Abstract
A toy flashlight formed in a configuration including a strobe module. The flashlight includes a handle housing and a releasably mounted transparent enclosure with the strobe module enclosed therebetween. The strobe module is provided to switch a light source between ON state and an OFF state to create a rapidly blinking light. Further, a strobing circuit is provided to control the switching mechanism of the strobe module. In this manner, the strobe module with strobing circuit can be inserted into a conventional flashlight to enhance its play value.
Claims17
An amusement device comprising handle means for receiving a power supply therein, light source means releasably mounted to said handle means for emitting a beam of light, strobe means mounted to said handle means for controlling the output of said beam of light, said strobe means including a Darlington circuit having a first transistor and a second transistor, said first transistor having an emitter and a base, said second transistor having an emitter and a collector, said emitter of said first transistor and said collector of said second transistor coupled to said light source;
- an RC circuit coupled to said base of said first transistor and to said collector of said second transistor;
- a drain resistor coupled to said RC circuit, said base of said first transistor and said emitter of said second transistor and said power supply coupled to said emitter of said first transistor and said light source, said handle means including a switching means connected to said light source means, said power supply and said strobe means for supplying power to said strobe means and a substantially transparent enclosure means releasably mounted to said handle means so that said beam of light transmits through said transparent enclosure;
- wherein said strobe means turns said light source means to an on state and an off state so that said beam of light blinks.
A strobing circuit for switching a light source between an on state and an off state, comprising:
- a Darlington circuit having a first transistor and a second transistor, said first transistor having an emitter and a base, said second transistor having an emitter and a collector, said emitter of said first transistor and said collector of said second transistor coupled to said light source;
- an RC circuit coupled to said base of said first transistor and to said collector of said second transistor;
- a drain resistor coupled to said RC circuit, said base of said first transistor and said emitter of said second transistor;
- and
- power supply means coupled to said emitter of said first transistor and said light source for driving said strobing circuit.
A strobing circuit for rapidly switching a light source between an on state and an off state, comprising:
- power supply means for supplying charge to the circuit;
- charging means for storing the charge received from the power supply means for a predetermined period of time;
- and
- switching means for switching between the on state and the off state based on the charge of the charging means;
- said switching means including a first transistor and a second transistor, said first transistor having an emitter and a base, said second transistor having an emitter and a collector, said emitter of said first transistor and said collector of said second transistor coupled to said light source;
- said charging means coupled to said base of said first transistor and said collector of said second transistor, the switching means being in the on state when the charge is stored in the charging means;
- the switching means being in the off state when no charge is stored in the charging means;
- the light source being in the on state for the predetermined period of time of the charging means when the switching means is in the on state and the light source is in the off state when the switching means is in the off state.
