Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a disaster prevention lighting device that lights up during a power outage for disaster prevention, and more specifically, the present invention relates to a disaster prevention lighting device that lights up during a power outage for disaster prevention. The present invention relates to a disaster prevention lighting device that automatically turns on a lighting lamp whose luminous flux when turned on from an off state during a power outage is larger than its luminous flux for disaster prevention in the event of a power outage.

(Prior Art) In this type of disaster prevention lighting system, when a lighting lamp such as a CFL containing amalgam is used, due to the characteristics of the lighting lamp, there are two cases in which the lighting changes from a normally lit state to a power outage, and from a non-lit state to a power outage. The luminous flux of the illumination lamp is different when it is turned on, and there is a phenomenon in which the luminous flux when the illumination lamp is turned on from the unlit state during a power outage is larger than the luminous flux when the illumination lamp is turned on during a power outage from a normally lit state.

In addition, such disaster prevention lighting equipment is normally specified to illuminate at 36% of the rated value, but in the power outage lighting state with less luminous flux mentioned above, that is, in the case of a power outage lighting from the normal lighting state. If the luminous flux of the illumination lamp is designed to be 36%, the battery will be wasted in the case where the luminous flux is larger when the other illuminating lamp is turned on due to a power outage.

Figure 2 clearly shows this relationship, and as shown by curve (A) in the figure, the design was designed so that the power is turned off from the normal lighting state with 100% luminous flux to 36% power outage. If the disaster prevention lighting device is turned on during a power outage from the 0% off state, the luminous flux will be 4 to 5% greater than 36%, as shown by the curve (b).

(Problems to be Solved by the Invention) As mentioned above, in a lighting lamp, the luminous flux when turned on from a normally lit state due to a power outage is greater than the luminous flux when turned on from a normally lit state due to a power outage. , 36%
If the lamp is designed to be turned on during a power outage, there is a problem in that when the lamp is turned on after a power outage from an off state, the luminous flux will increase by several percent and the battery will be wasted.

The present invention has been made in view of the above, and its purpose is to ensure that even when the lights are turned on during a power outage from either the normally lit state or the off state, the luminous flux is maintained at a specified level, and power is not wasted. An object of the present invention is to provide a disaster prevention lighting device that lights up lighting lights.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the disaster prevention lighting device of the present invention is a lighting device that has a luminous flux that is larger when the light is turned on from a non-lighted state due to a power outage than when the light is turned on during a power outage from a normally lit state.

first lighting control means for controlling the lighting lamp to turn on while heating the filament when the power outage detection means detects a power outage when the normal lighting detection means does not detect a normal lighting state; When the power failure detection means detects a power outage while the normal lighting detection means detects the normal lighting state, the lighting lamp is turned on by the heating power without heating the filament so as to supplement the luminous flux. The gist of the present invention is to include a second lighting control means for controlling the lighting.

(Function) In the disaster prevention lighting device of the present invention, when a power outage occurs when the lighting device is not in the normally lit state, the lighting lamp is turned on while heating the filament, and when a power outage occurs while the lighting device is in the normally lit state, the lighting lamp is turned on without heating the filament. Lights are turned on to compensate for the heating power used to supplement the luminous flux.

The operation of the disaster prevention lighting device configured as above will be explained next.

This disaster prevention lighting system has multiple states, including an off state, an off state to a power outage lighting state, a regular lighting state, and a regular lighting state to a power outage lighting state. , when commercial power is normally applied to the input terminals TMI and TM2 and the switch SW is not turned on, in the normal off state, the commercial power is applied to the power failure detection relay RY connected to both ends of the input terminals TM1 and TM2. At the same time, the commercial power source is transformed by the transformer T1, then rectified by the rectifier circuit RE1, and a predetermined DC voltage is outputted to the output of the rectifier circuit REI. In this state, when the power failure detection relay RY is activated, the break contact CY1 of the power failure detection relay RY connected to the output of the rectifier circuit REI is opened as shown by the dotted line, and the DC output voltage from the rectifier circuit REI is is not supplied to the inverter IV, but is supplied to the battery BT to charge it. In this off state, the inverter IV does not operate due to the opening of the contact CYI of the power failure detection relay RY, and the switch SW is also open, so the lighting lamp LP does not light up. In addition, in each contact CY1 to contact CY5 of the power failure detection relay RY, the state of each contact indicated by the dotted line is not a power failure state, and commercial power is normally supplied to the input terminals TMI and TM2, so that the power failure detection relay RY This shows the operating status when the is in operation.

