    Abstract: A device and a method for driving a light-emitting diode include using multiple current guiding control circuits to drive multiple LED modules. Each of the current guiding control circuits includes at least two transistors connected in parallel to constitute at least two switch circuits. Each of the current guiding control circuits permits or prevents electric current to flow to an immediate downstream one of the LED modules in response to a predetermined voltage level of the positive part of a voltage source. The respective the current guiding control circuits are responsive to different voltage levels. As a result, a maximum number of LED modules are driven to emit light at a given voltage level, thereby achieving the purposes of efficiently utilizing electric power and reducing power loss.

    Abstract: An electronic device includes a base, an intermediate member and a lens. The base includes a guiding portion, and a first, second and third connecting portions. The intermediate member includes a first, second and third engaging portions connected to the first, second and third connecting portions, respectively. The lens is disposed at a predetermined position via the intermediate member. When the first engaging portion situated in a first position is connected to the first connecting portion, the intermediate member has at least two degrees of freedom. When the intermediate member is positioned at a second position from the first position by the guide of the guiding portion, the second and third engaging portions are connected to the second and third connecting portions, wherein the intermediate member has zero degree of freedom, and the lens is disposed at the predetermined position via the intermediate member.
