Problems solved by technology

[0010] Such a structure is complicated, the implementation cost is high, and it is also affected by the bypass of the power line to the ground. In particular, the modulation and demodulation equipment of the subcarrier is expensive, so it is not easy to operate in real situations, and it cannot be promoted at present.

Embodiment

[0028] A two-wire light control system based on energy storage, such as figure 1 As shown: it includes a controllable power supply circuit 1 and multiple lamp units 2, and each lamp unit 2 broadcasts and receives binary control commands from the controllable power supply circuit 1, so that the LED light source 28 can change its work according to the binary control commands State, only two wires are used to transmit energy and also transmit control information to each lamp unit 2, and the energy storage circuit 23 provides enough electric energy to the LED light source 28 when the voltage is temporarily lost.

[0029] Each lamp unit 2 contains an energy storage circuit 23 .

[0030] Each lamp unit 2 includes a zero-level sampling circuit, and the zero-level sampling circuit includes a voltage sampling circuit 25 and a one-way path 22, which can ensure that the characteristic value of the short circuit break required is obtained from the power line under any circumstances.

Abstract

The invention belongs to the technical field of landscape lighting, and relates to a bi-wire lamp control system based on an energy storage method. The bi-wire lamp control system based on the energy storage method comprises a controllable power supply circuit and a plurality of lamp units, each lamp circuit receives a binary control command from the controllable power supply circuit in a broadcast mode, therefore, a light-emitting diode (LED) light source can change working condition according to the binary control command, only two wires are used for transmitting energy and transmitting control information to each lamp unit at the same time, and a tank circuit supplies enough electric energy to the LED light source when voltage is absent temporarily. The bi-wire lamp control system based on the energy storage method has an energy storage function, even a power line is interrupted, the power supply of an LED lamp is not influenced, information can be obtained from the power line, and then the color of each lamp can be controlled to be changed. Further, wiring is simple, cost is reduced greatly, and accordingly majority of defects of an LED lighting system are overcome. In addition, the bi-wire lamp control system based on the energy storage method has good application prospects in the technical field of landscape lighting.

Description

technical field [0001] The invention belongs to the technical field of lighting control and relates to a two-wire lighting control system based on energy storage. Background technique [0002] LED lighting has gone through more than ten years in the field of lighting control technology, and its control technology has also developed in several stages. Many problems have been solved in each stage, and at the same time, new problems have been introduced. The following is a further discussion on the development of LED control technology. [0003] In the first stage, the way the LED display drive control mode is transferred. [0004] Using the serial shift communication method, each chip is cascaded, and each lamp is cascaded. Among them, there are both constant voltage driving methods and constant current driving methods. The problem caused by this communication method is that there are too many signal lines on the lamps, reaching 4 or 5 (including ground wires), and the time...
