(Embodiment)
FIG. 1 is a perspective view showing an example of a lighting fixture according to an embodiment of the present invention. The luminaire 100 is a direct-mounted luminaire and is used by being attached to a ceiling or a wall.

  The luminaire 100 includes a main body 11, a fluorescent lamp 12, a fluorescent lamp lighting circuit 13, a remote control receiver 14, a shade cover 15, a lamp holder (supporting member) 16, a lamp socket 17, and an integrated nightlight unit 30. The fluorescent lamp 12 includes two large and small circular fluorescent lamps. The integrated nightlight unit 30 is attached to the main body 11 using screws or the like.

  FIG. 2 is a schematic configuration diagram showing an example of an integrated nightlight unit used in the lighting apparatus according to the embodiment of the present invention. 2A is a plan view seen from the illumination side, and FIG. 2B is a cross-sectional view taken along line MM in FIG. 2A.

  The integrated nightlight unit 30 includes an LED element 31, a light cover 32, an LED lighting circuit 33, a housing 34, and wiring 36.

  The integrated nightlight unit 30 incorporates the LED element 31 into a housing 34 having a built-in LED lighting circuit 33 therein. The integrated nightlight unit 30 is formed integrally with the housing 34 in substantially the same shape so that the incandescent lamp, which is a related technology, can be used for a lighting fixture.

  The external power supply and the LED lighting circuit 33 can be electrically connected by the wiring 36 of the integrated nightlight unit 30. At this time, since the LED lighting circuit 33 performs conversion from an AC power source to a DC power source so that an external power source can be used by the LED element 31, the integrated nightlight unit 30 is supplied with power from the outside. The LED element 31 can be turned on.

  The light cover 32 protects the LED element 31 and adjusts the irradiation range and color of the LED element 31, and is formed of a material that transmits light, such as acrylic. By using a material that diffuses the light of the LED element 31 for the light cover 32 or a shape that diffuses the light, the light of the LED element 31 having the characteristics of a point light source can be made more surface light source. It is possible to make light irradiation close to.

  By using an integrated nightlight unit that uses LEDs, it is possible to achieve long life and energy saving of the nightlight. In addition, since the LED lighting circuit and the light part can be integrated as one member, the number of components can be reduced and the manufacturing process can be simplified.

  The fluorescent lamp 12 is fixedly supported on the main body 11 by the lamp holder 16, and at the same time, the pin of the lamp socket 17 of the fluorescent lamp 12 is connected to the pin receiver of the main body 11. At this time, the main body 11 and the fluorescent lamp 12 are in an electrically connected state.

  The lighting apparatus 100 is attached to a ceiling surface or a wall surface with a connector that also serves as a hook. A spacer is interposed between the main body 11 and the ceiling surface in order to stabilize the lighting apparatus 100. The luminaire 100 is connected to a power line via a connector, and for example, 100V AC power is supplied. The fluorescent lamp lighting circuit 13 is connected to the power line and lights the fluorescent lamp 12. Further, the LED lighting circuit 33 of the integrated nightlight unit 30 is also connected to the power line, and the LED element 31 is turned on. However, the power supplied to the LED element 31 is converted into pulsating power that can be applied to the series circuit by rectifying AC power through a rectifier or the like before being supplied to the LED element 31.

  The fluorescent lamp lighting circuit 13 and the LED lighting circuit 33 are electrically connected. In the luminaire 100, the fluorescent lamp lighting circuit 13 operates independently of the fluorescent lamp 12, and the LED lighting circuit 33 operates independently of the LED element 31. The lighting control is performed by switching the connection between the external circuit, the fluorescent lamp lighting circuit 13 and the LED lighting circuit 33, and the lighting control device (not shown) such as a remote controller via the remote control receiver 14. Specifically, a signal is transmitted to the remote control receiver 14 of the lighting fixture 100, and only the fluorescent lamp lighting circuit 13 or the fluorescent lamp lighting circuit 13 and the LED lighting circuit 33 are built in. The light source is turned on and off by controlling the logic circuit or its semiconductor integrated circuit.

  The lighting control performed by the lighting control device such as a remote controller is, for example, lighting of the two fluorescent lamps 12, dimming by either the large fluorescent lamp 12 or the small fluorescent lamp 12, and the LED element 31 in that order. . Alternatively, the two fluorescent lamps 12 are turned on in the order of light extinction by continuous light control or multistage light control and then the LED element 31. By controlling the LED element 31 not to be lit when the fluorescent lamp 12 is lit, the life of the LED element 31 is prevented from being shortened. Further, since it is not necessary to turn on the fluorescent lamp 12 when the LED element 31 is turned on, control is performed so that the fluorescent lamp 12 is not turned on at the same time.

