Embodiment Construction

[0032] The specific implementation manner of the present invention will be introduced below in conjunction with the accompanying drawings.

[0033] Such as figure 1 and figure 2 As shown, a filament LED light bulb of the present invention is composed of a filament LED1, a circuit board 2-1, a circuit board 2-2, a circuit board 2-3, a circuit board 2-4, a driving power supply 3, a wire 4-1, and a wire 4 -2. The lampshade 5 and lamp holder 6 are assembled. Place the driving power supply 3 in the lamp cap 6, connect one or more circuit boards 2-1, circuit board 2-2, and circuit board 2 in series with the wire 4-1 and wire 4-2 connected to the output end of the driving power supply 3 -3 and circuit board 2-4, one or more filament LED1 is welded on each circuit board 2-1, circuit board 2-2, circuit board 2-3 and circuit board 2-4, through circuit board 2- 1. The circuits on the circuit board 2-2, the circuit board 2-3 and the circuit board 2-4 make one or more filament LED1 for...

Abstract

The invention discloses a lamp filament LED (Light-Emitting Diode) bulb, and relates to an LED lamp. The lamp filament LED bulb is assembled by using a lamp cap, a lampshade, a driving power supply, leads, one or more circuit boards and filament LEDs, wherein the driving power supply is arranged in the lamp cap; the leads for connecting the output end of the driving power supply are connected in series with one or more circuit boards; one or more filament LEDs are welded on each circuit board; through a circuit on each circuit board, one or more filament LED1 form a serial or parallel loop; one or more circuit boards are connected in series into a single-layer or multi-layer structure through the leads, and are constructed into tower layer; a tower-layer-shaped light-emitting structure is formed, and is fixed inside the lampshade; one end of the lampshade is configured together with the lamp cap into an LED bulb. The light-emitting surface of each filament LED1 is not shielded by any object in the bulb. In a switch-on state, current is conducted onto one or more circuit boards which are connected in series through the leads by using the leads at the output end of the driving power supply, and filaments on the circuit boards are lightened to realize a wider light-emitting angle.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a filament LED bulb with a wide light emitting angle. Background technique [0002] Light bulbs made of LEDs have the advantages of low power consumption, low heat generation, and long service life, and have been widely used in various fields. However, the light-emitting angle of the existing LED light bulbs is much smaller than that of traditional light bulbs with wide light-emitting angles. In the application of commercial lighting, industrial lighting and home lighting, in addition to energy saving and carbon reduction, with the current narrow lighting angle of commercially available LED bulbs, if you want to use light to create a romantic scene effect, it is still not as good as the wide lighting angle. Traditional light bulb. [0003] The known LED light bulbs include a heat sink with different shapes and sizes, and the LED light board is attached to the heat sink. Because the heat sink and ...
