Abstract

Abstract A device for effecting multiple light transmission from a single light source. The light source is a light bulb located at the focal point of a reflector which bulb emits light rays which are reflected from the reflector at an oblique angle to its transmission axis. Light-transmitting members are spaced in front of the bulb and arranged concentrically around, and at oblique angles to the transmission of axis of the reflector. In this manner the light-transmitting member will receive and transmit the maximum amount of light from the reflector.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 81 words
A multiple light-transmission device comprising a single unitary light reflecting means reflecting rays at an oblique angle to its principal axis and having a light-bulb-receiving means for receiving a light bulb therein, mounting means on the reflecting means, and light-transmitting members having ends secured in the mounting means and each said transmitting member positioned at the same oblique angle therein relative to the principal axis of said reflecting means to receive the maximum amount of light reflected from the reflecting means.
Claim 2
Dependent Claim 81 words
A multiple light-transmission device comprising a single unitary light reflecting means reflecting rays at an oblique angle to its principal axis and having a light-bulb-receiving means for receiving a light bulb therein, mounting means on the reflecting means, and light-transmitting members having ends secured in the mounting means and each said transmitting member positioned at the same oblique angle therein relative to the principal axis of said reflecting means to receive the maximum amount of light reflected from the reflecting means.
Claim 3
Dependent Claim 31 words
A multiple light-transmission device according to claim 1 wherein means are provided on said reflecting member and said mounting means to removably secure said reflecting member and said mounting means together.
Claim 4
Dependent Claim 36 words
A multiple light-transmission device according to claim 1 wherein means are provided on said mounting means and the ends of said light-transmitting members to removably secure the ends of said light-transmitting members in said mounting means.
Claim 5
Dependent Claim 17 words
A multiple light-transmission device according to claim 1 wherein said reflecting member has an ellipsoidal reflecting surface.
Claim 6
Dependent Claim 20 words
A multiple light-transmission device according to claim 1 wherein said mounting means is provided with openings to prevent high heat.
Claim 7
Dependent Claim 29 words
A multiple light-transmission device according to claim 1 wherein light-filtering means is disposed between said light bulb and the ends of said light-transmitting members to filter out unwanted spectra.
Claim 8
Dependent Claim 132 words
A light system comprising a socket member for receiving a light bulb therein, a single unitary light-reflecting means extending outwardly from said socket member for reflecting light rays emanating from said light bulb at an acute angle relative to its principal axis, a series of light-transmitting members, mounting means on said light-reflecting means to mount ends of said light-transmitting members to receive the reflected light from said light-reflecting means, means securing ends of the light-transmitting members on said mounting means with ends of said light-transmitting members being disposed to receive a maximum amount of light rays, said light-transmitting members being positioned at the same acute angle with respect to the transmission axis of said light-reflecting means and means mounting other ends of the light-transmitting members adjacent areas to utilize the light therefrom.
Claim 9
Dependent Claim 132 words
A light system comprising a socket member for receiving a light bulb therein, a single unitary light-reflecting means extending outwardly from said socket member for reflecting light rays emanating from said light bulb at an acute angle relative to its principal axis, a series of light-transmitting members, mounting means on said light-reflecting means to mount ends of said light-transmitting members to receive the reflected light from said light-reflecting means, means securing ends of the light-transmitting members on said mounting means with ends of said light-transmitting members being disposed to receive a maximum amount of light rays, said light-transmitting members being positioned at the same acute angle with respect to the transmission axis of said light-reflecting means and means mounting other ends of the light-transmitting members adjacent areas to utilize the light therefrom.
Claim 10
Dependent Claim 100 words
A multiple light-transmission device comprising a light-reflecting surface in the form of a hollow figure of revolution about a principal axis and having a focal point substantially at which a light source may be positioned; said light-reflecting surface being so shaped as to transmit substantially all the light rays to a second focal point, a plurality of light-transmission rods each having an end surface spaced from the second focal point, the respective end surfaces being positioned at such an angle to the light rays which they intercept, as to transmit the maximum amount of light reflected from the reflecting surface.
Claim 11
Dependent Claim 100 words
A multiple light-transmission device comprising a light-reflecting surface in the form of a hollow figure of revolution about a principal axis and having a focal point substantially at which a light source may be positioned; said light-reflecting surface being so shaped as to transmit substantially all the light rays to a second focal point, a plurality of light-transmission rods each having an end surface spaced from the second focal point, the respective end surfaces being positioned at such an angle to the light rays which they intercept, as to transmit the maximum amount of light reflected from the reflecting surface.
Claim 12
Dependent Claim 30 words
A multiple light-transmission device according to claim 8 including a mounting member provided with means for supporting said rods with their end surfaces in confronting relation to the light rays.
Claim 13
Dependent Claim 19 words
A multiple light-transmission device according to claim 9 further including means for supporting the mounting member on the reflector.
Claim 14
Dependent Claim 16 words
A multiple light-transmission device according to claim 8 wherein the light-reflecting surface is elliptical in shape.
