[0023] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0025] refer to Figure 1 , Figure 2 and Figure 3 . Figure 1 It is a structural schematic diagram of an intelligent LED lamp control device for adjusting the minimum brightness. Figure 2 It is a system diagram of connecting an intelligent LED lamp control device for adjusting minimum brightness with an external intelligent LED lamp. Figure 3 It is a structural schematic diagram of the connection between an intelligent LED lamp control device for adjusting the minimum brightness and an external intelligent LED lamp.

[0026] The intelligent LED lamp control device for adjusting the minimum brightness mainly provides control information to the intelligent LED lamp, so that the intelligent LED lamp can be set to the minimum brightness, which is convenient for people to set the minimum brightness of the intelligent LED lamp at any time, thereby improving the convenience of people using the intelligent LED lamp.

[0027] In this specific embodiment, a smart LED lamp control device for adjusting the minimum brightness is provided, including: a substrate 100, a microcontroller chip 300, a switch group, a current limiting resistor 200, a first terminal 401, a second terminal 402 and a third terminal 403.

[0028] The substrate 100 is also called a circuit substrate. The circuit substrate is a basic material for manufacturing a PCB (printed circuit board), and is mainly composed of a copper-clad laminate. During the manufacturing process, the desired circuit pattern is obtained by selectively processing holes, chemical copper plating, electroplating copper, etching, etc. on the substrate 100 material.

[0029] The substrate 100 in the present application is used to carry the microcontroller chip 300, the switch group, the current limiting resistor 200, the first terminal 401, the second terminal 402 and the third terminal 403. In addition to the electronic components welded on the substrate 100, a circuit structure is also printed on the substrate 100, through which the microcontroller chip 300, the switch group, the current limiting resistor 200, the first terminal 401, the second terminal 402 and the third terminal 403 are connected.

[0030] The microcontroller chip 300 is an integrated circuit chip that can perform control functions or output control signals. The microcontroller chip 300 implements the function of receiving or outputting signals through its pins. The switch group refers to a collection of several switches. The current limiting resistor 200 limits the current flowing through it to protect the input interface of the microcontroller chip 300.

[0031] In the present application, the microcontroller chip 300 is provided with a first output interface 310, a second output interface 320 and n input interfaces; the switch group includes: n switches; wherein n is a positive integer, and n is greater than or equal to 2; the first output interface 310 is connected to one end of the current limiting resistor 200, and the other end of the current limiting resistor 200 is respectively connected to one end of the i-th switch, and the other end of the i-th switch is connected to the i-th input interface; wherein i=1,2,…,n.

[0032] For the sake of convenience, in this specific embodiment, n is equal to 2, that is, the switch group has 2 switches, and the microcontroller chip 300 has 2 output interfaces. The 2 output interfaces of the microcontroller chip 300 are the first output interface and the second output interface. The 2 switches of the switch group are the first switch 201 and the second switch 202.

[0033] Therefore, in this specific embodiment, the first output interface 310 is connected to one end of the current limiting resistor 200, the other end of the current limiting resistor 200 is respectively connected to one end of the first switch 201 and one end of the second switch 202, the other end of the first switch 201 is connected to the first input interface, and the other end of the second switch 202 is connected to the second input interface.

[0034] The power supply terminal of the microcontroller chip 300 is connected to the first wiring terminal 401 , the ground terminal of the microcontroller chip 300 is connected to the second wiring terminal 402 , and the second output interface 320 is connected to the third wiring terminal 403 .

[0035] During specific operation, the external power supply provides power to the microcontroller chip 300 through the first terminal 401 and the second terminal 402. The first output interface 310 of the microcontroller chip 300 outputs a high level, which acts on the first switch 201 and the second switch 202 through the current limiting resistor 200. The user can send a combined signal to the microcontroller chip 300 by turning on and off the first switch 201 and the second switch 202.

