CIE:The Commissjon internationale de/Eclairage是國際照明委員會的簡稱。

相關(guān)色溫：光源發(fā)射的光與黑體在某一溫度下輻射的光顏色接近，則黑體的溫度就稱為該光源發(fā)射的光的相關(guān)色溫，單位為K。

Related color temperature(CCT): If the color of the light emitted by a light source is closest to that of the light emitted by a black body at a certain temperature, the temperature of the black body is called the related color temperature of the light emitted by the light source, unit is K.

光照強度：是一種物理術(shù)語，指單位面積上所接受可見光的光通量。簡稱照度，單位勒克斯（Lux或lx）。用于指示光照的強弱和物體表面積被照明程度的量。

Light intensity: it’s a physical term ,that refers to the luminous flux of visible light received per unit area. It is called illuminance for short, and its unit is lux(Lux or lx). Used to indicate the intensity of light and the amount of illumination on the surface area of an object.

輻射強度：單位是W/m2，即點輻射源在給定方向上發(fā)射的在單位立體角內(nèi)的輻射通量。

Radiant intensity: the unit is W/m2, that’s the radiant flux emitted by the point radiation source in the given direction within the unit solid angle.

輻射亮度 ：簡稱輻亮度，輻射亮度表示面輻射源上某點在一定方向上的輻射強弱的物理量。指面輻射源在單位時間內(nèi)通過垂直面元法線方向n上單位面積、單位立體角上輻射出的能量，即輻射源在單位投影面積上、單位立體角內(nèi)的輻射通量。

Radiant luminance: abbreviated as radiance, radiant luminance represents the physical quantity of the radiation intensity of a point on a surface radiation source in a certain direction. It refers to the energy radiated by the surface radiation source through the unit area and unit solid angle in the direction “n” of the vertical panel normal in unit time, that is, the radiant flux of the radiation source in the unit projection area and unit solid angle.

輻射照度 (Irradiance)：輻射照度又稱輻照度，是受照面單位面積上的輻射通量，單位：瓦每平方米（W/㎡）

Irradiance: also known as irradiance, it is the radiant flux per unit area of the exposed surface, Unit: watts per square meter (W/㎡)

發(fā)光強度 ：簡稱光強，國際單位是candela（坎德拉）簡寫cd，其他單位有燭光，支光。1cd即1000mcd是指單色光源（頻率540X10^12HZ，波長0.550微米）的光，在給定方向上（該方向上的輻射強度為（1/683）瓦特/球面度））的單位立體角內(nèi)發(fā)出的發(fā)光強度。

Luminous intensity: referred to as light intensity, the international unit is candela, short for “cd”, and other units include candlelight , branch light. 1 cd is 1000 mcd, refers to the luminous intensity emitted by the light of a monochromatic light source (frequency 540X10 ^ 12HZ, wavelength 0.550 μ m) within the unit solid angle in a given direction (the radiant intensity in this direction is (1/683) watts/steradian).

光通量:指人眼所能感覺到的輻射功率，它等于單位時間內(nèi)某一波段的輻射能量和該波段的相對視見率的乘積。

Luminous flux: refers to the radiation power that can be felt by the human eye, which is equal to the product of the radiation energy of a certain band per unit time and the relative visibility of that band.
