screws. A battery is put in the shell for providing the light source module the electric
energy to illuminate. The positive electrode of the battery is conducted with the
positive electrode of the light source module, and a switch is set in the lateral
side of the shell, making the switch conducting with the negative electrode of the
battery. When the switch is pushed, the switch is contacted to the reflector lamp
cup of the lampshade base, which lampshade base is conducted to the negative electrode
of the light source module, making the electric energy be a loop. Therefore, the illuminating
function of the light source module is opened or closed via the control of the switch.
[0004] However, the foregoing flashlight can achieve the illuminating function by providing
the necessary electric energy to the light source module, but the following disadvantages
are discovered in actual use.

base is conducted to the negative electrode of the light source module to do power
transmission, so it is appeared that the assembly is very inconvenient, and the bad
connection or short circuit is occurred more easily, resulting that the light source
module cannot illuminate; furthermore, it is consumed more electric energy due to
the larger inner resistance of the reflector lamp cup.

base is conducted to the negative electrode of the light source module to do power
transmission, so the reflector lamp cup needs to be made of metal material, not only
making limit for the material choice and the performance of the reflector lamp cup,
but also the manufacture cost is increased.
