New description: [New technical field] This creation is about a kind of driving device, and especially related to an auto-restart and auto-recovery function. A driving device for a light emitting diode and a light source device using the same. [Prior Art] Light Emitting Diodes (LEDs) are characterized by small size, power saving, and durability, and the cost benefits are reduced due to the increased luminous process and production yield. Therefore, the light-emitting diode has gradually become the most influential light source of the new generation, and it is widely used in various terminal equipment and lighting fields. In today's LED driving technology, the LEDs are often driven at a constant current. Because once the drive current exceeds the rating of the light-emitting diode, it will easily cause the light-emitting diode to burn out. Therefore, many drive circuits and drive chips dedicated to the secondary and secondary bodies have emerged. When the chip is driven on the actual device, it is usually added with open circuit protection, overvoltage protection, and other road protection measures. #这'In the LED _ terminal open circuit or short circuit, or drive the chip side to its own fault and can not drive the LED 2 = the mobile chip will be sent through the faulty terminal - the fault signal and immediately stop ^ power supply 'Avoiding the circuit components of the driver chip or the light-emitting diodes can substantially protect and extend the M422264 for driving the chip and the light-emitting diode. 100-11-16 However, most of the driver chips today cannot restart the power supply when detecting a fault. If the fault is eliminated, or when the fault is removed (for example, the faulty LED is replaced), the drive chip cannot automatically return to the original drive state. In addition, a driver chip having the above-described automatic restart or automatic recovery function is expensive to purchase. In view of this, how to realize the automatic reset and auto-recovery function of the LED driving technology with a simple circuit architecture is an urgent and demanding development direction in this field. [New content] The present invention provides a driving device and a light source device for a light-emitting diode, which can realize an automatic restart and an automatic recovery function by using a signal generated by driving a chip towel end. The present invention proposes a driving device for a light-emitting diode comprising a switching unit, a driving unit and a driving unit. The switch input of the switch unit knows to receive the DC power, the control end of the switch unit receives a switching signal, and the switch unit switches the signal according to the switch. The driving unit is coupled to the transmission end of the switching unit, and the driving unit includes a power input terminal and a serial terminal. The _ unit receives this DC power through the generator terminal to drive the Wei diode unit. Navigation, when it is unable to drive the LED diode single, the _ unit is enabled through the faulty terminal - the fault signal. The _(4) single-domain that is connected to the drive unit is used to receive the fault signal to disable the switching signal, causing the unit to stop providing the DC-driven unit. 5 100-11-16 ^ In one embodiment of the present invention, the switch unit includes a first transistor, and the first end thereof receives the DC power source as a switch input terminal, and the second end of the transistor is coupled to The power wheel of the driving unit is used as a transmitting end, and the control end of the first transistor receives the switching signal. In an embodiment of the present invention, the fault control unit includes a fault judging unit and a switching unit. When the fault signal is enabled, the fault judging unit pulls down the reference signal to the ground voltage. The switching unit coupled to the fault judgment unit will switch the floating connection to disable it when the reference signal is pulled down to the ground voltage. In one embodiment of the present invention, the fault determining unit includes a second transistor, the first end of which is coupled to the ground, the second end of the second transistor generates the reference signal, and the second The control terminal of the crystal receives the fault signal: In an embodiment of the present invention, the switching unit includes a third transistor, the first end of which is coupled to the ground, the second end of the third transistor generates the switching signal, and the third transistor The control terminal receives the above reference signal. In an embodiment of the present invention, the switching unit further includes a fifth resistor and a sixth resistor. The first end of the fifth resistor receives the DC power source, and the second end of the fifth resistor and the first end of the sixth resistor are coupled to the control end of the third transistor. The second end of the sixth resistor is coupled to the ground. In addition, the switching unit further includes a second capacitor, the first end of which is coupled to the control terminal of the third transistor, and the second end of the second capacitor is coupled to the ground. M422264 100-11-16 From another point of view, the present invention proposes a light source device comprising: a light emitting diode unit and a __ driving device. The driving diode device is driven by a power supply, and the driving device includes a switching unit, a driving unit and a driving unit. The switch input end of the switch unit receives the receive-switch signal of the control terminal of the DC switch unit, and the switch unit $== the change signal provides the money (4) to the transmission end. The shaft unit is reduced to the transmission end of the open ^, and the driving unit includes - the power input terminal and a ^. The driving unit receives the DC power through the electric thin terminal to drive the polar body unit. Moreover, when the LED unit cannot be driven, the drive enables a fault signal, and is connected to the drive unit and the switch: the switch: ===::: can switch the signal. For the remaining implementation details of the light source device, please refer to曰 Based on the above, the driving device of the present embodiment will determine whether the hybrid DC power and the moving unit are restarted according to whether the number is enabled or not, and thus the fault signal is still output after the automatic double motion, and the automatic restart is continued. 