Further, since the temperature of the fiber fixing member (6) is also reduced by the air flow (8), the temperature of the fiber (7) can be reduced more effectively. Therefore, it is possible to operate the lamp (1) having a high output for a longer time without surely deteriorating the fiber (7).

Further, as shown in FIGS. 3 and 4, the fiber fixing member (6) is provided with a fin (10) having a structure in which a temperature difference is intentionally generated between the base end and the tip thereof.

Further, since the temperature of the fiber fixing member (6) is also reduced by the air flow (8), the temperature of the fiber (7) can be reduced more effectively. Therefore, it is possible to operate the lamp (1) having a high output for a longer time without surely deteriorating the fiber (7).

Further, as shown in FIGS. 18 to 21,
When the fiber fixing member (6) is formed even inside the housing (4) in which the lamp (1) is housed, the temperature of the fiber (7) and the fiber fixing member (6) is increased. In addition to reducing the temperature, the temperature can be reduced more effectively by directly blowing air to the incident end face of the fiber (7). Therefore,

Therefore, it is possible to operate the lamp (1) having a high output for a longer period of time without further deteriorating the fiber (7).

As shown in FIGS. 28 and 29,
When the fiber (7) is fixed with the screw (14), the temperature of the fiber (7) and the fiber fixing member (6) can be reduced, and the fiber (7) is firmly fixed. In addition to that, the position of the incident end of the fiber (7) can be finely adjusted. Moreover, the presence of the screw (14) makes it possible to reduce the influence of the deviation of the focusing position due to the variation of the lamp (1) and the reflecting mirror (2). Therefore, it is possible to operate the lamp (1) having a high output for a longer period of time without further deteriorating the fiber (7).
