Description
本揭露是有關於一種光源裝置及顯示裝置,且特別是有關於一種可提供不同生理刺激光線的光源裝置及顯示裝置。The present disclosure relates to a light source device and a display device, and in particular to a light source device and a display device that can provide different physiological stimulation lights.
隨著愛迪生(Thomas Alva Edison)發明電燈泡,電力所產生的光源不僅點亮了黑夜,亦點亮了人類的文明,藉著這種人工光源,人類得以利用夜晚的時間,因而更進一步地帶動了科技與教育的發展。而在光源對生理刺激的影響研究上,Yasukouchi研究發現夜間高色溫的光源比低色溫的光源較抑制褪黑激素的分泌。其次從2001年以來,Branard的研究對人眼與生理影響(biological effect)的關係,更進一步指出說明光源與褪黑激素的分泌以及生理影響的關係,並如圖1繪示出光源與生理刺激對應曲線(2001 Action Spectrum for Melatonin Regulation in Humans: Evidence for a Novel Circadian Photoreceptor)。而進一步可以說明光源不同波長(400nm-550nm)將不同影響生理刺激(circadian stimulus,CS),判斷光源對人體的生理刺激影響程度,因此,若於夜間或白天使用光源時,需要藉由適合光源的頻譜組成,提供適切的人工照明光源。With the invention of light bulbs by Thomas Alva Edison, the light source generated by electricity not only lights up the night, but also lights up human civilization. With this artificial light source, human beings can use the time of the night, which has further driven Technology and education development. In the study of the influence of light sources on physiological stimuli, Yasukouchi found that light sources with high color temperature at night inhibited melatonin secretion more than light sources with low color temperature. Secondly, since 2001, the relationship between Branard’s research on the human eye and biological effects has further pointed out the relationship between light sources and melatonin secretion and physiological effects, and the light sources and physiological stimuli are shown in Figure 1. Correspondence curve (2001 Action Spectrum for Melatonin Regulation in Humans: Evidence for a Novel Circadian Photoreceptor). Furthermore, it can be explained that different wavelengths of the light source (400nm-550nm) will affect the physiological stimulus (circadian stimulus, CS) differently, and determine the degree of the influence of the light source on the human body's physiological stimulus. Therefore, if the light source is used at night or daytime, it is necessary to use a suitable light source The spectrum composition provides appropriate artificial lighting source.

圖2A是本揭露之一實施例中的光源裝置的示意圖,圖2B是依照圖2A實施例中的光源裝置的一種變化,圖2C是依照圖2B實施例中的光源裝置所發出之光線的相對光強度與光波長的光譜示意圖,請參照圖2A至圖2C,在本實施例中,光源裝置100包括一發光模組110以及一控制單元120。發光模組110提供一光線B。在本實施例中,光線B所代表的意義為發光模組110所發出的光,可具有發散角度,而非限定於特定的傳遞方向。控制單元120用以切換發光模組110所發出的光線B為一第一光線L1或一第二光線L2。其中,第二光線L2的生理刺激值(circadian stimulus/ photometry, CS/P) 小於第一光線L1的生理刺激值,且第二光線L2與第一光線L1的色溫實質上相同。藉此,光源裝置100可在不易讓使用者察覺到光色溫變化的情形下,依照實際使用環境、時間及目的以選擇提供具有高生理刺激的第一光線L1或是低生理刺激的第二光線L2,以維持使用者自然的生理週期並同時提供足夠的光源。2A is a schematic diagram of a light source device in an embodiment of the disclosure, FIG. 2B is a variation of the light source device in the embodiment of FIG. 2A, and FIG. 2C is a relative light emitted by the light source device in the embodiment of FIG. 2B. Please refer to FIGS. 2A to 2C for schematic diagrams of light intensity and light wavelength spectrum. In this embodiment, the
詳細而言,在本實施例中,生理刺激值(CS/P)的定義如下式所示:
其中,CS(λ)代表人類的生理函數,P(λ)代表人類的明視覺函數,P0λ
