[0001] The present disclosure relates to lighting systems, and more particularly to lighting systems that remotely control light sources. [Background technology]

[0002] The lighting device described in Patent Document 1 is taken as an example of a conventional lighting device. The lighting device described in Patent Document 1 (hereinafter referred to as the conventional lighting device) includes a lighting means that uses an LED as a light source to illuminate an illumination space, a light sensor that detects the light intensity of the reflected light when light emitted from the lighting means is reflected by an object, and a control processing means that controls the lighting of the lighting means using PWM control.

[0010] Hereinafter, lighting systems according to embodiments of the present disclosure will be described in detail with reference to the drawings. However, the drawings described in the following embodiments are schematic diagrams, and the ratios of the sizes and thicknesses of the components do not necessarily reflect the actual dimensional ratios. Note that the configurations described in the following embodiments are merely examples of the present disclosure. The present disclosure is not limited to the following embodiments, and various modifications are possible depending on the design, etc., as long as the effects of the present disclosure can be achieved.

[0011] (1) Overview The lighting system S1 of this embodiment includes a light source unit 10 that emits illumination light, a power supply unit 11 that supplies power to the light source unit 10, and a control unit 12 that controls the power supply unit 11 to adjust at least one of the light intensity and light color of the illumination light.

[0012] The light source unit 10 is turned on by power supplied from the power supply unit 11 and emits illumination light. For example, the light source unit 10 has one or more LEDs (Light Emitting Diodes). However, the light source unit 10 may have light-emitting elements other than LEDs, such as organic EL (Electro Luminescence) elements or laser diodes. The light source unit 10 has multiple types of LEDs with different light colors, making it possible to change (adjust) the illumination light.

[0013] Based on an external instruction, the control unit 12 controls the power supply unit 11 in accordance with a lighting control pattern that changes at least one of the intensity and color of the illumination light multiple times. The power supply unit 11 operates, for example, to match the power (current) supplied to the light source unit 10 with a target value. The control unit 12 can adjust (dimming, color adjustment) the intensity and color of the illumination light by changing the target value of the power (current). The lighting control pattern includes lighting effects that encourage people within the illumination light's irradiation range to take a predetermined action.

[0014] For example, as shown in Figure 2, assume that dinner is ready and a parent (person H1) in a dining room R1 wants a child (person H2) in a child's room R2 to move out of the room (leave) and come into the dining room R1. In this case, the space that is the illumination range of the illumination light (hereinafter referred to as the illumination range) is the child's room R2, where the lighting system S1 is installed on the ceiling.

[0015] The parent (person H1) operates an operation terminal B1 (described later) to send instructions to the control unit 12 of the lighting system S1. Based on instructions from outside (the operation terminal B1), the control unit 12 controls the power supply unit 11 in accordance with a lighting control pattern including a lighting design that prompts the person H2 (child) who is within the illumination range (child's room R2) of the illumination light to take a predetermined action (leave the room). Here, the lighting design that prompts the child (person H2) to take a predetermined action (leave the room) is, for example, a lighting design that makes the person H2 (child) who is within the illumination range (child's room R2) feel uncomfortable. Note that an uncomfortable lighting design is, for example, a lighting design that makes the person H2 (child) feel uneasy, irritated, or unpleasant, and specifically, a lighting design that increases or decreases the amount of illumination light in a relatively short cycle.

[0016] Thus, the lighting system S1 according to the embodiment is configured as described above, and can cause a person within the illumination range of the illumination light to take a predetermined action.

[0017] (2) Details (2-1) Configuration of the lighting system according to the embodiment An illumination system S1 according to an embodiment (hereinafter abbreviated as illumination system S1) includes a light source unit 10, a power supply unit 11, and a control unit 12 (see FIG. 1).

[0018] The light source unit 10 includes an LED module having, for example, a plurality of LEDs that emit illumination light of warm white (correlated color temperature of 3250K to 2600K) and a plurality of LEDs that emit illumination light of daylight white (correlated color temperature of 5500K to 4600K). However, the light source unit 10 may also include an LED module that emits light of a light color other than warm white and daylight white, for example, light of four colors: red, green, blue, and white.

[0019] The power supply unit 11 has a lighting circuit that lights up the incandescent white LED module of the light source unit 10, a lighting circuit that lights up the daylight white LED module of the light source unit 10, and a control circuit that controls each lighting circuit separately to increase or decrease the current supplied to each LED module.

[0020] Each lighting circuit includes a rectifier that rectifies the AC voltage supplied from the power system PS, a power factor correction circuit that boosts and smooths the pulsating voltage output from the rectifier, and two step-down chopper circuits that step down the DC voltage output from the power factor correction circuit. However, the two lighting circuits may share one rectifier and one power factor correction circuit.

