為使熟習本發明所屬技術領域之一般技藝者能更進一步了解本發明，下文特列舉本發明之較佳實施例，並配合所附圖式，詳細說明本發明的構成內容及所欲達成之功效。 The present invention will be further understood by those of ordinary skill in the art to which the present invention pertains. .
圖1為本發明之可調光之照明裝置之方塊圖。在圖1中，可調光之照明裝置10包括一LED(發光二極體)燈具12、一電源轉換器14、一微處理器16、一感測器18及一藍牙裝置20。感測器18係一微波感測器、一紅外線感測器或一雷達波感測器。 1 is a block diagram of a dimmable lighting device of the present invention. In FIG. 1, the dimmable illumination device 10 includes an LED (light emitting diode) lamp 12, a power converter 14, a microprocessor 16, a sensor 18, and a Bluetooth device 20. The sensor 18 is a microwave sensor, an infrared sensor or a radar wave sensor.
電源轉換器14將一電源22之交流電轉換成直流電以供應至LED燈具12。微處理器16送出一亮度信號至電源轉換器14，以控制電源轉換器14供應至LED燈具12之直流電的大小，以調整LED燈具12之亮度，例如調整LED燈具12之亮度為100%的亮度、 50%的亮度或20%的亮度等等。 The power converter 14 converts the alternating current of a power source 22 into a direct current to be supplied to the LED lamp 12. The microprocessor 16 sends a brightness signal to the power converter 14 to control the magnitude of the DC power supplied by the power converter 14 to the LED lamp 12 to adjust the brightness of the LED lamp 12, for example, to adjust the brightness of the LED lamp 12 to 100% brightness. , 50% brightness or 20% brightness and so on.
感測器18感測到有物體移動(例如有人走動)時發出一感測信號至微處理器16。微處理器可設定至少一操作模式，例如在日間時段的白天模式及夜間時段的夜間模式。每一操作模式具有數個時間區段(例如5分鐘、10分鐘、20分鐘等等)，每一時間區段相應數個亮度信號之每一亮度信號(例如使LED燈具12之亮度為100%之亮度信號、使LED燈具12之亮度為50%之亮度信號、LED燈具12之亮度為20%之亮度信號等等)。亮度信號係為脈衝寬度調變(PWM)信號。 The sensor 18 senses a sensing signal to the microprocessor 16 as it moves (eg, when someone is walking). The microprocessor can set at least one mode of operation, such as a day mode during the daytime period and a nighttime mode during the nighttime period. Each mode of operation has a plurality of time segments (eg, 5 minutes, 10 minutes, 20 minutes, etc.), each brightness signal of each of the corresponding plurality of brightness signals (eg, the brightness of the LED luminaire 12 is 100%) The brightness signal, the brightness signal that causes the brightness of the LED lamp 12 to be 50%, the brightness of the LED lamp 12 to be 20%, etc.). The luminance signal is a pulse width modulation (PWM) signal.
在操作例如白天模式或夜間模式的情況，當微處理器16未接收到感測器18所送出之感測信號達某一時間區段(例如感測器18未感測到有人走動的時間達10分鐘之久)時，微處理器16送出相應達該某一時間區段之一相應亮度信號至電源轉換器14，以控制電源轉換器14供應至LED燈具12之直流電的大小，進而調整LED燈具12之相應於該相應亮度信號之亮度，例如該相應亮度信號是50%亮度信號，而使LED燈具12之亮度為50%亮度。 In the case of operating, for example, day mode or night mode, when the microprocessor 16 does not receive the sensing signal sent by the sensor 18 for a certain period of time (eg, the sensor 18 does not sense that someone is walking for a period of time) When 10 minutes), the microprocessor 16 sends a corresponding brightness signal corresponding to one of the certain time segments to the power converter 14 to control the magnitude of the direct current supplied by the power converter 14 to the LED lamp 12, thereby adjusting the LED. The brightness of the luminaire 12 corresponding to the corresponding brightness signal, for example, the corresponding brightness signal is a 50% brightness signal, and the brightness of the LED luminaire 12 is 50% brightness.
