Lighting device
View Patent ↗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.
1. A lighting device comprising:
a battery housing configured to hold a battery;
a light housing configured to emit light from a light source; and
a switch coupled between the battery and the light source, wherein the light housing is movable towards the battery housing to form a closed circuit between the battery and the light source and the light housing is movable towards the battery housing to form an open circuit between the battery and the light source.
2. The lighting device of claim 1 , wherein the light source comprises a light emitting diode.
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 an amount of ambient light detected by the light detector.
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. 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 close the circuit and the light housing is movable towards the battery housing to open the circuit.
10. The lighting device of claim 9 , wherein the light source comprises a light emitting diode.
11. The lighting device of claim 9 , wherein the light source comprises a lamp.
12. The lighting device of claim 9 , wherein the light housing comprises a lens assembly.
13. The lighting device of claim 9 , wherein the circuit comprises a light detector that controls an intensity of the light source according to an amount of ambient light detected by the light detector.
14. The lighting device of claim 13 , wherein the light detector increases intensity of the light source as the ambient light increases.
15. The lighting device of claim 13 , wherein the light detector decreases intensity of the light source as the ambient light increases.
16. The lighting device of claim 1 , wherein the battery housing comprises a battery.
17. A circuit for use in a lighting device, the circuit comprising:
a power source;
a light source configured within a light housing to emit light out of the light housing;
a transformer coupled to the power source and the light source, wherein the transformer steps up voltage from the power source to a higher voltage power for the light source, and
a switch coupled to the power source and the light source, wherein the switch closes the circuit according to movement of the light housing toward the power source.
18. The circuit of claim 17 , wherein the power source has a voltage of about 1.5 volts and the higher voltage power has a voltage of about 3.6 volts.
19. The circuit of claim 17 , wherein the light source is a light emitting diode.
20. The circuit of claim 17 , further including a light dependent circuit coupled to the switch, wherein the light dependent circuit prevents current flow to the light source based on ambient light conditions.
21. The circuit of claim 20 , wherein the light dependent circuit includes a light dependent resistor.
