Abstract

The present invention provides a lighting device having a battery housing to hold a battery, a light housing having a light source and a lens assembly into which said light source will emit light when activated, said battery and said light source being in circuit with a switch to open and close said circuit, said light housing being moveable relative to said battery housing to motivate said switch to open and/or close said circuit.

Claims (45)

1. A lighting device comprising:

a battery housing;

a light housing having a light source that emits light when activated;

a circuit comprising a switch, the circuit coupled to the battery housing and the light source; and

wherein the light housing is movable towards the battery housing to motivate the switch to close the circuit and the light housing is movable towards the battery housing to motivate the switch to open the circuit.

2. The lighting device of claim 1 , wherein the light source comprises an LED.

3. The lighting device of claim 1 , wherein the light source comprises a lamp.

4. The lighting device of claim 1 , wherein the light housing comprises a lens assembly.

5. The lighting device of claim 4 , wherein the lens assembly comprises a translucent material having a frosted finish.

6. The lighting device of claim 1 , wherein the circuit comprises a light detector that controls an intensity of the light source according to ambient light.

7. The lighting device of claim 6 , wherein the light detector increases intensity of the light source as the ambient light increases.

8. The lighting device of claim 6 , wherein the light detector decreases intensity of the light source as the ambient light increases.

9. The lighting device of claim 1 , wherein the battery housing comprises a battery.

10. A lighting device comprising:

a battery housing;

a light housing comprising a light source that emits light when activated;

a circuit comprising a light detector, the circuit coupled to the light source; and

wherein the light detector controls an intensity of the light source according to ambient light; and

wherein the circuit further comprises a switch and wherein the light housing is movable towards the battery housing to motivate the switch to close the circuit and the light housing is movable towards the battery housing to motivate the switch to open the circuit.

11. A lighting device comprising:

a battery housing;

a light housing comprising a light source that emits light when activated;

a circuit comprising a light detector, the circuit coupled to the light source; and

wherein the light detector controls an intensity of the light source according to ambient light; and

a base coupled to the battery housing wherein the base includes a recess to receive a mounting spike.

12. A lighting device comprising:

a battery housing;

a light housing comprising a light source that emits light when activated;

a circuit comprising a light detector, the circuit coupled to the light source; and

wherein the light detector controls an intensity of the light source according to ambient light; and

wherein the light housing further comprises a firstreflector and the second reflector, wherein the first reflector is postioned near the light source and the second reflector is positioned away from the light source.

13. The lighting device of claim 12 , wherein the light detector increases intensity of the light source as the ambient light increases.

14. The lighting device of claim 12 , wherein the light detector decreases intensity of the light source as the ambient light increases.

15. The lighting device of claim 12 , further comprising a base coupled to the battery housing.

16. The lighting device of claim 15 , further comprising a foot mounted to the base.

17. A lighting device circuit comprising:

a power source;

a transformer connected to the power source;

a light source;

a transistor circuit connected to the transformer and the light source;

light dependent circuit connected to the transistor circuit and controllably turns the transistor circuit and the light source on and off; and

a switch connected to the transistor circuit to activate and deactivate the lighting device circuit according to movement of the light source toward the power source.

18. The lighting device circuit of claim 17 , wherein the light dependent circuit comprises a resistor and a light dependent resistor connected in series.

19. The lighting device circuit of claim 17 , wherein the light source is a white LED.

20. The lighting device circuit of claim 17 , wherein the power source is a battery and the transformer steps up voltage from the battery to illuminate the light source.
