PROBLEM TO BE SOLVED: To make it possible for a person to do personal work easily in the dark. SOLUTION: An arc-formed headband 2 that can be set on a head in the state of being spanned over it by resiliently altering its form, has on its ear pad 4, at its end, an arm 5 that is moved freely upward and downward which is provided at its tip with an LED 10 (light-emitting diode) emitting white light. Inside the ear pad 4 is provided a rotary switch 9 that is connected to a cell and the LED 10. Pulling down the arm 5 will initiate lighting the area near the hands. |
