Abstract
An LED power transmission line with load identification function is coupled to an LED power control apparatus having a plurality of power output ports and an LED load. The LED power transmission line includes a power transmission circuit, a signal transmission circuit, and a memory apparatus. The power transmission circuit transmits a power outputted from the power output port to the LED load. The signal transmission circuit is coupled to a control module of the LED power apparatus through the power output port. The memory apparatus stores an LED specification information related to an electrical specification of the LED load. The LED specification information is provided to the control module through the signal transmission circuit so that the control module limits an output current outputted from the power output port according to the LED specification information.