Next, a power outage occurs from the above-mentioned off state, and the input terminal TM
I, assuming that commercial power is no longer supplied to TM2,
Since the power failure detection relay RY is turned off, the break contact CY1 of the power failure detection relay RY changes from the open state shown by the dotted line to the closed state shown by the solid line, and the DC voltage from the battery BT is applied to the inverter IV. The voltage is supplied to the inverter IV to operate, and a predetermined high-frequency voltage is generated from each secondary winding of the transformer T2 of the inverter IV. As a result, the voltage from the second secondary winding S2 of transformer T2 is equal to the voltage from said first secondary winding S1
From the upper end through the capacitor C7, the break contact CY2 of the power failure detection relay RY, the break contact CXI of the normal lighting state detection relay RX, and from the lower end of the second secondary winding S2 to the break contact CY3 of the power failure detection relay RY. The voltage from the first secondary winding S1 of the transformer T2 is supplied between the terminals 3 and 1 of the lighting lamp LP via the upper end of the first secondary winding S1 to the power failure detection relay. It is supplied between the terminals 1 and 2 of the lighting lamp LP via the break contact CY3 of the RY and the lower end of the second secondary winding S2, the capacitor C6, and the break contact CY4 of the power failure detection relay RY. The voltage from the third secondary winding S3 of the
from the upper end of the secondary winding S3 to the break contact CY4 of the power failure detection relay RY, and from the lower end of the third secondary winding S3 to the capacitor C5, the break contact CY5 of the power failure detection relay RY, and the normal lighting state detection. The light is supplied between terminals 2 and 4 of the lighting lamp LP via the break contact CX2 of the relay RX, so that the lighting lamp LP lights up with 36% luminous flux while the filament is heated.

Next, the regular lighting state will be explained. The normal lighting state is a state in which commercial power is supplied to the input terminals TMI and TM2, and the switch SW is turned on while the power failure detection relay RY is operating, thereby lighting the lighting lamp LP. In this case, when the power failure detection relay RY is activated, the break contact CYI of the power failure detection relay RY is opened as shown by the dotted line, and as a result, the inverter IV is not activated.
The battery BT is charged with the DC output voltage from the rectifier circuit REI.

When the switch SW is turned on while commercial power is being supplied to the input terminals TMI and TM2, the commercial power is transferred from the input terminal TMI to the switch SW and the ballast BA to the primary transformer T3 of the normal lighting state detection circuit SC. After passing through the winding, and passing through the next winding, the make contact CY2 of the power failure detection relay RY shown by the dotted line and the normal lighting state detection relay RX are connected.
The terminal 3 is connected to the terminal 3 of the lighting lamp LP via the break contact CXI of the lighting lamp LP, and the terminal 4 of the lighting lamp LP is connected to the break contact CX2 of the normal lighting state detection relay RX and the power failure detection relay. RY make contact C
The illumination lamp LP is normally turned on via a route that passes through Y5 and reaches the input terminal TM2. At this time, the lamp LN connected in parallel between the terminals 1 and 2 of the illumination lamp LP via the make contact CY4 is also lit.

In this normal lighting state, commercial power is supplied to the transformer T3 of the normal lighting state detection circuit SC through the above-mentioned path, so that a voltage is generated on the secondary side of the transformer T3, and this voltage is transferred to the rectifier. rectified by BR, capacitor C1
DC voltage is charged across both ends. The DC voltage from both ends of this capacitor C1 is supplied to one input of an AND circuit AN. By the way, the other input of this AND circuit AN is the break contact CYI of the power failure detection relay RY connected to the output of the rectifier circuit REI.
DC voltage passed through the battery BT, specifically as described later
However, in this normally lit state, the contact CY3 of the power failure detection relay RY is open as shown by the dotted line, so no DC voltage is supplied to the other input of the AND circuit AN. Therefore, in the normal lighting state, the output of the AND circuit AN is at a low level.

