| abstract | 305,963. Murray, G., and Simpkins, V. O. Nov. 10, 1927. Ornamental illuminations, lamps for.-In a lamp for decorative illuminations or for advertising purposes, light is projected through a diffusing and distributing member constituted by a transparent or translucent hollow body containing liquid in which a gas is generated or released to produce changing light effects. In the form shown in the Figure, light from an electric lamp bulb 1 is projected by a reflector 3 into a spherical vessel 4 containing a liquid 5 and provided at its top with a small hole for filling purposes and to allow of the escape of the gas. Preferably the liquid is an electrolyte and a pair of platinum or other electrodes 6, 6<a> are connected in series with the bulb 1 so as to generate gas by dissociation of the electrolyte. The latter may consist of slightly acidic water from which ozone is released, or water containing a pinch of glauber salts and small quantities of osin and erythrosine or fluorescin. The liquid may be coloured by means of a dye, such as congo red, and an indicator such as methylorange or phenol phthalein may be employed to produce more or less localized colour changes. Small particles may be suspended in the liquid to give irridescent effects. Either or both electrodes may be in the form of a word, design, or other advertisement, and the permanence of the electrolyte may be ensured by means of a buffer electrolyte. 'The electrodes, electrolyte, and current intensity may be so chosen as to cause a scintillating luminiseence over the surface of the electrodes. When alternating current is used the electrodes are connected to the secondary of a step-down transformer and the electric lamp bulb may be connected across the supply mains. A number of such lamps may be combined to produce a variety of colour changes. |
