Embodiment Construction
[0016] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0017] The flicker control method and system for LED light strings provided by the embodiments of the present invention store multiple display modes in advance (that is, pattern flashing methods), then set a display sequence for the driver chip, and finally drive each group of LED light strings in combination with the display sequence in accordance with the display sequence. The sequence flashes according to the corresponding display mode, realizing the effect of flowing water flashing or moving flashing of multiple groups of LED light strings, and the control m...

The invention belongs to the technical field of LED lamp control and provides an LED lamp string scintillation control method and system. The system comprises multiple groups of LED lamp strings and at least one drive chip, and the multiple groups of LED lamp strings are connected with the at least one drive chip. The scintillation control method comprises the following steps of storing a plurality of display modes in advance, setting a display sequence to the drive chip, and sequentially displaying each group of LED lamp strings in accordance with the display mode corresponding to the display sequence. With the combination of each group of LED lamp strings with the display sequence, and in accordance with the display mode for scintillation, the effect of one-by-one flash, mobile flash or random flash of the multiple groups of LED lamp strings is achieved. The control method is easy to implement, and the problem that nonsynchronous patterns such as one-by-one flash and mobile flash of multiple groups of LED lamp strings cannot be achieved by the conventional LED lamp string scintillation control technology is solved.
Description
technical field [0001] The invention belongs to the technical field of LED lamp control, and in particular relates to a flicker control method and system for an LED lamp string. Background technique [0002] In recent years, due to the advantages of energy saving and environmental protection, the development of LED lamps in the lighting industry has become a major trend. LED lights are widely used in indicating light sources of instruments, traffic lights, large-area display screens, car lights, keychain micro torches, billboards, urban lighting projects, architectural decoration, Christmas and other holiday lights. The wide application of LED lights has brought more requirements to the control of flashing methods. For example, when applied to the indicating light source of instruments and meters, different flashing methods need to be presented according to the different states of the instruments to remind the operator; LED light strings for stage lighting in entertainment ...
