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.

Abstract: A structure of a reversing actuating module of reciprocating pneumatic tools adopts an adaptation between the stage-shaped reversing block and the stage-shaped receiving groove. The bottom end of the air inlet flow path configured in the center of the air pressure inlet seat is not connected to the stage-shaped receiving groove through a straight hole, but a twisted hole formed through the inclined hole configured in the air pressure inlet seat to connect the air inlet flow path alternatively. Further, the diameter of the lower end of the inclined hole is partially enlarged so that the auxiliary ventilating part is corresponded to the area of expanding groove of the stage-shaped receiving groove. The structure can omit the configuration of a spacing ring component, while maintaining the function of reversing actuation. Therefore, the present invention can help to reduce production and processing cost, assembly time, and defect rate.
