[0002]

2. Description of the Related Art FIG. 6 is a view showing a mode of use of a remote control type luminaire, in which 1 is a luminaire and 2 is a remote control transmitter for transmitting an infrared signal. The lighting fixture 1 has a diffusion / transmissive cover 4 removably attached to the lower surface of a chassis 3 directly attached to the ceiling, and various electric devices that are covered with the cover 4 as shown in FIG. Two large and small ring-shaped fluorescent lamps 5 and 6, ballasts 7 and 8 for each lamp, starters 9 and 10 for each lamp, a night light socket 12 to which a night light 11 is attached, a remote control receiving unit 13, and an auxiliary switch. 14 and the like are attached to the chassis 3, respectively. Reference numeral 15 is a cover mounting tool, and 16 is a lamp holder.

The receiving unit 13 has a light receiving portion 17 for receiving a signal transmitted from the transmitter 2, a microcomputer 18, and a reset switch 19. The microcomputer 18 determines the contents received by the light receiving unit 17, and controls the lamps 5 and 6 and the night light 11 according to the contents received (lighting, dimming, extinguishing, etc.). The computer 18 has an all-light mode in which all the lamps 5 and 6 are turned on when the power is turned on.

Further, the microcomputer 18 superimposes abnormal noise on the circuit due to discharge caused by lightning strike,
For the sake of safety in the event of an abnormality due to the superposition of signal noises transmitted from other electrical products on the circuit, etc., it has a protective function that temporarily suspends the function of this computer 18 immediately before the abnormality. In addition, it has a reset function for canceling the protection state (temporary stop state) by this protection function.

The reset switch 19 is provided to operate the reset function for executing the reset program of the microcomputer 18 to return the state of the microcomputer 18 to the initial state.

The auxiliary switch 14 is provided to cope with the loss of the remote control transmitter 2 and the situation in which the transmitter 2 cannot be used because the battery has run out.

The respective electric devices are electrically connected to each other as shown in FIG. 8. In FIG. 8, 20 is a commercial AC power source and 21 is a hook ceiling. As shown in FIG. 8, the remote control receiving unit 1
Reference numeral 3 is directly connected to a power source through a power line 22, and the auxiliary switch 14 is connected to the unit 13 through a signal line 23 so that the ON / OFF signal of the auxiliary switch 14 is input to the unit 13.

[0008]

In the luminaire having the above-mentioned structure, the microcomputer 18 used for the luminaire has a resetch function, and the reset switch 19 is required accordingly. Therefore, the cost of the receiving unit 13 is reduced. Is high. Therefore, there is a problem that it is disadvantageous when the cost of the entire device is reduced.

In addition, a reset switch 19 for canceling the protection operation (temporary suspension of the function) of the microcomputer 18 and an auxiliary switch 14 for coping with the loss or the function stop of the remote control transmitter 2 are provided. Therefore, there is a possibility that confusion may occur in the operation of these two types of switches 14 and 19.

Further, if a power failure occurs after the user goes out in the off state and the power failure is resolved, the microcomputer 18 is turned on at the same time as the power failure is resolved. Therefore, the fluorescent lamps 5 and 6 are turned on by the all-light mode in which all the lamps 5 and 6 are turned on, and there is a problem that this unnecessary lighting continues until the user returns home.

The object of the present invention is inexpensive and does not cause confusion in the function recovery operation of the microcomputer provided in the remote control receiving unit.
Moreover, the purpose is to obtain a lighting fixture that does not have unnecessary lighting due to a power failure and its solution.

[0012]

According to the present invention, there is provided a remote control receiving unit for receiving a signal transmitted by a remote control transmitter, and this unit controls a lamp according to the contents of the reception. Further, the invention is applied to a lighting fixture including a microcomputer having a lighting mode for lighting the lamp when the power is turned on. In order to achieve the above object, a normally-closed manually-operated open / close switch is provided in the middle of a power supply wire for supplying power to the receiving unit.

[0013]

In the lighting equipment, when the open / close switch is manually turned off, the power supply to the receiving unit is cut off. Therefore, even if there is a power failure in this cutoff state, the power is supplied to the receiving unit as the power failure disappears. Therefore, since the microcomputer included in this unit is not reset to the initial state, the unnecessary lighting state by the lighting mode is not formed.

