As shown in FIGS. 1A to 1C, an emergency light 100 includes an instrument main body 1, a frame member 2, a light source 3, a first light distribution control means 4 provided facing the light source 3, a battery 5, and a light source. A lighting unit 6 for lighting 3, a notification means 7 described later, a second light distribution control means 9 provided opposite to the notification means 7, and a light source 3, a first light distribution control means 4, a notification means 7, a light source 3, and The light source unit 101 includes a substrate 8 on which the notification unit 7 is mounted and a second light distribution control unit 9. In this embodiment, the lighting device is preferably the emergency light 100 used at the time of a power failure. However, the lighting device is not limited thereto, and is applied to all indoor and outdoor lighting devices using a battery as a power source. Moreover, even if it is an embedded illuminating device, the illuminating device installed by other installation means, such as a direct attachment type and a ceiling-suspended type, may be sufficient.

  In this embodiment, “mounting” means that the light source, the notification means and the board are electrically and mechanically connected, for example, connected by a material such as solder, and “placement” Includes a lighting unit including a charging control means, a lighting control means, and the like on the substrate, and includes the meaning of mounting regardless of the presence or absence of electrical or mechanical connection.

  The instrument main body 1 is made of aluminum die casting and is configured as a cylindrical case member having an opening surface 1a at one end, and the battery 5 and the lighting unit 6 are housed inside the instrument main body 1.

  A frame member 2 having a function of a decorative frame for closing the installation hole 13 provided in the member to be installed 12 such as a ceiling is fitted to the opening surface 1a of the instrument main body 1 to block the periphery of the opening surface 1a. ing. The frame member 2 is made of aluminum die casting as in the case of the instrument main body 1, and has a substantially circular opening 2 a provided at the center of the frame member 2 for attaching a light source unit 101 to be described later, and a pull string 10 a for the inspection switch 10 to be described later. Inspection switch hole 2b, which is a slit-like opening provided in an intermediate portion between the central portion and the outer periphery of the frame member 2 and a frame portion 2c having a substantially L-shaped cross section. The frame portion 2c is fitted into the opening surface 1a of the instrument main body 1, and is supported and fixed by a fixing means such as a screw (not shown) from the side.

  The support 11 is for supporting the instrument main body 1 on an installation member 12 such as a ceiling, and is composed of two substantially L-shaped leaf springs formed by pressing a stainless steel plate material. The part is positioned on the outer surface of the instrument body 1 so as to face the radial direction and is fixed with screws or the like.

  The support 11 made of this leaf spring is inserted into the installation hole 13 of the installation target member 12 such as the ceiling surface together with the instrument main body 1 while being bent inward from each other. After returning to the above state, the instrument body 1 is pressed against the inner surface of the installation hole 13, and the instrument body 1 is fixed to the installation member 12 by the pressure contact force. In the case of removal, the reverse operation is performed.

  As shown in FIG. 1, the emergency light 100 is, for example, a small-sized illumination that is driven by an AC 100V having a diameter 2 of the frame member 2 of about 90 to 100 mm, a diameter D2 of the instrument body 1 of about 85 mm, and a power consumption of 13 W. It may be configured as a device. At this time, as described above, the instrument body 1 has a small diameter dimension D2 of the instrument body 1 of only about 85 mm and a height h from the surface 12a of the installation member to the end of the instrument body 1 of about 65 mm. Therefore, the installation hole 13 is small, and the construction becomes easy.

  The battery 5 is housed in a battery case 5a, and is positioned in a cylindrical case of the instrument main body 1 above a light source unit 101 to be described later, and a case support member provided on the inner side of the instrument main body 1 of the frame member 2. It is supported and disposed. The case support member is substantially the case support member mounting portion 2d that contacts the bottom surface of the battery case 5a, that is, the surface located on the frame member 2 side, and the side surface of the battery case 5a, that is, an axis that connects the positive electrode and the negative electrode of the battery 5. A case support member guide portion 2g provided on the inner side of the instrument body 1 of the frame member 2 is provided in parallel with the surface provided on the battery case 5a.

  In the battery case 5a, a plurality of batteries 5 may be provided as an assembled battery as shown in FIG. 1, or a plurality of batteries may be stacked and covered with an outer shell. Good. The battery case 5a may be made of a metal such as stainless steel or aluminum, or may be made of a nonflammable synthetic resin.

  The battery case 5 a is provided with a current collector (not shown) and a connection terminal (not shown) for electrically connecting the current collector and the lighting unit 6. As shown in FIG. 1A and FIG. 1B, the current collector serves to electrically connect the plurality of batteries 5 when the plurality of batteries 5 are provided in the battery case 5a. Is.