由於亮度信號係為脈衝寬度調變信號，當微處理器16送出由100%亮度信號改變為50%亮度信號，脈衝寬度調變信號的信號週期(如導通週期)並不是由100%直接變為50%，而是由100%逐漸減少至50%的信號週期，因此LED燈具12之亮度是由100%逐漸減少至50%的亮度；相對地，當微處理器16送出由50%亮度信號改變為100%亮度信號，脈衝寬度調變信號的信號週期，而是由50%逐漸增加至100%的信號週期，因此LED燈具12之亮度是由50%逐漸增加至100%的亮度。 Since the luminance signal is a pulse width modulation signal, when the microprocessor 16 sends a 100% luminance signal to a 50% luminance signal, the signal period of the pulse width modulation signal (such as the on period) is not directly changed from 100%. 50%, but the signal period is gradually reduced from 100% to 50%, so the brightness of the LED luminaire 12 is gradually reduced from 100% to 50%; in contrast, when the microprocessor 16 sends out a 50% brightness signal change For the 100% luminance signal, the signal period of the pulse width modulation signal is gradually increased from 50% to 100% of the signal period, so the brightness of the LED lamp 12 is gradually increased from 50% to 100%.
藍牙裝置20接收由外部裝置(如智慧型裝置)傳送之用以設定如上述之操作模式及其數個時間區段與數個亮度信號，並傳送至微處理器16，微處理器16在接收到操作模式及其數個時間區段與數個亮度信號後而進行更改其時間區段與亮度信號之設定。在照明裝置10中之藍牙裝置20在接收到操作模式及其數個時間區段與數個亮度信號後可發送至其它照明裝置中之藍牙裝置，如此可以透過其他藍牙裝置再進行信號之傳遞，藉以增加信號傳遞距離，而可以作群體的控制。 The Bluetooth device 20 receives an operation mode transmitted by an external device (such as a smart device) for setting the operation mode as described above and its plurality of time segments and a plurality of luminance signals, and transmits the signals to the microprocessor 16, and the microprocessor 16 receives the signals. The time zone and brightness signal settings are changed after the operation mode and its several time segments and several luminance signals. The Bluetooth device 20 in the illumination device 10 can send the operation mode and its several time segments and several brightness signals to the Bluetooth device in the other illumination device, so that the signal can be transmitted through other Bluetooth devices. In order to increase the signal transmission distance, it can be controlled by the group.
參照上述照明裝置之方塊圖以說明本發明之可調光之照明裝置的操作。 Referring to the block diagram of the illumination device described above, the operation of the dimmable illumination device of the present invention is illustrated.
圖2為本發明之可調光之照明裝置之初始狀態之流程圖。在圖2中，當打開照明裝置10之電源時，初始的亮度信號設定為100%亮度，電源供應器14依據100%亮度之亮度信號供應直流電給LED燈具12，使LED燈具12的亮度為100%的亮度(步驟S30)。接著，微處理器16進行白天模式之操作(步驟S32)。 2 is a flow chart showing the initial state of the dimmable lighting device of the present invention. In FIG. 2, when the power of the illumination device 10 is turned on, the initial brightness signal is set to 100% brightness, and the power supply 14 supplies DC power to the LED lamp 12 according to the brightness signal of 100% brightness, so that the brightness of the LED lamp 12 is 100. The brightness of % (step S30). Next, the microprocessor 16 performs an operation in the day mode (step S32).
圖3為本發明之可調光之照明裝置之白天模式之操作之流程圖。照明裝置10設定白天模式係因人們通過照明裝置10的次數相當頻繁，可讓LED燈具12的亮度等待改變的時間長，避免LED燈具12的明暗改變頻繁。 3 is a flow chart showing the operation of the daylight mode of the dimmable lighting device of the present invention. The lighting device 10 sets the daytime mode because the number of times people pass through the lighting device 10 is quite frequent, and the brightness of the LED lamp 12 can be changed for a long time, and the brightness of the LED lamp 12 is prevented from changing frequently.
在圖3中，感測器18持續感測是否有物體移動，亦即感測是否有人走動，當感測器18感測到有物體移動時，感測器18送出感測信號至微處理器16，微處理器16判斷接收到感測信號是否在白天模式的第一時間區段(本實施例之第一時間區段設為10分鐘)中(步驟S40)。若接收到感測信號是在白天模式的10分鐘內，則微處理 器16會重置第一時間區段的偵測時間(步驟S42)，接著實施步驟S40。 In FIG. 3, the sensor 18 continuously senses whether an object moves, that is, whether a person is moving, and when the sensor 18 senses that an object moves, the sensor 18 sends a sensing signal to the microprocessor. 16. The microprocessor 16 determines whether the received sensing signal is in the first time zone of the day mode (the first time zone of the embodiment is set to 10 minutes) (step S40). If the received sensing signal is within 10 minutes of the day mode, then the microprocessor The timer 16 resets the detection time of the first time zone (step S42), and then proceeds to step S40.