When an abnormality occurs and the microcomputer temporarily suspends its function, the open / close switch is once turned off and then turned on.
You can power cycle the microcomputer to reset the protected state of the computer and restore functionality. Therefore, it is not necessary for the microcomputer to have a reset function.

When the transmitter for remote control cannot be transmitted due to loss or the like, the open / close switch is once turned off and then turned on again to turn on the microcomputer again. The lamp can be turned on in the lighting mode.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a perspective view showing an overall structure of a lighting fixture 31 according to an embodiment of the present invention together with a transmitter 50. As shown in this drawing, the lighting fixture 31 is directly attached to a ceiling, for example, a circular shape. A cover 33 made of a diffusion permeable synthetic resin material or the like is detachably provided on the lower surface of the chassis 32. Incidentally, reference numeral 34 in FIG. 3 denotes a cover attachment, which is attached to the lower surface of the chassis 32.

As shown in FIGS. 2 and 3, on the lower surface of the chassis 32, various electric devices, that is, two large and small ring-shaped fluorescent lamps 35 and 36, and respective lamps 35 and 36 are provided.
C & C (coil and core) type ballasts 37,3
8, electronic starters 39, 40 for each lamp 35, 36,
A night light socket 42 to which the night light 41 is attached, a remote control receiving unit 43, and an opening / closing switch 44 are attached.

Is detachably supported by the first mounting portion. The small-diameter fluorescent lamp 36 is for 30 W, is detachably supported by the second mounting portions of the plurality of lamp holders 45, and is concentrically arranged inside the fluorescent lamp 35.

The open / close switch 44 is a normally-closed switch whose contacts are always kept closed, and the contacts are manually opened and closed. In this embodiment, a normally closed pull switch is adopted as the switch 44 so that the switch 44 can be easily operated from the outside of the luminaire 31 without removing the cover 33 one by one. As shown in FIG. 1, it is hung outside the lighting fixture 31. In addition, reference numeral 46 in FIG. 1 denotes a guide for the scanning cord 44 a fixed to the chassis 32.

FIG. 5 is a connection diagram showing the electrical connection relationship of the various electric devices, in which 47 is a commercial AC power source, and 48 is a commercial AC power source.
Is a hook ceiling provided on the ceiling. The power supply electric wire 49 connected to the hook ceiling 48 is connected to the receiving unit 43, and an opening / closing switch 44 is inserted in the middle thereof.

The receiving unit 43 includes a light receiving section 51 for receiving a signal (infrared ray) transmitted from the remote control transmitter 50 shown in FIGS. 1 and 4, and the received contents of the light receiving section 51 are A microcomputer 52 is provided for controlling (lighting, dimming, extinguishing, etc.) the fluorescent lamps 35, 36 and the night light 41 according to the contents of the reception.

It should be noted that the transmitter 50 includes a push operation section 50a as shown in FIG.
One lighting display, that is, all fluorescent lamps 35, 3
6 is turned on, an all-lamp display section 50b is displayed, a reduced-light display section 50c is displayed that only the fluorescent lamp 35 is turned on, a night-light display section 50d that is displayed that only the night-light 41 is turned on, and an off-light. It has a turn-off display section 50e for displaying. Each time the pressing operation unit 50a is pressed, the respective display units 50b to 50e are switched in the order of this description so as to light up and display.

The microcomputer 52 uses all the fluorescent lamps 3 as a lighting mode, for example, when the power is turned on.
It has an all-light mode for turning on the lights 5 and 36. Further, the microcomputer 52, for example, superimposes abnormal noise on the circuit due to discharge caused by lightning, superimposes signal noise transmitted from other electric products on the circuit, or the like, for safety in case of abnormality, It has a protection function of temporarily and automatically stopping the function of the computer 52 to the state immediately before the abnormality. Moreover, the computer 52 does not have a reset function for canceling the protection state (temporary stop state) by the protection function, and therefore a low-cost microcomputer is adopted.

As shown in FIG. 5, the fluorescent lamp 3 is used.
A nightlight socket 42 is connected to the reception unit 43 through a nightlight electric wire 53 for controlling the night lights 5, 36 and the nightlight 41. Further, for similar control, the fluorescent lamp 35 is connected to the receiving unit 43 together with the ballast 37 and the electronic starter 39 for the fluorescent lamp 35 via the electric wire 54 as shown in FIG. The lamp 36 has a ballast 38 and an electronic starter 4 therefor.
0 is connected via the electric wire 55 as shown in FIG.

