（産業上の利用分野）
本発明は紫外線の放射を減らしたハロゲン電球に関する
。DETAILED DESCRIPTION OF THE INVENTION OBJECTS OF THE INVENTION Field of Industrial Application The present invention relates to a halogen lamp with reduced ultraviolet radiation.
（従来の技術）
近年、店舗照明において、小形ハロゲン電球に反Ｑ１鏡
を組合わせてなる反射形ハロゲン電球が賞用されるＪ：
うになった。(Prior art) In recent years, reflective halogen light bulbs made by combining small halogen light bulbs with anti-Q1 mirrors have been used for store lighting.
I became angry.
この電球は比較的狭い範囲に強力な光を集中するので、
商品の形状や色彩を鮮明に印象づけることができ、店舗
照明として極めて優れた効果がある。This bulb concentrates intense light in a relatively small area, so
It can give a clear impression of the shape and color of the product, and is extremely effective as store lighting.
そうして、従来の反射形ハロゲン電球は可視光とともに
大量の赤外線を放射するので照射された商品などが高温
になり、女形、退色、脆化なと種々の不都合を生じた。Conventional reflective halogen light bulbs emit a large amount of infrared rays along with visible light, which causes the irradiated products to become hot, causing various problems such as deformation, discoloration, and brittleness.
そこで、最近に至って赤外線放射の少ないハロゲン電球
が開発された。たとえば、コイルフィラメントを封装し
た石英ガラスバルブの内外両面のうち少なくとも一方の
面に赤外線反射膜を設りて、フィラメントから放射され
た光のうち可視光をそのまま外部に放射し、赤外線を反
射してフィラメントに帰還させることによりランプ効率
を向上するとともに赤外線放射を少なくしたハロゲン電
球が開発され、商品などの熱損がなくなった。Therefore, halogen light bulbs that emit less infrared radiation have recently been developed. For example, an infrared reflective film is provided on at least one of the inner and outer surfaces of a quartz glass bulb containing a coiled filament, so that the visible light emitted from the filament is directly radiated to the outside, and the infrared light is reflected. Halogen light bulbs have been developed that improve lamp efficiency and reduce infrared radiation by returning light to the filament, eliminating heat loss in products.

照射物を熱損するおそれがなくなったが、たとえば繊維
品などの退色は依然解決しなかった。(Problems to be Solved by the Invention) Since the above-mentioned conventional halogen bulb emits little infrared radiation, there is no risk of heat loss to the irradiated object, but discoloration of textiles, etc., for example, remains unsolved.
本発明者はこの退色の原因を追究した結果、退色は可視

物の退色を大幅に軽減できることに想到し、短波長紫外
線を放射しないハロゲン電球を提供することを目的とし
、本発明を完成した。As a result of investigating the cause of this discoloration, the present inventor discovered that discoloration is caused by irradiation with visible light and is promoted by the synergistic effect of short wavelength ultraviolet rays present in minute amounts. Therefore, we came up with the idea that by removing the small amount of short wavelength ultraviolet rays contained in the light emitted from a halogen bulb, we can significantly reduce the fading of the irradiated objects, such as products, and provide a halogen bulb that does not emit short wavelength ultraviolet rays. With this aim, the present invention was completed.

外線吸収膜によって吸収除去するものである。(Means for Solving the Problems) The present invention was made in order to reduce the irradiation of short wavelength ultraviolet rays in a halogen light bulb in which a filament is sealed in a quartz glass bulb. By forming an ultraviolet absorbing film that absorbs ultraviolet rays with a wavelength of 350 nm or less on at least one surface, the ultraviolet absorbing film absorbs and removes a small amount of short wavelength ultraviolet rays contained in the light emitted from the filament.

