Problems solved by technology

[0036] However, in the conventional method of supporting the lamp by clamping the base of the lamp with the base holding member, the center position of the lamp does not coincide with the first focus position of the reflector, and the illuminance uniformity is ±2% to ±3%. , cannot achieve the required optical characteristics

Embodiment Construction

[0102] figure 1 It is a figure which shows an example of the light irradiator provided with the rod-shaped discharge lamp which concerns on the Example of this invention.

[0103] The same figure is a cross-sectional view in a direction parallel to the length direction of the lamp, which is the same as that explained in the background Figure 11 , Figure 12 The same components of the components shown are given the same symbols.

[0104] 40 is a light irradiator that irradiates light that includes ultraviolet rays. The inside of the light irradiator 40 is divided into a wind tunnel 43 and a lamp arrangement space 44 for disposing the discharge lamp 50 through a partition wall 42. Below the lamp arrangement space 44, a rectangular Opened light exit port 41 .

[0105] In addition, in the lamp arrangement space 44 , a gutter-shaped reflector 45 having a reflective surface having an elliptical cross-section and reflecting light from the lamp 50 is installed along the extending ...

Abstract

The invention provides light whose center is superposition of first focus position. The light comprises: discharge light, including a pair of electrodes, and bases on two end; a group of light supportcomponents, which are located on the both sides of the discharge light, and supports the light in the base; and light reflecting the light from the discharge light, which forms concave convex parts in the position of intersection point of end surface of base and imaginary connecting line of the pair of electrodes. A pair of opposite concave convex parts are formed and located on the front end ofthe base, and the imaginary connecting line of whose end surfaces is coincident to the first focus position.

Description

technical field [0001] The present invention relates to a structure of a light irradiator and a discharge lamp attached to the light irradiator. technical background [0002] Using a light irradiator equipped with a lamp that emits ultraviolet rays, it is widely used in various fields to irradiate resins, adhesives, paints, inks, photoresists, etc. with ultraviolet rays to perform various treatments such as hardening, drying, melting, and softening. , Patent Document 1 exists, for example, as a prior art for the structure of a light irradiator for such a process. [0003] As lamps that radiate such ultraviolet rays, discharge lamps such as rod-shaped high-pressure mercury lamps and metal halide lamps with large outputs are often used because the treatment can be performed in a short time. [0004] A metal halide lamp refers to a lamp in which a gas containing a plurality of metals is encapsulated, and in addition to mercury, iron, mercury iodide, thallium iodide, etc. are e...
