Description
June 16, 1931. C. LOEB SPECTRUM LAMP Filed oct. 18. 1929 Wav/22% Patented June 16, 1931l UNITED gSTATES PATENT OFFICE CARL LOEB, F CHICAGO, ILLINOIS SPECTRUM LAMP Application filed October 18, 1929. Serial No. 400,630.
The invention relates to therapeutic lamps and more particularly to a spectrum lamp' l0 the lamp on an object.
These lamps are, however, expensive to manufacturenor can they, be handled withA ease and accuracy. Furthermore, complete; ness of spectrum 1s obtained by sacrificing intensity thus partly defeating the elfectiv'eness of the lamp. v
It, therefore, constitutes the principal object of the invention to provide a spectrum lamp which is of extremely simple construction and yet highly andmeliably effective for the purpose to which it is assigned.
A further object aims at providing a lamp in which a light is completely dispersed and a single means is provided for selecting the desired color for projection.
A still further object aims at providing adjustable means for selecting desired rays from a spectrum for projection.
Another object aims at providing a spectrum lamp in which the desired color of a spectrum is simultaneouslyselected and projected. y
Still another object embraces the provision of a spectrum lamp where the means for selecting the particular color is arranged at a point utilizing the completion and intensity of the spectrum in order to project on an object.
With these and other equally important objects in view which will become apparent from a perusal of the invention, the latter comprises the means described in the following specification, particularly pointed out in r the claims forming a part thereof and illus- .4 trated in the accompanying drawing, 1n
which,`
The figure is a more or less diagrammatic horizontal. section of an apparatus constructed in accordance with my invention.
Referring to the drawing, the lamp comemployed I prises a tube 10 which at one end is equipped with an arc light 11 or any other light source and this light is at the focal point of a collimating lens 12. The rays emanating from the arc light or other light source are refracted to continue in parallel lines and are incidental on the proximate face 18 of a single prism 14, which is arranged in a ,cas 4 ing 15 open at the front and rear ends to provide a passage for the rays. The prism may be made of glass or quartz or a combination of liquid and glass or liquid and quartz or instead of a prism a ruled grating may be The rear end 16 of the casing 15 is arcuate and is covered by an arcuate plate 17, which v on the top and bottom has horizontal seg mentary extension 18 secured by pivots 19 to the casing 15, so that the plate 17 may be turned about the pivots 19 to be swung into any desired position relative to the casing. The plate 17 is formed with a unitary tube 20 extending therefrom centrally to said plate, and the tube is provided intermediate its ends with a diaphragm 21 having a comparatively wide central slot 22. Near the other end, the tube is provided with a projecting lens 23.
In use, the rays emanating from the arc light 11 or other light source are refracted from the collimating lens 12 in parallel lines and by means ofthe prism 14 are dispersed into a spectrum. Thereupon, the plate 17 is actuated and the desired colors such as red, green, blue or violet. or any other desired color is selected to pass through the slot 22 of the diaphragm 21 and said color is proj ected on an object.
Attention is called t0 the fact that the diaphragm 21 is arranged at considerable distance from the prism 14 so that allthe colors of the spectrum are available for selection and a broad band of the selected color may pass through the slot which simultaneously is projected by the lens 23.
It is noteworthy that a narrouT intense spectrum is first produced and permitted to pass the slot 21 of diaphragm 2O and thereupon the band is widened by projection to effectively act on the object which is to be subjectedto the influence of the selected color.
The expression color is not used in a. restricted sense vbut includes electro-magnetic waves, wave frequencies and the like.
While the drawing shows the preferred embodiment of the invention, numerous changes and variations may be made without departing from the spirit of the invention.
I, therefore, do not limit myself to the arrangement of parts nor to their construction `as shown but claim my invention as broadly .as the state of the 'art permits.
I claim: 1. A spectrum lamp, including a casing,
means for producing a complete spectrum in said casing, and a second casing pivotally connected to said first casing and having means for selecting a color band from said spectrum and projecting it onto an object.
2. A spectrum lamp, including a station ary casing, means for producing a complete spectrum in said casing, and a second casing movable on said stationary casingl and interposed in thepath of said spectrum, said second casing'havino' means for selecting and projecting a color and of said spectrum.
3. A spectrum lamp, including a stationf ary casing, means for producing a spectrum in said casing, by a simple refraction, and a second casing movable on said stationary casing and interposed in the path of said spec`u trum, said second casing having means for simultaneously selecting and projecting a color band of said spectrum. p
In witness whereof I aix my signature.
CARL LOEB.
