The ceilings of industrial workshop with large-scale machinery are very high, so they adopt a combined lighting method of high light effect LVD induction lamps and lamps with good condensation. Considering the ceiling height and design illumination, it is necessary to choose dimming lamps. In case that the installation height is over 10 meters, it’s better to use combination lighting of high bays and flood light so as to achieve a better work surface lighting effect.
As for the medium height ceiling at the height of about six to ten meters, it should adopt medium and wide lighting dimming lamps. It can save energy by using the special induction lamp with long use term and highly frequent operation.
Using LVD lamp lighting system
Annual savings of energy consumption of 563,096 kWh annual electricity savings 465,016 yuan, saving energy consumption by70.7%., saving power rate by 71.6%.
