Next, a first embodiment of the present invention will be described with reference to FIGS. In the figure, 1
Is a light emitting diode group in which the present invention is implemented. The light emitting diode group 1 includes a printed circuit board 2 having notched grooves 2a recessed from both sides at a plurality of locations in a longitudinal direction of a long plate surface.
And a light-emitting diode (light-emitting element, LED) 3 implanted for each of a plurality of substrate units 2b formed by being divided by the notch grooves 2a. Here, it is needless to say that the printed wiring board 2 is provided with necessary wiring for each board unit 2b (a resistor is further connected if necessary), and the light emitting diodes 3 implanted in each board unit 2b are It is arranged upright at one end edge of the board unit 2b (the upper plate thickness surface of the printed board 2). The respective light emitting diodes 3 are set to be connected to each other by a lead wire 4 wired in a loop on the other end edge (lower plate thick surface) of the adjacent substrate units 2b. The light emitting diode group 1 thus configured can be separated by bending the light emitting diode assemblies 5 in which one light emitting diode 3 is incorporated, one by one, through the notch groove 2a. In this separated state, each LED assembly 5
Are set to be connected by the lead wire 4.

The light emitting diode display 6 is constructed by appropriately attaching the light emitting diode assembly 5 to a base material. In the first embodiment, the base material 7 is made of an elastic material such as a rubber elastic material. It is formed of a flat metal material that does not deform. Here, in the present embodiment, one in which a large-diameter through-hole 7a is drilled and one in which a small-diameter through-hole 7b is drilled (substrate indicated by a virtual line in FIG. 1)
The base material 7 has a structure that can accommodate these two types of base materials (so-called punching boards).
b are formed in a plurality of rows vertically and horizontally, and the light emitting diode assembly 5 is set in these through holes 7a. Here, each of the through holes 7a and 7b is formed to have a larger diameter than the outer diameter of the light emitting diode assembly 5, and the outer diameter of the holder 8 covered with the light emitting diode assembly 5 as described later. It is formed corresponding to the diameter.

The holder 8 is formed of a rubber-like elastic material into a cylindrical shape, and the lower half of the light emitting portion 3a of the light emitting diode 3 is fitted in the cylindrical hole 8a in a resilient manner. The unit 2b is covered, and the light emitting diode assembly 5 in this state is set so as to be attached to the base material 7. On the outer peripheral surface of the holder 8, first and second flange portions 8 having upper surfaces formed in an inclined shape are provided.
b, 8c are integrally formed in two stages, upper and lower, and when the light emitting diode assembly 5 is forcibly fitted from the back surface (lower surface) side of the base material 7, the through holes 7a or 7b are formed.
Either the second flange portion (locking portion) 8c or the first flange portion (locking portion) 8b is set so as to reach the surface (upper surface) side of the substrate 7 while being elastically deformed. Thus, the light emitting diode assembly 5 with the holder 8 is set so as to be attached in a retaining shape corresponding to the hole diameter of the base material 7. That is, the outer diameter of each of the lower surfaces of the first and second flange portions 8b and 8c of the holder 8 is formed corresponding to the hole diameter of the through holes 7b and 7a. Is formed, the light-emitting diode 3 is mounted so that the second flange portion 8c is exposed on the surface side of the base material 7, and when the small-diameter through hole 7b is formed, the first flange portion 8b is formed. Is set in a state where the base material 7 is exposed.
In the case where the through holes 7a and 7b having large and small hole diameters are appropriately formed, it is possible to display a state in which the light emitting diodes 3 have different projection amounts and have a three-dimensional design. However, such adjustment of the protrusion amount is not necessarily performed by changing the hole diameter, but may be performed by providing a plurality of flange portions having the same outer diameter and locking the desired flange portion to the through hole. can do. Further, as the flange portion of the holder 8, only one flange portion 8c (in a one-step shape) corresponding to the hole diameter of the through hole 7a of the base material 7 is formed as in the second embodiment shown in FIG. Needless to say, it may be something.

