なく、バルブ中央部が垂れ下る問題があった。In the case of an ultraviolet irradiation device that is equipped with a heat cutoff filter that allows a cooling medium to flow through the outer peripheral surface of the bulb of a discharge lamp in a horizontally lit state, if the discharge lamp has a high output such as 120 WA'In or more, The heat cutoff filter on the outer circumferential surface of the discharge lamp does not cool the lamp sufficiently, which not only causes the lamp to darken, but also causes the central part of the bulb to sag.
本発明は上記事情に鑑みてなされたもので、放する。The present invention has been made in view of the above circumstances.

沿って複数個設けられている。(1) is a horizontally lit discharge lamp, and the neck portions (3) at both ends of the bulb (2) are supported by holders (not shown). The outer peripheral surface of the valve (2) is surrounded by a heat cutoff filter (4). Further, (5) is a spacer made of a material with low thermal conductivity and formed between the lower surface of the bulb (2) and the heat cutoff filter (4). To explain this embodiment in more detail, lead wires (not shown) are led out from the neck part (3) at both ends of the discharge lamp (1).

and an inlet (8) and an outlet (9) between the inner pipe (6)
A cooling medium such as water is passed through the tube. When the discharge lamp (1) is lit for several tens of hours, the bulb (2) tends to droop if it is a high-output lamp. Valve at this time (2)
The temperature at the center is about 800 to 900°C. Since the spacer (5) is interposed between the lower surface of the bulb (2) and the heat cutoff filter (4), the above-mentioned drooping is prevented. If the thickness of the spacer (5) is appropriately selected and the bulb (2) is brought close to the heat cutoff filter (4), the bulb (2) will be cooled by the filter (4) and overheating will be suppressed.

できるものである。As described in detail above, the present invention includes a spacer made of a material with low thermal conductivity between the heat cutoff filter and the lower surface of the bulb of the discharge lamp, thereby preventing the bulb of the discharge lamp from overheating and drooping. Furthermore, since the means for doing so only requires the interposition of a spacer, it can be manufactured at low cost.
