Embodiment 1

[0027] Embodiment 1: Please refer to the attached image 3 , in the present embodiment, in order to utilize the switch to turn on the situation of LED light one by one, comprise the following steps during initialization:

[0028] A. The control unit first detects whether the control signal module has ID confirmation data sent;

[0029] B. If no ID confirmation data is sent, the control unit may be the first to start the light, and it is automatically set as the main control unit, and the main control unit automatically sets its own ID address to 1, and it is sorted in the address In the first place, and through the control signal module to send ID confirmation data to other control units in a continuous cycle; if there is ID confirmation data sent, it is confirmed that the control unit may be a rear-start lamp, which is a sub-control unit , at this time, the sub-control unit randomly generates an ID address (generated by a commonly used random number generation program), and ...

Embodiment 2

[0032] Embodiment two: Please refer to the attached Figure 4, in this embodiment, the general control switch is used to turn on all the LED lights together, that is, all the lights are initialized together. During initialization, when all the control units are started at the same time, each control unit generates a address, and send it to other control units; at the same time, it also receives the address with ID 1 sent by other control units. At this time, each control unit randomly generates an ID address and sends it to other control units. Each control unit sorts all addresses, the one with the smallest ID address is the main control unit, and the others are sub-control units, and returns the ID and sorting of each sub-control unit to each sub-control system for storage, and stores them in the main control unit at the same time , then the system is stable.

[0033] When the present invention is in use, each control unit is connected into a network by adopting a ring or b...

Abstract

The invention discloses a method for driving a light-emitting diode (LED), which can control a main circuit to light by using a software mode so as to reduce the wire quantity between the LED and a power supply; the method comprises a step of setting more than one relatively independent control unit, wherein each control unit comprises a central control module, a power supply module, a driven output module and a control signal module; the central control module outputs a control signal to control the driven output module; the driven output module drives a group of LEDs to light; the control signal module is interconnected with the control signal modules of other control units to transmit a control signal. According to the method, a special programmed algorithm is employed so that all LEDscan be controlled by one remote controller, and no conflict exists between the LEDs; besides, the wire quantity between the LEDs is reduced, and the wiring workload during installation of the LED is reduced so as to facilitate the use of the LED.

Description

technical field [0001] The invention discloses a driving method of a high-power white light LED, in particular an LED driving method capable of controlling the main circuit to emit light in a software manner, thereby reducing the number of connections between the LED and a power supply. Background technique [0002] As a new lighting device, LED has been widely promoted in the field of lighting. With the deepening of LED research, LED devices have gradually entered the field of daily household lighting. Since household lighting LEDs generally use high-power white light LEDs, and high-power white light LEDs are current-mode devices, it is particularly important to strictly control the magnitude of their current flow during use. Generally, LED lighting needs to meet three conditions: 1. The polarity between the LED and the power supply must be connected correctly; 2. The driving voltage of the LED must reach 1.7V (red LED) or 3.0V (blue, green, white or other colors) LED); 3....
