AskWhat is called the lumen, what is flux, what is new lux: Ans1967 France Thirteenth International Conference provides metering to cd , cd / m², lumens, lux , respectively, as the unit of luminous intensity , brightness , flux and other illumination optical unit of measurement used in unified engineering technology has important significance. To enable you to understand and ease of use , the following knowledge will make a brief introduction :1 candlelight , international candle , cd (candela) definition101325 in Newton per square meter standard atmospheric pressure , an area equal to 1 / 60 cm2 absolute "bold" ( i.e., capable of absorbing all of the external light reflected from the object is no ideal ) , pure platinum (Pt) solidification temperature ( about 2042K was 1769 ℃) , the luminous intensity in the vertical direction is 1 candela . Also, the candlelight , the International Candlelight, Candela three concepts are different , not equal . In terms of volume , equal to 58.8 cd 60 international candle , light a candle hefner international candle equals 0.885 or 0.919 candela .A light emitting intensity and brightnessLuminous intensity of light intensity for short , the international unit is candela ( cd ) abbreviated cd. Lcd is the luminous flux emitted by the light source in the specified direction unit solid angle . The radiation source is uniform , the light intensity is I = F / Ω, Ω is the solid angle , in units of steradian (sr), F is the luminous flux , in units of lumens from the light source to the point I = F / 4. The brightness is the brightness of the light emitting surface of the light emitting surface is the ratio of the luminous intensity in a given direction and the direction perpendicular to the light emitting surface of the specified area , the unit is candela / square meter. For a diffuse scattering surface , although the light intensity and the luminous flux in all directions , but the brightness is equal in all directions . TV screen that is similar to the diffuse scattering surface , the image viewed from all directions , have the same sense of brightness .The following is a portion of the light source luminance values : Unit cd / m²Sun: 1.5 * 10 ; Fluorescent : (5-10) * 10 ³; moon ( full moon ): 2.5 * 10 ³; black and white TV screen : about 120 ; color TV screen : 80 or so .3 lumens luminous fluxLight emitted by the light source is radiated in all directions , for a unit time by the area of light, known as the area through which the flux of radiant energy . Different frequencies of light colored eyes are sensitive to different colors of light , even if the colored light energy flux equal, and does not produce the same visual brightness level of the light in the colors yellow , green light aroused maximum brightness sensation . If the green light as standard , making it radiant flux equal to the flux , the shade on the other , the ability to evoke the feeling of a bright light is smaller than the green, the luminous flux is smaller than the energy flux . The unit of luminous flux is the lumen , is a transliteration of the English lumen , abbreviated lm. Absolute blackbody at the solidification temperature of platinum , radiation from the 5.305 * 10 ³ cm ² area out of the flux is 1lm. To show the relationship between light intensity and luminous flux , luminous intensity of 1 candela point light flux emitted per unit solid angle (1 steradian ) within 1 six . The output of a 40W fluorescent lamp luminous flux is about 2100 lumens.4 lux illumination andIllumination available illuminometer measured directly. Illumination unit is lux lux is the English transliteration can also be written as lx. The object is irradiated with uniform light , the area of 1 m2 is obtained by a lumen flux when it is 1 lux illumination . Sometimes, in order to fully utilize the light source in the light source is often an additional reflection means , so that the direction can be more certain of the flux to increase the illumination of the illuminated surface . Such as car headlights , flashlights, photographic lights.The following are the various environmental illuminance values : Unit luxNight 0.001 0.02 ; Moonlight 0.02 - 0.3 ; cloudy indoor :5 -50 ; cloudy outdoor :50 -500 ; sunny indoor :100 -1000 ; illumination under the summer sun at noon : about 10 * 9 th ; the required illumination when reading books :50 -60 ; standard home video camera illumination: 1400 .
AskFuture prospects for OLED lighting: AnsIllumination available illuminometer measured directly. Illumination unit is lux lux is the English transliteration can also be written as lx. The object is irradiated with uniform light , the area of 1 m2 is obtained by a lumen flux when it is 1 lux illumination . Sometimes, in order to fully utilize the light source in the light source is often an additional reflection means , so that the direction can be more certain of the flux to increase the illumination of the illuminated surface .

AskEnergy conservation into two hot spots: AnsThe following are the various environmental illuminance values : Unit luxNight 0.001 0.02 ; Moonlight 0.02 - 0.3 ; cloudy indoor :5 -50 ; cloudy outdoor :50 -500 ; sunny indoor :100 -1000 ; illumination under the summer sun at noon : about 10 * 9 th ; the required illumination when reading books :50 -60 ; standard home video camera illumination: 1400 .
