- benzopyran derivatives, coumarin derivatives, cyanocoumarin derivatives, and the like can also be advantageously used as the illuminant used for the organic EL element used as the light source of the lighting device (for example, JP-A-2005-247976).
- control group 1 the LED that radiates near ultraviolet rays is not turned on
- control group 2 the other is a 15 W warm white fluorescent lamp (color temperature of about 3500) of 100V. What was turned on at the rated voltage was used as illumination (control group 2), and was allowed to spend one week as in the test group. In the light emitted from the fluorescent lamp used in the control group 2, the radiation energy of near ultraviolet rays with respect to visible light was about 1%.
- Urine from each subject was collected before the start of the test and on the last day of the test period, and 6M hydrochloric acid was added and stored at -20 ° C.
- the increase in urinary serotonin was lower than 5% in subjects (control groups 1 and 2) who spent under LED light sources and fluorescent lamps that contained almost no near ultraviolet rays.
- the urinary serotonin concentrations before and after were similar.
- subjects (test groups 1 to 4) who spent under ultraviolet light containing 3% or more of the radiant energy of visible light the urinary serotonin concentration increased by about 20% or more compared to before the test.
- the rate of increase of urinary serotonin increased as the near-ultraviolet intensity for visible light increased.
- the increase rate of urinary serotonin was 30 to 40% when the UV intensity against visible light was 5% or more.
- the human serotonin nervous system is activated by irradiating light containing 3-15%, preferably 5-10%, of near-ultraviolet light with respect to the radiant energy of visible light.
- the lighting apparatus activates the serotonin nervous system and reduces the factor that causes a so-called “clear” state.
- Example 2 Effect of lighting of the present invention on noradrenaline levels> A panel test was conducted with 20 adult males (ages 20 to 50). That is, the subjects were randomly divided into two groups of 10 people, and one group was a lighting device in which the near-ultraviolet energy of the illumination used in Experiment 1 was adjusted to 5% of visible light. Using it for lighting, a simple addition work by the Kraepelin test was performed for 1 hour in an environment where the metronome sounded as a work load (test area). Venous blood was collected before and after work load and blood noradrenaline levels were measured.
- the other two groups use the same illumination as in the test section except that the near-ultraviolet light source is not turned on for the light at the time of lighting, one is not turned on in the dark (control section 1), and the other is near-ultraviolet for the suggestion.
- the animals were reared under the condition that only the light source was irradiated with the same intensity as the test group. In either case, the illuminance on the cage floor at the time of light was about 500 lux.
- each mouse was observed for aggression by the following method.
- each mouse is placed in a transparent plastic container, and it is made one-to-one hostile with the same-week-old ddy mouse that is normally raised by freely ingesting powdered feed and water.
- the number of times performed during 5 minutes was counted.
- the aggression in the test group and the control group 2 was determined as a relative value of the number of attacks when the number of attack actions in the control group 1 was 100, and the average value of the aggression in each group is shown in Table 2.
- the frontal cortex was removed from the brain of each mouse after the end of the aggressiveness measurement, homogenized in a buffer solution containing 0.1% ascorbic acid, and stored at ⁇ 20 ° C.
- the lighting device of the present invention has the effect of activating the serotonin nervous system of animals to reduce the aggressiveness, and the effect is not visible light or near ultraviolet light alone, but visible light and near ultraviolet light alone. It was found that it can be achieved by irradiating light including both.
- the lighting device of the present invention can be used as nighttime lighting in daily living space, activates the serotonin nervous system, and does not substantially increase blood noradrenaline levels, including humans. It is an illuminating device which has the effect which suppresses the aggressiveness of an animal.
- the present invention is beneficial to society in that it can be used to reduce the factors that cause impulsive / aggressive so-called “crisp” conditions and to suppress the abnormal behavior and crimes. It is an invention.

本発明による照明装置がヒトのセロトニン神経系に与える影響を調べるため、成人男性60名(年齢20乃至50歳)によるパネルテストを行なった。すなわち、被験者を無作為に10人ずつ6つのグループに分け、4グループについては、夜間の照明として放射エネルギー320nm~380nmの近紫外線のを可視光線の放射エネルギーに対してそれぞれ3,5,10,15%に調整した実施態様1の照明装置をスタンド照明に用いて、机面における照度を700ルクスとし、1日2時間以上の読書等のデスクワークをして1週間過ごしてもらった(試験区1~4)。残りの2グループについては、一方は近紫外線を輻射するLEDを点灯させない以外は試験区と同じ条件で(対照区1)、もう一方は15Wの温白色蛍光灯(色温度約3500)を100Vの定格電圧で点灯させたものを照明として用い(対照区2)、試験区と同様に1週間過ごしてもらった。なお、対照区2に用いた蛍光灯が輻射する光において、可視光線に対する近紫外線の放射エネルギーは約1%であった。試験開始前、及び試験期間最終日に各被験者の尿を採取し、6M塩酸を加えて-20℃で保存した。解凍後、市販のセロトニン測定試薬「Serotonin EIA」(Labor Diagnostika Nord社製)を用いて尿中セロトニン濃度を測定した。次式により試験前の尿中セロトニン濃度に対する試験後のセロトニン濃度の増加率を求め、グループ毎にその平均値を算出したものを、表1に示した。
増加率(%)={(試験後のセロトニン濃度-試験前のセロトニン濃度)/試験前のセロトニン濃度} × 100
成人男性20名(年齢20乃至50歳)によるパネルテストを行なった。すなわち、被験者を無作為に10人ずつ2つのグループに分け、1つのグループについては、実験1で用いた照明のうち、近紫外線のエネルギーを可視光線に対して5%に調整した照明装置をスタンド照明に用いて、作業負荷としてメトロノームの音が鳴る環境下でクレペリンテストによる単純加算作業を1時間行なってもらった(試験区)。作業負荷前および終了後に静脈血を採血し、血中ノルアドレナリンレベルを測定した。残りのグループにおいては、照明として実験1で用いた照明のうち、近紫外線LEDを点灯させない以外は試験区と同様の試験を行なった(対照区)。血中ノルアドレナリンレベルの測定は株式会社SRLに依頼した。得られた測定値をグループ毎に平均して求めた値を表2に示す。
7週齢のBALB/C系統のマウスの雄30匹を、10匹ずつの3グループに分け、12時間ずつの明暗サイクルの環境下で、粉末飼料および水を自由摂取させて1週間隔離飼育した。1つのグループは、明時の照明に実施態様1に記載の本発明の照明装置において近紫外線の放射エネルギーを可視光線に対して10%としたものを使用し、暗時には何も点灯させない条件で飼育した(試験区)。他の2グループは、明時の照明に近紫外線光源を点灯させない以外は試験区と同じ照明を用い、一方は暗時には何も点灯させず(対照区1)、もう一方は、暗示に近紫外線光源のみを試験区と同じ強度で照射させた条件で飼育した。いずれも明時のケージ床における照度を約500ルクスとした。
