The guide light device 100 includes a power supply unit 160, a battery 170, a main light source module 180, and harnesses 191 and 192 inside the main body 110.
The main light source module 180 (main light source circuit) illuminates the evacuation guidance figure drawn on the panel unit 120 from the inside. The main light source module 180 is disposed downward in the upper part inside the main body 110. The main light source module 180 includes, for example, a substrate 181 and a light source 182. The light source 182 (main light source) is a light source that emits light by electric energy, such as an LED, a fluorescent lamp, or a cold cathode ray lamp. The light source 182 is mounted on the substrate 181. The substrate 181 is, for example, a printed wiring board. A circuit that supplies power supplied from the power supply unit 160 to the light source 182 is formed on the substrate 181 with printed wiring, components mounted on the substrate 181, and the like.

The induction panel 121 is made of a material such as a resin that transmits light. The guide panel 121 includes, for example, a flat plate part 122 and a light guide part 127 (light guide plate). The flat plate portion 122 is a portion exposed to the outside of the guide lamp device 100, and has a square plate shape, for example. On the front side surface of the flat plate part 122, an evacuation guide figure 124 (display part) is drawn largely in the center. In addition, a translucent portion 123 is provided around the evacuation guide figure 124. The translucent part 123 is transparent, does not diffuse light, and transmits as it is. The light guide 127 is located on the back side of the evacuation guide figure 124. The light guide 127 guides the light emitted from the light source 182 of the main light source module 180 to illuminate the evacuation guide pattern 124. The evacuation guide pattern 124 is illuminated from the back side by the light guided by the light guide unit 127 and emits light substantially uniformly. The light guide unit 127 may be a separate component from the flat plate unit 122.
The peripheral light source module 130 is disposed on the back side of the light transmitting portion 123. The peripheral light source module 130 has a light source. The outer peripheral light source module 130 receives power from the power supply unit 160 and turns on the light source. The light emitted from the light source of the peripheral light source module 130 is radiated to the outside of the guide lamp device 100 through the light transmitting portion 123.
The harness 194 physically and electrically connects the plurality of outer peripheral light source modules 130.
The harness 193 is connected to the power supply unit 160. The harness 193 physically and electrically connects the power supply unit 160 and the outer peripheral light source module 130.

FIG. 4 is a front view and a cross-sectional view showing the structure of the guide panel 121 in this embodiment.
The flat plate part 122 includes, for example, a groove part 125 and an engaging part 126. The groove part 125 is provided on the back side of the translucent part 123. The groove part 125 is a space for accommodating the light source of the outer peripheral light source module 130. The engaging part 126 is provided on both sides of the groove part 125. The engaging portion 126 engages with the outer peripheral light source module 130 and positions the outer peripheral light source module 130.
The light guide unit 127 includes, for example, an incident unit 128 and a diffuse reflection unit 129. The incident portion 128 is positioned in front of the light source 182 of the main light source module 180 when the panel unit 120 is attached to the main body 110. The incident unit 128 takes light emitted from the light source 182 into the light guide unit 127. The diffuse reflection part 129 diffuses and reflects the light emitted from the light source 182 and taken in from the incident part 128 to irradiate the evacuation guide figure 124.

FIG. 5 is a front view and a cross-sectional view showing the structure of the outer peripheral light source module 130 in this embodiment.
The peripheral light source module 130 (LED module) includes, for example, a substrate 131, a light source 132, and a connector 133. The light source 132 is a point light source or a light source having a relatively small area of a light emitting portion, such as an LED package. The light source 132 emits yellow or orange light. The main wavelength of light emitted from the light source 132 is, for example, 550 nm to 620 nm, and preferably 570 nm to 610 nm. This is because light in this wavelength band is excellent in visibility even in a state where smoke is filled. The light source 132 emits light having high directivity. The half beam angle of the light emitted from the light source 132 is, for example, 30 degrees or less, and desirably 5 degrees or less. “Half beam angle” is one of the indexes representing the light distribution characteristics of a light source having a rotationally symmetric light distribution. It is the angle formed by the direction in which light of 1 intensity is emitted. The light source 132 is mounted on the substrate 131.
The connector 133 engages with the harnesses 193 and 194 to make a physical and electrical connection. The connector 133 is mounted on the substrate 131.
The substrate 131 is, for example, a printed wiring board. The board 131 is supplied with power supplied from the power supply unit 160 to the light source 132 via harnesses 193 and 194 connected to one connector 133 by printed wiring, components mounted on the board 131, and the like. A circuit to be supplied to the other peripheral light source module 130 through a harness 194 connected to the other connector 133 is formed.

