Technical Field

[0001] The present disclosure relates to the field of filament-type LED bulbs, and more particularly to a device used inside a filament-type LED bulb. Background Art

[0002] Filament-type LED bulbs are a kind of efficient and energy-saving lighting products, but traditional filament-type LED bulbs have many problems.

[0003] Specifically, in actual use, due to the complex design of filament-type LED bulbs, they are prone to malfunctions, which shortens the life of the bulbs and requires frequent replacement, increasing maintenance and replacement costs; since filament-type LED bulbs require workers to perform welding, and welding technology is demanding and difficult for workers to master, it is easy to cause loose welding problems, affecting the use effect of the bulbs; due to the complex structure of the bulbs, the appearance may not be beautiful enough, affecting the beauty of the bulbs in interior decoration; due to the complex structure of the bulbs, they need to be assembled from multiple parts, and the production cost is high, resulting in a high product price, affecting the market competitiveness of the product; due to loose welding or poor quality of parts, it is easy to cause poor contact of the bulb, affecting the luminous effect and stability of the bulb.

[0004] In order to solve these problems, the present application aims to reduce the number of wire connections between the LED inside the LED bulb and the external signal source or power source by adopting new design and manufacturing technology. Utility Model Content

[0005] In view of this, the present disclosure proposes an improved lighting device, in which, by reducing the number of wire connections between the LED inside the lighting device and the external signal source or power source, not only the poor contact caused by welding is reduced to improve product quality, but also the aesthetics of the lighting device is improved and the size of the lighting device is reduced.

[0006] According to one aspect of the present disclosure, a lighting component is provided, having multiple LEDs, and the lighting component includes: a receiver connected to an external source through a first number of wires to receive a first power signal and a control signal from the external source, the control signal indicating a driving parameter of each LED in the multiple LEDs; a first driver connected to the receiver to receive the first power signal and the control signal, outputting a driving signal to control each LED, and connected to the multiple LEDs through a second number of wires to output a driving signal to the multiple LEDs to drive the multiple LEDs; wherein the first number is less than the second number.

[0007] In this way, the present disclosure reduces the number of wires connected between the LED inside the bulb and the external source by providing a lighting assembly inside the lighting device, a wire connection between the device and the external source, and a wire connection between the device and a plurality of LEDs. Since the number of wire connections with the external source is reduced, poor contact due to welding is reduced, product quality is improved, the size of the lighting device is reduced, and the aesthetics of the lighting device is also improved.

[0008] According to an exemplary embodiment of the present disclosure, the first number is 2, wherein a first conductor of the two conductors simultaneously transmits a first power signal and a control signal, and a second conductor is a neutral line.

[0009] In this way, the first wire and the second wire provide a loop to ensure the balance of current and provide stability and reliability of the system. Without affecting the transmission of power signals and control signals, the internal LED is connected to the external source through 2 wires.

In addition, by connecting multiple LEDs in parallel, a larger lighting area and brighter lighting effect can be achieved. At the same time, this connection method can also reduce the load on the power supply and extend the service life of the LED lamp.

[0014] According to an exemplary embodiment of the present disclosure, the plurality of LEDs include at least a red LED emitting red light, a green LED emitting green light, a blue LED emitting blue light, and a yellow LED emitting yellow light.

[0015] In this way, the present disclosure realizes a color-changing light bulb through a combination of multi-color LEDs, and the colors of the LEDs in the present disclosure are not limited to the colors disclosed above, for example, the LEDs can also emit white light, etc.

This connection method can realize the control of LED lights of different colors, and control the brightness and color of the LED by adjusting the current of each branch to achieve colorful lighting effects. At the same time, the series connection can ensure that the LED lights are evenly distributed in the circuit, avoiding the situation where the entire lamp fails due to damage to a single LED lamp. Overall, this connection method can effectively control the light effect and color of the LED, and improve the stability and reliability of the lamp. However, the connection method of the LED disclosed in the present invention is not limited to the above disclosure.

[0018] According to an exemplary embodiment of the present disclosure, the external source includes: a second driver, connected to a power supply to receive a second power signal and convert the second power signal into the first power signal according to the control signal; a transmitter, connected to the second driver to receive the first power signal; and a controller, connected to the second driver and the transmitter to send a control signal to the second driver and the transmitter; wherein, after receiving the control signal, the transmitter transmits the first power signal and the control signal to the receiver of the device.

[0020] In this way, through the cooperation of these components, the lighting assembly can receive the required power signal from the external source to meet the operating requirements of the lighting device.

[0021] According to an exemplary embodiment of the present disclosure, the receiver simultaneously receives the first power signal and the control signal from the transmitter via one wire using a power line carrier PLC technology.

[0022] According to an exemplary embodiment of the present disclosure, the receiver receives the first power signal and the control signal respectively from the transmitter via different wires using a single-wire zero-code technology or a single-bus protocol.

By using the power line carrier PLC technology, the receiver can simultaneously receive the first power signal and the control signal, thereby realizing data transmission and remote control. In addition, through the single-line return-to-zero code technology or the single bus protocol, the receiver can receive the first power signal and the control signal separately, realizing more flexible data transmission and control operations. The application of these technologies can improve the performance and efficiency of the lighting device and make communication more convenient and reliable.

