Description

[Detailed Description of the Invention] This invention relates to a discharge lamp apparatus such as a guide light or an emergency light.

As shown in the figure, this type of instrument is composed of an instrument frame 1 which is in the shape of a mouth when viewed from the front, and a light-transmitting plate 2 that closes off the front and back sides of the instrument frame 1, respectively.

The transparent plate 2 is supported by a frame 3, and is attached by fitting the frame 3 into the instrument frame 1.

Inside the appliance frame 1, there is a socket 4 in addition to the discharge lamp. Batteries for emergency power5. Circuit components such as a high frequency inverter for lighting the discharge lamp using the battery 5 as a power source 6. A ballast 7 used for lighting a discharge lamp using a commercial AC power source is housed therein.

Note that 8 is a transparent plate that closes a window formed in the bottom wall 1A of the instrument frame 1.

By the way, in the conventional device of this kind, as shown in FIG.
A and a case 10 containing nine ballast circuit components were also attached to the bottom wall 1A.

Since the individual parts are attached directly to the instrument frame 1 in this way, the attachment work is extremely troublesome, especially when the instrument frame 1 is large.

Also, like a socket, a socket stand 9 must be prepared separately for installation, which has the disadvantage of increasing the number of parts used.

This idea aims to simplify the installation of parts necessary for lighting and to reduce the number of parts used for installation.

An embodiment of this invention will be explained with reference to FIGS. 2 and 3.

FIG. 2 is a perspective view showing a state in which the transparent plate 2 is removed.
FIG. 3 is an exploded perspective view.

As can be easily understood from FIG. 3, in this invention, a mounting base 11 which is U-shaped when viewed from the front is prepared, and the sockets 4 are mounted on the opposing surfaces of the opposing upright walls 11A and 11B.

Further, a battery 5 and a ballast 7 are fixed to the surface of the base wall 11C.

In the illustrated example, the battery 5 is mounted so as to be pressed by a spring spring 12, and the stabilizer 7 is fixed with screws 13, but the fixing means is not limited to these and any other means can be used.

Further, a window 14 is formed in the base wall 11C, and a transparent plate 8 is attached to the window 14 so as to close the window.

The window 14 is formed at a position facing a window 15 formed in the bottom wall 1A of the instrument frame 1 when the mounting base 11 is housed and fixed in the instrument frame 1, as will be described later.

A printed circuit board 17 loaded with circuit components 6 is installed in a space surrounded by the back surface of one upright wall 11B and a wall surface 16 formed by bending both side edges of this upright wall 11B.

For fixing at this time, it is preferable to form a cut and raised piece 18 on the wall surface 16 and to engage the side edge of the printed circuit board 17 and fix it.

The mounting base 11 is housed inside the instrument p1, and is fixed to the bottom wall 1A of the instrument frame 1 with screws, cut-and-raise pieces, or the like.

Here, before storing the mounting base 11 in the instrument frame 1,
As described above, attach the socket 4 to the mounting base 11. Battery 5. Ballast 7. Attach the printer I, board 17, transparent plate 8, and all other necessary parts.

After that, the mounting base 11 is stored and fixed inside the instrument frame 1.

In this fixed state, the standing walls 11A, 11
If the interval B is formed according to the required dimensional accuracy, the interval between both sockets 4 will be maintained at the required dimension even when the socket 4 is housed and fixed in the fixture frame 1, so there will be no problem in installing the discharge lamp. do not have.

Also, the printed circuit board 17 and the circuit components 6 loaded thereon.
Since it is located in a space surrounded by the upright wall 11B, the wall surface 16, and the side wall 1B of the instrument frame 1, there is no need to use the case 10 as in the conventional case shown in FIG.

According to this invention detailed above, the following effects can be obtained.

(1) Since it is sufficient to simply fix the mounting base 11 to the instrument frame 1, the work of attaching it to the instrument frame 1 is extremely simple.

(2) Since each component can be attached to the mounting base 11 separately from the instrument frame 1, the work is simple.

(3) Circuit components 6. Since the printed circuit board 17 is located in a space surrounded by the upright wall 11B of the mounting base 11, the wall surface 16, and the side wall 1B of the instrument frame 1, the conventional case 10 is unnecessary.
