このとき、第２の基板４は窓部２の前面窓部２ａと枠部２ｂの接続部と同一平面上に設けられている。つまり、第２の基板４は壁９の防護領域側の面と同一平面上になる位置に設けられるので、枠部２ｂの周囲を壁９で覆うことが可能となる。
The wall 9 as an installation surface is provided with an opening having a size substantially the same as that of the frame portion 2b of the light alarm device 1 so that only the front window portion 2a of the window portion 2 is exposed to the protection area side. It has been.
At this time, the 2nd board | substrate 4 is provided on the same plane as the connection part of the front window part 2a of the window part 2, and the frame part 2b. That is, since the second substrate 4 is provided at a position on the same plane as the surface of the wall 9 on the protection area side, the periphery of the frame portion 2b can be covered with the wall 9.
次に、防護領域内での監視状態及び火災状態における光警報装置１の動作を説明する。
監視状態において、光警報装置１は、壁９に設けられた開口部から窓部２の前面窓部２ａのみが防護領域側に露出するように設けられる。そして、防護領域側の窓部２（前面窓部２ａ）から外光が入射すると、前面窓部２ａを透過した外光は第２の基板４に照射され、第１の基板３に照射されないので、第１の基板３に設けられた制御部（電子部品）を外光から保護することが可能となる。
Next, the operation of the light alarm device 1 in the monitoring state and the fire state in the protection area will be described.
In the monitoring state, the light alarm device 1 is provided so that only the front window portion 2a of the window portion 2 is exposed to the protection area side from the opening provided in the wall 9. Then, when external light is incident from the protection area side window 2 (front window 2a), the external light transmitted through the front window 2a is irradiated onto the second substrate 4 and not onto the first substrate 3. The control unit (electronic component) provided on the first substrate 3 can be protected from external light.
さらに、窓部２の枠部３側面から入射する外光は壁９によって遮断されるので、側面からの外光も遮断できるものとなっている。 Furthermore, since the external light which injects from the frame part 3 side surface of the window part 2 is interrupted | blocked by the wall 9, the external light from a side surface can also be interrupted | blocked.
次に、防護領域内で火災等の異常が発生すると、防護領域に設けられた図示しない火災感知器等の警報器は、無線または有線によって警報信号を出力する。 Next, when an abnormality such as a fire occurs in the protection area, an alarm device such as a fire detector (not shown) provided in the protection area outputs an alarm signal wirelessly or by wire.
光警報装置１は、警報器から出力された警報信号を受信すると、制御部が発光部６を発光する制御信号を出力する。制御部から出力された制御信号は、接続部７を介して第２の基板４に出力され、発光部６が発光する。 When the light alarm device 1 receives the alarm signal output from the alarm device, the control unit outputs a control signal for causing the light emitting unit 6 to emit light. The control signal output from the control unit is output to the second substrate 4 through the connection unit 7 and the light emitting unit 6 emits light.
発光部６から発せられた光は放射状に広がり、鋸状に形成された前面窓部２ａの内面に当たり、外部に拡散される。
これにより、前面窓部２ａが全体的に発光するので、防護領域内の人に気がつきやすくなっている。
The light emitted from the light emitting portion 6 spreads radially, hits the inner surface of the front window portion 2a formed in a saw shape, and is diffused to the outside.
Thereby, since the front window part 2a emits light entirely, it becomes easy to notice the person in a protection area.
このように、第２の基板４を第１の基板３と略同一またはそれ以上の大きさに形成し、第２の基板４は、第１の基板３より防護領域（前面）側に設けたので、窓部２の前面窓部２ａから入る外光を第２の基板４で遮光し、窓部２の枠部２ｂ側面から入る外光を壁９によって遮光するので、第１の基板３に直接外光が当たることを防止できるものとなっている。
これにより、第１の基板３に設けられた制御部等の電子部品の劣化を防止できる。
In this way, the second substrate 4 is formed to be approximately the same size as or larger than the first substrate 3, and the second substrate 4 is provided closer to the protection region (front surface) side than the first substrate 3. Therefore, the external light entering from the front window portion 2a of the window portion 2 is shielded by the second substrate 4, and the external light entering from the side surface of the frame portion 2b of the window portion 2 is shielded by the wall 9, so that the first substrate 3 It can prevent direct exposure to outside light.
Thereby, deterioration of electronic parts, such as a control part provided in the 1st substrate 3, can be prevented.
なお、窓部２は前面窓部２ａ及び枠部２ｂを一体にして形成されているものとしたが、それぞれ別体に形成し、係合させるようにしても良い。 In addition, although the window part 2 shall be formed integrally with the front window part 2a and the frame part 2b, you may make it form in a separate body, respectively, and may make it engage.
また、前記実施の形態では、警報器が防護領域の異常を検出するものとしたが、光警報装置１自体が防護領域の異常を検出する構成であっても良い。
また、窓部２の形状は円柱状に限定したものではなく、用途に応じて角型や球状としてもよい。
Moreover, in the said embodiment, although the alarm device shall detect the abnormality of a protection area, the structure which the optical alarm device 1 itself detects the abnormality of a protection area may be sufficient.
Moreover, the shape of the window part 2 is not limited to a cylindrical shape, and may be a square shape or a spherical shape depending on the application.
また、前面窓部２ａは、半透明の樹脂によって形成されているが、透明なガラス等、光を透過するものでもよい。
また、前記実施の形態では、第２の基板４に昇圧回路を備えているが、防護領域側の面とは反対側の面に制御回路等を配置してもよい。
Moreover, although the front window part 2a is formed with the translucent resin, you may permeate | transmit light, such as transparent glass.
