Abstract

Provided is a power supply device, provided for a light source device which has a plurality of light-emitting bodies. The power supply device includes a circuit for controlling a current supplied to the light-emitting body. The power supply device also includes a control circuit for controlling a current from a power supply source, the control circuit being disposed at the central portion of the light source device. The power supply device additionally includes a cooling component capable of cooling surroundings by channeling a refrigerant, where the cooling component is provided on a back side of the light-emitting body. The power supply device also includes a heat transfer component connecting the cooling component and the control circuit to each other. The power supply device further includes an insulating component interposed between the heat transfer component and the control circuit at a state in contact with both.

First claim

The invention claimed is:

1. A power supply device, provided for a light source device which has a plurality of light-emitting bodies on each of which a large number of light emitting diodes are mounted, an entirety of the plurality of light-emitting bodies being covered with a cylindrical light transmitting container, said power supply device comprising:
a circuit for controlling a current supplied to the entirety of the plurality of light-emitting bodies;
a control circuit for controlling a current from a power supply source, said control circuit being disposed at a central portion of said light source device;
a cooling means capable of cooling surroundings by channeling a refrigerant, said cooling means being provided on a back side of the entirety of the plurality of the light-emitting bodies;
a heat transfer means connecting said cooling means and said control circuit to each other; and
an insulating means interposed between said heat transfer means and said control circuit at a state in contact with both,

wherein
the control circuit is positioned inside the power supply device and surrounded with the plurality of the light-emitting bodies, and
the cooling means cools the control circuit via the heat transfer means and at a same time cools the entirety of the plurality of light-emitting bodies.

2. The power supply device according to claim 1 , wherein said control circuit comprises a circuit component comprising at least a switching element or/and a reactor, and at least said insulating means is in contact with said circuit component.

3. The power supply device according to claim 1 , wherein said cooling means comprises means having a cooling water channeling passage.

4. The power supply device according to claim 1 , wherein said heat transfer means comprises a metal member having a thermal conductivity coefficient of 2 W/m·K or more.

5. The power supply device according to claim 1 , wherein said insulating means comprises a sheet-like member having a thermal conductivity coefficient of 0.4 W/m·K or more.

6. The power supply device according to claim 1 , further comprising an urging means capable of urging said heat transfer means to the side of said control circuit.

7. The power supply device according to claim 6 , further comprising an urging force adjustment means for adjusting an urging force of said urging means.

8. The power supply device according to claim 7 , wherein said urging force adjustment means comprises a spring member.

9. The power supply device according to claim 1 , wherein said light-emitting body is one irradiated light of which is used for a photochemical reaction.

10. A photochemical reaction device comprising a photoirradiation device having a light emitting diode group connected to the power supply device according to claim 1 .

11. A photochemical reaction method characterized by using the photochemical reaction device according to claim 10 .

12. The photochemical reaction method according to claim 11 , wherein a destination of photoirradiation is a liquid, and the composition of said liquid contains at least a carbon atom.

13. The photochemical reaction method according to claim 12 , wherein said liquid as the destination of photoirradiation is a cycloalkane.

14. The photochemical reaction method according to claim 13 , wherein said cycloalkane is cyclohexane or cyclododecane.

15. The photochemical reaction method according to claim 13 , wherein a cycloalkanone oxime is produced by performing photoirradiation to said cycloalkane and a photo nitrosating agent.

16. The photochemical reaction method of claim 15 , wherein said photo nitrosating agent is nitrosyl chloride or trichloronitrosomethane.

17. A method for producing a lactam characterized by converting cycloalkanone oxime produced by the photochemical reaction method according to claim 16 to lactam.

18. The power supply device according to claim 1 , wherein said heat transfer means comprises a heat transfer member having a L-shaped cross section.