  The light source 132 is arranged around the evacuation guide figure 124 by arranging the outer peripheral light source module 130 to be engaged with the engaging portion 126 of the guide panel 121. The light source 132 emits light in a direction centered on a direction substantially perpendicular to the flat plate portion 122 of the guide panel 121. The plurality of light sources 132 emit light in substantially the same direction. The light emitted from the light source 132 passes through the translucent portion 123 and is emitted as it is in a direction centered on a direction substantially perpendicular to the flat plate portion 122.

FIG. 6 is a block diagram showing the guide light system 800 and the guide light device 100 in this embodiment.
The guide light system 800 includes, for example, a guide light device 100 and a smoke sensing device 810. The smoke detection device 810 (smoke detector) is installed near the guide light device 100. The smoke detection device 810 detects smoke and outputs a smoke detection signal. The smoke detection signal output from the smoke detection device 810 may represent a value of smoke density detected by the smoke detection device 810, or the smoke concentration detected by the smoke detection device 810 exceeds a predetermined threshold. It may represent whether or not. The smoke sensing device 810 may be formed integrally with the guide light device 100.
The guide light device 100 operates by receiving power from a power source AC such as a commercial power source in normal times. The guide light device 100 includes, for example, a power supply unit 160, a battery 170, a main light source circuit 185, and a sub light source circuit 135. The main light source circuit 185 is a circuit formed in the main light source module 180 described above. The sub light source circuit 135 is a circuit in which circuits formed in the plurality of outer peripheral light source modules 130 described above are connected by a harness 194.
The power supply unit 160 includes, for example, a power failure detection circuit 161, a power supply circuit 162, a control circuit 163, a main lighting circuit 164, and a sub lighting circuit 165.
The power failure detection circuit 161 detects the presence or absence of power supply from the power source AC, and determines whether it is normal or during a power failure. The power failure detection circuit 161 outputs a power failure detection signal representing the determined result.
The power supply circuit 162 (power supply voltage switching circuit) receives the power failure detection signal output from the power failure detection circuit 161. Based on the input power failure detection signal, the power supply circuit 162 supplies the power supplied from the power supply AC to the power for charging the battery 170, the control circuit 163, the main lighting circuit 164, and the sub-lighting circuit 165 in normal operation. Is converted into power for operating. Further, the power supply circuit 162 operates the control circuit 163, the main lighting circuit 164, and the sub-lighting circuit 165 with the power obtained by discharging the battery 170 in the event of a power failure based on the input power failure detection signal. Convert to power for.
The control circuit 163 (lighting control unit) is, for example, a microcomputer. The control circuit 163 operates with electric power supplied from the power supply circuit 162. The control circuit 163 receives the power failure detection signal output from the power failure detection circuit 161 and the smoke detection signal output from the smoke sensing device 810. The control circuit 163 generates a main control signal for controlling the operation of the main lighting circuit 164 and a sub control signal for controlling the operation of the sub lighting circuit 165 based on the input power failure detection signal and the smoke detection signal. . The control circuit 163 outputs the generated main control signal and sub control signal.
The main lighting circuit 164 (guide light main light source lighting circuit) receives the main control signal output from the control circuit 163. The main lighting circuit 164 converts the power supplied from the power supply circuit 162 into the power supplied to the main light source circuit 185 based on the instruction represented by the input main control signal.
The sub lighting circuit 165 (outer peripheral LED lighting circuit) receives the sub control signal output from the control circuit 163. The sub lighting circuit 165 converts the power supplied from the power supply circuit 162 into power supplied to the sub light source circuit 135 based on the instruction represented by the input sub control signal.

