BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device whose lighting state can be changed using a control switch such as a remote control.

0003

2. Description of the Related Art Conventional lighting devices include incandescent lamps such as night lights and discharge lamps such as fluorescent lamps, and the discharge lamps and incandescent lamps are controlled by a control switch such as a remote control. In addition to the control switch, there is also a main switch such as a wall switch, which also turns on and off the discharge lamp and incandescent lamp. Then, when the main switch is turned on again after the main switch is turned off, the incandescent lamp and the discharge lamp are controlled in the state immediately before the main switch was turned off.

0004

[Problem to be solved by the invention] However, when all the light sources are turned off using the control switch,
When the main switch is turned off, neither the discharge lamp nor the incandescent lamp turns on even when the main switch is turned on again, leaving a pitch-dark state, which is inconvenient as the control switch must be operated in this state. For example, when returning home or entering a room, a wall switch, which is generally the main switch installed at the entrance, is operated, but even if only the wall switch is operated at this time, there is an inconvenience that it is completely dark.

Furthermore, for example, when switching from an incandescent lamp to a discharge lamp, especially when the discharge lamp is cold, there is an inconvenient state of total darkness after the incandescent lamp is turned off until the discharge lamp is turned on. It has a certain problem.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a lighting device that can avoid a completely dark state after operating a main switch or a control switch.

[Configuration of the invention]

[0008]

[Means for solving the problem] The thing according to claim 1 is:
By turning the lighting section on and off with the main switch, and operating the control switch when the main switch is on, the control section controls the up and down state of the lighting section, and turns it on again after the main switch is turned off. In a lighting device in which the lighting section is controlled in a lighting state immediately before the main switch is turned off, when the lighting section is in a predetermined state immediately before the main switch is turned off, the control section controls the main switch. When the main switch is turned on again after being turned off, the lighting section is controlled in another predetermined state.

[0009] According to a second aspect of the present invention, in the lighting device, the illumination device has an incandescent lamp and a discharge lamp, and a control unit controls the lighting states of the incandescent lamp and the discharge lamp by operating a control switch. When switching from a lighting state of the incandescent lamp to lighting of the discharge lamp, the control unit detects lighting of the discharge lamp with a lighting detection unit, and turns off the incandescent lamp after lighting the discharge lamp.

0010

[Operation] In the device according to claim 1, under normal conditions, the lighting section is turned off by turning off the main switch. When the main switch is turned on again, the control section sets the illumination section to the lighting state immediately before the main switch is turned off. Further, if the lighting section is in a predetermined state when the main switch is turned off, the control section sets the lighting section to another predetermined state when the main switch is turned on again.

[0011] According to the second aspect of the present invention, when switching to a discharge lamp when an incandescent lamp is turned on, the incandescent lamp is turned on after the lighting detection section detects that the discharge lamp is turned on, thereby eliminating a completely dark state.
