Abstract

PURPOSE:To improve the water proofing property and to improve the accuracy of fluorescent lamps for displaying picture by inserting and arranging the lamps in recessed sections arranged in rows like a matrix. CONSTITUTION:Plural recessed sections 3 are arranged like a matrix in a fluorescent lamp fitting plate 2 provided in front of a main body housing and fluorescent lamps 7 for displaying picture, each of which is composed of a cap section 5 provided with an electrode section 4 at its rear end and a light emitting section 6 formed at the front side of the cap section 5, are inserted and arranged in the recessed sections 3. The projecting body 8 provided on the inner side face of each recessed section 3 is tightly adhered with the side face of the light emitting section 6 of each lamp 7. Therefore, the lamps 7 can be arranged accurately and, at the same time, fitting of the lamps 7 becomes easier.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application 1] The present invention relates to a mounting structure for an image display fluorescent lamp used as a display element in a large color display device or the like.

[Prior art l vt rice, ff171Jl=show-i, l: ut:'4a
Various image display devices A have been provided in which image display fluorescent lamps 7 of 1 (, (, i, 13 emissions) are arranged in a matrix to display a large image. An image display fluorescent lamp 7 for use in an image display device A such as
For example, there is one shown in Fig. 5. This one emits light at the front end of the base part 5 which has an electrode bin 4 at the rear end.
6 to form an image display fluorescent lamp 7, and as shown in FIG. It was to be placed in

12 is a drained piece.

[Problem to be Solved by the Invention 1] However, in the conventional example described above, since the printed circuit board 11, which is the connection part, is in direct contact with the outside air, a draining piece 12 is provided when the wind and rain become strong. There is a problem that water entering the object causes poor insulation on the printed board 11, and since the image display fluorescent lamp 7 is held on the printed board 11 via the electrode bin 4, the holding strength is weak. There was a problem in that the image display fluorescent lamps 7 were arranged unevenly due to the mounting force.

The present invention is intended to solve the above-mentioned problems, and its purpose is to provide an image display fluorescent lamp mounting structure that can improve waterproofness and arrangement accuracy.

1 Means for Solving the Problems In order to achieve the above object, the image display fluorescent lamp mounting structure of the present invention includes a plurality of fluorescent lamp mounting plates 2 disposed on the curved surface side of the main body housing 1 arranged in a matrix. A fluorescent lamp 7 for image display is formed by providing a light emitting part 6 at the front end of a cap part 5 having a row of concave parts 3 and an electrode part 4 at the rear end.
is fitted into the recess 3 of the fluorescent lamp mounting plate 2, and a protrusion 8 protruding from the inner surface of the recess 3 is attached to the side surface of the light emitting portion 6 of the image display II fluorescent lamp 7.

[Function 1] By fitting and arranging the image displaying fluorescent lamps 7 in the recesses 11s3 arranged in a matrix, the image displaying fluorescent lamps 7 can be properly arranged, and can also be fitted into the recesses 3 and fixed. The image display fluorescent lamp 7 can be easily attached, and its holding strength is high.Furthermore, since the protrusion 8 is in close contact with the side surface of the light emitting part 6, waterproofness is improved.

[Example 1] As shown in FIG. 2, the image display fluorescent lamp 7 is composed of a base part 5 having a lead wire 4a, which is an electrode &Is4, at the rear end, and a light emitting part 6 provided at the front end of the base part 5. It is. 9
is a lead wire extending from the light emitting part 6.The fluorescent lamp mounting plate 2 disposed on the front side of the main body housing 1 has a matrix-shaped recess 3 into which the image display fluorescent lamp 7 can be fitted and mounted. Multiple pieces are installed in a row. This recess 3
An opening 10 into which the cap 5 of the image display fluorescent lamp 7 can be inserted is provided on the back side of the display. Then, the base portion 5 is fitted into the opening 10, and the light emitting ff1s6 is fitted into the recess 11s3, so that the image display fluorescent lamp 7 can be fitted and attached to the recess 3. At this time, leads #i4a, 9 are connected to the inside of the fluorescent lamp mounting plate 2 [1].
] It is directly connected by soldering to a printed circuit board (not shown) provided at +1. As shown in FIG. 3, a plurality of elastic brim-shaped protrusions 8 are provided on the inner surface of the recess 193. This protrusion 8 is designed to come into close contact with the side surface of the light emitting section 6 when the image display fluorescent lamp 7 is inserted into the recess 3 . This is to prevent a gap from being formed between the outer peripheral side surface and the inner side surface of the recess 3. As the protrusion 8 comes into close contact with the side surface of the light emitting section 6, the inner surface of the recess 3 and the light emitting section 6
This will block the darkness from the sides, and improve the waterproofness against rainwater, etc. that infiltrates inward.

FIG. 4 shows another embodiment of the protrusion 8, in which the protrusion 8 is made of an elastic material, and when the light emitting part 6 is fitted into the recess 3, the protrusion 8 becomes the light emitting part. By crushing the outer peripheral side surface of the recess WS 6, the space between the inner surface of the recess 3 and the side surface of the light emitting section 6 is closed, and the light emitting WS 6 is tightly fixed within the recess 3.

1 Effect of the invention 1 As described above, the recesses provided in the fluorescent lamp mounting plate are arranged in a matrix, so that the image display fluorescent lamps can be arranged by fitting them into the recesses. It can be installed with high precision, and it is easy to fix the fluorescent lamp by simply fitting it into the recess.
The holding strength is also strong. Furthermore, since the protrusion protruding from the inner surface of the recess is brought into close contact with the side surface of the light emitting section of the image display fluorescent lamp, the protrusion closes the opening between the inner surface of the recess and the side surface of the light emitting section. This is particularly effective in improving waterproofness.
