Description

  The present invention relates to, for example, an emergency light combined stairway guide light.

  There are guide light fixtures installed on stairs and passages in buildings and offices. This guide light fixture is provided on a stairway, an inclined road, or the like serving as an evacuation route, and gives illuminance effective for evacuation to the floor even during a power failure, and is referred to as a stairway guide light.

  There is also an emergency lighting fixture having an emergency light source that is turned on by an emergency power source in the event of a power failure. If an emergency lighting fixture is installed, there is no need to install a guide light. A stairway guide light that also functions as an emergency lighting fixture is also called an emergency light combined stairway guide light. The

Here, there are the following three types of emergency lighting fixtures.
(1) There are dedicated emergency lighting fixtures that have only an emergency light source that does not light during normal times. For example, there is a small one that turns on a mini halogen lamp (see Patent Document 1).
(2) There is a built-in emergency lighting apparatus having both a light source that is turned on only by a general power source and an emergency light source that is not turned on in normal times. For example, a fluorescent lamp is used as a light source that is lit by a general power source, and a mini halogen lamp is used as an emergency light source (see Patent Document 2).
(3) There is a combined emergency lighting apparatus having an emergency light source that is lit by a general power source. For example, there is one that uses a fluorescent lamp as an emergency light source that is lit even with a general power supply (see Patent Document 3).

  The emergency light and stairway guide light does not light during normal times because it is necessary to take a wide range of lights such as stairs and landings during normal times. (1) It is not a dedicated emergency lighting fixture. (2) Built-in type Either an emergency lighting fixture or (3) a combined emergency lighting fixture is used.

  Moreover, there is a night light used for safety and crime prevention purposes (see Patent Document 4).

The emergency light combined stairway guide light is a lighting fixture for disaster prevention that is installed at stairs landings, etc. It functions as a normal lighting fixture during regular use, and evacuees can evacuate safely and quickly during power outages, etc. It is intended to guide you. In order to meet the requirements for emergency lights, the emergency light combined stairway guide light must be at least 1 lux when the light source is a light bulb (2 lux when the light source is a fluorescent lamp) so that evacuation can be performed even if a power failure occurs Designed to ensure illuminance.

  Hereinafter, the normal time is a state in which a normal power source (commercial power source) is in operation, and the time of power failure or emergency means a state in which the normal power source (commercial power source) is stopped.

  1A and 1B are schematic views showing a lighting fixture 100a according to the present embodiment, in which FIG. 1A is a front view with a sealing cover 110 removed, and FIG. 1B is a side sectional view. FIG. 2 is a circuit diagram of a built-in emergency lighting fixture 800 for comparison. FIG. 3 is a circuit diagram of lighting fixture 100a according to the present embodiment. The circuit configuration of the lighting fixture 100a according to the present embodiment will be described with reference to FIGS.

  As illustrated in FIG. 1, the lighting fixture 100a (lighting device) includes a fixture main body 120, a first light emitting member 180 including LED modules 180a to 180d, a second light emitting member 190, and a sealing cover 110.

  The LED modules 180a to 180d are LED substrates on which LEDs (light emitting diodes) are mounted as light sources 182 on the light emitting surface 181 of the substrate, for example. As shown in FIG. 1A, the first light emitting member 180 including the four LED modules 180a to 180d is arranged so that each LED module forms one side of a quadrangle, and is arranged so as to form a quadrangle as a whole. Has been.

  As shown in FIG. 1A, five light sources 182 (LEDs) are mounted side by side on the light emitting surface 181 of the substrate in the LED modules 180 a and 180 c arranged along the vertical direction. Five light sources 182 (LEDs) are also mounted side by side on the substrate in the LED modules 180b and 180d arranged in a direction perpendicular to the vertical direction.

  As shown in FIGS. 1A and 1B, the LED modules 180a to 180d are arranged on the instrument main body 120 so that the light emitting surfaces 181a to 181d face the front direction. The first light emitting member 180 (LED modules 180a to 180d) is a light source for giving illuminance to the vicinity of a stair landing or passage around the staircase during normal use.

  For example, four light sources 192 (LEDs) are mounted side by side on the light emitting surface 191 of the substrate.

  The second light emitting member 190 is disposed on the lower side (floor surface side) of the first light emitting member 180 (LED modules 180a to 180d). As shown in FIGS. 1A and 1B, the second light emitting member 190 is disposed on the floor surface side of the LED module 180b substantially parallel to the LED module 180b.

  The second light emitting member 190 is arranged so that the light emitting surface 191 faces the floor surface direction (downward) instead of the front direction. The second light emitting member 190 arranged so that the light emitting surface 191 faces the floor surface is an emergency light source that is turned on using a secondary battery 140 (battery), which will be described later, as a power source at the time of a power failure. This is a light source that enables safe and quick evacuation behavior.

  The instrument main body 120 has a light source mounting surface to which the first light emitting member 180 and the second light emitting member 190 are attached. Further, a lighting device including a terminal block 170, a switching power supply 212, a charging circuit 150a, a control circuit 150c, and the like, which will be described later, is housed inside the fixture body 120 (not shown).

  FIG. 2 is a circuit diagram of a built-in emergency lighting fixture 800 which is a comparative example of the lighting fixture 100a according to the present embodiment.

  The built-in emergency lighting device 800 includes a service ballast 830, a secondary battery 840, a control unit 850, an inspection switch 860, a terminal block 870, a main light source 880, and an emergency light source 890. The built-in emergency lighting fixture 800 is supplied with power from the regular power source 910 via the terminal block 870. The main light source 880 is, for example, a fluorescent lamp. The emergency light source 890 is, for example, a mini halogen lamp.

  The regular ballast 830 turns on the fluorescent lamp, which is the main light source 880, during normal use, for example, by converting the alternating voltage from the regular power supply 910 into a direct voltage. The regular ballast 830 is connected to a terminal c and a terminal b connected to the regular power supply 910, and is composed of the regular power supply 910, the terminal c, the regular ballast 830, the main light source 880, the regular ballast 830, and the terminal b. A loop of power supply 910 is formed. From this loop, the service ballast 830 turns on the fluorescent lamp, which is the main light source 880, using the service power supply 910 as a power supply during service.

