Problems solved by technology

However, the size of the power board is not large. Considering that each filament does not interfere with each other, it is often necessary to put on a sleeve, which makes the LED filament welding process very inconvenient, which is not conducive to mass production.

Abstract

The invention discloses a lamp bulb of an LED lamp filament structure. The lamp bulb comprises a lamp base, a core column, more than two LED lamp bars and a lampshade; the lampshade is fixedly connected with the lamp base; the more than two LED lamp bars and the core columns are sealed by the lampshade; more than two LED lamp bars are arranged to surround the core column; more than two electrodes are arranged on the core column; the two ends of each LED lamp bar are connected with one end of an electrode on the core column by virtue of butt-welding, respectively, and the other end of the electrode is connected with the lamp base and connected with an external AC or DC circuit by use of a lamp base; each LED lamp bar comprises a thread-like LED and an LED driving power source; the LED driving power source is connected in series with the thread-like LED and drives the thread-like LED to work. According to the lamp bulb structure, only the LED lamp bar is butt-welded on the electrode of the core column; as a result, the welding process is simplified and batch production can be realized.

Description

technical field [0001] The invention relates to an illuminating device, in particular to a light bulb with an LED filament structure. Background technique [0002] LED is a solid-state light-emitting device that uses the PN junction to emit light under the action of an electric field. It has the characteristics of high efficiency, environmental protection, and energy saving. It is a new green light source. At present, LED luminescence is produced by exciting yellow-green phosphors through blue chips and reconciling wavelengths. With the development and maturity of LED technology, LED light sources are gradually replacing incandescent lamps and fluorescent lamps. Therefore, light bulbs using LEDs as light sources appear. . [0003] The power supply board of the LED filament of the existing LED filament structure bulb is generally fixed in the lamp cap, and the multiple strings of LED filaments in the bulb are all welded to the power supply board and driven by the power suppl...
