Abstract

A light source device which employs light energy transmitted through an optical conductor cable as a photo-synthesizing light source for cultivating plants. The light energy emitted from the optical conductor cable is effectively dispersed in order to nurture plants. The light source device is comprised of a hollow cylinder, a rotating support member for supporting the cylinder which rotates around a first axis perpendicular to the axis of the cylinder, a fixed supporting member for supporting the rotating support member which rotates around a second axis intersecting with the axis of the cylinder and another axis perpendicular to that of the cylinder, and a driving mechanism for rotating the cylinder around the first axis and the second axis at the edge portion of the cylinder, and an optical conductor cable inserted into the cylinder at a place near to the first axis, the edge portion surface of which is elongated to the other edge portion of the cylinder.

Claims

1. A light source device comprising a hollow cylinder, a support pin member for supporting said cylinder such that the cylinder can oscillate about a first axis perpendicular to a central axis of said cylinder, a pedestal member pivotably supporting said support pin member, a fixed supporting member for supporting said pedestal member such that the pedestal member can oscillate about a second axis intersecting with the central axis of said cylinder and intersecting said first axis, a driving mechanism for oscillating said cylinder around said first axis and said second axis at a first end of said cylinder, and an optical conductor cable inserted into said cylinder at a place near to said first axis, said cable extending within said cylinder from said place near to said first axis to an end portion of the cylinder opposite said first end.

2. A light source device as defined in claim 1, wherein said driving mechanism comprises a motor and a rotating arm which is rotated by said motor, said rotating arm having a first end with a connecting bar elongated therefrom in a direction substantially parallel to the central axis of the cylinder, and an edge portion of said connecting bar is rotatably connected with said cylinder therein at said first end of said cylinder.

3. A light source device as defined in claims 1 or 2, wherein said cylinder is provided with a moveable member at said first end of said cylinder, said moveable member being constructed so as to extend and retract relative to said cylinder.

4. A light source device as defined in claim 2, wherein a plurality of said connecting bars are provided in a radial direction of said rotating arm.

5. A light source device as defined in either one of claims 2 or 4, wherein said rotating arm has a balancing weight attached diametrically opposite said first end of said rotating arm.

6. A light source device as defined in claim 5, wherein said balancing weight is movable in the radial direction of said rotating arm.

7. A light source device comprising a hollow cylinder, a support pin member for supporting said cylinder such that the cylinder can oscillate about a first axis which is perpendicular to a central axis of said cylinder, a pedestal member pivotably supporting said support pin member, a fixed supporting member for supporting said pedestal member, such that said pedestal member can oscillate about a second axis intersecting with the central axis of said cylinder and with said first axis, a driving mechanism for oscillating said cylinder around said first axis and said second axis at a first end of said cylinder, a carrying table for carrying said fixed supporting member and said driving mechanism, a support mechanism for pivotably supporting said carrying table, and an optical conductor cable inserted into said cylinder at a place near to said first axis, said cable extending within said cylinder from said place near to said first axis to an end portion of the cylinder opposite said first end.

8. A light source device as defined in claim 7, wherein said supporting mechanism comprises a rotating support leg which is connected with said carrying table and a fixed supporting leg fixedly mounted on a foundation, both of said supporting legs being connected with each other through a flange portion, said flange portion having a plurality of bolt holes for connecting said rotating support leg and said fixed supporting leg with said flange portion, said rotating support leg being rotatable in relation to said fixed supporting leg by changing the relative position of said bolt holes to be connected.

9. A light source device as defined in claim 7, wherein said carrying table pivots around a horizontal axis.

10. A light source device as defined in claim 9, wherein the amount of pivoting of said carrying table is adjusted by the use of a motor.

11. A light source device as defined in claim 9, wherein said support mechanism comprises an arm for adjusting the amount of pivoting and a supporting leg, said arm having pin-receiving holes bored therein at intervals of a predetermined distance, said supporting leg having a pin-receiving hole said pin-receiving holes of said arm being employed for adjusting the pivoting of said carrying table in relation to said pin-receiving hole of said support leg.

12. A light source device as defined in claim 11, wherein said supporting leg is constructed so as to rotate around a vertical axis.
