以往照明影響人體的研究,大多探討短時間內於一般照度或色溫度環境下,對人體生理的影響,對於使用高照度高色溫度照明的場所影響人體的情形,並未深入研究,因此,本研究篩選二十一位22~30歲健康的受測者,在精確控制環境變因的實驗室內,接受實驗組2000Lux-4000K、2000Lux-6500K及對照組500Lux-4000K、500Lux-6500K等四種照明變化的刺激,運用良導絡系統量測其經絡反應。測定結果經統計分析後,用以評估在長時間(3.5小時)於高照度高色溫度照明狀態下,受測者生理所受的影響。 實驗結果顯示,不同時刻、不同照明環境會影響不同的人體經絡,特別在高照度照明狀態下,以心包經、膀胱經與脾經較易受到影響。而且在長時間測定後發現,開燈90分鐘內高色溫度(6500K)照明對人體經絡的影響較大,而開燈90分鐘後則以高照度(2000Lux)照明的影響較大。但是,若處於高照度高色溫度(2000Lux-6500K)照明狀態下,則大部分人體經絡於開燈瞬時及開燈後30~45分鐘起即受到影響,顯示照度及色溫度爲影響人體生理反應的重要影響因子。
Most of the past studies of the lighting effect on human body focused only on discussions of the short term effect of lighting or color temperature changes on human physiological responses, failing to investigate the effect produced on human body by use of high illuminance and high color temperature lighting. In this study, 21 healthy participants between 21~30 years old were selected. We stimulated them with four different lighting conditions in 2000Lux-4000k, 2000Lux-6500k in contrast with 500Lux-4000k, and 500Lux-6500k respectively under precise controlled indoor environment qualities. The Ryodoraku measuring system was used to measure the human meridian responses for a duration of 3.5 hours. The statistically analyzed results are used to assess the participants' physiological changes. The results showed that the effects on human meridians in different lighting with different duration were inconsistent. In the high illuminance lighting, Pericardium Meridian, Bladder Meridian, and Spleen Meridian were easily affected. In addition, with a prolonged illumination, we discovered that after lighting in 90 minutes, the human meridians were obviously affected with the high illuminance lighting (2000Lux). Prior to that, the effect of high color temperature lighting (6500K) was greater. However, on a high illuminance and high color temperature lighting (2000Lux-6500k), the majority of meridians were affected when the light was turned on initially and then within 30-45 minutes afterwards. The results showed that illuminance and color temperature were important influence factors of human physiological reaction.
