luminous intensity

基本解釋

An international unit of luminous intensity per projected area normal to the line of observation.
一個(gè)發(fā)光的強(qiáng)度的國(guó)際單位每計(jì)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(qiáng)度高，具有從紫外到紅外的連續(xù)光譜的點(diǎn)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(cè)試各種LED發(fā)光矩陣每個(gè)發(fā)光元的發(fā)光強(qiáng)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(qiáng)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(qiáng)度大、效率高、體積小、壽命長(zhǎng)等優(yōu)點(diǎn),被認(rèn)為是當(dāng)前最具潛力的光源之一。為了充分發(fā)揮其優(yōu)勢(shì),良好的驅(qū)動(dòng)是不可或缺的。
