Abstract
A flash type optic pen comprises a pen body, a seat and a transparent telescopic head. The pen body is electrically connected to a battery and a switch. The seat is assembled to the front end of the pen body and has at least one circuit board and a plurality of light emitting diodes electrically connected to the circuit board. The transparent telescopic head is formed by a plurality of transparent staged tubes having reducing diameters. Thus, the pen body has the functions of writing and illumination. The light emitting angles, colors, heights and orientations of the light emitting diodes are different. The circuit board is installed with a programmable IC circuit for presetting and controlling the lighting up and extinguishing order of the light emitting diodes. The lights from the light emitting diodes are alternatively changed in a predetermined way or randomly, or flashes overlapped or separately. Viewing the optic pen from the outer side of the transparent telescopic head, it can see that lights of different colors change the positions continuously so as to present a vivid and beautiful visual effect.