  Since the terminal b of the terminal block 870 is connected to the utility power source 910 via the wall switch 911 (remote control switch), the power of the utility power source 910 is supplied to the service ballast 830 when the wall switch 911 is turned off. First, the main light source 880 is turned off.

  The control unit 850 includes a charging circuit 850a and a switching control circuit 850b. The control unit 850 is connected to the terminal c and the terminal a connected to the normal power source 910. In normal use, the control unit 850 includes the normal power source 910, the terminal c, the control unit 850, the secondary battery 840, the control unit 850, and the terminal a. A loop of the regular power source 910 is formed. From this loop, the control unit 850 charges the secondary battery 840 using the normal power source 910 as a power source during normal use.

  At the time of power failure, the control unit 850 turns on the emergency light source 890 using the secondary battery 840 as a power source.

  The charging circuit 850a supplies the DC voltage to the switching control circuit 850b by converting the AC voltage from the regular power source 910 into a DC voltage.

  The switching control circuit 850b charges the secondary battery 840 when the utility power source 910 is present, and when the utility power source 910 stops and enters a power failure state, an emergency light source 890 (mini-halogen lamp) is generated by the power of the secondary battery 840. Lights up.

  The inspection switch 860 is a switch for simulating the operation at the time of a power failure (emergency) and checking whether the emergency light source 890 is turned on at the time of a power failure. The inspection switch 860 is disposed between the terminal c and the service ballast 830 and the control unit 850. By turning off the inspection switch 860, the supply of power to the service ballast 830 and the control unit 850 can be cut off in a simulated manner.

  As shown in FIG. 2, when the wall switch 911 is turned off, the loop composed of the common power source 910, the terminal c, and the common ballast 830 is cut, and the main light source 880 is turned off. Even when the wall switch 911 is turned off, there is no effect on the loop composed of the normal power source 910, the terminal c, the control unit 850, the emergency light source 890, and the control unit 850, and the emergency light source 890 remains off, and the secondary The battery 840 continues to be charged.

  As described above, the built-in emergency lighting device 800 does not function as a night light if it is turned off by the wall switch 911 or the like, for example, at night or when no person is present. In addition, for example, even if it is configured to be turned on when there is a person by combining a human sensor or the like, it is a fluorescent lamp that is turned on and is not intended for a night light, but is satisfactory from the viewpoint of energy saving is not. In addition, mini-halogen lamps are unsuitable for use as light sources for night lights because of their short lifetime.

  Next, the circuit configuration of the lighting fixture 100a according to the present embodiment will be described with reference to FIG.

  The lighting fixture 100a includes a secondary battery 140, a charging circuit 150a, a control circuit 150c, an emergency lighting circuit 150d, an inspection switch 160, a terminal block 170, a first light emitting member 180, a second light emitting member 190, a switching power supply 112, 1 switch 131, second switch 132, turn-off detection circuit 115, brightness setting circuit 117, and brightness sensor 119.

  The switching power supply 112 is a switching converter provided with, for example, an insulating flyback circuit.

  The control circuit 150c incorporates a microcomputer and controls the entire circuit of the lighting fixture 100a. The charging circuit 150 a is supplied with power from the switching power supply 112 and charges the secondary battery 140.

  The first switch 131 is electrically connected in parallel to the first light emitting member 180, and the second switch 132 is electrically connected in parallel to the second light emitting member 190. The third switch 133 is electrically connected so that the switching power supply 112 can be disconnected from the first light emitting member 180 and the second light emitting member 190.

  The inspection switch 160 is connected to the control circuit 150c and is an inspection switch for simulating a circuit of the lighting fixture 100a in a power failure state. For example, if the control circuit 150c detects that the inspection switch 160 is turned on and controls the switching power supply 112 to stop, it is possible to simulate a power failure without shutting off the regular power supply 910. The state can be confirmed.

  Thereby, the user can check whether the lighting fixture 100a operates correctly in an emergency. The inspection switch 160 may be operable by a remote control, for example.

  The emergency lighting circuit 150d is a circuit that operates so that the second light emitting member 190 that is lit in an emergency can be appropriately lit, for example, by boosting the voltage of the secondary battery 140.

  A wall switch 911 is disposed between the regular power source 910 and the terminal b of the terminal block 170. For example, the wall switch 911 may be operated by remote control.

  The extinction detection circuit 115 is connected to the terminal b of the terminal block 170 and detects the on state or the off state of the wall switch 911.

  When the turn-off detection circuit 115 detects that the wall switch 911 is turned on, it outputs a turn-on detection signal to the control circuit 150c. In addition, when the turn-off detection circuit 115 detects that the wall switch 911 is turned off, the turn-off detection circuit 115 outputs a turn-off detection signal to the control circuit 150c.

  The light-off detection circuit 115 outputs a light-on detection signal when detecting that the wall switch is turned on (lighting request) during normal use, and detects that the wall switch is turned off (light-off request) during normal use. In this case, the detection circuit outputs a turn-off detection signal.

  The brightness setting circuit 117 is a circuit that sets the brightness of the second light emitting member 190 that functions as a nightlight.

  The brightness sensor 119 is a sensor that detects the brightness around the lighting apparatus 100a. For example, the brightness sensor 119 detects ambient brightness and outputs a brightness detection signal indicating brightness to the control circuit 150c. The control circuit 150c detects nighttime or the like based on the brightness detection signal from the brightness sensor 119.

  Next, the operation | movement at the time of normal use of the circuit of the lighting fixture 100a is demonstrated using FIG.

  When the lighting detection signal is input from the extinction detection circuit 115, the control circuit 150c (lighting control circuit) performs control so that electric power is supplied from the regular power source 910 to the first light emitting member 180, and the first light emission. The member 180 is turned on, and the second light emitting member 190 is turned off by controlling the power supply 910 not to supply power to the second light emitting member 190, so that power is supplied from the normal power supply 910 to the charging circuit 150a. To charge the secondary battery 140.

