GB/T 15043-2008

📋 Scope / 适用范围 ai_extracted

This standard specifies the measurement system and measurement methods for the electrical parameters, total luminous flux, luminous intensity, spatial distribution of luminous intensity, and color temperature (hereinafter referred to as luminous flux, luminous intensity, luminous intensity distribution, and color temperature) of incandescent lamps. This standard applies to incandescent lamps using tungsten as the light-emitting material. This standard does not apply to standard lamps, incandescent lamps with spectrally selective glass bulbs, or incandescent lamps with spectrally selective reflective types.

总光通量 total luminous f1ux φ 光源在4π 空间发射的光通量。单位z 流明(lm) 。 总光通量标准灯 standard lamp of total luminous f1ux 是用于复现和保持总光通量单位 流明(1m) 量值以及用相对法传递量值和测量光源总光通量 的标准量具。

Total Luminous Flux φ The luminous flux emitted by a light source in 4π steradians. Unit: lumen (lm). Standard Lamp of Total Luminous Flux A standard measuring instrument used to reproduce and maintain the magnitude of the unit of total luminous flux, the lumen (lm), as well as to transfer the magnitude through the relative method and measure the total luminous flux of light sources.

发光强度

luminous intensity I 光源在规定的方向立体角上的光通量。单位z 坎德拉(cd) 。 发光强度分布 distribution of luminous intensity l( 仇。) 光源在一系列规定的方向立体角上的发光强度。单位z 坎德拉(cd) 。 颜色温度 color temperature 光源所发射光的色品(光色〉与某一温度下黑体的色品相同，此时黑体的绝对温度就叫做该光源的 颜色温度。简称"色温"。单位z 开尔文(K) 。

luminous intensity I The luminous flux of a light source within a specified solid angle in a given direction. Unit: candela (cd). distribution of luminous intensity I(θ, φ) The luminous intensity of a light source within a series of specified solid angles in given directions. Unit: candela (cd). color temperature The chromaticity (light color) of the light emitted by a light source is identical to that of a blackbody at a certain temperature. The absolute temperature of the blackbody at this time is called the color temperature of the light source. Abbreviated as "color temperature." Unit: kelvin (K).
