By the way, as shown in FIG. 2 (a), a fixture for a compact fluorescent lamp comprises a reflector 22 and a support 24 for supporting the lamp L on the reflector 22. Open type is generally composed,
As another structure, as shown in FIG. 2 (b), a compact fluorescent lamp L is vertically mounted so that the coldest point of the lamp (communication tube L2) is on the lower side. Although there are some designed appliances, there is no one that has a structure in which a compact fluorescent lamp is housed in a closed container at present.

[0004] The reason is that the compact fluorescent lamp is the coldest spot (the connecting tube L2) at the lamp tip.
If the temperature is not maintained below a certain temperature (for example, 70 ° C.), the lamp current will increase and the lamp life will be shortened. Therefore, it is essential to maintain the lamp at an appropriate temperature. When the lamp is housed in the fixture, the heat from the lamp is trapped in the fixture, the ambient temperature of the lamp rises and the temperature of the lamp rises. Increasing the temperature increases the luminous efficiency and reduces the luminous flux emitted from the lamp.

The reason why the heat absorbing plate 4a of the supporting bracket 4 is provided on the back side of the side on which the lamp light is emitted is to substantially reduce the efficiency of the apparatus. In the above structure, the heat at the tip (the coldest point) of the compact fluorescent lamp L is absorbed by the heat absorbing plate 4a of the support 4 and then transmitted through the heat conducting portion 4b, so that the heat radiation area is large. The heat is guided to the instrument body 1a and radiated to the outside of the instrument. Here, since the fixture main body 1a is installed at a ceiling or the like at a temperature of about 40 ° C., and the temperature difference from the compact fluorescent lamp L being lit is sufficiently large as 30 ° C. to 50 ° C. 4, the compact fluorescent lamp L
Can be efficiently cooled, and the temperature of the coldest point can be maintained at an appropriate temperature of about 50 ° C. to 60 ° C. in a thermal equilibrium state.

As described above, according to the present invention,
The supporting bracket that supports the tip of the compact fluorescent lamp is provided with a heat-absorbing part that absorbs heat from the lamp tip and a heat-conducting part that allows the heat to escape to the fixture body. Even when housed in a sealed container, the coldest point of the lamp can be cooled to an appropriate temperature, and an increase in lamp current and a decrease in luminous efficiency can be suppressed. As a result, it is possible to realize a sealed fluorescent lamp apparatus for a compact fluorescent lamp.