  During normal use, power is supplied to the circuit of the lighting fixture 100a from the normal power supply 910 via the terminal block 170. The normal power supply 910 is applied to the terminals c and a of the terminal block 170, and the switching power supply 112 operates.

  The control circuit 150c is supplied with power from the switching power supply 112 during normal use. The control circuit 150c controls the first switch 131 to be turned off and the second switch 132 to be turned on. With this control, power is supplied from the switching power supply 112 to the first light emitting member 180, but power is not supplied from the switching power supply 112 to the second light emitting member 190.

  That is, during normal use, a closed loop returning to the switching power source 112, the first light emitting member 180, the second switch 132, and the switching power source 112 is formed, and only the first light emitting member 180 is lit.

  On the other hand, the output of the switching power supply 112 also supplies power to the charging circuit 150a, and the charging circuit 150a charges the secondary battery 140.

  Next, the operation | movement at the time of a power failure of the circuit of the lighting fixture 100a is demonstrated using FIG.

  First, when power is not supplied from the regular power supply 910 due to a power failure or the like, the switching power supply 112 stops. Since the switching power supply 112 is operated by the power from the normal power supply 910, the control circuit 150c determines whether or not a power failure is caused by the operation of the switching power supply 112 (including the oscillation stop state of the switching circuit). Alternatively, a power failure detection circuit that directly determines whether power is supplied from the regular power source 910 may be added, and the control circuit 150c may be configured to detect a power failure based on a signal from the power failure detection circuit. .

  When the power failure is detected, the control circuit 150c (power failure control circuit) receives power from the secondary battery 140. Then, the control circuit 150c (power failure control circuit) controls the emergency lighting circuit 150d to receive power supply from the secondary battery 140.

  The emergency lighting circuit 150d (first emergency lighting circuit) lights the second light emitting member 190 using the secondary battery 140 as a power source.

  That is, when the normal power supply 910 is cut off and a power failure occurs, the switching power supply 112 stops, so power is supplied from the secondary battery 140 to the control circuit 150c, and the emergency lighting circuit 150d is operated by the control circuit 150c.

  The control circuit 150c controls the first switch 131 to be on and the second switch 132 to be off. By this control, a closed loop of the emergency lighting circuit 150d, the first switch 131, the second light emitting member 190, and the emergency lighting circuit 150d is formed, and only the second light emitting member 190 is turned on by the power source of the secondary battery 140. .

  At this time, the brightness of the second light emitting member 190 is set in advance in the emergency lighting circuit 150d so as to ensure a range of brightness determined by law as an emergency light. That is, when the second light emitting member 190 functions as an emergency light during a power failure, it is desirable that the brightness cannot be set from the outside.

  Next, the operation of the circuit of the lighting fixture 100a when the wall switch 911 is turned off will be described. When the wall switch 911 is turned off, the extinction detection signal is output from the extinction detection circuit 115 to the control circuit 150c as described above.

  The control circuit 150c (control circuit at the time of extinction) controls the first light emitting member by controlling so that power is not supplied from the regular power source 910 to the first light emitting member 180 when the extinction detection signal is input from the extinction detection circuit 115. 180 is turned off. Further, the control circuit 150c (control circuit at the time of extinction) controls the electric power to be supplied from the regular power source 910 to the second light emitting member 190 to turn on the second light emitting member 190. Further, the control circuit 150c (control circuit at the time of extinction) charges the secondary battery 140 by controlling so that power is supplied from the regular power source 910 to the charging circuit 150a.

  The terminal b of the terminal block 170 is connected to the regular power source 910 via a wall switch 911 (which may be a remote control switch). The light extinction detection circuit 115 detects that the signal between the terminal b and the common power source 910 is cut off, and outputs a light extinction detection signal to the control circuit 150c (microcomputer).

  When the extinction detection signal is input, the control circuit 150c turns off the third switch 133, stops the power supply to the first light emitting member 180 and the second light emitting member 190, and the secondary battery 140 It is also possible to control to continue only charging.

  However, in order to cause the second light emitting member 190 to function as a night light, the control circuit 150c receives a turn-off detection signal and stops the power supply to the first light emitting member 180 and the second light emitting member 190. The switch 133 is not turned off. The control circuit 150c controls the first switch 131 on and the second switch 132 off while the third switch 133 remains on.

  When the circuit of the lighting fixture 100a is controlled to turn on the first switch 131 and turn off the second switch 132, the first light emitting member 180 is turned off and only the second light emitting member 190 is turned on. Thereby, the 2nd light emission member 190 can be functioned as a nightlight.

  The brightness setting circuit 117 is a circuit that sets the brightness of the second light-emitting member 190 when the second light-emitting member 190 is turned on as a nightlight with respect to the control circuit 150c. The brightness setting circuit 117 inputs the set brightness as a brightness setting signal to the control circuit 150c.

  The control circuit 150c controls the brightness of the second light emitting member 190 functioning as a night light by controlling the output of the switching power supply 112 in accordance with the brightness setting signal input from the brightness setting circuit 117.

  For example, the brightness setting circuit 117 may be set in advance with brightness when the second light emitting member 190 is lit as a night light. Or it is good also as a circuit which sets the brightness of a nightlight by the volume operation from the outside. Alternatively, it may be configured such that a circuit such as a change-over switch or the like can be continuously varied by performing control such as step dimming or sending a signal from the outside with a remote controller or the like.

  Further, the brightness of the night light of the second light emitting member 190 set in the brightness setting circuit 117 may be set by the administrator according to the installation location. For example, by increasing the brightness of the night light, it is possible to obtain sufficient brightness to go back and forth on the stairs without turning on the first light emitting member 180. In addition, by using an LED as the light source of the second light emitting member 190, it is possible to light for a long time with sufficient brightness without considering the life of the light source. By setting the brightness as a night light in this way, even if the wall switch 911 is turned off at night when there are few people, the night light alone is effective for safety and crime prevention, and energy can be saved.

