Problems solved by technology

The structure of installing the drive power supply inside the LED lamp will cause high cost problems for the manufacturer, and there will be troublesome installation and long installation time during production. For the user, the LED lamp with the drive power supply is relatively small Large, the installation takes up a lot of space, and the overall appearance is not beautiful
In addition, due to the configuration of the driving power supply, the driving power supply is easily damaged by static electricity, so the working reliability and lifespan of this LED lamp cannot be guaranteed.

Abstract

The invention discloses an alternating current LED light source which comprises an LED lamp body, an alternating current power supply terminal and a light emitting component. The light emitting component comprises a first LED branch circuit, a second LED branch circuit and a third LED branch circuit; one terminal of the anode of the first LED branch circuit and one terminal of the anode of the second LED branch circuit are connected with one terminal of the cathode of the third LED branch circuit; one terminal of the cathode of the first LED branch circuit and one terminal of the cathode of the second LED branch circuit are connected with one terminal of the anode of the third LED branch circuit; one output terminal of the alternating current power supply terminal is connected with a cascade loop between two LED crystal grains of the first LED branch circuit; and the other output terminal of the alternating current power supply terminal is connected with a cascade loop between two LED crystal grains of the second LED branch circuit. The alternating current LED light source can be directly operated under a low-voltage alternating current power supply, is not internally provided with a driving power supply, and can greatly save material cost and manual installation cost, so that the volume is greatly reduced, and the occupied space is reduced during installation.

Description

technical field [0001] The invention relates to LED lighting technology, in particular to an AC LED light source which can be directly powered by AC. Background technique [0002] Traditional LED lamps are powered by DC. To enable them to work directly under AC, the current method is to configure a driving power supply inside the lamp body to convert the input AC power into DC power for the LED to work. The structure of installing the drive power supply inside the LED lamp will cause high cost problems for the manufacturer, and there will be troublesome installation and long installation time during production. For the user, the LED lamp with the drive power supply is relatively small Large, the installation takes up a lot of space, and the overall appearance is not beautiful. In addition, since the driving power is provided, the driving power is easily damaged by static electricity, so the working reliability and lifespan of this LED lamp cannot be guaranteed.
