Abstract

Embodiments of the invention provide an LED string lamp comprising a power supply circuit, a control circuit and a plurality of LED lamp groups connected in series successively. The power supply circuit is used for using AC power to output a direct current of a preset voltage. The control circuit is connected with a power output terminal of the power supply circuit and is provided with an output terminal for outputting the direct current and a preset control signal, the output terminal comprising an output terminal positive electrode and an output terminal negative electrode. Each LED lamp group comprises a driving chip, a Zener diode and a plurality of color LEDs, the driving chip is provided with a power supply terminal, a ground terminal, and a plurality of driving terminals the number of which is matched with the number of the color LEDs. The negative electrode of the Zener diode is connected with the power supply terminal, and the positive electrode is connected with the ground terminal. The driving terminals are respectively connected with the color LEDs. The driving chip is used to drive the plurality of color LEDs to be on or off according to the control signal. As any of the LED lamp groups is connected with the control circuit only through the Zener diodes of the other lamp groups, thus the LED string lamp solves the problem that conventional LED string lamps are not reliable.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an LED string light. Background technique [0002] Lantern is a kind of traditional folk handicraft originated in China. In ancient times, its main function was lighting. Paper or silk was used as the outer skin of the lantern. The skeleton was usually made of bamboo or wooden strips, and candles or light bulbs were placed in the middle to become lighting tools. Influenced by Chinese culture, lanterns are also quite common items in temples in many countries in Asian Chinese regions. It rewards the gods and entertains people. It not only has the function of "Nuo opera" to reward the gods, but also has the value of entertaining people. In modern society, it is hung more than the Spring Festival, Lantern Festival and other festivals, adding luster to the festival and praying for peace. [0003] With the development of science and technology, traditional lanterns have become a comp...
