In this embodiment, when the first lamp failure occurrence point 332 occurs, the output voltage (waveform, but the first lamp 1〇4) continues to be continued on the second lamp tube 1〇4. There will be no current flowing (the waveform initiates the first decision circuit corresponding to the first lamp 104 to turn off the command signal 338 (for example, the 20080975277 13419twf-0P.doc/006 judgment signal when it is determined to be turned off), the second lamp After the control circuit 148 of the tube 144 receives the shutdown command signal 338, the output of the second converter 142 is stopped, so that the second lamp 144 no longer has current (waveform 342) and voltage (waveform 340), so the corresponding second is activated. The second determining circuit 152 of the lamp 144 outputs a closing command signal 344. The control circuit 278 of the third lamp 274 stops the output of the third converting piano 272 after receiving the closing command signal 344, so that the third lamp 274 no longer has The current (waveform and voltage (waveform 346), therefore, activates the second decision circuit 282 corresponding to the third lamp 274 to output the close command signal 35. The first control circuit 108 stops the first command after receiving the close command signal 35. = f output, making the first The voltage signal (waveform 334) of the lamp 1 〇 4 is reduced to zero. Referring to FIG. 4 ′, the actual circuit of the dual-lamp f-linked protection device according to the first embodiment of the present invention is disclosed. 4 is only one of the exemplary circuits of the present invention, and is not limited thereto. In FIG. 4, it includes a lamp, and the fluorescent module 4G can include, for example, a conversion. The circuit 4〇8, the feedback compensation circuit 414, such as the 勹虹一和门 420, and the lamp module 42 can be used to determine the circuit: device 2: light tube 444, detection circuit 45 〇, complement =, After changing the description of the first embodiment of the present invention, the second embodiment and its special application will be described next to 200809752) 77 13419twf-0P.doc/006. At the same time, a first control circuit 8 for driving the first source supply 80 of the first load 820, a first == and a first detection module 830 are formed by referring to FIG. (As shown in Fig. 8a) respectively, the numbers 6〇8, 6〇2 and 6〇6 in the field 6A are similarly constructed to be the second power source of the drive-second load 820. The supplier, the control circuit 800, the second converter 81, and the second module 830' (shown in FIG. 8A) correspond to the reference numerals 648, 642 and 646, respectively. It can be seen from FIG. 6A that the linkage signal from the first: control circuit 608 is the first or second detection module 5〇6, 546 as shown in FIG. 5a_5d. The linkage signal can be - frequency synchronization. The signal, the dimming signal or the "soft", in this embodiment, may also be called a command, a signal because of the linkage signal. In FIG. 8A, a first and second control circuit 8A, 8A includes a frequency generator 801 (801,), a PWM circuit 8〇2 (8〇2'), and a protection circuit 803. (803,), a drive circuit 8〇4 (8〇4,) and a dimming circuit 805 (805'). The first power supply 8 () is coupled to the second power supply 80 via the coupling between the dimming circuit 805 and its corresponding circuit 8〇5. The dimming circuit 8〇5 generates a dimming signal to the driving circuit 8〇4’ according to the illuminating signal of the dimming circuit 805. In this case, the dimming signals of the dimming circuits 805 and 805 have a time delay t between them as shown in Fig. 8A. As a result, the entire power supply (including the first and second power supply) 200809752) 77 13419twf-〇pd〇c/〇〇6 final light-emitting diode has a luminous frequency twice that of the first light The diode (or the second light-emitting diode) is as shown in Fig. 8B, thereby achieving a reduction in the scintillation function due to the dimming effect. Fig. 6B is a circuit block diagram showing a power supply interlocking operation device according to another variation of the second embodiment of the present invention. Figure 6A differs from Figure 6B in that the latter is capable of two-way communication between the two control circuits 608 and 648. Figure 6C is a block diagram showing the operation of a three-power supply interlocking operation device in accordance with another variation of the second embodiment of the present invention. This embodiment is similar to the embodiment of the figure except that a second power supply module 67 for driving a third load 674 is used. The third power supply module 670 includes: a third control circuit 6-78, a third converter 672, and a third detection 67=the second power supply module 67. The operation and function are similar to The second power supply module 64 is. Therefore, the