Description
本發明係有關於一種發光二極體驅動裝置，特別是一種智慧型發光二極體驅動裝置。 The invention relates to a light-emitting diode driving device, in particular to a smart light-emitting diode driving device.
請參考第一圖，其係為相關技術之發光二極體模組方塊圖。一發光二極體模組90包含一發光二極體20及一發光二極體驅動電路104；該發光二極體20電性連接至該發光二極體驅動電路104。 Please refer to the first figure, which is a block diagram of a related art LED module. The LED module 90 includes a light emitting diode 20 and a light emitting diode driving circuit 104. The light emitting diode 20 is electrically connected to the LED driving circuit 104.
該發光二極體驅動電路104係用以驅動該發光二極體20；該發光二極體20的光的強度係取決於該發光二極體驅動電路104所輸出之電流；如果該發光二極體驅動電路104所輸出之電流越大，則該發光二極體20的光的強度越強；如果該發光二極體驅動電路104所輸出之電流越小，則該發光二極體20的光的強度越弱。 The light emitting diode driving circuit 104 is configured to drive the light emitting diode 20; the intensity of the light of the light emitting diode 20 depends on the current output by the light emitting diode driving circuit 104; if the light emitting diode The greater the current output by the body driving circuit 104, the stronger the intensity of the light of the light emitting diode 20; if the current output by the light emitting diode driving circuit 104 is smaller, the light of the light emitting diode 20 is light. The weaker the intensity.
然而，在上述相關技術當中，如果想改變該發光二極體驅動電路104所輸出之電流，則必須改變該發光二極體驅動電路104的硬體；如此將非常地不方便。 However, in the above related art, if it is desired to change the current output by the LED driving circuit 104, it is necessary to change the hardware of the LED driving circuit 104; this is extremely inconvenient.
尤其是，在複數之該發光二極體20被製造完成時，該些發光二極體20會依照該些發光二極體20的光學特性而被分類。 In particular, when the plurality of light-emitting diodes 20 are completed, the light-emitting diodes 20 are classified according to the optical characteristics of the light-emitting diodes 20.
如果光學特性不同的該些發光二極體20都被使用製造成相同光學 特性的該些發光二極體模組90，則部份該發光二極體驅動電路104的硬體必須改變，以達成所有該些發光二極體模組90的光學特性都相同；如此將非常地不方便。 If the light-emitting diodes 20 having different optical characteristics are used to make the same optical The characteristics of the LED module 90, the hardware of the LED driver circuit 104 must be changed to achieve the same optical characteristics of all of the LED modules 90; The place is not convenient.
再者，該發光二極體20使用越久，則該發光二極體20的光的強度越弱；而已經被焊接在一印刷電路板(第一圖未示)上的該發光二極體驅動電路104的硬體不可能再改變以增加該發光二極體驅動電路104的輸出電流。於是，不可避免地，該發光二極體20使用越久，則該發光二極體20的光的強度越弱。 Moreover, the longer the LED 20 is used, the weaker the intensity of the light of the LED 20 is; and the LED has been soldered to a printed circuit board (not shown). The hardware of the circuit 104 is unlikely to be changed to increase the output current of the LED driver circuit 104. Therefore, inevitably, the longer the light-emitting diode 20 is used, the weaker the intensity of the light of the light-emitting diode 20.
為改善上述習知技術之缺點，本發明之目的在於提供一種智慧型發光二極體驅動裝置。 In order to improve the above disadvantages of the prior art, it is an object of the present invention to provide a smart LED driving device.

該智慧型發光二極體驅動裝置10包含一微處理單元102、一發光二極體驅動電路104、一計時單元106、一溫度感測單元108、一儲存單元110、一數位多工介面112及一數位可定址照明介面(Digital Addressable Lighting Interface，通常簡稱為DALI或Digital Multiplex，通常簡稱為DMX)114。 The smart LED driving device 10 includes a micro processing unit 102, a light emitting diode driving circuit 104, a timing unit 106, a temperature sensing unit 108, a storage unit 110, a digital multiplex interface 112, and A Digital Addressable Lighting Interface (commonly referred to as DALI or Digital Multiplex, often referred to simply as DMX) 114.
