[0036] A smart human-centered lighting system that optimizes a user's biological rhythm and environment and a method for controlling the same, according to one embodiment of the present document, will be described in detail below with reference to the attached drawings.

[0038] First, with reference to FIG. 4, a smart human-centered lighting system that optimizes a user's biological rhythm and environment according to one embodiment of the present document will be described.

[0039] FIG. 4 is a block diagram illustrating a smart human-centered lighting system that optimizes a user's biological rhythm and environment according to one embodiment of the present document.

[0040] Referring to FIG. 4, a smart human-centric lighting (HCL) system (100) that optimizes a user's biological rhythm and environment according to one embodiment of the present document refers to a lighting device that is installed or located in a space such as a living room, room, or office to provide lighting to the user.

[0041] At this time, the smart human-centered lighting system (100) can provide lighting according to an operation mode set by a switch (300) or a user terminal (200) within the space.

[0042] A user terminal (200) is a terminal owned by a user residing in or located within a space, and can connect to a smart human-centered lighting system (100) via a wireless communication network to set the operation mode of the smart human-centered lighting system (100) and various information related thereto. At this time, the user can set the operation mode for each smart human-centered lighting system (100).

[0043] Here, the user terminal (200) may be a terminal equipped with memory means and equipped with a microprocessor to have computational capabilities, such as a laptop computer, tablet PC, personal digital assistant (PDA), web pad, smartphone, mobile phone, etc.

[0044] To explain further, the smart human-centered lighting system (100) can help improve the quality of sleep by finding the user's natural circadian rhythm by providing a lighting environment according to an auto mode that automatically changes brightness and color temperature according to the current time or a user mode that changes brightness and color temperature according to a mode selected by the user. That is, the smart human-centered lighting system (100) is a healthy system in which lighting is operated in a way that is personalized to the user for each space through an auto mode or user mode organized by quantifying the effect of indoor space lighting on the circadian rhythm based on a scenario of illuminance values ​​calculated based on the melanopic ratio.

[0046] Then, with reference to FIGS. 5 to 7, a smart human-centered lighting system that optimizes a user's biological rhythm and environment according to one embodiment of the present document will be described in more detail.

[0047] FIG. 5 is a block diagram for explaining the configuration of the smart human-centered lighting system illustrated in FIG. 4, FIG. 6 is a diagram for explaining an example of the smart human-centered lighting system illustrated in FIG. 4, and FIG. 7 is a diagram for explaining an operation mode according to an embodiment of the present document, where (a) represents an auto mode and (b) represents a user mode.

[0048] Referring to FIGS. 5 and 6, the smart human-centered lighting system (100) may include a main light source module (110), a sub light source module (120), and a lighting control module (130).

[0049] The main light source module (110) can provide direct lighting to the lighting space by emitting main LED light downward.

[0050] The sub-light source module (120) is positioned around the main light source module (110) and can provide indirect lighting to the lighting space by emitting sub-LED light downward.

[0051] The lighting control module (130) can control the operation of the main light source module (110) according to one of the modes, auto mode and user mode.

[0052] Here, the auto mode can automatically change the brightness and color temperature according to the current time. That is, as illustrated in FIG. 7 (a), the auto mode can consist of an awaken care mode that changes the brightness and color temperature based on the wake-up time set by the user for a refreshing start to the day, a sleep care mode that changes the brightness and color temperature based on the bedtime set by the user for a recovery time to help with deep sleep, and a day care mode that changes the brightness and color temperature between the wake-up time and bedtime to maintain an energetic daily routine.

[0053] To explain in more detail, the awaken care mode may be a mode that gradually increases brightness and color temperature using an awaken care reference value containing preset brightness and color temperature values, from a preset time before the wake-up time until the wake-up time, so that the brightness and color temperature values ​​according to the awaken care reference value are reached at the wake-up time. Here, the awaken care reference value may have a brightness value of 80% dimming and a color temperature value of 3500K. And, the sleep care mode may be a mode that gradually decreases brightness and color temperature from the brightness and color temperature values ​​according to the sleep care reference value using a sleep care reference value containing preset brightness and color temperature values, from a preset time before the sleep time until the sleep time. Here, the sleep care reference value may have a brightness value of 40% dimming and a color temperature value of 3000K. In addition, the day care mode may be a mode that, using wake care reference values ​​and sleep care reference values, gradually increases the brightness and color temperature from the brightness and color temperature values ​​according to the wake care reference value to the maximum brightness and color temperature values ​​according to the day care reference value from the wake-up time until a preset time before the bedtime, and then gradually decreases the brightness and color temperature to reach the brightness and color temperature values ​​according to the sleep care reference value. Here, the maximum brightness value of the day care may be 100% dimming, and the maximum color temperature may be 6000K.

