Notes）

・(x,y) is chromatic coordinates in CIE color diagram. Rank areas are shown in Sheet 4.

・Tolerance of chromaticity is +/-0.02.

・The correlated color temperature for Rank B varies from 12,000K to infinity.

For Rank P, it varies from 5,000K to 12,000K. For Rank Y, it varies from 3,000K to 5,000K.

For Rank O, it varies from 1,600K to 3,000K.

・The narrower color ranks which the customer requires can be offered by a special contract

between the two parties.

・The color of White LED is changed a little by an operating current

・A typical light emission spectrum of the white LED (Rank P) is shown in sheet 1.
