The light intensity is equal to the product of the brightness of light energy per unit area and per unit angle of a light source emitting a second in a particular direction. Measurement unit candela intensity in the lounge or candles to symbolize the cd. Ismail is one of the units of the original units.
Measure of exposure to visible light by the human eye works have received. The human eye can only see light in the visible spectrum of light with different wavelengths have different sensitivities. When using the light conditions (poor vision) of the wavelength of 555 nm (yellow-green) is the most sensitive. Radiation intensity at different wavelengths of light that are similar but have a lower light intensity will be. The light curve shows the response of the human eye with lighting function is known. The curve with the symbol V (λ) or exposed based on the average experience of various scientists obtained using different measuring methods. For example, the response to UV light was varied by a factor of ten.
Light intensity should photometry with other units such that the total power received from all directions luminous flux used was wrong. The light intensity can be downloaded from the angle of the space. The light intensity varies with the intensity of radiation, radiation is a physical quantity objective skyscapes for radiometric skyscapes measurements.
Like the other units of the international system, the operational definition Each candle is a candle in a candle light intensity produced by Tvzyhdadn process leading to the definition of Mygrdd- by definition, if a light source with a frequency of 540 terahertz green Tkfam build, and this source of radiation in a particular direction 1/683 watts Steradian, it will emit light in that direction, especially a candle. [1]
Frequency light leads to the definition used in the optical length of 555 nm, which is close to the maximum response of the human eye to light. If you have a source distribution is uniform in all directions, skyscapes the total luminous flux will be approximately 18.40 million (as in Korea is Steradian 4 π). A typical candle light intensity is precisely the whole bottom of a pile.
Before skyscapes defining the candle, the light intensity of the various definitions used in different countries. This definition skyscapes is based on the brightness of the flame of a "standard candle" with a standard combination, or shine a light field with a special skyscapes design. The most famous of these is the Standard English: Tvanshm. [2] Each Tvanshm to light a candle skyscapes by Asprmasty (made from a sperm whale oil) Ykshshm weighing 120 pounds, and the rate of burning grains [3] at the time. Germany, Astralyan, and Scandinavian Hfnr of units used, based on the output of the lamp unit Hfnr. [4] In 1881 AD Zhvlz violet, skyscapes violet as the unit of light intensity suggested that Ismail as the first unit that features a light bulb is particularly notable absence. All the units with the introduction of unit plugs were excluded.