  The case support member mounting portion 2d is provided on the inner side of the instrument main body 1 of the frame member 2, and supports the battery case 5a inside the instrument main body 1 by supporting the bottom of the battery case 5a. As shown in FIG. 2B, the case support member placement portion 2d is formed in an arc shape such that a contact portion with the bottom portion of the battery case 5a surrounds the opening 2a. Even when the surface on the inner side of the instrument main body 1 of the light source unit 101 to be described later and the surface on the inner side of the instrument main body 1 of the frame member 2 are flush with each other, the case support member mounting portion 2d is provided on the frame member 2. Is preferred. Since the space is formed on the surface of the frame member 2 on the inner side of the instrument body 1 and the bottom surface of the battery case 5a by the case support member mounting portion 2d, the heat generated from the battery 5 is efficiently transferred to the battery 5 and the battery case 5a. The battery 5 can be prevented from being deteriorated by heat. Further, heat generated from the battery 5 reaches the surface of the frame member 2 on the surface 12a side of the installation member by conducting heat through the bottom surface of the battery case 5a and the case support member mounting portion 2d, and is generated from the battery 5. The released heat can be released to the outside of the emergency light 100.

  The case support member guide portion 2g is formed on the inner side of the instrument body 1 of the frame member 2 so as to surround the side surface of the battery case 5a. As shown in FIG. 1 and FIG. 2, when the side surface of the battery case 5a is formed of an arcuate curved surface and a plane connected to the curved surface in a cross section perpendicular to the axis connecting the positive electrode and the negative electrode of the battery 5, In order to stably support the battery case 5a on the frame member 2, it is preferable that the case support member guide portion 2g is provided so as to face both the curved side surface and the planar side surface.

  The height of the case support member guide portion 2g, that is, the distance from the inner surface of the frame member 2 to the end of the case support member guide portion 2g is 1 / height of the battery case 5a. About 3 is preferable from the viewpoint of removing the frame member 2 of the battery case 5a. It is because it will become difficult to take out battery case 5a from a case support member when the upper surface of battery case 5a may fall below the edge part of the other end side of the connection part with frame member 2 of case support member guide part 2g.

  As shown in FIG. 2B, the case supporting member guide portion 2g is preferably formed of a plurality of separate side walls, rather than being formed by one closed plane. When the case support member guide portion 2g is formed by a side wall formed by one closed plane, when the battery case 5a is separated from the frame member 2, air flows into the space formed by the bottom surface of the battery case 5a and the case support member. This is because the inside of the space becomes negative pressure and it is difficult to separate the battery case 5a from the frame member 2. In addition, if the case support member guide portion 2g is formed by a side wall formed by one closed plane, heat generated from the battery 5 is hardly released, and the battery 5 may be deteriorated.

  Therefore, since the battery case 5a is supported by the case support member, the battery case 5a can be taken out of the instrument body 1 together with the frame member 2 by removing the frame member 2. Further, since the side surface of the battery case 5a is supported by the case support member guide portion 2g, it is possible to prevent the battery case 5a from falling out of the frame member 2 when the frame member 2 is detached from the instrument body 1 and attached.

  The lighting unit 6 for lighting the light source 3 by the battery 5 is housed in the lighting unit housing 6d, and is positioned above the light source unit 101 described later in the cylindrical case of the fixture body 1 and supported by the support member 1b. Arranged and stored. In the lighting unit housing 6d, there is a charging control means 6a for charging the battery 5 with an external power source and a lighting unit substrate 6c for constituting a lighting control means 6b for lighting the light source 3 using the battery 5 as a power source. A mounting surface 6e for mounting electronic parts and the like necessary for configuring the means 6a and the lighting control means 6b is arranged so as to be substantially parallel to the light emission direction of the light source 3.

  On the back side of the mounting surface 6e of the lighting unit substrate 6c, a heat dissipation member (not shown) is provided on the mounting surface 6e of the lighting unit substrate 6c in order to release heat generated from the lighting unit substrate 6c to the outside of the lighting unit housing 6d. It may be provided so as to be in close contact with the back side surface and capable of conducting heat. The heat radiating member may be provided in close contact with the flat portion of the lighting unit housing 6d in the space between the lighting unit housing 6d and the battery case 5a. At this time, from the viewpoint of heat dissipation efficiency, it is preferable that the back side surface of the mounting surface 6e of the lighting unit substrate 6c and the heat dissipation member are provided so as to be able to conduct heat via the flat portion of the lighting unit housing 6d.

