Abstract
This invention provides a full-spectrum adjustable color temperature LED and a luminaire incorporating the same. When the color temperature is greater than or equal to 2200K and less than 5000K, its emission spectrum has at least one peak in the range of 530-830nm, and the intensity of the highest peak in the range of 380nm-530nm is ≤ that of the highest peak in the range of 530nm-830nm, with the difference between the two peak intensities increasing as the color temperature decreases. When the color temperature is ≥5000K, its emission spectrum has at least one peak in the range of 380nm-530nm; the intensity of the highest peak in the range of 530nm-830nm is ≤ that of the highest peak in the range of 380nm-530nm, with the difference between the two peak intensities decreasing as the color temperature decreases; and it has at least two peaks between 380nm and 480nm. Each color temperature of this LED can be adjusted to the ERP or ANSI standard center point, or the blackbody trajectory line, and each color temperature has a fitting degree >98% to the solar spectrum.
