An LED string with a capability to maintain a current path has multiple LED units electrically connected in series. Each of the LED units has a base, a holder, a bridge device, a cover and an LED device. The base has two conductive pads. The holder and the cover are mounted in the base. The bridge device is mounted in the holder. The LED device is mounted in the cover. The bridge device and the LED device are electrically connected in parallel and contact the conductive pads. When the LED device is damaged, the bridge device still contacts the conductive pads. Hence, the bridge device provides a path that allows a current to flow through the conductive pads. |
