Detailed description of the preferred embodiments

Example 1:

the present embodiment provides a plug-in type filament, which, referring to fig. 1 to 3, includes a substrate 10, and a built-in control IC chip 20, a white light circuit 31, a red light circuit 32, a green light circuit 33, and a blue light circuit 34 disposed on the substrate 10. The built-in control IC chip 20 is provided with a ground pin GND, a power supply voltage pin VDD, a signal input pin DIN, a signal output pin DOUT, a white light control pin W, a red light control pin R, a green light control pin G, and a blue light control pin B. One end of the white light circuit 31, one end of the red light circuit 32, one end of the green light circuit 33, and one end of the blue light circuit 34 are electrically connected to the white light control pin W, the red light control pin R, the green light control pin G, and the blue light control pin B of the built-in control IC chip 20, respectively, and the other ends are electrically connected to the power supply pin.

One side of base plate is equipped with four electric connection terminal, is VDD terminal, GND terminal, DIN terminal and DOUT terminal respectively, wherein:

the VDD terminal is used for connecting a power supply VDD anode and is electrically connected with a power supply pin of the built-in control IC chip 20;

the GND terminal is used for connecting a power supply cathode and is electrically connected with a grounding pin of the built-in control IC chip;

the DIN terminal is for receiving a control signal, and is electrically connected to a signal input pin of the built-in control IC chip 20;

the DOUT terminal is used to send a control signal to the next wick, and is electrically connected to a signal output pin of the built-in control IC chip 20.

The substrate 10 is also printed with a circuit structure, and the built-in control IC chip 20, the white light circuit 31, the red light circuit 32, the green light circuit 33 and the blue light circuit 34 are arranged on the substrate 10 and electrically connected through the circuit structure on the substrate 10. The substrate 10 may be made of ceramic, sapphire, glass fiber, polyimide substrate (PI substrate), Printed Circuit Board (PCB), flexible printed circuit board (FPC), or the like.

The built-in control IC chip 20 controls the light emitting of each light emitting circuit according to the received signals, thereby realizing the control and adjustment of the color temperature and the color of the filament. A grounding pin GND is grounded, a power voltage pin VDD is electrically connected with power voltage, a signal input pin DIN is used for receiving control signals, and a signal output pin DOUT is a standby pin and is used for sending the control signals to the next filament when a plurality of filaments are connected in series. The white light control pin W, the red light control pin R, the green light control pin G and the blue light control pin B are electrically connected, and transmit corresponding control signals to the white light circuit 31, the red light circuit 32, the green light circuit 33 and the blue light circuit 34.

The RGBW signal control chip is adopted by the built-in control IC chip 20, each light-emitting circuit can be controlled respectively, the color temperature and the color of the lamp filament can be adjusted, and the lamp filament can be changed more abundantly. For example: the red light circuit 32, the green light circuit 33 and the blue light circuit 34 can be controlled to integrally emit white light mixed light with adjustable chromaticity, and the color temperature of the white light circuit 31 is controlled, so that the stable transition of the adjustment of the color temperature of the filament can be realized, and a user can adjust the proper color temperature according to the environment; the red light circuit 32, the green light circuit 33 and the blue light circuit 34 can also be controlled to enable the whole light emitting color and the color temperature of the mixed light to be adjustable, and at the moment, the color temperature of the white light circuit 31 can also be controlled simultaneously, so that the user can realize personalized light adjustment according to the environment.

As shown in fig. 1, in some possible schemes, the white light circuit 31, the red light circuit 32, the green light circuit 33, and the blue light circuit 34 each include a plurality of blue LED chips connected in series, and the blue LED chips emit white light, red light, green light, and blue light corresponding to the white light circuit, the red light circuit, the green light circuit, and the blue light circuit by exciting different phosphors.

In practical application, white light, red light and green light can be obtained after different fluorescent powders are excited by blue light emitted by a blue light LED chip, and the white light can be obtained only by coating yellow fluorescent powder outside the blue light LED chip by taking the white light as an example.

In practical applications, only the white light circuit may be selected to use a plurality of blue LED chips connected in series to excite the phosphor powder to emit white light, or the white light circuit 31 may directly use a plurality of white LEDs connected in series. At this time, the red light circuit 32 may adopt a plurality of red LED chips connected in series; the green circuit 33 may employ a plurality of green LED chips connected in series; the blue circuit 34 may employ a plurality of blue LED chips connected in series. Or the white light circuit, the red light circuit, the green light circuit and the blue light circuit are connected in series and in parallel by the free-light-emitting LED CHIP in a CSP packaging or CHIP packaging manner to realize the emission of white light, red light, green light and blue light.

In some possible solutions, referring to fig. 1, the number of red LED chips of the red circuit 32 is 1.5 times that of the green LED chips of the green circuit 33, and the number of green LED chips and blue LED chips is equal.

In practical application, the standard operating voltage of the red LED chip is 2v, the standard operating voltage of the green LED chip and the blue LED chip is 3.3v, and under the condition of the same voltage, the red circuit 31 can have more red LED chips connected in series, but the inventor finds that in the existing LED technology, if the red LED chip, the green LED chip and the blue LED chip are used at the same time in the same LED lighting product, the number of the three chips is the same, which causes waste of electric quantity, therefore, in order to save electric quantity, the number of the red LED chips of the red circuit 32 is set to be 1.5 times of the number of the green LED chips of the green circuit 33 according to the voltage ratio of the red LED chip and the green LED chip (or the blue LED chip).

In some feasible schemes, the blue LED chip, the green LED chip, the red LED chip or the white LED chip may adopt a front-mounted chip, a flip chip, a CSP packaged chip or a COB bare chip.

In some possible implementations, referring to fig. 1 and 3, the filament surface is coated with a first encapsulating phosphor 41 corresponding to the white light circuit 31 and a second encapsulating phosphor 42 corresponding to the red light circuit 31, the green light circuit 32, and the blue light circuit 33.

The fluorescent powder is coated on the filament, so that the light emitted by each LED chip can be fused together, and the light emitted by the filament is more uniform. Because the light emission of the red light circuit 31, the green light circuit 32 and the blue light circuit 33 forms color mixed light with adjustable color, the second packaging fluorescent powder 42 is required to be coated on the red light circuit 31, the green light circuit 32 and the blue light circuit 33, so that the color mixed light generated by the three light emitting circuits is more uniform.

The first encapsulating phosphor and the second encapsulating phosphor may be the same or different.

In practical application, the first encapsulating phosphor 41 and the second encapsulating phosphor 42 can be replaced by the first encapsulating white latex and the second encapsulating white latex.

In practical application, in order to reduce the processing cost, the control IC chip is embedded in any side of the filament, and the connection channel can be simplified to 4 channels (as shown in fig. 1, including VDD positive electrode, GND negative electrode, DIN signal input and DOUT signal output), so that the adjustment and conversion control of multi-color signals can be realized while the process is simplified.

In practical applications, the filament may be in the shape of a strip, a spiral, or other shapes.
