[0045] Through the circuit design described above, the first resistor R1 can be used as an auxiliary current path for other power levels, thereby reducing the number of resistors used in the power adjustment module 14.

[0046] Through the circuit design described above, the lighting adjustment circuit 1 can simultaneously provide color temperature adjustment and power adjustment functions, allowing users to conveniently adjust both the color temperature and power of the lighting device at the same time.

[0054] It is worth mentioning that existing lighting fixtures typically require external controllers or complex circuit designs to adjust different power and color temperatures. For example, the power adjustment switch and color temperature adjustment switch of existing lamps are located on their two end caps, so users need to use these switches separately to adjust power and color temperature, which is extremely inconvenient.

The above circuit design can effectively reduce the number of resistors in the power adjustment module, thereby significantly simplifying the lighting adjustment circuit. Therefore, the cost of the lighting adjustment circuit can be significantly reduced to meet the needs of different applications.

[0058] Furthermore, according to embodiments of this application, the circuit design of the lighting adjustment circuit allows the number of color temperature and power levels to be increased or decreased according to actual needs. Thus, the lighting adjustment circuit can not only meet the needs of different lighting devices but also the needs of a wider range of applications. Therefore, the lighting adjustment circuit is more flexible in its use and can be applied more extensively.

[0059] Furthermore, according to embodiments of this application, the lighting adjustment circuit can employ either an isolated driver or a non-isolated driver, further enhancing the reliability of the lighting adjustment circuit. Therefore, the lighting adjustment circuit can meet the needs of applications requiring high reliability.
