  That is, it has a configuration including a long light guide having an entrance surface and an exit surface, and a light source unit having a light emitting element that allows light to enter from the entrance surface of the light guide. The light emitting element is configured to emit light via a power cord (for example, Patent Document 1 listed below exists as a prior document similar to this).

JP 2005-228536 A

  In the above conventional example, since power is supplied from the household power source to the light emitting element, wiring work for the power cord is required, resulting in poor workability in the field.

  Thus, it is conceivable to supply power from the battery to the light emitting element. However, when such a battery is used, a battery box for storing the battery is required, which increases the mounting width of the lighting device.

  That is, such a lighting device is installed in, for example, a staircase, a corridor, or a room. However, when the mounting width is widened, it protrudes toward the staircase, the corridor, or the indoor side. It becomes a so-called disturbing thing.

  Accordingly, the present invention aims to reduce the thickness.

  In order to achieve this object, the present invention includes a light guide having a long shape and having an entrance surface and an exit surface, and a light source unit having a light emitting element that allows light to enter from the entrance surface of the light guide. The light source unit includes a battery box disposed on an upper surface or a lower surface in a longitudinal direction of the light guide, and a light emitting element holding body that is integrated with the battery box and holds the light emitting element, and that emits light. The element holding body is provided with a lead wire for connecting the light emitting element and the battery box, thereby achieving the intended purpose.

  As described above, the present invention includes an elongated light guide having an entrance surface and an exit surface, and a light source unit having a light emitting element that allows light to enter from the entrance surface of the light guide. A battery box disposed on the upper or lower surface in the longitudinal direction of the light guide, and a light emitting element holder integrated with the battery box and holding the light emitting element, the light emitting element holder Since the lead wire for connecting the light emitting element and the battery box is provided, the thickness can be reduced.

That is, in the present invention, since the battery box constituting the light source unit is arranged on the upper or lower surface in the longitudinal direction of the light guide, a part of the thickness of the battery box is absorbed by the light guide. As a result, the overall thickness can be reduced.

  Therefore, when this lighting device is installed in, for example, a staircase, a corridor, or a room, the amount protruding toward the staircase, the corridor, or the room is reduced, and as a result, it becomes comfortable in real life. .