[0021] One of the two step-down chopper circuits in each lighting circuit supplies DC current to a plurality of LEDs that emit incandescent light, and the other supplies DC current to a plurality of LEDs that emit daylight white light. The control circuit controls each lighting circuit so that the output current of these two step-down chopper circuits matches a target value. As a result, the control circuit can individually adjust (dimming, color adjustment) the light intensity and light color (correlated color temperature) of the illumination light emitted from the light source unit 10. The target value of the output current in each lighting circuit is determined by the dimming control pattern.

[0022] The control unit 12 has a microcontroller and a non-volatile memory that stores dimming control patterns and the like. The control unit 12 is configured to execute various processes, which will be described later, by causing the microcontroller to execute a program. The control unit 12 also has a function of communicating with the operation terminal B1. The control unit 12 is electrically and communicably connected to the operation terminal B1 via a signal line L1 (see FIG. 2). However, the control unit 12 may also communicate with the operation terminal B1 via power line carrier communication using a power supply path from the power system PS as a communication medium, or wireless communication using radio waves as a communication medium, such as Wi-Fi (registered trademark) or Bluetooth (registered trademark).

[0023] The operation terminal B1 is configured to receive an operation input and transmit a command (instruction) corresponding to the received operation input to the control unit 12 of the lighting system S1. The operation terminal B1 may be a portable communication terminal such as a smartphone or a tablet.

[0024] (2-2) Operation of the lighting system according to the embodiment Next, the operation of the lighting system S1 will be described. In the following explanation of the operation, it is assumed that an instruction is given to the lighting system S1 installed in a child's room R2 of a house from an operation terminal B1 installed in a dining room R1 of the house (see FIG. 2). However, the space in which the lighting system S1 is installed does not have to be separated from other spaces (rooms) by a wall. For example, the living room and dining room may be a continuous space without being separated by a wall, and the lighting system S1 may be installed in the living room and the operation terminal B1 may be installed in the dining room. Furthermore, the lighting system S1 may be installed not only in homes but also in public facilities such as schools, office buildings, hospitals, commercial facilities, etc.

[0025] The lighting system S1 is configured as, for example, a ceiling light for a home. However, the lighting system S1 is not limited to a ceiling light and may be a downlight embedded in the ceiling. Furthermore, the light source unit 10, power supply unit 11, and control unit 12 do not have to be housed in the same housing. Note that the dining room R1 and the children's room R2 are separated by a wall W1, and therefore the children's room R2 is within the range of illumination light from the light source unit 10.

[0026] Now, let us assume that dinner is ready and a parent (person H1) in the dining room R1 wants their child (person H2) in the child's room R2 to move out of the child's room R2 (leave) and come into the dining room R1.

[0027] The parent (person H1) operates the operation terminal B1 to send a command to the control unit 12 of the lighting system S1. Based on an instruction (command) from outside (the operation terminal B1), the control unit 12 controls the power supply unit 11 according to a lighting control pattern including a lighting effect that prompts the person H2 (child) who is within the illumination range (child's room R2) of the illumination light to take a predetermined action (to leave the room). Here, the lighting effect that prompts the child (person H2) to take a predetermined action (to leave the room) is, for example, a lighting effect that prompts the person H2 (child) who is within the illumination range (child's room R2) to recognize some kind of signal or to feel discomfort. In other words, by making the person H2 recognize some kind of signal or by feeling discomfort, it is possible to provide the child (person H2) with an opportunity (or motivation) to move out of the illumination range (child's room R2).

[0028] The illumination control pattern is composed of a combination of multiple types of sub-illumination control patterns, including a pattern that periodically increases or decreases the amount of illumination light, a pattern that irregularly increases or decreases the amount of illumination light, a pattern that changes the color of illumination light, and a pattern that combines changes in the amount and color of illumination light.

[0029] It is preferable that a lighting control pattern for realizing a lighting effect that makes a certain signal recognizable (hereinafter, sometimes referred to as a lighting control pattern for a signal) includes a sub-lighting control pattern that increases or decreases the amount of light or changes the light color at a relatively long period (e.g., once every few seconds).

[0030] On the other hand, a lighting control pattern for realizing a lighting effect that causes discomfort (hereinafter, sometimes referred to as an discomfort lighting control pattern) preferably includes a sub-lighting control pattern that increases or decreases the light intensity or changes the light color in a relatively short cycle (e.g., several times per second). Alternatively, the discomfort lighting control pattern preferably includes a sub-lighting control pattern that has a larger difference between the maximum and minimum light intensity values ​​or a larger color difference (e.g., difference in correlated color temperature) when changing the light color compared to the signal lighting control pattern. Furthermore, the discomfort lighting control pattern may include a sub-lighting control pattern that changes the light color to one that is not suitable for a normal work environment, such as red, green, or blue.

