Abstract

A filament LED bulb relates to an LED lamp. The LED lamp is characterized by being assembled by a lamp holder, a lamp shade, a driving power supply, a lead, one or more circuit boards and a filament LED, wherein the driving power supply is arranged in the lamp holder, the lead connected with the output end of the driving power supply is connected in series with the one or more circuit boards, one or more filament LEDs are welded on each circuit board, and the one or more filament LEDs 1 form a series or parallel loop through a circuit on the circuit board; one or more circuit boards are connected in series through a lead to form a one-layer or multi-layer structure to form a tower-layer structure, so that a tower-layer light-emitting structure is formed and fixed in the lampshade; one end of the lampshade is configured with the lamp holder to form an LED bulb. Because no object covers the luminous surface of the filament LED1, when the lamp is powered on, the lead of the power supply output end is driven to conduct current to one or more circuit boards connected in series by the lead, and the filament on the circuit board is lightened to realize wide luminous angle.

Description

A filament LED light bulb

technical field

The invention relates to an LED lamp, in particular to a filament LED bulb with a wide light emitting angle.

Background technique

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.

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 the light board block the light, the light-emitting angle of the LED light bulb will be hindered and become smaller. , so most of the LED bulbs currently on sale have a light angle of less than 120 degrees, which is not as good as traditional light bulbs with a light angle of more than 300 degrees.

Contents of the invention

The present invention aims to overcome the influence of the shading of the radiator in the prior art, causing its light-emitting angle to be far smaller than that of traditional light bulbs with a wide light-emitting angle. It is manufactured with its narrow light-emitting angle in commercial lighting, industrial lighting and home lighting applications. The effect of the romantic atmosphere is not as good as the traditional light bulb with a wide light angle, so we provide a filament LED light bulb. The luminous angle of the filament LED light bulb is comparable to that of the traditional light bulb.

For this reason, a kind of filament LED bulb of the present invention adopts following two technical solutions:

One of the technical solutions

A filament LED light bulb assembled for:

Lamp;

Lampshade, one end of the lampshade is configured with the lamp holder;

The driving power is arranged in the lamp holder;

wire;

A circuit board for installing the filament LED is provided, and the circuit board is arranged in the lampshade; one circuit board is connected to the driving power supply through the wire;

Filament LED (also referred to as LED filament), the filament LED is in the shape of a long strip, installed on the circuit board, and the length direction of the filament LED is along the vertical direction of the board surface of the circuit board.

Further, a filament LED is installed on the circuit board, and the filament LED is welded to the circuit board.

Alternatively, multiple filament LEDs are welded on the circuit board, and the multiple filament LEDs are connected in series or in parallel.

The second technical solution:

A filament LED light bulb is composed of the following components:

Lamp;

Lampshade, one end of the opening of the lampshade is configured with the lamp holder;

The driving power is arranged in the lamp holder;

wire;

Set up a plurality of circuit boards for installing filament LEDs, and the circuit boards are arranged in the lampshade; the circuit boards of the plurality of pieces are connected in series and connected to the driving power supply through the wires; the circuit boards of the plurality of pieces are arranged in this way, and their adjacent The board surfaces of the circuit boards are arranged oppositely, and there is a certain distance between adjacent circuit boards;

Filament LED (also referred to as LED filament), the filament LED is in the shape of a long strip, installed on the circuit board, and the length direction of the filament LED is along the vertical direction of the board surface of the circuit board.

Further, a filament LED is installed on the circuit board, and the filament LED is welded to the circuit board.

Alternatively, multiple filament LEDs are welded on the circuit board, and the multiple filament LEDs are connected in series or in parallel.

The beneficial effect of the present invention is that

Firstly, one or more circuit boards are connected in series by the wires connected to the driving power supply, and one or more filament LEDs are welded on each circuit board, and the multiple circuit boards are arranged in tower layers to form a tower luminous structure. Since there is no object in the bulb to cover the light-emitting surface of the filament LED, the light-emitting angle can be as large as possible, such as more than 300 degrees, or even 360 degrees.

Second, it has a wide range of uses and is very suitable for commercial lighting, industrial lighting and home lighting. It can create a romantic atmosphere with its wide lighting angle, which is comparable to traditional light bulbs in this respect.

Detailed ways

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

As shown in Fig. 1 and Fig. 2, a kind of filament LED light bulb of the present invention, by filament LED1, circuit board 2-1, circuit board 2-2, circuit board 2-3, circuit board 2-4, drive power supply 3, wire 4-1, lead wire 4-2, lampshade 5 and lamp holder 6 are assembled. Place the driving power supply 3 in the lamp holder 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. Circuits on circuit board 2-2, circuit board 2-3 and circuit board 2-4 make one or more filament LED1 form a series or parallel circuit. One or more pieces of circuit board 2-1, circuit board 2-2, circuit board 2-3 and circuit board 2-4 are connected in series through wire 4-1 and wire 4-2 to form a structure of one or more layers and form a tower layer shape, forming a tower-like light-emitting structure and fixed inside the lampshade 5. One end of the lampshade 5 is configured with the lamp holder 6 to form an LED bulb. Because there is no object in the bulb to cover the light-emitting surface of the filament LED1, the wire 4-1 and the wire 4-2 at the output end of the drive power supply 3 conduct the current to one or more wires connected in series by the wire 4-1 and the wire 4-2 when the power is turned on. A circuit board 2-1, a circuit board 2-2, a circuit board 2-3, and a circuit board 2-4 are used to light the filament LED1 on the circuit board to achieve a wide light-emitting angle.

Filament LED1 is a strip-shaped LED packaged with a length of about 32 mm and a width of about 2 mm. It can be lit with an input DC voltage (positive and negative poles at the head and tail) of 50-80 volts, and the power of each filament is 0.5-1 watts. .