  Alternatively, the brightness of the nightlight may be the specified brightness when lighting as an emergency light (minimum brightness required for evacuation as required by law) The brightness may be the same as that of the first light emitting member 180, or may be set to a modest brightness than that of the first light emitting member 180 during normal lighting.

  However, no matter how it is set, when the normal power source 910 is cut off and a power failure occurs, the emergency lighting circuit 150d operates and the second light emitting member 190 is turned on with the secondary battery 140 as a power source. Turn on the light at the specified brightness or higher.

  Next, the lighting variation of the circuit of the lighting fixture 100a in the case of causing the second light emitting member 190 to function as a nightlight will be described.

  According to the lighting fixture 100a in the present embodiment, even when the wall switch 911 is turned off, the switching power supply 112 is supplied with power from the normal power supply 910, and the control circuit 150c is supplied with power from the switching power supply. The control circuit 150c is operable.

  Further, since the turn-off detection circuit 115, the brightness setting circuit 117, and the brightness sensor 119 are connected to the control circuit 150c, the turn-off detection circuit 115, the brightness setting circuit 117, and the brightness are turned on even when the wall switch 911 is turned off. The length sensor 119 is operable by being supplied with power from the control circuit 150. Therefore, the following operation is also possible in the circuit of the lighting apparatus 100a.

  As described above, since the brightness sensor 119 can operate regardless of whether the wall switch 911 is on or off, the control circuit 150c performs control as follows based on the brightness detection signal input from the brightness sensor 119. You can also.

  When the nighttime is detected based on the brightness detection signal, the control circuit 150c may turn on the second light emitting member 190 as a nightlight regardless of whether the wall switch 911 is on or off. At this time, it is preferable that the brightness of the second light emitting member 190 as a nightlight is set to be higher than the brightness that can secure the brightness of the feet at night only by the nightlight.

  As described above, according to the lighting apparatus 100a, the first light emitting member 180 is automatically turned off and the second light emitting member 190 is automatically turned on in accordance with the brightness detected by the brightness sensor 119. This can save energy.

  As described above, according to the lighting fixture 100a according to the present embodiment, the signal of the wall switch 911 is input to the control circuit 150c as a signal for turning off (light-off detection signal), and the first light-emitting member is input by the control circuit 150c. This is a method for controlling 180 to be turned off. Therefore, by inputting the signal (brightness detection signal) detected by the brightness sensor 119 to the control circuit 150c, the control circuit 150c can perform a normal operation based on the brightness detection signal regardless of whether the wall switch 911 is on or off. The lighting, dimming, and extinguishing control of one light emitting member 180 can be performed.

  In order to make the most of the function as a night light in the lighting apparatus 100a, the priority order for determining the state of the wall switch 911, the brightness sensor 119, and the normal power source 910 in the control circuit 150c is the presence or absence of the normal power source> brightness sensor> wall switch. It is preferable that With this priority, the control circuit 150c can be used when a power failure occurs even if the wall switch 911 is off or the brightness sensor 119 is bright. In this case, the second light emitting member 190 is always turned on as an emergency light, and it is possible to ensure the brightness to evacuate smoothly in an emergency.

  As described above, according to the circuit configuration of the lighting fixture 100a according to the present embodiment, even when the wall switch 911 is turned off, the second light emitting member 190 can be turned on as a night light. Further, the second light emitting member 190 is used as a light source for lower surface (floor surface) light emission and can be turned on as a night light. Thereby, the function as a nightlight is added, and the lighting apparatus 100a having a function of illuminating the feet can be provided.

  In addition, since the second light emitting member 190 serving as an emergency light source is disposed separately from the first light emitting member 180 serving as a regular light source, the emergency secondary battery 140 can be made compact. In addition, since the second light emitting member 190 is disposed separately from the first light emitting member 180 as described above, it is not necessary to provide both a power source that is regularly lit during normal use and a power source that charges the secondary battery. 100a itself can also be comprised compactly.

Embodiment 2. FIG.
FIG. 4 is a circuit diagram of the lighting apparatus 100b according to the present embodiment. FIG. 4 is obtained by further adding a configuration to the circuit configuration of FIG. 3 described in the first embodiment. 4, components having the same functions as those in FIG. 3 are given the same reference numerals, and descriptions thereof are omitted.

  As shown in FIG. 4, the lighting fixture 100 b includes a human sensor 121. The human sensor 121 is built in the lighting fixture 100b and connected to the control circuit 151c. Similar to the extinction detection circuit 115, the brightness setting circuit 117, and the brightness sensor 119 described in Embodiment 1, the human sensor 121 is also supplied with power from the control circuit 150c, so even if the wall switch 911 is turned off. It is possible to operate.

  As shown in FIG. 4, the circuit of the lighting fixture 100b includes sense resistors 250e, 250f, and 250g (current adjustment circuit), a fourth switch 134, and a fifth switch 135.

  The fourth switch 134 is a switch for switching the sense resistor between normal use and emergency (power failure). The fifth switch 135 is a switch for dimming the first light emitting member 180 and the second light emitting member 190 when operating with the switching power supply 112. The sense resistor 250f is a sense resistor that is switched by the fifth switch 135.

  The operation of this embodiment will be described with reference to FIG. In this embodiment, a case where the lighting fixture 100b operates a circuit with a constant current will be described.

  In normal use, power is supplied to the circuit of the lighting fixture 100 b from the normal power supply 910 via the terminal block 170. The normal power supply 910 is applied to the terminals c and a of the terminal block 170, and the switching power supply 112 operates.

  When the control circuit 150c controls the first switch 131 to be turned off, the second switch 132 to be turned on, and the fourth switch 134 to be turned on, the switching power supply 112, the first light emitting member 180, the second switch 132, the fourth switch The switch 134, at least one of the sense resistors 250f and 250g, forms a closed loop of the switching power supply 112, and only the first light emitting member 180 is lit.