若微處理器16在白天模式的10分鐘內未接收到感測信號是，則微處理器16送出由100%亮度信號改變為50%亮度信號(相應第一時間區段之亮度信號)至電源供應器14，亦即微處理器16送出之脈衝寬度調變信號的信號週期是由100%逐漸減少至50%的信號週期而送至電源供應器14，電源供應器14根據逐漸減少的亮度信號供應直流電給LED燈具12，使得LED燈具12之亮度是由100%逐漸減少至50%的亮度(步驟S44)。 If the microprocessor 16 does not receive the sensing signal within 10 minutes of the day mode, the microprocessor 16 sends a 100% luminance signal to a 50% luminance signal (corresponding to the luminance signal of the first time period) to the power source. The signal period of the supply 14, which is the pulse width modulation signal sent from the microprocessor 16, is sent to the power supply 14 by a signal period which is gradually reduced from 100% to 50%, and the power supply 14 is based on the gradually decreasing luminance signal. The direct current is supplied to the LED lamp 12 such that the brightness of the LED lamp 12 is gradually reduced from 100% to 50% (step S44).
接著，感測器18在第一時間區段之後之第二時間區段持續感測是否有物體移動，當感測器18感測到有物體移動時，感測器18送出感測信號至微處理器16，微處理器16判斷接收到感測信號是否在白天模式的第二時間區段(本實施例之第二時間區段設為30分鐘)中(步驟S46)。若接收到感測信號是在白天模式的30分鐘內，則微處理器16會重置而重回到第一時間區段的偵測時間，微處理器16送出由50%亮度信號改變為100%亮度信號至電源供應器14，亦即微處理器16送出之脈衝寬度調變信號的信號週期是由50%逐漸增加至100%的信號週期而送至電源供應器14，電源供應器14根據逐漸增加的亮度信號供應直流電給LED燈具12，使得LED燈具12之亮度是由50%逐漸增加至100%的亮度(步驟S48)，接著實施步驟S40。 Then, the sensor 18 continuously senses whether there is an object moving in the second time period after the first time period. When the sensor 18 senses that there is an object moving, the sensor 18 sends the sensing signal to the micro. The processor 16, the microprocessor 16 determines whether the received sensing signal is in the second time zone of the day mode (the second time zone of the embodiment is set to 30 minutes) (step S46). If the sensing signal is received within 30 minutes of the day mode, the microprocessor 16 resets and returns to the detection time of the first time zone, and the microprocessor 16 sends a change from 50% brightness signal to 100. The signal signal period of the % luminance signal to the power supply 14, that is, the pulse width modulation signal sent from the microprocessor 16 is sent from the 50% to 100% signal period to the power supply 14, and the power supply 14 is based on The gradually increasing luminance signal supplies DC power to the LED lamp 12 such that the brightness of the LED lamp 12 is gradually increased from 50% to 100% (step S48), followed by step S40.
若微處理器16在白天模式的30分鐘內未接收到感測信號是，則微處理器16送出由50%亮度信號改變為10%亮度信號(相應第二時間區段之亮度信號)至電源供應器14，亦即微處理器16送出之脈衝寬度調變信號的信號週期是由50%逐漸減少至10%的信號週期而送至電源供應器14，電源供應器14根據逐漸減少的亮度信號 供應直流電給LED燈具12，使得LED燈具12之亮度是由50%逐漸減少至10%的亮度(步驟S50)。接著，微處理器16進行夜間模式之操作(步驟S52)。 If the microprocessor 16 does not receive the sensing signal within 30 minutes of the day mode, the microprocessor 16 sends a 50% luminance signal to a 10% luminance signal (corresponding to the luminance signal of the second time segment) to the power source. The signal period of the supply 14, that is, the pulse width modulation signal sent from the microprocessor 16, is sent from the 50% to 10% signal period to the power supply 14, and the power supply 14 is based on the gradually decreasing luminance signal. The direct current is supplied to the LED lamp 12 such that the brightness of the LED lamp 12 is gradually reduced from 50% to 10% (step S50). Next, the microprocessor 16 performs an operation in the night mode (step S52).
