反射性の塗膜を設けるようにしている。(Prior Art) In a lighting equipment equipped with a reflector having a rotating quadratic curved reflecting surface, if the reflected light of the lamp is seen from the reflecting surface near the light emitting opening of the reflector, it will cause a sense of glare. A separate black baffle is placed over the opening to prevent glare. In some cases, a glare prevention part is integrated into the light emitting opening of the reflector, but in this case, when forming the glare prevention part, that part is masked. A non-reflective coating is applied to the anti-glare part in a separate process from the main part.

を感じない反射光となる。(Function) The reflective film is formed on the reflector by vapor deposition, but in this case, the direction of vapor deposition by the vapor deposition device is directed mainly toward the reflective surface of the first reflector, and the first reflector is It is possible to perform vapor deposition in a focused manner, and in this case, if the reflective surface of the second reflector is left as it is without masking, the thickness of the reflective film on this surface can be reduced as a result. In general, as the film thickness becomes thinner, the wavelength of the reflected light reflected by this type of reflective film shifts to a shorter wavelength ([1], so the light reflected by the second reflector becomes a blue-violet, etc. The reflected light is glare-free.

It is installed opposite to the container 2. Further, reference numeral 12 denotes a support for supporting the reflector 2 attached to the top plate of the main body 1, and a mounting hole 13 provided in the reflector 2 is inserted into the support
The reflector 2 is attached to the support 12 by engaging the projections 14 provided thereon. Generally speaking, reference numeral 15 denotes a frame body, which is not shown, but is attached to the main body by a well-known means such as a spring.

／２〜１／８の膜厚とするのがよい。The reflective films 8 and 9 are formed on the reflector by vapor deposition. The vapor deposition direction of the vapor deposition apparatus (not shown) is set to the first
The light should mainly face the reflector 5. A substance with a high optical refractive index, such as zinc oxide (ZnS), and a substance with a low optical refractive index, such as magnesium fluoride (MCIF2), are alternately and intensively deposited in multiple layers on the first reflector 5.
The multilayer optical interference film is also deposited on the second reflector 7, but the deposition direction of the second reflector 7 by the vapor deposition apparatus is different from that of the first reflector 5. Therefore, the thickness of this reflective film 9 is thinner than that of the first reflector 5. The thickness of the reflective film 8 of the first reflector 5 is 5 to 1
5μ, and the thickness of the reflective film 9 of the second reflector 7 is 1.25 to 5μ.
μ is appropriate, and the reflective film 9 is 1 with respect to the reflective film 8.
It is preferable to set the film thickness to 1/2 to 1/8.
つぎに上記実施例の作用について説明する。薄膜設計は
、一般にｎＸＤ＝λ／４から、ｎ（屈折率〉とＤ（膜厚

As the wavelength becomes thinner, the wavelength shifts to the shorter wavelength side. Therefore, the second reflector 7 can emit reflected light such as bluish-violet light that does not cause glare.

反射膜８に対する相対的な膜厚を調整するものとする。The reflector 9 can be made of metal such as aluminum, but may also be made of plastic. When changing the film thickness of the reflective films 8 and 9 with respect to the second reflectors 5 and 7, the vapor deposition apparatus changes the film thickness of the reflective film 8 with respect to the first reflector 5 to that of the second reflector. The thickness of the reflective film 9 of the second reflector 7 increases as the vapor deposition device is gradually moved away from the reflective film 9 of the second reflector 7. Reflective film 8 of second reflector 5, 7
9 will remain almost unchanged. Therefore, by appropriately adjusting the position of the vapor deposition apparatus with respect to the first reflector 5, the relative film thickness of the reflective film 9 of the second reflector 7 with respect to the reflective film 8 of the first reflector 5 can be adjusted. shall be taken as a thing.

のである。The second reflector 7 is approximately parallel to the optical axis of the first reflector 5, but even if it is formed into a somewhat curved surface or slightly inclined to either the inside or the outside, it may be approximately parallel to the optical axis of the first reflector 5. Since the effects of the present invention can be obtained in the same manner, it is included within the scope of the present invention.

た反射器を容易、安価に製作できるものである。As described in detail above, the reflector in the lighting device of the present invention has a rotating quadratic curved surface, and the first reflector has an infrared transmitting and visible light reflecting film formed of a multilayer interference film formed on this surface. and a first reflector formed integrally with the front opening of the reflector, having a surface substantially parallel to the optical axis of the first reflector, and formed of a multilayer optical interference film on this surface. and a second reflector formed with a reflective film having a thickness thinner than that of the reflective film, there is no need to provide a separate anti-glare body at the front opening of the reflector, and the reflective film When forming a reflective film on the first reflector, the second reflector for glare prevention is also coated with a glare-free or low-glare reflective film in the same process. Since a film can be formed, a reflector that prevents glare near the light emitting aperture can be manufactured easily and inexpensively.