'Until the cause of the fault is removed (for example, after the pole is replaced), it will drive the function of restoring the illumination again. The above-mentioned features and advantages of the present invention can be described in detail, and the details of the above-mentioned features can be explained in detail, such as 'The following 7 M422264 100-11*16 【Embodiment】 With reference to the exemplary embodiments of the present invention, examples of the exemplary embodiments are illustrated in the accompanying drawings. In addition, wherever possible, the same reference numerals in the FIGS. Most of the LED driver wafers have the function of self-fault detection and stop driving the LEDs in the event of a fault to protect the circuit components in the driver wafer and prevent the LEDs from burning out. For example, most of the driver chips can detect whether the two ends of the LED are open or shorted (that is, open circuit protection), and also have overvoltage protection and over-current protection of the LEDs. Circuit protection measures allow these driver chips to output a fault signal at their faulty terminals. However, compared to self-detection detection, most of the driver chips rarely have automatic restart or automatic recovery. Therefore, the focus of the present embodiment is that the driving device of the LED can use a driving chip with fault detection, and a few circuit components to realize automatic restart and automatic recovery. In other words, the driving device of the present embodiment utilizes the fault signal generated by the faulty end of the driving chip to automatically restart it when the fault signal is enabled to realize the functions of automatic restart and automatic recovery. An embodiment will be described below to explain in detail the lighting arrangement of the light-emitting diode according to the present invention. ® 1 is a block diagram illustrating a light source apparatus 100 in accordance with the present invention. The light source device 1A includes a light emitting diode unit 110 and a constant current driving circuit 12A. In this embodiment, the light emitting diode 110 can be a light emitting diode string (LED string) composed of a plurality of light emitting diodes. In other words, the light emitting diode unit 110 is composed of, for example, a plurality of light emitting diodes 112 connected in series. As shown in Fig. 1, the driving device 115 is coupled to the light emitting diode unit 11'' and is adapted to drive the light emitting diode unit 110. The drive unit 115 includes a switch unit 130, a drive unit 140, and a fault control unit 15A. In the embodiment, the driving device 115 further includes a DC power supply 12 〇, and the DC % source supply 120 is used to provide a DC power supply DC_P. In this embodiment, the DC power supply 120 can be implemented by using a full-bridge rectifier in combination with an AC power source, and can also output a DC power supply DC_P through a resistor, a capacitor, and a Zener diode. The mountain switch unit 13A includes a switch input terminal SIP, a transmission terminal TP, and a control terminal CP. The switch input terminal SIP receives the DC power supply Dc_p, the control terminal CP, and receives the switching signal CS. Therefore, the switch single illusion 3 〇 is based on the switching signal cs: straight: L 1 source DC-P is supplied to the transmission terminal τρ. In this embodiment, when the switch is enabled, the switch unit 130 turns on the switch input terminal SIP = the output terminal TP to provide the DC power source DC_p to the transmission terminal τρ. Phase, when the switching signal cs is disabled, the switching unit 130 will turn off the SIP and the transmitting terminal τρ to stop providing the direct transmission port. Driven to the transmission terminal τρ of the switching unit 130. Example t, the power wheel human end Vee and the fault end Fault. In the present embodiment, the driving unit HG includes a light-emitting diode drive with a faulty end 100-11-16 = piece (not drawn). The faulty end of the light-emitting diode driving crystal moon is the faulty end of the driving unit H0. The fault is generated, and the power supply terminal of the LED driving chip is the power input terminal Vcc of the driving unit 140. Therefore, the driver unit 140 can receive the DC power source DC_P through the power input terminal Vcc and the transmission terminal TP of the switch unit 130 to drive the LED unit 11A. Moreover, when the fault is detected, the driving unit 140 cannot drive the light-emitting diode single το 110, so that the fault signal FS is enabled through the faulty end, and the fault is detected, and the light-emitting diode cannot be driven. The case of the body unit 110' is the circuit system and the health measures provided in the light-emitting diode driving chip in the driving unit 14G, for example, the two ends of the light-emitting diode, the open circuit protection or the bribe, overvoltage and over Current protection.., etc. Therefore, the side fault type (4) should be determined by the automatic fault side function in the light emitting diode driving chip in the driving unit 140, and the embodiment is not limited thereto. A fault control unit 150_ is connected to the fault end Fault of the drive unit 140 and the control terminal cp of the switch unit 13A. So when the drive unit is just

