It comes into contact with the tip end side of the receiving portion 31, and is elastically deformed so that the interval between the locking metal fittings 111 on both sides is narrowed. Then, as the locking metal fittings 111 on both sides pass over the distal end sides of the disposition portion 55 and the locking receiving portion 31, as shown in FIG. 111 is engaged with the tip end side of the lock receiving portion 31, and the display unit 13 is locked in a biased state in which it is pulled toward the guide light main body 34. This completes the construction of the guide light 10.
表示ユニット13を誘導灯本体34に取り付けることにより、図９に示すように、ガイド部109（保持部110）により、第１の支持部28の突起部29が壁部51の係止溝部52に係合した状態に保持し、誘導灯本体34が取付金具11から外れるのが防止される。さらに、図１１に示すように、導光板103の入射部115がガイド体69の導光板挿入部76に挿入される。これは、枠体100から後方へ突出する導光板103の入射部115の寸法が、ガイド部108，109よりも小さい寸法であるため、ガイド部108，109が誘導灯本体34に先に組み込まれることにより、導光板103の入射部115がガイド体69の導光板挿入部76に自動的に挿入される。また、ガイド体69の上下の遮光部75により、導光板103の入射面119が光源72に対向するように導光板103の入射部115が位置決めされるとともに、入射部115の上下面が覆われる。
By attaching the display unit 13 to the guide light main body 34, as shown in FIG. 9, the projection portion 29 of the first support portion 28 becomes the locking groove portion 52 of the wall portion 51 by the guide portion 109 (holding portion 110). The engaged state is maintained, and the guide light main body 34 is prevented from coming off the mounting bracket 11. Further, as shown in FIG. 11, the incident portion 115 of the light guide plate 103 is inserted into the light guide plate insertion portion 76 of the guide body 69. This is because the size of the incident part 115 of the light guide plate 103 protruding rearward from the frame 100 is smaller than the size of the guide parts 108 and 109, so that the guide parts 108 and 109 are first incorporated into the guide light main body 34. As a result, the incident portion 115 of the light guide plate 103 is automatically inserted into the light guide plate insertion portion 76 of the guide body 69. Further, the upper and lower light shielding portions 75 of the guide body 69 position the incident portion 115 of the light guide plate 103 so that the incident surface 119 of the light guide plate 103 faces the light source 72, and cover the upper and lower surfaces of the incident portion 115. ..
なお、誘導灯10を天井面に取り付ける場合には、天井面から引き出されている電線21を取付金具11の天井取付板部16の配線孔18に通し、天井取付板部16の取付孔19，20を通じてねじ25を天井面に螺着し、取付金具11を天井面に取り付ける。さらに、誘導灯本体34を取付金具11に取り付ける際には、取付金具11を挿通している電線21は誘導灯本体34の天井側切欠部46aに挿通配置される。
When the guide light 10 is mounted on the ceiling surface, the electric wire 21 pulled out from the ceiling surface is passed through the wiring hole 18 of the ceiling mounting plate portion 16 of the mounting bracket 11, and the mounting hole 19 of the ceiling mounting plate portion 16, A screw 25 is screwed onto the ceiling surface through 20 to attach the mounting bracket 11 to the ceiling surface. Further, when the guide light main body 34 is attached to the mounting bracket 11, the electric wire 21 that passes through the mounting bracket 11 is inserted and arranged in the ceiling-side cutout portion 46a of the guide light main body 34.
次に、誘導灯10の動作について説明する。
Next, the operation of the guide light 10 will be described.
外部電源の供給時には、電源回路部81の常時点灯回路により、外部電源を電源として光源72を点灯させ、かつ、電源回路部81の充電回路により、外部電源を電源として電池37を充電する。
When the external power is supplied, the light source 72 is turned on by using the external power source as the power source by the constant lighting circuit of the power source circuit unit 81, and the battery 37 is charged by the charging circuit of the power source circuit unit 81 using the external power source as the power source.
