Abstract

PURPOSE:To provide a reset means which can be easily operated by a general user. CONSTITUTION:A device is provided with a CPU 1 having a hard reset port HP and a soft reset port SP, a ROM 2, a RAM 3, an EEPROM 4, and a light source 5 controlled by the CPU 1 through a control part 9. In normal action immediately after a power supply 6 is on, memorized contents in the ROM 4 are read to the RAM 3, and the light source 5 is actuated in accordance with the memorized contents. A reset switch 7 is a single one, and the hard reset port HP becomes active by operation of it, while a soft reset port SP keeps being active for a specified period after the hard reset port HP becomes active, so by reading the memorized contents in the ROM 2 to the RAM 3, the light source 5 is actuated based on the memorized contents. A signal from a signal receiving part 8 to receive a remote control signal RC is inputted to the CPU 1.

Description

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, an EEPROM has been generally used which does not require a lithium battery for backing up stored contents. 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 that include a reset means that is easy for general users to operate.

[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. In addition, in this configuration, a remote control luminaire including a lighting control device in which a signal from a receiving unit that receives a remote control signal is input 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 too much and it is desired to restore the standard mode at the time of factory shipment, it is easy to collectively reset these two types of resets.

[0006]

Embodiments 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 the normal operation immediately after the power supply 6 is turned on, the contents stored in the EEPROM 4 are read out to the RAM 3 and the light source 5 operates according to the contents stored. 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:
The stored contents of the RAM 3 are read at least when the power source 6 is turned off, and the previous lighting mode can be reproduced immediately after the power source 6 is turned on next. 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 contents stored in the EEPROM 4 are read out to the RAM 3 as shown in FIG.

Next, in the event that the microcomputer runaway is to be stopped or the lighting mode of the light source 5 is messed up with a remote control transmitter (not shown) or the like and it is desired to return to 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.
As described above, after once becoming the L level, it becomes the H level at time t0, and the hard reset functions by 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.
The L level is maintained until time t2 via the, and then rises to the H level. With this configuration, the soft reset port SP is kept active (L level) for a predetermined time (until the time t2) even after the hard reset port HP is activated (at the time t0). 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)
To 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 reset.

[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.
