Embodiment Construction

[0055] figure 1 and figure 2 It is a figure which shows the structure of the ultraviolet irradiation apparatus of the 1st Example of this invention. figure 1 is a cross-sectional view showing a direction perpendicular to the length direction of the lamp; figure 2 is a cross-sectional view along the longitudinal direction of the lamp. again, figure 1 and figure 2 Both are omitted to indicate the power supply unit.

[0056] like figure 1 and figure 2 As shown, the ultraviolet irradiation device of this embodiment is provided with: a light source unit 1 having a lamp 1a and a reflector 1b reflecting ultraviolet rays from the lamp 1a, a refrigerator 2 (radiator) for cooling the cooling air, and a surrounding The air blower 3 (blower) which generates cooling air is three units and has the housing 6 which has the transmission window 6a which transmits the ultraviolet-ray emitted from the light source part 1. As shown in FIG. A gap is provided between the housing 6 and th...

Abstract

Provided is an ultraviolet-ray irradiation device in which, in the light irradiation device to cool a light source part by circulation cooling air, the portion heated by the cooling air increased in temperature is not exposed to the outside, and the device is not made large in size, and the floor area occupied by the device can be made small. The light source part (1) having a lamp (1a) and a reflecting mirror (1b), a blower (3), and a cooling unit (2) to cool cooling air are installed in a case (6) having a light transmission window. The cooling air sent from the blower (3) is introduced into the light source part (1) passing through a ventilation passage formed between the above light source part (1) and the case (6), cools the lamp (1a) and the reflecting mirror (1b), and is introducedinto the cooling unit (2) through a cooling air passing hole (1c) provided at the reflecting mirror (1b). The cooling air cooled by the cooling unit (2) is returned to the blower (3).

Description

technical field [0001] The present invention relates to an ultraviolet irradiation device that circulates cooling air for cooling lamps and irradiates ultraviolet rays. Background technique [0002] UV rays emitted from discharge lamps such as high-pressure mercury lamps or metal halide lamps are irradiated on adhesives, paints, inks, photoresists, etc. that are sensitive to ultraviolet rays to harden or dry them, or vice versa. Various treatments such as melting or softening. [0003] In order to prevent heating during lighting, the lamp is cooled by cooling air. Recently, a device for circulating cooling air in order to reduce consumption of cooling air has been proposed. For example, devices described in Patent Document 1 and Patent Document 2 are known. [0004] In Patent Document 1 figure 1 In the above, it is disclosed that the cooling air that cools the light source lamp 11 or the reflector 12, etc., is supplied to the circulating air path through the exhaust blower...
