Abstract

The invention discloses an LED pixel lamp with redundancy fault-tolerant function and a lamp screen consisting of the same. The LED pixel lamp consists of a lamp shell and a lamp body; the inside of the lamp body is provided with a PCB board provided with an LED luminous unit, a driving control chip and power supply anode-cathode lines; the driving control chip at least comprises one redundancy fault-tolerant driving control chip provided with at least two pairs of signal input ends and signal output ends which are arranged in parallel; for each pair of signal input end and signal output end, the signal input end is connected with the signal output end by a line; the redundancy fault-tolerant driving control chips are connected with each other by at least two signal control lines which are arranged in parallel, have the redundancy fault-tolerant function and are provided by at least two lines; and a plurality of LED pixel lamps are in inserting connection by males and females arranged on end parts of the lines to form the LED pixel lamp screen.

Description

technical field [0001] The invention relates to the field of lighting displays, in particular to a pixel light and a light screen composed of the same. Background technique [0002] The most widely used is the large-area integral electronic display board. Due to the inconvenience of disassembly, transportation, installation, and maintenance, it is likely to be replaced by small pixel lights, because small pixel lights can be composed of various areas according to needs. Screens of various shapes can also form a display with several pixel lights to display various videos, animations, etc. Since the LED screen has the characteristics of many components, many connections, many power supplies, complex circuits, and many components, it is necessary to have a very high reliability of the system to ensure that there are no problems. However, under the current engineering technology level, the task of stable operation depends entirely on the investment in the selection of component...
