Abstract: The xenon lamp has a light output which remains constant for a long operating period. The wall of the bulb is not blackened as the metallic vapour or volatile substances will be adsorbed. The adsorber consists of magnetic pieces, so that only the magnet will become blackened. The magnets (8, 8') are fitted inside the bulb on the same fitting as the electrodes (9, 9'). The magnets are in the form of partially slit rings. They are located between the discharge section of an electrode inside the bulb and the end of the tube along the same axis. The volatile substances or metallic vapour are produced by the increased temperature of the electrode during the light emission of the discharge process. They will be attracted by virtue of the magnetic field and adsorbed under magnet so that these particles or substances will not be able to settle on the inside of the bulb.

Abstract: A light intensity monitoring and adjusting apparatus for a light-fastness testing apparatus having a xenon lamp and a power source circuit for supplying power to the lamp. The monitoring and adjusting device has an optical fiber light guide having three bundles of optical fibers therein. One end is directed toward the xenon lamp for picking up the light emitted therefrom and the other end is connected to a light-receiving means including a plurality of three light-receiving elements, one for ultraviolet light, one for visible light, and one for infrared light. Each produces an electrical signal corresponding to the intensity of the light received. The apparatus has a source of reference voltage and a voltage comparator coupled to the source of reference voltage for comparing input voltages from the light-receiving elements with the reference voltage. A voltage adjusting means is coupled to the power source circuit for adjusting the voltage supplied to the lamp and is driven by the output of the voltage comparator to change the voltage supplied to the lamp to bring the intensity of the light produced by the lamp to a value corresponding to the light intensity value represented by the reference voltage, whereby the intensity of light in a spectrum emitted by the lamp can be kept constant for testing specimens for light-fastness under constant conditions.

Abstract: When xenon lamps are used for tests of the weathering resistance and fastness against light, it is most desirable to keep the quantity of light emitted constant. This can be done and the lamp can be made immune against temperature fluctuations by acting on the temperature dependent properties of the light reception part. The light from the lamp is received at one end (3) of a bundle (1) of fibre optical glass guides (1), each of 2-3 mm diameter, and coated by a vacuum evaporated aluminium film (2). At the exit end (4) the light is received by a silicon photocell (8) and thermistor (9) bonded to a ring (10). After amplification the signal is compared with a reference signal and a motor is actuated to adjust a voltage regulator for the xenon lamp voltage.

Abstract: A carbon electrode comprises (a) a C bar electrode having a discharge tip at one end and a holding section at the other, (b) a coating of Al or predominantly Al-alloy on all peripheral surfaces of the bar except the discharge tip and (c) a second coating of Al2O3 and Si oxide on all peripheral surfaces except the discharge tip and holding end. The electrodes are useful for sunshine or ultra-violet carbon arc lamps used for fading and weathering tests on paints or fabrics. Electrodes life is increased by up to 20%. As the C is consumed and Al melts, the molten Al combines with the oxide and forms a vitreous ceramic which descends under gravity so no molten metal coats the lamp envelope and reduces transmittance. The exhaust contains no toxic materials. The ultraviolet output is about the same as that of lamps using conventional C electrodes, but infra-red output is reduced.
