A light source includes a light head and a heat transfer arrangement. The light head includes a tubular supporting frame, which has an interior space, and a luminary unit provided on the supporting frame. The heat transfer arrangement, for dissipating heat generated from the light head, includes a heat sink and a heat conductor having a sealed chamber, which has a first portion in the supporting frame and a second portion extended to the heat sink, and a cooling agent contained in the sealed chamber of the heat conductor, wherein the cooling agent is capable of being vaporized by the heat of the luminary unit and condensed by said heat sink so as to substantially enable the heat to flow from the luminary unit towards the heat sink.

What is claimed is: 1. A light source, comprising: a heat transfer arrangement, which comprises a tubular heat conductor having a sealed chamber and a peripheral surface, a heat sink thermally communicating with said heat conductor and a liquid cooling agent contained in said sealed chamber of said heat conductor; and a light head which comprises a circuit provided on said peripheral surface of said heat conductor and one or more diodes provided on said peripheral surface of said heat conductor to electrically connect with said circuit for emitting light in an outwardly radial direction of said light head, wherein said heat transfer arrangement is adapted for dissipating heat generated from said light head that said cooling agent is capable of transferring said heat away from said diode to said heat sink so as to maintain a predetermined temperature of said light head during operation. 2. The light source, as recited in claim 1, further comprising an electric adapter coupled with said light head and electrically connected to said luminary unit for connection with a conventional light bulb connector for electrically connecting with said power source via said light bulb connector. 3. The light source, as recited in claim 1, wherein said light head further comprises a transparent light shelter sealedly mounted on said peripheral surface of said heat conductor to sealedly enclose said circuit and said diode on said heat conductor. 4. The light source, as recited in claim 2, wherein said light head further comprises a transparent light shelter sealedly mounted on said peripheral surface of said heat conductor to sealedly enclose said circuit and said diode on said heat conductor. 5. The light source, as recited in claim 1, wherein said heat conductor further has a plurality of conduction channels spacedly provided on a surrounding wall of said sealed chamber, wherein said conduction channels are extended from said light head to said heat sink. 6. The light source, as recited in claim 2, wherein said heat conductor further has a plurality of conduction channels spacedly provided on a surrounding wall of said sealed chamber, wherein said conduction channels are extended from said light head to said heat sink. 7. The light source, as recited in claim 4, wherein said heat conductor further has a plurality of conduction channels spacedly provided on a surrounding wall of said sealed chamber, wherein said conduction channels are extended from said light head to said heat sink. 8. The light source, as recited in claim 1, wherein said cooling agent is being vaporized by said heat generated from said diode and condensed by said heat sink so as to enable said heat to flow from said diode towards said heat sink. 9. The light source, as recited in claim 4, wherein said cooling agent is being vaporized by said heat generated from said diode and condensed by said heat sink so as to enable said heat to flow from said diode towards said heat sink. 10. The light source, as recited in claim 7, wherein said cooling agent is being vaporized by said heat generated from said diode and condensed by said heat sink so as to enable said heat to flow from said diode towards said heat sink. 11. The light source, as recited in claim 8, wherein said cooling agent has a vaporization temperature lower than 100째 C. and higher than a room temperature. 12. The light source, as recited in claim 9, wherein said cooling agent has a vaporization temperature lower than 100째 C. and higher than a room temperature. 13. The light source, as recited in claim 10, wherein said cooling agent has a vaporization temperature lower than 100째 C. and higher than a room temperature. 14. The lighter, source, as recited in claim 4, wherein said heat sink is positioned above of said light head. 15. The lighter, source, as recited in claim 7, wherein said heat sink is positioned above of said light head. 16. The lighter, source, as recited in claim 13, wherein said heat sink is positioned above of said light head. 17. A light source, comprising: a heat transfer arrangement which comprises a heat sink, a tubular heat conductor having a sealed chamber which has one or more first portions and a second portion extended to said heat sink, and a cooling agent contained in said sealed chamber of said heat conductor; and one or more light heads provided at said first portion of said heat conductor for illumination, wherein said light head comprises a circuit provided on a peripheral surface of said first portion of said heat conductor and one or more diodes provided on said peripheral surface of said first portion of said heat conductor to electrically connect with said circuit for emitting light in an outwardly radial direction of said light head, wherein said heat transfer arrangement is adapted for dissipating heat generated from said light head that said cooling agent is capable of transferring said heat away from said diode to said heat sink so as to maintain a predetermined temperature of said light head during operation. 18. The light source, as recited in claim 17, wherein said light head further comprises a transparent light shelter sealedly mounted on said peripheral surface of said heat conductor to sealedly enclose said circuit and said diode on said heat conductor. 19. The light source, as recited in claim 18, wherein said cooling agent is being vaporized by said heat generated from said diode and condensed by said heat sink so as to enable said heat to flow from said diode towards said heat sink. 20. The light source, as recited in claim 19, wherein said cooling agent has a vaporization temperature lower than 100째 C. and higher than a room temperature.
