Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an edge light type self light emitting nameplate unit.

[0002]

2. Description of the Related Art Heretofore, doors have been hung around gates, entrances, and the like of buildings such as detached houses and condominiums. A self-luminous nameplate unit with a built-in is often used. For example, FIGS. 9 (a) and 9 (b)
It shows an example of the self-luminous nameplate unit. The self-luminous nameplate unit illustrated in FIGS. 9A and 9B includes a transparent edge light panel body (A) having translucency, and a light source (B) provided immediately above the edge light panel body (A). The light from the light source (A) enters the inside from the upper end surface of the edge light panel body (A) and reflects and refracts with the front and back surfaces of the edge light panel body (A) as boundary surfaces, and the front side The edge light panel body (A) itself emits surface light. Thereby, for example, a seal-shaped nameplate character (C) provided on the back surface of the edge light panel body (A) emerges, and the visibility is improved. The self-luminous nameplate unit in which the edge light panel body (a) emits surface light by the light from the light source (a) is called an edge-light type self-luminous nameplate unit.

In the conventional example shown in FIG. 9 (a), the edge light type self-luminous nameplate unit is mounted on a wall (e) or the like via a mounting base (d). Also,
The light source (a) may be provided not only directly above the edge light panel body (a) but also beside or below the edge light panel body (a). In this case, the light from the light source (a) is provided on the edge light panel body (a). The light is irradiated to the left and right end faces and the lower end face and enters the inside.

[0004]

However, in the conventional edge light panel type self light emitting nameplate unit as described above, there is a point to be improved with respect to the light source. That is, in this edge light type self-luminous nameplate unit,
Surface light of the edge light panel body (A)
In order to sufficiently increase the visibility of the light source, a light source (a) that can generate a large amount of light is required, but such a light source (a) generally consumes a large amount of power, In addition, a fluorescent lamp capable of obtaining a large amount of light with low power consumption has a problem in that the lamp itself is large and its lighting circuit and the like become large, so that the entire nameplate unit becomes large.

Therefore, it is conceivable to use an LED (light emitting diode) which is low power and small as the light source (a). In this case, it is necessary to arrange LEDs easily and easily from the viewpoint of downsizing of the nameplate unit itself. Further, since the LED has a smaller light quantity than the fluorescent lamp, it is necessary to effectively make the light enter the inside of the edge light panel body (A).

The invention of this application has been made in view of the above circumstances, and solves the problems of the prior art.
It is an object of the present invention to provide a new edge light type self-luminous nameplate unit in which LEDs are easily accommodated and easily arranged, and in which LED light can be effectively incident into an edge light panel body.

[0007]

D provides an edge light panel type self-luminous nameplate unit, wherein the light is disposed in the LED recess so that the light enters the inside of the edge light panel body from the light incident surface portion of the LED recess. .

Accordingly, the LED hardly protrudes from the edge light panel body, and can be mounted in the nameplate unit with good fit. Therefore, the size of the nameplate unit can be reduced, and the LED having strong directivity can be obtained. Light efficiently enters the inside of the edge light panel body from the light incident surface portion of the LED recess, and effective surface light emission of the edge light panel body can be realized.

Further, in the invention of the present application, in the above-mentioned nameplate unit, the L is set so that a pair of LEDs face each other.
The fact that an ED recess is provided is provided as an embodiment thereof. As a result, the positions of the pair of LEDs at the opposing positions with respect to the edge light panel body, for example, the vertical height position and the front / rear position, are substantially the same (including exactly the same; hereinafter the same). Fine adjustment of the position at the time of disposition in the recess is not required, and not only the accommodation in the unit is further improved, but also the position of each LED with respect to the light entrance surface of the LED recess becomes substantially the same,
The angle of incidence on the edge light panel body is almost the same,
The surface light emission of the edge light panel body by the plurality of LEDs becomes more effective due to the improved uniformity.

According to the invention of the present application, in the above-mentioned edge light type self-luminous nameplate unit, for example, when a reflection plate is provided on the back side of the edge light panel, the LED is integrated with the support plate member. And the supporting plate member has a plate piece extending at an end along the longitudinal direction thereof, and the LED is connected to the L of the edge light panel body.
In addition to the arrangement in the concave portion for ED, the plate piece of the support plate member may be sandwiched between the back surface of the edge light panel body and the reflection plate body.

Thus, the LED integrated with the support plate member has a simple structure in which the plate piece of the support plate member is sandwiched between the back surface portion of the edge light panel body and the reflection plate body. It is fixed to the edge light panel body without using separate fixing means such as. When a pair of LEDs is used, both LEDs can be handled as one unit with the support plate member, and mounting and fixing are easy.

When the support plate member is a board (ie, a circuit board or a wiring board), the board not only has its plate piece sandwiched by the edge light panel body and the reflection plate body, but also has It is also insulated by contacting the reflection plate.
