LED激光光谱检测系统BWD-LQ-50X  
   
 
   

       
   
 
   
 
    
 
     产品介绍 目前 LED发展所面临的挑战包含∶ 
    
 
    
 
     1.新型态的LED具备低亮度（<50000 cd/m2）、衰减快的特性  
    
 
    
 
     2.发光半宽（FWHM）较传统 LED小（OLED~100 nm;PVSK LED~50 nm) 
    
 
    
 
     3.非朗伯体（Non-Lambertian）分布，使得辉度（cd/m22 ）换算 EQE 时误差很大 
    
 
    
 
     4.发光波长超过视函数波段（可见光范围），无法以光通量与辉度评价 其中「衰减快」与T红外发光的准确评价」 
    
 
    
 
     ，是与转换效率高低息息相关， 
    
 
    

        
    
 
    
 
     
Product introduction the challenges faced by led development at present include:
 
     
(<50000 cd/m 2）、 Characteristics of fast attenuation
 
     
(oled~100 nm; PVSK led~50 nm)
 
     
, so that the brightness (cd/m 2 2) There is a big error when converting EQE
 
     
-emitting wavelength exceeds the visual function band (visible light range),, "fast attenuation" and "accurate evaluation of t-infrared luminescence"
 
     
, which is most closely related to the conversion efficiency,
