Abstract: The new standard MT1162-2011, implemented since January 2013, puts forward specific demands in color temperature of LED lamp. 8 kinds of LED lamp products were randomly picked and tested. However, the correlated color temperature values are not in line with the standard requirements. By analyzing the characteristics of white LED emission spectrum, the solution was proposed that the color temperature of LED light source could be reduced by attenuating light intensity of specific wavelength. The results showed that the color temperature of LED light source was reduced lower than 5 500 K under the premise that the luminous flux and display index were guaranteed in accordance with the requirements of the standard; moreover, the most significant decline of the color temperature could reach to 6 684 K.
