Problems solved by technology

[0004] In the prior art, serial connections are used between chips, and the drive control chip has only one signal control line to transmit signals. When the signal control line is disconnected or other errors occur, it will seriously affect the devices connected to it. , resulting in no signal input to the chip connected to it, and the LED lamp body cannot work
[0005] In addition, because the LED lamp body of the existing hose lamp is fixed and sealed inside the plastic material, firstly, it is easy to cause poor heat dissipation, local overheating, and cause safety hazards; secondly, once the lamp body is damaged, it cannot be repaired and can only be replaced.

Embodiment 1

[0037] like figure 1 and figure 2 As shown, an LED hose lamp embedded with redundant fault-tolerant control chips includes a light-transmitting lamp tube 101, a flexible inner intestine 102, and a lamp body 105; the light-transmitting lamp tube 101 and the flexible inner intestine can be made of thermoplastic flame-retardant insulating plastic PVC, light-transmitting lamp tube 101 is hermetically wrapped outside the flexible inner intestine 102, and a cavity 103 is arranged inside the flexible inner intestine 102. In this embodiment, the shape of the cavity is semicircular, and other shapes such as rectangle, triangle, etc. can also be used. The body 105 is placed inside the cavity 103 of the flexible inner intestine 102, and the lamp body includes: a flexible PCB board, an LED light-emitting unit arranged on the flexible PCB board, a chip arranged on the flexible PCB board to control the light emission of the LED light-emitting unit; the LED unit Including at least one LED ...

Embodiment 2

[0042] like figure 2Shown is a cascaded structure of hose lights embedded with redundant fault-tolerant chips in the application. The chip has two parallel signal input terminals and two parallel signal output terminals. The two signal input terminals are used for cascading The input of the cascade control signal 1 and the cascade control signal 2, the two signal output ports are used for the output of the cascade control signal 1 and the cascade control signal 2, the chip provides two identical signal control by two lines with opposite transmission directions The lines are respectively used to transmit the cascade control signal 1 and the cascade control signal 2; the LED light-emitting unit is composed of a red light-emitting diode R, a green light-emitting diode G, and a blue light-emitting diode B, which are connected in series with R1, R2, and R3 respectively; the positive pole of the power supply Line VCC and power supply negative line GND provide voltage to the circuit...

Embodiment 3

[0044] See image 3 , the difference from Embodiment 2 is that a dedicated constant current drive chip is integrated on the internal PCB of the hose lamp, and the constant current drive chip is connected to the local output terminal of the redundant fault-tolerant control chip, and the output terminal is connected to the cathode of the LED lamp through a series resistor , through the constant current drive chip, according to the local output data, complete the drive of the LED lamp, and control the change of the LED light and shade. The advantage of using a dedicated driver chip is that the driving current is convenient to control, the work is stable, and the display effect is better.

Abstract

The invention discloses an LED hose lamp embedded with a redundancy fault-tolerant control chip, which comprises a flexible light-transmitting light tube and a lamp body, wherein a flexible PCB board is arranged in the lamp body; an LED luminescent unit arranged on the flexible PCB board comprises at least one LED lamp, and the chip controls the luminescence of the LED luminescent unit; the redundancy fault-tolerant control chip is provided with at least two signal input ends, signal output ends with the same number as the signal input ends, at least one local output end and an arbitration module; at least two cascade channels are arranged through the signal input ends and the signal output ends, and the arbitration module is used for judging the effectiveness of the cascade channels and takes output of effective cascade channels as output of ineffective cascade channels; and the local output end is connected to the LED luminescent unit and is used for controlling the luminescence of the LED luminescent unit. The redundancy chip is adopted to reduce the failure rate and contribute to the maintenance of the hose lamp.

Description

technical field [0001] The invention relates to an application of LED display, in particular to an LED hose lamp embedded with a redundant fault-tolerant control chip. Background technique [0002] At present, the LED hose lights widely used in the market are generally: three colors of light-emitting diodes R, G, and B (R is a red light-emitting diode, B is a blue light-emitting diode, and G is a green light-emitting diode) as The basic unit of a light-emitting point, that is, a pixel, is formed into a hose lamp by plastic sealing and potting. Then use R, G, B hose lamps as basic units to form patterns to realize night scene decoration, or form an LED display to complete the display function. [0003] The prior art mainly has the following shortcoming: [0004] In the prior art, serial connections are used between chips, and the drive control chip has only one signal control line to transmit signals. When the signal control line is disconnected or other errors occur, it wi...
