Description

  The present invention relates to a fluorescent lamp device having an arc tube having a bent discharge path and a lighting fixture using the fluorescent lamp device.

  Conventionally, for example, as shown in Patent Document 1 below, the shape of an arc tube is bent into a substantially U shape, or the ends of two straight tube glass tubes are joined together to form a substantially H shape. A so-called compact fluorescent lamp in which a bent discharge path is formed according to the configuration is widely used.

  This type of fluorescent lamp is configured as a single-end fluorescent lamp with a filament electrode sealed at both ends of the arc tube and a single base attached. Is widely used as surface light sources for table lamps, base lights, downlights, etc.

  On the other hand, in this type of fluorescent lamp, the lighting device for lighting the lamp is not installed in the fluorescent lamp, but is installed on the fixture side, and the lighting fixture has a built-in lighting device composed of an expensive inverter or the like. Thus, the cost of equipment increases, and in recent years, especially in the situation where renewal of stores and the like is frequently performed, how to reduce the equipment cost has become an important issue.

  For this reason, there is a method of using a fluorescent lamp device built in the lamp side as a light source without providing an expensive lighting device on the fixture side (for example, Patent Document 2).

The one shown in Patent Document 2 has a configuration in which one end of a bent bulb is inserted and held in a storage case, a circuit board of a lighting device is stored in the storage case, and a power receiving pin is provided in the case cover. This is a so-called one-piece compact fluorescent lamp device incorporating a lighting device.
JP-A-8-17335 JP-A-6-283139

  The use of this fluorescent lamp device with a built-in lighting device makes it possible to reduce the cost of equipment. On the other hand, in recent years, the fluorescent lamp device itself has been required to be reduced in size due to power saving and space saving. The tube is further miniaturized.

  In accordance with the miniaturization of the arc tube, it is necessary to reduce the size of the entire fluorescent lamp device by reducing the size of the case for supporting the arc tube and accommodating the lighting device.

  In particular, it is necessary to achieve a reduction in the size of the entire fluorescent lamp device by making the outer diameter of the arc tube thinner and reducing the height of the case in accordance with the small-diameter arc tube to reduce the thickness. It is required to configure at least a height dimension substantially equal to the outer diameter dimension of the arc tube.

  As described above, when the case for housing the lighting device is thinned, the space for housing the wiring board on which the lighting component of the lighting device is mounted becomes narrower, and the electricity for connecting the wiring board to the arc tube and the power source is reduced. Since the wiring with the terminal portion is performed in a narrow space, the assembly work of the lamp becomes complicated.

  In Patent Document 2, the tip of a wire electrically connected to a lighting circuit board and a pair of electrodes is inserted into a power receiving pin made of a pressure contact pin from the inner end to the outer end. This improves workability during assembly.

  However, since Patent Document 2 has a configuration in which a power receiving pin is provided inside the case cover, the connection between the power receiving pin and the lighting circuit board provided in the case body needs to be performed from the back side of the case cover. Moreover, since the power receiving pin is an extremely small part, wiring work is difficult.
