In order to stably evaporate the luminescent substance, the outside air and the discharge lamp are shut off, and the entire discharge lamp is hermetically arranged in a translucent outer tube in order to prevent the arc tube from being cooled beyond the set conditions. A double tube lamp structure is known.

このようなニ重管型ランプは、放射される光の方向を制御するために、反射鏡に組み込まれて放電ランプ装置として利用されている。
このような技術は、特許文献１（特開２００２−１１０１００号）に記載されている。 Such a double tube lamp is incorporated in a reflecting mirror and used as a discharge lamp device in order to control the direction of emitted light.

一方、放電ランプは、始動性を改善するために、ランプ始動時に、放電空間に紫外線を照射する技術は知られている。
紫外線を放射するために、放電ランプと別に紫外線放射補助光源を用いている。このような技術は、特許文献２（特開２００２−１５１００６号）に記載されている。
特許文献２では、放電ランプと紫外線放射補助光源を外管内に密閉配置した二重管型ランプ構造が記載されている。 On the other hand, in order to improve the startability of the discharge lamp, a technique for irradiating the discharge space with ultraviolet rays when starting the lamp is known.
In order to radiate ultraviolet rays, an ultraviolet radiation auxiliary light source is used separately from the discharge lamp. Such a technique is described in Patent Document 2 (Japanese Patent Laid-Open No. 2002-151006).
Patent Document 2 describes a double tube lamp structure in which a discharge lamp and an ultraviolet radiation auxiliary light source are hermetically arranged in an outer tube.

Reference numeral 8 denotes a front glass that closes the front opening 51.

このような放電ランプ装置では、紫外線放射補助光源２の配置位置は、特に、考慮されておらず、単に、紫外線放射補助光源２は、外管３内であって、放電ランプ１の近傍に配置されていた。   In such a discharge lamp device, the arrangement position of the ultraviolet radiation auxiliary light source 2 is not particularly considered, and the ultraviolet radiation auxiliary light source 2 is simply disposed in the outer tube 3 and in the vicinity of the discharge lamp 1. It had been.

そして、紫外線放射補助光源２の一部が、反射鏡５の首部開口５２側に位置する電極１１の先端と首部開口５２の開口縁５ａを結ぶ仮想線Ｌに対して、反射鏡５の前方開口５１側に突出した位置になる場合があり、この場合、放電ランプ１から放射され、本来、反射鏡５の反射面に照射される光が紫外線放射補助光源２の一部によって遮光され、照射面での配光分布が乱れるという問題があった。
特開２００２−１１０１００号公報 特開２００２−１５１００６号公報 Then, a part of the ultraviolet radiation auxiliary light source 2 has a front opening of the reflecting mirror 5 with respect to a virtual line L connecting the tip of the electrode 11 positioned on the neck opening 52 side of the reflecting mirror 5 and the opening edge 5a of the neck opening 52. In this case, the light emitted from the discharge lamp 1 and originally irradiated on the reflecting surface of the reflecting mirror 5 is shielded by a part of the ultraviolet radiation auxiliary light source 2, and the irradiation surface There was a problem that the distribution of light distribution was disturbed.
