The specific embodiment
See also Fig. 1 and shown in Figure 2, find out that by knowing among the figure Multifunctional LED substrate of the present invention has circuit substrate 1, is packaged with light-emitting diode (LED) module 2 on the circuit substrate 1, wherein:
This circuit substrate 1 is provided with first bridge rectifier 3 and second bridge rectifier 4; First bridge rectifier 3 is provided with diode D1, D2, D3, the D4 of four connections; And the connected mode of diode D1, D2 and diode D3, D4 is opposite; Make between diode D1, the D2 and diode D3, D4 between be formed with one group of first load node 31, and be formed with one first power supply node 32 between the diode D1, D3 and between the diode D2, D4; Second bridge rectifier 4 is provided with diode D5, D6, D7, the D8 of four connections; And the connected mode of diode D5, D6 and diode D7, D8 is opposite; Make between diode D5, the D6 and diode D7, D8 between be formed with one group of second load node 41; And be formed with one group of second source node 42 between the diode D5, D7 and between the diode D6, D8, and first power supply node 32 and second source node 42 are for being parallelly connected shape; This diode D1, D2, D3, D4, D5, D6, D7, D8 can be Zener diode, like silicon reference diode (Zener diode).
This light-emitting diode (LED) module 2 is provided with and is connected in series first illuminating part 21 and second illuminating part, 22, the first illuminating parts 21 that form with a plurality of light emitting diode and is connected in first load node 31, and second illuminating part 22 is connected in second load node 41.
When importing AC powers (as: 110V AC power) with second source node 42 through above-mentioned first power supply node 32; Make and win bridge rectifier 3 when work; There are two diode D1, D4 conducting and two diode D2, D3 to end simultaneously; Or two diode D2, D3 conducting and two diode D1, D4 end, and let the output voltage on first illuminating part 21 keep identical polarity, so so that 21 runnings of first illuminating part; And second bridge rectifier 4 is when work; There are two diode D5, D8 conducting and two diode D6, D7 to end simultaneously; Or two diode D6, D7 conducting and two diode D5, D8 end; Let the output voltage on second illuminating part 22 keep identical polarity, so so that 21 runnings of first illuminating part.
See also Fig. 3 to shown in Figure 5; When user's desire improves the voltage (as: 220V AC power) of first power supply node 32 and 42 input ac powers of second source node; The user connects first load node 31 earlier with second load node 41; So that first illuminating part 21 and second illuminating part 22 form series-like; This moment since first power supply node 32 and second source node 42 for being parallelly connected shape, and first load node 31 is connected with second load node 41, so diode D2, D4, D5, D7 between first power supply node 32 and the second source node 42 promptly can form short circuit (as shown in Figure 5); And when AC power is imported first power supply node 32 with second source node 42; Have two diode D1, D8 conducting and two diode D3, D6 to end simultaneously, or two diode D3, D6 conducting and two diode D1, D8 end, let first illuminating part 21 of flowing through keep identical polarity with the output voltage of second illuminating part 22; And then get so that first illuminating part 21 and 22 runnings of second illuminating part; And, therefore can not let first illuminating part 21 and second illuminating part 22 burn because of the voltage raising of input ac power because 22 one-tenth series-like of first illuminating part 21 and second illuminating part have improved voltage required when starting.
Therefore; The present invention is for solving the deficiency and the shortcoming of prior art; Its key technology is; The present invention utilizes first bridge rectifier 3 and second bridge rectifier 4 to be connected respectively by a plurality of light emitting diode and is connected in series first illuminating part 21 and second illuminating part 22 that forms, and utilizes first load node 31 whether to connect with second load node 41, required voltage when changing first illuminating part 21 and second illuminating part 22 and starting; To let the voltage starting of the light-emitting diode (LED) module 2 different AC powers capable of using on the same circuit substrate 1, make things convenient for the user to use.