  The inspection switch 10 is mounted on the mounting surface 6e. The inspection switch 10 is used when the emergency light 100 is inspected according to laws and regulations. For example, when the inspection switch 10 is operated, the power charged in the battery 5 is supplied. It is for supplying to the light source 3 and confirming whether the light source 3 lights normally. The inspection switch 10 is provided with a pull string 10a as an operation unit. A check switch through hole 2b is formed in the frame member 2 at a position opposite to the tip of the pull string 10a, and a pull string 10a as an operation part of the check switch 10 is inserted so that the tip of the pull string 10a is framed. It protrudes from the outer surface of the member 2, that is, the lower surface of the frame member 2 in this embodiment, and is configured so that the inspection switch 10 can be operated from the outside of the emergency light 100. Thereby, the charge control means 6a, the lighting control means 6b, and the inspection switch 10 are configured on a common lighting unit board 6c. In order to expose the drawstring 10a to the outside of the emergency light 100, the support member 1b is provided with a hole 1c facing the inspection switch through hole 2b.

It is preferable from the viewpoint of operability. Further, since the light source unit 101 and the lighting unit 6 are connected by an electrical connection means, specifically, a connector and an electric wire, it is possible to reduce applying a mechanical load to the connector and the electric wire when the light source unit 101 is attached and detached. Therefore, connection means by fitting and turning is preferable. When this connection means is used, it is preferable that the operation angle during rotation is as small as possible. In addition, you may make | form by providing an external thread part and an internal thread part in the outer periphery of the glass lens 14, and the inner periphery of the opening part 2a.

The 1st light distribution control means 4 and the 2nd light distribution control means 9 are comprised by forming a convex part in the light emission direction of the light source 3 and the alerting | reporting means 7 in the output surface 14c.

  After the glass lens opening 14 a is provided with the substrate 8, the remaining space of the glass lens opening 14 a is sealed by the closing member 15. In addition, the board | substrate 8 is fixed so that it may not move within the glass lens opening part 14a by fitting the inner peripheral part of the glass lens opening part 14a, and the outer peripheral part of the closure member 15 without gap. If the substrate 8 may move within the glass lens opening 14a, the positional relationship between the light source 3, the first light distribution control means 4, the notification means 7, and the second light distribution control means 9 is shifted, which is desired. Therefore, it is desirable that the closing member 15 be fixed to the glass lens 14 by a fixing means that cannot be removed from the glass lens opening 14a.

  The closing member 15 may be provided so that the back side surface 8 b opposite to the mounting surface of the substrate 8 is in close contact with the surface of the closing member 15.

That is, the second light distribution control means 9 is provided on the glass lens 14 so that the second light distribution control means 9 does not enter the light source emission range 31.

  Note that, as shown in the cross-sectional view of the light source unit 103 in FIG. 5, the first light distribution control unit 4 and the second light distribution control unit 9 may be formed only from the concave portions formed in the incident surface 14 b. At this time, d1 and d2 are respectively the distance from the mounting surface 8a of the substrate 8 to the concave end portion of the first light distribution control means 4, and the distance from the mounting surface 8a to the concave end portion of the second light distribution control means 9. Determined. In this case, d1 is formed to be larger than d2.

  Further, the first light distribution control means 4 and the second light distribution control means 9 may have different shapes. For example, the 1st light distribution control means 4 may consist only of the convex part formed in the output surface 14c, and the 2nd light distribution control means 9 may consist only of the recessed part formed in the incident surface 14b.

  Next, the circuit configuration and operation of the emergency light 100 will be described with reference to FIG.

  When the power failure detection means 6g detects that the voltage of the external power supply 16 applied to the power supply terminal block 17 is equal to or lower than a predetermined value for a predetermined time, the power failure detection signal is turned on by the lighting control means 6b. Or it is given to the lighting control part 6f. Note that the power terminal block 17 may be provided outside the fixture body 1 or inside the fixture body 1 and outside the lighting unit housing 6d or inside the lighting unit housing 6d. In any case, when removing the battery 5 and the battery case 5a, the battery 5 and the battery case 5a can be removed without removing the lighting unit 6 and the lighting unit housing 6d, that is, the battery 5 and the battery case 5a. The power terminal block 17 is provided at a position that does not hinder the removal.

  The charging control means 6a converts the alternating current of the external power supply 16 into a predetermined direct current, supplies power to the battery 5, and charges it. For example, you may comprise so that the alerting | reporting means 7 will light when the battery 5 will be in the state of full charge. An emergency lighting circuit 6 i is connected to the battery 5.

