摘要： Light emitting systems are disclosed. The light emitting system emits an output light that has a first color. The light emitting system includes a first electroluminescent device that emits light at a first wavelength in response to a first signal. The first wavelength is substantially independent of the first signal. The intensity of the emitted first wavelength light is substantially proportional to the first signal. The light emitting system further includes a first luminescent element that includes a second electroluminescent device and a first light converting layer. The second electroluminescent device emits light at a second wavelength in response to a second signal. The first light converting layer includes a semiconductor potential well and converts at least a portion of light at the second wavelength to light at a third wavelength that is longer than the second wavelength. The light emitting system combines light at the first wavelength with light at the third wavelength to form the output light at the first color. When one of the first and second signals changes from about 50% of a maximum rating of the signal to about 100% of the maximum rating, but the ratio of the first signal to the second signal remains substantially unchanged, the first color of the output light remains substantially unchanged.
摘要翻译：公开了发光系统。发光系统发射具有第一颜色的输出光。发光系统包括响应于第一信号发射第一波长的光的第一电致发光器件。第一波长基本上与第一信号无关。所发射的第一波长光的强度基本上与第一信号成比例。发光系统还包括第一发光元件，其包括第二电致发光器件和第一光转换层。第二电致发光器件响应于第二信号发射第二波长的光。第一光转换层包括半导体势阱，并将第二波长的至少一部分光转换成比第二波长长的第三波长的光。发光系统将第一波长的光与第三波长的光组合，以形成第一颜色的输出光。当第一和第二信号中的一个信号从信号的最大额定值的约50％变化到最大额定值的约100％时，但是第一信号与第二信号的比率基本保持不变，输出的第一颜色光线基本保持不变。
