Light irradiation device

Abstract

The invention provides a light irradiation apparatus capable of reducing constituents detached from the light irradiation apparatus as much as possible when a lamp is replaced and achieving replacing operation of the lamp in a closed state of the gate of the light irradiation apparatus so as to make the replacing operation of the lamp easy. The replacing operation of the lamp comprises a long cylindrical housing (2) equipped with a light irradiation window (21), a lamp unit (5) equipped with a lamp (3) and a lamp support (4), and a gate member (7) moved between a closed position (P) shielding light and an open position (Q) passing the light. When a reflection board (4) and the gate member (7) at the closed position (P) are left in the housing (2), the lamp unit (5) can be detached from the end portion of the long side direction of the housing (2) along the long side direction of the housing (2).

Description

technical field [0001] The present invention relates to a light irradiation device used for curing treatment of, for example, resins, paints, inks, or adhesive materials. Background technique [0002] As shown in Patent Document 1, an ultraviolet irradiation device is provided as the light irradiation device. The ultraviolet irradiation device has a lamp unit configured by disposing an ultraviolet lamp and a reflector on a base, and a housing for accommodating the lamp unit. The lamp unit is pulled out from the housing. In this ultraviolet irradiation device, replacement work of other components such as ultraviolet lamps and reflectors incorporated in the lamp unit can be quickly performed. [0003] However, in the above-mentioned light irradiation device, although the ultraviolet lamp can be replaced at any place by pulling the lamp unit out of the housing, even when the lamp unit is equipped with a reflector without replacing the reflector, it is necessary to The reflect...

AI Technical Summary

Problems solved by technology

[0005] However, in the ultraviolet irradiation device provided with the above-mentioned lamp unit, after use, the lamp is cooled by turning off the power supply and temporarily closing the shutter mechanism, and then after turning on the power again and opening the shutter mechanism, it is necessary to pull out the lamp unit, Not only consumes unnecessary power, but also makes the replacement operation cumbersome

It should be noted that when the shutter is stopped with the open state after the use of the ultraviolet irradiating device, problems such as dust outside the device adhering to the ultraviolet lamp and the reflector occur.
