LED Color Temperature Adjustment Device and Lamp

A lamp, at least comprising an adjustment device and a first LED, the first LED being communicably connected to the adjustment device, wherein

• the adjustment device comprises a first control module, a second control module, a first LED driver module and a first regulating switch, wherein the first regulating switch comprises a plurality of positions, and each position corresponds to a different color temperature;
• the first regulating switch has an output end connected to an input end of the first control module, and is configured to receive a position closed operation by a user and output to the first control module a position signal of a target position corresponding to the position closed operation;
• the first control module has an output end electrically connected to an input end of the second control module and an input end of the first LED driver module respectively, and is configured to receive the position signal, output a first control signal to the first LED driver module, and output a color temperature adjustment signal to the second control module;
• the first LED driver module has an output end electrically connected to the first LED, and is configured to receive the first control signal and output a first driving signal to the first LED;
• the second control module has an output end electrically connected to the first LED, and is configured to receive the color temperature adjustment signal and output a target color temperature signal to the first LED;
• and
• the first LED is configured to receive the first driving signal and the target color temperature signal, whereby the first LED lights up and emits a target color temperature of light corresponding to the target position.