  In the circuit of the switching power supply 112, the voltage is detected by the combined resistance of the sense resistor 250f and the sense resistor 250e. The circuit of the switching power supply 112 is a constant current circuit using sense resistors 250f and 250g, and a sense voltage is set in the switching power supply 112. The switching power supply 112 passes a current through the circuit so that the sense voltage is maintained. Then, the control circuit 150c turns on and off the fifth switch 135 that is electrically connected in parallel to the sense resistor 250f, whereby the resistance value of the circuit changes and the current output from the switching power supply 112 is controlled and flows to the circuit. The current can be controlled.

  Thereby, the light control of the 1st light emission member 180 currently lighted by the power supply of the switching power supply 112 is attained at the time of normal use. If the second switch 132 is controlled to be turned off by the control circuit 150c, the second light emitting member 190 can be turned on, and the first light emitting member 180 and the second light emitting member 190 can be dimmed. . However, when dimming of the first light emitting member 180 and the second light emitting member 190 is possible, only the first light emitting member 180 and the second light emitting member 190 are dimmed at the same time. Can not.

  On the other hand, the output of the switching power supply 112 supplies power to the charging circuit 150 a and charges the secondary battery 140.

  If power is not supplied from the regular power supply 910 during a power failure, the switching power supply 112 stops. When the switching power supply 112 is stopped, the control circuit 150 c is supplied with power from the secondary battery 140. Then, the control circuit 150c controls the emergency lighting circuit 150d, and the emergency lighting circuit 150d lights the second light emitting member 190 by supplying the power of the secondary battery 140 to the second light emitting member 190.

  That is, when the normal power source 910 is cut off and the power failure occurs, the switching power source 112 stops, so that power is supplied from the secondary battery 140 to the control circuit 150c, and the emergency lighting circuit 150d is operated by the control circuit 150c.

  The control circuit 150c controls the first switch 131 to be on and the second switch 132 to be off. By this control, the emergency lighting circuit 150d, the first switch 131, the second light emitting member 190, at least one of the sense resistors 250e, 250f, and 250g, a closed loop of the emergency lighting circuit 150d is formed, and the secondary battery 140 is formed. As a power source, only the second light emitting member 190 is turned on.

  Since the closed loop (circuit) of the emergency lighting circuit 150d is a constant current circuit, a sense voltage is set in the emergency lighting circuit 150d. The emergency lighting circuit 150d supplies a current to the circuit so that the sense voltage is maintained. Therefore, by turning on and off the fourth switch 134 and the fifth switch 135 arranged in parallel with the sense resistor 250e and the sense resistor 250f by the control circuit 150c, the resistance value of the circuit changes, and the switching power supply 112 Is controlled, and the current flowing through the circuit can be controlled.

  Thereby, the light control of the 2nd light emission member 190 currently lighted by the emergency lighting circuit 150d at the time of a power failure is attained. If the first switch 131 is controlled to be turned off, the first light emitting member 180 can be turned on, and the first light emitting member 180 and the second light emitting member 190 can be dimmed. However, in this case, only the first light emitting member 180 and the second light emitting member 190 are dimmed at the same time, and cannot be dimmed individually.

  As shown in FIG. 4, the sense resistors 250f, 250e, and 250g are connected in series. Usually, in a circuit such as the switching power supply 112, a sense voltage for constant current feedback is set low (for example, 0.2 V) in order to reduce circuit loss. The sense voltage for the emergency lighting circuit 150d is about 0.2 to 1.5V.

  The current flowing through the circuit is larger during normal use than during a power failure. This is because the current for turning on the light source is larger during normal use. Therefore, the sense resistor is connected so that the resistance value of the circuit during normal use (the circuit of the switching power supply 112) is smaller than the resistance value of the circuit during the power failure (circuit of the emergency lighting circuit 150d).

  Specifically, the sense resistors 250e, 250f, and 250g are connected in this order. The switching power supply 112 detects the voltage on the upper side of the sense resistor 250f, and the emergency lighting circuit 150d detects the voltage on the upper side of the sense resistor 250e.

  By turning on and off the fourth switch 134 in accordance with the signal from the control circuit 150c, the value of the sense resistor for the switching power supply that operates during normal operation and the value of the sense resistor of the emergency lighting circuit 150d that operates during emergency operation can be varied. You can change the brightness. For example, during normal use, the control circuit 150c turns on the fourth switch 134 to lower the resistance value of the circuit of the switching power supply 112, and during a power failure, the control circuit 150c turns off the fourth switch 134 and turns off the switching power supply. The resistance value of the circuit 112 is increased.

  When the control circuit 150c turns on / off the fifth switch 135 during normal use, the switching power supply 112 can dimm the light emitting members (the first light emitting member 180 and the second light emitting member 190). The light emitting members (the first light emitting member 180 and the second light emitting member 190) are lit brighter when the fifth switch 135 is turned on. If the first light emitting member 180 and the second light emitting member 190 are turned on when the light is turned on, energy can be saved while ensuring brightness.

  The control circuit 150c controls the first switch 131 to be turned off and the second switch 132 to be turned off, so that the output of the switching power supply 112 is passed through the third switch 133, the first light emitting member 180 and the second light emitting element. The member 190 is turned on, and the current value sensed by the sense resistor 250g is fed back to the switching power source 112 via the fourth switch 134 and the fifth switch 135, and is lit for regular use. At this time, the first light-emitting member 180 and the second light-emitting member 190 can be dimmed and lighted by turning off the fifth switch 135 and setting it as a series combined resistance of the resistor 250f and the sense resistor 250g.

  Whether or not the first light emitting member 180 and the second light emitting member 190 are turned on can be selected by operating the first switch 131 and the second switch 132 with the control circuit 150c.

  During a power failure, the emergency lighting circuit 150d operates under the control of the control circuit 150c. The control circuit 150c turns off the fourth switch 134 and the fifth switch 135 so that the sense resistor for the emergency lighting circuit 150d has a series combined resistance value of 250e, 250f, and 250g.

  By this control, at the time of emergency lighting using the secondary battery 140 charged in normal use as a power source, it is possible to save energy by reducing current compared to normal use.

