Abstract

An advertising light emitting pen comprises an upper pen tube and a lower pen tube. The feature of the advertising light emitting pen is that a top of the light guide tube resists against a lower end of the light emitting device. A surface of the inner tube is coated with film having advertising patterns or texts thereon. The film includes two parts with one part being a transparent surface and another part being an opaque surface for printing with pattern or texts. The transparent surface has no pattern or text thereon. When the light emitting device lights up, light transmits into the inner tube through the light guide tube and then emits out from the inner tube; the light emits from the outer tube to radiate into a paper to be written.