  The emergency lighting circuit 6i is a circuit for lighting the light source 3 with a constant current using the battery 5 as a power source in the event of a power failure of the external power source 16. The emergency lighting circuit 6i is connected to the light source 3 through the lighting control unit 6f.

  In the event of an emergency such as a power failure of the external power supply 16, the lighting control unit 6f receives a power failure detection signal from the power failure detection means 6c that detects the power failure, and turns on the light source 3 for a predetermined time or more by the emergency lighting circuit 6i. .

An inspection circuit 6h is connected to the power failure detection means 6g. An inspection switch 10 is connected to the inspection circuit 6h. When the pull string 10a of the inspection switch 10 is pulled, the inspection switch 10 connects the battery 5 and the lighting control means 6b. Thereby, it is confirmed that the light source 3 is turned on at the time of a power failure.
The operation of the notification means 7 will be described.

  The notification means 7 is turned on when the battery 5 is charged by the charging control means 6a of the lighting unit 6 using the electric power supplied from the external power source 16, and the battery 5 is maintained at substantially full charge. In addition, when the light source 3 is connected to the lighting control unit 6f or the lighting unit 6 and can be turned on by the power supplied from the battery 5, the notification unit 7 is turned on. Informing means 7 for informing the state of the battery 5 and the light source 3 may be provided corresponding to the battery 5 and the light source 3, respectively. In addition, when only one notification means 7 is provided in the light source unit 101 or the like, the battery 5 is charged, the battery 5 is maintained at a substantially full charge, and the light source 3 is connected to the lighting control unit 6f or the lighting unit 6. Lights when connected and in a state that can be lit by power supplied from the battery 5.

  Moreover, you may alert | report the alerting | reporting means 7 by displaying that it is in an inspection operation in a lighting state. For example, when a signal for starting an inspection is input to the inspection circuit 6h by the inspection switch 10, the notification unit 7 notifies that the lighting unit 6 is performing the inspection operation according to the lighting state. In this case, the notification means 7 may be turned on, or the inspection operation may be notified outside the emergency light 100 by a blinking state.

  Note that the notification means 7 may be configured to notify not only the inspection operation but also the inspection result. At this time, it is preferable from the viewpoint of visibility that the lighting state of the notification means 7 differs depending on whether there is an abnormality in the inspection result of the battery 5 and whether there is an abnormality in the inspection result of the light source 3.

  As the notification means 7, the notification means 7 that notifies that the inspection operation is being performed is displayed in a lighting state, and the battery 5 is connected to the battery 5 by the charge control means 6 a of the lighting unit 6 using the power supplied from the external power source 16. The charging means 7 is turned on when the battery 5 is substantially fully charged, and the light source 3 is connected to the lighting control unit 6f or the lighting unit 6 and is lit by the power supplied from the battery 5. Informing means 7 that is turned on when the battery 5 and the light source 3 are provided is provided for the notifying means 7 for notifying the charging state of the battery 5 and the notifying means 7 for notifying the connection state of the light source 3, respectively. Each may be notified.

  The effect of the first embodiment will be described.

  The light source 3, the light source unit 101, and the like are disposed with a gap with respect to the lighting unit 6, and are detachably disposed with respect to the frame member 2. And can be removed from the frame member 2.

  The light source 3 provided in the light source unit 101 or the like is held by the substrate 8, the stepped part 14 d or the incident surface 14 b, and the closing member 15 inside the glass lens opening 14 a of the light source unit 101 or the like. A desired light distribution characteristic for the light source 3 and the notification unit 7 can be obtained without causing a deviation in the positional relationship between the light distribution control unit 4 or the positional relationship between the notification unit 7 and the second light distribution control unit 9. .

  Since the battery 5 and the battery case 5a are only supported by the case support member provided in the frame member 2 inside the instrument body 1, the battery 5 and the battery 5 are removed by removing the frame member 2 from the instrument body 1. The case 5a can be taken out of the instrument body 1 together with the frame member 2.

  Since the space is formed on the surface of the frame member 2 on the inner side of the instrument body 1 and the bottom surface of the battery case 5a by the case support member mounting portion 2d, the heat generated from the battery 5 is efficiently transferred to the battery 5 and the battery case 5a. The battery 5 can be prevented from being deteriorated by heat. Further, heat generated from the battery 5 reaches the surface of the frame member 2 on the surface 12a side of the installation member by conducting heat through the bottom surface of the battery case 5a and the case support member mounting portion 2d, and is generated from the battery 5. The released heat can be released to the outside of the emergency light 100, and deterioration of the battery 5 due to heat can be suppressed.

