luminous flux 【物理學】光束,光通量。

luminous intensity

With green lighting project implementation , high - intensity gas discharge lights with high luminous flux , high optical efficiency , long life and good hin color characteristics are widely applied . particularly the metal halide light have the aforementioned advantages , so it is known as the ideal light source 隨著綠色照明工程的實施,高強度氣體放電燈以其高光通量、高光效、長壽命和顯色性好等特點得到了廣泛的應用,特別是金屬鹵化物燈同時具備上述優點而被稱為最理想的光源。

Photometric and colorimetric measurement , such as luminous flux measurement of all kinds of lamps , luminous density measurement in classrooms and color measure of color tv etc . are commonly used in daily manufacturing . at present , special photometric and colorimetric instruments are available 在日常的生產中,光度和色度的測量是很常見的,如各種燈的光通量測量,教室內照度測量,彩色電視機的顏色測量等等。

Lighting by means of luminaires with a light distribution such that not more than 10 per cent of the emitted luminous flux reaches the working plane direct , assuming that this plane is unbounded 采用具有一定配光曲線的燈具進行照明,在不考慮工作面邊界時使得直接到達工作面的光通不超過總光通的10 %的照明方式。

The second chapter briefs the fundamental principles and methods of photometric and colorimetric measurement , including the measurement principia of luminous density , luminous flux , luminance and chrominance 第二章闡述了光度和色度測量的基本原理,測量的方法及其儀器的工作原理。

Lighting by means of luminaires with a light distribution such that 90 to 100 per cent of the emitted luminous flux reaches the working plane direct , assuming that this plane is unbounded 在假定為面積無限大的平面上,有90 %至100 %的輻射光通以直射的方式到達該平面的照明方式。

The inability of materials to reflect or transmit light . the parameter is the degree of absorption , defined as the ratio of absorbed to incident luminous flux 燈光設計師所說: “人類環境設計,對人類感官體驗設計同樣有效,所有的視覺設計實際上都是燈光設計。 ”

Different color and viewing angle are available according to your requirement ! good luminous flux and high luminous intensity , long lifespan , good quality and competitive price 有各種不同的顏色和角度選擇,發光強度高,光能量大,質量一等,價格優惠。

Abstract : the self2absorption of optical source is introduced when measuring leds luminous flux with integrating spheres , and two correction methods is recommended 摘要:介紹了積分球測量中光源體的自吸收效應,提出了兩種校正方法。

It is helpful to reducing the uncertainty of measuring leds luminous flux with integrating spheres 自吸收效應的校正有助于降低用積分球測量光通量的不確定度。

Of a source . the luminous flux emitted above [ below ] a horizontal plane passing through the source 對光源而言。高于[低于]通過光源的水平面而發射的光通量。

The ratio of luminous flux at a specific wavelength to the radiant flux at the same wavelength 發光效率一定波長的光量對同樣波長的輻射光量的比例

They create a uniform value of luminous flux due to the high frequency used 由于使用高頻,電子鎮流器產生均勻的光通值。