[0054] In addition, the user mode can change the brightness and color temperature according to the mode selected by the user. That is, as illustrated in FIG. 7(b), the user mode can represent one of the following modes: a meditation mode representing a light concept that leads to a calm mind, a relaxation mode representing a light concept that relieves tension in the body, a living mode representing a light concept that reduces eye strain, a working mode representing a light concept that awakens the brain and increases attention, and a learning mode representing a light concept that boosts cognitive ability and motivation.

[0055] Here, meditation mode may be a mode with a brightness dimming of 10% to 15% and a color temperature of 2800K. And, relaxation mode may be a mode with a brightness dimming of 20% to 45% and a color temperature of 3500K. And, living mode may be a mode with a brightness dimming of 45% to 80% and a color temperature of 4000K. And, working mode may be a mode with a brightness dimming of 80% to 90% and a color temperature of 5000K. And, learning mode may be a mode with a brightness dimming of 90% to 100% and a color temperature of 6000K.

[0056] Additionally, when the lighting control module (130) controls the operation of the main light source module (110) according to the user mode, it can additionally control the operation of the sub light source module (120) so that the color of the sub LED light changes according to the user mode.

[0057] Here, the meditation mode may be a mode in which the color of the sub-LED light consists of at least one of blue and orange or a mixed gradient thereof. And, the relaxation mode may be a mode in which the color of the sub-LED light consists of green. And, the living mode may be a mode in which the color of the sub-LED light consists of blue. And, the working mode may be a mode in which the color of the sub-LED light consists of at least one of yellow and green or a mixed gradient thereof. And, the learning mode may be a mode in which the color of the sub-LED light consists of at least one of yellow and blue or a mixed gradient thereof.

[0059] Then, with reference to FIG. 8, an example of an auto mode according to one embodiment of the present document will be described.

[0060] FIG. 8 is a drawing for explaining an example of an auto mode according to one embodiment of the present document.

[0061] As previously explained, auto mode may consist of an awaken care mode that changes brightness and color temperature based on the wake-up time set by the user for a refreshing start to the day, a sleep care mode that changes brightness and color temperature based on the bedtime set by the user for a recovery time to aid deep sleep, and a day care mode that changes brightness and color temperature between wake-up and bedtimes to maintain an energetic daily routine.

[0062] That is, when auto mode is selected, the lighting of the smart human-centered lighting system (100) installed in the living room and room ceilings automatically changes moment by moment and achieves brightness and color temperature similar to natural light. Through this, the lighting user experiences falling asleep easily and waking up naturally while maintaining a stable biological rhythm.

[0063] For example, referring to Fig. 8, when the wake-up time is set to "AM 7:00" and the bedtime is set to "PM 11:00", the wake-up care mode may be a mode that gradually increases the brightness and color temperature using the wake-up care reference value (brightness value = 80% dimming / color temperature value = 3500K) from 6:30 AM to 7:00 AM, 30 minutes before 7:00 AM, so that the brightness value (80% dimming) and color temperature value (3500K) according to the wake-up care reference value are reached at 7:00 AM.

[0064] In addition, the sleep care mode may be a mode that gradually reduces the brightness and color temperature from the brightness value (dimming 40%) and color temperature value (3000K) according to the sleep care standard value (brightness value = dimming 40% / color temperature value = 3000K) using the sleep care standard value (brightness value = dimming 40%), that is, from 10:30 PM to 11 PM, 30 minutes before 11 PM.

[0065] And, the day care mode may be a mode that uses the wake-up care reference value and the sleep care reference value to gradually increase the brightness and color temperature from the brightness value (dimming 80%) and color temperature value (3500K) according to the wake-up care reference value to the day care maximum brightness value (dimming 100%) and color temperature maximum value (6000K) from 7:00 AM to 10:30 PM, which is 30 minutes before 11:00 PM, and then gradually decreases the brightness and color temperature to reach the brightness value (dimming 40%) and color temperature value (3000K) according to the sleep care reference value.

