4.  Field Glare measurement


4.1. LGM-200B lighting glare measurement system

Glare is one of the main factors that affect the health of light environment. Although the human eye can adapt to the brightness of about 14 orders of magnitude, it will be reduced to 4-5 orders of magnitude when the luminance level of a field is adapted for a period of time, and other objects or light sources above the area will glare.  

The field of view of the human eye is observed at about 30°-120°, that is to say, it is necessary to measure the luminance of the two-dimensional image in the 120° range accurately. Therefore, the fish eye lens is used to collect the image, but the problem of image distortion caused by the fish eye lens is very serious, and the linearity of the ordinary camera is only 3 orders of magnitude, which can not meet the needs of the wide range of the glare measurement. In order to solve these problems, the LGM-2B lighting measurement system introduced by EVERFINE can measure the luminance image of up to 2π full space, which is used for the glare analysis of the field lighting. LGM-2B has high pixel resolution and high angle precision, and the response of the detector is precisely matched with the visual efficiency function of the human eye, and the high precision UGR and TI values can be obtained. It meets the CIE 115, GB/T 5700, GB 50034-2013, JGJ/T163-2008 and other standard requirements.