また、外部電源の停電時には、電源回路部81の非常時点灯回路により、電池37を電源として光源72を点灯させる。
In addition, when the external power supply fails, the emergency lighting circuit of the power supply circuit unit 81 lights the light source 72 using the battery 37 as a power supply.
そして、点灯する光源72の光は、導光板103の入射面119から入射部115に入射し、入射部115から湾曲部117および平板部116に導光され、湾曲部117および平板部116の前面側の発光面120から出射される。導光板103の発光面120から出射される光によって表示部102が照明される。
Then, the light of the light source 72 that is turned on is incident on the incident portion 115 from the incident surface 119 of the light guide plate 103, is guided from the incident portion 115 to the curved portion 117 and the flat plate portion 116, and the front surfaces of the curved portion 117 and the flat plate portion 116. The light is emitted from the side light emitting surface 120. The display unit 102 is illuminated by the light emitted from the light emitting surface 120 of the light guide plate 103.
また、図１３(a)には導光板103の正面図、図１３(b)には導光板103の底面図を示す。光源72の光が入射する入射面119から所定の範囲では、導光板103の内部から外面（空気層との界面）に入射する光の入射角が大きくなりやすく、導光板103の外面から外部に漏れる漏れ光ａが生じる。
13A shows a front view of the light guide plate 103, and FIG. 13B shows a bottom view of the light guide plate 103. In a predetermined range from the incident surface 119 where the light of the light source 72 is incident, the incident angle of the light incident from the inside of the light guide plate 103 to the outer surface (interface with the air layer) is likely to be large, and the light is incident from the outer surface of the light guide plate 103 to the outside. Leaking light a is generated.
ここで、図１４に導光板103が平板部116のみで構成されている場合の比較例を示す。図１４(a)には導光板103の正面図、図１４(b)には導光板103の底面図を示す。平板部116の下端の入射面119から光源72の光を入射すると、入射面119から所定の範囲に生じる漏れ光ａは発光面120の広い領域に存在することになり、この発光面120での漏れ光ａによって表示部102に輝度むらが生じやすい。
Here, FIG. 14 shows a comparative example in the case where the light guide plate 103 is composed of only the flat plate portion 116. 14A shows a front view of the light guide plate 103, and FIG. 14B shows a bottom view of the light guide plate 103. When light from the light source 72 is incident from the incident surface 119 at the lower end of the flat plate portion 116, the leaked light a generated in a predetermined range from the incident surface 119 exists in a wide area of the light emitting surface 120, and the light emitting surface 120 has a wide area. Luminance unevenness is likely to occur on the display unit 102 due to the leaked light a.
図１３に示す本実施形態では、比較例と同様に入射面119から所定の範囲で漏れ光ａが生じるが、その漏れ光ａは、主に入射部115から湾曲部117の領域で生じ、平板部116の領域つまり発光面120では少なくなるため、表示部102に輝度むらが生じるのを低減できる。
In the present embodiment shown in FIG. 13, leaked light a is generated in a predetermined range from the incident surface 119 similarly to the comparative example, but the leaked light a is mainly generated in the region from the incident portion 115 to the curved portion 117, and is flat. Since the area of the portion 116, that is, the light emitting surface 120 is small, it is possible to reduce the occurrence of uneven brightness in the display portion 102.
さらに、導光板103の入射部115が挿入されるガイド体69により、入射部115の端面である入射面119に交差する外面つまり上下面を覆うため、漏れ光ａの影響を低減できる。
Furthermore, since the guide body 69 into which the incident portion 115 of the light guide plate 103 is inserted covers the outer surface, that is, the upper and lower surfaces, which intersects the incident surface 119 which is the end surface of the incident portion 115, the influence of the leaked light a can be reduced.