In the luminaire having the above structure, the power supply wire 4
Since the open / close switch 44 provided in the middle of 9 is normally used while maintaining the closed state, in normal use,
The receiving unit 43 is supplied with power and is in an operable state. Therefore, when the user operates the remote control transmitter 50 to transmit to the lighting fixture 31, and the signal is received by the light receiving unit 51 of the receiving unit 43, the received signal is received by the micro-device in the receiving unit 43. It is sent to the computer 52 and converted into an electric signal, and the received content is judged by the computer 52.

Therefore, according to the processing in the microcomputer 52 based on the received contents, the control according to the received contents, that is, the fluorescent lamps 35 and 36 and the night light 4 is performed.
Turning on, dimming, turning off, etc. of 1 are implemented. In this control, when operating from the time of turning off the light, first, the all-light mode of the microcomputer 52 is first executed to turn on the fluorescent lamps 35 and 36.

When power is supplied to the receiving unit 43, an abnormal voltage due to a lightning strike is superimposed on the circuit, or a signal generated by another electric product is superimposed on the circuit to cause an abnormal condition. The microcomputer 52 of the receiving unit 43 maintains the state immediately before the abnormal state occurs due to its protection function, and temporarily stops the function.

In such a case, in order to restore the function of the microcomputer 52, the operation cord 44a may be pulled twice so that the opening / closing switch 44 is once turned off and then turned on again. Then, after the power supply to the receiving unit 43 is cut off by the first pulling operation, the power is supplied again to the receiving unit 43 by the next pulling operation, so that the protection (temporary stop) state is reset. The function of the microcomputer 52 is restored.
Therefore, since the receiving unit 43 does not need the reset function and the reset switch that enables it, an inexpensive receiving unit 43 without them can be used.

When the transmitter 50 is lost or cannot be transmitted due to the battery life of the transmitter 50, in order to operate the lighting fixture 31, the open / close switch 44 is once pressed as in the case of the function recovery. The operation string 44a may be pulled twice to turn it on after turning it off. Then, since the power supply to the receiving unit 43 is cut off by the first pulling operation, the lighting fixture 31 in the lighting state can be turned off, and the power is supplied to the receiving unit 43 again by the next pulling operation, and accordingly the microcomputer. 52
Since the function of is restored, the lighting fixture 31 can be turned on by the all-light mode.

The one open / close switch 44 also serves as a switch for resetting the suspended state of the function by the protection function of the microcomputer 52 and a switch for handling when the transmitter 50 becomes unable to transmit as described above. Therefore, the switch operation is not mistaken in these situations.

Further, if the power supply to the receiving unit 43 is cut off by turning off the open / close switch 44, there is a power failure in that state. Therefore, power is not supplied to the receiving unit 43. In other words, the power off / on signal due to the power failure is not supplied to the receiving unit 43.

Therefore, the microcomputer 52 does not arbitrarily turn on the lighting device 31 in the all-light mode, and unnecessary lighting can be eliminated when going out.

The present invention is not limited to the above embodiment. For example, an incandescent lamp other than a fluorescent lamp can be used as the lamp, and the number of lamps used can be at least one. The present invention can also be applied to other lighting fixtures such as a hanging type, a ceiling-embedded type, and a bracket type.

[0034]

As described above in detail, according to the configuration of the lighting apparatus of the present invention, the switch for resetting the paused state by the protection function of the microcomputer included in the remote control receiving unit and the remote control transmitter are provided. Since one open / close switch can double as a switch to handle when transmission is no longer possible,
There is no confusion in the switch operation, and since it is not necessary for the microcomputer to have a reset function, the cost of the receiving unit equipped with this microcomputer can be reduced, and the equipment can be obtained at a low cost accordingly. . Moreover, by turning off the open / close switch and cutting off the power supply to the receiving unit,
Even if there is a power failure in this cutoff state and the failure is resolved, the microcomputer is not reset to the initial state, so that an unnecessary lighting state due to the lighting mode of the microcomputer is not formed due to the power failure and its elimination.
