[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called collective light-emitting device using a collective light-emitting lamp provided with a plurality of light-emitting lamps and provided with these light-emitting lamps adjacent to each other.
The present invention relates to a collective light emitting hood that blocks a collective light.

[0002]

2. Description of the Related Art Light bulbs and light emitting diodes (Light-E)
A light emitting body such as a light emitting diode (mitting diode, LED) is used as a so-called light emitting lamp such as an indicator light or a signal light for performing various displays by turning on or off the light emitting body. The light-emitting lamps are used for various display devices such as information transmission devices such as large-scale video projectors on the street and products for calling attention such as traffic signals and warning lights. In the field of mechanical devices, such a display device is often used as an indicator light for indicating an operation state of a machine in a switchboard, a control panel, or the like.

[0003] The display device used in this mechanical device is as follows.
For example, when a failure occurs in a part of the mechanical device, the light emitting lamp is turned off to notify the abnormal situation. However, in a display device for a mechanical device having a complicated configuration, a light emitting lamp corresponding to each of the components is prepared, and if these light emitting lamps are provided at a certain interval on a switchboard or the like, the display becomes difficult. The device becomes large and not practical.

To cope with such a situation, it is common practice to use a so-called collective light emitting lamp in which a plurality of light emitting lamps are adjacent to each other in advance. In other words, if this collective light emitting lamp is used, a large amount of information can be displayed even with a display device having a limited size.

[0005] A switchboard, which is a display device for indicating the operating state of the machine, will be briefly described. FIG. 11A is a front view of a housing 1 of a switchboard containing a normal switchboard provided with a light emitting lamp, and FIG. 11B is a side view thereof. In the drawing, 1 is a cabinet of a switchboard, 2 is a front external door, 3 is a glass window for inspection, 4
Is an internal panel for mounting a collective indicator light, and 5 is a light-emitting lamp such as an indicator light or a signal light.

FIG. 12 is a schematic sectional view enlarging a portion B in FIG. 11B, and FIG. 13 is a schematic sectional view showing the configuration of the light emitting lamp 5. As shown in FIG. In FIG. 12, arrows indicate a state in which external light is applied to the front of the light emitting lamp. In FIG. 13, reference numeral 6 denotes an illuminated surface glove, which is provided with a luminous body 8 such as an LED or a light bulb inside. Although not specifically shown here, the inner panel 4 has a hole into which the luminous body 5 can be inserted. After the luminous body 5 is inserted into the hole, the luminous body 5 is fastened to fix the luminous body 5 to the inner panel 4. It is fastened and fixed using the attached ring.

[0007] When an abnormality occurs in a machine or the like under the control of the switchboard, the internal panel 4 changes the color of the light-emitting lamp 5, blinks or turns off the light, etc., to identify the abnormal situation that has occurred. It is configured as shown in FIG. Usually, when the internal panel 4 is inspected, the inspection glass 3 is used.
The internal panel 4 is visually recognized from.

[0008]

In the internal panel 4 having such a light emitting lamp 5, depending on the season and time, FIG.
As shown in FIG. 1B and FIG. 12, external light such as sunlight or illumination light often passes through the inspection glass 3 and illuminates the light emitting surface of the light emitting lamp 5. In this case, the original luminous luminance of the luminous body 8 cannot be obtained, and the luminous body 8 tends to be difficult to visually recognize.

In order to solve this problem, Japanese Patent Application Laid-Open No. 5-197
In Japanese Patent Application Publication No. 02-203, there is proposed a light emitting diode display and a display panel in which a covering state for a light emitting diode element can be selected according to a use situation. In this light-emitting diode display, a hood is placed on the outer shell of the display body to improve the visibility, but this hood is attached to only a specific display, and a commercially available light-emitting lamp or It is difficult to use it for a display device such as an existing switchboard, and the problem has not yet been solved.

Many attempts have been made to provide a hood for each light-emitting lamp. However, a hood that can handle this single light-emitting lamp cannot be used as a collective light-emitting lamp as described above. However, the problem has not been solved yet.
In addition, a method of providing one hood for a plurality of light emitting lamps has been attempted. This hood for a plurality of light-emitting lamps can cope with the case where the collective light-emitting lamp consists of two or three light-emitting lamps, but when it consists of 10 to 20 light-emitting lamps, the hood itself becomes huge. It is not practical.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and has as its object to provide a collective light-emitting lamp display device having a plurality of light-emitting lamps, such as an indicator light and a signal light, in which external light reduces visibility. Even if there is, it is an object of the present invention to provide a light-emitting device for a collective light-emitting lamp in which a user can surely visually recognize a light-emitting state of a light-emitting lamp without being disturbed by external light.
