According to the present invention, a portable light emitting device allows light emitted from a light emitting diode to pass through an aspheric cross-section lens array to improve linearity of light as well as visibility at a long distance. The device includes a light source unit which includes one or more light emitting diodes for emitting light; a lens array unit in which a first, a second, a third, and a fourth convex lens are arrayed to collect light emitted from the light source unit; a power unit which supplies power to the light source unit; and a housing unit which prevents separation of the light source unit, the lens array unit, and the power unit and provides a path for light emitted from the light source unit. |
