Simulated-tree festoon lighting structure

Abstract

The invention discloses a simulated-tree festoon lighting structure comprising a simulated trunk, simulated branches, simulated leaves and simulated flowers, wherein the simulated trunk and the simulated branches are respectively made by covering an insulated skin on a plurality of leads, each lead contains a power source anode circuit, a power source cathode circuit and a signal control circuit,wherein the simulated leaves and the simulated flowers are provided with luminescence units, and each luminescence unit comprises a PCB, an LED arranged on the PCB and a single-lead transmission driving control chip; the power source anode circuit is connected with the LED on the PCB, the power source cathode circuit is connected with the single-lead transmission driving control chip on the PCB; and the signal control circuit inputs a control signal to the single-lead transmission driving control chip which directly drives and controls the lightening of the LED. The invention has simple structure, various festoon lighting display changes and good decorative effect.

Description

technical field [0001] The invention relates to a lighting device, in particular to a simulated tree light structure. Background technique [0002] Imitation plant decorative lamps have been widely used to decorate homes or for municipal construction, but the common practice of existing simulated decorative tree lamps is to make simulated tree trunks with plastic, and then insert simulated branches and simulated leaves made of plastic into simulated tree trunks. On the trunk, but its decorative effect is poor, the cost is high, and it cannot be arbitrarily shaped according to the user's requirements. Chinese patent 200320118694.6 discloses a simulated tree lighting structure. The simulated tree trunk and simulated branches of this patent are directly made of several wires and covered with a skin, which has the advantage of being able to be shaped arbitrarily. However, because the simulated tree lighting structure does not have a built-in drive control chip, the brightness o...

AI Technical Summary

Problems solved by technology

However, since the simulated tree lighting structure does not have a built-in drive control chip, the brightness of the lamp can only be adjusted by the magnitude of the current, and the change of the lighting is very simple.

In the prior art, the drive control chips of lighting decorations generally use four signal control lines to form a transmission channel for control. When four lines are connected with flexible wires, there are generally two input heads, two output heads, power connectors and One signal connector each, 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 for a small PCB board, it is easy to cause a short circuit. 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
