えられる。(Prior art) Conventionally, this type of fluorescent lamp device has a lighting circuit such as a fluorescent lamp and a chiyoke ballast placed in the same space within the envelope, so the envelope is kept in a sealed state. When the fluorescent lamp is turned on, the temperature inside the envelope rises due to the heat from the fluorescent lamp and ballast, and this thermal effect causes the mercury vapor pressure of the fluorescent lamp to exceed the optimum value, reducing luminous efficiency. A problem arises. By the way, the cause of the temperature rise inside the envelope is due to the heat generated by the ballast and the fluorescent lamp as mentioned above, so the inside of the envelope is divided into the cover side and the glove side through a heat insulating plate. However, it is conceivable to house the lighting circuit components in the chamber on the cover side, and to house the fluorescent lamp in the chamber on the glove side.

A large amount of heat is generated near both ends of the lamp, and this heat raises the temperature inside the globe and heats the lamp bulb, causing a problem in that mercury vapor pressure increases. Therefore, in order to suppress the temperature rise inside the glove as much as possible, an important issue for this type of device is how to efficiently exhaust the heat from the fluorescent lamp to the outside.

is a cylindrical part 1 protruding from a metal heat dissipation partition plate 6
8, 18 and is in close contact with the inner surface thereof, the heat at both ends 16, 16 is transferred to the cylindrical portion 18, 1.
The heat is efficiently transmitted to the heat dissipation partition plate 6 side through 8. A heat dissipation wall portion 11 is provided on the outer circumference of the heat dissipation partition plate 6 and is exposed to the outside air by being exposed to the circumferential surface of the envelope 5. Heat is radiated to the outside of the envelope 5 by heat conduction between the wall portion 11 and the outside air. Therefore, the heat emitted from the fluorescent lamp 13 is less likely to be trapped inside the envelope 5, so the temperature rise inside the envelope 5 can be suppressed, and the mercury vapor pressure inside the fluorescent lamp 13 is kept in the optimum range. can be controlled to maintain high luminous efficiency. In particular, in this embodiment, since the cover 1 is also made of metal such as aluminum, the heat transferred from the fluorescent lamp 13 to the heat dissipation partition plate 6 is transmitted to the entire cover 1 through the contact portion between the heat dissipation partition plate 6 and the cover 1. This increases the heat dissipation area and contributes to improving the heat dissipation effect.

Therefore, the high-frequency electric field is absorbed by this conductive layer, so leakage to the outside is reduced, and communication failures and the like can be prevented.
