Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a dimming structure for LED filaments. Background Technology

[0002] LED filament is a new type of LED packaging. By improving the structure of traditional LED beads, it achieves 360° omnidirectional light emission and can form a three-dimensional light source without the need for additional lenses. It can be applied to LED lighting products such as crystal chandeliers, candle lamps, bulb lamps, and wall lamps.

[0003] In order to improve the performance of lamps, existing filaments often combine two or more completely independent filaments of different colors. By supplying power to the different colored filaments separately, different colors of light can be adjusted. Therefore, two completely independent power supply lines are set at the connection point with the filaments, and multiple power supplies are needed to control the filaments, which makes the process quite difficult.

There are two sets of pins, and the resistor blocks are electrically connected to the pins. The pins are electrically connected to the first filament circuit and the second filament circuit on the substrate.

[0006] As a further preferred embodiment of this technical solution, the resistor blocks are electrically connected to each other with resistance wires, and the resistor blocks at the ends are electrically connected to power input lines. Inside the mounting bracket, a first connecting spring is provided at the middle position of the top of several resistor blocks. An electrode post is fixedly installed on the top of each resistor block, and the first connecting spring is electrically connected to the electrode post.

[0007] As a further preferred embodiment of this technical solution, a first motor is fixedly installed on the top of the mounting bracket, and a first fixing post is fixedly installed through the mounting bracket at the output end of the first motor. The first connecting spring is welded and fixed to the first fixing post.

[0008] As a further preferred embodiment of this technical solution, the pin includes a selection pin and a fixed pin, both of which are fixedly mounted on the bottom inner wall of the mounting bracket. The selection pin and the fixed pin are electrically connected to the wiring terminals of the first filament circuit and the second filament circuit, respectively.

The resistor blocks 5 are electrically connected to the pins 6, and the pins 6 are electrically connected to the first filament circuit 2 and the second filament circuit 3 on the substrate 1. A controller 11 is fixedly mounted on the top of the mounting bracket 4. The controller 11 is electrically connected to... The wireless signal receiver can transmit control signals via wireless communication technologies such as Bluetooth and Wi-Fi. Users can remotely control the lighting using an APP or a remote control. Users can also remotely transmit control signals to the controller 11 via an APP or a remote control. The controller 11 control circuit is electrically connected to one of the selection pins 14 on the two sets of pins 6 to form a closed circuit, which can control the lighting of the first filament circuit 2 or the second filament circuit 3. Different light levels can be selected. By controlling the number of resistor blocks 5 used, the resistance coefficient in the connected circuit can be adjusted, thereby adjusting the light intensity of the first filament circuit 2 or the second filament circuit 3.

[0021] like Figures 1 to 3 As shown, several resistor blocks 5 are electrically connected by resistor wires 7, and the end resistor blocks 5 are electrically connected by power input lines 8. The mounting bracket 4 is provided with a first connecting spring 9 at the middle position of the top of several resistor blocks 5. An electrode post 10 is fixedly installed on the top of the resistor block 5, and the first connecting spring 9 is electrically connected to the electrode post 10.

[0022] By controlling the connection between the first connecting spring 9 and the top electrode post 10 of the resistor block 5 at different positions, the resistance coefficient in the connected circuit can be adjusted.

[0023] like Figures 1 to 3 As shown, a first motor 12 is fixedly installed on the top of the mounting frame 4, and a first fixing post 13 is fixedly installed through the mounting frame 4 at the output end of the first motor 12. The first connecting spring 9 is welded and fixed to the first fixing post 13.

[0024] The first motor 12 drives the first connecting spring 9 to rotate, which can control the connection between the first connecting spring 9 and the top electrode post 10 of the resistor block 5 at different positions, thereby adjusting the resistance coefficient of the circuit.

[0025] like Figures 1 to 3 As shown, pin 6 includes a selection pin 14 and a fixed pin 15. Both the selection pin 14 and the fixed pin 15 are fixedly installed on the bottom inner wall of the mounting bracket 4. The selection pin 14 and the fixed pin 15 are electrically connected to the wiring terminals of the first filament circuit 2 and the second filament circuit 3, respectively.

The controller 11 controls the operation of the first motor 12 or the second motor 17. When using different filament circuits, the operation of the second motor 17 drives the second connecting spring 19 to make a contact-type electrical connection with one of the selection pins 14 on the two sets of pins 6. This realizes the closed circuit between the power input line 8, the resistor block 5, the resistor wire 7, the electrode post 10, the first connecting spring 9, the connecting wire 20, the second connecting spring 19, the selection pin 14, the first filament circuit 2 or the second filament circuit 3, the fixed pin 15, and the power output line 16. This allows control of the illumination of the first filament circuit 2 or the second filament circuit 3, and the selection of different light levels.

[0029] The first motor 12 drives the first connecting spring 9 to rotate, controlling the connection between the first connecting spring 9 and the top electrode post 10 of the resistor block 5 at different positions. This adjusts the resistance coefficient in the connected circuit, thereby adjusting the light intensity of the first filament circuit 2 or the second filament circuit 3.