ゲン電球の光を照射しても、この光の退色作用は短波長
紫外線による促進作用がないので、従来のハロゲン電球
による照射に比較してはるかに少ない。(Function) Because the filament temperature of halogen bulbs is extremely high, the emitted light contains a small amount of short-wavelength ultraviolet rays. Although this short-wavelength ultraviolet ray passes well through the quartz glass bulb, it is absorbed and removed by the ultraviolet absorbing film and is hardly emitted to the outside. Therefore, even when irradiated with light from this halogen bulb, the fading effect of this light is far less than when irradiated with a conventional halogen bulb, since short-wavelength ultraviolet rays do not accelerate the effect.

の紫外線吸収膜（２）の光透過率は第２図に示すとおり
、可視光を良く透過し、紫外線の透過率は極めて低い。The ultraviolet absorbing film (2) is a thin film made of, for example, anatase titanium oxide crystal, and has a thickness of approximately 1200 mm. As shown in FIG. 2, the ultraviolet absorbing film (2) has a good transmittance of visible light and an extremely low transmittance of ultraviolet light.
特に波長３５０ｎｍ以下の短波長紫外線の透過率はほと
んどＯに近い。In particular, the transmittance of short wavelength ultraviolet rays having a wavelength of 350 nm or less is almost O.

よい。Various methods can be considered to obtain this ultraviolet absorbing film. For example, titanium oxide may be vacuum-deposited on the outer surface of a sealed light bulb. It is immersed in an organic solvent solution of a titanium compound and pulled up.
After drying, the film may be fired to transform it into an anatapi-type titanium oxide film.

に放射されることがない。When the halogen light bulb of this embodiment is turned on, the filament 0 is heated to a high temperature and emits strong light. Most of this light is visible light and infrared light, but small amounts of ultraviolet light of various wavelengths are also emitted. In this way, ultraviolet rays, particularly short wavelength ultraviolet rays with a wavelength of 350 nm or less, pass through the quartz glass bulb (2), but almost/all of it is absorbed by the ultraviolet absorbing film (2) and is not emitted to the outside.

品などは長期照射によっても退色が格段に少ない。Therefore, when the halogen bulb of this embodiment is used alone or in combination with a reflector, it is possible to irradiate an object with intense light that contains almost no ultraviolet rays. Therefore, colored objects such as textiles, paintings, and crafts that are illuminated by such halogen bulbs or lighting equipment that combines the bulbs with reflectors are much less likely to fade even after long-term irradiation.

電球の発光効率を著しく向上できる。In the above embodiments, the ultraviolet absorbing film was formed on the outer surface of the bulb, but the present invention is not limited thereto, and it may be formed on the inner surface of the bulb, or may be formed on both the inner and outer surfaces of the bulb. Further, in the present invention, a combination of an ultraviolet absorbing film and an infrared reflecting film may be used, for example, an infrared reflecting film may be formed on the inner surface of the bulb and an ultraviolet absorbing film may be formed on the outer surface of the bulb. In this case, short wavelength ultraviolet rays and infrared rays in the emitted light can be removed together, and the luminous efficiency of the light bulb can be significantly improved.

１テるには膜厚を１０００〜１２００人にすればにい。Note that the peak of the transmission wavelength range of a titanium oxide thin film changes slightly depending on the film thickness, so the film thickness can be selected appropriately depending on the purpose. For example, to achieve good transmittance in the entire visible range, the film thickness must be If it's 1000 to 1200 people, it's good.
ざらに、紫外線吸収膜は酸化第２錫（Ｓｎ０２）や酸化
アンチモン（Ｓｂ０２）などで構成しても同様な効果が
ある。Generally speaking, the same effect can be obtained even if the ultraviolet absorbing film is made of stannic oxide (Sn02), antimony oxide (Sb02), or the like.
そうして、適用すべきハロゲン電球の細部の構造には制
限がない。Thus, there are no restrictions on the detailed structure of the halogen bulb to be applied.

It can absorb and remove short wavelength ultraviolet rays from the light emitted from the filament.
Since the effect of promoting fading due to ultraviolet rays has been eliminated, fading due to visible light has been significantly reduced.
