Embodiment Construction

[0040] In a preferred embodiment, we collected data from Brainard, G.C., Hanifm, J.P., Greeson, J.M., Byrne, B., Glickman, G., Gerner, E., Rollag, M.D. (see Action Spectrum for Melatonin Regulation in Humans: Evidence for a Novel Circadian Photoreceptor, The Journal of Neuroscience 21(16), pp. 6405-6412 (2001)) and Thapan, K., Arendt, J., Skene, D.J. (see Rapid Report-An action spectrum for melatonin suppression : evidence for a novel non-rod, non-cone photoreceptor system in humans, Journal of Physiology, 535.1, pp. 261-267 (2001)) measured independent data. These measurements have been used to characterize the spectral response of melatonin suppression, the Melatonin Suppression Action Spectrum (MSAS) as figure 1 shown in the middle square.

[0041] In the specification of the present invention, the transmittance is expressed such that the transmittance 1 corresponds to the total transmittance of light without absorption or reflection. A transmission of 0 corresponds to n...

Abstract

Multilayer optical interference filter for filtering light constructed by alternating materials having different refractive indexes, with layer thicknesses calculated in order to achieve a transmittance in accordance with the inverse of the Melatonin Suppression Action Spectrum.

Description

technical field [0001] The present invention relates to a light filtering device, in particular to a device for filtering light from a broad-spectrum light-emitting diode device to reduce the negative impact of LEDs on starry sky observation, human health, road safety, plant and insect mortality. Background technique [0002] White light-emitting diodes (hereinafter referred to as "LEDs" or "LEDs") have revolutionized technology in lighting equipment. LED technology has many advantages over conventionally used lighting technologies. A major advantage of LEDs is their extremely long lifetime, which limits the maintenance costs associated with their use. Another advantage of LEDs is that they can be easily controlled or adjusted. LEDs provide great luminous efficiency. [0003] The current maximum luminous efficacy is achieved by LEDs emitting in the visible blue spectrum. To produce white light using LEDs, the most efficient approach involves exciting a phosphorous coatin...
