The lighting tube 11 is precisely controlled through the main board 4, so that the brightness and color temperature at the position where the user is currently located (i.e., the position where the remote controller is located) reach the target requirements. The lighting fixture of this embodiment that can automatically adjust the brightness according to the ambient light intensity provides a lighting mode with diverse brightness and color temperatures compared to the single lighting mode of traditional lighting equipment, and can be automatically adjusted according to the lighting requirements of a specific position, so as to accurately match the personalized lighting needs of the user at a specific position and perfectly meet the user's usage requirements.

[0056] As Figure 12 shown, the remote control main board in the remote controller starts the light sensing module according to the triggered control instruction (such as the lighting brightness control instruction or the lighting color temperature control instruction) and transmits an electrical signal of the target brightness value / target color temperature value to the light sensing module; after the light sensing module converts the detected ambient light intensity / ambient color temperature into an electrical signal, it calculates the difference from the target brightness value / target color temperature value, and transmits the difference signal to the main board through the remote control main board; the main board receives the electrical signal through the receiving module and transmits it to the control module.

[0060] The process of the adjustment main board 2 receiving the brightness difference signal / color temperature difference signal and controlling and adjusting the lighting tube 11 is that the receiving module 23 receives and transmits the brightness difference signal / color temperature difference signal to the control module 24. The control module 24 calculates the current difference to be adjusted according to the received brightness difference signal / color temperature difference signal, and adjusts the brightness / color temperature of the lighting tube 11 through the output module 25 according to the current difference.