[0024] According to another aspect of the present disclosure, a lighting device is provided, comprising a power connector; a lampshade fixedly connected to the power connector; a plurality of LEDs disposed in the lampshade; and a lighting assembly, wherein an external source is disposed in the power connector.

[0045] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement embodiments of the present application. However, the present application can be implemented in many different forms and should not be construed as being limited to the embodiments described herein. In the accompanying drawings, for the sake of clarity, parts that are irrelevant to the description of the present application will be omitted. Similar reference numerals refer to similar elements throughout the description. In addition, when providing a description with reference to the accompanying drawings, although the elements are represented by the same numerals, the reference numerals relating to the elements may be changed, and the reference numerals are described only for the convenience of description, and should not be understood as the concept, feature, function or effect of the element being limited by the reference numeral.

[0046] In the prior art, a color-changing filament lamp usually includes five wire connections. This large number of wire connections makes it difficult for workers to weld, and easily produces a bulb with poor contact, poor product quality, and unsightly appearance. In view of the problems in the prior art, the present application aims to simplify wiring by reducing the number of wires passing through the bulb to connect the internal LED with the external signal and power source, thereby reducing the difficulty of welding, improving product quality, and improving the appearance.

[0047] Figure 1 Schematic diagram of the appearance of the lighting device according to the first embodiment of the present disclosure.

[0048] like Figure 1 As shown, the lighting device 1 includes a power connector 11, a lampshade 12 fixedly connected to the power connector 11, a plurality of LEDs 13 arranged in the lampshade 12, a lighting component 10, an external source 14 and wires connecting various components.

[0049] The connection modes of the power connector 11 and the lampshade 12 mainly include threaded connection, snap connection, spring connection and magnetic connection, but the present disclosure is not limited to these connection modes.

[0050] The materials forming the lampshade 12 generally include: glass, metal, plastic, acrylic, wood, etc. The shape of the lampshade 12 can be any shape.

[0051] One lighting assembly 10 or a plurality of lighting assemblies 10 may be disposed in the lampshade 12 .

[0052] The external source 14 provides a first power signal and a control signal, wherein the control signal indicates a driving parameter of each LED in the plurality of LEDs 13, such as a driving parameter indicating turning on or off. The external source 14 can be disposed at any position outside the lamp housing 12, for example, the external source 14 is disposed in the power connector 11.

[0053] Figure 2 It is a structural block diagram of the lighting device of the first embodiment of the present disclosure.

[0054] like Figure 2 As shown, each lighting assembly 10 includes a receiver 101 and a first driver 102. Specifically, the receiver 101 is connected to the external source 14 through a first number of wires to receive a first power signal and a control signal from the external source 14, wherein the control signal indicates a driving parameter of each LED in the plurality of LEDs 13. The first driver 102 is connected to the receiver 101 to receive the first power signal and the control signal, outputs a driving signal for controlling each LED, such as turning on or off, and is connected to the plurality of LEDs 13 through a second number of wires to output a driving signal to the plurality of LEDs 13 to drive the plurality of LEDs 13. The first number is smaller than the second number.

[0055] In the first embodiment, the first number is 2. In other words, the receiver 101 is connected to the external source 14 via two wires. The first wire of the two wires transmits the first power signal and the control signal at the same time, and the second wire is a neutral wire. The first wire and the second wire together provide a complete loop, completing the power transmission and control signal transmission between the external source 14 and the plurality of LEDs 13 in the lampshade 12.

[0056] Since only two wires are led out from the inside of the lampshade 12, the complexity of wire welding is reduced, the size of the lighting device is reduced, and the aesthetics is improved.

[0057] In the second embodiment, the first number is 3. Figure 3 As shown, the receiver 101 is connected to the external source 14 via three wires, wherein the first wire of the three wires transmits a first power signal, the second wire transmits a control signal, and the third wire is a neutral wire.

[0058] Compared with the first embodiment, the second embodiment can independently control the transmission of power and the transmission of control signals.

[0059] In the first embodiment or the second embodiment, multiple LEDs are connected to form multiple parallel branches, wherein one of the second number of wires is connected to the positive poles of the LEDs in the multiple parallel branches, and the remaining wires are respectively connected to the negative poles of the LEDs in the multiple parallel branches.

[0060] The present disclosure is not limited to the parallel connection of the plurality of LEDs, and the plurality of LEDs may be connected in parallel, in series, or in series and in parallel.

[0061] The plurality of LEDs 13 include at least a red LED that emits red light, a green LED that emits green light, a blue LED that emits blue light, and a yellow LED that emits yellow light.

[0062] The lighting device 1 of the present disclosure may be a color-changing bulb, and the LEDs of different colors may be controlled to emit light based on a control signal, thereby achieving color change of the lighting device 1. The light emission colors of the LEDs are not limited to the above colors, and other lights such as white light may also be emitted.

