modulated into a second modulation signal at a second modulation frequency and transmitted through the transceiver coupling capacitor. The control panel is connected to the control transceiver for enabling the control transceiver to transmit and receive signals.

The above and other objects, features and advantages of the present invention will become more apparent and understood.

The invention uses a power cord as a transmission line for the LED light control system. The impedance of the power cord is not designed for transmission lines, especially in existing buildings or street lighting systems. Therefore, the impedance matching problem needs to be noted. In order to solve this problem, the present invention uses a coupling capacitor interface as a signal for transmitting a frequency to an LED lamp, which can adapt to the impedance problem of different power lines. The principle is that when the power line is regarded as a transmission line, regardless of the impedance value, when the coupling capacitor interface is added to one end of the power line, the entire power line and the coupling capacitor are integrated into a capacitive coupling body. Since the capacitor can transmit an AC signal, the capacitive coupler will transmit the signal through the power line to the LED fixture.