[0036] When the user operates the first switch 201, so that the first switch 201 is turned on, the high-level signal passes through the current-limiting resistor 200 and is used in the first input interface of the microcontroller chip 300. At this time, the signal received by the first input interface of the microcontroller chip 300 is "1". When the user operates the first switch 201, so that the first switch 201 is turned off, the high-level signal cannot pass through the current-limiting resistor 200 and is used in the first input interface of the microcontroller chip 300. At this time, the signal received by the first input interface of the microcontroller chip 300 is "0".

[0037] Similarly, when the user operates the second switch 202, so that the second switch 202 is turned on, the high-level signal passes through the current-limiting resistor 200 and is used in the second input interface of the microcontroller chip 300. At this time, the signal received by the second input interface of the microcontroller chip 300 is "1". When the user operates the second switch 202, so that the second switch 202 is turned off, the high-level signal cannot pass through the current-limiting resistor 200 and is used in the second input interface of the microcontroller chip 300. At this time, the signal received by the second input interface of the microcontroller chip 300 is "0".

[0038] It can be seen that the user generates four signal combinations by operating the first switch 201 and the second switch 202, namely: "10", "00", "11" and "01". The microcontroller chip 300 can load information on these four signal combinations. Thus, four minimum brightness limits can be obtained. In this specific embodiment, the four minimum brightness limits are: "00" represents the minimum adjustable brightness of 1%, "01" represents the minimum adjustable brightness of 2%, "10" represents the minimum adjustable brightness of 3%, and "11" represents the minimum adjustable brightness of 4%. Users can choose the appropriate switch combination according to actual needs to adjust the minimum adjustable brightness of the smart LED lamp.

[0039] After the microcontroller chip 300 determines the signal combination of the switch group, it can generate a corresponding control signal to be transmitted to the smart LED lamp through the second output interface 320 of the microcontroller chip 300, so that the smart LED lamp can limit its minimum adjustable brightness.

[0040] The utility model forms a signal combination through the switch operation of the switch group, so that the user can use the signal combination to let the microcontroller chip 300 form a control signal, so as to control the lowest adjustable brightness of the external intelligent LED lamp, providing convenient conditions for people to control the intelligent LED lamp.

Some common PCB substrate 100 materials are: FR-4 (glass fiber reinforced plastic): This is a commonly used PCB board substrate material with excellent insulation, heat resistance and mechanical properties, suitable for most electronic devices. FR-4 can also improve conductivity by adding a metal foil layer. CEM-3 (cellulose reinforced plastic): Compared with FR-4, CEM-3 is more economical. It has good mechanical strength and electrical properties, but its heat resistance is slightly inferior to FR-4. Metal substrate 100: This is a PCB board with metal as a substrate, which has high thermal conductivity and mechanical strength and is suitable for high-power electronic devices and high-frequency electronic devices. PTFE (polytetrafluoroethylene): PTFE is an excellent high-frequency electronic material with excellent dielectric properties and heat resistance, suitable for high-frequency electronic devices. Polyimide resin glass fiber laminate: This material can be used as a rigid or flexible circuit substrate material. Its strength and stability at high temperatures are better than FR-4 laminates, and it is often used in high-reliability military products. Polytetrafluoroethylene glass fiber laminates (GX and GT laminates): The dielectric properties of these materials can be controlled and can be used in products with strict dielectric constant requirements, while the dielectric properties of GX are better than GT and can be used in high-frequency circuits. In some preferred further specific embodiments, the substrate 100 is a glass fiber reinforced plastic material component.

[0044] In some preferred further specific embodiments, the resistance of the current limiting resistor 200 is 1 kΩ to 2 kΩ.

A dip switch is also called a DIP switch, an overclocking switch, an address switch, a pull switch, a digital switch and a finger switch. It is an address switch used for operation control. It adopts the binary coding principle of 0 / 1. There are two pins on the upper and lower back of each key. When it is turned to the ON side, the two pins will be connected, otherwise they will be disconnected.
