When attaching or detaching the fluorescent lamp of this embodiment to a lighting fixture, the bulbs 11, 11 may be held. At this time, since the lamp body 1 is small, both the bulbs 11, 11 are held at the same time, and therefore a compressive pressure is generated in the direction of pressing the bulbs 11, 11 into contact with each other.
However, since the silicone rubber 2 having a rubber hardness of 40 or more is interposed between the two valves 11, 11, the compressive pressure applied to both the valves 11, 11 is carried by the rubber 2, and the intermediate bending portion 13, hardly any bending stress is generated. Moreover, glass is weak against bending stress but very strong against compressive stress.
Although the intermediate bent portion 13 is blown out and its mechanical strength is reduced, it can withstand considerably strong compressive pressure and will not be damaged. Furthermore, since the silicone rubber 2 is translucent, there is little feeling of foreign matter even when the lamp is turned on, and the appearance is not impaired. Furthermore, since the silicone rubber 2 has high heat resistance, this fluorescent lamp will not become brittle or discolored even when used in a glove, and can withstand long-term lighting, for example, 6000 hours.

Next, in the above-mentioned three examples, four kinds of test specimens were prepared with the rubber hardness of the silicone rubber 2 being 20, 40, 60, and 80, and the valve tip parts 16, 1
A compressive pressure was applied between 6 and 6, and the pressing force when the intermediate bent portion 13 was broken was investigated. The results are shown in FIG. The figure shows rubber hardness on the horizontal axis and compressive strength in Kgf on the vertical axis, with curve I (-○
-) is the above-mentioned Example 1, the curve (-△-) is the above-mentioned Example 2, and the curve (-x-) is the above-mentioned Example 3.
The correlation between each is shown. From this figure, the rubber hardness is
It can be seen that when the value is 40 or more, the compressive strength is extremely high.
The reason for this is that when the rubber hardness is low, elastic deformation is too large to support compressive force, and bending stress is generated in the intermediate bent portion 13. Furthermore, rubber hardness that is too high beyond what is normally called rubber cannot absorb the thermal deformation of the bulb that occurs when the lamp blinks, and this may cause strain on the bent portion and cause damage. For this reason, in the present invention, rubber is limited to "rubber with a rubber hardness of 40 or higher." Therefore, silicone rubber was used in the above embodiments because silicone rubber is colorless and translucent, has high heat resistance and weather resistance, and has a suitable viscosity and is easy to inject. However, in the present invention, other rubbers such as synthetic rubbers may be used, as long as they are translucent, have a rubber hardness of 40 or more, and can withstand the lamp temperature. Furthermore, if minute air bubbles are dispersed in the rubber, it will exhibit light scattering properties, further improving the appearance. Furthermore, the tip of the valve where the rubber should be interposed is the area that is hidden in the hand when the bulb is held, and is usually about 5 cm from the tip.