  When the side surface of the battery case 5a is formed of an arcuate curved surface and a plane connected to the curved surface in a cross section orthogonal to the axis connecting the positive electrode and the negative electrode of the battery 5, the curved side surface and the planar side surface The battery case 5a can be stably supported on the frame member 2 by providing the case support member guide portion 2g so as to face both of them.

  The height of the case support member guide portion 2g, that is, the distance from the inner surface of the frame member 2 to the end of the case support member guide portion 2g is about 1/3 of the height of the battery case 5a. Thus, the battery case 5a can be easily detached from the case support member and the frame member 2.

  When the battery case 5a is separated from the frame member 2 by forming the case support member guide portion 2g from a plurality of separate side walls instead of being formed by a single closed plane, the bottom surface of the battery case 5a and the case Air can easily flow into the space formed by the support member, the interior of the space does not become negative pressure, and the battery case 5a can be easily separated from the frame member 2. In addition, by forming the case support member guide portion 2g from a plurality of separate side walls, heat generated from the battery 5 is easily released, and heat generated from the battery 5 is efficiently removed from the battery 5 and the battery case 5a. It is possible to suppress deterioration of the battery 5 due to heat.

  Since the side surface of the battery case 5a is supported by the case support member guide portion 2g, when the frame member 2 is detached from the instrument body 1 and attached, it can be taken out of the instrument body 1 together with the frame member 2. It can be prevented from falling off.

  The first light distribution control means 4 provided in the light source unit 101 is such that the distance from the mounting surface 8a of the substrate 8 to the end of the light distribution direction of the light source 3 of the first light distribution control means 4 is the second light distribution. Since the distance from the mounting surface 8a of the control means 9 to the end of the light emission direction of the notification means 7 of the second light distribution control means 9 is larger than the distance, the light emitted from the first light distribution control means 4 is notified. Or the 2nd light distribution control means 9 does not obstruct | occlude.

  The first light distribution control unit 4 provided in the light source unit 102 and the light source unit 103 is a light source of the first light distribution control unit 4 from the end of the recess in the light emission direction of the light source 3 of the first light distribution control unit 4. The distance from the light source 3 of the second light distribution control means 9 to the light emitting direction of the light source 3 of the second light distribution control means 9 is from the end of the recess to the light emission direction of the notification means 7 of the second light distribution control means 9. Since it is larger than the distance to the end with respect to the direction, the notification means 7 or the second light distribution control means 9 does not block the light emitted from the first light distribution control means 4.

  (Embodiment 2) An emergency light 200 according to a lighting apparatus of a second embodiment of the present invention will be described with reference to the drawings.

And a light source unit 201 having a light source 3, a first light distribution control unit 4, a notification unit 7, a second light distribution control unit 9, and a substrate 28.

  The frame member 2 projects the first light distribution control means 4 from the surface of the frame member 2, and the light source 3 is provided at the center of the frame member 2 in order to make the light emitted from the light source 3 visible from the outside of the emergency light 200. And a substantially circular first light distribution control means hole 2f provided opposite to the first light distribution control means 4.

  The battery 5 is housed in a battery case 5a and is positioned above a light source unit 201 (described later) in a cylindrical case of the instrument main body 1 and is attached to a case support member provided on the inner side of the instrument main body 1 of the frame member 2. It is supported and disposed. From the viewpoint of reducing the size of the emergency light 200, the battery 5 is provided along the periphery of the instrument body 1, and the battery case 5a is disposed in a direction orthogonal to the axis connecting the positive electrode and the negative electrode of the battery 5 so as to include the battery case 5a. The cross section is preferably formed in a substantially U shape. Thus, by arranging the battery 5 in a space other than the light source unit 201 and the lighting unit 6 to be described later, the emergency light 200 can be reduced in size, and the light source 3, the lighting unit 6 and the battery 5 can be reduced. The influence on each component by the heat generated from each can be reduced.

  As shown in FIG. 8B, the case support member mounting portion 2d is formed in an arc shape so that a contact portion with the bottom portion of the battery case 5a surrounds the first light distribution control means hole 2f. Is done. Even when the surface on the inner side of the instrument body 1 of the light source unit 201 to be described later and the surface on the inner side of the instrument body 1 of the frame member 2 are flush with each other, the case support member mounting portion 2d is provided on the frame member 2. Is preferred. Since the space is formed on the surface of the frame member 2 on the inner side of the instrument body 1 and the bottom surface of the battery case 5a by the case support member mounting portion 2d, the heat generated from the battery 5 is efficiently transferred to the battery 5 and the battery case 5a. The battery 5 can be prevented from being deteriorated by heat. Further, heat generated from the battery 5 reaches the surface of the frame member 2 on the surface 12a side of the installation member by conducting heat through the bottom surface of the battery case 5a and the case support member mounting portion 2d, and is generated from the battery 5. The released heat can be released to the outside of the emergency light 200.

