Abstract

A high power LED Housing consisting of one or more LED to form a LED assembly fitted into a metal body having an upper portion with a gripping means and a lower portion with a fitting means and a base. The LED assembly is connected by electrical wire to a base of the metal body, the base of the metal body having an electrical contact.

By means of the gripping means, the LED housing can be installed or removed from a socket shaped to receive the LED housing.

The LED housing can be assembled into panels of LED housing which can be fitted with electrical and electronic circuits to monitor and control the operation of the LED housing for various applications.

Claims

1. A high power light emitting diode (LED) Housing comprising:

one or more LED forming a LED assembly;

a metal body;

said metal body having a top, an upper portion having gripping means, a lower portion and a base;

said LED assembly mounted within the said metal body, and a lens fitted onto said top of said metal body, said lower portion having fitting means on the exterior;

said LED assembly connected by electrical wire to an electrical contact in said metal body;

wherein said LED housing is adapted to be installed on a metal plate acting as a heat sink having a socket by fitting said LED housing into said socket in said heat sink, said socket shaped to receive said lower portion of said LED housing and said LED housing being removable from said heat sink by unfitting said LED housing from said socket.

2. A high power LED housing as claimed in claim 1 wherein said LED housing is fitted into said heat sink with said gripping means by turning or twisting said LED housing into said shaped socket and said LED housing is unfitted from said heat sink with said gripping means by turning or twisting said LED housing from said shaped socket.

3. A high power LED housing as claimed in claim 1 wherein said lens has a lens base, and wherein said LED assembly is mounted on a slug, said LED assembly and slug are mounted on said lens base with epoxy resin.

4. A high power LED housing as claimed in claim 1 wherein said LED assembly is a die mounted on said lens base with die resin.

5. A high power LED housing as claimed in claim 1 wherein said LED assembly is a Red color LED, a Green color LED or a Blue Color LED.

6. A high power LED housing as claimed in claim 1 wherein said LED assembly is a Red color LED and a Green color LED, a Red color LED and a Blue Color LED, or a Green color LED and a Blue Color LED.

7. A high power LED housing as claimed in claim 1 wherein said LED assembly is a Red color LED, a Green color LED and a Red color LED.

8. The metal body for a high power LED housing as claimed in claim 1 wherein said metal body has said upper portion having a plurality of sides formed as said gripping means and said lower portion in the form of a T shaped bolt.

9. The metal body for a high power LED housing as claimed in claim 1 wherein said metal body is cylindrically shaped with a round cross section, said metal body having said upper portion adapted as said gripping means.

10. The metal body for a high power LED housing as claimed in claim 1 wherein said metal body is in the form of a button mushroom with a wider mushroom shaped top and a narrow lower portion, said wider mushroom shaped top adapted as gripping means.

11. The metal body for a high power LED housing as claimed in claim 1 wherein said fitting means comprises circular screw threads.

12. The metal body for a high power LED housing as claimed in claim 1 wherein said fitting means comprises a snap.

13. A high power LED housing as claimed in claim 1 wherein said electrical contact includes a circuit board and when fitted into said shaped socket in said heat sink, is further connected thereto to a electrical power source to light up the LED assembly.

14. A high power LED housing as claimed in claim 1 wherein said electrical contact is located at the base of said metal body.

15. A high power LED housing as claimed in claim 1 wherein said electrical contact is located at the undersurface of the upper portion of said metal body.

16. A high power LED housing as claimed in claim 1 wherein said electrical contact is located at the side of the upper portion of said metal body.

17. A circuit board for a high power LED housing as claimed in claim 1 wherein said circuit board comprises a voltage regulator, current control circuit and monitoring and feedback circuit.

18. A circuit board for a high power LED housing as claimed in claim 1 wherein said circuit board comprises a voltage regulator, current control circuit and monitoring and feedback circuit and temperature sensor.

19. A LED housing as claimed in claim 1 wherein the base of said metal body has a single or multiple spring loaded electrical contact assembly, for contact with the electrical circuit.

20. A LED light source comprising a plurality of LED housings as claimed in claim 1 said plurality of LED housings arranged in a linear pattern to form a LED panel, said plurality of LED housings being connected to an electrical circuit comprising a voltage regulator, current control circuit, a monitoring and feedback circuit, power regulator and light sensor control unit so that feedback on the performance of the LED are transmitted to a control center so that electronic signals are in turn transmitted to said LED housings so that said LED light source is controlled to give colored patterns of LED lights to form an electronic image in the form of an advertisement.

21. A LED light source comprising a plurality of LED housings as claimed in claim 20 arranged in a linear pattern on a reflector to form a panel of LED.

22. A LED light source as claimed in claim 20 arranged in a linear pattern on a curved concave reflector to form one or more wide angled LED arrays and one or more narrow angle LED arrays.

23. A LED light source as claimed in claim 20 arranged in a linear pattern on a curved convex reflector to form one or more wide angled LED arrays and one or more narrow angle LED arrays.

24. A LED light source as claimed in claim 20 arranged in a linear pattern on a flat reflector comprising one or more wide angled LED arrays and one or more narrow angle LED arrays.

25. A LED light source as claimed in claim 20 arranged in a linear pattern on a reflector, so that sufficient numbers of LED are turned on in said LED light source to suit the light conditions as determined by said light sensor control unit.

26. A LED light source as claimed in any one of claim 20 to claim 24 having an ultra-violet (UV) cover for the LED panels wherein said UV cover acts as an UV light filter to prevent excess UV light from leaking into the surroundings.
