Light energy, its physics, physiological action and therapeutic applications . isms for radiant energy baths, whether local or gen-eral, may be carried to a rheostat by means of which the cur-rent may be carefully graduated and the lamps made to glowmore or less brightly according to the light intensity using concentrated incandescent light energy, it is betterto thus control the intensity of the light of the group ratherthan to do so by cutting out one or more lamps. InFreunds apparatus the reflector on its open side has col-ored glass filters or fluids. This apparatus may be fixed toa stand. For the extremities there are used drum-shaped boxes(see Fig. 30) into which groups of lamps, 2, 4, 6, 8 ormore, according to the size of the part, the condition, and thedegree of light intensity necessary, are placed. In these anopening may be cut in the thickest part of the casing, theexact size of the reflector, into which it can then be minor points the construction of these mechanisms isdifferent but the essential principle is the same in all.
