  • Publication number: 20210106843
    Abstract: An infant care device that selectively controls the amount of visible light that is transmitted into the interior of an enclosure while allowing the transmission of light within certain wavelengths. The infant care device includes an enclosure that includes light dimmable technology that adjusts the transparency of the enclosure based upon control signals from a primary controller. The primary controller is able to cycle between day/night on a manual or automatic basis to selectively control the amount of light that reaches the infant patient. The light dimming technology used on the enclosure allows the transmission of light within a phototherapy wavelength spectrum. The controller thus controls the transparency of the enclosure to at least partially reduce or increase the light reaching the infant while allowing phototherapy.
