Description
【発明の詳細な説明】 ［産業上の利用分野］ 本発明は、光源の効率を高めたランプに関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a lamp with improved light source efficiency.

光源の効率を高めていた。[Prior art] Fig. 3 shows an example of a conventional lamp, where 21 is a white heat-retaining film;
22 is an arc tube, and 24 is a reflector. Conventionally, the reflector 24 condenses and collimates light to increase light output. Furthermore, the efficiency of the light source was increased by attaching a white heat-retaining film 21 to the arc tube 22.
［発明が解決しようとする課題及び目的］しかし、前述

乱された光を集光・平行化し、光源の効率を高めた装置
を提供するものである。[Problems and objects to be solved by the invention] However, in the former technique, nothing is done regarding the light scattered in the forward direction, and in the latter, the primary purpose is to uniformize the temperature of the wall of the arc tube. The problem is that the reflectance is not good enough to increase the amount of light. SUMMARY OF THE INVENTION The present invention is intended to solve these problems, and its purpose is to provide a device that condenses and collimates the light scattered in the forward direction, thereby increasing the efficiency of the light source.
［課題を解決するための手段］
本発明のランプは、照明装置や投射器等でリフレクタ−
・光源より構成されるランプにおいて、前記光源より発
光されかつ前記リフレクター方向に進まず直接前方向に
散乱されてしまった光を前記リフレクター方向に反射す
る反射装置を備えてることを特徴とする。[Means for Solving the Problems] The lamp of the present invention has a reflector in a lighting device, a projector, etc.
- A lamp composed of a light source is characterized in that it is equipped with a reflection device that reflects light emitted from the light source and scattered directly forward without proceeding toward the reflector, toward the reflector.
［実施例］ 本発明の実施例を図面にもとづいて説明する。[Example] Embodiments of the present invention will be described based on the drawings.
第１図は実施例１であり、ランプの断面図である。FIG. 1 shows Example 1 and is a sectional view of the lamp.
１は反射ミラー、２は発光管、３は封止部、４はリフレ
クタ−である。1 is a reflecting mirror, 2 is an arc tube, 3 is a sealing part, and 4 is a reflector.
第１図において、封止部３に反射ミラー１を取り付ける
１発光管２より発された前方向の光が反射ミラー１で反
射されリフレクタ−４に進む、ミラーの曲面は、リフレ
クタ−４で反射される光が平行になるように設定する。In Fig. 1, a reflecting mirror 1 is attached to a sealing part 3. 1 Light emitted from the arc tube 2 in the forward direction is reflected by the reflecting mirror 1 and proceeds to a reflector 4. The curved surface of the mirror is reflected by the reflector 4. Set the light so that it is parallel.
このようにすることによって前方向に散乱した光をリフ
レクタ−４方向に反射させ、集光・平行化する光量の増
大をさせる。このようにして、光源の効率を高める。ま
た、垂直点灯時には空気の流れが発光管２全体に均一に
流れるため光源の温度の均一化がはかれる。By doing this, the light scattered in the forward direction is reflected in the direction of the reflector 4, thereby increasing the amount of light that is condensed and collimated. In this way, the efficiency of the light source is increased. Furthermore, during vertical lighting, the air flows uniformly throughout the arc tube 2, so that the temperature of the light source can be made uniform.
これによって発光量や色を安定させることができる。This makes it possible to stabilize the amount of light emitted and the color.

12 is a metal film, 12 is an arc tube, and 14 is a reflector.
第２図において発光管１２の前方向の部分に反射性の良

乱を防止し、リフレクタ−１４への光量の増大させる。In FIG. 2, a highly reflective metal film 11 is applied to the front portion of the arc tube 12. In this way, forward scattering is prevented and the amount of light directed to the reflector 14 is increased.
このようにすることによって光源の効率を高める。また
、この場合には発光管１２の管壁の温度の均一にも役立
ち、光源の安定にもなっている。This increases the efficiency of the light source. Further, in this case, it helps to uniform the temperature of the tube wall of the arc tube 12, and also stabilizes the light source.