[0067] Then, with reference to FIG. 9, an example of a user mode according to one embodiment of the present document will be described.

[0068] FIG. 9 is a drawing for explaining an example of a user mode according to one embodiment of the present document, showing brightness and color temperature.

[0069] User mode supports five modes: meditation, relaxation, living, working, and learning. Each mode is set to optimal values ​​tailored to individual activities to relieve tension, reduce eye strain, and enhance attention. Of course, users can also finely adjust additional controls as needed.

[0070] That is, as previously explained, user mode can represent one of the following modes: meditation mode, which represents a light concept that leads to a calm mind; relaxation mode, which represents a light concept that relieves tension in the body; living mode, which represents a light concept that reduces eye strain; working mode, which represents a light concept that awakens the brain and increases attention; and learning mode, which represents a light concept that boosts cognitive ability and motivation.

[0071] For example, referring to Fig. 9, the meditate mode may be a mode with a brightness value of 10% to 15% dimming and a color temperature of 2800K. In this case, the recommended brightness value for the meditate mode may be 20% dimming.

[0072] Also, the relaxaton mode may be a mode with a brightness value of 20% to 45% dimming and a color temperature of 3500K. In this case, the recommended brightness value for the relaxaton mode may be 32% dimming.

[0073] Also, living mode may be a mode with a brightness value of 45% to 80% dimming and a color temperature of 4000K. In this case, the recommended brightness value for living mode may be 60% dimming.

[0074] Also, working mode may be a mode with a brightness value of 80% to 90% dimming and a color temperature of 5000K. In this case, the recommended brightness value for working mode may be 84% dimming.

[0075] Also, the learning mode may be a mode with a brightness value of 90% to 100% dimming and a color temperature value of 6000K. In this case, the recommended brightness value for the learning mode may be 96% dimming.

[0077] Then, with reference to FIGS. 10 to 14, an example of indirect lighting according to one embodiment of the present document will be described.

[0078] The smart human-centered lighting system (100) can produce color therapy by using indirect lighting, that is, sub-LED light emitted into the lighting space through a sub-light source module (120), according to a user mode selected by the user.

[0079] A. User mode: Meditation mode

[0080] FIG. 10 is a drawing for explaining an example of indirect lighting in a meditation mode according to one embodiment of the present document, where (a) indicates brightness and color temperature, (b) indicates color, and (c) indicates an example of indirect lighting.

[0081] Referring to FIG. 10, the meditate mode may be a mode in which the color of the sub-LED light is blue, which is effective for relieving tension and stress and represents calmness, sincerity, peace, relaxation, and stability, and orange, which is effective for promoting blood circulation and heart rate and represents vitality, creativity, joy, and an optimistic attitude, or a mixed gradient thereof. In this case, the meditate mode may be a mode in which the brightness value of the sub-light source module (120) is dimmed to 20% and the color temperature value of the sub-light source module (120) is 2800K.

[0082] For example, as illustrated in Fig. 10 (c), the depth and tranquility of a calm and introspective deep blue can create a beautiful contrast with the warm 2800K lighting of a meditation space, thereby creating a quiet and contemplative atmosphere. Additionally, terracotta, rich brown, or ochre earth tones can harmonize with the lighting to help stabilize the space into a peaceful and comfortable environment.

[0083] B. User Mode: Relaxation Mode

[0084] FIG. 11 is a drawing for explaining an example of indirect lighting in a rest mode according to one embodiment of the present document, where (a) indicates brightness and color temperature, (b) indicates color, and (c) indicates an example of indirect lighting.

[0085] Referring to FIG. 11, the relaxation mode may be a mode in which the color of the sub-LED light is green, which helps relieve tension or has a calming effect and represents tolerance, safety and protection, freedom, etc. In this case, the relaxation mode may be a mode in which the brightness value of the sub-light source module (120) is dimmed to 32% and the color temperature value of the sub-light source module (120) is 3500K.

[0086] For example, as illustrated in Fig. 11 (c), green has a calming and restorative effect, making it ideal for relaxation spaces, and can create a calm and peaceful atmosphere when combined with a color temperature of 3500K. Additionally, beige, grayish-brown, and light brown can provide a sense of color balance by creating a cozy atmosphere and a feeling of being connected to nature.

[0087] C. User mode: Living mode