For example, the control circuit 163 controls the main lighting circuit 164 and the sub-lighting circuit 165 as follows.
When the power failure detection circuit 161 does not detect a power failure and the smoke sensing device 810 does not sense smoke (including the case where the smoke concentration sensed by the smoke sensing device 810 is lower than the threshold; the same applies hereinafter). Operates the main lighting circuit 164 to turn on the light source 182 of the main light source module 180 with normal brightness. As a result, the evacuation guidance graphic 124 emits surface light. The control circuit 163 turns off the light source 132 of the outer peripheral light source module 130 without operating the auxiliary lighting circuit 165.
When the power failure detection circuit 161 detects a power failure and the smoke sensing device 810 does not sense smoke, the control circuit 163 activates the main lighting circuit 164 to set the light source 182 of the main light source module 180 at the brightness at the time of the power failure. Light up. As a result, the evacuation guidance graphic 124 emits surface light. The control circuit 163 turns off the light source 132 of the outer peripheral light source module 130 without operating the auxiliary lighting circuit 165.
When the power failure detection circuit 161 does not detect a power failure and the smoke sensing device 810 senses smoke (or when the smoke concentration sensed by the smoke sensing device 810 is higher than a threshold value, the same applies hereinafter). Operates the main lighting circuit 164 to light the light source 182 of the main light source module 180 brighter than usual. As a result, the evacuation guidance graphic 124 emits surface light. In addition, the control circuit 163 operates the auxiliary lighting circuit 165 to turn on the light source 132 of the outer peripheral light source module 130.
When the power failure detection circuit 161 detects a power failure and the smoke sensing device 810 senses smoke, the control circuit 163 activates the main lighting circuit 164 to turn on the light source 182 of the main light source module 180 with the brightness at the time of the power failure. Light up. In addition, the control circuit 163 operates the auxiliary lighting circuit 165 to turn on the light source 132 of the outer peripheral light source module 130.
That is, the light source 132 of the peripheral light source module 130 is turned on when the smoke detection device 810 detects smoke.

FIG. 7 is a diagram showing the apparent luminance of the evacuation guide pattern 124 around the guide lamp device 100 according to this embodiment.
The higher the shading density, the higher the apparent luminance.
In the state where the smoke is filled indoors, the light hits the smoke and is diffusely reflected, so that the light reaching from the evacuation guide pattern 124 attenuates as the distance from the guide light device 100 increases.
Since the apparent luminance of the evacuation guide graphic 124 decreases as the distance from the guide light device 100 increases, it may be difficult to visually recognize the evacuation guide graphic 124 at a position away from the guide light device 100.

FIG. 8 is a diagram showing the apparent luminance of the light source 132 that can be seen through the translucent portion 123 around the guide lamp device 100 in this embodiment.
The higher the shading density, the higher the apparent luminance.
Since the light source 132 is a point light source or a light source close thereto, the luminance is very high as compared with the evacuation guide figure 124. For this reason, the light source 132 can be seen from a distance even when the interior is filled with smoke.
Furthermore, light having a strong directivity emitted from the light source 132 is irregularly reflected on the smoke, so that light streaks appear to appear in the air. For this reason, even if it sees from directions other than the direction where the light source 132 radiates | emits light, presence of the guide light apparatus 100 can be recognized. By following the streaks of light floating in the air, the position of the guide light device 100 can be recognized, so that evacuation can be performed safely and quickly.

  In addition, when the indoor space is not filled with smoke, when the light source 132 is turned on, the person who is in a position where the light emitted from the light source 132 can be directly seen is too dazzled and the evacuation guide figure 124 becomes difficult to see. For this reason, when the smoke sensing device 810 does not sense smoke, the light source 132 is turned off.

As described above, when the smoke detecting device 810 detects smoke, the evacuation guide figure 124 becomes difficult to visually recognize. Therefore, by turning on the light source 132, the position of the guide light device 100 can be recognized, and evacuation can be performed safely and quickly. It can be so. In addition, when the smoke detection device 810 does not detect smoke, the light guide 132 is turned off to make the evacuation guide figure 124 easier to visually recognize.
Further, since the directivity of the light source 132 is strong, the light irregularly reflected by the smoke looks like a streak and the position of the guide light device 100 can be easily recognized. Since the plurality of light sources 132 are arranged around the evacuation guide figure 124 and the directions of light emission are substantially the same, the streaks of light appear thick and the position of the guide light device 100 can be easily recognized.
In addition, since the light emitted from the light source 132 is yellow or orange, visibility is high even if the smoke is full.

