(4) The first parallel control time of the spears of the 6th time slot is 4 (as in step S517). When the "th" control unit 5 controls the second group of light-emitting diodes: as in step S519), that is, the control unit 15 controls the second (four) to be parallel (the first and the __q in the group 141, First, the first pole phantom is one... # and the first switch element S1 and S2 are turned on, and the (-) light-emitting diode module (4) in the light-emitting diode module MI is connected to the first and the H13. At this time, the turn-on voltage of the light-emitting unit 14 is Μ. S50]~S5I9 is an example of the input power supply cycle (ie, two to one hundred-ten degrees), and then the mother input cycle of the power supply. That is to say, the method is continuously repeated in this way. 叮 In addition, it is worth mentioning that when the fiber and the _ are executed, the current supplied by the control unit 15 to the light source unit 14 is reduced to the minimum required for the temple light to be 7L 14 The current, and when 8515 and %19, the control unit 15 is controlled by - and controls the current supplied by the current source 17 to the illumination to increase the current required to maintain the illumination unit 14 to emit light. An example of the fact that it can be known that during the cycle of turning in the power, when in the input The time before the peak of the power supply V3, as the input 13/20 201244541 is changed from small to large, the number of the first light-emitting unit _ in the light-emitting unit 4 is also increased in series with the first first-group 413. The light conduction of Μ is increased. On the other hand, the input voltage is changed from large to small, and the first light-emitting group 1411 and the second light-emitting group are in the 413. The multiple in parallel is used to reduce the turn-on voltage of the light-emitting unit 。. In addition, the conduction illuminance of the light-emitting unit 14 in the above-mentioned 6 is determined, and the number of the LEDs in series and/or in parallel is determined. In addition, in the above-mentioned FIG. 5, the control unit 15 is illuminating: in the polar body module 141, the light type 1412, the soil group 1411 and the second lighting group are (4). However, another actual invention of the county invention The material control system early 7015 can also judge the voltage of the input power source to determine (4) / 曰 group 141 in the first lighting group 1411 and the second lighting group, ^ or parallel. · #制单元11 is the voltage detection circuit early ^ 15 can know the pair of Ϊ 丁 2, Τ 3, D 4 of the 二 2 图 in Figure 6: according to this line with relative control Each of the light-emitting diodes is coupled. - The light-emitting group 1411 and the second light-emitting group 12 are connected in series or 3, which is a comparison chart between the light-emitting time of the present invention and the conventional light-emitting temple. FIG. 7 is a hypothesis. The invention and the conventional illumination device have a very large amount of Si? poles and the conventional illumination device emits: 22 y /, the middle waveform ρι is the input power source at - cycle time T1]; the shape diagram 'waveform P2 is the present The waveform of the illuminating conductance = m between the cycle time T1] is a waveform diagram of the illuminating conduction time Τ13 of the conventional illuminating device in this period u. Since the illumination of the present invention 14/20 201244541 ϊ = The conduction voltage of the illuminating single 7" can be adjusted, so that the illuminating time of the illuminating device of the present invention can be adjusted to be longer than the conventional one.

The illuminating device shown in Fig. 8 is the same as the illuminating device shown in Fig. 4 except that the illuminating-pole module 141 can be connected or connected in parallel or in parallel with each other. The rest is the same, and will not be described here. (Possible Efficacy of the Embodiment) As described above, the present invention can adjust the on-voltage in the light-emitting unit so that the conduction time of the light-emitting S element can be counted, so that the stroboscopic phenomenon of the light-emitting unit can be effectively reduced.
