LED light string with open circuit protection |
| 摘要 |
An LED light string with open circuit protection has a first end for receiving a first voltage, a second end for receiving a second voltage, and multiple LED units connected in series between the first end and the second end. Each of the LED units has multiple LEDs and at least one by-pass resistor connected in parallel. Even when the LEDs of the same LED unit all fail, a current from the first end to the second end can still flow through all the LED units via the by-pass resistors to drive the remaining normal LED units. |
