LED molding decoration lamp

Abstract

The invention discloses an LED molding decoration lamp. The lamp comprises a strip model, an illuminant which is arranged on the strip model, a transparent support layer which is arranged between profiles of the strip model, and a model coating layer which is arranged outside the transparent support layer, wherein the illuminant comprises a PCB board and illumination units which are arranged on the PCB board; the illumination unit comprises an LED and a single-wire transmission drive control chip; the single-wire transmission drive control chip inputs a control signal through a signal controlcircuit to directly drive and control the LED to emit light; and the illumination units are electrically connected in parallel through a power supply anode circuit and a power supply cathode circuit,and are connected in series through a signal control circuit. The decoration lamp has the characteristics of simple structure, various changes in LED illumination modes and good decoration effect.

Description

technical field [0001] The invention relates to a lighting device, in particular to an LED decorative lamp. Background technique [0002] In Western Christmas, various traditional Christmas decorative lights shapes, such as reindeer, Christmas tree, Santa Claus, snowman, and gift boxes, are usually made in the following ways. The first type of modeling decorative lamp is composed of plates with a main decorative outline. The plates of this type of products are not transparent materials and cannot transmit light. The second type of modeling decorative lights is composed of ropes, skeletons, and iron wires. Since these products are connected by iron wires or plastic strips, they can form three-dimensional patterns, but the whole only reflects the three-dimensional shape of the skeleton. For example, animal shapes only reflect Without the skeleton, the texture of the skin is lacking, it is difficult to achieve a realistic effect, and the decorative effect is not good. Chinese...

Problems solved by technology

The second type of modeling decorative lights is composed of ropes, skeletons, and iron wires. Since these products are connected by iron wires or plastic strips, they can form three-dimensional patterns, but the whole only reflects the three-dimensional shape of the skeleton. For example, animal shapes only reflect The skeleton is missing, the texture of the skin is lacking, it is difficult to achieve a realistic effect, and the decorative effect is not good

But because there is no control chip in the decorative lamp, the brightness of the lamp can only be controlled by changing the magnitude of the current, the color displayed by the lamp is very single, and the decorative effect is still not good enough

[0003] In the prior art, each LED can be individually controlled by a built-in drive control chip, so that the decorative lights can be varied and the decorative effect is good. However, the drive control chips of the lighting decorations in the prior art 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, one power connector and one signal connector, so too many connectors will lead to an increase in failure rate and low reliability; four The cascading of signals has a great limit on the size of the PCB board. For small PCB boards, it is easy to cause problems such as short circuit and disconnection. The structure of the light-emitting unit in the lighting is complicated; the signals of the four signal lines interfere with each other. Cascading to a finite length
