Claims (1)

CLAIMS The present claim refers to the future implementation of a particular umbrella cover which provides a specific feature suitable for making it suitable for the protection and safety of the individual in particular circumstances of poor visibility, for example when it rains in the evening and at night or in other similar conditions. . It is common that motorists, traveling by car at night on urban or extra-urban roads in such conditions, do not have the clear perception of pedestrians or cyclists in motion. The prototype umbrella of my patent provides for the construction of the cover in high visibility material in night conditions. In particular with respect to the UNI EN 471 standard, the official version of the European standard EN 471, in Italian, translated by UNI and which specifies the requirements for clothing capable of visually signaling the presence of the user in dangerous situations, in any condition. daylight and vehicle headlights in darkness (including performance requirements for color, retro-reflection, minimum areas and material arrangement, test methods for testing the effectiveness of materials and devices as a whole). The idea of this patent arises from the observation in the first place of the aforementioned rule, which must also be applied to protect pedestrians and cyclists equipped with ordinary umbrellas who, in night conditions of poor visibility and in the obvious case of rain, are unable to be well identified by drivers of motor vehicles while traveling along the roadway or crossing carriageways where the lighting characteristics are lacking. The primary objective is therefore to safeguard the safety of the individual through the application of known scientific phenomena that can provide a solution to the problem. Contrary to other solutions proposed up to now that provide for lighting technologies with optical fibers, LEDs and in any case through the use of electrical / electronic devices or circuits, this patent uses commonly known natural technologies and commonly used materials with characteristics of refractivity, fluorescence, phosphorescence. . Below are the scientific principles on which the utility model is based. Refractive The refracting material is a reflector which has the characteristic of reflecting light in the same direction from which it comes. An ideal refractor is able to return the light to the source, whatever the angle of incidence. the source only if the angle of incidence is 90 degrees. Let us suppose for simplicity that we take into consideration a two-dimensional situation (Fig. 1) in which the incident beam belongs to a determined plane. In this case, to reflect the beam in the direction of origin, whatever it is on the predetermined plane, it will be sufficient to place two mirrors at 90 degrees to each other, perpendicular to the plane containing the beam. The beam will strike the first mirror at an angle β and will be reflected at the same angle towards the second mirror. Since the mirrors are perpendicular, the angle of incidence and reflection on the second mirror will be 90-β. It follows that the angle of reflection with respect to the first mirror will be equal to β and therefore the beam will be reflected in the same direction from which it came. beam will be sent back to the source wherever it is on the semi-plane delimited by the two mirrors. The same considerations can be made in the three-dimensional case using three mirrors placed at 90 degrees to each other, such as the three internal faces of a corner of a cube. obtain surfaces of variable dimensions according to the needs (by observing a reflective surface it is easy to see how it is in fact made up of several adjacent cells). In case of need of great reflection capacity, reflectors consisting of a single glass prism of larger dimensions with internal mirror surfaces can be used. The use of reflectors is widespread and finds application. Fluorescence Fluorescence is the property of some substances to re-emit the radiation received at a lower frequency, in particular to absorb ultraviolet light and emit it visible. We see an example of this process in all materials that contain fluorescent pigments, such as in the ink of highlighters and fluorescent paints. The fluorescent properties of an object often become evident with the use of a Wood Lamp, but depending on the materials a shorter wavelength may be required. Fluorescence is one of the two radiative processes, together with phosphorescence, with which relaxation of an excited molecule can occur.The distinction between the two processes was originally made on the basis of the life time of the radiation: in fluorescence the luminescence ceases almost immediately after eliminating the exciting radiation, while in phosphorescence the radiation continues to be emitted, at least for a short period of time, even after eliminating the exciting source. transitions responsible for the emission of radiation. In fluorescence the radiation is generated by virtue of transitions between states with the same spin multiplicity (for example S \ → So), while in phosphorescence the transition involved involves variation of the spin multiplicity: the most frequent case are triplet-singlet transitions Phosphorescence Phosphorescence is a radiative emission, characteristic of some chemicals as a result of electronic excitation, resulting from the decay to quantum levels of lower energy. It is distinguished from fluorescence because in the latter the effect is immediate and is interrupted as soon as the energy source is interrupted, while in the phosphorescence the effect continues even after. The principle, simplified, is the same: an energy source, usually composed of visible light or ultraviolet radiation, excites the atoms, causing some electrons to jump on an outermost orbit. When these return to the internal orbit they emit light.This phenomenon is observed as the electrons present in the fundamental orbital level pass, through the action of an excitatory source, which can be for example a photon, to a higher singlet level (unitary spectral multiplicity , presence of paired electrons). Subsequently, in addition to other phenomena of non-radiative decay, the return to the stable ground state with radiant emission can occur essentially in two ways: a singlet-single-click conversion or, alternatively, a transition to a quantum-mechanical configuration of the triplet type (spectral multiplicity three, presence of two unpaired electrons) and the subsequent decay to the lower singlet state. In the first case there is a fluorescent radiant emission while in the second the phosphorescent emission phenomenon occurs. In addition to the already described fundamental difference existing between the two luminescent phenomena, it should be noted that the decay that produces phosphorescence is temporally longer (10 <'> s vs 10 <'> - 10 <'12> s) than that involving fluorescence : the phosphorescence follows the excitation with a certain delay and lasts even a few minutes later. The emerging radiation is less energetic, therefore characterized by a longer wavelength, since during the de-excitation process, part of the energy is used to re-establish the singlet state, other is lost during the passage of the electron in the vibrational sub-levels of the excited state. The decrease in temperature hinders the competitive relaxation processes and leads to an increase in the phosphorescent quantum efficiency, efficiency Φ defined from the equation Φ = ΦΡ / ΦΑ where Φρ and ΦΑ are, respectively, the quanta of radiation emitted and absorbed. tances that under normal conditions are not phosphorescent working at the temperature of liquid nitrogen.
