Abstract

PURPOSE:To prevent an erasure of the data for lighting control even though there is a power source shielding such as a wall switch by providing a remote control transmitter, a remote control receiver, a nonvolatile memory, and a decision/control member to control the lighting load. CONSTITUTION:A lighting control instruction delivered from a remote control transmitter 1 is received by a remote control receiver 3, and fed to a decision/ control member 5. The decision/control member 5 controls a turning on and off, a dimming, and the like of a lighting load 9, depending on the light control instruction, and at the same time, stores the data for light control included in the light control instruction in a nonvolatile memory 7. In this case, when a power source 13 of the lighting apparatus is turned on again after turning off by a wall switch 11 or the like, the light control data is read from the nonvolatile memory 7, and the lighting load 9 is controlled depending on the data. Consequently, a loss of the lighting condition set formerly owing to a turning-off of the power source by the wall switch 11, a power failure, or the like, can be prevented.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a remote control type lighting fixture, and particularly to a lighting fixture using a so-called wireless remote control. The present invention relates to a lighting fixture that prevents lighting control information set by control from being erased.

(Prior Art) Conventionally, lighting equipment has been known that has a pull switch or a mechanical contact and can change and set lighting conditions such as brightness. In addition, recently, lighting fixtures whose lighting conditions can be controlled using a wireless remote control have been on sale. In lighting equipment that has such a wireless remote control, dimming level settings, lighting, turning off, and other operations can be performed remotely by sending control signals from a remote control transmitter to a remote control receiver installed in the lighting equipment. It was possible.

(Problem to be Solved by the Invention) Among these conventional lighting fixtures, in those that switch the lighting state using mechanical contacts such as pull switches, after the lighting fixture is turned off by operating a wall switch, Even when the lights were turned on again, it was possible to reproduce the lighting conditions set by a pull switch before turning them off. However, for lighting equipment whose lighting status is controlled by a wireless remote control, once the power is turned off using a wall switch, etc., the information for lighting control stored in the random access memory inside the lighting equipment is erased, and the lighting control information is erased again. When the power is turned on, the lighting state is initialized and becomes a full-light state, which is an inconvenience.

SUMMARY OF THE INVENTION An object of the present invention is to provide a lighting fixture in which information for lighting control is not erased even when the power is cut off by a wall switch or the like, in view of the problems with the conventional lighting fixtures described above.

(Means for Solving the Problems) In order to achieve the above-mentioned object, a remote control type lighting device according to the present invention includes a remote control transmitter for transmitting lighting control commands, and a remote control transmitter for receiving commands from the remote control transmitter. a lighting load; a non-volatile storage section for storing control information for the lighting load; and a judgment control section that performs control.

(Function) In the lighting fixture described above, the lighting control command sent from the remote control transmitting section is received by the remote control receiving section and supplied to the judgment control section. The judgment control section performs blinking, dimming, and other controls of the lighting load based on this lighting control command, and stores information for lighting control included in this lighting control command in the nonvolatile storage section. In this way, the lighting load is controlled by the lighting control command from the remote control transmitter, but if the power to the lighting equipment is turned off and then turned on again by a wall switch or the like, the non-volatile memory Lighting control information is read out from the controller, and the lighting load is controlled based on this information. This prevents loss of the previously set lighting state due to power cut-off by a wall switch or the like and power outage.

(Example) Hereinafter, the present invention will be explained in detail with reference to the drawings.

FIG. 1 shows a schematic configuration of a lighting fixture according to an embodiment of the present invention. The lighting equipment shown in the figure includes a remote control transmitting section 1, a remote control receiving section 3 that receives infrared signals, radio signals, and other signals from the remote control transmitting section 1, and a judgment control section 5 composed of a microcomputer or the like. Electrically programmable and erasable memory device (EEPROM)
), a lighting load having an illumination lamp such as a fluorescent lamp, a wall switch 11, a power supply section 13, and the like.

The remote control transmitter 1 in the lighting fixture shown in FIG. 1 includes, for example, a lighting (ON) switch 15 as shown in FIG.
, a light-off switch 17, one up switch and two down switches for adjusting the dimming level.
1. Note that the circuit such as the remote control receiving section 3 is provided within the lighting fixture body 23, for example, and is configured to be able to receive infrared signals, radio wave signals, etc. from the remote control transmitting section 1.

The operation of the lighting fixture having the above configuration will be explained with reference to FIG. 3. When the switch 11 in FIG. 1 is turned on, the judgment control unit 5 detects that the switch is on and reads information for lighting control, that is, lighting data, from the storage unit 7 into its own work area. This lighting data includes information regarding the lighting state stored in the storage unit 7 before the wall switch 11 is shut off. For example, the information includes information indicating the lighting state of the appliance, ie, lighting, extinguishing, dimming, etc., and information indicating the dimming level in the case of a dimming state. The judgment control unit 5 then controls the operation of the lighting load 9 based on such lighting data. For example, if the lighting data indicates 60% dimming, the lighting load 9 is turned on at a dimming level of 60%. In such a state, when a lighting control command signal is sent from the remote control transmitting section 1, the remote control receiving section 3
receives this and inputs it into the judgment storage section 5. Judgment storage unit 5
sets the lighting state of the lighting load 9 based on the lighting data included in this lighting control command, and also rewrites the lighting data stored in the storage unit 7 into data corresponding to this lighting control command. Thereafter, the judgment storage section 5 maintains the lighting state based on the lighting data sent from the remote control transmitter and stored in the storage section 7 until the wall switch is turned off, and the process ends when the wall switch is turned off.

In addition, although the above-mentioned embodiment explained the case where the present invention was applied to, for example, a home light with an infrared remote control, the present invention can be applied to various lighting equipment, such as office lighting fixtures, theater lighting equipment, and others. Yes, and it is clear that various remote control methods such as those using infrared rays, those using radio waves, and others can be applied.

(Effects of the Invention) As described above, according to the present invention, since the lighting control information is not lost due to power interruption of the lighting equipment by a wall switch or the like or power outage, even after the power is turned on, the illumination control information The state is reproduced.

Therefore, it is possible to reproduce the lighting condition without providing a mechanical contact such as a pull switch, and a lighting fixture that is preferable in terms of design is realized. Additionally, once you set the lighting conditions such as the dimming level using the remote control transmitter, you can then always blink at the desired dimming level using just a wall switch without using the remote control transmitter. become.
