FIG. 4 is a schematic view of the operation interface shown in FIG. 3 applied to a desk lamp. The operation interface 14 shown in FIG. 3 has a switch portion (4), and the switch portion (4) may be a switch switch that is originally installed on the indoor wall, or may be originally set to M393128 on the desk lamp 3. The switching switch is as shown in Fig. 4. For example, in the embodiment, the illumination device 1 has two kinds of illumination brightness for long-time illumination and a kind of illumination brightness with decreasing output for the user to select. Referring to FIG. 5, FIG. 6 and FIG. 7, FIG. 5 is a schematic diagram of the user operation of the first embodiment of the lighting device of the creation (10), and FIG. 6 is a schematic diagram of the operation of the maker of the coffee lighting device according to the second embodiment. The user's operation diagram of the third embodiment is the operation of the user. When the user turns on the switch unit 32 for the first time, the trigger pin Pm of the microcontroller 1211 is triggered for the first time to make the output of the microcontroller training. The pin position P_ corresponds to the input = the third Λ 至 to the pulse width modulation control unit (2), and the pulse width modulation control unit t1 122 outputs the illumination control signal to the drive circuit in response to the first dimming signal. The zenji lighting control signal is a pulse width modulation signal with a duty ratio of 100%, and the first-is lie is early, so it is driven by 1% of the power to provide the user with the first type. Luminous brightness with long-term illumination. The field user _ switch unit 32 and the switch is turned on for the second time in the other time length. P 32 (that is, when the time interval Td between the two pulse waves generated by the two switching actions needs to be smaller than the other time length), the number of times the micro control (four) 1211 _ pin pin Pin is triggered is accumulated twice. The output pin of the microcontroller ΐ2 ι## should also output the first dimming signal to the pulse width modulation control unit 122, and the pulse width modulation control unit 亓1 n , 22 corresponds to the second dimming signal. Output illumination control signal to the driving circuit 12 3, iti* n„ This illumination control signal is a pulse width M393128 degree modulation signal with a duty ratio of 75%, and the LED unit 13 is thus 75% power Driving to provide the user with the second type of illumination brightness for long-time illumination. Then, when the user turns off the switch portion 32 again and turns on the switch portion 32 for the second time period, the microcontroller 1211 The number of times the trigger pin Pin is triggered is accumulated to 3 times', so that the output pin P〇ut of the microcontroller 211 outputs the third dimming signal to the pulse width modulation control unit 122 correspondingly, and the pulse width is adjusted. The variable control unit 122 outputs according to the third dimming signal The lamp control signal is turned off to the driving circuit 123. In the first embodiment, the delayed turn-off control signal is a pulse width modulation signal with a duty ratio of 5 〇./〇, so that the power output of the driving circuit is as shown in the figure. As shown in FIG. 5, therefore, the light-emitting diode unit 13 is driven by 50% of power, and after the light-emitting diode unit 13 is driven by 50% of the power to reach the length of time, the pulse width modulation control unit 122 stops immediately. The output delays the turn-off control signal, and the LED unit 丨3 thus immediately assumes an extinguished state, thereby achieving the function of delaying the illumination off. In the second embodiment, the delayed turn-off control signal is a time length The pulse width modulation signal linearly decremented from a duty ratio of 75% to a duty ratio of 25%, so that the power output of the driving circuit is as shown in FIG. 6, and therefore, the light emitting diode unit 13 is from 75. The power drive of % is sequentially decremented to the power drive of the continent to make the light-emitting brightness of the light-emitting diode single it 13 correspondingly decrement output, and the power of the light-emitting diode is decremented by 13 to reach the time length T1 | Pulse width The modulation control unit 122 immediately stops the output of the delayed turn-off control signal, and the light-emitting diode unit 13 12 M393128 thus immediately exhibits a state of annihilation. Thus, the function of delaying the illumination can be reached. In the second embodiment, the delay is off. The lamp control signal is a pulse width modulation signal with a decreasing duty cycle. That is, the pulse width modulation control unit 122 maintains a fixed output duty between the first time and the first time point Tm. The ratio is %% of the pulse width modulation signal, and between the second time point Tm and the third time point Te, a pulse width is linearly decremented from a primary space ratio of 50% to a duty ratio of 25%. The modulation signal is such that the power output of the driving circuit is as shown in FIG. 7. Therefore, the light emission redundancy of the LED unit 13 is correspondingly decremented, and is driven by the power of the dimming diode unit 13 to be decremented. After the time length, the pulse width modulation control unit 122 immediately stops outputting the delayed turn-off control signal, and the light-emitting diode unit 13 thus immediately assumes a state of being extinguished, thereby also achieving the function of delaying the illumination off. According to the above description, the present invention allows the user to select the appropriate illuminating brightness for illumination or the illuminating brightness for decrementing output according to the actual demand by using the number of times the switch η is turned on, and due to the illumination device! With the function of delaying the illumination off, the user can leave the environment that was originally illuminated by the illumination device 1 or complete a specific transaction (such as the process of wearing shoes before going out) after stopping the use of the device (four) to effectively prevent the user from being in the dark. Dangers and accidents in the environment. The above description is only the preferred embodiment of the present invention, and is not intended to limit the scope of the patent application of the present invention. Therefore, any equivalent changes or modifications made without departing from the spirit of the present invention should be included in the present case.
