を設けるようにしたものがある。A light irradiation device such as an ultraviolet irradiation device forcibly cools the reflector using a cooling means using an airflow to prevent the reflector from being overheated by the heat of the discharge lamp. Therefore, per 1 cm of arc length containing a halide, the power is 90W, that is, 9
In a discharge lamp with a lamp input of 0 W/cJn, especially 40 to 90 W/cm, the discharge lamp is installed in the air flow path, so the discharge lamp cannot be cooled uniformly, and the coldest part There was a problem in that the temperature became too low and the vapor pressure in the bulb of the discharge lamp decreased, making it impossible to obtain desired lamp characteristics and resulting in a decrease in output. As a countermeasure for this, for example,
As shown in Japanese Patent No. 46215, there is a discharge lamp (4) in which a water cooling jacket is provided on the outer peripheral surface of the discharge lamp (4) to allow water to flow between the double tubes.
しかして、このように２重管式で、かつ水を通流するも
のでは、構造が複雑化し、高価となるのを免れない。However, such a double-tube system that allows water to flow through it inevitably has a complicated structure and is expensive.

is a reflector, and the outer surface of this reflector (1) is forcibly cooled by cooling means (not shown). (4) is a discharge lamp with a lamp input of 90 W/cm or less installed opposite to the reflector (1) in the flow path of the ventilation flow (8); (5) is a cylindrical translucent ventilation flow blocking filter; An air layer (6) is interposed between the discharge lamp and the outer peripheral surface of the discharge lamp (4) to surround the discharge lamp (4).

In the flow path of this ventilation flow (3), an air layer (6) is interposed between the discharge lamp (4) installed opposite to the reflector (1),
By providing a cylindrical translucent ventilation flow cutoff filter (5), the discharge lamp (4) is not exposed to the ventilation flow (3) and is appropriately kept warm by the filter (5), so that the coldest part The filter (
The heat emitted from 5) is carried away by the ventilation flow (8), thereby preventing overheating of the reflector ([). Note that this is different from the case where the discharge lamp (4) is simply provided with a cylindrical body on the outer peripheral surface, and the discharge lamp (4) is provided inside a water cooling jacket that allows water to flow between the double tubes. It has a simple structure and can be manufactured at low cost.

) has electrodes (8) at both ends within the pulp (7), and lead wires (not shown) are led out from neck portions (9) at both ends. The reflector (1) has a parabolic reflecting surface ai. The reflector (1) is divided into two parts at the center, and both ends are connected by a connector I, with a gap provided in the center to form a ventilation path υ. As a result, a ventilation flow in the direction of the arrow (3) or a ventilation flow in the opposite direction is generated by a cooling means such as an exhaust device. The filter (5) is made of stone-filled glass and has a cylindrical shape. Moreover, as a light irradiation device, only an ultraviolet irradiation device is dangerous, and it may be used for illumination. In this case, the filter (5) may be made of ordinary glass.

In this system, a cylindrical translucent ventilation flow cut-off filter was provided that surrounded the discharge lamp with an air layer interposed between it and the outer peripheral surface of the discharge lamp, so that the discharge lamp was cooled unevenly by the ventilation flow. The lamp characteristics do not change and the lamp output does not decrease as a result, and the structure is simple and can be manufactured at low cost.
