Abstract

Disclosed is a portable signal light. The portable signal light comprises a signal light section and a self-generator. The signal light section has a hollow signal light body to an inner surface of which a light emitting sheet is attached, a vertically positioned panel which is located inside the hollow signal light body, a plurality of LED elements which are fastened to the vertically positioned panel to be spaced apart one from another by a predetermined distance, and an illuminating lamp which is integrally secured to the hollow signal light body. The self-generator functions to generate power to be fed as operating power to the LED elements of the signal light section, the illuminating lamp and an external load.

Claims

1. A portable signal light comprising:

a signal light section having a hollow signal light body to an inner surface of which a light emitting sheet is attached, a vertically positioned panel which is located inside the hollow signal light body, a plurality of LED elements which are fastened to the vertically positioned panel to be spaced apart one from another by a predetermined distance, and an illuminating lamp which is integrally secured to the hollow signal light body; and

a self-generator for generating power to be fed as operating power to the LED elements of the signal light section, the illuminating lamp and an external load.

2. The portable signal light as claimed in claim 1, wherein a generator body of the self-generator is integrally coupled to the hollow signal light body of the signal light section.

3. The portable signal light as claimed in claim 1, wherein a generator body of the self-generator is detachably coupled to the hollow signal light body of the signal light section.

4. The portable signal light as claimed claim 1, wherein the self-generator comprises an operating lever one end of which is pivotably coupled to the generator body and which has integrally formed therewith a transmitting lever for transmitting external force, a plurality of gears which are rotated in response to the external force transmitted by the medium of the transmitting lever, a generator module which is rotated by stepwise speed-varied rotation of the plurality of gears to generate power, a reverse rotation-preventing gear which has a reverse rotation-preventing structure for preventing reverse rotation force from being applied to the generator module while external force is removed from the operating lever, intermediate gears for transmitting to a shaft gear of the generator module rotation force received from the reverse rotation-preventing gear, a feeding port for externally feeding a voltage generated in the generator module, and a battery pack which is detachably assembled to the generator body to receive power through the feeding port and thereby be charged with the power.

5. The portable signal light as claimed in claim 4, wherein a magnet member which has inclinedly magnetized N and S poles is installed on an inner wall surface of a rotor of the generator module.

6. The portable signal light as claimed in claims 4 or 5, wherein a weight for increasing inertial rotation force is added to the rotor of the generator module.

7. A portable signal light comprising:

a signal light section having a signal light body to an inner surface of which a light emitting sheet is attached, a vertically positioned panel which is located inside the signal light body, first and second columns of LED elements which are fastened to the vertically positioned panel to emit light of different colors from each other, and an illuminating lamp which is integrally secured to an outer surface of the signal light body; and

a self-generator connected to the signal light body for generating power to be fed as operating power to the first and second columns of LED elements and the illuminating lamp.

8. The portable signal light as claimed in claim 7, wherein the first column of LED elements are a red color emitting type and the second column of LED elements are a green color emitting type;

and a power switch is provided to the signal light body for selective driving of the first or second column of LED elements and driving of the illuminating lamp.

9. The portable signal light as claimed in claims 7 or 8, wherein the light emitting sheet has a green color.

10. The portable signal light as claimed in claim 7, wherein a generator body of the self-generator is integrally coupled to a lower end of the signal light body.

11. The portable signal light as claimed in claim 7, wherein a generator body of the self-generator is detachably coupled to a lower end of the signal light body.

12. The portable signal light as claimed in claim 7, wherein the self-generator comprises an operating lever one end of which is pivotably coupled to the generator body and which has integrally formed therewith a transmitting lever for transmitting external force, a plurality of gears which are rotated in response to the external force transmitted by the medium of the transmitting lever, a generator module which is rotated by stepwise speed-varied rotation of the plurality of gears to generate power, a reverse rotation-preventing gear which has a reverse rotation-preventing structure for preventing reverse rotation force from being applied to the generator module while external force is removed from the operating lever, intermediate gears for transmitting to a shaft gear of the generator module rotation force received from the reverse rotation-preventing gear, a feeding port for externally feeding a voltage generated in the generator module, and a battery pack which is detachably assembled to the generator body to receive power through the feeding port and thereby be charged with the power.

13. The portable signal light as claimed in claim 12, wherein a magnet member which has inclinedly magnetized N and S poles is installed on an inner wall surface of a rotor of the generator module.

14. The portable signal light as claimed in claims 12 or 13, wherein a weight for increasing inertial rotation force is added to the rotor of the generator module.
