  By the way, in the conventional example described in Patent Document 1, two fluorescent lamps are used for both regular illumination and emergency illumination. In order to ensure the prescribed illuminance and lighting time during emergency illumination, the capacity of the storage battery Must be increased. However, if the capacity of the storage battery is increased, the space occupied by the storage battery also increases, so that the emergency light unit portion becomes larger.

  Therefore, it is conceivable to use a light source that consumes less power than a fluorescent lamp (a light source that is smaller than a fluorescent lamp) as a light source for emergency illumination in a luminaire that can be used for both ordinary illumination and emergency illumination. In this case, it is necessary to control the light distribution of the light emitted from the light source of the emergency illumination using an optical component such as a lens in order to ensure the same illumination range for the normal illumination and the emergency illumination. .

  However, in order to reduce the size of the instrument body, when the light source for normal illumination (for example, a fluorescent lamp) and the light source for emergency illumination are arranged close to each other, the light path of the light source for normal illumination becomes the light source for emergency illumination. There is a risk that the irradiation range will be narrowed due to obstruction.

  This invention is made | formed in view of the said subject, and aims at making it difficult to narrow the irradiation range of regular illumination.

  The lighting apparatus of the present invention includes a normal light source unit that is powered and lit by a normal power source, an emergency photoelectric unit that is powered and lit by an emergency power source during a power failure of the normal power source, the normal light source unit, and the emergency light source An instrument body that supports the units so that they are arranged side by side, and the emergency light source unit includes a light source, an optical component that controls light distribution of light emitted from the light source, and the light source and the optical component.

On the other hand, in the lighting fixture of the present embodiment, the lens 31 is accommodated in the housing 32 while being shifted from the center of the housing 32 in the direction away from the regular light source unit 2. For this reason, the light emitted from the regular light source unit 2 is not easily blocked by the lens 31 of the emergency light source unit 3. As a result, the lighting fixture of this embodiment can make it difficult to narrow the irradiation range of regular illumination.

Therefore, the lighting fixture of this embodiment can accommodate the operation member 342 and the display unit 35 in the housing 32 while suppressing an increase in the size of the housing 32 of the emergency light source unit 3.

  As described above, the lighting fixture of the present embodiment includes the regular light source unit 2 that is powered on from the regular power source and is turned on, and the emergency light source unit 3 that is fed from the emergency power source (storage battery 38) and is lit when the regular power source is powered off. Is provided. Moreover, the lighting fixture of this embodiment is provided with the fixture main body 1 which supports the regular light source unit 2 and the emergency light source unit 3 so that it may be located side by side. The emergency light source unit 3 includes a light source (emergency LED module 30), an optical component (lens 31) that controls light distribution of light emitted from the light source, and a housing 32 that houses the light source and the optical component. . The housing | casing 32 is comprised so that at least one part of an optical component may protrude from the surface. The optical component is accommodated in the casing 32 while being shifted in a direction away from the regular light source unit 2 with respect to the center of the casing 32.

  The lighting fixture of the present embodiment is configured as described above, and the light emitted from the ordinary light source unit 2 is not easily blocked by the optical component (lens 31) of the emergency light source unit 3, so the irradiation range of the ordinary illumination is narrowed. It can be made difficult.

  Moreover, in the lighting fixture of this embodiment, the emergency light source unit 3 has the display part 35 which displays an own operation state, and the operation part (operation member 342) operated in order to start inspection operation | movement. Is preferred. Moreover, it is preferable that the housing | casing 32 is comprised so that the display part 35 and the operation part (operation member 342) may be arrange | positioned in the position near the common light source unit 2 rather than an optical component (lens 31).

  If the lighting fixture of this embodiment is comprised as mentioned above, the display part 35 and the operation part (operation member 342) will be accommodated in the housing | casing 32, suppressing the enlargement of the housing | casing 32 of the emergency light source unit 3. FIG. can do.