代表混光完成後的光譜,而CS代表混光完成後光譜的生理刺激值,P代表混光完成後光譜的強度值。其中,有關於明視覺函數P(λ)是依照國際照明委員會(Commission internationale de l'éclairage,CIE)的定義。並且人類的生理函數CS(λ)可參照Professor Brainard所提出的Action spectrum(1997),如圖1所示,Mark Rea所提出的人體非視覺生理函數(2005)以及German pre-standard DIN V所提出的生理函數,並且本揭露之光源裝置100可適用於各種生理函數。並且,圖3是美國國家標準協會(American national standard institute,ANSI)所定義的同色溫的色座標型態的示意圖,請參照圖3,在本實施例中,同色溫的定義是依照美國國家標準協會的定義。換言之,依照此一標準設計之同色溫的光源,對人眼而言的顏色差異不易察覺。其中,圖3示意圖中所繪示的美國國家標準協會定義的色座標型態的詳細座標值請參照表1如下:
表1
詳細而言,請參照圖2A,控制單元120可使發光模組110於多個發光模式間切換,這些發光模式包含一第一生理刺激模式與一第二生理刺激模式,發光模組110包括多個發光單元D,這些發光單元D可包括電致發光元件、光致發光元件或其組合。其中發光單元D包括至少一第一發光單元D1、至少一第二發光單元D2與至少一第三發光單元D3,第一發光單元D1提供一第一子光線W1,第二發光單元D2提供一第二子光線W2,且第三發光單元D3提供一第三子光線W3。其中,第一子光線W1的至少一波峰值範圍可大於420nm且小於480nm,第二子光線W2的至少一波峰值範圍可大於480nm且小於540nm,第三子光線W3的至少一波峰值範圍可大於540nm。In detail, referring to FIG. 2A, the
當控制單元120使發光模組110切換至第一生理刺激模式時,控制單元120使這些發光單元D的第一部分P1提供第一光線L1,其中第一光線L1可包括第一子光線W1與第二子光線W2,且當控制單元120使發光模組110切換至第二生理刺激模式時,控制單元120使這些發光單元D的第二部分P2提供第二光線L2,其中第二光線L2可包括第一子光線W1與第三子光線W3,且第一光線L1與第二光線L2的色溫實質上相同,因此可在不影響使用者色溫感覺的情況下改變生理刺激值以符合不同的需求。When the
此外,圖2B中的光源裝置100’與圖2A所繪示的光源裝置100相似,其中圖2B中,各發光單元對應提供光線波峰值範圍如圖2A實施例說明範圍,然而不同之處在於,圖2B中的光源裝置100’的第一部分P1’可更包括第三發光單元D3。In addition, the light source device 100' in FIG. 2B is similar to the
其中,在第一生理刺激模式下,第一部分P1’所提供的第一光線L1’可包括第一子光線W1、第二子光線W2與第三子光線W3。而在第二生理刺激模式下,第二部份P2’所提供的第二光線L2’可包括第一子光線W1與第三子光線W3。In the first physiological stimulation mode, the first light L1' provided by the first part P1' may include a first sub-light W1, a second sub-light W2 and a third sub-light W3. In the second physiological stimulation mode, the second light L2' provided by the second part P2' may include a first sub-light W1 and a third sub-light W3.
其中,圖2B完成混光後之頻譜如圖2C所示,由於第二子光線W2的生理刺激值大於第三子光線W3的生理刺激值,因此第一光線L1’雖與第二光線L2’為相同的色溫3000K,由於其混光光譜不同,因此生理刺激值不同,第一光線L1’其光譜如圖2C中的混光光譜曲線SH1,生理刺激值CS/P經計算後約為0.43,而第二光線L2’ 其混光光譜如圖2C中的光譜曲線SL1,其生理刺激值CS/P經計算後約為0.27,亦即上式計算出的CS/P,其中第一光線L1’的生理刺激值經計算後約為第二光線L2’的生理刺激值的159%。藉此,可使得第二光線L2’與第一光線L1’的生理刺激值有更顯著的差異。而可達到上述之目的,本揭露不以此為限。The spectrum after mixing light in FIG. 2B is as shown in FIG. 2C. Since the physiological stimulation value of the second sub-ray W2 is greater than the physiological stimulation value of the third sub-ray W3, the first light L1′ and the second light L2′ It is the same color temperature of 3000K. Due to the different light mixing spectrum, the physiological stimulation value is different. The spectrum of the first light L1' is shown as the light mixing spectrum curve SH1 in FIG. 2C. The calculated physiological stimulation value CS/P is about 0.43. The mixed light spectrum of the second light L2' is shown as the spectral curve SL1 in FIG. 2C, and the physiological stimulus value CS/P is calculated to be about 0.27, which is the CS/P calculated by the above formula, where the first light L1' The physiological stimulation value of is calculated to be about 159% of the physiological stimulation value of the second light L2'. Thereby, the physiological stimulation value of the second light L2' and the first light L1' can be more significantly different.
