Description

Technical Field

[0001] This invention relates to the field of lighting, and more particularly to switch switching. Background Technology

[0002] Currently, many lighting products use toggle switches to switch between different color temperatures, and many also use wall switches to achieve various dimming and color adjustment functions. However, there is no means to combine these two functions to meet people's different needs. Summary of the Invention

[0003] The main technical problem to be solved by the present invention is to provide a control circuit that can satisfy both the needs of some customers who want simple single-color temperature selection and the needs of other customers who want diverse dimming and color adjustment functions.

[0004] To solve the above-mentioned technical problems, the present invention provides a control circuit for switching color temperature and wall-controlled dimming and color adjustment using an MCU and a toggle switch, including: a dimming and color adjustment circuit, an MCU detection and control circuit, an LED light source and a toggle switch control circuit;

[0005] The MCU detection and control circuit outputs a first control signal and a second control signal to the dimming and color-tuning circuit to adjust the brightness of the LED light source and switch the color temperature of the LED light source.

[0006] The toggle switch control circuit is used to output different I / O1 voltages to the MCU detection and control circuit, so that the MCU detection and control circuit outputs first control signals and second control signals with different duty cycles, or so that the MCU detection and control circuit detects the state of the wall switch and outputs first control signals and second control signals with corresponding duty cycles to realize the dimming and color adjustment of the wall switch.

[0007] In a preferred embodiment: the toggle switch control circuit has four positions. When the toggle switch is to position 1, position 2, and position 3, the MCU detection and control circuit outputs a first control signal and a second control signal with different duty cycles.

[0008] When the toggle switch is turned to position 4, the MCU detection and control circuit detects the status of the wall switch and outputs the first and second control signals with corresponding duty cycles to realize the dimming and color adjustment of the wall switch.

[0009] In a preferred embodiment: the toggle switch control circuit includes a toggle switch S1, resistors R1, R2, R3, R4, and R5; pin 3 of the toggle switch is connected to R1 and connected to VCC; resistors R2, R3, R4, and R5 are respectively connected between pin 1, pin 2, pin 4, pin 5, and GND ground.

[0010] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0011] This invention provides a control circuit that utilizes an MCU and a toggle switch to switch color temperature and wall-controlled dimming and color adjustment. Different color temperatures can be switched between different toggle switch positions, and when toggled to one position, it can be converted into a wall-controlled dimming and color adjustment function. This satisfies both customers who want simple single-color temperature selection and those who require diverse dimming and color adjustment functions. Attached Figure Description

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0014] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0016] refer to Figure 1 This embodiment provides a control circuit for switching color temperature and wall-controlled dimming and color adjustment using an MCU and a toggle switch, including: a dimming and color adjustment circuit, an MCU detection and control circuit, an LED light source and a toggle switch control circuit;

[0017] The MCU detection and control circuit outputs a first control signal and a second control signal to the dimming and color-tuning circuit to adjust the brightness of the LED light source and switch the color temperature of the LED light source.

[0018] The toggle switch control circuit is used to output different I / O1 voltages to the MCU detection and control circuit, so that the MCU detection and control circuit outputs first control signals and second control signals with different duty cycles, or so that the MCU detection and control circuit detects the state of the wall switch and outputs first control signals and second control signals with corresponding duty cycles to realize the dimming and color adjustment of the wall switch.

[0019] Specifically, the toggle switch control circuit described in this embodiment has four positions. When the toggle switch is to position 1, position 2, or position 3, the MCU detection and control circuit outputs a first control signal and a second control signal with different duty cycles.

[0020] When the toggle switch is turned to position 4, the MCU detection and control circuit detects the status of the wall switch and outputs the first and second control signals with corresponding duty cycles to realize the dimming and color adjustment of the wall switch.

[0021] To achieve the above effect, the toggle switch control circuit includes a toggle switch S1, resistors R1, R2, R3, R4, and R5; pin 3 of the toggle switch is connected to R1 and connected to VCC; resistors R2, R3, R4, and R5 are respectively connected between pin 1, pin 2, pin 4, pin 5, and GND ground.

[0022] When the toggle switch is turned to position 1, 2, and 3 in sequence, the voltage values ​​corresponding to the output I / O1 voltage are V1, V2, and V3 respectively due to the different resistance values. At this time, the MCU outputs different PWM1 and PWM2 to achieve three different color temperatures and brightness levels.

[0023] When the toggle switch is moved to the 4 positions in sequence, the corresponding voltage value is V4. At this time, the MCU detection circuit detects the status of the wall switch and outputs specific PWM1 and PWM2 to realize the dimming and color adjustment of the wall switch.

[0024] The above process, through the switching of the toggle switch, not only achieves the conventional switching between multiple color temperatures, but also enables the complete wall switch control function by toggling one of the toggle switches.

[0025] The above description is merely a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention by those skilled in the art within the scope of the technology disclosed in the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
