招く欠点がある。(Problems to be Solved by the Invention) However, when there is a pair of light emitting sections, it is very difficult to select where on the parabolic reflector the pair of light emitting sections should be positioned to obtain high efficiency. For example, if the focal point of the reflector is located between a pair of light emitting parts, there is a risk that the light emitting part on the top side of the reflector may come close to or hit the surface of the top of the reflector. Therefore, by increasing the focal length and increasing the distance between the focal point and the top surface of the reflector, this will prevent the light emitting sections from coming close to the top surface even if the center of the pair of light emitting sections is positioned at the focal point. It becomes possible to However, this method has the drawback of increasing the size of the reflecting plate, that is, increasing the size of the device.

きる。(Function) Since the positional relationship between the pair of light-emitting parts and the reflector is as described above, even if the focal length of the reflector is short, the lamp light-emitting part will not be close to the top of the reflector, and therefore the lamp will not be close to the top of the reflector. Can be made smaller.

略焦点位置に設けている。(Example) Next, details of the present invention will be explained with reference to the drawings. 1 is a parabolic reflector, and 2 is a pair of rod-shaped light emitting parts arranged side by side along the optical axis of this reflector 1. This pair of light emitting parts 2 are
The top side of the reflector 1 of these light emitting parts 2 is provided at approximately the focal point position of the reflector 1.
上記実施例についてざらに詳述すると、反射体１の焦点
距離は、たとえばＦ＝３０ｍｍに設定されている。To explain the above embodiment in detail, the focal length of the reflector 1 is set to, for example, F=30 mm.

たところ、反射体１の開口半径 は７５ｍｍであった。Next, the operation of the above embodiment will be explained. As a pair of light emitting parts, for example, a compact fluorescent pump FPL36E
The light distribution when using X-N (tube diameter 20 mm, length 410 mm) is as shown in the figure, and the reflected light is directed in a predetermined direction without being obstructed by the light emitting part 2, increasing the reflection efficiency. did it. In this case, when the beam angle was set to 15 degrees, the aperture radius of the reflector 1 was 75 mm.

As the position of the pair of light emitting parts 1 moves from the focal point to the top side of the reflector 1, the aperture radius becomes larger. For example, if the entire light emitting part 2 on the non-top side of the reflector 1 moves from the focal point to the top side of the reflector 1. , to obtain the same reflection efficiency as the present invention, the aperture radius is 14
2 mm, and the reflector 1 becomes even larger.
