Description

Technical Field

[0001] The utility model relates to the technical field of dimming and color adjustment, in particular to a wireless dimming and color adjustment control circuit and an electronic switch. Background Art

[0002] At present, the main types of dimming controllers are as follows:

[0003] (1) Thyristor dimmer: Its principle is to adjust the conduction angle of each half-wave of the alternating current to change the sinusoidal waveform, thereby changing the effective value of the alternating current to achieve the purpose of dimming.

[0004] Disadvantage 1: Because the dimmer is connected in series in the circuit, the rated power of the load must be considered, and it can only adjust the input power, and cannot achieve other functions such as color switching.

[0005] Disadvantage 2: Even when adjusted to the lowest gear, a weak current still flows. When used on low-power lamps, there may still be a weak glow after the LED is turned off.

[0006] (2) 0-10V dimming: Change the brightness of the lamp by simulating the (0-10V) voltage amplitude;

[0007] Disadvantages: It requires the addition of extra signal lines and the consistency is poor when controlling multiple lights.

[0008] (3) DALI dimming: Accurately dim and adjust the light intensity of a single lamp or a group of lamps through the DALI system protocol.

[0009] Disadvantages: It requires the addition of extra signal lines, high system maintenance costs, and the cost of DALI lamps and drivers. Utility Model Content

[0050] From the above description, it can be seen that by setting up a mounting base and arranging an iron sheet that matches the magnetic block on the mounting base, when the user uses it, he only needs to fix the mounting base with the iron sheet, and the switch body with the magnetic block can be directly fixed on the mounting base by magnetic attraction. The user can install and remove the product through simple magnetic attraction operation, which is very convenient and quick.

[0060] The Bluetooth MESH module 1 is powered by two AAA batteries;

[0061] The button S1 is connected to the Bluetooth MESH module 1 and is used for the coding, decoding and all group selection functions of the controlled lamp 4.

[0071] The working principle of the above wireless dimming and color adjustment control circuit is as follows:

[0072] BAT1 is two AAA batteries, which power each module through capacitors C1 and C2; resistors R1, R2 and R3 are all pull-up resistors, which can output waveforms for each pin of the rotary encoder SW1 and provide high-level driving capability; resistors R4, R5 and R6 are all current-limiting resistors, which can prevent excessive current from damaging the chip U1 or the rotary encoder SW1; the forward, reverse and pressing of the rotary encoder SW1 all have different waveforms, and the chip U1 sends the corresponding waveform function data after recognizing the corresponding waveform, thereby realizing the dimming and color adjustment of the controlled lamp 4.

[0073] Resistor R13 is a pull-down resistor, which provides an initial low level for button S1. When button S1 is pressed, button S1 is in the on state, and the initial low level of button S1 becomes the high level of BAT1. After chip U1 recognizes that the level changes to a high level, it recognizes that button S1 has been pressed; Resistor R14 is a pull-down resistor, which provides an initial low level for button S2. When button S2 is pressed, button S2 is in the on state, and the initial low level of button S2 becomes the high level of BAT1. After chip U1 recognizes that the level changes to a high level, it recognizes that button S2 has been pressed; Resistor R15 is a pull-down resistor, which provides an initial low level for button S3. When button S3 is pressed, button S3 is in the on state, and the button is pressed. The initial low level of key S3 changes to the high level of BAT1. After the chip U1 recognizes that the level changes to the high level, it recognizes that key S3 is pressed; the resistor R16 is a pull-down resistor, which provides an initial low level for key S4. When key S4 is pressed, key S4 is in the on state, and the initial low level of key S4 changes to the high level of BAT1. After the chip U1 recognizes that the level changes to the high level, it recognizes that key S4 has been pressed; the resistor R17 is a pull-down resistor, which provides an initial low level for key S5. When key S5 is pressed, key S5 is in the on state, and the initial low level of key S5 changes to the high level of BAT1. After the chip U1 recognizes that the level changes to the high level, it recognizes that key S5 has been pressed;

[0074] The light-emitting diode LED1 is the indicator light of the button S1, and the resistor R18 is a pull-down resistor, which can provide an initial low level to prevent the light from turning on when the power is turned on; when the chip U1 recognizes that the button S1 is pressed, it outputs a high level, and the light-emitting diode LED1 starts to light up. When the button S1 is not recognized to be pressed, it outputs a low level, and the light-emitting diode LED1 turns off; the light-emitting diode LED2 is the indicator light of the button S2, and the resistor R14 is a pull-down resistor that can provide an initial low level to prevent the light from turning on when the power is turned on. After the button S2 is pressed, one end of the button S2 becomes a high level, and the light-emitting diode LED2 lights up, otherwise it will not light up; the light-emitting diode LED3 is the indicator light of the button S3, and the resistor R 15 can provide an initial low starting level to prevent the light from turning on when the power is turned on. After the button S3 is pressed, one end of the button S3 becomes a high level, and the light-emitting diode LED3 lights up, otherwise it will not light up; the light-emitting diode LED4 is the indicator light of the button S4, and the resistor R16 can provide an initial low starting level to prevent the light from turning on when the power is turned on. After the button S4 is pressed, one end of the button S4 becomes a high level, and the light-emitting diode LED4 lights up, otherwise it will not light up; the light-emitting diode LED5 is the indicator light of the button S5, and the resistor R17 can provide an initial low starting level to prevent the light from turning on when the power is turned on. After the button S5 is pressed, one end of the button S5 becomes a high level, and the light-emitting diode LED5 lights up, otherwise it will not light up.

[0075] Resistor R8 is a current limiting resistor, which can prevent excessive current from damaging the light-emitting diode LED1; resistor R9 is a current limiting resistor, which can prevent excessive current from damaging the light-emitting diode LED2; resistor R10 is a current limiting resistor, which can prevent excessive current from damaging the light-emitting diode LED3; resistor R11 is a current limiting resistor, which can prevent excessive current from damaging the light-emitting diode LED4; resistor R12 is a current limiting resistor, which can prevent excessive current from damaging the light-emitting diode LED5.

[0077] (1) The above-mentioned complex logic dimming function can be completed with fewer components, reducing device costs.

[0078] (2) The dimmer does not require mains power supply, which makes it easy to install the dimmer in more environments and also easy to move.

[0079] (3) Different from traditional thyristor, 0-10V, 1-10V and DALI wired control dimmers, wireless dimming can be performed without adding external signal lines; the dimming depth depends on the LED driver chip in the controlled lamp 4, and theoretically can support 0%-100% brightness dimming.

[0080] (4) The controlled lamps 4 can be coded, decoded and grouped, and the lamps to be controlled can be flexibly controlled.

[0081] (5) The controlled lamp 4 is based on the BLE-MESH protocol relay function, which can expand the coverage and reliability of the network and complete wireless control at a distance greater than 30M.
