whether it is on or off, whether it is at the maximum or reduced level and whether it has any malfunction. As far as the monitoring of the installation is concerned, it will basically be related to the knowledge of the state of the light source, i.e. Control refers to operations related to switching on, switching off and reducing the light level of light sources and always refers to external factors, such as natural light, traffic density or traffic speed. The management of a lighting installation has two functions: control and surveillance. Wherever you have exterior lighting, there will be a need for control. Control systems play an important role in the world of lighting. The transition to efficient lighting technologies (LED) is economically one of the most realistic and simple energy efficiency initiatives. Simply replacing existing lighting systems with other LED technology would reduce energy consumption by up to 40%, and if we also use lighting controls, the figure can reach 80%. Lighting accounts for more than 19% of the world’s electricity consumption. Intelligent lighting, in addition to its control and energy management functions, also contributes to reducing the excess of artificial light to which our cities are subject, making them more livable. Experience shows that it is necessary to work with open systems so that the lighting management system works and communicates with other systems such as air treatment, safety systems, etc. Complete telemanagement systems are currently being developed to meet the needs of different application segments. One of the major drawbacks of these systems is that they do not have flexibility, since they do not allow the individualization of the point of light, and in addition the orders that can emit are of generic character and affect the group, obtaining a rather inaccurate information of the installation. The systems that have been used so far have precedents that date back more than 35 years and allow control and monitoring functions of groups of light points, i.e. The transition to efficient lighting technologies (LEDs) is economically one of the most realistic and simple energy efficiency initiatives. Verification of Voltage drop within the prescribed limit, otherwise select the next standard cable size.Ī distribution board typically has poly-phase branch breakers with the intention of feeding either other sub-panels or large loads and lighting control panel (is also one type of distribution panel) will have mostly single-pole breakers with phase-to-neutral branch circuits feeding lighting circuitry.Lighting accounts for more than 19% of the world’s electricity consumption. Then size of cable from DB to LCP can be determined/sized, rating of the protective devices can be selected and type of CB(s) subject to type of lighting fixtures.Ħ. For Fluorescent light fixtures arrangement of the said fixtures with respect (RYB phases) is necessary to mitigate rendering/glaring and frequency affect.ĥ. To ensure the load balance over the 3 Phase as possible.Ĥ. Adequate utilization/diversity Factor to be applied if applicable (depends on the application).ģ. The final branch circuits to be identified and rating load to be estimated.Ģ. There is the added possibility of having either 'smart' breakers or integral contactors included on the branch circuits to allow for a control means for area lighting beyond local control of an individual fixture/small group of fixtures, such as an office or conference room.ġ. There are a couple of construction differences which may be present, depending on the style of "lighting control panel".įirst, a distribution board typically has poly-phase branch breakers with the intention of feeding either other sub-panels or large loads - such as a motor with a variable frequency drive or other motor controller.Ī lighting control panel will have mostly single-pole breakers with phase-to-neutral branch circuits feeding lighting circuitry.
