    摘要： The present invention relates to an emergency luminaire comprising an emergency lighting unit, non-emergency lighting unit, an energy storage device (5) and a converter device (1,4) configured to provide, via two electric lines (3), a first supply voltage to the lighting units using energy stored in the energy storage device (5) and to provide, via the two electric lines (3), a second supply voltage to the lighting units using mains supply. The converter device (1, 4) determines whether or not the mains supply fails and provides the first supply voltage when the mains supply fails, wherein the non-emergency lighting unit determines whether the first supply voltage is provided and deactivates its light source when the first supply voltage is provided.

    摘要： The invention relates to a process for increasing the recharging efficiency of an energy storage system when, said energy is withdrawn from the public and/or national electricity grid and is used to recharge, in advance with respect to when it will be subsequently used, one or more accumulators and/or storage systems (20) present in an electrical system, where the process is implemented by means of a computerized system acting on an inverter for managing the accumulators and/or storage systems, wherein said computerized system comprises at least one memory storage unit and at least one control unit configured to perform at least the following steps
    - a) monitoring the state of charge of one or more accumulators and/or storage systems (20) and the energy exchanged by them with the inverter (30) and/or the plant (10,15,100) during the charge/discharge phases over a time span;
    - b) monitoring the consumption profile of a user of the above-mentioned installation (10,15,100) over a time span;
    - c) monitoring the energy withdrawal profile from the public and/or national electricity grid of a user over a time span in the context of this installation (10,15,100);
    - d) estimation of the user's and/or plant's subsequent consumption and/or withdrawal profile (10,15,100) over a time span subsequent to a point in time of observation;
    - (e) analysis of changes in the price of electricity related to market developments and estimation, with respect to a point in time of observation, of the possible trend of the price of electricity over a time span following that point in time of observation;
    - (f) storage, management and aggregation of the data collected in phases (a) to (e) both in real time, namely at a given instant, and in an aggregate and/or statistical manner over time;
    and, on the basis of said data obtained from said monitoring and estimates, determination of the next most appropriate instant (TS) with respect to the time of observation for generating a command to start the recharging process of the accumulators and/or the storage systems (20) in the time period corresponding to the lowest values of the estimated price of energy wherein said recharging process is terminated at a later time (TE) upon reaching a predetermined amount of energy (STARGET) - from time to time calculated by means of said estimates - to be preemptively stored in the accumulators and/or in the storage systems (20) with the aim of making available, in said systems and where indispensable, the energy required for subsequent consumption by withdrawing it in advance, prior to its use, from the public and/or national electricity grid at the lowest possible estimated purchase price.