  The case support member guide portion 2g is formed on the inner side of the instrument body 1 of the frame member 2 so as to surround the side surface of the battery case 5a. As shown in FIGS. 7 and 8, when the side surface of the battery case 5 a is substantially U-shaped in a cross section perpendicular to the axis connecting the positive electrode and the negative electrode of the battery 5, It is preferable that the case support member guide portion 2g is provided so as to face both of them in order to stably support the battery case 5a on the frame member 2.

  The lighting unit 6 that turns on the light source 3 with the battery 5 is housed in a lighting unit housing 6d provided inside the fixture body 1 and placed on a substrate 28 on which the light source 3 is mounted. The substrate 28 is supported by the support member 6j and disposed and accommodated in the lighting unit housing 6d. Inside the lighting unit housing 6d, a charging control means 6a for charging the battery 5 by the external power source 16 shown in FIG. 6 and a lighting control means 6b for lighting the light source 3 using the battery 5 as a power source are mounted on the substrate 28. It is mounted on the back side surface 28b which is the back side of the mounting surface 28a.

  A heat radiating member (not shown) is provided on the rear side surface 28b of the substrate 28 in order to release heat generated from the lighting unit 6 or the light source 3 to the outside of the lighting unit housing 6d or the instrument body 1. It may be provided in close contact with the inside of the lighting unit housing 6d so as to be able to conduct heat. From the viewpoint of reducing the number of components of the emergency light 200, the support member 6c for supporting the substrate 28 is made of a material having excellent heat conduction such as metal inside the lighting unit housing 6d, and the lighting unit 6 or the light source You may add the function as a heat radiating member which radiates the heat | fever generate | occur | produced from 3 grade | etc., By heat conduction and a thermal convection.

  Further, when the substrate 28 is supported by the support member 6c, if the support member 6c is sufficiently separated from the wiring pattern on the substrate 28, for example, the support member 6c and the lighting unit housing 6d or It is not particularly necessary to consider the insulation distance from the appliance main body 1, and it is particularly suitable when the lighting unit housing 6d or the appliance main body 1 is made of metal. In this case, it is preferable that the support member 6c is made of an insulating material, for example, a resin material, rubber, or the like in consideration of the insulating properties, and a structure that improves heat dissipation can be realized without causing electrical problems. Is possible. When an insulating material is used for the support member 6c, the support member 6c causes heat generated from the lighting unit 6 or the light source 3 or the like to be external to the lighting unit housing 6d or the instrument body 1 by heat convection and heat conduction. It can have a function as a heat radiating member for radiating heat.

  Further, the support member 6 c has a function for maintaining desired light distribution control defined for the instrument main body 1 and the frame member 2 of the light source unit 201. When the support member 6c is not used, the substrate 28 is supported only by the glass lens 24 with respect to the lighting unit housing 6d. Therefore, the light source unit 201 is moved to a position relative to the instrument body 1 by removing the frame member 2 or the like. There is a possibility that a deviation occurs, and desired light distribution control for the instrument body 1 and the frame member 2 of the light source unit 201 cannot be obtained. Since the support member 6c supports the substrate 28 in the lighting unit housing 6d, the substrate 28 is not supported only by the glass lens 24, and the fixture body 1 and the frame of the light source unit 201 can be removed even when the frame member 2 is removed. Desired light distribution control for the member 2 can be maintained.

  The inspection switch 10 is mounted on the back side surface 28b.

The first light distribution control means 4 and the frame member 2 are provided so as to be separable. The first light distribution control means 4 is provided on a glass lens 24 serving as a base.

  The light source 3 is composed of a semiconductor light emitting element. In this embodiment, the light source 3 is composed of a light emitting diode. In this embodiment, one light emitting diode is prepared, and the frame member 2 is formed on the mounting surface 28a of the disk-shaped substrate 28. A substantially circular first light distribution control means hole 2f formed in the central portion is mounted and supported so as to face the vicinity of the substantial center. The notification means 7 displays, for example, the state of charge of the battery by a lighting state, and is composed of a semiconductor light emitting element such as a light emitting diode. The notification means 7 is disposed so as to face the periphery of the first light distribution control means hole 2f. That is, it arrange | positions so that the circumference | surroundings of the glass lens 24 may be faced, and it is arrange | positioned in the position which does not block the light radiated | emitted from the 1st light distribution control means 4. FIG.

