Embodiment 1

[0023] Example 1, such as figure 1 and figure 2 Shown: a control method suitable for LED lamps with different pixels, including the following steps:

[0024] 1) Connection steps: Connect multiple control terminals to one main control terminal, each control terminal is connected to multiple LED lights through a data bus, each of the LED lights is only connected to one of the data buses, at this time The pixel point of each LED lamp is set as a node, and the LED lamp and the control terminal adopt a two-way communication method, and the control terminal can receive the information from the pixel point Data feedback, so that when the communication failure or the number of pixels exceeds the controllable upper limit of the control terminal, the user can observe it, which is convenient for troubleshooting. On the other hand, it is not an LED light that is set as a node , but use a single pixel as a separate address node, which provides the possibility for mixed operation of LED ...

Abstract

The invention relates to the field of lighting equipment, in particular to a control method suitable for LED lamps with different pixels. According to the technical scheme, the control method suitable for the LED lamps with the different pixels comprises the step of connection, the step of setting, the step of address frame sending, the step of full capacity checking, the step of inquiry frame sending and the step of feedback. The control method suitable for the LED lamps with the different pixels can solve the problem that in the prior art, address allocation can only be conducted on lamps with the same number of channels. A control end can known the serial numbers of the lamps failing to work when a communication failure or a repeat address occurs, and troubleshooting is carried out conveniently.

Description

technical field [0001] The invention relates to the field of lighting equipment, in particular to a control method suitable for LED lamps with different pixels. Background technique [0002] As a lighting device with low energy consumption, high luminous efficiency and small size, LED has been widely used in recent years and is frequently used in various urban lighting projects. In use, a lighting device often includes a plurality of mutually independent LED lamps, which need to cooperate with each other to form a personalized lighting effect, which requires a control terminal to effectively control these multiple LED lamps. [0003] The patent document with the notification number CN 102448219 A discloses a control system for LED lamps, including a console, a plurality of master station LED lamps connected to the console and slave station LED lamps connected to the master station LED lamps. This method is also widely used in the industry, but this control method has two de...
