摘要:
A leveling method for burying an evaporating section of a heat pipe into a thermally conductive seat is provided for an assembly of heat pipe and heat-conducting seat by simultaneously making the evaporating section of heat pipe partially formed into a flat surface when the evaporating section of heat pipe is being burying into the thermally conductive seat. Furthermore, in cooperation with a stamping machine, the leveling method is to make a multiple steps of press-fitting process to an evaporating section of heat pipe under a condition that there is no need to change the stamping die.

A LED lamp tube which includes a hollow transparent tube, a LED lamp assembly disposed in the transparent tube, two conductive caps provided on both ends of the transparent tube respectively, and a circuit control unit. The circuit control unit includes a plurality of separated sub-portions. The respective sub-portions of the circuit control unit are distributed uniformly on the circuit board of the LED lamp assembly. Via the uniform arrangement of respective sub-portions of the circuit control unit, the heat within the LED lamp tube can be distributed uniformly, thereby lowering the temperature and facilitating the heat dissipation.

A multi-stage folding portable solar charging apparatus includes first, second and third photoelectric conversion modules. The second photoelectric conversion module is pivotally connected to a side of the first photoelectric conversion module and folded/unfolded with respect to an upper surface of the first photoelectric conversion module, and the third photoelectric conversion module is pivotally connected to another side of the first photoelectric conversion module and can be folded/unfolded with respect to a lower surface of the first photoelectric conversion module, such that the photoelectric conversion modules are electrically connected with each other. A connector is fixed and electrically connected to one of the photoelectric conversion modules. The second and third photoelectric conversion modules are unfolded from the stacked first photoelectric conversion module to increase an electric power generation area of charging apparatus when unfolded to enhance the electric power generation, and reduce the volume of the charging apparatus when folded.
