[0040] FIG. 1 shows the configuration of a lighting system capable of reducing melatonin suppression according to a first embodiment of the present invention. The lighting system 1 includes: a control unit 2 for controlling lighting; a lighting device 3 controlled by the control unit 2 to perform conversion from normal lighting to melatonin lighting; a lighting switch 6 for switching on and off through the user's operation Turn on, turn off, or dim the lighting device 3; the alarm clock 7; the display unit 8; and the memory 14 for storing the time when the user intends to fall asleep and the reference time for calculating the time to start melatonin lighting. The control unit 2 comprises a lighting control subunit 15 for controlling the transition from normal lighting to melatonin lighting, wherein the lighting control subunit 15 is preferably software installed in the control unit 2 . Melatonin lighting has a range of illuminance, for example, below 100 lux including complete...

[0045] According to a second embodiment of the present invention, there is provided a lighting system capable of evaluating sleep quality by evaluating smoothness of falling asleep, sleep maintenance, and quality of awakening.

[0046] First, smoothness of falling asleep can be quantitatively evaluated by measuring sleep latency (ie, the amount of time required to fall asleep). In particular, the sleep intention time (ie, the time when the user intends to fall asleep) is set by detecting the operation of an alarm clock or a lighting switch. Also, the sleep onset time is obtained by measuring the user's body motion and determining the time when the body motion drops below a certain level as the sleep onset time. Finally, the sleep latency is calculated by obtaining the time difference between the sleep intention time and the sleep onset time, and the sleep latency thus calculated is used as an index regarding the smoothness of falling asleep.

[0047] Second, sleep maintenance...

[0060] Fig. 8 shows a sleep management system 9 comprising a lighting system 1" according to a third embodiment of the invention, wherein the lighting system 1" is identical to the lighting system 1' except that it does not include a memory 14. Sleep management The system 9 includes: a lighting system 1″; a data storage unit 10 for storing the results of the sleep assessment; a communication unit for sending the results of the sleep assessment to the terminal device 11 via a communication channel; and a data processing unit 13 capable of For example, the Internet communicates with the terminal device 11 . The data storage unit 10, constituted by a general-purpose memory device, does not need to be embedded in the lighting system 1". Preferably, the data storage unit 10 is connected to the lighting system 1"on-line. The terminal 11 is, for example, a mobile phone, a PDA (Personal Digital Assistant) or a fax. The communication unit 12 is an interface for exchanging data with th...

Abstract

A lighting system (1), comprising: a lighting device (3); an operating device (6) for the user to operate when the user intends to fall asleep; a control unit (2) for operating the operating device Time detection measures the start time of sleep latency, which is the period of time from the time the user intends to fall asleep to the time the user falls asleep; and a memory unit (14) for storing a reference time based on the time measured by The control unit is obtained by detecting the start time of the sleep latency. The control unit includes a lighting device control (15) subunit that performs lighting control to reduce the user's melatonin suppression starting from a predetermined time before the reference time stored in the memory.

Description

technical field [0001] The present invention relates to lighting systems, and more particularly, to lighting systems capable of assessing and / or improving the quality of sleep of their users. Background technique [0002] Various techniques have been developed for investigating the user's physical state from bedtime to waking up to determine whether the user fell asleep and / or to evaluate the user's sleep quality (see, for example, Japanese Patent Application Publication No. H5-245148; Japanese Patent Application Laid-Open No. H5-245148; Application Publication No.H5-337103; Japanese Patent Application Publication No.H5-095934; Japanese Patent Application Publication No.H5-095935; Japanese Patent Application Publication No.H5-111474; Japanese Patent Application Publication No.H6 -098863; and Japanese Patent Application Publication No. 2000-316832). [0003] In addition, it is well known that light suppresses the secretion of melatonin, the sleep hormone secreted at night fr...
