Internal control type LED (light-emitting diode) nixie tube system and control method thereof

Abstract

The invention provides an internal control type LED (light-emitting diode) nixie tube system and a control method thereof; the internal control type LED (light-emitting diode) nixie tube system can be freely installed according to actual requirements during engineering construction without an external controller under the condition that a demonstrating control program of each nixie tube is not burned in advance before leaving factory, and the code of each nixie tube is identified in advance; a user can update the demonstrating contents of the nixie tubes at any time; when the system works, each nixie tube can be independent of the system or keep pace with the system; and during maintenance, the nixie tubes at different positions can be used interchangeably. The internal control type LED (light-emitting diode) nixie tube system comprises a computer controller, a data converter and more than one internal controls units, wherein the computer controller comprises an LED (light-emitting diode) mapping dot matrix data module and a demonstrating control data module; each internal control unit comprises more than one group of LED (light-emitting diode) luminous elements, an LED (light-emitting diode) driving unit, a microprogrammed control unit (MCU) and a storage; the LED (light-emitting diode) driving unit is used for driving the LED (light-emitting diode) luminous elements; the microprogrammed control unit (MCU) is used for controlling data communication and the luminescence of the LED (light-emitting diode) through the LED (light-emitting diode) driving unit; and the storage provides a demonstrating control identification signal to be received and read by the microprogrammed control unit (MCU).

Description

technical field [0001] The invention belongs to the technical field of LED landscape and decorative lighting applications, and in particular relates to an internal control type LED digital tube system and a control method thereof. Background technique [0002] Common LED landscape decorative lights include guardrail tubes, soft light strips, pixel lights, wall washers, etc., which are widely used in landscape lighting and building decoration. Color LED guardrail tube, also known as LED digital tube, has been widely used in various occasions such as building outline, bridge road decoration lighting, RGB guardrail tube light screen, full-color digital signboard and so on. Existing LED digital tubes mainly use external control type control methods, and a small number of them use internal control type control methods. [0003] The externally controlled LED digital tube needs to be connected with an expensive external controller when demonstrating work. For example, the Chinese ...

AI Technical Summary

Problems solved by technology

It can be seen that the traditional internal control digital tube has problems such as inflexibility in practical application, easy confusion in on-site installation and inconvenient maintenance, so these two kinds of guardrail tube products have inherent defects and deficiencies in the existing technology