  As shown in FIG. 9A, the glass lens 24 has a glass lens recess 24 a at a position facing the light source 3 and the notification means 7. An incident surface 24b is formed on the bottom surface of the glass lens recess 24a. The substrate 28 is provided in the glass lens recess 24a so that the mounting surface 28a on which the light source 3 and the notification means 7 are mounted faces the incident surface 24b.

  As shown in FIG. 9A, the first light distribution control means 4 and the second light distribution control means 9 face the light source 3 and the notification means 7 respectively, and the first light distribution control means hole of the frame member 2. 2f and the second light distribution control means hole 2e. The light emitted from the light source 3 and the notification means 7 enters the glass lens 24 from the incident surface 24b, and the first light distribution control means 4 via the first light distribution control means 4 and the second light distribution control means 9. The light is emitted into the space from the emission surface 24c, which is the end of the second light distribution control means 9 in the light emission direction. The 1st light distribution control means 4 and the 2nd light distribution control means 9 are comprised by forming a convex part in the light emission direction of the light source 3 and the alerting | reporting means 7 in the output surface 24c.

  The glass lens 24 is fixed to the substrate 28 by providing a fixing means such as an adhesive at the contact portion 24d of the mounting surface 28a of the substrate 28. If the glass lens 24 moves with respect to the substrate 28, the positional relationship between the light source 3, the first light distribution control means 4, the notification means 7, and the second light distribution control means 9 is shifted. Since optical control may not be possible, it is desirable that the glass lens 24 be firmly fixed to the substrate 28.

  The heat radiating means 25 is provided such that the back side surface 28 b of the substrate 28 is in close contact with the surface of the heat radiating means 25. As described above, the heat dissipating means 25 is disposed so as to face the light source 3 and the notifying means 7 through the substrate 28, so that the heat released by the light emission from the light source 3 or the notifying means 7 causes the heat dissipating means 25. Via the light source unit 201. The heat dissipating means 25 is preferably formed from a material having a high thermal conductivity such as copper or aluminum, a metal material, or the like.

  The first light distribution control means 4 and the second light distribution control means 9 are formed from the mounting surface 28a of the substrate 28 with respect to the light emission direction of the light source 3 of the first light distribution control means 4 and the second light distribution control means 9. As shown in FIG. 9A, the distance to the end of the notification means 7 in the light emission direction is set to be d1 and d2, respectively. Then, d1 is formed to be larger than d2.

  In the light source part 201, the case where the 1st light distribution control means 4 and the 2nd light distribution control means 9 are arrange | positioned only in the output surface 24c of the glass lens 24 by forming a convex part in the light emission direction was shown. However, the formation of the first light distribution control means 4 and the second light distribution control means 9 is not limited to this.

  FIG. 10 shows a cross-sectional view of the light source unit 202 as a modification of the first light distribution control means 4 and the second light distribution control means 9.

  Unlike the light source unit 201, the light source unit 202 does not include the glass lens recess 14a in the glass lens 24, and the substrate 28 is placed so that the mounting surface 28a of the substrate 28 and the incident surface 24b of the glass lens 24 of the light source unit 201 are in contact with each other. The first light distribution control unit 4 and the second light distribution control unit 9 are disposed on both the incident surface 24b and the emission surface 24c that are disposed in the glass lens recess 24a and that face the light source 3 and the notification unit 7, respectively. It has a special feature.

  The glass lens 24 of the light source unit 202 is provided with the first light distribution control means 4 and the second light distribution control means 9 by forming a recess in the light emission direction on the incident surface 24b, and on the emission surface 24c. In the same manner as the glass lens 24 of the light source unit 201, the first light distribution control means 4 and the second light distribution control means 9 are arranged by forming convex portions in the light emitting direction. In the glass lens 24 of the light source unit 202, the first light distribution control means 4 and the second light distribution control means 9 are a concave portion formed on the incident surface 24b and a convex portion formed on the output surface 24c.

  At this time, d1 may be a distance from the mounting surface 28a of the substrate 28 to the end of the convex portion of the first light distribution control means 4, or the first light distribution control from the end of the concave portion of the first light distribution control means 4. It is good also as the distance to the convex part edge part of the means 4. Similarly for d2, d2 may be the distance from the mounting surface 28a of the substrate 28 to the end of the convex portion of the second light distribution control means 9, or from the end of the concave portion of the second light distribution control means 9. It is good also as the distance to the convex part edge part of 2 light distribution control means 9. FIG. In either case, d1 is formed to be larger than d2.

