Problems solved by technology

[0004] However, for applications such as lamination by curing an ultraviolet-curable adhesive sandwiched between two resin materials, since these discharge lamps emit ultraviolet light with a wavelength of less than 300 nm, the resin may be formed from the surface of the resin material. UV degradation

Embodiment Construction

[0028] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0029] figure 1 An ultraviolet irradiation device 100 according to a typical embodiment of the present invention is shown. In the lamp body 20, the ultraviolet irradiation device 100 consists of a high-pressure mercury lamp 1, an elliptical reflector 2 that condenses the emitted light from the discharge lamp, and a plane reflector 3 that reflects the condensed light from the elliptical reflector 2 and guides it to an optical waveguide 22. constitute. The elliptical mirror is made of glass, and its reflective surface is coated with multi-layer evaporated film. The characteristic of the multilayer vapor-deposited film is to reflect ultraviolet light and transmit light from the visible light region to the infrared light region. A high-pressure mercury lamp 1 as a light source is schematically shown in figure 2 Among them, it is made of quartz glass, and consists of a ...

Abstract

The present invention relates to an ultraviolet irradiation device that is capable of highly efficiently converging UV light of 300nm to 400nm, which is suitable for solidification by ultraviolet, on a light incident opening of tiny fiber with a diameter of less than 5mm; a blocking light filter that blocks ultraviolet with the harmful wavelength of less than 300nm is not used; and the ultraviolet of 300nm to 400nm can be effectively radiated on an object. The present invention is characterized in that the device is provided with a high-pressure fluorescent mercury lamp with a pair of tungsten electrodes that are arranged in a discharging container that is formed by quartz glass; mercury of 0.08 to 0.30mg / mm<3>, rare gas and halogen are enclosed in the container; the distance between electrodes is 0.5 to 1.8 mm, which can highly efficiently irradiate the ultraviolet of 300 to 400nm; a light-converging component can converge the light from the high-pressure fluorescent mercury lamp and converge the ultraviolet of 300 to 400nm in an area with a diameter of less than Phi 5mm so as to radiate the irradiated object.

Description

technical field [0001] The invention relates to an ultraviolet light irradiation device, which converges the ultraviolet light radiated by a short-arc high-pressure mercury lamp and irradiates the object to be processed. Background technique [0002] For example, as described in Patent Document 1, light radiated from a light irradiation device is irradiated to an object to be processed such as an adhesive, paint, ink, protective layer, etc., and is cured or dried. Moreover, when the light irradiation process is bonding of a pickup lens for an optical disc or bonding an electronic component to a substrate, it is necessary to irradiate light in a small area; The light emitting part of the light source lamp converges the light of the light source lamp on the light entrance opening of a tiny optical fiber with a diameter of φ5mm or less (less than or equal to), and irradiates the tiny area as the irradiation target. [0003] Conventionally, a high-pressure mercury lamp as descr...