  At the time of this emergency lighting, the control circuit 150c controls the control circuit 150c so that the first switch 131 is turned on and the second switch 132 is turned off so that only the second light emitting member 190 is lit. To do.

  In the circuit configuration in which power supply to the service ballast 830 is cut off when the wall switch 911 is turned off as in the circuit shown in FIG. 2, when the wall switch 911 is turned off, the human sensor 121, brightness The sensor 119 cannot be used together. However, as in the present embodiment, the signal detected by the brightness sensor 119 and the human sensor 121 is controlled if the signal of the wall switch 911 is input to the control circuit 150c as a signal for turning off and is turned off. By inputting the signal to the circuit 150c, lighting, dimming, and extinguishing of the first light emitting member 180 and the second light emitting member 190 can be controlled.

  FIG. 5 is a diagram showing lighting variations of the lighting fixture 100b in the present embodiment. FIG. 6 is a diagram illustrating a control flow of lighting variations of the lighting fixture 100b in the present embodiment.

  FIG. 5 is a lighting variation in the luminaire 100b when it is particularly important to ensure the brightness as a nightlight. In FIG. 5, items related to lighting of the first light emitting member 180 and the second light emitting member 190 are displayed in a matrix form, and an operation pattern is shown. FIG. 6 shows a control flow of the control circuit 150c during normal use. The control flow corresponding to 1-8 is shown.

  An example of a lighting variation (operation pattern) of the lighting fixture 100c will be described with reference to FIGS.

  In the lighting fixture 100b of the present embodiment, since the function as a nightlight is to be utilized as much as possible, the priority as the state of each component is as follows: normal power supply 910 presence / absence> human sensor 121> brightness sensor 119> wall switch 911 It is preferable to do.

  The pattern No. in FIG. 1-4, the brightness sensor 119 ensures the brightness regardless of whether the wall switch 911 is turned on or off (S115 or S116 in FIG. 6) during normal use (turned on in S110 in FIG. 6). Even if it is (light and dark in S114 of FIG. 6), when a person is detected (present in S112 of FIG. 6), the second light-emitting member 190 serving as a night-light can always be turned on ( S119 to S122 in FIG.

  Further, the pattern No. in FIG. As shown in 9-18, at the time of a power failure, the 2nd light emission member 190 always lights up, and it is made to evacuate smoothly at the time of an emergency.

  Although not shown in FIG. 5, as a lighting variation of the night light of the lighting apparatus 100c, even if the brightness sensor 119 secures the brightness, the first light emitting member 180 is kept turned on in a dimmed state without being turned off. An operation pattern to be considered is also conceivable. The dimming state is a state in which the brightness is controlled to be equal to or lower than a predetermined brightness.

  As for the second light emitting member, if the brightness at the time of emergency lighting is the brightness that meets the standard, the brightness as the night light during normal use should be the same as the normal lighting of the first light emitting member 180. It is possible to set whether the brightness is the same as that during emergency lighting.

  There are many more combinations when the state of the common power source 910, the human sensor 121, the brightness sensor 119, and the wall switch 911 and the lighting state of the first light emitting member 180 and the second light emitting member 190 are simply combined. The substantial combination is shown in No. 5 of FIG. As shown in 1-18.

  For example, pattern No. In the event of a power outage in the event of an emergency, such as 17 and 18, if there are people and the surroundings are dark, the first light emitting member 180 is also turned on to ensure the prescribed brightness. It is possible to illuminate not only your feet but also the entire landing, and you can expect the effect of evacuating more smoothly.

  The pattern No. in FIG. As shown in FIGS. 17 and 18, in order to turn on the first light emitting member 180 and the second light emitting member 190 in an emergency, the control circuit 150c turns off both the first switch 131 and the second switch 132. It may be controlled to. However, in this case, since the first switch 131 and the second switch 132 are turned on by the secondary battery 140, the capacity of the secondary battery 140 needs to be increased.

  As described above, according to the lighting fixture 100c according to the present embodiment, the light emitting members (the first light emitting member 180 and the second light emitting member 190) are dimmed regardless of whether the wall switch is on or off during normal use. be able to. In addition, energy saving effect can be expected by making dimming possible during normal use.

Embodiment 3 FIG.
In the present embodiment, even in an emergency, the first light emitting member 180 and the second light emitting member 190 can be turned on, and the first light emitting member 180 and the second light emitting member 190 are individually provided. A lighting apparatus 100c having a circuit configuration that enables lighting control will be described.

  FIG. 7 is a circuit diagram showing lighting fixture 100c according to the present embodiment. FIG. 7 is obtained by further adding a configuration to the circuit diagram of FIG. 4 described in the second embodiment. 7, components having the same functions as those in FIG. 4 are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIG. 7, the lighting fixture 100c includes a second emergency lighting circuit 150e, a sense resistor 250h, a sixth switch 136, a ninth switch 139, and a tenth switch 136a.

  When the normal power supply 910 is cut off and a power failure occurs, the switching power supply 112 stops. The control circuit 150c is supplied with power from the secondary battery 140, and the control circuit 150c operates the emergency lighting circuit 150d and the second emergency lighting circuit 150g.

  The sense resistors 250f and 250g, the sense resistor 250e for the emergency lighting circuit 150d, and the sense resistor 250h for the second emergency lighting circuit 150e are connected in series.

  The current flowing through the circuit is larger during normal use than during a power failure. This is because the current for turning on the light source is larger during normal use than during blackout. Therefore, the sense resistor is arranged so that the resistance value of the circuit during normal use (the circuit of the switching power supply 112) is smaller than the resistance value of the circuit during power outage (the circuit of the emergency lighting circuit 150d).

  Specifically, as shown in FIG. 7, the sense resistors are connected in the order of sense resistors 250e, 250f, and 250g. The switching power supply 112 detects the voltage on the upper side of the sense resistor 250f (9th switch 139 side), and the emergency lighting circuit 150d detects the voltage on the upper side of the sense resistor 250e (9th switch 139 side).

