Abstract

A lighting control method of lighting device and lighting device, capeble of holding lightness of the lamp injected light as a certain value, furthermore, capable of correcting detection sensitivity of light sensor with deteriorated sensitivity automatically. First recording total lighting time of the lamp 1 on IC tag 1a mounted on the lamp1, uses as specified target power of target lightness to light the lamp1, then measuring the lightness through a light sensor 15. If the reduction of lightness exceeds a certain percentage, the power supplied to lamp 1 will be modified. The modification is a modification schedule ruled by refering to relationship of the total lighting time and modified power, calculating a modified power corresponding to the total lighting time, and controlling the power supplied to the lamp1, Furthermore, correct lightness data of light of each lamp is calculated by undeteriorated light sensor which being recorded onto the IC tag Ia. When the lamp is mounted onto the device, the lightness data is compared with lightness outputted by light sensor 15 arranged on the lighting device, and output of the light sensor 15 is corrected.

Description

technical field [0001] The present invention relates to a lighting control method and a light source device for a light source device that emits light such as ultraviolet rays, and particularly relates to controlling the power supplied to the light source in response to changes in the light output of the light source over time. A lighting control method of a light source device and a light source device for correcting data output from a detection unit for detecting illuminance of a light source with data stored in an IC tag provided in a light source. Background technique [0002] UV / O 3 The cleaning method is used as a combination of ultraviolet rays and ozone (O 3 ) are widely used in combination with cleaning methods, the purpose of which is, for example, by irradiating ultraviolet rays on the surface of LCD substrates or semiconductor substrates to cut off molecular bonds such as organic compounds adhering to the substrate surface, thereby removing the adhering substrat...
