Problems solved by technology
[0006]However, when a plurality of elongated ultraviolet light sources are arranged adjacent to each other, if some of them do not light up for some reason during lighting, if If you continue to irradiate with ultraviolet light, the required irradiation intensity will not be obtained, so poor quality will occur in the ultraviolet light irradiation process.
Therefore, in such extraordinary times, appropriate backup is required, but in the past technology cannot cope with these

Embodiment Construction
[0026] Hereinafter, modes for implementing the present invention will be described with reference to the drawings.
[0027] (the first way)
[0028] figure 1 , is a circuit block diagram of the first embodiment of the ultraviolet light source lighting device for implementing the present invention. In this aspect, the ultraviolet light source lighting device UVO is equipped with the elongated ultraviolet light source UVL, the lighting circuit OC, the non-light detection device D, and the back-up device BA when it is not lit. In addition, the above-mentioned mid-ultraviolet light source UVL, the lighting circuit OC and the non-lighting detection device D are respectively used in multiple groups, and the numbers of 1, 2, 3, ... n are marked at the end of the labels of the respective components in the figure.

The invention provides an ultraviolet light source lighting device which executes backup operations appropriately when one or more elongated ultraviolet light sources go out during the lighting period due to any cause in the configuration where a plurality of elongated ultraviolet light sources are arranged adjacent to each other, and also to provide an ultraviolet irradiation apparatus using thedevice. The ultraviolet light source lighting device UVO comprises: the plurality of elongated ultraviolet light sources UVL which are arranged adjacent to each other so as to combine each emitted ultraviolet light and irradiate a irradiated surface; lighting circuits OC, which turns on the plurality of ultraviolet light sources, respectively; a non-lighting detecting means D for detecting the non-lighting state in the plurality of ultraviolet light sources; and a non-lighting period backup means BA which increases ultraviolet light output by controlling the lighting circuit of the ultraviolet light source adjacent to the ultraviolet light source in the non-lighting state in conjunction with the non-lighting detecting means.
Description
technical field [0001] The present invention relates to an ultraviolet light source lighting device for lighting a plurality of elongated ultraviolet light sources, and an ultraviolet irradiation device using the same. Background technique [0002] Germicidal lamps, metal halide lamps, excimer lamps, and the like are known as elongated ultraviolet light sources. The application of ultraviolet light emitted from an ultraviolet source involves many aspects. [0003] Among the above-mentioned ultraviolet light sources, the excimer lamp is characterized in that it is easy to manufacture in various shapes and sizes, so the size of the irradiation area is not easily limited, and at the same time, it can generate radiation of effective wavelengths. That is, the excimer lamp is a lamp in which a rare gas such as xenon or a halide of a rare gas is silently discharged, that is, a dielectric barrier discharge, so that it produces emission close to the inherent monochromatic color, and...
