や光束維持率が悪くなる欠点がある。2. Description of the Related Art A rapid start type fluorescent lamp generally has a structure in which a transparent conductive film mainly composed of tin oxide is formed on the inner surface of a glass tube, and a phosphor film is formed thereon. The transparent conductive film is called a NESA film and assists in starting the fluorescent lamp when it is turned on. When such a fluorescent lamp is lit for a long time, mercury that has penetrated into the transparent conductive coating from between the phosphor particles of the fluorescent coating chemically reacts with tin oxide of the transparent conductive coating, and the transparent conductive coating turns yellow. However, there is a drawback that the appearance and luminous flux maintenance rate of the fluorescent lamp are deteriorated.

蛍光ランプは、次のように製造されている。As a solution to the above-mentioned drawbacks, an alumina coating is formed on the transparent conductive coating formed on the inner surface of the glass tube as a protective film for preventing mercury from coming into contact with the transparent conductive coating. There is a rapid start type fluorescent lamp in which a phosphor coating is formed on an alumina coating. This fluorescent lamp is manufactured as follows.

懸濁液が使用される。First, a transparent conductive film mainly containing tin oxide is formed on the inner surface of the glass tube by a spray method or the like. Next, a suspension containing alumina (aluminum trioxide) powder as a main component is applied on the transparent conductive film and dried to form an alumina film. Next, a phosphor suspension is applied on the dried alumina coating, dried, and then baked together with the alumina coating to form a phosphor coating. As the phosphor suspension for forming the phosphor coating, a suspension containing phosphor powder, a binder and an organic solvent is used.

Rapid start type fluorescent lamp is manufactured. The rapid start type fluorescent lamp manufactured in this way has a difference in the coating amount of the alumina coating or the phosphor coating, but the alumina coating prevents discoloration of the transparent conductive coating, and the appearance of the fluorescent lamp and the luminous flux maintenance rate. I know that will improve.

We have made many prototypes of rapid start fluorescent lamps in which the phosphor coating is formed on the alumina coating in the glass tube with a water-based phosphor suspension using a water-soluble binder. A water-based phosphor suspension is a suspension containing phosphor powder, a water-soluble binder such as polyethylene oxide, and water (solvent). The phosphor coating is formed by pouring it into a glass tube, drying it, and baking it. It is formed. It has been known that an aqueous suspension using such a water-soluble binder is low in cost, waste liquid can be easily treated at low cost, and fluorescent lamps can be mass-produced at low cost.

Even in the same appropriate range as above, the problem that the appearance of the fluorescent lamp deteriorates due to the rough coating of the phosphor coating skin,
It was found that a new problem of discoloration of the transparent conductive coating occurs. Experimental data for such a problem occurrence will be described with reference to the graph of FIG.

で商品価値を持つ。FIG. 2 is a graph of the experimental data of the amount of alumina coating formed on the transparent conductive coating on the inner surface of the glass tube and the total luminous flux [lm] of the fluorescent lamp. The amount of fluorescent coating is 4.0 ×. It is unified to an appropriate amount of about 10 -3 g / cm 2 .
According to this experimental data, 1 cm 2 on the transparent conductive film
The maximum total luminous flux is about 2.6 × 10 -5 g / cm 2 of alumina coating per unit, and even if the amount of adhesion is less than 2.6 × 10 -5 g / cm 2 The luminous flux is reduced. In a rapid start type fluorescent lamp in which a phosphor coating is formed with a conventional organic suspension, the amount of alumina coating deposited is within the range of 8.7 × 10 -6 g / cm 2 to 5.2 × 10 -5 g / cm 2 . If it is, this fluorescent lamp has proper appearance and total luminous flux and has commercial value.

When a phosphor coating is formed on the alumina coating with an adhesion amount in the range of g / cm 2 with an aqueous suspension, the larger the adhesion amount of the alumina coating, the rougher the coated surface of the phosphor coating becomes, and Appearance deteriorates. It has been known that the deterioration of the coating surface of the phosphor coating occurs remarkably when the amount of the alumina coating attached exceeds 2.6 × 10 −5 g / cm 2 .
