Abstract:
1. A day/night switchable light adjusting device for maintaining normal melatonin secretion of human body, comprising: a first panel comprising at least one first lighting unit and a first reflecting surface, wherein the first lighting unit is an organic light emitting diode panel and the first reflecting surface is disposed underneath the first lighting unit, and the first lighting unit emitting a first wavelength light; a second panel, one side of the second panel is connected with one side of the first panel and an angle and at least one opening are formed between the first panel and the second panel, the second panel comprising at least one second lighting unit and a second reflecting surface, each second lighting unit comprising two sub lighting units, wherein the two sub lighting units are organic light emitting diode panels and the second reflecting surface is disposed underneath the two sub lighting units, the two sub lighting units emitting a first sub wavelength light and a second sub wavelength light respectively, and the first sub wavelength light and the second sub wavelength light are mixed for forming a second wavelength light; a light collecting component disposed on the opening; and a control unit electrically connected to the first lighting unit and the second lighting unit, the control unit adjusting the first wavelength light and the second wavelength light with a day/night variation respectively, wherein the first wavelength light and the second wavelength light are mixed for forming a white light with various color levels, and a blue region light or a cyan region light of the white light is varied with the day/night variation; wherein the first reflecting surface and the second reflecting surface reflect the first wavelength light and/or the second wavelength light, and the first wavelength light, a reflected light of the first wavelength light, the second wavelength light, and a reflected light of the second wavelength light are mixed on the light collecting component; wherein the first reflecting surface comprises a first portion being exposed out and a second portion being covered by the first lighting unit, and the second reflecting surface comprises a first portion being exposed out and a second portion being covered by the second lighting unit; wherein the first wavelength light or the second wavelength light is reflected by the first portions and the second portions of the first reflecting surface and the second reflecting surface; wherein the light intensity of the blue region light or the cyan region light is decreased from a day time to a night time.
