Embodiment 1 FIG.
FIG. 1 is a schematic configuration diagram showing a configuration of a lighting fixture according to Embodiment 1 of the present invention. The lighting apparatus 200 in the present embodiment includes a discharge lamp 1 that is a light emitting unit, a reflector 2 that reflects light emitted from the discharge lamp 1, and an inverter circuit 3 that is a drive unit that supplies power to the discharge lamp 1 to light it. The discharge lamp 1 is turned on, turned off, and the control signal 4 for controlling the inverter circuit 3 is generated so as to be dimmed and output to the inverter circuit 3. The inverter control circuit 5 and the discharge lamp 1 are controlled by the remote controller. The wireless antenna 7 is configured to receive a wireless signal 7 transmitted from the controller 6 and output the received signal 8 to the inverter control circuit 5. Here, the inverter control circuit 5 includes a demodulation unit (not shown) that demodulates the reception signal 8 output from the wireless antenna 7, and control information for controlling the inverter circuit 3 included in the reception signal 8 by the demodulation unit. And a control signal 4 is generated based on this control information. The controller 6 is portable. Moreover, the lighting fixture 200 is attached to the ceiling 210 etc. with the fixture which is not shown in figure. The luminaire 200 may be embedded in the ceiling 210 so that the surface formed by the opening 20 through which light from the discharge lamp 1 passes and radiates to the space coincides with the lower surface of the ceiling 210.

  FIG. 2 is an external view of the lighting apparatus according to Embodiment 1 of the present invention. The discharge lamp 1 is a straight fluorescent lamp and is attached to a lamp socket 10. The discharge lamp 1 is lit by power supplied from an inverter circuit 3 (not shown) via a lamp socket 10. The reflecting plate 2 has a substantially U-shaped cross section, and is disposed symmetrically with the reflecting plate 2 a with respect to the reflecting plate 2 a provided with the radio antenna 9, the reflecting plate 2 b disposed on the back surface of the discharge lamp 1, and the discharge lamp 1. It is comprised from the reflecting plate 2c. The radio antenna 9 is a microstrip antenna, and a metal pattern of this antenna is formed in a planar shape on the surface of the dielectric substrate. The radio antenna 9 is provided on the reflection plate 2a so as to form a part of the reflection surface of the reflection plate 2a with respect to the light from the discharge lamp 1. Here, the radio antenna 9 is provided on the reflecting plate 2a so that the surface on which the metal pattern is provided coincides with the surface of the reflecting plate 2a.

Next, the operation will be described.
The inverter circuit 3 is supplied with an AC voltage from a commercial AC power source, converts the AC voltage into a rectified and smoothed DC voltage, and switches the DC voltage with a switching element to convert it into a high-frequency AC voltage. The inverter circuit 3 supplies this high frequency voltage to the discharge lamp 1. The inverter circuit 3 receives the control signal 4 from the inverter control circuit 5 and controls the high-frequency power supplied to the discharge lamp 1 based on the control signal 4. Here, the control signal 4 is a signal for performing control such as dimming for starting or turning off the discharge lamp 1 or changing the light output of the discharge lamp 1, and turning on the AC power to the inverter circuit 3 The high frequency power is controlled by turning off, controlling the DC voltage value, or controlling the switching frequency.

  The controller 6 transmits a wireless signal 7 for controlling the discharge lamp 1 to the wireless antenna 9. The wireless antenna 9 that has received the wireless signal 7 outputs the received signal 8 to the inverter control circuit 5. The inverter control circuit 5 generates a control signal 4 based on the reception signal 8 input from the wireless antenna 9 and outputs the control signal 4 to the inverter circuit 3. Thus, the discharge lamp 1 is controlled by the radio signal 7 transmitted from the controller 6.

  3 and 4 are layout diagrams showing the installation position of the wireless antenna 9. FIG. 3 shows the case where the cross section of the reflector 2 is substantially U-shaped, and FIG. 4 shows the case where the cross section of the reflector 2 is W-shaped, as in FIGS. 1 and 2.

  The installation position of the wireless antenna 9 shown in FIGS. 1 and 2 corresponds to the case where the wireless antenna 9a is installed on the reflection plate 2a of FIG. The radiation pattern 91a of the wireless antenna 9a with respect to the wireless signal 7 depends on the configuration of the microstrip antenna constituting the wireless antenna 9a, but generally has a peak in a direction 92a orthogonal to the surface on which the metal pattern of the microstrip antenna is provided. Have. Therefore, when the luminaire 200 is attached to the ceiling 210, the reception sensitivity in the direction directly below the radio antenna 9a, that is, in the direction passing through the radio antenna 9a and orthogonal to the ceiling 210 is lower than the peak direction 92a. There is almost no sensitivity in the direction orthogonal to 92a. If the controller 6 is arranged in such a direction, the radio signal 7 is not efficiently received by the radio antenna 9a, and the discharge lamp 1 cannot be controlled. Therefore, by newly installing the wireless antenna 9c on the reflection plate 2c, it is possible to efficiently receive the wireless signal 7 coming from the direction where the reception sensitivity of the wireless antenna 9a is poor. Instead of installing the radio antenna 9a or 9c on the reflecting plate 2a or 2c, the radio antenna 9b may be provided on the reflecting plate 2b. The radio antenna 9b can receive the radio signal 7 efficiently because the direction directly below coincides with the peak direction 92b.

  FIG. 4 shows a case where the reflecting plate 2 has a W-shaped cross section and includes two discharge lamps 11 and 12. When the wireless antenna 9e is installed on the reflecting plate 2e, the reception sensitivity is low in the direction directly below the antenna 9e and the boresight direction 92e of the antenna 9e is similar to the case where the wireless antenna 9c is provided on the reflecting plate 2c in FIG. There is almost no reception sensitivity in the orthogonal direction. Therefore, a new wireless antenna 9f is provided on the reflecting plate 2f, so that the wireless signal 7 coming from the direction of poor reception sensitivity of the wireless antenna 9e can be received efficiently.

  3 and 4 show the cases where the respective radiation patterns 91a, 91c, 91e, and 91f of the wireless antennas 9a, 9c, 9e, and 9f have peaks in their respective peak directions. The microstrip antenna pattern to be formed may be arrayed, and the phase of feeding each of the arrayed antenna patterns may be adjusted so that the phase of each antenna pattern is aligned in the direction directly below the antenna. It can be configured such that the radiation pattern has a peak directly below the antenna.

  Thus, since the radio antenna 9 is provided on the reflecting plate 2 so as to be a part of the reflecting surface of the reflecting plate 2, it does not block the light emitted from the discharge lamp 1 and can prevent a reduction in illumination efficiency. Further, the wireless antenna 9 is not conspicuous and does not impair the beauty.

The wireless antenna 9 is provided on the reflector 2 so as to form a part of the reflector 2. In FIG. 5B, the reflecting surface 22 of the reflecting plate 2 and the surface 94 on which the metal pattern of the wireless antenna 9 is provided are curved surfaces. For example, the normal direction of each curved surface is continuously connected, and the surface 94 The radio antenna 9 is provided on the reflection plate 2 so as to form a part of the reflection surface 22. 5A and 5B, there may be a step between the reflecting surface of the reflecting plate and the surface on which the metal pattern of the wireless antenna is provided.
