![]() ![]() In other words, intensity is the amount of energy that comes in per unit area, per time. The wavelength-weighted power is the measurement of the light source’s power. ![]() Light intensity is the amount of light produced by a particular lamp source. Light intensity can be measured in terms of lm per square meter or lux. It’s a unit of the intensity of a light source. The SI base unit is known as the Candela. The intensity of light is the amount of light that is visible. See also Main Street Lighting What is light intensity? The light will get 25% of the energy if it is moved twice as far away from the plant. The inverse square law states that the intensity of light is determined by the square of the distance from the source. A higher light intensity means there are more packets of light hitting the leaves. Light intensity refers to the amount of energy hitting an area over a period of time. As the distance from a light source increases, the intensity of light is the same as a value. The square of the distance has an effect on the intensity of light.

In LDT photometry files, however, it is usual to specify luminous intensity values in relative to the luminous flux of the lamp. In the output of luminous intensity tables, Evo always displays the luminous intensities listed in the photometric file. Unless it is an absolute photometry with a negative indicator. For example, the luminous intensity table shows a maximum value (range 70°-80°) of 356 cd/klm.However, since EN 13201:2015 requires luminous intensities to be expressed in in relation to luminaire luminous flux, Evo must first convert the luminous intensities from the photometric file: Here, evo displays the luminous intensity table directly in. Luminous intensity value (c,y): 356 cd/klm / 0.65 = 548 cd/klm (356cd/klm is in the photometry file, 548 cd/klm is to be used according to EN 13201:2015 for the light intensity class).However, this value refers to the 13846 lm lamp luminous flux. This result leads to a luminous intensity class of G*3. If we would not carry out the conversion of the luminous intensity values here, the Integral IdOmega over all luminous intensities would no longer give 9000 lm luminaire luminous flux. From the luminous intensity table, for example, a maximum value (range 70°-80°) of 548 cd/klm can be read.The photometry would therefore no longer be correct! Luminaire luminous flux (c,y): 548 cd/klm / 1.00 = 548 cd/klm (548cd/klm is in the photometry file, 548 cd/klm is also to be used according to EN 13201:2015 for the light intensity class).Lamp luminous flux: 9000 lm * 1 = 9000 lm.However, due to the requirement in EN 13201:2015 to refer this luminous intensity value to luminaire luminous flux, we have to carry out the following calculation: As with relative photometry, this value refers to the 9000 lm lamp luminous flux. This result also leads to a luminous intensity class of G*3. ![]()