圖4為本發明之可調光之照明裝置之夜間模式之操作之流程圖。照明裝置10設定夜間模式係因人們通過照明裝置10的次數稀少，可讓LED燈具12的亮度等待改變的時間短，而可使照明裝置10達到節省更多電力之目的。 4 is a flow chart showing the operation of the night mode of the dimmable lighting device of the present invention. The illumination device 10 sets the night mode because the number of times the person passes through the illumination device 10 is scarce, and the time for the brightness of the LED lamp 12 to wait for change is short, and the illumination device 10 can achieve the purpose of saving more power.
在圖4中，在夜間模式中，感測器18持續感測是否有物體移動(步驟S60)，若感測器18一直未感測到有物體移動，持續實施步驟S60。若感測器18感測到有物體移動，感測器18送出感測信號至微處理器16，微處理器16接收到感測信號後，微處理器16判斷在夜間模式中此次接收到的感測信號與前一次接收到的感測信號兩者相距時間是否小於第三時間區段(本實施例之第三時間區段設為20分鐘)(步驟S62)。 In FIG. 4, in the night mode, the sensor 18 continuously senses whether or not an object moves (step S60), and if the sensor 18 has not sensed an object movement, the step S60 is continuously performed. If the sensor 18 senses an object movement, the sensor 18 sends a sensing signal to the microprocessor 16, and after receiving the sensing signal, the microprocessor 16 determines that it is received in the night mode. Whether the time between the sensing signal and the previously received sensing signal is less than the third time period (the third time period of the embodiment is set to 20 minutes) (step S62).
若此次接收到的感測信號與前一次接收到的感測信號兩者相距時間小於20分鐘，則微處理器16會重置而重回到第一時間區段的偵測時間，微處理器16送出由10%亮度信號改變為100%亮度信號至電源供應器14，亦即微處理器16送出之脈衝寬度調變信號的信號週期是由10%逐漸增加至100%的信號週期而送至電源供應器14，電源供應器14根據逐漸增加的亮度信號供應直流電給LED燈具12，使得LED燈具12之亮度是由10%逐漸增加至100%的亮度(步驟S64)，接著微處理器16實施白天模式之操作(步驟S66)。 If the received sensing signal and the previously received sensing signal are less than 20 minutes apart, the microprocessor 16 resets and returns to the detecting time of the first time segment, and the micro processing The device 16 sends a 10% luminance signal to a 100% luminance signal to the power supply 14, that is, the signal period of the pulse width modulation signal sent from the microprocessor 16 is sent from 10% to 100% of the signal period. To the power supply 14, the power supply 14 supplies DC power to the LED lamp 12 according to the gradually increasing brightness signal, so that the brightness of the LED lamp 12 is gradually increased from 10% to 100% (step S64), and then the microprocessor 16 The operation of the day mode is carried out (step S66).
若此次接收到的感測信號與前一次接收到的感測信號兩者相距時間不小於20分鐘，則微處理器16會重置而重回到第三 時間區段的偵測時間，微處理器16送出由10%亮度信號改變為100%亮度信號至電源供應器14，亦即微處理器16送出之脈衝寬度調變信號的信號週期是由10%逐漸增加至100%的信號週期而送至電源供應器14，電源供應器14根據逐漸增加的亮度信號供應直流電給LED燈具12，使得LED燈具12之亮度是由10%逐漸增加至100%的亮度(步驟S68)。 If the received sensing signal and the previously received sensing signal are not less than 20 minutes apart, the microprocessor 16 resets and returns to the third. The detection time of the time zone, the microprocessor 16 sends a 10% luminance signal to a 100% luminance signal to the power supply 14, that is, the signal period of the pulse width modulation signal sent by the microprocessor 16 is 10%. The signal period is gradually increased to 100% and sent to the power supply 14. The power supply 14 supplies DC power to the LED lamp 12 according to the gradually increasing brightness signal, so that the brightness of the LED lamp 12 is gradually increased from 10% to 100%. (Step S68).
感測器18持續感測是否有物體移動，當感測器18感測到有物體移動時，感測器18送出感測信號至微處理器16，微處理器16判斷接收到感測信號是否在夜間模式的第四時間區段(本實施例之第四時間區段設為5分鐘)中(步驟S70)。若接收到感測信號是在夜間模式的5分鐘內，則微處理器16會重置第三時間區段的偵測時間(步驟S72)，接著實施步驟S70。 The sensor 18 continuously senses whether there is an object moving. When the sensor 18 senses that there is an object moving, the sensor 18 sends a sensing signal to the microprocessor 16, and the microprocessor 16 determines whether the sensing signal is received. In the fourth time zone of the night mode (the fourth time zone of the present embodiment is set to 5 minutes) (step S70). If the sensing signal is received within 5 minutes of the night mode, the microprocessor 16 resets the detection time of the third time zone (step S72), and then proceeds to step S70.
