The present invention relates to a light emitting device using a direct current power. More particularly, the light emitting device using direct current power comprises: a direct current operating part which continuously outputs a direct current power of a preset level; a plurality of light emitting elements which output light having different ranges of wavelengths; a switching part which turns the light emitting element on and off at individual power lines connecting the direct current operating part with the plurality of light emitting elements; and a control part which turns the switching part on and off at preset times to control the light of the light emitting elements. The light emitting device using direct current power does not need a separate circuit preventing negative oscillation, and has a compact size and light weight in comparison to a conventional device, thereby being easy to be carried around. Also, the light emitting device has reduced number of components used, and thus has inexpensive manufacturing costs. |
