Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighting device having two or more non-music light sources in addition to a regular light source.

Generally, this type of lighting device uses a backup DC power source to light the lamp during a power outage of the AC power source.

However, if that particular emergency lamp is defective due to the end of its life or other reasons, it will not be able to provide emergency illumination, and the original function as disaster prevention lighting will not be achieved, which is dangerous.

The present invention has been developed to eliminate the above-mentioned drawbacks, and when the lamp used as an emergency lighting light source is defective and does not turn on, another lamp is automatically turned on in its place. ing.

Hereinafter, the present invention will be specifically explained based on the drawings.

The lighting device 1//'i of the present invention, as shown in the figure, a regular lighting device 2, an emergency lighting device 4, lamps 5□, 52 as two or more light sources for common use and emergency use, a first switching It consists of a device 6 and a second switching device 7.

The regular lighting device 2 receives the AC power source 3 as an input, and is configured with a ballast for lighting the lamps 5□, 52 of discharge lamps, for example.

The emergency lighting device 4 receives the AC power supply 3 as an input and is used to supply power to either of the lamps 5□, 5° in an emergency, and includes a charging device 8, a storage battery 9, and a high frequency generator 10.
It consists of

The charging device 3 constantly charges the storage battery 9 with the AC power source 3 during normal operation.

The high-frequency generator 10 generates high-frequency waves using the storage battery 9 as a power source in order to light up the discharge lamps as the lamps 5□ and 52 in an emergency.

The first switching device 6 is a device that connects the emergency lighting device 4 to the lamp 5□ or 5° instead of the regular lighting device 2 in the event of a power outage of the AC power source 3.
Contact point 11 in the circuit with one lamp 5□. Contact point 1 present in the circuit between button, storage battery 9 and high frequency generator 10
Operate 2.

The second switching device 7, which has been switched off, detects the lamp current, lamp voltage, presence or absence of light, etc. of one lamp 5□ mainly during emergency lighting, and switches when the current is not present. 15 to switch the contacts 16 from one side to the other.

Next, the operation will be explained.

In a normal state where the AC power source 3 is input, the first switching device 6 receives the AC power source 3, opens the contact 12, and places the contact 11 on the a side.

The second switching device 7 in the housing similarly connects the contact 16 to a
switching to the side.

Therefore, in this normal time, the regular lighting device 2 is
All of the two lamps 50, 5□ will be lit.

Further, the charging device 8 charges the storage battery 9 using the AC power source 3 during normal times, and prepares for an emergency.

Since the button and contact 12 are open, the high frequency generator 10
doesn't work.

Next, when the AC power supply 3 is cut off and an emergency state occurs, the first switching device 6 closes the contact 12 and closes the contact 11.
switch to side b.

For this reason, the high frequency generator 10 turns on one lamp 5□ in an emergency.

Here, if the lamp 5□ is not lit, the lamp current as -fu to be detected will not flow through the measuring section 13, so the second switching device 7 detects this and switches the contact 16 to b. switch to the side.

Therefore, lamp 5° is automatically turned on instead of lamp 5□.

This button, this second switching device 7, detects the condition even when the lamp 5□ lights up intermittently due to a defect such as lifespan during normal lighting, and forcibly switches the power supply to this lamp 5. Works to stop it.

Therefore, defective flashing and the like can be prevented and management thereof becomes easy.

According to the present invention, if one of the two or more lamps serving as a light source breaks down in an emergency, the other lamps will dynamically turn on in its place, reducing the number of non-lighting accidents during emergencies. Therefore, there is an advantage that the function as an emergency lighting device and a guidance lighting device is enhanced.
