Abstract
Abstract An ornamental lighting device includes a plurality of optical fibers to which condensed light from a light source is distributed through a fiber optic cable. The optical fibers are arranged parallel to each other and held between a pair of light transmitting panels, which are rigidly mounted on a pedestal. Light propagating through the optical fibers is radiated through the light transmitting panels to the ambience. A plurality of such lighting devices may be arranged side by side and supplied by a common light source.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
92 words
An ornamental lighting device for radiating condensed light which propagates through a fiber optic cable, comprising: a pedestal; a plurality of optical fibers supported by said pedestal and optically coupled with the fiber optic cable to be supplied with the condensed light; retainer means for retaining said optical fibers substantially parallel to each other and at a predetermining spacing from each other; and a pair of light transmitting panels mounted on the pedestal and mounting said retainer means to hold the parallel optical fibers in sandwich array between said light transmitting panels.
Claim 2
Dependent Claim
92 words
An ornamental lighting device for radiating condensed light which propagates through a fiber optic cable, comprising: a pedestal; a plurality of optical fibers supported by said pedestal and optically coupled with the fiber optic cable to be supplied with the condensed light; retainer means for retaining said optical fibers substantially parallel to each other and at a predetermining spacing from each other; and a pair of light transmitting panels mounted on the pedestal and mounting said retainer means to hold the parallel optical fibers in sandwich array between said light transmitting panels.
Claim 3
Dependent Claim
33 words
An ornamental lighting device as claimed in claim 1, in which the pedestal is formed with a duct therein, the fiber optic cable being optically coupled with the optical fibers through said duct.
Claim 4
Dependent Claim
34 words
An ornamental lighting device as claimed in claim 2, in which the duct extends throughout the pedestal, another fiber optic cable being passed through said duct to distribute light to another ornamental lighting device.
Claim 5
Dependent Claim
30 words
An ornamental lighting device as claimed in claim 1, in which the retainer means comprises at least two retainer members mounted on inner surfaces of the facing light transmitting panels.
Claim 6
Dependent Claim
41 words
An ornamental lighting device as claimed in claim 1, in which the retainer means comprises guide grooves formed in an inner surface of at least one of the light transmitting panels, the optical fibers being individually received in said guide grooves.
Claim 7
Dependent Claim
26 words
An ornamental lighting device as claimed in claim 1, in which an inner surface of one of the facing light transmitting panels is a mirror surface.
Claim 8
Dependent Claim
31 words
An ornamental lighting device as claimed in claim 1, in which each of the optical fibers is provided with light diffusing means for diffusing light which propagates through the optical fiber.
Claim 9
Dependent Claim
41 words
An ornamental lighting device as claimed in claim 7, in which the light diffusing means comprises a light diffusing material deposited on the optical fiber and having a refractive index which is larger than a refractive index of the optical fiber.
Claim 10
Dependent Claim
25 words
An ornamental lighting device as claimed in claim 7, in which the light diffusing means comprises grooves formed in a surface of the optical fiber.
Claim 11
Dependent Claim
81 words
An ornamental lighting device for radiating condensed light which propagates through a fiber optic cable, comprising: a pedestal; a single optical fiber supported by said pedestal and optically coupled with the fiber optic cable to be supplied with the condensed light; retainer means for retaining said optical fiber in a spiral form; and a pair of light transmitting panels mounted on the pedestal and mounting said retainer means to hold said optical fiber in sandwich array between said light transmitting panels.
Claim 12
Dependent Claim
81 words
An ornamental lighting device for radiating condensed light which propagates through a fiber optic cable, comprising: a pedestal; a single optical fiber supported by said pedestal and optically coupled with the fiber optic cable to be supplied with the condensed light; retainer means for retaining said optical fiber in a spiral form; and a pair of light transmitting panels mounted on the pedestal and mounting said retainer means to hold said optical fiber in sandwich array between said light transmitting panels.
Claim 13
Dependent Claim
22 words
An ornamental lighting device as claimed in claim 10, in which the retainer means comprises a pair of generally cruciform retainer members.
Claim 14
Dependent Claim
98 words
An ornamental lighting device for radiating condensed light which propagates through a fiber optical cable, comprising: a pedestal; a plurality of optical fibers supported by said pedestal and optically coupled with the fiber optic cable to be supplied with the condensed light; retainer means for retaining said optical fibers substantially in oblong loops each of which is substantially symmetrical with respect to a vertical which apsses through the pedestal; and a pair of light transmitting panels mounted on the pedestal and mounting said retainer means to hold the optical fibers in sandwich array between said light transmitting panels.
Claim 15
Dependent Claim
98 words
An ornamental lighting device for radiating condensed light which propagates through a fiber optical cable, comprising: a pedestal; a plurality of optical fibers supported by said pedestal and optically coupled with the fiber optic cable to be supplied with the condensed light; retainer means for retaining said optical fibers substantially in oblong loops each of which is substantially symmetrical with respect to a vertical which apsses through the pedestal; and a pair of light transmitting panels mounted on the pedestal and mounting said retainer means to hold the optical fibers in sandwich array between said light transmitting panels.
