Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fluorescent lamp socket with a built-in starter.

Conventionally, it has been proposed that a glow starter is integrally attached to, for example, a socket for an annular fluorescent lamp (hereinafter simply referred to as a socket). However,
In this conventional type, the socket part of the glow starter must be installed inside the socket body, which complicates the structure of the body, and the glow starter itself is large, making it difficult to downsize the socket.
Also, because the glow starter has a relatively short lifespan and needs to be replaced, and because of its starting characteristics, it is necessary to provide external light to the glow starter, a part of the glow starter is protruded outside from the socket body. I was letting it happen. As a result, there are problems in that the socket looks unsightly and that the glow starter is more likely to be damaged when replacing the lamp.

On the other hand, instead of the glow starter, it has been proposed to use an electronic starter housed within the socket body, which generates the high-voltage pulse voltage necessary to start the lamp by combining a pulse transformer using ferrite and a semiconductor switch. . However, in this device, the pulse transformer occupies a large volume, the lighting circuit is complicated, so it cannot be miniaturized, and it is expensive, so it has not been put into practical use.

The present invention has been made based on this background, and it is an object of the present invention to provide a fluorescent lamp socket with a built-in starter that is inexpensive and compact.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

Reference numeral 1 denotes a case body of a fluorescent lamp socket made of, for example, urea resin, and four lamp pin insertion holes 2 are provided at positions corresponding to fluorescent lamp pins (not shown) on the front surface, each penetrating to the back surface. is formed, and an internal space 3 is formed behind the lamp pin insertion hole 2. Reference numeral 4 denotes a bottomed lid body made of, for example, urea resin, and is attached to cover the back side of the case body 1. Reference numeral 5 denotes a pair of contact pieces for connecting the output wires which are pressure-bonded to the ends of the pair of output wires 6, and are inserted and locked into the lower two of the lamp pin insertion lights 2. The end of the contact piece 5 on the lead wire connection side is disposed within the gap 3 of the case body 1 and is located sufficiently inward from the edge on the back surface side. 7 is an electronic starter consisting of a pulse generator made by combining a nonlinear dielectric element such as a ceramic capacitor with a nonlinear relationship between voltage and charge and a semiconductor switch such as an SCR, and converting these into a hybrid IC. It is located inward from the abutting side edge of the container body 1 and the lid body 4, and the entire body is housed between the housing body 1 and the lid body 4. 9 has one end connected to the electronic starter 7 and the other end soldered to the protruding ends of a pair of lead wires 8 protruding outward from the abutting side edge of the lid 4 for connecting the pair of electronic starters. The contact pieces are inserted and locked into the upper two of the lamp insertion holes 2 when the lid body 4 is coupled to the case body 1. Reference numeral 10 denotes a lead wire accommodating recess formed at the lower back side of the case body 1 so as to communicate with the internal space 3, and 11 an open lower part of the back side of the case body 1 so as to communicate with the recess 10. The lead wire outlet is not covered by the cover 4 when the cover 4 is connected to the case body 1. Therefore, the pair of lead wires 6 to which the contact pieces 5 are connected are located in the internal space 3 and in the lead wire accommodation recess 10.
and is led out of the socket through the lead wire outlet 11.

The fluorescent lamp socket configured as above is
Since the electronic starter is built-in, a lighting circuit is constructed by connecting the pair of lead wires 6 to the ballast and the power supply, and only two electrical connections to the lighting equipment are required, making it easy to use with glow starters or glow stars. No need for a gas socket.

As described above, the starter built-in fluorescent lamp socket according to the present invention has fewer main lead wires,
It is about the same size as a conventional fluorescent light socket, and a starter can be built in without increasing the price, making it extremely easy to assemble the lighting equipment and downsizing the entire lighting equipment. Can be done. In addition, since the lead wire is led out from approximately the middle of the socket toward the outer periphery, the lead wire does not get in the way when gripping the socket, such as when attaching or removing the socket to a fluorescent lamp, resulting in good workability. Moreover, there is little need for storage space for the lead wire, which is normally required behind the socket in the lighting equipment, and space utilization efficiency can be improved. Furthermore, since the entire starter is housed between the main body of the socket and the lid, there is no risk of damage to the starter.
