    • A lighting device (100) including at least one light emitting diode (LED 101) and a wavelength converter (120) is described. The wavelength converter includes a supporting plate (103) and a plurality of first host sites (104) and second host sites (104) disposed directly on a surface of the supporting plate. Each of the plurality of first host sites consists of a first matrix (105) and a plurality of first quantum dots (108) dispersed in the first matrix. The first quantum dots have a first common emission peak wavelength. Each of the plurality of second host sites consists of a second matrix (105) and a plurality of second quantum dots (106) dispersed in the second matrix. The second quantum dots have a second common emission peak wavelength. The second common emission peak wavelength is longer than the first common emission peak wavelength.
    • 描述了包括至少一个发光二极管(LED 101)和波长转换器(120)的照明装置(100)。 波长转换器包括支撑板(103)和直接设置在支撑板的表面上的多个第一主体位置(104)和第二主体位置(104)。 多个第一主机站点中的每一个由分散在第一矩阵中的第一矩阵(105)和多个第一量子点(108)组成。 第一量子点具有第一公共发射峰值波长。 多个第二主机站点中的每一个由分散在第二矩阵中的第二矩阵(105)和多个第二量子点(106)组成。 第二量子点具有第二共同发射峰值波长。 第二共同发射峰值波长比第一共同发射峰值波长长。
