該第一電阻器5電連接於該電子安定器8的該第一電極L1及該第二電極L2之間。該第二電阻器6電連接於該電子安定器8的該第三電極R1及該第四電極R2之間。更詳細地說，該第一電阻器5所具有的電阻值大小相關於該第一預熱電壓的電壓值與該第一預熱電流的電流值之間的比值。該第二電阻器6所具有的電阻值大小相關與該第二預熱電壓的電壓值與該第二預熱電流的電流值之間的比值。在本實施例中，該第一預熱電壓等於該第二預熱電壓等於3.6伏特(V)，該第一預熱電流及該第二預熱電流必須小於360毫安培(mA)，因此，該第一電阻器5的電阻值等於該第二電阻器6的電阻值且都大於10歐姆，例如都是200歐姆，但不在此限。The first resistor 5 is electrically connected between the first electrode L1 and the second electrode L2 of the electronic ballast 8. The second resistor 6 is electrically connected between the third electrode R1 and the fourth electrode R2 of the electronic ballast 8. In more detail, the resistance value of the first resistor 5 is related to the ratio between the voltage value of the first preheating voltage and the current value of the first preheating current. The resistance value of the second resistor 6 is related to the ratio between the voltage value of the second preheating voltage and the current value of the second preheating current. In this embodiment, the first preheating voltage is equal to the second preheating voltage is 3.6 volts (V), the first preheating current and the second preheating current must be less than 360 milliamps (mA), therefore, The resistance value of the first resistor 5 is equal to the resistance value of the second resistor 6 and is greater than 10 ohms, such as 200 ohms, but not limited to this.

當該電子安定器8分別產生該第一預熱電壓及該第二預熱電壓，進而分別產生該第一預熱電流及該第二預熱電流時，該第一預熱電流由該第一電極L1及該第二電極L2之其中一者，流經該第一電阻器5，再流進該第一電極L1及該第二電極L2之其中另一者，而不會流經該第一整流電路2，該第二預熱電流由該第三電極R1及該第四電極R2之其中一者，流經該第二電阻器6，再流進該第三電極R1及該第四電極R2之其中另一者，而不會流經該第二整流電路3。因此，該第一電阻器5及該第二電阻器6的設計能夠保護該電子安定器8及該發光二極體燈管1，而不會受到預熱電流的損壞。When the electronic ballast 8 generates the first preheating voltage and the second preheating voltage, respectively, and then the first preheating current and the second preheating current, respectively, the first preheating current is generated by the first One of the electrode L1 and the second electrode L2 flows through the first resistor 5 and then flows into the other of the first electrode L1 and the second electrode L2 without flowing through the first In the rectifier circuit 2, the second preheating current flows through the second resistor 6 from one of the third electrode R1 and the fourth electrode R2, and then flows into the third electrode R1 and the fourth electrode R2.

再者，當該發光二極體單元4的該等發光二極體導通發光時，該導通電流是由該電子安定器8的該第一電極L1及該第二電極L2之其中一者流出，經由該發光二極體單元4的該第一端及該第二端，再流入該電子安定器8的該第三電極R1及該第四電極R2之其中一者，或者，該導通電流是由該電子安定器8的該第三電極R1及該第四電極R2之其中一者流出，經由該發光二極體單元4的該第一端及該第二端，再流入該電子安定器8的該第一電極L1及該第二電極L2之其中一者。換句話說，該導通電流並不會流經該第一電阻器5及該第二電阻器6，也就是說，該第一電阻器5及該第二電阻器6的設計在該發光二極體單元4正常發光時，並不會增加額外的功率損耗。Furthermore, when the light-emitting diodes of the light-emitting diode unit 4 are turned on to emit light, the on-current is flowing from one of the first electrode L1 and the second electrode L2 of the electronic ballast 8, Via the first end and the second end of the light-emitting diode unit 4, and then flows into one of the third electrode R1 and the fourth electrode R2 of the electronic ballast 8, or the on-current is determined by One of the third electrode R1 and the fourth electrode R2 of the electronic ballast 8 flows out, flows through the first end and the second end of the light emitting diode unit 4 and flows into the electronic ballast 8 One of the first electrode L1 and the second electrode L2. In other words, the on-current does not flow through the first resistor 5 and the second resistor 6, that is, the design of the first resistor 5 and the second resistor 6 is on the light emitting diode. When the body unit 4 emits light normally, no additional power loss is added.

綜上所述，藉由電連接於該第一電極L1及該第二電極L2之間的該第一電阻器5，及電連接於該第三電極R1及該第四電極R2之間的該第二電阻器6，使得當該電子安定器8產生該第一預熱電流及該第二預熱電流時，該第一預熱電流及該第二預熱電流分別流經該第一電阻器5及該第二電阻器6，而不會流入該第一整流電路2及該第二整流電路3，進而保護該電子安定器8及該發光二極體燈管1不會受到損壞，再者，在該發光二極體單元4正常發光時，該導通電流也不會流經該第一電阻器5及該第二電阻器6，而不會增加功率的損耗，故確實能達成本發明的目的。In summary, the first resistor 5 is electrically connected between the first electrode L1 and the second electrode L2, and the first resistor 5 is electrically connected between the third electrode R1 and the fourth electrode R2.
