Problems solved by technology

[0003] There is such a problem in the existing light bulb type fluorescent lamp, that is, the fluorescent tube 4 and the lighting circuit 5 generate heat while the inside of the casing 2 is sealed, so the heat will be sealed in the space formed in the casing 2. The electronic components 5b and even the phosphor film (not shown) coated on the inner surface of the fluorescent tube 4 will be damaged by heat, resulting in a shortened lifetime

Embodiment Construction

[0028] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0029] Implementation form 1

[0030] A lightbulb-type fluorescent lamp with a rated power of 13 W as the first embodiment of the present invention has a total length of 120 mm and a maximum outer diameter of 60 mm. Such as figure 1 As shown, the outer container 3 is formed of a translucent glass-made or resin-made spherical bulb 1 and a resin-made shell 2 such as polybutylene terephthalate (PBT). The outer container 3 accommodates three U-shaped tubes 4a (only two are shown) with an outer diameter of 11 mm connected in bridge form to form a fluorescent tube 4 that forms a discharge circuit, and a lighting circuit for lighting the fluorescent tube 4 . 5. And a holder 6 supporting one end facing the fluorescent tube 4 and supporting the lighting circuit 5 on the other side opposite to the fluorescent tube 4 . In particular, the lighting circuit 5 is acco...

Abstract

A tubular light bulb device includes an arc tube, a lighting circuit for lighting the arc tube, a case housing the lighting circuit and having a base at one end, and a heat-transferring member disposed in the case for conducting heat from a space formed in the case to the base. This allows the tubular light bulb device to discharge heat in the space formed in the case to the outside to reduce temperature of a phosphor film and electronic parts of the lighting circuit, whereby increased life can be obtained.

Description

technical field [0001] The present invention relates to a spherical tube lamp device, in particular to a spherical tube lamp device with a fluorescent lamp and a lighting circuit in a shell and a spherical bulb. Background technique [0002] Existing spherical tube lamp devices such as bulb-type fluorescent lamps such as Figure 6 As shown, there is a fluorescent tube 4, a lighting circuit 5 for lighting the fluorescent tube 4, and an E26 type lamp cap 7 installed at one end of the shell 2 in the outer container 3 made of a spherical bulb 1 and a resin shell 2. . In particular, the lighting circuit 5 is accommodated in the casing 2 . In addition, the lighting circuit 5 has a wiring board 5a and electronic components 5b mounted on the wiring board 5a. [0003] There is such a problem in the existing light bulb type fluorescent lamp, that is, the fluorescent tube 4 and the lighting circuit 5 generate heat while the inside of the casing 2 is sealed, so the heat will be sealed...