In this case, the fault control unit 150 includes a fault judging unit 16 and a switching unit 17A. When the fault signal FS is enabled, the fault judging unit 16 will pull the reference signal to the ground 1 voltage GND% to replace the unit 17 〇贞彳 接 故障 判断 & & 接收 接收 接收 接收 接收 接收 接收 接收 接收 接收 接收 接收 接收 接收 接收 接收 接收 接收 接收 接收 接收 接收 接收And when the reference signal RS is pulled down to the ground M422264 100-11-16 voltage GND, 'the switching signal Cs is floated, so that the switching signal cs can be enabled. In contrast, when the fault signal FS is disabled, the fault judging unit _ floats the reference signal RS. When the reference signal Rs is floating, the switching unit 170 grounds the reference signal Rs to enable the switching signal CS. Based on the above, when the light source device 100 is operating normally, due to the driving unit 140, the early Fauit does not enable the fault signal FS, so the switching unit 170 continues to enable the switching signal CS, and the switching unit 13 continues to DC. The power supply DC_P is supplied to the transmission terminal τρ to keep the drive unit in operation. On the other hand, when the LED driving chip in the driving unit 14 detects a fault, the driving unit 14 transmits and activates the fault signal FS through the fault terminal Fault, and the fault control unit 15 thus switches the signal. The CS disables, causing the switch unit 13 to stop supplying the DC voltage DC_p to the transmission terminal TP, so that the drive unit 140 cannot continue to operate. At this time, since the driving unit 140 has no power supply to continue operation, the driving unit 140 returns to the initial disabled state (for example, logic, 〇, by the fault signal fs outputted through the fault terminal]pault. Because the P early FS is disabled, the fault control unit 150 will re-convert the switching signal cs from the original disable to enable, and the switch unit 13 re-supplies the DC power supply DC_P to the transmission terminal τρ, thereby implementing the driving unit. The automatic restart of the 140. In view of this, compared with the previous drive technology, since the conventional LED driver chip detects the fault, it will suspend the drive to send the M422264 100-11-16 optical diode. And maintain this state until the user manually turns off the power of the light source device. In other words, the conventional light-emitting diode drive wafer cannot be automatically restarted after detecting a fault. The light source device 100 and the driving device 115 thereof according to the embodiment of the present invention are restarted by the above actions. Further, if the driving unit 14 is in the automatic weight After the startup continues to output (or enable) the fault signal ^^, the drive device 115 will continue to automatically restart until the cause of the fault is eliminated (for example, after the user replaces the faulty LED unit 11 ()) The driving device 115 drives the LED unit 11A again, so that the light source device 100 can automatically restore the illumination and realize the function of automatic recovery. For the detailed description of the present embodiment, please refer to FIG. 2, and FIG. 2 is in accordance with this embodiment. The first embodiment of the invention illustrates a circuit diagram of a light source device 1. The driving unit 140 includes a driving chip 21A having a fault of $Fault, and the faulty end of the driving wafer 210 is electrically connected to the fault end of the driving unit 14A. In this embodiment, the model of the driving chip 21A may be the light emitting body driving chip EM8800. However, as long as the LED driving chip with the automatic error detecting function can be described in the present embodiment. The wafer 210 is driven, so the present creation is not limited thereto. As shown in Fig. 2, the switching unit 130 mainly includes a transistor. The crystal may be one of a bipolar junction transistor (BJT) or a MOS field effect transistor (M0SFET), and those skilled in the art should be able to easily replace each other, and will not be described again. In the transistor Q1, an NPN bipolar junction transistor is taken as an example. The first end (emitter terminal) of the transistor Q1 receives the DC power supply DC-p as an open 12 M422264 100-11-16 an input % SIP, electricity The second terminal (set terminal) of the crystal qi is connected to the power input terminal Vcc of the driving unit 14〇 as the transmission terminal τρ. The control terminal (base terminal) of the transistor Q1 can receive the switching signal CS. The barrier determining unit 160 mainly includes a transistor Q2, and here, an example of a transistor Q is used as a transistor. The first terminal (source terminal) of the transistor Q2 is coupled to the ground terminal to receive the ground voltage gnd, and the second terminal (汲 terminal) of the transistor Q2 generates the reference signal scale 8. The control terminal (gate terminal) of the transistor q2 receives the fault signal FS. The switching unit 17A mainly includes a transistor Q3 and resistors R5 to R6. The first terminal (source terminal) of the transistor φ is connected to the ground terminal to receive the ground voltage GND'. The second end of the transistor q3 (not extreme) A switching signal cs is generated and the control terminal (gate terminal) of the second transistor receives the reference signal rs. The first end of the resistor R5 receives the DC power source D c_ρ, and the second end of the resistor R5 is coupled to the control terminal of the transistor Q3 and the first end of the resistor R6. The second end of the resistor R6 is coupled to the ground. In order to implement the present embodiment in the actual circuit, the switch unit 130 of the present embodiment further includes resistors R1 R R2, and the fault judging unit further includes resistors R3 R R4 and capacitor C. The younger unit further includes a capacitor C2 and a resistor R1. 