  The control circuit 150c turns on and off the fourth switch 134 to obtain the sense resistance value of the circuit of the switching power supply 112 that operates in normal operation and the sense resistance value of the circuit for the second emergency lighting circuit 150e that operates in emergency. It can be changed to change the brightness during normal use and emergency. For example, during normal use, the control circuit 150c turns on the fourth switch 134 to lower the resistance value of the circuit, and during a power failure, the control circuit 150c turns off the fourth switch 134 to increase the circuit resistance value. To do.

  As described above, the sense resistors are connected in the order of the second emergency lighting circuit 150e sense resistor 250h, the emergency lighting circuit 150d sense resistor 250e, and the common and emergency common sense resistors 250f and 250g.

  In normal use, the control circuit 150c controls to turn on the fourth switch 134 and turns on / off the fifth switch 135, so that the sense resistor for the switching power supply 112 is only the sense resistor 250g or the sense resistor 250f + sense. It operates with a resistance of 250 g.

  The second emergency lighting circuit 150e is a circuit for lighting both the first light emitting member 180 and the second light emitting member 190 with different brightness. The sense resistor 250h, the sense resistor 250e, the sense resistor 250f, and the sense resistor 250g. And the current value determined by the series combined resistance of the four sense resistors.

  In the event of a power failure, the control circuit 150c turns off the fourth switch 134 so that the sense resistance for the emergency lighting circuit 150d has a series combined resistance value of 250e, 250f, and 250g. Similarly, at the time of a power failure, the second emergency lighting circuit 150e senses with a combined resistance of the sense resistors 250h, 250e, 250f, and 250g.

  The current sensed by the second emergency lighting circuit 150 e flows to the sense resistor via the ninth switch 139. In this way, an emergency lighting state is achieved in which the current flowing in the emergency is smaller than that in normal use, and the current flowing in the first light emitting member 180 is less than the current flowing in the second light emitting member 190. can do.

  In this emergency lighting, both the first switch 131 and the second switch 132 are controlled by the control circuit 150c so that both the first light emitting member 180 and the second light emitting member 190 are turned on.

  As described above, according to the circuit of the lighting fixture 100c according to the present embodiment, for example, the second light emitting member 190 is turned on and the first light emitting member 180 is blinked with one circuit. The first switch 131 can be controlled by the control circuit 150c.

  Furthermore, the variation (lighting variation) of the operation | movement at the time of emergency lighting of the lighting fixture 100d is demonstrated. The second light emitting member 190 is used as a light source for the purpose of ensuring the brightness of the feet when the surroundings are dark. Further, the first light emitting member 180 is intended to clarify the location of the evacuation route and the stairs, or to make it easily visible. As a method of making the evacuation route and the location of the stairs more noticeable, it is effective to blink the first light emitting member 180 that is a light source.

  FIG. 8 is a diagram illustrating combinations of lighting states of the first light emitting member 180 and the second light emitting member 190 in an emergency of the lighting fixture 100d according to the present embodiment. FIG. 9 is a flowchart of lighting state control of the first light emitting member 180 and the second light emitting member 190 in an emergency of the lighting fixture 100d according to the present embodiment. FIG. 10 is a flowchart of lighting state control of the first light emitting member 180 and the second light emitting member 190 in the emergency of the lighting fixture 100d according to the present embodiment.

  In the present embodiment, an element in which the first light emitting member 180 blinks at the time of emergency lighting in the lighting fixture 100c is added. As shown in FIG. 8, in an emergency, the second light emitting member 190 functions as an emergency light, and thus is in an emergency lighting state. Therefore, the four combination patterns of FIG. 8 can be considered in combination with the lighting, blinking, dimming, and extinguishing states of the first light emitting member 180.

  The operation pattern 15 in FIG. 9 will be described as an example with reference to FIGS. When the power failure is detected, the control circuit 150c causes the first light emitting member 180 to blink in S212 and causes the second light emitting member 190 to be lit in an emergency. In S210, when the control circuit 150c determines that the lighting time has exceeded the specified emergency lighting time (YES in S210), the first light emitting member 180 is turned off and the second light emitting member 190 is continuously turned on ( S211).

  Here, the specified emergency lighting time is a time specified by law as an emergency lighting time as an emergency light.

  As shown in FIG. 9, the second light emitting member 190 is not turned off at least within a specified emergency lighting time and is in a lighting state (emergency lighting state). The first light emitting member 180 is turned on, dimmed, or blinked. When it is desired to reduce the battery capacity, the first light emitting member 180 is dimmed (set to be darker than the emergency lighting state). Thereby, the location of the stairs where the lighting fixture 100c is installed can be clarified and can be easily noticeable.

  In the luminaire 100c, the second light emitting member 190 is lit with a specified brightness and has a function as an emergency light. However, the first light emitting member 180 has its original function when flashing or dimming. Since it is not recognized as a light source for emergency lighting, an auxiliary operation is performed. The operation time (30 minutes or 60 minutes) is defined by law for emergency lighting, and the operation time (20 minutes or 60 minutes) is defined for guide lights. The brightness at the time of emergency lighting can be slightly reduced for the purpose of extending the lighting time of the second light emitting member 190 for a time longer than the predetermined time.

  Lighting variations such as extending the lighting time of the second light emitting member 190 by turning on or blinking the first light emitting member 180, turning on (dimming) the brightness, or turning it off. Can be considered.

  Here, consider the priority of operation considering the role of each light emitting member as an emergency lighting state. When the first light emitting member 180 is caused to function as “light for the purpose of notifying”, the operation priority order is “lit> blink> dimming> extinguish”. Further, when the second light-emitting member is “a night light for illuminating the feet and the original light for emergency lighting”, the priority of operation is “lighting> light control> flashing> (not extinguishing)”. .

  When these operation patterns are combined with the operation time of emergency lighting, there are 256 possible combinations in simple calculation. However, as for substantial combinations, 30 patterns shown in FIG.

  In any of the patterns 1 to 30 shown in FIG. 9, the second light emitting member 190 is lit in an emergency lighting within a specified time, and ensures the brightness of the feet.

