Abstract

The appts. comprises a casing containing a lamp providing wood light, or black light, and a fluorescent tube providing an output simulating daylight, with three separate circuits each containing red, orange, yellow, green, blue, violet, red and white layers. Four rows of interrupter switches (e, f, g, h) and three colour variation controls (i, j, k) divided into six divisions are provided in the front of the casing for controlling the light sources inside the casing. The inside of the casing is viewed through a longitudinal slot (d).
