Description

[Detailed Description of the Invention] Industrial Field of Use The present invention relates to a display device that can be used to display the volume display or signal switching display of audio equipment or the like using a light emitting source such as a lamp.

2. Description of the Related Art In general, as a method for displaying the volume of audio equipment, etc., a large number of light emitting sources such as light emitting diodes are arranged in a stepped manner, and a sheet for diffusing the light from the light emitting diodes is provided at an angle above the light emitting sources. A method is used in which a part of the diffusion sheet emits light by lighting up to indicate the volume level.

A conventional display device such as a light emitting diode will be described below with reference to the drawings.

FIG. 4 shows the entire display section of a conventional display device, and FIG. 5 is a sectional view taken along line AA in FIG.
The figure is a view taken in the direction of arrow B in FIG. 4.

1 is a main body cabinet, 2 is a mirror plate attached to the main body cabinet 1, 3 is a diffusion sheet for diffusing light and uniformly illuminating the areas hit by the light, and the parts other than the transparent parts 3a to 3c are printed. This prevents light from passing through. Reference numeral 4 denotes a light emitter holding piece that holds the light emitter 6, and is attached to the printed circuit board 5. After attaching the diffusion sheet 3 to the holding piece 4, the printed circuit board 5 is attached to the main body cabinet 1.
inserted into. 7 is a transparent protective window glued to the main body cabinet 1.

The operation of the display device configured as above will be described below with reference to the drawings.

FIG. 6 is a view seen from the direction of arrow B in FIG.
It is visible as b, 8c. When the volume is normal, the window 3b emits light and the image 8b reflected on the reflector 2 also appears to emit light; when the volume is high, the windows 3a, 3b, and 3c emit light, causing the image reflected on the reflector 2 to appear as if it were emitted. 8a, 8b, and 8c also appear to emit light.
The light emitting sources 6 are controlled to be sequentially switched by an electric circuit.

Problems to be Solved by the Invention However, with the above configuration, if you want the diffusion sheet to emit bright light, you will have to use a very bright light source, which will increase the cost, and since the diffusion sheet is white, It has the disadvantage that it is difficult to confirm whether it is lit or not when it is exposed to strong light from the outside. Also, as shown in Fig. 5, when viewed from the direction of arrow B in Fig. 4,
When the width H of the light-emitting part of the diffusion sheet and the width D of the light-emitting part of the diffusion sheet reflected on the mirror plate 2 are not equal to D=H when the angle α is other than 45°, use a mirror plate as in this example to make it look like an X-shape. When attempting to do so, there was a major problem in that the design would be unbalanced.

Means for Solving the Problems In order to solve these conventional problems, the present invention arranges the light emitting sources in a stepped manner so as to protrude beyond the inclined nameplate, and also reduces the amount of protrusion of the light emitting sources. It is characterized by matching the width of the top surface of the light source.

Effects With the above configuration, the top surface of the light source projected on the mirror plate and the side surface of the light source coming out from the nameplate are equally visible, and the light from the light source is diffused to make the light source visible directly. There is no need for a sheet to protect the light, making it inexpensive and bright because there is no loss of light when it passes through. In addition, by adjusting the amount of protrusion of the light source from the nameplate, the width of the light source reflected on the mirror surface and the width of the side surface of the light source can be matched even if the angles of the nameplate and mirror surface are arbitrarily selected. This allows for a balanced display.

Embodiment Hereinafter, a display device according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows the display part of the display device in one embodiment of the present invention, and FIG. 2 shows the C of FIG. 1.
-C section, FIG. 3 is a view taken along arrow D in FIG.

15 is a main body cabinet, 9 is a mirror plate attached to the main body cabinet 15, and 10 is a name plate made of vinyl chloride or the like, and has holes through which light emitting sources 13a, 13b, and 13c come out. 11 is a light emitting source 13a, 13
This is a light emitting source holding piece that holds parts b and 13c, and is attached to the printed circuit board 12. The printed circuit board 12 is inserted into the main body cabinet 15 after the nameplate 10 is attached to the holding piece 11. 14 is a transparent protective window glued to the main body cabinet. The holding piece 11 connects the light emitting sources 13a, 13 through the hole in the nameplate 10.
Light emitting sources 13a, 13 are located at the positions where b, 13c exit
b, 13c are retained.

The operation of the display device configured as described above will be explained.

FIG. 3 is a view seen from the direction of arrow D in FIG.
I can see c. When the volume is normal, the light source 13b emits light, and the top surface 16b of the light source reflected on the reflector plate 9 appears to emit light; when the volume is high, the light sources 13a, 13b, and 13c emit light, causing reflection. The upper surfaces 16a, 16b, and 16c of the light sources reflected on the plate 9 appear to emit light,
Displays that the volume is high.

As described above, according to this embodiment, the nameplate 10 has a plurality of light emitting sources 13a, 13b, and 13c tilted.
Light emitting source 1
By matching the amount of protrusion of the side surfaces 3a, 13b, and 13c when viewed from the front with the width of the top surface of the light source, the top surface 16a of the light source projected on the mirror plate as shown in FIG. 16b, 16c and the sides of the light emitting sources 13a, 13b, 13c coming out from the nameplate, even when the angle β is other than 45° as shown in Figure 2.
It can be configured so that DD=HH,
It becomes possible to display changes in volume, etc. in a well-balanced design.

Although the name plate 10 is used in this embodiment, it may be omitted if the holding piece 11 is used for printing, etc. Further, the holding piece 11 may be omitted and the main body cabinet 15 may be used instead of the name plate 10.

Effects of the invention As described above, the present invention arranges multiple light emitting sources in a stepped manner so as to protrude beyond the slanted nameplate. By matching the widths of the top surfaces of the light sources shown in , it is possible to realize a display device with a well-balanced design when trying to make multiple light sources appear by using a mirror surface, as in this example. It is. Furthermore, by directly showing the light emitting source, a bright display can be provided at low cost.