  FIG. 3 is a perspective view showing an example of a lighting fixture according to a modification of the embodiment of the present invention. The luminaire 100 is a direct-mounted luminaire and is used by being attached to a ceiling or a wall. The basic structure is the same as that of the lighting apparatus according to the embodiment shown in FIG. 1, and includes a pull string 18 and a switch spring 19 instead of the remote control receiver 14.

  FIG. 4 is a schematic configuration diagram illustrating an example of an integrated nightlight unit used in a lighting apparatus according to a modification of the embodiment of the present invention. It is shown in a cross-sectional view as in FIG.

  The basic structure is the same as the integrated nightlight unit according to the embodiment shown in FIG. 2, and the integrated nightlight unit 30 further includes a switch 35 with a drawstring. The corded switch 35 has a lighting control function, and can switch the connection of the LED lighting circuit 33, an external circuit, and a power source.

  The switch 35 with the drawstring is covered with a shade cover 15 that is fitted to the main body 11 of the lighting apparatus 100, and therefore the switch spring 19 is used. The switch spring 19 changes the movable direction of the drawstring-attached switch 35 so that lighting control can be performed from the outside of the shade cover 15. By pulling the pull string 18 connected to the pull string switch 35 via the switch spring 19, lighting control of the lighting apparatus 100 can be performed. The drawstring 18 is not limited to a string, and may be a metal ball chain, a plastic thin rod, or the like, and may be provided with a knob at the end portion.

  The LED lighting circuit 33 that can be controlled by the switch 35 with the drawstring of the integrated nightlight unit 30 and the fluorescent lamp lighting circuit 13 are electrically connected so that the lighting control can be performed in a lump. By operating the drawstring 18 via 19, it is possible to control the lighting of both the fluorescent lamp 12 of the luminaire 100 and the LED element 31 of the integrated nightlight unit 30.

  The lighting control performed by the corded switch 35 is, for example, lighting the two fluorescent lamps 12, dimming by either the large fluorescent lamp 12 or the small fluorescent lamp 12, and the LED element 31 in this order. By controlling the LED element 31 not to be lit when the fluorescent lamp 12 is lit, the life of the LED element 31 is prevented from being shortened. Further, since it is not necessary to turn on the fluorescent lamp 12 when the LED element 31 is turned on, control is performed so that the fluorescent lamp 12 is not turned on at the same time.

  The lighting fixture 100 shown in the modification of the embodiment has been described as performing the lighting switching operation with the drawstring 18. A lighting control device such as a remote control receiving unit 14 and a remote controller may be provided, and lighting switching may be performed using the drawstring 18 and the remote controller together. Further, the remote control may have a lighting control function separately for lighting the fluorescent lamp 12 of the lighting apparatus 100 and the drawstring 18 for lighting the LED element 31.

  As explained above, according to the lighting fixture concerning this Embodiment, it can light for a long time with power saving.

  Replacing the nightlight incandescent lamp with the LED enables long life and energy saving, so that the electricity cost can be reduced, and the light source replacement becomes unnecessary or the frequency of light source replacement is reduced. In addition, there is a feature of mercury-free, and it is possible to reduce the burden on the environment.

  In addition, it is possible to use a lighting apparatus of related technology as it is at the time of replacement, which not only increases versatility but also is highly convenient.

  Furthermore, by using an integrated nightlight unit using LED elements, it can be handled as one member, so that the number of parts can be reduced and the manufacturing process can be simplified.

  In addition, it is possible to switch the lighting of the fluorescent lamp and the night light of the LED element by a remote control device such as a switch or a remote controller. When the fluorescent lamp is lit, the night light is not turned on, and when the night light is turned on, the fluorescent lamp is not turned on. It can be used with a long life and energy saving.

  The lighting fixture according to the present embodiment may be directly attached to the wall in addition to being directly attached to the ceiling, and its shape and type can be arbitrarily applied.

  Further, the shape of the fluorescent lamp, the lighting control method and the lighting order, and the dimming method such as dimming and extinction are examples. These can be arbitrarily changed and modified, and the present invention can be applied to various lighting fixtures.

  In addition, the shape and size of the integrated nightlight unit, and the number and arrangement of the LED elements to be used are not limited to the examples described above. Any shape can be set as long as it is a shape that can be used with a nightlight of a related art lighting fixture.