detailed description will not be repeated here. Similarly, the embodiment of Fig. 6D is similar to the embodiment of Fig. 6B except that a third power supply module 67 () for driving a third load = 4 is used. Therefore, the detailed description will not be repeated here. Referring to FIG. 7A, the same components as FIG. 6A are included, such as a first and a second control circuit 7〇8 and 748, a first and a second converter 7〇2 and 742, and a first A second load 7〇4 and 744 and a first and a second detecting module 7〇6 and 7 are used. However, FIG. 7A discloses a linkage signal from the first converter 7〇2, rather than from the first control circuit 6〇8 as shown in FIG. 6A. Please refer to FIG. 7B and FIG. 9 simultaneously. FIG. 7B discloses that the first and second transitions 200809752) 77 13419twf-〇pd〇c/〇〇6 β 7 0 2 and 7 4 2 can output the linkage signals to their corresponding ones. The control circuits 708 and 748 are capable of modulating the operating state of the other power supply (e.g., IV) according to the state of the power supply. Money barriers can be seen as anomalies in current or power. Figure 9, circuit block diagram is the same as Figure 8A. Therefore, the description of the same elements is not repeated. It should be noted that the circle number N is used to represent the detector used to detect the output power of an inductor L. If the conversion benefit 910 and a second converter 910 generate a short leakage current (which may be caused by damage to the converter), the power supplied by the first power supply 90 is reduced, for example, from 100 watts. (W) dropped to 50 amps ^ ^ (10) / second brother two power supply 9 〇, still provide 〒. Since the brother-converter 91〇 and the second converter 91=protect: vine, the road 903 and its corresponding part 9〇3, the consuming phase; = haidi-one converter 91 〇 sends a linkage signal to the first The second turn Γ ο " :: power supply 9 〇, the power provided can be from the first -i Γ1. Because 1 ^, the second power supply 90, and:, the same power supply of the power supply 90. Conversely, If the abnormality of the power reduction occurs in the first: drag f supply is 90', the second 9Γ sends the linkage signal to the first control circuit 900 == the power provided by the power supply 90 is reduced from the reward to the drive. For the second embodiment, in addition to the additional 7 Α and the similar three power supply of Fig. 7 , and the figure - J77 13419twf-0P.d〇c / 006, please refer to FIG. 10, which discloses a second according to the present invention. One of the embodiments is a ballast state. The ballast includes a first power supply 1 (8) and a second power supply 100. The power supply 1 and 1 further include a control circuit 1 〇 and 1 〇〇〇'. Each control circuit 1 1000 and 1000' further includes a frequency generator 1001 (1001,), a drive Circuit 1〇04 (1004') and a preheating circuit 1002 (1002,). The frequency generator 1001 (1001') functions once the heat lamp (or LED) is preheated by the circuit 1002 (1002'). When heated to start, the frequency of the preheating circuit is converted to a normal operating frequency. Generally, the control circuits 1000 and 1000' require an external resistor or capacitor to set the warm-up time and the preheating frequency. In FIG. 10, since the preheating % and the preheating frequency can be set by the linkage between the control circuits 1000 and 1000 due to the coupling between the frequency generators, the external electrical appliances or capacitors are not required. Therefore, the structure of the ballast is simplified. The invention also provides a power supply linkage control method for controlling the operation of a power supply linkage operating device 50, 60 and 70. 60 and 70 include a first power supply 504, 6〇4 and 7〇4 and a second power supply 440, 640 and 740 respectively supplying power to the load 5〇6, 646 and 746'. The method includes the first Power supply a first power supply signal, the first power supply signal indicating a power supply state of the first power source s 504, 604, and 7.4; and the second "source provider" determining the second power according to the first power supply signal 377 13419iwf-0P.doc/006 200809752 The power supply status of source providers 440, 640 and 740. Another power supply linkage operation method may include: providing a first linkage operation signal generated by the first power supply; and the second power supply is controlled according to the first linkage operation signal The second power supply provides power. Moreover, the first linked operation signal may be a frequency synchronization signal, a dimming signal, or a soft start signal. The second power supply 440, 640 and 740 can provide a second linkage signal, and the power supply 504, 604 and 704 can control the operation of supplying power according to the second linkage signal.
