Abstract

A miniature LED flashlight is provided having a battery with opposing surfaces of opposite polarity and an LED having two leads extending therefrom, the battery and the LED received within a molded lower panel. A adapted to press fit with the lower panel in simultaneous contact with the frame creates a flashlight that is readily opened to interchange and replace component parts. The upper panel also has an upper surface, a side and an aperture extending through the upper surface. The side of the upper surface has a notch receive a lever for detaching the upper panel. Transverse finger pressure on the aperture urges the LED leads into contact with the opposing surfaces of the battery thereby illuminating the LED. A dual mode switch is also provided to slide within the aperture. The resulting flashlight may exist as a self-contained variety of outer housing structures.

Claims

1. A flashlight comprising:

a battery having opposing surfaces of opposite polarity;

a light emitting diode having a first lead and a second lead extending therefrom, the leads adapted to engage the opposing surfaces of the battery;

a lower panel adapted to receive said battery and said LED;

a frame attached to said lower panel;

an upper panel having an upper surface, a side and an aperture extending through the upper surface; and

snap fittings adapted to press fit with said lower panel in simultaneous contact with said frame.

2. The flashlight of claim 1 wherein said upper panel has a notch in the side such that a wall of the notch is defined by said frame and the notch is adapted to receive a lever for detaching said upper panel from said lower panel.

3. The flashlight of claim 1 further comprising a dual function switch adapted to insert between said upper panel and the second lead so that lateral movement of said switch urges the second lead into a condition selected from the group consisting of:

constant contact between the leads and the opposing surfaces of said battery, and intermittent contact between the leads and the opposing surfaces of the battery induced by a further transverse pressure exerted on said switch.

4. The flashlight of claim 1 wherein the first lead is in constant contact with a battery pole and said second lead contacts the opposing battery pole through a bridging connector.

5. The flashlight of claim 4 wherein the bridging connector is a leaf spring.

6. The flashlight of claim 1 wherein said frame is metal.

7. The flashlight of claim 6 wherein said frame is pot metal.

8. The flashlight of claim 1 wherein said frame is configured to form a hook.

9. The flashlight of claim 7 further comprising a spring clip urged into contact with the hook.

10. The flashlight of claim 1 wherein the dual function switch has a rocking undercarriage adapted to urge a leaf spring into simultaneous contact with the second lead and the opposing battery pole.

11. The flashlight of claim 1 wherein said battery is a lithium disc battery.

12. The flashlight of claim 1 wherein said LED is a gallium nitride LED.

13. The flashlight of claim 1 wherein at least one of said upper panel and said lower panel is translucent.

14. The flashlight of claim 1 wherein said upper panel and said lower panel are formed of thermoplastic material.

15. The flashlight of claim 1 wherein said frame is metal plated.

16. A flashlight comprising:

a button battery having a battery pole and a second surface of opposite polarity;

a light emitting diode having a first lead and a second lead extending therefrom, the first lead in constant contact with the battery pole;

a lower panel adapted to receive said battery and said LED;

a metal frame attached to said lower panel, wherein a portion of said frame is configured as a hook;

a spring affixed to said frame being urged into contact with the hook;

an upper panel having an upper surface, a side having a notch such that a wall of the notch is defined by said frame, an aperture extending through the upper surface; and

snap fittings adapted to press fit with said lower panel in simultaneous contact with said frame.

17. The flashlight of claim 16 further comprising a dual function switch adapted to insert between said upper panel and the second lead so that lateral movement of said switch urges a leaf spring into simultaneous contact between the second lead and the second surface of opposite polarity to induce a condition selected from the group consisting of:

constant contact with the second surface of opposite polarity, and intermittent contact between the second lead and the second surface of opposite polarity induced by a further transverse pressure exerted on said switch.

18. The flashlight of claim 16 wherein said frame is pot metal.

19. The flashlight of claim 16 wherein said battery is a lithium disc battery.

20. The flashlight of claim 16 wherein said LED is a gallium nitride LED.

21. The flashlight of claim 16 wherein said upper panel and said lower panel are formed of thermoplastic material.

22. The flashlight of claim 16 wherein said frame is metal plated.
