Ultrathin flexible neon lamp integrated with single-wire transmission control chip

Abstract

The invention discloses an ultrathin flexible neon lamp integrated with a single-wire transmission control chip, which comprises a flexible non-light tight core wire, an LED lamp string arranged in the core wire, a flexible non-light tight coating layer coated outside the core wire, a flexible non-light tight light diffuser arranged above the core wire and having equal length with the core wire, and a flexible light shielding layer positioned on two sides of the core wire on the lower part of the coating layer, wherein the LED lamp string consists of a plurality of display units which are connected with one another through power supply positive and negative electrode circuits and a signal control circuit; and a lighting transmission drive control chip is a single-wire transmission drive control chip which inputs control signals through the signal control circuit and directly drives and controls the LED of the display units to emit light. The lamp body of the ultrathin flexible neon lamp is thin, has better flexibility and is easier for bending modeling.

Description

technical field [0001] The invention relates to a lighting device, in particular to an ultra-thin flexible neon lamp integrating a single-wire transmission control chip. Background technique [0002] Chinese Patent No. 200610123841.7 "An Ultra-thin Flexible Neon Lamp" discloses an ultra-thin flexible neon lamp comprising a flexible light-transmitting core wire, an LED light string arranged inside the core wire, and an A flexible light-transmitting coating layer, a flexible light-transmitting astigmatism arranged above the core wire and having the same length as the core wire, a flexible light-shielding layer located on both sides of the core wire under the coating layer, which does not contain lighting drive control chips, and cannot Effectively control the light emission of LED light-emitting diodes; even if some ultra-thin flexible neon lights contain lighting driver control chips, these driver control chips generally require four control signal lines, so when connected wi...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the control signal circuit of the ultra-thin flexible neon lamp is complex, and the number of joints is large, resulting in a high joint failure rate and low reliability, and the size of the PCB board and the length of the cascade are greatly limited
