通过研究不同色温(CT)黑体辐射光源对于暖色物体以及冷色物体作用后的有效反射亮度,以及不同主波长(DW)高斯分布光源对一定主波长物体的有效反射亮度,得到不同光源色温、主波长对于物体有效反射亮度的影响规律,并用于多芯片发光二极管(LED)光谱合成。结果表明,一般情况下,光源色温与物体色温匹配时,相应有效反射亮度更高,而光源主波长与物体主波长相适应时,有效反射亮度也会更高。多芯片LED合成中,相匹配物体主波长芯片能够得到相对更高的有效反射亮度,是提升有效效率的主要因素,同时也要考虑光源光色效果。单芯片纯度高的RGB芯片合成LED对于特定物体色样更容易得到高的亮度反射率,而WRB芯片合成LED,由于白光芯片纯度低,合成LED对于各色样反射率稳定性更好。
By studying the effective reflection brightness of different color temperature (CT) blackbody radiation sources on the warm objects and cool objects, and the effective reflection brightness of certain dominant wavelength objects by different dominant wavelength (DW) Gaussian distribution light sources, the color temperature, dominant wavelength The law of the effective reflection of the object brightness, and for multi-chip light-emitting diode (LED) spectral synthesis. The results show that under normal conditions, the corresponding effective reflection brightness is higher when the color temperature of the light source is matched with the color temperature of the object, and the effective reflection brightness is higher when the main wavelength of the light source is matched with the dominant wavelength of the object. Multi-chip LED synthesis, matching the main wavelength chip can get a relatively higher effective reflection brightness is to enhance the effective efficiency of the main factors, but also to consider the light source color effects. Single Chip High Purity RGB Chip Synthesis LEDs are more likely to achieve high brightness reflectance for specific object color swatches, while WRB chips synthesize LEDs. Synthetic LEDs have better reflectance for each color sample due to the lower purity of the white chips.
