DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting control device suitable as a remote control lighting fixture. In this specification,
When referring to CPU, ROM, RAM, and EEPROM,
Includes all functions that have substantially the same functions as these but can be called differently.

[0002]

2. Description of the Related Art Recently, EEPROMs that do not require a lithium battery or the like for backing up stored contents have come to be used. It is also proposed to be used for remote control lighting equipment and the like. In this case, in the normal operation immediately after the power is turned on, the contents stored in the EEPROM are
Upon reading to the AM, the light source is configured to operate according to this stored content.

[0003]

However, if the general user wants to stop the microcomputer runaway or mess with the lighting mode of the light source and return it to the standard mode at the time of factory shipment, these two types of problems are to be solved. No method has been proposed yet that makes it easy to reset all together. SUMMARY OF THE INVENTION It is an object of the present invention to provide a lighting control device and a remote-control lighting device provided with reset means that can be easily operated by a general user.

[0004]

SUMMARY OF THE INVENTION The present invention is directed to a CPU, RO having a hard reset port and a soft reset port.
M, RAM, EEPROM, and a light source controlled by a CPU are provided. In a normal operation immediately after power-on, the memory contents of the EEPROM are read out to the RAM and the light source operates according to the memory contents, and a reset switch Is configured by a single one, the hard reset port is activated by the operation of the reset switch, and the soft reset port is configured to remain active for a predetermined time even after the hard reset port is activated. Reads the memory contents of the ROM into the RAM, and configures a lighting control device configured so that the light source operates according to the memory contents. Further, in this configuration, a remote control-type lighting fixture including a lighting control device that inputs a signal from a receiving unit that receives a remote control signal to the CPU is configured.

[0005]

According to the present invention, the reset switch is composed of a single unit and is provided with reset means that can be easily operated by a general user. When the reset switch is operated, the hard reset port becomes active, and the soft reset port becomes hard. The reset port is configured to remain active for a predetermined period of time after it becomes active.
The memory contents of M are read into the RAM, and the light source operates according to this memory contents. Therefore, in the unlikely event that the microcomputer runaway is stopped or the light source lighting mode or the like is tampered with excessively and it is desired to return to the standard mode at the time of factory shipment, it is easy to collectively reset these two types of resets.

[0006]

An embodiment of the present invention will be described with reference to the drawings.

In this embodiment, a CPU 1 having a hard reset port HP and a soft reset port SP, a ROM
2, RAM3, EEPROM4, CPU1 control unit 9
And a light source 5 controlled via the. In a normal operation immediately after the power supply 6 is turned on, the stored contents of the EEPROM 4 are read out to the RAM 3, and the light source 5 operates according to the stored contents. The reset switch 7 is composed of a single element, the hard reset port HP is activated by the operation of the reset switch 7, and the soft reset port SP is kept active for a predetermined time even after the hard reset port HP is activated. As a result, the contents stored in the ROM 2 are read out to the RAM 3, and the light source 5 operates according to the contents stored. Also, the remote control signal R
A signal from the receiving unit 8 that receives C is input to the CPU 1.

More specifically, the EEPROM 4 includes:
At least when the power source 6 is turned off, the stored contents of the RAM 3 are read. Immediately after the power source 6 is turned on, the previous lighting mode can be reproduced immediately after the power source 6 is turned on. In the case of seeds, each dimming degree (contents of lighting scene) can be reproduced. In the normal operation immediately after the power supply 6 is turned on, as shown in FIG.
And the hard reset port HP via the reset IC 11
The rising signal is input to the hard reset port H
P becomes active, the DC power supply 10 output (VDD) rises to the soft reset port SP slightly slowly, and the resistance 12
However, after the hard reset port HP becomes active, it is inactive (H level), so that the storage contents of the EEPROM 4 are read out to the RAM 3 as shown in FIG.

Next, when it is desired to stop the runaway of the microcomputer or to mess up the lighting mode of the light source 5 with a remote control transmitter (not shown) or the like and restore the standard mode at the time of factory shipment, these two types are required. The reset switch 7 is composed of a single unit so that the resets can be collectively reset. When it is desired to reset, the push button type reset switch 7 may be turned on for a moment. Then, the hard reset port HP is connected via the transistor 13 as shown in FIG.
After it once goes low, it goes high at time t0, and a hard reset functions with this rising active signal. On the other hand, the soft reset port SP has the transistor 15 until the charge stored in the capacitor 14 is discharged.
, Is maintained at the L level until time t2, and thereafter rises to the H level. With this configuration, the soft reset port SP is kept active (L level) for a predetermined time (until time t2) even after the hard reset port HP becomes active (time t0), whereby, for example, t1 From the time, as shown in FIG. 2, the RAM 3 is initialized and the contents stored in the ROM 2 (standard mode at the time of factory shipment)
Is read into the RAM 3, and the light source 5 operates according to the stored contents.

According to the present embodiment, the reset switch 7 is composed of a single unit and is provided with a reset means that can be easily operated by a general user. The operation of the reset switch 7 activates the hard reset port HP, and the soft reset port HP is activated. The reset port SP is configured to remain active for a predetermined time even after the hard reset port HP becomes active, whereby the storage content of the ROM 2 is read to the RAM 3 and the light source 5 operates according to this storage content. . Therefore, in the unlikely event that the microcomputer runaway is stopped or the lighting mode of the light source 5 is tampered with excessively and it is desired to return to the standard mode at the time of factory shipment, it is easy to collectively reset these two types of resets.

[0011]

As described above, according to the present invention, the reset switch is composed of a single unit and is provided with reset means that is easy for a general user to operate. When the lighting mode or the like is tampered with too much and the user wants to return to the standard mode at the time of factory shipment, it is easy to reset these two types of resets together.
