Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device having a delayed light-off function that turns off the light after a predetermined period of time by a light-off operation, and relates to a lighting device having a night light that can select a delayed light-off state.

[0002]

2. Description of the Related Art A conventional method for delaying lighting of a luminaire having a delayed lighting function equipped with a night light includes a method of turning off the night light after a predetermined time has passed after performing a turning-off operation when the night light is lit, a full lighting, and a gradation. There were some lights that were turned off in a delayed order, such as lighting and then night lights. The setting of the operation time of the delayed lighting is controlled by the charging time of the condenser of the delay control timer inside the lighting equipment. Also,
In some cases, the delay operation time is changed by changing the resistance component of the CR time constant circuit.

Now, such a delayed extinguishing function is used when it is desired to keep the present lighting state for a while after the extinguishing operation is performed, and is particularly used at bedtime and when going out. Because when it suddenly gets dark from the full lighting state, the sudden change in brightness makes it difficult for the eyes to get used to the dark space immediately,
This is because not only the subsequent operation of the operator is very dangerous, but also the turning off operation feels uncomfortable.

Therefore, a fade-out type delayed light-off function has been developed in which the brightness gradually decreases after the light-off operation. With this function, it is possible to keep the current lighting state for a while even after the turning-off operation, and by gradually becoming dark, the lighting is turned off after a predetermined time without giving a feeling of strangeness to the atmosphere in the room.

[0005]

However, there are two types of light-off states by the delayed light-off function, that is, a state where the night light is on and a state where all the light sources are off, and the light-off state differs depending on the lighting equipment. It was Lighting fixtures with such a delayed light-off function are mainly used in homes, and the fixtures installed in the living room are required to have the function of fading out from the fully-lit state to the fully-lighted-off state at bedtime. It is required that the fixtures have a function of delaying the lights from the all-lit state to the all-night light lit state when going out. That is, the purpose of use differs depending on the living space in which the lighting fixture is installed, and it is necessary for the user to be able to select the light-off state of the delayed light-off function.

The present invention solves the above problems.
It is an object of the present invention to propose a lighting device with a delayed light-off function that allows a user to select the light-off state of the delayed light-off function according to the purpose of use.

[0007]

In order to achieve the above object, the present invention uses a fluorescent lamp and a night light as a light source, and has a delayed lighting function in which the fluorescent lamp is turned off after a predetermined time has passed from the turning-off operation. In the above, there is provided a lighting fixture with a delayed light-off function, comprising a switch capable of selecting the light-off state from two types of states, a night-light lighting state and a night-light turning-off state.

[0008]

The user selects the light-off state by the delayed light-off function with the selectable switch, so that the night-light-on state or the night-light-off state can be selected depending on the purpose of use from the two types of light-on state after a predetermined time from the light-off operation. Become.