[0031] Here, instead of executing multiple types of sub-lighting control patterns consecutively, the control unit 12 may control the power supply unit 11 to provide an interval period during which the illumination light is not changed between the previous sub-lighting control pattern and the subsequent sub-lighting control pattern.

[0032] Furthermore, it is preferable that two consecutive sub-lighting control patterns in a lighting control pattern are of different types. However, the same sub-lighting control pattern may be consecutively executed with a different type of sub-lighting control pattern sandwiched between them. By not executing the same type of sub-lighting control pattern consecutively, person H2 (child) can be prevented from becoming accustomed to the stimulation of the lighting effects.

[0033] Alternatively, it is preferable that the lighting control pattern includes a lighting effect in which, of two consecutive sub-lighting control patterns, the later sub-lighting control pattern provides a stronger stimulus to the person than the earlier sub-lighting control pattern. For example, if the degree of discomfort caused by the second and third sub-lighting control patterns is gradually increased compared to the degree of discomfort caused by the first sub-lighting control pattern, it becomes easier to get the child (person H2) to move out of the child's room R2 (the illumination range of the illumination light) more quickly.

[0034] Furthermore, the lighting control pattern preferably includes a sub-lighting control pattern corresponding to a lighting effect that does not cause discomfort, before a sub-lighting control pattern corresponding to a lighting effect that causes discomfort. For example, the lighting control pattern controls the power supply unit 11 according to one or more sub-lighting control patterns corresponding to a signal lighting control pattern, and then controls the power supply unit 11 according to the sub-lighting control pattern corresponding to an discomfort lighting control pattern. In other words, the lighting system S1 first alerts the child (person H2) and then makes the child (person H2) feel uncomfortable, thereby enabling the child (person H2) to move out of the child's room R2 (the illumination range of the illumination light) more quickly.

[0035] However, it is not desirable for person H2 (child) who is within the illumination range to be able to arbitrarily stop the control of power supply unit 11 by control unit 12 according to the lighting control pattern. Therefore, it is preferable for control unit 12 to stop the control of power supply unit 11 according to the lighting control pattern based on an instruction from operation terminal B1. In other words, lighting system S1 causes control unit 12 to stop the control of power supply unit 11 according to the lighting control pattern based on an instruction from outside (operation terminal B1), thereby preventing person H2 (child) who is within the illumination range (child's room R2) from interfering with the lighting control.

[0036] Furthermore, it is preferable that the lighting control pattern has at least the last sub-lighting control pattern that sets the light intensity to zero. That is, after the person H2 (child) moves (exits) out of the illumination range (child's room R2), there is no need to turn on the light source unit 10. Therefore, by setting the light intensity to zero in at least the last sub-lighting control pattern, the lighting system S1 can reduce unnecessary power consumption and achieve energy conservation. Alternatively, if the person H2 (child) is present within the illumination range (child's room R2), the lighting system S1 can more reliably cause the person H2 (child) to move (exit) out of the illumination range (child's room R2) by setting the light intensity to zero.

[0037] Furthermore, when the control unit 12 has set the light intensity to zero based on the sub-lighting control pattern, it is preferable that the control unit 12 controls the power supply unit 11 to maintain the light intensity at zero until an instruction to turn the light on again is received from outside (operation terminal B1). In other words, the lighting system S1 causes the control unit 12 to control the power supply unit 11 to turn the light source unit 10 on again based on an instruction from outside (operation terminal B1), so that it is possible to prevent a person H2 (child) in the illumination range (child's room R2) from arbitrarily turning the light source unit 10 on again and interfering with the lighting control.

[0038] However, when the control unit 12 sets the light intensity to zero based on the sub-lighting control pattern, it is preferable that the control unit 12 stop controlling the power supply unit 11 according to the lighting control pattern if it receives notification of an emergency from outside. For example, since the installation of a residential fire alarm is required by law in homes, when a fire (emergency) occurs and the residential fire alarm goes off, it is preferable that the control unit 12 be notified of the fire from the operation terminal B1. Then, when the control unit 12 receives notification of the fire from the operation terminal B1, it stops controlling the power supply unit 11 according to the lighting control pattern. As a result, a person H2 (child) in the illumination range (child's room R2) can turn on the light source unit 10 by operating the wall switch for the light, for example.

[0039] Alternatively, when an earthquake early warning issued by the Japan Meteorological Agency is received by operation terminal B1 via the Internet, it is desirable for operation terminal B1 to notify control unit 12 of the occurrence of an earthquake. Then, when control unit 12 is notified of the occurrence of an earthquake from operation terminal B1, it stops control of power supply unit 11 according to the lighting control pattern. As a result, person H2 (child) in the illumination range (child's room R2) can turn on light source unit 10 by operating the wall switch for the light, for example. However, emergencies are not limited to fires and earthquakes, and include, for example, heavy rain, river flooding, and landslides.