該光學檢測設備30電性連接至該電腦40；該微處理單元102電性連接至該電腦40、該發光二極體驅動電路104、該計時單元106、該溫度感測單元108、該儲存單元110、該數位多工介面112及該數位可定址照明介面114；該發光二極體20電性連接至該發光二 極體驅動電路104及該計時單元106。 The optical detecting device 30 is electrically connected to the computer 40. The micro processing unit 102 is electrically connected to the computer 40, the LED driving circuit 104, the timing unit 106, the temperature sensing unit 108, and the storage unit. 110. The digital multiplex interface 112 and the digital addressable illumination interface 114; the LED body 20 is electrically connected to the light emitting diode The polar body drive circuit 104 and the timing unit 106.
該光學檢測設備30檢測該發光二極體20的光學特性之後，該光學檢測設備30傳送一光學特性信號50至該電腦40；該電腦40運算處理該光學特性信號50後，該電腦40傳送一控制信號60至該微處理單元102；該微處理單元102紀錄該控制信號60；依據該控制信號60，該微處理單元102控制該發光二極體驅動電路104；該發光二極體驅動電路104以一驅動電流116驅動該發光二極體20。 After the optical detecting device 30 detects the optical characteristic of the LED 20, the optical detecting device 30 transmits an optical characteristic signal 50 to the computer 40. After the computer 40 processes the optical characteristic signal 50, the computer 40 transmits a Control signal 60 to the micro-processing unit 102; the micro-processing unit 102 records the control signal 60; according to the control signal 60, the micro-processing unit 102 controls the LED driving circuit 104; the LED driving circuit 104 The light emitting diode 20 is driven by a driving current 116.
如前所述，在複數之該發光二極體20被製造完成時，該些發光二極體20會依照該些發光二極體20的光學特性而被分類。 As described above, when the plurality of light-emitting diodes 20 are manufactured, the light-emitting diodes 20 are classified according to the optical characteristics of the light-emitting diodes 20.
因此，該光學檢測設備30檢測該發光二極體20的光學特性，該光學檢測設備30即通知該電腦40，該電腦40運算處理該光學特性信號50後，該電腦40通知該微處理單元102，該微處理單元102即紀錄下該發光二極體20的光學特性。 Therefore, the optical detecting device 30 detects the optical characteristics of the light emitting diode 20, and the optical detecting device 30 notifies the computer 40. After the computer 40 calculates and processes the optical characteristic signal 50, the computer 40 notifies the micro processing unit 102. The micro processing unit 102 records the optical characteristics of the light emitting diode 20.
於是，當該智慧型發光二極體模組70被焊接在一印刷電路板(第二~四圖未示)時，該微處理單元102即依據該控制信號60控制該發光二極體驅動電路104以驅動該發光二極體20。而需求的光的強度、光學特性及輸出電流等等設定資訊可由該電腦40及該微處理單元102作設定處理。 Therefore, when the smart LED module 70 is soldered to a printed circuit board (second to fourth), the microprocessor unit 102 controls the LED driving circuit according to the control signal 60. 104 to drive the light emitting diode 20. The setting information of the required light intensity, optical characteristics, output current, and the like can be set by the computer 40 and the micro processing unit 102.
藉此，如果光學特性不同的該些發光二極體20都被使用製造成相同光學特性的該些智慧型發光二極體模組70，則該些發光二極體驅動電路104的硬體不必改變，即可達成所有該些智慧型發光二極體模組70的光學特性都相同；如此將非常地方便。 Therefore, if the LEDs 20 having different optical characteristics are used for the smart LED modules 70 manufactured to have the same optical characteristics, the hardware of the LED driving circuits 104 does not have to be used. By changing, it is possible to achieve the same optical characteristics of all of the smart LED modules 70; this will be very convenient.
再者，該計時單元106係用以計算該發光二極體20已使用時間； 該微處理單元102係用以累計該發光二極體20已使用時間；當該發光二極體20已使用超過一第一預定時間時，該發光二極體驅動電路104以一第一預設電流118驅動該發光二極體20，該第一預設電流118大於該驅動電流116。 Furthermore, the timing unit 106 is configured to calculate the used time of the LED 20; The micro-processing unit 102 is configured to accumulate the used time of the LED 20; when the LED 20 has been used for more than a first predetermined time, the LED driving circuit 104 has a first preset.

