寿命途中で標識が劣化しては困ることになる。[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention prevents deterioration of signs placed on the outer surface of a discharge lamp due to ultraviolet rays. (Prior Art) In general, in various discharge lamps such as fluorescent lamps and high-pressure discharge lamps, the manufacturer's name, product name, etc. are written on easily visible parts of the outer surface, such as the outer surface of the bulb, the surface of the base, or the outer surface of the lamp support.
It is marked with vsm to indicate the rating. iRr like this
For example, a is printed on the outer surface of the bulb with an ink made by mixing an organic dye with a silicone resin, or is made by mixing an inorganic dye with a film material such as nitrocellulose or phthalic acid resin on the outer surface of the Yuria resin cap. Often crude types are used, such as labels printed with ink or labels printed on a plastic sheet with the various inks mentioned above and attached to a polycarbonate resin lamp support. (Problems to be Solved by the Invention) Generally, discharge lamps generate ultraviolet rays during discharge, and a portion of the ultraviolet rays pass through the bulb and leak to the outside. On the other hand, J
Some materials are easily degraded by ultraviolet light.
For example, organic dyes, nitrocellulose, phthalic acid resins, and vinyl chloride resins have the property of fading or becoming brittle when exposed to ultraviolet light. Therefore, if a label is applied to the outer surface of the bulb using, for example, the above-mentioned material, the S* will deteriorate due to the leaked ultraviolet rays that have passed through the bulb. Furthermore, if a mark is made of the above-mentioned material on the outer surface of the cap, leaked ultraviolet rays that have passed through the bulb are reflected by the reflector and enter the mark, causing it to discolor or become brittle. Moreover, discharge lamps generally have a long lifespan, so
It would be a problem if the sign deteriorated during its lifespan.
そこで、本発明の課題は外面に耐紫外線性に劣る標識を
施した放電灯において、放電灯が寿命末期に到るまで標
識が劣化しないようにすることである。Therefore, an object of the present invention is to prevent the marking from deteriorating until the discharge lamp reaches the end of its life in a discharge lamp whose outer surface is marked with a marking having poor ultraviolet resistance.

のである。(Means for Solving Problem 11) The present invention provides a discharge lamp with the above-mentioned markings, by shielding the direction of incidence of ultraviolet rays from the markings with an ultraviolet blocking film.
This prevents deterioration by preventing ultraviolet rays from entering the sign.

Additionally, if the surface of the sign is covered with a coating, vapor deposited, or baked film made of Saran, polyester, nylon, ethyl cellulose, etc., it is possible to block the ultraviolet rays reflected from the reflector, while also allowing the UV rays to pass through these films. You can see the signs without harming the display effect. Therefore, an appropriate ultraviolet blocking film may be selected and used depending on the portion of the discharge lamp that is marked.

明なので表示効果を害しない。When this high-pressure mercury lamp is turned on, a portion of the ultraviolet light passes through the neck portion (13) of the outer tube, leaks out, and enters the first ultraviolet blocking film (2) from the inside. However, since this first ultraviolet blocking film is made of metal, it has a high ultraviolet blocking property and does not allow any ultraviolet light to pass through. Also, some of the ultraviolet rays are absorbed by the outer tube (
11), leaks out, is reflected by a reflection plate (not shown), and enters the second ultraviolet blocking film 0) from the outside. but,
Since the second ultraviolet blocking film (f) is made of nylon, it blocks ultraviolet rays and prevents the sign (3) from being deteriorated by ultraviolet rays. Furthermore, since the second ultraviolet blocking film (2) is transparent, it does not impair the display effect.

の物質が無機物たると有機物たるとを問わない。Although the above-mentioned embodiments have been described with respect to fluorescent lamps and high-pressure mercury lamps, the present invention is not limited thereto, and can be applied to all discharge lamps that leak ultraviolet rays. Anywhere is fine. Furthermore, the present invention is effective as long as at least one of the dye and the film-forming substance is easily degraded by ultraviolet rays, and it does not matter whether these substances are inorganic or organic.

とがない。In this way, the discharge lamp of the present invention has a sign with poor UV resistance on its outer surface, but since the direction of UV light incidence on the sign is blocked by the ultraviolet blocking film, there is no risk of the sign deteriorating due to ultraviolet rays, and it can be used for a long time. However, the display function will not be impaired.
