Definitions
- the proportions of these substances in the gas of the discharge atmosphere under normal running or operating conditions may vary appreciably because of the variation of the cold point temperature due to variations in external conditions such as those of the line voltage and of the ambient temperature.
- This temperature characteristic is found to vary from one lamp to another of the same manufacture, lbecause of small but inevitable deviations in their dimensions. It is also found to vary for the same lamp, depending on the supply voltage and the supply apparatus.
- the spectral distribution of the radiation can be caused to vary, for example, in order to favour either the obtaining of blue light, or the obtaining of green light, or the obtaining of red and violet light, respectively by increasing the proportions of indium iodide, thallium iodide and gallium iodide.
- the discharge vessel is advantageously equipped with tungsten electrodes comprising an addition of thorium in metallic form as an element which easily emits electrons.
- This thorium may in addition contribute to the light emission by production of thorium iodide from iodide in excess, coming from the triiodide.
- gallium iodide emitting red light of Wavelengths 6414 and 6397 A.
- These violet radiations which are less efficient from the point of view of light production, can advantageously be employed for exciting a tluorescent material deposited in a bulb containing the mercury and iodides vapour tube.
- This fluorescent material which must have good eiciency at the high temperature of the bulb, will for example be magnesium uorogermanate emitting red light or preferably strontium and optionally zinc orthophosphate activated with tin, an emitter of orange and yellow radiation and contributing to the balance of the light in the different parts of the spectrum.
- FIGURES 1 and 2 show diagrammatically and by Way of example two lamps according to the invention.
- the silica tube 1 is mounted axially in a cylindrical envelope 6 of hard glass in known manner by means of a metal support.
- heat-insulating elements 4, 14 which are formed by a metal strip of polished nickel insulated from the end of the lamp by a thermal insulator, such as for example silica wool. This permits the heat losses through the ends of the tube to be greatly reduced, especially when these latter comprise flat pinched portions with a large area. In this way, a suciently high temperature, of the order of 600 C., is maintained at the cold point of the tube, thus avoiding the possible condensation of the products being used and permits a more rapid warming-up.
- the bulbs 6 and 8 may be advantageous to form the bulbs 6 and 8 of slightly yellow glass or to deposit inside these bulbs a layer which is formed wholly or in part by a yellow pigment; in this way, a light is obtained which has a more accentuated component in the long wave lengths.
- the lamps according to the invention have the above advantages, as well as a high e'iciency, without it being necessary to dissipate therefrom a high power, relatively to their dimensions; there are thus avoided the disadvantages of a high temperature due to a high load: rapid devitrification of the silica forming the wall of the tube, rapid destruction of the tube, more rapid physical and chemical phenomena and probably opaque metals deposition on the wall of the tube may be with a surface attack of the silica.