  However, for example, when the first light-emitting member 180 is lit in a dimming state within a specified time for emergency lighting, there is no operation that makes the light blinking conversely after the time elapses, and the dimming state is changed. The transition is whether to continue or turn off the light for the purpose of extending the lighting time of the second light emitting member 190.

  When changing the brightness between the first light-emitting member 180 and the second light-emitting member 190, two emergency lighting circuits are required, which complicates the circuit. However, with fine control, the visibility during evacuation is improved. Expected to improve and extend lighting time. An example of this case is shown below.

  For example, an emergency lighting operation pattern 14 in FIG. 9 will be described as an example. When the power failure is detected, the control circuit 150c causes the first light emitting member 180 to blink in S212 and causes the second light emitting member 190 to be lit in an emergency. In S210, when the control circuit 150c determines that the lighting time has exceeded the specified emergency lighting time (YES in S210), the first light emitting member 180 is dimmed and the second light emitting member 190 is lighted in an emergency (S216). ).

  As described above, in the operation pattern 14, when an emergency power failure occurs, the first light emitting member 180 blinks for the purpose of conspicuously locating the stair evacuation route. On the other hand, the second light emitting member 190 is lit up with brightness necessary for emergency evacuation. After the emergency lighting time has been operated in this way until the specified time, if the specified time is exceeded, the first light emitting member stops blinking and lights in a dimming state, and the second light emitting member is necessary for evacuation Continues emergency lighting at a high brightness.

  In some cases, when the time further elapses, both the lighting patterns of the two light emitting members can be changed to the dimming state as indicated by 17 to extend the lighting time.

  A lighting pattern as shown in FIG. 9 can be realized by combining the contents as described above. Since the operation is the same as the content except for which mode it will be, detailed description will be omitted. By combining with lighting patterns for regular use, an optimal emergency lighting fixture that can be used as a nightlight can be realized.

Embodiment 4 FIG.
FIG. 12 is a circuit diagram of a lighting fixture 100d according to the fourth embodiment. FIG. 13 is a diagram illustrating a relationship among the switches, the light emitting members, and the state of the secondary battery 140 of the lighting fixture 100d according to the present embodiment.

  The lighting fixture 100d according to Embodiment 4 shares a constant current circuit that flows through the first light emitting member 180, the second light emitting member 190, and the secondary battery 140. In FIG. 12, the same components as those in FIG. 3 of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  In the lighting fixture 100d, the charging circuit 150a is omitted in order to share a constant current circuit that flows through the first light emitting member 180, the second light emitting member 190, and the secondary battery 140. The current detection sense resistor 250 f is disposed under the secondary battery 4. In the lighting fixture 100d, the third switch 133 used at the time of extinguishing is deleted and short-circuited.

  As illustrated in FIG. 12, the lighting fixture 100 d includes a seventh switch 137 and an eighth switch 138. The control circuit 150c controls the seventh switch 137 so that it is turned off during normal lighting and turned on during emergency lighting. The control circuit 150c controls the eighth switch 138 so that it is turned on during normal lighting and turned off during emergency lighting.

  As shown in FIGS. 12 and 13, in normal use, when the first light emitting member 180 is turned on and the second light emitting member 190 is turned off, the first switch 131 is turned off and the second switch 132 is turned on. Is turned on, the seventh switch 137 is turned off, and the eighth switch 138 is turned on. As a result, the output of the switching power supply 112 forms a closed loop that returns to the switching power supply 112 via the first light emitting member 180, the second switch 132, the eighth switch 138, and the secondary battery 140.

  That is, the circuit for lighting the first light emitting member 180 and the circuit for charging the secondary battery 140 are combined. A sense resistor 250f is disposed under the secondary battery 140, and the switching power supply 112 operates to pass a constant current through the circuit. The constant current feedback is a voltage generated in the sense resistor 250f.

  When the light is turned off by the wall switch 911 or the like, the first light emitting member 180 is turned off, and the second light emitting member 190 is a night light. Then, the secondary battery 140 is charged. In this case, the first switch 131 is turned on, the second switch 132 is turned off, the seventh switch 137 is turned off, and the eighth switch 138 is turned on. As a result, the output of the switching power supply 112 forms a closed loop that returns to the switching power supply 112 via the first switch 131, the second light emitting member 190, the eighth switch 138, and the secondary battery 140. The first switch 131 and the second switch 132 may both be turned on so that current flows only through the secondary battery 140.

  When the switching power supply 112 stops during a power failure, power is supplied from the secondary battery 140 to the emergency lighting circuit 150d. The first light emitting member 180 is turned off, and the second light emitting member 190 is lit up. In this case, the first switch 131 is turned on, the second switch 132 is turned off, the seventh switch 137 is turned on, and the eighth switch 138 is turned off. Thus, the output of the emergency lighting circuit 150d forms a loop that returns to the secondary battery 140 via the first switch 131, the second light emitting member 190, the seventh switch 137, and the sense resistor 250e. The constant current feedback of the emergency lighting circuit 150d is the voltage of the sense resistor 250e.

  In addition, when the first light emitting member 180 is turned on and the second light emitting member 190 is turned on at the time of a power failure, the first switch 131 is turned off, the second switch 132 is turned off, and the seventh switch 137 is turned on. Is turned on, and the eighth switch 138 is turned off. As a result, the output of the emergency lighting circuit 150d forms a loop that returns to the secondary battery 140 via the first light emitting member 180, the second light emitting member 190, the seventh switch 137, and the sense resistor 250e. The constant current feedback of the emergency lighting circuit 150d is the voltage of the sense resistor 250e.

  As described above, according to lighting apparatus 100d according to the present embodiment, secondary battery 140 is charged during normal use, and the charging current turns on first light emitting member 180 (or second light emitting member 190). The constant current circuit is the same as the current to be transmitted. Therefore, by sharing the constant current circuit for lighting the first light emitting member 180 (or the second light emitting member 190) and the constant current circuit for charging the secondary battery 140, the circuit is simplified and the number of parts is reduced. Can be planned.
