Abstract

The invention discloses an LED lamp filament, a manufacturing method of the LED lamp filament and light source equipment. The LED lamp filament comprises an LED assembly; a rectifying circuit coupled with the positive electrode and the negative electrode of the LED assembly and an external power supply, and used for rectifying the alternating current applied to the positive electrode and the negative electrode of the LED assembly so as to provide direct current for the LED assembly. Through the above mode, the LED lamp filament can work under alternating current, and the use scene of the LED lamp filament is increased.

Description

technical field [0001] The present application relates to the technical field of lighting, in particular to an LED filament, a manufacturing method thereof, and a light source device. Background technique [0002] LEDs (Light Emitting Diodes, light emitting diodes) are made of compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and the like. Visible light can be radiated when electrons and holes recombine, so they can be used to make light-emitting diodes. LEDs are generally used as indicator lights in circuits and instruments, or to form text or digital displays, and are also used as lighting equipment. [0003] However, due to the characteristics of LEDs, only DC power can be passed through, and AC power cannot be used directly, which limits the application fields of LEDs. Contents of the invention [0004] In order to solve the above problems, the present application provides an LED filament, a manufacturing method thereof, and a light source...