例如，該驅動電流116為500mA；當該發光二極體20已使用超過1000個小時，該發光二極體驅動電路104以520mA的電流驅動該發光二極體20；當該發光二極體20已使用超過5000個小時，該發光二極體驅動電路104以550mA的電流驅動該發光二極體20；當該發光二極體20已使用超過10000個小時，該發光二極體驅動電路104以570mA的電流驅動該發光二極體20。藉此，即使該發光二極體20被使用很久，該發光二極體20的光學特性可以保持穩定。 For example, the driving current 116 is 500 mA; when the LED 20 has been used for more than 1000 hours, the LED driving circuit 104 drives the LED 20 at a current of 520 mA; when the LED 20 is used The LED driving circuit 104 has driven the LED 20 at a current of 550 mA for more than 5,000 hours; when the LED 20 has been used for more than 10,000 hours, the LED driver circuit 104 The light-emitting diode 20 is driven by a current of 570 mA. Thereby, even if the light emitting diode 20 is used for a long time, the optical characteristics of the light emitting diode 20 can be kept stable.
再者，該溫度感測單元108係用以感測該發光二極體20的溫度；當該發光二極體20的溫度超過一預設溫度(例如攝氏85度)時，該發光二極體驅動電路104以一第二預設電流120(例如450mA)驅動該發光二極體20，該第二預設電流120(例如450mA)小於該驅動電流116(例如500mA)。甚至在溫度超過攝氏100度時，該發光二極體驅動電路104停止驅動該發光二極體20。 Furthermore, the temperature sensing unit 108 is configured to sense the temperature of the light emitting diode 20; when the temperature of the light emitting diode 20 exceeds a preset temperature (for example, 85 degrees Celsius), the light emitting diode The driving circuit 104 drives the LED 20 with a second preset current 120 (for example, 450 mA), and the second preset current 120 (for example, 450 mA) is smaller than the driving current 116 (for example, 500 mA). The light emitting diode driving circuit 104 stops driving the light emitting diode 20 even when the temperature exceeds 100 degrees Celsius.
該微處理單元102可為例如一微處理器，但並不限定；該計時單元106可為例如一計時器，但並不限定；該溫度感測單元108可為例如一溫度感測器，但並不限定；該儲存單元110可為例如一記憶體，但並不限定。 The micro-processing unit 102 can be, for example, a microprocessor, but is not limited; the timing unit 106 can be, for example, a timer, but is not limited; the temperature sensing unit 108 can be, for example, a temperature sensor, but It is not limited; the storage unit 110 can be, for example, a memory, but is not limited.
本發明之功效在於，該光學檢測設備30檢測該發光二極體20的光學特性之後，該光學檢測設備30傳送該光學特性信號50至該電腦 40；該電腦40運算處理該光學特性信號50後，該電腦40傳送該控制信號60至該微處理單元102；該微處理單元102紀錄該控制信號60；依據該控制信號60，該微處理單元102控制該發光二極體驅動電路104；該發光二極體驅動電路104以該驅動電流116驅動該發光二極體20。 The effect of the present invention is that after the optical detecting device 30 detects the optical characteristics of the light emitting diode 20, the optical detecting device 30 transmits the optical characteristic signal 50 to the computer. After the computer 40 processes the optical characteristic signal 50, the computer 40 transmits the control signal 60 to the micro processing unit 102; the micro processing unit 102 records the control signal 60; according to the control signal 60, the micro processing unit The LED driver circuit 104 is controlled by the LED driver circuit 104. The LED device 20 drives the LED 20 with the driving current 116.
藉此，如果光學特性不同的該些發光二極體20都被使用製造成相同光學特性的該些智慧型發光二極體模組70，則該些發光二極體驅動電路104的硬體不必改變，即可達成所有該些智慧型發光二極體模組70的光學特性都相同。再者，即使該發光二極體20被使用很久，該發光二極體20的光學特性可以保持穩定。再者，本發明可保護該發光二極體20免於過熱。 Therefore, if the LEDs 20 having different optical characteristics are used for the smart LED modules 70 manufactured to have the same optical characteristics, the hardware of the LED driving circuits 104 does not have to be used. By changing, it is possible to achieve the same optical characteristics of all of the smart LED modules 70. Furthermore, even if the light-emitting diode 20 is used for a long time, the optical characteristics of the light-emitting diode 20 can be kept stable. Furthermore, the present invention can protect the light emitting diode 20 from overheating.