若微處理器16在夜間模式的5分鐘內未接收到感測信號是，則微處理器16送出由100%亮度信號改變為50%亮度信號(相應第四時間區段之亮度信號)至電源供應器14，亦即微處理器16送出之脈衝寬度調變信號的信號週期是由100%逐漸減少至50%的信號週期而送至電源供應器14，電源供應器14根據逐漸減少的亮度信號供應直流電給LED燈具12，使得LED燈具12之亮度是由100%逐漸減少至50%的亮度(步驟S74)。 If the microprocessor 16 does not receive the sensing signal within 5 minutes of the night mode, the microprocessor 16 sends a change from the 100% luminance signal to the 50% luminance signal (corresponding to the luminance signal of the fourth time segment) to the power source. The signal period of the supply 14, which is the pulse width modulation signal sent from the microprocessor 16, is sent to the power supply 14 by a signal period which is gradually reduced from 100% to 50%, and the power supply 14 is based on the gradually decreasing luminance signal. The direct current is supplied to the LED lamp 12 such that the brightness of the LED lamp 12 is gradually reduced from 100% to 50% (step S74).
接著，感測器18在第四時間區段之後之第五時間區段持續感測是否有物體移動，當感測器18感測到有物體移動時，感測器18送出感測信號至微處理器16，微處理器16判斷接收到感測信號是否在夜間模式的第五時間區段(本實施例之第五時間區段設為10分鐘)中(步驟S76)。若接收到感測信號是在夜間模式的10分鐘內， 則實施步驟S68。 Then, the sensor 18 continuously senses whether there is an object moving in the fifth time period after the fourth time zone. When the sensor 18 senses that there is an object moving, the sensor 18 sends the sensing signal to the micro. The processor 16, the microprocessor 16 determines whether the received sensing signal is in the fifth time zone of the night mode (the fifth time zone of the embodiment is set to 10 minutes) (step S76). If the sensing signal is received within 10 minutes of the night mode, Then step S68 is implemented.
若微處理器16在夜間模式的10分鐘內未接收到感測信號是，則微處理器16送出由50%亮度信號改變為10%亮度信號(相應第五時間區段之亮度信號)至電源供應器14，亦即微處理器16送出之脈衝寬度調變信號的信號週期是由50%逐漸減少至10%的信號週期而送至電源供應器14，電源供應器14根據逐漸減少的亮度信號供應直流電給LED燈具12，使得LED燈具12之亮度是由50%逐漸減少至10%的亮度(步驟S78)。接著，實施步驟S60。 If the microprocessor 16 does not receive the sensing signal within 10 minutes of the night mode, the microprocessor 16 sends a 50% luminance signal to a 10% luminance signal (corresponding to the luminance signal of the fifth time segment) to the power source. The signal period of the supply 14, that is, the pulse width modulation signal sent from the microprocessor 16, is sent from the 50% to 10% signal period to the power supply 14, and the power supply 14 is based on the gradually decreasing luminance signal. The direct current is supplied to the LED lamp 12 such that the brightness of the LED lamp 12 is gradually reduced from 50% to 10% (step S78). Next, step S60 is performed.
在夜間，由於人員經過照明裝置10的次數很少，可調光之照明裝置10設定夜間模式，使偵測的時間縮短而使照明裝置10長時間處於低亮度的狀態，而可節省照明裝置10更多的電能消耗。 At night, since the number of times the person passes through the illumination device 10 is small, the dimmable illumination device 10 sets the night mode, so that the detection time is shortened and the illumination device 10 is in a low brightness state for a long time, and the illumination device 10 can be saved. More power consumption.
本發明係提供一種可調光之照明裝置及其操作方法，不是採用直接開關電源的控制方式，而是採用多段調整照明功率輸出的控制方式，以控制照明裝置的明暗度，且控制照明裝置的亮度為緩亮或緩暗，如此不會造成使用者的驚嚇畏懼，亦不會造成眼睛不適的感覺，而且可更佳節省照明裝置的電能消耗。 The invention provides a dimmable lighting device and an operating method thereof, instead of adopting a direct switching power supply control mode, a multi-stage control method for adjusting the lighting power output to control the brightness of the lighting device, and controlling the lighting device The brightness is light or dark, so that the user will not be scared and feared, and will not cause eye discomfort, and the power consumption of the lighting device can be better saved.
