Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates primarily to a compact fluorescent light fixture constructed to be compatible with conventional incandescent light bulbs.

Conventional structure and its problems In the past, so-called fluorescent lamps with bulb bases that have such compatibility have not been commercialized very often.
There are two types of lamps, one with a replaceable fluorescent lamp and the other with a so-called disposable type with a replaceable fluorescent lamp.

The former method requires a socket to replace the fluorescent lamp, so it is difficult to miniaturize the device, and the wiring portion must have sufficient insulation. The latter method is advantageous for miniaturization since there is no need to replace the fluorescent lamp, but unless the arrangement of parts and connection relays are carefully considered, the advantages cannot be fully utilized and productivity will deteriorate.

Purpose of the Invention The present invention has been made in consideration of the above-mentioned problems, and an object of the present invention is to provide a fluorescent light fixture that is compatible with incandescent light bulbs, does not hinder productivity, and can be made smaller. That is.

In order to achieve the above object, the present invention provides a chassis provided with an electrical connector on the upper surface and a ballast provided in the center of the lower surface, a C-shaped fluorescent lamp provided so as to surround the ballast, and this fluorescent lamp. Both ends of the fluorescent lamp are held in a notch provided in an opposing standing piece provided between both ends of the light lamp, and both ends of the glow lamp are held in a notch provided in another opposing standing piece. The compact fluorescent lamp device is equipped with an insulating box that is made of aluminum and a glove that covers the bottom surface of the chassis, and the lead wires of each of the electrical components are connected and relayed within the insulating box.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view when assembled, FIG. 2 is a bottom view of the chassis, and FIG. 3 is a perspective view of the main parts.

In the figure, reference numeral 1 denotes a chassis, which has an electrical connector 2 on its upper surface and a ballast 3 fixedly attached to the center of its lower surface. The electrical connector 2 may be of the same type as a light bulb cap or of a hook-and-seal type. 4 is a C-shaped fluorescent lamp, which is provided so as to surround the ballast 3. Reference numeral 5 denotes an insulating box, which is fixed to the lower surface of the chassis 1 by means of adhesive or the like, and is provided in the space between both ends of the fluorescent lamp 4, and has two sets of opposing upright pieces 6, 6' and 7, 7'. and cutout portions 8, respectively provided in these upright pieces 6, 6', 7, 7'.
8' and 9,9'. And fluorescent light 4
Both ends of the glow lamp 10 are held in the notches 8, 8', and both ends of the glow lamp 10 are held in the notches 9, 9'. The entrance of each notch 8, 8', 9, 9' is formed slightly narrow, so when inserting each upright piece 6, 6',
7, 7' may be slightly twisted, and once inserted, it will be difficult to escape. In addition, in each standing piece 6, 6', 7, 7', notches 8, 8',
The insertion work will be easier if cuts a are provided around 9 and 9'. Note that the notches 8, 8', 9,
9' is not limited to having an entrance at the top as shown in the figure, but may be simply a round hole. In this case, to insert the fluorescent lamp 4 and the glow lamp 10, the upright pieces 6, 6' must be pushed inward, and then the upright pieces 7,
7' is preferably performed after pushing outward, and the notch a works particularly effectively when such a round notch is provided, making the insertion operation easier. Reference numeral 11 attaches a glove to cover the bottom surface of the chassis 1. Reference numerals 12 to 20 denote lead wires of the electrical components (electrical connector 2, ballast 3, fluorescent lamp 4, glow lamp 10), and lead wires 12 to 19 are connected and relayed within the insulating box 5. Although the lead wires 13 and 20 are from the electrical connector 2, the lead wire 20 is directly connected to the ballast 3 without any connection relay. Note that 21 is a support piece that supports the intermediate portion of the fluorescent lamp 4. This support piece 21 is fixed to the lower surface of the chassis 1.

In the above configuration, the space between both ends of the C-shaped fluorescent lamp 4 is used to arrange the insulating box 5 in which the glow lamp 10 is installed, which enables effective use of space and contributes to miniaturization. Moreover, the cutouts 8, 8', 9, 9' provided in the standing pieces 6, 6', 7, 7' of the insulating box 5 have the effect of stably holding the fluorescent lamp 4 and the glow lamp 10. . Furthermore, since the lead wires of each electrical component can be connected and relayed all at once within the insulating box 5, this contributes to improved productivity, and there is no fear that the connecting portions will come into contact with the chassis 1 or the ballast 3. Incidentally, since the fluorescent lamp 4 and the glow lamp 10 are of a lead wire type that does not require a socket, it goes without saying that they contribute to miniaturization.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention, a compact fluorescent lamp that does not impede productivity by devising component arrangement, component holding, and connection relay, and which can replace an incandescent bulb. The device can be realized and has great practical effects.
