Abstract
A light emitting diode having a helical spring around one of its leads. The spring extends so that it has a free end which is cantilevered. As the free end of the spring moves it completes an electrical circuit intermittently lighting the light emitting diode.
Claims4
An assembly for providing intermittent light with movement comprising;
- a light emitting diode having first and second conductors extending therefrom;
- a conductive, flexible spring supported on said first conductor and in electrical contact therewith, said spring having a free end extending in a cantilevered manner past said first conductor to provide a movable spring portion;
- a conductive tube surrounding said moveable spring portion of said spring;
- and
- a battery having first and second terminals, said first terminal of said battery connected to said conductive tube and the second terminal of said battery connected to said second conductor of said light emitting diode.
