Description

In the invention of claim 3, it is determined that the received vibration is greater than or equal to the vibration at the time of the earthquake, and at that time, even if there is no other light source around the LED lighting device, it receives electric power from the outside. The power is supplied to all of the plurality of white LEDs. Therefore, when there is no power failure even during a nighttime earthquake, a plurality of white LEDs are automatically turned on automatically in the same way as during normal times, and therefore can be illuminated brightly as an emergency light.
In the invention of claim 4, in the normal state, the plurality of white LEDs are lit by receiving power supply, while (1) all LEDs are turned off without any external power supply due to a power failure at night. When there is no other light source around the lighting device, that is, when the surroundings of the LED lighting device are in a dark state, some of the white LEDs are supplied with auxiliary power from the auxiliary power supply means. Light. In addition, normally, a plurality of white LEDs are lit by receiving power supply, while (2) it is determined that the received vibration is more than the vibration at the time of the earthquake, and at that time the surroundings of the LED lighting device are When there is no other light source, that is, in the event of an emergency such as an earthquake at night, some white LEDs among the plurality of white LEDs are lit by receiving auxiliary power from the auxiliary power supply means. Therefore, in addition to functioning as a lighting device in normal times, as shown in (1) and (2), some of the white LEDs are automatically turned on in the event of a power outage or earthquake at night. It can also function as an emergency light. In this case, since only a part of the white LED is lit, the user of the LED lighting device is informed that it is not in a normal lighting state (white LED is fully lit), that is, an emergency. be able to.

In the invention of claim 5 , when there is no other light source around the LED lighting device, such as at night, a plurality of whites that have been turned off until then when a person approaches the LED lighting device within a predetermined range. Since the LED is turned on in response to the supply of power or auxiliary power, for example, it is possible to respond to emergency needs such as the need for light after going to bed at night. Therefore, it is possible to provide a function suitable for needs for ordinary houses as compared to a normal emergency light that is turned on only in an emergency. Note that auxiliary power may be supplied to only some of the white LEDs. Thereby, since the LED lighting device does not suddenly turn on and suddenly brightens from the dark state when it is completely turned off, it is possible to make it difficult for the user of the LED lighting device to feel discomfort due to glare. .

In the invention of claim 6 , it is possible to notify the user of the LED lighting device of a situation different from the normal lighting state in which the white lighting is performed. Therefore, the occurrence of an emergency state can be notified to the user.

According to the seventh aspect of the invention, in the normal state, the auxiliary power supply means can be charged by receiving external power. Further, the auxiliary power supply means can be charged by receiving power generated by irradiating the solar cell with illumination light or external light from the LED illumination device.
