If the initial condition of light tube group 120 is a turn-off in step 400; First state of switch 110 corresponds to the closed condition of light tube group 120 at this moment; Second state of switch 110 corresponds to the opening of light tube group 120; First brightness corresponds to light tube group 120 complete dark when initial condition, and second brightness corresponds to the high-high brightness of light tube group 120.When the user turns on light through the state of diverter switch 110, the present invention understand execution in step 420 with light tube group 120 in the light modulation time T
DIMIn increase gradually to second brightness (for example rising to bright entirely) by first brightness by full shadow.If the user is in the light modulation time T
DIMIn the state of diverter switch 110 once more not, the present invention understands execution in step 470, is surpassing the light modulation time T
DIMAfter light tube group 120 is maintained second brightness (for example bright entirely).In the light modulation time T
DIMIn, the user can close light tube group 120 through the state of diverter switch 110 again, or through once again twice apace the state of diverter switch 110 select the brightness of light tube group 120: when the user only in the light modulation time T
DIMThe second interior time point T2 is the state of diverter switch 110 again, and the present invention's this moment is execution in step 430,440 and 400 in regular turn, therefore can when the second time point T2, close light tube group 120; When the user in the light modulation time T
DIMSecond interior time point T2 and the 3rd time point T3 be the state of twice diverter switch 110 once again; First kind of situation possibly be to want the second time point T2 to close light tube group 120; And open light tube group 120 once more at the 3rd time point T3; Second kind of situation then possibly be to want at second time point T2 adjustment lighting tube brightness, so the present invention is with turn-off time T
OFFJudge whether twice " apace " diverter switch of user.When the user in the light modulation time T
DIMSecond interior time point T2 and the 3rd time point T3 be the state of twice diverter switch 110 once again, and the interval of the second time point T2 and the 3rd time point T3 is not more than turn-off time T
OFFThe present invention's this moment can judge that the user is the brightness of adjusting light tube group in the second time point T2 desire through " twice diverter switch " apace; Therefore execution in step 430,440,450 and 460 in regular turn, and then the brightness when light tube group 120 maintained time point T2 (for example between complete bright and complete any brightness between dark); When the user in the light modulation time T
DIMSecond interior time point T2 and the 3rd time point T3 be the state of twice diverter switch 110 once again, but the interval of the second time point T2 and the 3rd time point T3 is greater than turn-off time T
OFF, the present invention's this moment can judge that the user desires to close light tube group 120 at the second time point T2, and desires to open once more light tube group 120 at the 3rd time point T3, therefore meeting execution in step 420 is to increase light tube group 120 to second brightness (for example increasing to bright entirely).In other words, after opening light tube group 120, the present invention is in the light modulation time T
DIMIncrease the brightness of light tube group 120 gradually, let the user simultaneously in the light modulation time T
DIMIn can select suitable brightness through the state of twice diverter switch 110 apace, therefore illuminator 300 of the present invention can use traditional suitching type switch that dimming function is provided, and need not use special rotary switch.
In like manner; If the initial condition of light tube group 120 is the state of turning on light in step 400; First state of switch 110 corresponds to the opening of light tube group 120 at this moment; Second state of switch 110 corresponds to the closed condition of light tube group 120, and first brightness corresponds to the high-high brightness of light tube group 120, and second brightness corresponds to light tube group 120 complete dark when initial condition.When the user turns off the light through the state of diverter switch 110, the present invention understand execution in step 420 with light tube group 120 in the light modulation time T
DIMIn downgrade second brightness (for example reducing to complete dark) gradually by first brightness by full high light.If the user is in the light modulation time T
DIMIn the state of diverter switch 110 once more not, the present invention understands execution in step 470, is surpassing the light modulation time T
DIMAfter light tube group 120 is maintained second brightness (for example complete dark).In the light modulation time T
DIMIn, the user can open light tube group 120 through the state of diverter switch 110 again, or through once again twice apace the state of diverter switch 110 select the brightness of light tube group 120: when the user only in the light modulation time T
DIMThe second interior time point T2 is the state of diverter switch 110 again, and the present invention's this moment is execution in step 430,440 and 400 in regular turn, therefore can when the second time point T2, open light tube group 120; When the user in the light modulation time T
DIMSecond interior time point T2 and the 3rd time point T3 be the state of twice diverter switch 110 once again, and the interval of the second time point T2 and the 3rd time point T3 is not more than turn-off time T
OFF, the present invention's this moment execution in step 430,440,450 and 460 in regular turn, the brightness so that light tube group 120 is maintained time point T2 (for example between complete bright and complete any brightness between dark).In other words, after closing light tube group 120, the present invention is in the light modulation time T
DIMDowngrade the brightness of light tube group 120 gradually, let the user simultaneously in the light modulation time T
DIMIn can select suitable brightness through the state of twice diverter switch 110 apace, therefore illuminator 300 of the present invention can use traditional suitching type switch that dimming function is provided, and need not use special rotary switch.
