Abstract

PURPOSE:To provide the guiding lamp which enables an observer to easily recognize a progressing direction even from a remote place. CONSTITUTION:Substrates 4a, 4b are inclined with a back plate 2 and are mounted to a supporting plate 3 for bisecting the back plate 2 to the left and right laterally symmetrically with this supporting plate as a center. Plural pieces of light emitting diode devices 5a which emit green light are juxtaposed with the substrate 4a. Plural pieces of the light emitting diode devices 5b which emit red light are juxtaposed with the substrate 4b as well. A case 7 is mounted to the back plate 2 so as to cover the respective light emitting diode devices 5a, 5b mounted to the respective substrates 4a, 4b. The light emitting diode devices 5a, 5b mounted to this guiding lamp 1 are diagonally mounted with the substrates 4a, 4b and, therefore, irradiate light of respective colors toward the optical axes mis-aligned from each other. For example, the guiding lamp 1 is so mounted as to indicate the progressing direction to the observer by the irradiation direction of the green light.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide light for advancing an observer in a predetermined direction (for example, an emergency exit).

[0002]

2. Description of the Related Art A conventional guide light of this type indicates the traveling direction by an arrow, like a guide light for guiding a person to an emergency exit.

[0003]

However, the conventional example having such a structure has the following problems. That is, if the direction of travel is indicated by an arrow as in the conventional art, it is difficult to recognize the direction of the arrow from a distance, and the observer must approach the guide light in order to recognize the direction of travel. There is.

The present invention has been made in view of such circumstances, and an object thereof is to provide a guide light which enables an observer to easily recognize the traveling direction even from a distance.

[0005]

The present invention has the following constitution in order to achieve such an object. That is, the present invention is a guide light for instructing an observer of a traveling direction, in which two light-emitting devices having different emission colors are arranged side by side with their optical axes being shifted, and the irradiation direction of light of a specific color Is used to instruct the observer in the direction of travel.

[0006]

The operation of the present invention is as follows. That is,
Since two light emitting devices having different emission colors are arranged side by side with their optical axes displaced from each other, light of different colors is emitted from each light emitting device toward each optical axis. Therefore, if the advancing directions of the two emission colors are determined in advance, the observer can proceed toward the irradiation direction of the specific light, and thus the advancing direction can be easily recognized from a distance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The configuration of the guide light according to the embodiment of the present invention will be described with reference to FIG. In the figure, reference numeral 1 is an induction light according to the present embodiment, and a support plate 3 that divides a rectangular or square back plate 2 into left and right parts is provided upright along a longitudinal center axis of the back plate 2. Two substrates 4a and 4b are attached to be supported by the back plate 2 and the support plate 3 while being inclined with respect to the back plate 2 so as to be bilaterally symmetrical with respect to the support plate 3. On the substrate 4a, a plurality of green light emitting diode devices 5a (for example, 3 vertically 3 by 9 laterally in total) are arranged in parallel. On the other hand, the same number of red light emitting diode devices 5b as the green light emitting diode devices 5a are arranged on the substrate 4b. Further, the lead wire 6 connected to each of the light emitting diode devices 5a and 5b extends from the back surface of the substrates 4a and 4b to the back surface of the back plate 2. Further, so as to cover the light emitting diode devices 5a and 5b attached to the substrates 4a and 4b,
The translucent case 7 having a prismatic shape with curved corners is the back plate 2
Is attached to.

Each of the light emitting diode devices 5a and 5b attached to the guide light 1 having the above-mentioned structure has substrates 4a and 4b.
Are obliquely attached, and as shown by the arrow in FIG. 1, light of each color is emitted toward each optical axis.

Next, an example of how to attach the guide light 1 will be described with reference to FIG. FIG. 2 shows a case where a plurality of guide lights 1 are attached to a ceiling of a corridor at equal intervals so that lights of the same color are emitted in the same direction. In the figure, the solid line shows the irradiation of green light, and the dotted line shows the irradiation of red light. At this time, the observer M is guided in a predetermined direction by advancing in a direction in which green light can be seen. Further, when the observer M looks back, the observer M can see the red light, and the observer M can recognize that the traveling direction is not the traveling direction. In addition, the reason why the observer M is advanced in the direction in which the green light can be seen is that the green of the signal means the advance, and thus the observer M is easily familiar with the sense. However, the present invention is not limited to such a luminescent color, and any luminescent color whose traveling direction is defined in advance can be used. Further, although FIG. 2 shows the case where the guide light 1 is mounted on the ceiling of the corridor, the mounting method of the guide light 1 is not limited to this, and may be mounted on a wall.

Next, an embodiment in which the guide light is realized by another structure will be described with reference to FIG. FIG. 3 shows a guide light having a structure in which two color light emitting diode elements are attached to a single light emitting diode device. The structure of the guide light 10 will be described below. That is, for example, in the die pads 12a and 12b at the tips of the lead terminals 11 whose tips are bifurcated, the recesses 1 in which the side walls 13a and 13b in the respective center directions are raised
4a, 14b are formed, and in each of the recesses 14a, 14b,
The green light emitting diode element 15a and the red light emitting diode element 15b are respectively die-bonded, and these light emitting diode elements 15a and 15b are
The tip ends of the lead terminals 16a and 16b are connected to each other by wires 17a and 17b such as gold wires.
The light emitting diode elements 15a and 15b, the wires 17a and 17b, etc. are covered with a translucent epoxy resin or the like to form a package body 18. The package body 18 has a spherical shape at the left and right corners where the elements 15a and 15b are arranged, and has a lens effect.

Irradiation light from the light emitting diode elements 15a and 15b attached to the guide light 10 having such a structure emits light from the respective side walls 13a and 13 of the recesses 14a and 14b.
Since the irradiation of the other optical axis is blocked by the left and right lens effects of b and the package body 18, the light of each color is irradiated along the respective separated optical axes as shown by the arrows in FIG. . In addition, as a method of mounting the guide light 10, for example, a plurality of guide lights 10 are arranged in a line in the vertical direction or arranged in the vertical and horizontal directions so that light of the same color is emitted in the same direction.

In the embodiment, the guide lamp using the light emitting diode element has been described as an example, but the light emitting source is not limited to this, and for example, a fluorescent lamp or an incandescent lamp and a colored filter are used to emit two light. The color may be obtained.

[0013]

As is apparent from the above description, according to the present invention, two light emitting devices having different emission colors are arranged side by side with their optical axes shifted from each other, and the light emitting devices have different colors. Light is emitted toward each optical axis, and the direction of travel is instructed to the observer according to the irradiation direction of the specific light, so that the observer can easily recognize the direction of travel even from a distance.
