Abstract

PURPOSE:To improve optical output during a lamp is lighting with a high frequency power supply by setting the external bulb length and internal bulb length to the particular values and by filling the inside with the predetermined amount of argon gas in a fluorescent lamp of double-bulb structure comprising the U- shaped internal bulb forming the discharge path. CONSTITUTION:A compact size fluorescent lamp is formed with such a double- bulb structure as comprising an external bulb 1 forming the sealed space and the U-shaped internal bulbs 2 which are sealed within the external bulb 1 and form the discharge paths. In case of lighting such fluorescent lamp with a high frequency power supply, the external bulb length L is set in the range of 75mm.<=L <=80mm. and the internal bulb length is set in the range of 58mm.<=l<=65mm. and simultaneously the sealed space is filled with the argon gas in the pressure of 3.5Torr. Accordingly, a high optical output can be obtained by setting the external bulb length to such a value not deteriorating a compact lamp size and the internal bulb length l to a value which minimizes a lamp power required for obtaining the same optical power.

Next, let's talk about assembly. First, both open ends of each inner tube 2 are fitted into the counterbore portions 6 of the inner tube insertion holes 7a to 7f, and then attached to the spacer B with an adhesive such as a heat-curable heat-resistant inorganic adhesive or glass frit. Fix airtightly. This airtight fixation does not necessarily require airtightness as long as the gap created between the outer wall of the inner tube 2 and the counterbore 6 of the spacer 6 is made small. Next, the spacer 3 integrated with the inner tube 2 in this way is attached to the stem 4, and both electrodes 16, 16 provided on the stem 4 and the encapsulated wire 12 for fixing the spacer are attached to the stem 4.
They are arranged so as to correspond to the inner tube insertion hole 7C17f provided in the spacer 6 and the enclosing wire insertion groove 10, respectively. The spacer 6 and the stem 4 are fixed by bending the spacer fixing encapsulation wire 12 inward toward the upper surface of the spacer B. Through this step, i&11 and each inner tube 2 are connected in series to form one discharge path. Stem 4 of spacer 6
Fixing to the cap does not necessarily require airtightness if the cap is made small. After the open end of the outer bulb 1 and the outer periphery of the stem 4 are hermetically sealed, the lamp part A is completed by performing the usual electrode material activation treatment, exhausting, and filling with discharge gas and mercury from the exhaust pipe 14. do.

Therefore, such a fluorescent lamp has a power source for drawing, that is, 50~
60■zo) It is designed to efficiently light up at the operating frequency. To explain it with a specific example, from the viewpoint of ambient temperature characteristics and starting performance, argon gas is used as a discharge gas in the pipe. The lamp size is 75 mm and the diameter of the outer tube is 60 mm, so that the lamp size is comparable to a 60 watt incandescent bulb, and the light output is 8007 m, which is equivalent to a 60 watt incandescent bulb. In order to secure this number, we have hired 55 Uchikancho l.

(Disclosure of the Invention) The present invention will be explained below. FIG. 6 is a front view of a lamp section (corresponding to the lamp mA shown in FIG. 1) for explaining the present invention. The structure is the same as that of the lamp section A of the fluorescent lamp, so the explanation will be omitted by giving the same reference numerals to the same parts.

上述のように 外當長し≦80脳 でなければならない。
First of all, in order not to spoil the compact size of the lamp,
As mentioned above, the external length must be ≦80 brains.

ランプを試作し、点灯周波数約5QKH。
Under these conditions, we prototyped a lamp in which the outer tube length and the inner tube length l were greatly varied, and the lighting frequency was approximately 5QKH.

Figure 4 shows the results of measurements taken with the lights on. In addition, in the same figure, the horizontal axis is the lamp power [W], and the vertical axis is the light output C1m.
"J", and the numbers in the figure, for example 75150, indicate that the outer tube length is 75 heads and the inner tube length l is 5011.

As is clear from Figure 3, the foreign currency length and the inner pipe length 1'-)
As the difference decreases, the ratio of increase in light output to increase in lamp power decreases. This is because as the temperature of the coldest part of the lamp increases, the amount of evaporation of mercury sealed in the tube increases, and ultraviolet photons are lost due to self-absorption of mercury.

In addition, from FIG. 3, in the case of lFf+- Naikancho, the coldest wire temperature of the pigeon lamp with a long outer tube length is lower, so the loss due to the above self-absorption is reduced, and the light output is increased. i
It can be seen that in order to secure a light output of o o o j'm, the outer pipe length needs to be 75 or more. Therefore, the length of the outer tube must be 75g1g≦L≦80M.
