Zhongshan engineering lamp customization factory: Design of engineering lighting lamp brightness on glare

2022-04-08 548

At present, engineering lighting lamps are widely used in indoor lighting lamps. Especially with the implementation of LED lighting skills, energy-saving engineering lamps are more and more liked by people. The brightness can be said to be an important factor of engineering lamps. Let's analyze the influence of the brightness of engineering lamps of Zhongshan engineering lamps customization factory on glare.

Compared with traditional fluorescent lamps and energy-saving lamps, the surface brightness of engineering lighting lamps is higher, so the restriction on glare is more important. UGR index is the common glare index, which is generally used as the evaluation parameter of indoor glare, as follows:

LB indicates the background brightness, in CD / m2; L indicates the brightness of the lamp, in CD / m2; ω Indicates the solid angle formed by the luminous part of the engineering lamp to the observer, in SR; P is the position index of each individual engineering lamp.

The common glare index UGR is related to the influence of the scale of engineering lighting lamps, the surface brightness of lamps and the normal completion range of lamps. In the process of calculating UGR value, the main evaluation method can also be used.

After cleaning the influence of color temperature and color rendering index, the general led glare control requirements are higher. If only using the glare control method of traditional lamps and lanterns, it is often difficult to meet the requirements, because the surface brightness of LED engineering lamps and lanterns is high, so the glare control is very important for the application of engineering lamps and lanterns.

Glare control is the focus that people will pay attention to when choosing engineering lighting lamps. Glare control also has a direct impact on the lighting environment and lighting quality. We should master it when using engineering lamps.