  The light source emission range 41 indicates the range of light emitted from the light source 3. As shown in FIG. 10, the second light distribution control means 9 is provided so as not to block the light emitted from the light source 3. That is, the second light distribution control means 9 is provided on the glass lens 24 so that the second light distribution control means 9 does not enter the light source emission range 41.

  As shown in the cross-sectional view of the light source unit 203 in FIG. 11, the first light distribution control unit 4 and the second light distribution control unit 9 are only concave portions formed on the incident surface 24 b of the glass lens 24 of the light source unit 201. May be formed. At this time, d1 and d2 are respectively the distance from the mounting surface 28a of the substrate 28 to the concave end portion of the first light distribution control means 4, and the distance from the mounting surface 28a to the concave end portion of the second light distribution control means 9. Determined. In this case, d1 is formed to be larger than d2.

  Further, the first light distribution control means 4 and the second light distribution control means 9 may have different shapes. For example, the 1st light distribution control means 4 may consist only of the convex part formed in the output surface 24c, and the 2nd light distribution control means 9 may consist only of the recessed part formed in the incident surface 24b.

  The effect of the second embodiment will be described.

  By placing the charge control means 6a and the lighting control means 6b on the substrate 28 on which the semiconductor light emitting element of the light source 3 is mounted, the lead wire between the light source 3 and the lighting unit 6 can be made unnecessary. Further, since there is no wiring between the light source 3 and the lighting unit 6, non-lighting of the light source 3 due to deterioration of the lead wire or the like can be reduced. Further, since there is no lead wire between the light source 3 and the lighting unit 6, it is possible to prevent the light source 3 from being unlit due to a defective lead wire between the light source 3 and the lighting unit 6 during assembly or construction in the manufacture of the emergency light 200.

  The glass lens 24 provided in the light source unit 201 and the like has the positional relationship between the optical axis oo of the light source 3 and the central portion of the first light distribution control unit 4 fixed by the fixing unit. A desired light distribution characteristic for the light source 3 and the notification unit 7 can be obtained without causing a deviation in the positional relationship between the light distribution control unit 4 or the positional relationship between the notification unit 7 and the second light distribution control unit 9. .

  Since the battery 5 and the battery case 5a are only supported by the case support member mounting portion 2d provided in the frame member 2 inside the instrument body 1, by removing the frame member 2 from the instrument body 1, The battery 5 and the battery case 5a can be taken out of the instrument body 1.

  Since the space is formed on the surface of the frame member 2 on the inner side of the instrument body 1 and the bottom surface of the battery case 5a by the case support member mounting portion 2d, the heat generated from the battery 5 is efficiently transferred to the battery 5 and the battery case 5a. The battery 5 can be prevented from being deteriorated by heat. Further, heat generated from the battery 5 reaches the surface of the frame member 2 on the surface 12a side of the installation member by conducting heat through the bottom surface of the battery case 5a and the case support member mounting portion 2d, and is generated from the battery 5. The released heat can be released to the outside of the emergency light 200, and deterioration of the battery 5 due to heat can be suppressed.

  When the shape of the side surface of the battery case 5a in the cross section orthogonal to the axis connecting the positive electrode and the negative electrode of the battery 5 is substantially U-shaped, the case support member guide faces both of the substantially U-shaped side surfaces. By providing the portion 2g, the battery case 5a can be stably supported on the frame member 2.

  The height of the case support member guide portion 2g, that is, the distance from the inner surface of the frame member 2 to the end of the case support member guide portion 2g is about 1/3 of the height of the battery case 5a. Thus, the battery case 5a can be easily detached from the case support member and the frame member 2.

  When the battery case 5a is separated from the frame member 2 by forming the case support member guide portion 2g from a plurality of separate side walls instead of being formed by a single closed plane, the bottom surface of the battery case 5a and the case Air can easily flow into the space formed by the support member, the interior of the space does not become negative pressure, and the battery case 5a can be easily separated from the frame member 2. In addition, by forming the case support member guide portion 2g from a plurality of separate side walls, heat generated from the battery 5 is easily released, and heat generated from the battery 5 is efficiently removed from the battery 5 and the battery case 5a. It is possible to suppress deterioration of the battery 5 due to heat.

  Since the side surface of the battery case 5a is supported by the case support member guide portion 2g, when the frame member 2 is detached from the instrument body 1 and attached, it can be taken out of the instrument body 1 together with the frame member 2. It can be prevented from falling off.
