Abstract

PURPOSE:To manufacture a pulse light source which can widely irradiate an object having a wide area by covering plural pairs of anodes and cathodes, and plural trigger electrodes, with a light-transmitting material so as to make a special gas ambiance. CONSTITUTION:In a housing which consists of a light-permeable material sealing a rare gas such as a heavy hydrogen, krypton, and xenon, plural pairs of anodes 1 and cathodes 2 to discharge, and plural trigger electrodes 3 to expedite the light emission are provided, and a belt-form pulse beam source is formed by connecting them to a capacitor and a power source in the outer side. In this case, the anodes 1, the cathodes 2, and the trigger electrodes 3, are arranged in one line or in plural lines, and placing intervals to prevent a leakage of voltage to the neighboring electrodes in their combination. Consequently, a pulse light source which can irradiate the wide area on the surface of a substance is obtained by moving the substance.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pulse light source for illuminating objects having a wide area.

[0002]

2. Description of the Related Art As a conventional pulse light source, there is a point light source having an anode, a cathode and a trigger electrode. It is possible to illuminate a small surface locally, but the price is expensive. In addition, even if a plurality of point light sources are arranged side by side to irradiate a required area, there is a drawback that there is physically a gas-filled material wall between the light sources as an adverse effect for making the light uniform. . Recently, there are various pulsed lasers such as excimer lasers as pulsed light sources. However, in the case of lasers, the beam size is small, so in order to irradiate a required area, the beam must be scanned while irradiating the beam. In addition, since the energy density of the beam is not constant, it is extremely difficult to obtain a uniform irradiation density, and there are drawbacks such that the apparatus itself is expensive.

DISCLOSURE OF THE INVENTION The present invention has been studied in order to solve the above-mentioned problems, and is applied to the application of chemically and physically modifying the surface by irradiating light. The present invention provides a very simple and useful light source.

[0004]

The present invention is directed to a set of housings which are light transmitting materials for containing noble gases such as deuterium, krypton and xenon, and a plurality of housings for discharging into the housings. The basic structure consists of an anode, a plurality of cathodes, and a plurality of trigger electrodes for promoting light emission. Further, a capacitor having a predetermined capacity and a power supply are prepared as an external configuration for emitting a light source. The anode, the cathode, and the trigger electrode forming each pair are arranged in one row or a plurality of rows at intervals such that voltage does not leak to an adjacent electrode between combinations of these electrodes. The arranged electrodes are connected to an external capacitor or a power source so that the electrodes can be fired at the same time, and light is emitted at a required time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an arrangement of an anode, a cathode and a trigger electrode in a line. By moving an object irradiated with light, it is possible to irradiate a wide area on the surface. It can be used as an application to carry out surface modification of woven fabrics or to physically or optically change a wide surface of a polymeric material.

Further, as a further development of FIG. 1, by arranging the anode, the cathode and the trigger electrode in a plurality of rows so as to irradiate a wider plane, the object to be irradiated with light is continuously irradiated. In the case of moving, it is possible to irradiate the same place with light multiple times, or if the object that irradiates light has intermittent motion, it is possible to irradiate a large area at the same time and to irradiate light with multiple times. It can be used for devices that can adjust the amount of accumulation.

[0007]

As described above, the conventional irradiation of a large area has various drawbacks in the pulse light source, but by using the above-mentioned pulse light source, a completely new concept that neither a point light source nor a laser is used. Therefore, it is possible to provide a simple light source as a means capable of irradiating a large area in a pulsed manner.
