积分球工作原——厂家工程师结合图解给大家解析

发布者:admin 发布日期:2019-01-23

  对于很多朋友积分球的原理还不是特别清楚。今天积分球厂家的李工程师就从原理方面介绍一下积分球的原理和适用的范围。积分球是一个内壁涂有白色漫反射材料的空腔球体,又称光度球,光通球等。 球壁上开一个或几个窗孔,用作进光孔和放置光接收器件的接收孔。

  The principle of integrating sphere for a lot of friends is not particularly clear small make up today is to introduce the principle of integrating sphere from the aspects of principle and applicable scope of integrating sphere is a wall painted with white diffuse material cavity of the ball, also known as luminosity, optic ball QiuBi on one or a few Windows open hole, used as a light into the receiving hole hole and put the light receiving device

  

  积分球又称为光通球,广泛应用于光度、色度及辐射度计量测试场合。 是一个中空的完整球壳。内壁涂白色漫反射层,且球内壁各点漫射均匀。光源S在球壁上任意一点B上产生的光照度是由多次反射光产生的光照度叠加而成的。由积分学原理可得,球面上任意一点B的光照度E为:

  Integrating sphere diameter size: 1.0 m, 1.5 m, 1.75 m, 2.0 m, 2.5 m, 3.0 m scope of incandescent light bulbs, LED energy-saving lamps cold cathode fluorescent annular fluorescent lamp tungsten halogen lamp and straight shape straight shape fluorescent lamps HID lamp light source such as integrating sphere light electric test principle of integral ball is also called optic, widely used Yu Guangdu chromaticity and radiation measurement occasions is a complete hollow spherical shell wall painted white diffuse layer, and the ball inside each point diffuse homogeneous The illuminance generated by the light source S at any point B on the spherical wall is the result of the superposition of the illuminance generated by multiple reflections. According to the principle of integration, the illuminance E of any point B on the spherical surface is

  积分球的内壁应是良好的球面,通常要求它相对于理想球面的偏差应不大于内径的0.2%。球内壁上涂以理想的漫反射材料,也就是漫反射系数接近于1的材料。常用的材料是氧化镁或硫酸钡,将它和胶质粘合剂混合均匀后,喷涂在内壁上。氧化镁涂层在可见光谱范围内的光谱反射比都在99%以上,这样,进入积分球的光经过内壁涂层多次反射,在内壁上形成均匀照度。为获得较高的测量准确度,积分球的开孔比应尽可能小。开孔比定义为积分球开孔处的球面积与整个球内壁面积之比。

  Integrating sphere wall should be a good spherical, usually require it relative to the ideal of the spherical inner diameter deviation should be no greater than 0.2% of the ball on the inner wall coated with ideal diffuse material, which is diffuse reflectance close to 1 material commonly used is magnesium oxide or barium sulfate, it evenly mixed with gelatin binder, spraying, the walls of magnesia coating in the visible spectrum range of spectral reflectance were over 99%, in this way, the multiple reflection through inner wall coating of light entering the integrating sphere, the scattering form uniform illumination in order to obtain higher measurement accuracy, integral ball opening ratio should be as small as possible The hole ratio is defined as the ratio of the area of the ball at the hole opening to the area of the whole inner wall of the ball

  积分球又称为光通球,广泛应用于光度、色度及辐射度计量测试场合。 是一个中空的完整球壳。内壁涂白色漫反射层,且球内壁各点漫射均匀。光源S在球壁上任意一点B上产生的光照度是由多次反射光产生的光照度叠加而成的。由积分学原理可得,球面上任意一点B的光照度E为:

  公式(1)中,E1为光源S直接照在B点上的光照度,E1的大小不仅与B点的位置有关,也与光源在球内的位置有关。如果在光源S和B点间放一挡屏,挡去直接射向B点的光,则E1=0,因而在B点的光照度为:

  In formula (1),E1 is the illumination of the light source S directly on point B. The magnitude of E1 is related to not only the position of point B, but also the position of the light source in the sphere.

  公式(2)中,r为积分球半径、ρ为积分球内壁反射率。r和ρ均为常数,因此在球壁上任意位置的光照度E(挡去直接光照后)与灯的光通量Φ成正比。通过测量球壁窗口上的光照度E,就可求出光源的光通量Φ。

  Formula (2), r the sphere for integral rho for integrating sphere wall reflectance r and rho are constant, therefore, any position in the QiuBi illuminance E (block to direct sunlight) is proportional to the lamp luminous flux Φ by measuring QiuBi window light E, can calculate the flux Φ light source
