摘要

An installation for the use of a radiation system designed to excite luminescent tubes by means of high frequency energy to produce the luminescence of these tubes, characterized in that it comprises in combination the following four elements: generator, transmission line, radiator and signs luminous, which are characterized by the following points: a) the generator used is provided with electronic tubes that allow the maintenance of the oscillations and the oscillator control is carried out with the help of a quartz that allows a rigorous control of the frequency used, being rectified and filtered the high voltage obtained to achieve a pure wave; b) the high frequency energy that leaves the generator can be used directly on the radiant system in high impedance; c) the high frequency energy that leaves the generator can be used in low impedance by means of a coupling transformer that adapts said impedance to the output; d) the generator used operates under a frequency of 13,560 kHz and especially in low impedance, that is to say that the low impedance system is the preferred current embodiment; e) a circuit is mounted inside the generator that allows the output of high frequency energy at low impedance which is transmitted to the radiant system with the help of a line of parallel wires; f) inside the generator itself an autoinduction is used that is directly coupled to the high impedance autoinduction of the amplifier tube and through this transformer it is possible to reduce the output voltage to a sufficiently low level to avoid losses by high frequency; g) the high frequency energy radiator is divided into two parts; the impedance adapter system that makes the connection between the connection line and the radiator itself and the radiators; h) a tuning circuit composed of two coupled coils is used at the radiator inlet, the primary being attacked by the low impedance line and the secondary line coupled to the radiator elements and tuned by a capacitor; i) the radiator may be composed of a plate provided with a band or with metal wires; j) the radiator can be composed of parallel wires or single wires; k) the radiator may be composed of an insulating cylinder on which metal bands or wires are attached; l) the radiator can be composed of wires stretched in space; m) the radiator may be composed of any arrangements of any kind intended for the excitation of luminescent tubes by high frequency energy; n) the radiator can be of the projection type in which case the high frequency energy is concentrated in a certain direction and projected by means of beams directed in the direction of the objects to be illuminated, which in this case are placed at a certain distance between the radiant beams and the place of their use; o) in this case, a rotary projector can be used in particular, which allows the rapid and continuous illumination of different letters arranged in a circle; p) the letters or luminous motifs are inspired by the technique of the tubes used in the high voltage light installations, presenting at the same time, however, an essential difference, which lies in the absence of interior electrodes that are normally intended to cause a potential difference within the gas; q) pyrex glass tubes not sprinkled are used in which case the ionisation effect of the gas is then directly noticeable; r) internally coated tubes are used of a deposit based on metallic oxides that become luminescent by the ionization of the gas contained in the tube; s) the gases contained in these tubes or luminous motifs can be indifferently neon, argon, helium, mercury vapor or any other; t) the luminous signs can be fixed by hooks or by the use of electromagnets in which case the letters will be provided with a device that allows them to be fixed by magnetization on special bands provided for this purpose by the radiant system.
