Detachable decorative lamp

Abstract

The invention discloses a detachable decorative lamp, which comprises a modeling lamp body and a support with a ladder shape, wherein the support with a ladder shape comprises a horizontal branch and two vertical branches; both the horizontal branch and the two vertical branches consist of tubing lamps; both ends of the horizontal branch are provided with joints; the two vertical branches are provided with joints matched with the joints arranged at both ends of the horizontal branch; the hose lamp comprises an outer coating layer, core wires and a plurality of luminous units; the luminous units comprise a PCB, LEDs and a single-wire transmission drive control chip; and the single-wire transmission drive control chip inputs a control signal through a signal control circuit and directly drives and controls the LED to luminate. The detachable decorative lamp has the advantages of simple structure, diverse display colors of the lamp and good decorative effect.

Description

technical field [0001] The invention relates to a lighting device, in particular to a detachable decorative lamp. Background technique [0002] At present, the existing manufacturing method of decorative lamps is to bind the modeling lamp body on a rigid lamp frame, but it is inconvenient to fold, especially when the lamp frame is in the shape of a long ladder, it must be disassembled during packaging and transportation , and then install it when it is used, and the usual ladder-shaped light frame is composed of an iron frame and then the light body is bound on the light frame. Although the iron frame can be folded, the cost is high. Larger, so the weight is too heavy, and the light stand does not shine. If the light stand is fixed, the light stand can no longer be extended, and the size of the decorative lamp cannot be determined according to the actual decoration place.

Problems solved by technology

[0002] At present, the existing manufacturing method of decorative lamps is to bind the modeling lamp body on a rigid lamp frame, but it is inconvenient to fold, especially when the lamp frame is in the shape of a long ladder, it must be disassembled during packaging and transportation , and then install it when it is used, and the usual ladder-shaped light frame is composed of an iron frame and then the light body is bound on the light frame. Although the iron frame can be folded, the cost is high. Larger, so the weight is too heavy, and the light stand does not shine. If the light stand is fixed, the light stand can no longer be extended, and the size of the decorative lamp cannot be determined according to the actual decoration place. There are disadvantages of inconvenient use, and It brings inconvenience to packaging and transportation. Since the lamp holder does not shine, there must be some accessories that do not have a decorative effect during use, which will affect the decorative effect and the cost is high

Chinese patent CN2610222Y discloses a detachable decorative lamp. The bracket in the shape of a ladder includes two parts: a horizontal branch and two vertical branches. All are equipped with correspondingly connected joints, which basically solve the above problems, but because in this invention, the hose lamp does not have a built-in chip control, the change of the lamp is very simple

[0003] However, in the prior art, the drive control chip of the lighting decoration generally uses four signal control lines to form a transmission channel for control. One and one signal connector, so too many connectors will lead to an increase in failure rate and low reliability; cascade connection of four signals has a great limit on the size of the PCB board, and it is easy to cause a short circuit for a small PCB board , disconnection and other problems, the structure of the light-emitting unit in the lighting is complex; the signals of the four signal lines interfere with each other, resulting in a limited cascade length
