Abstract
The present invention relates to a portable apparatus including a fastening mechanism for use with the light-emitting disk. The clamping area of the light-emitting disk has a plurality of conductive terminals, and the touch portion of the fastening mechanism connected with the conductive terminals can supply electrical power to light up the light-emitting disk. Furthermore, the light-emitting disk can light partially, intermittently or colorfully by itself because the fastening mechanism controls the electrical power in different modes.