Therefore, the transistor T at the output of the AND circuit AN
r is also off, and the regular lighting state detection relay RX driven by the transistor Tr is also off.

In the above-mentioned normal lighting state, if a power outage occurs, the power outage detection relay RY is turned off, so the break contact CYI of the power outage detection relay RY is closed as shown by the solid line, and this causes the DC voltage of the battery BT to decrease. is supplied to inverter JV, inverter IV operates, and battery BT
The DC voltage is the AND circuit A of the normal lighting state detection circuit SC.
Also supplied to the other input of N. In this case, due to a power outage in the commercial power supply, the regular lighting state detection circuit SC
However, since the capacitor C1 of the normal lighting state detection circuit SC remains charged with DC voltage for a predetermined time, the DC voltage of this capacitor C1 is applied to one input of the AND circuit AN. As a result, the output of the AND circuit AN becomes high level, the transistor T is turned on, and the normal lighting state detection relay RX is activated.The normal lighting state detection relay RX
Once activated, it is self-held by its make contact CX3, and a power outage from the normal lighting state can be clearly determined by the operation of the normal lighting state detection relay RX.

As described above, when the regular lighting state detection relay RX is activated, the voltage from each secondary winding of the transformer T2 of the inverter IV is supplied to the lighting lamp LP as follows. That is, the voltage from the second secondary winding 1182 of transformer T2 is:
Since the break contact CXI of the normal lighting state detection relay RX in the path extending from the upper end of the second secondary winding S2 through the capacitor C7 to the terminal 3 of the lighting lamp LP is open, the lighting The light will not be supplied to the lamp LP.

Also, the voltage from the third secondary winding s3 of transformer T2 is
Since the break contact CX2 of the normal lighting state detection relay RX in the path extending from the lower end of the third secondary winding S3 through the capacitor C5 to the terminal 4 of the lighting lamp LP is open, the lighting The light will not be supplied to the lamp LP. The voltage from the first secondary winding S of transformer T2 is then:
From the upper end of the first secondary winding S1 to the power failure detection relay RY
and from the lower end of the first secondary winding S1 to the capacitor c6, the power failure detection relay RY
terminals 1 and 2 of the lighting lamp LP via the break contact CY4 of
The lighting lamp LP is supplied with a luminous flux of approximately 36%, thereby lighting the illumination lamp LP with approximately 36% of the luminous flux without supplementing the luminous flux by cutting the filament heating power and increasing the heating power bone lamp current. .

That is, when the light is turned on from the off state due to a power outage, the voltage from the second secondary winding S2 and the third secondary winding S3 of the transformer T2 is transferred to the terminals 1, 3 and 2 of the lighting lamp LP. 4
At the same time, the voltage from the first secondary winding S1 of the transformer T2 is supplied between the terminals 1 and 2 of the lighting lamp LP to light the lighting lamp LP, thereby heating the lighting lamp LP. % of the luminous flux, but when the power is turned off from the normal lighting state, the voltage from the second secondary winding S2 and the third secondary winding s3 of the transformer T2 is turned on. By not supplying light between terminals 1 and 3 and terminals 2 and 4 of the lamp LP, the amount of filament heating is cut, and
The voltage from the first secondary winding S1 of the transformer T2 is applied to the lamp L.
P is supplied between terminals 1 and 2 of P, thereby increasing the lamp current by the amount of filament heating and supplementing the luminous flux to approximately 36
% of the luminous flux. Note that this type of illumination lamp LP has constant voltage characteristics, and by cutting filament heating, the amount of electric power for emitting light increases, which can be supplemented to increase the luminous flux.

[Effects of the Invention] As explained above, according to the present invention, when a power outage occurs when the lighting is not in the regular lighting state, the illumination lamp is turned on while heating the filament, and when a power outage occurs while the lighting is in the regular lighting state, the filament is turned on. Since the lighting lamps with the heating power are turned on without heating to supplement the luminous flux, if the lights are turned on during a power outage from the off state, which is not the normally lit state, the specified luminous flux will be satisfied and the luminous flux will be returned to the normally lit state. In the event of a power outage, the filament is not heated and the luminous flux is supplemented to almost satisfy the specified luminous flux, preventing unnecessary power consumption and increasing efficiency.
