Abstract

A lighting device comprising, one or more semiconductor light-sources for generating a light beam, at least a motor for rotating said light beam, and a controller for controlling speed of rotation of the motor and intensity of the light-source and monitoring the operating conditions, detecting failures of the lighting device and/or, any of its components and setting off alarms which could be audio/visual and/or, radio or, telecom equipment using land and/or, air and/or, satellite links. The light beam generated by the light-sources is rotated. The light assembly broadly finds application in aviation industry, obstacle beacons, lighthouses and entertainment industry.

Claims

1. A lighting device comprising,

one or more semiconductor light-sources for generating a light beam,

at least a motor for rotating said light beam, and;

a controller for controlling speed of rotation of the motor and intensity of the light-source and monitoring the operating conditions.

2. A lighting device as claimed in claim 1, wherein said light beam is rotated using a reflector.

3. A lighting device as claimed in claim 1, wherein said light beam is rotated using a stationary light-source and rotating reflector or, stationary reflector and rotating light-source or, any combination thereof.

4. A lighting device as claimed in claim 1, wherein semiconductor light-source includes one or more lighting elements.

5. A lighting device as claimed in claim 4, wherein said lighting elements are LED(s) and/or, laser diodes and/or, quantum dots.

6. A lighting device as claimed in claim 5, wherein said lighting elements are provided with a focusing arrangement for focusing the light in a direction and are mounted on a mount.

7. A lighting device as claimed in claim 6, wherein mount includes metal plates for sinking heat.

8. A lighting device as claimed in claim 1, wherein said controller is controlling speed of rotation of the motor, intensity of the light-source(s), monitoring the operating conditions, detecting failures of the lighting device and/or, any of its components and setting off alarms which could be audio/visual and/or, radio or, telecom equipment using land and/or, air and/or, satellite links.

9. A lighting device as claimed in claim 1, wherein said controller is provided with options to program the controller from a remote location for controlling the motor and the light source.

10. A lighting device as claimed in claim 1, wherein the controller is coupled to the light-source through semi-conductor switch.

11. A lighting device as claimed in claim 1, wherein lighting device is powered by non-conventional or, conventional power supply.

12. A lighting device as claimed in claim 1, wherein said conventional power supply is an AC to DC and/or, DC to DC power supply.

13. A lighting device as claimed in claim 1, wherein said light source is switched ON using a light dependent sensor and/or, a timer.

14. A lighting device as claimed in claim 1, wherein said lighting device is water and dust proof and protected with lightening arrestors.