In this manner, the light emitting diode assembly 5 with the holder 8 is fitted into the base member 7, so that the light emitting diode 3 is attached to the base member 7 in a retaining shape to form a light emitting diode display 6. That is, at this time, the light emitting diode assembly 5 divided from one light emitting diode group 1 is already electrically connected, and the light emitting diode assembly 5 with the holder 8 divided from the plurality of light emitting diode groups 1 is provided. Are attached to the base material 7 while appropriately laying them out, so that the electrical connection of the desired decorative pattern, character, logo mark, or the like can be made at the construction site. In this case, a diagram 10 such as a logo mark or a decorative pattern is drawn on at least one of the front and back surfaces of the base material 7 as shown in FIG. By selecting the through-hole 7a and fitting the light-emitting diode assembly 5 with the holder 8 therein, a diagram to be decorated with the light-emitting diodes 3 can be drawn quickly and accurately. The diagram to be drawn includes a difference in the light emission color of the light emitting diode and a difference in the light emission group (for example, light emission of the same light emission color may be performed by different control).
The light emitting diode assembly 5 includes a plurality of groups of light emitting diode assemblies 5 by changing the diagram in a different style (for example, changing the color, changing the thickness of the line, changing the shape like a dotted line or a wavy line).
When mounting, there is an advantage that mounting errors can be reduced. In this case, if the diagram 10 is drawn on the surface, there is an advantage that when the light emission is stopped, the drawn diagram 10 can be viewed as it is in the daytime or the like. In addition, when drawn on the back surface, there is an advantage that the fitting of the diode into the through hole can be easily performed from the back surface. However, the punching board is not limited to a board having a through hole formed on one surface, and a board having a through hole formed at a location required as an electric decoration can be similarly used. Further, the outer peripheral shape of the holder is not limited to a circular shape in a plan view, and may be a polygonal shape such as a square, a hexagon, or a non-circular shape such as an ellipse. In this case, it is preferable that the through hole formed in the base material also has a corresponding shape, but the shape is not necessarily limited as long as the through hole is forcibly fitted and prevented from coming off. As the retaining force, it is sufficient that the retaining is performed in a normal use condition. Therefore, if it is desired to change the luminescent color, it is easy to change the pattern by removing it by forcibly removing it. There is.

In the embodiment of the present invention configured as described above, the light emitting diode display 6 has a plurality of through holes 7a or 7b formed in a base material 7 serving as a base, and the through holes 7a or 7b are formed in these through holes 7a or 7b. It is sufficient to mount the light emitting diode assembly 5 with the holder 8 which has already been connected and connected by the lead wire 4. Therefore, by appropriately mounting the light emitting diode assemblies 5 of the plurality of light emitting diode groups 1, various designs can be provided. Light emitting diode indicator 6
Failures that can be easily assembled at the construction site, such as conventional ones, in which light emitting diodes pre-planted on multiple printed circuit boards are wired after planting, and laborious and complicated work is done on site Is gone,
Construction work on site can be simplified.

[0010] In addition, since this type can cope with two types of base materials 7 having different through-hole diameters, it is easy to cope, for example, when a commercially available punching board is purchased.

It should be noted that the present invention is not limited to the above-described first embodiment, and is not a substrate having inflexibility as in the first and second embodiments. As in the second embodiment shown in FIG. 8, a flexible base material 9 can be used. In this case, the light emitting diode assembly 5 is not covered with the holder by utilizing the flexibility of the base material 9,
It is directly fitted into the base material 9 as it is.
That is, the base material 9 of the third embodiment is formed in a substantially rectangular cylindrical shape by molding a rubbery elastic material, and has a rectangular space 9a that is long in the longitudinal direction. A through-hole 9b for inserting the light-emitting portion 3a of the light-emitting diode assembly 5 formed as described above is formed on the surface (upper surface) of the base material 9 with a predetermined gap therebetween. An insertion port 9c that is long in the longitudinal direction is formed on the back surface (lower surface). Attachment of the light emitting diode assembly 5 to the substrate 9 is performed by mounting the light emitting diode assembly 5 on the substrate unit 2.
The light-emitting portion 3a is placed in a direction parallel to the longitudinal direction of the base material 9, the light emitting portion 3a is applied to the base material insertion opening 9c, and the light-emitting portion 3a is pressed into the gap portion 9a as it is. In this mounting state, the light emitting diode light emitting unit 3
a is protruded and the lower part thereof is fitted in the cavity 9a, but the hole diameter of the through hole 9b is set smaller than the outer diameter of the light emitting part 3a, and the light emitting diode assembly 5 is 9 so as to be supported in a retaining shape. And even in this case, the plurality of light emitting diode groups 1
By attaching the light emitting diode assembly 5 in a desired arrangement state, a pre-wired light emitting diode display 6 can be obtained. In addition, not only a straight line but also a curved state can be freely displayed on the site easily. It can be realized.
