luminous intensity

基本解釋

An international unit of luminous intensity per projected area normal to the line of observation.
一個發(fā)光的強度的國際單位每計畫的地區(qū)與觀察的線垂直。
The short arc Xenon lamp is a sort of point source having very high luminous intensity and a continuous spectrum from ultraviolet to IR.
短弧氙燈是一種發(fā)光強度高，具有從紫外到紅外的連續(xù)光譜的點光源。
It can be used to measure the luminous intensity, forward voltage, reverse current of each luminous dot in all kinds of LED luminous dot matrix.
能測試各種LED發(fā)光矩陣每個發(fā)光元的發(fā)光強度，正向壓降和反向電流。

a measure of the amount of light that a point source radiates in a given direction. It is expressed by the luminous flux leaving the source in that direction per unit of solid angle ( symbol: )

發(fā)光強度
As one of the most promising light sources, White LED has many advantages, such as high luminous efficiency, high luminous intensity, long life period etc.
白光LED具有發(fā)光強度大、效率高、體積小、壽命長等優(yōu)點,被認為是當前最具潛力的光源之一。為了充分發(fā)揮其優(yōu)勢,良好的驅(qū)動是不可或缺的。
