CIE:The Commissjon internationale de/Eclairage是国际照明委员会的简称。

相关色温：光源发射的光与黑体在某一温度下辐射的光颜色最接近，则黑体的温度就称为该光源发射的光的相关色温，单位为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.

光照强度：是一种物理术语，指单位面积上所接受可见光的光通量。简称照度，单位勒克斯（Lux或lx）。用于指示光照的强弱和物体表面积被照明程度的量。

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.

辐射强度：单位是W/m2，即点辐射源在给定方向上发射的在单位立体角内的辐射通量。

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.

辐射亮度 ：简称辐亮度，辐射亮度表示面辐射源上某点在一定方向上的辐射强弱的物理量。指面辐射源在单位时间内通过垂直面元法线方向n上单位面积、单位立体角上辐射出的能量，即辐射源在单位投影面积上、单位立体角内的辐射通量。

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.

辐射照度 (Irradiance)：辐射照度又称辐照度，是受照面单位面积上的辐射通量，单位：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/㎡)

发光强度 ：简称光强，国际单位是candela（坎德拉）简写cd，其他单位有烛光，支光。1cd即1000mcd是指单色光源（频率540X10^12HZ，波长0.550微米）的光，在给定方向上（该方向上的辐射强度为（1/683）瓦特/球面度））的单位立体角内发出的发光强度。

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:指人眼所能感觉到的辐射功率，它等于单位时间内某一波段的辐射能量和该波段的相对视见率的乘积。

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.