When the smoke detection device 810 detects smoke, the control circuit 163 may be configured to blink the light source 132 of the outer peripheral light source module 130. For example, the control circuit 163 may be configured to repeatedly operate and stop the sub-lighting circuit 165, or a flashing control circuit is provided in the sub-lighting circuit 165, and the control circuit 163 instructs the flashing operation. The sub-control signal may be generated, and the blinking control circuit of the sub-lighting circuit 165 may repeatedly supply power to the sub-light source circuit 135 and stop according to the instruction by the sub-control signal.
Thereby, it becomes easier to recognize the position of the guide light device 100. Moreover, since the average power consumption in the outer periphery light source module 130 can be suppressed by blinking the light source 132, the lighting time of the guide lamp apparatus 100 at the time of a power failure can be lengthened.

In addition, when the smoke detection device 810 detects smoke, the control circuit 163 may be configured to light the light source 182 of the main light source module 180 more darkly than when the smoke detection device 810 does not detect smoke. When the smoke sensing device 810 senses smoke, the light source 132 of the outer light source module 130 is turned on (or flashes), so that the position of the guide light device 100 can be recognized even if the brightness of the evacuation guide figure 124 is lowered. Can do. Thereby, since the power consumption in the main light source module 180 can be suppressed, the lighting time of the guide lamp apparatus 100 at the time of a power failure can be lengthened.
Alternatively, when the smoke sensing device 810 senses smoke and the power failure detection circuit 161 detects a power failure, the control circuit 163 blinks or turns off the light source 182 of the main light source module 180. May be. Then, the power consumption in the main light source module 180 can be further suppressed, so that the lighting time of the guide lamp device 100 during a power failure can be further increased.

Moreover, the streak of light irregularly reflected in the smoke becomes thicker and the position of the guide light device 100 can be easily recognized.

  Note that not only the light sources 132 arranged on the left and right sides of the evacuation guidance figure 124 but also the light sources 132 arranged on the upper side and the lower side of the evacuation guidance figure 124 so that the emitted light is directed obliquely outward.

FIG. 12 is a block diagram showing the guide light system 800 and the guide light device 100 in this embodiment.
The guide light system 800 further includes a temperature sensing device 820 (heat detector) in addition to the configuration described in the first embodiment. The temperature sensing device 820 is installed near the guide light device 100. The temperature sensing device 820 may be formed integrally with the guide lamp device 100. The temperature sensing device 820 senses the temperature around the guide lamp device 100 and outputs a temperature sensing signal. The temperature sensing signal output from the temperature sensing device 820 may represent a temperature value sensed by the temperature sensing device 820, and whether or not the temperature sensed by the temperature sensing device 820 exceeds a predetermined threshold. It may be a representation.

  The control circuit 163 inputs the power failure detection signal output from the power failure detection circuit 161, the smoke detection signal output from the smoke detection device 810, and the temperature detection signal output from the temperature detection device 820. The control circuit 163 controls the operation of the main lighting circuit 164 and the sub-control that controls the operation of the sub-lighting circuit 165 based on the input power failure detection signal, smoke detection signal, and temperature detection signal. Signal.

For example, the control circuit 163 controls the main lighting circuit 164 and the sub-lighting circuit 165 as follows.
When the temperature sensed by the temperature sensing device 820 is lower than the threshold value, the control circuit 163 controls the main lighting circuit 164 and the sub lighting circuit 165 in the same manner as described in the first embodiment, for example.
When the temperature sensed by the temperature sensing device 820 is higher than the threshold value, the control circuit 163 does not operate the main lighting circuit 164 and the sub lighting circuit 165, and turns off the light source 182 of the main light source module 180 and the light source 132 of the peripheral light source module 130. Let

  When the temperature sensed by the temperature sensing device 820 is higher than the threshold value, there is a possibility that a flame is approaching near the guide light device 100. The guide light device 100 turns off the light source 182 and the light source 132 because it is rather dangerous to evacuate in a certain direction of the guide light device 100.

  As described above, when the temperature sensed by the temperature sensing device 820 is higher than the threshold value, the guide light device 100 does not guide evacuation, but evacuates a person in the room according to guidance from another guide light device or the like. Can be evacuated safely and quickly.

  The temperature sensing device 820 may be arranged not near the guide light device 100 but near the emergency exit to which the guide light device 100 guides or in the middle of an evacuation route.

  As described above, the configuration described in each embodiment is an example, and another configuration may be used. For example, the structure which combined the structure demonstrated in different embodiment may be sufficient, and the structure which replaced the structure of the non-essential part with the other structure may be sufficient.
