Abstract

PROBLEM TO BE SOLVED: To provide an indicating lamp that can perform a stable escape guide over long time without making facilities large sized and that can secure a high sight recognition capability. SOLUTION: A lamp 3 having a light source 25 with low power consumption and high brightness at the upper part of a pole 1 lights up the light source 25 by a battery. With this, it can inform of the neighbors by indicating a place of refuge in an emergency. Because the light source 25 consumes a low power, it can light a lamp for long time by the battery and bring a stable effect at the time of a stoppage of electric current. Because a plurality of high brightness LEDs are mounted with irradiation directions different from each other, the light source 25 can secure a high sight recognition capability in a wide range. Furthermore, by making an indication in higher position by mounting the lamp 3 into the upper part of the pole 1, it can make the escape guide of the inhabitants in wide area.

In addition, by mounting the lamp above the pole, the display is performed from a higher position, so that evacuation of a wide range of residents can be guided.

According to a second aspect of the present invention, in the first aspect, the light source includes a plurality of high-brightness LEDs provided in different irradiation directions. As described above, since the light source is provided with a plurality of high-brightness LEDs in different irradiation directions, high visibility over a wide range can be secured.

According to a third aspect of the present invention, in the second aspect, the plurality of light-intensity LEDs are arranged on the substrate and the light-intensity LEDs are inclined as they move from the center of the substrate to both sides, so that the light is emitted around the axis of the pole. The irradiation direction range was set to a predetermined angle or more. In this way, by arranging the plurality of light-brightness LEDs on the board and inclining the light-brightness LEDs as they move from the center of the board to both sides, the range of the irradiation direction around the axis of the pole is set to a predetermined angle or more. Visibility in all directions can be secured by the number of units. For example, if the range of the irradiation direction is set to 90 ° or more, the visibility in all directions can be secured by using four indicator lamps.

According to a fourth aspect of the present invention, in the second aspect, the substrate on which the plurality of high-brightness LEDs are arranged has an arc shape. As described above, since the substrate on which the plurality of high-brightness LEDs are arranged is formed in an arc shape, the irradiation directions are different from each other, and each high-brightness LED can be easily angled.

According to a fifth aspect of the present invention, in the first or second aspect, the battery is charged by a solar cell. Thus, the battery is charged by the solar cell,
Contribute to resource saving.

According to a sixth aspect of the present invention, in the third aspect, the solar cell is installed above the pole. in this way,
Since the solar cell is installed above the pole, a space for installing the solar cell can be secured without obstructing other members.
