LED device with voltage-limiting unit and voltage-equalizing resistance |
摘要 |
The present invention provides a LED device with voltage-limiting unit and voltage-equalizing resistance in which a light-emitting unit is structured through a LED being connected in parallel with a voltage-limiting unit in the same polarity, and two ends thereof being further connected in parallel with an voltage-equalizing resistance, so that when plural sets of the light-emitting units are connected in series or in series-parallel in the same polarity, the end voltage of each set is stabilized by the voltage-equalizing resistance connected in parallel with the two ends of the LED and the voltage-limiting unit. |

1. An LED device, comprising:
at least two light-emitting units, each said light-emitting unit including:
at least one light-emitting diode (101);a voltage-limiting unit (105) connected in parallel with the at least one light-emitting diode (101), the voltage-limiting unit (105) including a semiconductor unit having a resistance that rapidly drops when subject to overvoltage;a voltage-limiting resistance (107) connected in parallel with the at least one light-emitting diode (101), the voltage-limiting resistance (107) including a resistive component; wherein said at least two of the light-emitting units are connected in series or series-parallel with a respective said at least one light-emitting diode (101) in each of said at least two light-emitting units having a same polarity. |