〜R4 and capacitors C1 to C2 may have corresponding impedance values and capacitance values depending on the processes and characteristics of the transistors q1 to q3, and the resistors R1 to R4 and the capacitors are adjusted or added and removed according to the requirements of the embodiment. The first end of the resistor R1 is lightly connected to the first end of the transistor Q1, and is electrically connected to the control terminal of the second terminal of the R1 and the first end of the resistor Μ. The control of the transistor Q1 can receive the switching signal CS through the second end of the second resistor R2 13 100-11-16, so the second end of the second resistor R2 is also the control terminal CP. The first ends of the resistors R3, R4 and C1 are coupled to the transistor (the control terminal of J2) and the second ends of the resistor R3 and the capacitor C1 are coupled to the ground. The control terminal of the transistor Q2 is transmitted through the resistor R4. The second end receives the fault signal FS. The first end of the capacitor C2 is coupled to the control end of the transistor Q3, and the second end of the capacitor C2 is coupled to the ground end. The actuation process of the light source device 1〇〇 of FIG. 2 is described herein. When the DC power supply 120 provides the DC power supply DC_P and the switching signal CS is in a preset enable state (for example, in this embodiment, the enable state of the switching signal CS is to set the switching signal CS to the ground voltage GND), The crystals Q1 and Q3 are respectively turned on due to the voltage dividing effect of the resistors R1 to R2 and the resistors R5 to R6, respectively, and the control terminal CP is coupled to the ground terminal, and the emitter terminal of the conductive crystal Qi (ie, the switch input terminal SIP) and The collector terminal (i.e., the transmission terminal τρ) is thereby provided. The transistor Q1 supplies the DC power source DC-P to the power input terminal Vcc' of the driving chip 21A to drive the LED unit 14A. However, when driving When the chip 210 detects a fault, it passes through the fault end Fault. The signal FS is converted to enable (for example, logic "1") by the disable (for example, logic, 〇, 。). The control terminal of the transistor Q2 in the fault judging unit 160 receives the enabled fault signal FS. The source terminal of the transistor Q2 is electrically connected to the 汲 terminal, so that the reference signal RS is pulled down from the original floating connection to the voltage GND' so that the control terminal of the transistor Q3 is grounded. Thereby, the transistor q3 in the switching unit 170 is switched. From the original conduction state transition state, the state is changed from the original ground voltage GND to the floating state. Based on the above action, the switch unit 13〇M422264 100-11-16: the electric body Q1 will Since the emitter end and the base end are both DC power source = the state of the drum from the county's test secret county, and stop the DC power supply DC-P to the drive wafer 21 〇 mc at this time, since the drive wafer 210 does not have a power source, The fault signal will return to the initial disable state (logic, 『). As can be seen from the above, the transistor Q2 is thus switched from the on state to the off state, and the transistors Q1 and f Q3 are thus switched from the off state to the on state. To renew The power supply DC-P is directly grasped into the driving chip 21A of the driving unit 14A, thereby realizing the functions of automatic restarting and automatic recovery. The above embodiments all illustrate that the light source for driving the single light-emitting diode unit no is not provided. In this embodiment, a plurality of driving splits 115 conforming to the present invention can also be utilized to form the light source device 300 of FIG. 3. FIG. 3 illustrates a light source device according to another embodiment of the present invention. As shown in FIG. 3, the light source device 300 has a plurality of driving devices 115 for simultaneously driving a plurality of light emitting diode units 110, and each of the DC power sources DC: P for driving the cracks 115 can be uniformly supplied by a DC voltage. 32 is supplied. Therefore, the light source device 300 can be, for example, a luminaire that simultaneously drives a plurality of light-emitting diode lamps. In summary, the driving device of the present embodiment determines whether to supply DC power to the driving unit according to whether the fault signal is enabled, thereby automatically restarting the driving unit. In other words, when the fault signal generated by the driving unit is enabled, the driving device stops supplying the DC voltage to the driving unit, and since the driving unit has no power supply, the fault signal returns to the initial state (that is, the disabled state). . Therefore, because the fault signal is disabled 15 M422264 100-11-16, the drive will re-provide DC power to the drive unit, thus implementing the automatic restart function. 0 In addition, if the drive unit still outputs a fault after the automatic restart, it will continue to restart automatically until the cause of the fault is removed (for example, after the replacement of the early LEDs), the light will be driven again. The polar unit 'automatically restores its illumination function, thus achieving automatic recovery. Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention to anyone having ordinary knowledge in the art, and may make some changes and reliances without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this creation is subject to the definition of the scope of the patent application attached.