[0063] A plurality of red LEDs are connected in series to form a first branch, a plurality of green LEDs are connected in series to form a second branch, a plurality of blue LEDs are connected in series to form a third branch, and a plurality of yellow LEDs are connected in series to form a fourth branch, wherein the first branch, the second branch, the third branch and the fourth branch are respectively connected to the remaining wires, thereby being connected in parallel to the first driver 102.

[0064] The present invention connects red, green, blue and yellow LEDs in series into four branches, and then connects the four branches in parallel to the driver. This connection method can realize the control of LEDs of different colors, and control the brightness and color of the LED by adjusting the current of each branch through the control signal to achieve colorful lighting effects. At the same time, the series connection can ensure that the LEDs are evenly distributed in the circuit, avoiding the situation where the entire lamp fails due to damage to a single LED. Overall, this connection method can effectively control the light effect and color of the LED, and improve the stability and reliability of the lamp.

[0065] In this case, the second number is 5, and the number of the remaining wires is 4. However, the number of parallel branches of the present disclosure is not limited to 4, and those skilled in the art may set more or less number of parallel branches as needed.

[0066] Figure 2 is a structural block diagram of a lighting device according to a first embodiment of the present disclosure; Figure 4 is a structural block diagram of a lighting device according to a second embodiment of the present disclosure; Figure 5 It is a structural block diagram of a lighting device according to the third embodiment of the present disclosure.

[0067] like Figure 2 As shown, the receiver 101 of the lighting assembly 10 is connected to the external source 14 via two wires.

[0068] like Figure 4 As shown, the receiver 101 of the lighting assembly 10 is connected to the external source 14 via three wires.

[0069] like Figure 5 As shown, the receiver 101 of the lighting assembly 10 is connected to the external source 14 via two wires, and the first driver 102 is connected to the external source 14 via one wire.

[0070] The external source 14 includes a second driver 141, connected to a power source to receive a second power signal and convert the second power signal into a first power signal according to a control signal; a transmitter 142, connected to the second driver 141 to receive the first power signal; and a controller 143, connected to the second driver 141 and the transmitter 142 to send a control signal to the second driver 141 and the transmitter 142; wherein, after receiving the control signal, the transmitter 142 transmits the first power signal and the control signal to the receiver 101 of the internal device 10.

[0071] Specifically, the power source is, for example, a 220V power source. The second driver 141 receives a second power signal with a voltage of 220V from the power source, converts the 220V second power signal into a first power signal suitable for transmission and transmission, or a first power signal suitable for driving an LED according to a control signal received from the controller 143, and transmits the converted first power signal to the transmitter 142. The transmitter 142 transmits the received converted first power signal together with the control signal to the receiver 101 of the lighting assembly 10 according to the control signal received from the controller 143.

[0072] In the first embodiment, the receiver 101 and the transmitter 142 communicate using the power line carrier PLC technology, so that the receiver 101 simultaneously receives the converted first power signal and the control signal using one wire.

[0073] Power Line Carrier (PLC) technology is a communication technology that uses power lines to transmit data signals. By superimposing data signals on power lines, data, voice, video and other information can be transmitted on power lines. PLC technology is a convenient and fast communication method that does not require the laying of separate network lines, saving costs and space. PLC technology can realize functions such as remote monitoring, remote control, and data transmission, providing convenience for various application scenarios.

[0074] In the second embodiment, a single-wire return-to-zero code technology or a single bus protocol is used between the receiver 101 and the transmitter 142, so that the receiver 101 uses two wires to receive the converted first power signal and the control signal respectively.

[0075] In the third embodiment, a single-wire return-to-zero code technology or a single bus protocol is used between the receiver 101, the transmitter 142 and the controller 143, so that the receiver 101 receives the converted first power signal with two wires; the first driver 102 receives the control signal from the controller 143 with one wire.

[0076] Single-line return-to-zero technology is a digital communication technology that is often used for data transmission or encoding. In this technology, the signal line changes from high to low and then back to high again during data transmission. This ensures the accuracy and stability of data transmission because it provides clear signal edges to indicate the start and end of data.

[0077] The 1-Wire bus protocol is a protocol used for communication between electronic devices, where all devices communicate through a shared bus. In a 1-Wire bus protocol, each device has a unique address and can send and receive data through the bus. This protocol is often used to connect low-speed devices such as sensors, controllers, and peripherals. Common 1-Wire bus protocols include 1-Wire and I2C.

[0078] In the embodiments of the present disclosure, a technical solution is provided for simplifying wiring by reducing the number of wire connections between the LED inside the lighting device and the external signal source or power source by setting a lighting component, so as to at least solve the technical problems of low product quality, low aesthetics and large size of lighting devices in the prior art, and achieves the technical effect of not only reducing poor contact caused by welding and thus improving product quality, but also improving the aesthetics of the lighting device and reducing the size of the lighting device.

[0079] In the above embodiments of the present disclosure, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0080] In the several embodiments provided in the present disclosure, it should be understood that the disclosed technical contents can be implemented in other ways.

[0081] The above is only a preferred embodiment of the present disclosure. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present disclosure. These improvements and modifications should also be regarded as the scope of protection of the present disclosure.