また、寿命等で交換時期となった電池37は新しい電池37と交換する。図５に示すように、開閉カバー89を上方に移動させて電池着脱口62を開放し、電池収容部86に収容されている電池37を取り出し、電池37と電源部36とのコネクタ接続を解除する。また、新しい電池37を電源部36とコネクタ接続し、電池着脱口62から電池収容部86に収容し、開閉カバー89を下方に移動させて電池着脱口62を閉鎖する。
Also, the battery 37, which has reached the replacement time due to its life or the like, is replaced with a new battery 37. As shown in FIG. 5, the opening/closing cover 89 is moved upward to open the battery attaching/detaching port 62, the battery 37 accommodated in the battery accommodating portion 86 is taken out, and the connector connection between the battery 37 and the power source portion 36 is released. To do. In addition, a new battery 37 is connected to the power supply unit 36 by a connector, accommodated in the battery accommodating portion 86 through the battery attaching/detaching port 62, and the opening/closing cover 89 is moved downward to close the battery attaching/detaching port 62.
この電池37の交換時、誘導灯本体34の側面に電池着脱口62が設けられているため、表示ユニット13を外すことなく電池37を交換でき、しかも、開閉カバー89を移動させて電池着脱口62を開放しても、電池着脱口62から電池37が落下することはない。さらに、開閉カバー89は、誘導灯本体34の上下方向に移動して電池着脱口62を開閉可能とし、下方に移動して電池着脱口62を閉鎖するため、開閉カバー89の自重で電池着脱口62を自動的に閉じるとともに、開閉カバー89の閉じた状態が維持される。
When the battery 37 is replaced, the battery attaching/detaching port 62 is provided on the side surface of the guide light main body 34. Therefore, the battery 37 can be replaced without removing the display unit 13, and the opening/closing cover 89 can be moved to remove the battery attaching/detaching port. Even if 62 is opened, the battery 37 will not drop from the battery attaching/detaching port 62. Further, since the opening/closing cover 89 moves in the vertical direction of the guide light main body 34 to open/close the battery attaching/detaching port 62 and moves downward to close the battery attaching/detaching port 62, the opening/closing cover 89 is attached to the battery attaching/detaching port by its own weight. 62 is automatically closed and the closed state of the open/close cover 89 is maintained.
このように構成された本実施形態の誘導灯10では、取付金具11と誘導灯本体34とを分離しているため、取付金具11を先に被設置面に取り付け、この取付金具11に誘導灯本体34を取り付けることができ、例えば誘導灯本体34が小形の箱形であっても容易に取り付けることができ、施工性を向上できる。
In the guide light 10 of the present embodiment configured in this way, since the mounting bracket 11 and the main body 34 of the guide lamp are separated, the mounting bracket 11 is first mounted on the surface to be installed, and the guide lamp is attached to the mounting bracket 11.

The guide lamp body 34 can be attached to the mounting member 11 by passing it through the notch 46 of the lamp body 34.
誘導灯本体34内に配置される端子台38の接続孔95を、誘導灯本体34の切欠部46側である上方に向けているため、端子台38の接続孔95への電線21の接続を容易にでき、さらに、誘導灯本体34内に収容される電線21が煩雑にならず、小さい配線空間97に電線21を収めることができ、誘導灯10の小形化に対応できる。
Since the connection hole 95 of the terminal block 38 arranged in the guide light main body 34 is directed to the upper side which is the cutout portion 46 side of the guide light main body 34, the electric wire 21 is connected to the connection hole 95 of the terminal block 38. This is easy, and the electric wire 21 accommodated in the guide light main body 34 does not become complicated, and the electric wire 21 can be accommodated in the small wiring space 97, so that the guide light 10 can be downsized.
誘導灯本体34に表示ユニット13を取り付けることにより、表示ユニット13の保持部110によって取付金具11に誘導灯本体34を取り付けた状態で保持するため、誘導灯本体34が取付金具11から外れるのを防止できる。

Since the light a is mainly generated in the region from the incident portion 115 to the curved portion 117 and is small in the region of the flat plate portion 116, it is possible to reduce the occurrence of uneven brightness in the display unit 102.
導光板103の入射部115が挿入されるガイド体69により、入射部115の端面を光源72に対して位置決めするとともに、入射部115の端面である入射面119に交差する外面つまり上下面を覆うため、光源72の光が導光板103に効率的に入射できるとともに、漏れ光ａの影響を低減できる。
