LED guardrail tube and LED guardrail tube light screen consisting of same

Abstract

The invention discloses an LED guardrail tube and an LED guardrail tube light screen consisting of the same. The LED guardrail tube comprises a power positive line, a power negative line, a light-transmission casing and a PCB board, wherein the power positive and negative lines, a plurality of LED light-emitting units and a plurality of driving chips are arranged on the PCB board, the LED guardrail tube further comprises a single-wire transmission control chip, the chip inputs a control signal through a signal control line to control the driving chips on the PCB board, and then the driving chips directly drive the LED light-emitting units to emit light; and a plurality of the LED guardrail tubes are mutually connected through an end part to form an LED guardrail tube light screen. The LED guardrail tube has the advantages of simple structure, various connection forms, flexible installation and convenient maintenance; and the LED guardrail tube light screen is arranged into a comb shape or fishbone shape, therefore, the brightness and the refreshing frequency of the light screen can be improved within a certain area to achieve the effect of excellent display.

Description

Technical field [0001] The invention relates to an LED lamp tube and a lamp screen composed of the LED lamp tube, in particular to an LED guardrail tube and the LED guardrail tube lamp screen composed of the LED lamp tube. Background technique [0002] At present, LED guardrail tubes have been widely used in landscape lighting, building lighting, advertising signs and other occasions, playing an excellent beautifying effect. In the prior art, the guardrail tubes are connected in serial from end to end, and the guardrail tubes are usually serially cascaded through four signal lines. This connection method greatly limits the use of LED guardrail tubes as a display surface. Application: The guardrail tubes are cascaded through four signal wires, and the power and ground wires need to be cascaded with six wires. Because there are too many connectors in the line, the reliability is not high, and the restrictions on the PCB board are relatively large. If you want to connect the gu...

Problems solved by technology

In the prior art, the guardrail tubes are connected in series from end to end, and the guardrail tubes are generally cascaded through four signal lines in series. This connection method greatly limits the use of LED guardrail tubes as a display surface. Application: The guardrail tubes are cascaded through four signal wires, and the power and ground wires need to be cascaded with six wires. Because there are too many connectors in the line, the reliability is not high, and the restrictions on the PCB board are relatively large. If you want to connect the guardrail The wire coming out of the end of the pipe is pulled to the front so that it can be connected to each other at one end, which will make the circuit very complicated and difficult to route; When there is an error in the driver chip in the root guardrail tube, it will cause the guardrail tubes connected behind to fail to work normally.
