A portable reading light device utilizing an LEDs as the source of light mounted in a housing having a single lens through which light from the LEDs is projected, the power to the LEDs being controlled by Pulse Width Modulation. The cutting set is mounted on the top end of the support rod and has a fixed blade, a moving blade and a driving lever. In a first mode, the first switch and the second switch are turned off to split each coil element into a first upper coil portion and a second lower coil portion, to transmit first radio frequency signals. Next, a second silicon film is formed over the entire surface of the substrate so as to cover the gate interconnections. The first output signal sets the latching device with an edge of the first output signal of the first converter and resets the latching device with an edge of the second output signal of the second converter.