[0040] (3) Variations Next, several modified examples of the lighting system S1 according to the embodiment will be described. However, the basic configuration of the lighting system S1 of each modified example described below is common to the basic configuration of the lighting system S1 according to the embodiment. Therefore, the same reference numerals will be used to designate components that are common to the basic configuration of the lighting system S1 according to the embodiment, and illustrations and descriptions thereof will be omitted as appropriate. In the following description, "substantially common configuration" means a configuration that is slightly different in shape, size, etc., but has the same function.

[0041] (3-1) Variation 1 The lighting system S1 of the first modification is characterized by including a plurality of light source units 10. For example, the lighting system S1 may include a desk lamp D1 (light source unit, power supply unit, control unit) placed on a table in addition to the light source unit 10 of a ceiling light C1 installed on the ceiling of a child's room R2 (see FIG. 3). However, the plurality of light source units 10 may be provided in a single lighting device. Furthermore, the number of light source units 10 is not limited to two, and may be three or more.

[0042] Here, the lighting system S1 of Modification 1 is configured to perform wireless communication between the control unit 12 of the ceiling light C1, the control unit of the desk lamp D1, and the operation terminal B1 using radio waves as a communication medium. Note that the operation terminal B1 in Modification 1 is, for example, a smartphone on which a lighting control app is installed. The control unit 12 of the ceiling light C1 and the control unit of the desk lamp D1 control the power supply unit 11 in accordance with the lighting control pattern described above, based on instructions transmitted by wireless signals from the operation terminal B1.

[0043] Thus, the lighting system S1 of the first modification includes a plurality of light source units 10, and therefore can move (exit) the person H2 (child) out of the illumination range (child's room R2) more quickly.

[0044] (3-2) Variation 2 The lighting system S1 of the second modification includes a speaker 13 (see FIGS. 4 and 5). The lighting system S1 of the second modification is a disc-shaped ceiling light, and further includes an annular frame 20 and a cover 21 that is placed inside the frame 20 (see FIG. 5).

[0045] The cover 21 is formed in a hemispherical shape from a translucent synthetic resin such as an acrylic resin, etc. The cover 21 is configured to diffuse the light emitted from the light source unit (LED module).

[0046] The frame 20 is made of synthetic resin and has a circular ring shape. The frame 20 has a pair of sound output sections 200 with a plurality of holes formed therein for passing sound output from the speaker 13 (see FIG. 5). The speaker 13 is disposed on the back (top) of the frame 20.

[0047] The control unit 12 controls the speaker 13 to output sound to the illumination range (children's room R2) in accordance with the lighting control pattern. Note that the sound output from the speaker 13 includes, for example, music, environmental sounds, and the like.

[0048] Therefore, the lighting system S1 of variant example 2 can make a person H2 (child) who is within the illumination range of the lighting light (child's room R2) take a predetermined action more quickly by outputting sound from the speaker 13 according to the lighting control pattern.

[0049] (3-3) Variation 3 The lighting system S1 of the third modification includes a fan 14 (see FIGS. 6 and 7). The fan 14 has a main body 140 attached to the ceiling and four blades 141 rotatably provided at the bottom of the main body 140 (see FIG. 7). A motor for rotating the blades 141 is built into the main body 140.

[0050] Four LED lamps 22 are attached to the bottom of the main body 140. Each LED lamp 22 is equipped with a light source unit 10. The power supply unit 11 and control unit 12 are housed inside the main body 140. However, each LED lamp 22 may be provided with one power supply unit 11 and one control unit 12. The control unit 12 controls the blower 14 to blow air into the illumination area according to the lighting control pattern. The blower 14 does not need to be integrated with the lighting system S1, and may be a standalone device with the function of blowing air, such as an electric fan or air conditioner.

[0051] Therefore, the lighting system S1 of variant example 3 can make a person H2 (child) in the illumination range of the lighting light (child's room R2) take a predetermined action more quickly by blowing air from the blower 14 in accordance with the lighting control pattern.

[0052] (3-4) Variation 4 The lighting system S1 of the fourth modification is equipped with a diffusion unit (diffuser 15) that diffuses a fragrance within the illumination range (see FIG. 8). The diffuser 15 is generally a device that atomizes and diffuses aromatic oil. However, the diffuser 15 of the fourth modification may diffuse an odor that is unpleasant to people within the illumination range.

[0053] The control unit 12 controls the diffuser 15 to diffuse the fragrance in the illumination range according to the lighting control pattern. Note that the diffusion unit (diffuser 15) does not need to be integrated with the lighting system S1, and may be, for example, a standalone device as a diffuser.

[0054] Therefore, the lighting system S1 of variant example 4 can cause a person H2 (child) who is within the illumination range of the lighting light (child's room R2) to take a predetermined action more quickly by diffusing fragrance from the diffusion section (diffuser 15) in accordance with the lighting control pattern.
