LED-Based Dental Exam Lamp with Variable Chromaticity

摘要

Abstract An electrically powered light source including a light emitting diode (LED) having variable chromaticity, which is adapted for use in a dental operatory. A dental operatory lamp includes at least two user selectable light spectra, one of said spectra providing white light with color temperature in the range 4000'K - 6000'K and one spectra having reduced output in the wavelength range 400-500 nm. 116 130 8ll
