  • Characterisation of CSS supplied emergency lighting equipment Charachterization of most common emergency lighting sources behaviour in terms of inrush current.

    Scope of this paper is to report results of an experimental research aiming to characterize emergency lighting equipment behavior during switch on transients with static CSS supply. Emergency lighting equipment inrush current peak values and waveforms are typically very dispersed depending on technology and manufacturers and can create problems when sizing or operating CSS equipments. High peak values can lead to CSS electronic protection tripping. Emergency lighting centralized systems are nowadays becoming a growing issue due to higher safety level requirements in addition to higher lighting power needed. Considering the lack of available reliable data on lighting equipment behavior, inrush current issue is currently approached by CSS over sizing. The research aims to fill this gap providing statistical data obtained with a proper scientific approach. Given the importance of CSS cost, the availability of such data will allow system designers to optimize CSS sizing, reducing both operative (maintenance and losses) and installation costs. The key factor for an optimal CSS sizing is the knowledge of the behavior of lighting equipments during switch on phase: the cool start phase is typically considered the most critical condition.Measurements described in this paper have been carried out on different types of lamps typically used in emergency installations around Europe mains supplied. Further investigations have been done with sample lamps CSS supplied. Network supply conditions have been chosen in order to evaluate the parameters describing phenomenon in terms of duration, maximum peak value and current rms value during turn on transients. CSS supply conditions have been chosen in order to evaluate lighting equipment behavior with current limitation and non sinusoidal waveform.

    Nowadays, Permanent Emergency Lighting Systems (PELSs) are widely used in many applications, including emergency exit indication and lighting in critical or strategic points. Limitation in operation hours in classical lamps (10 000-20 000 h for fluorescent lamps) implies short lamp replacement times and, therefore, high maintenance costs. This paper shows an alternative solution based on high-efficiency LEDs. The long operation life (above 100 000 h) of high-efficiency LEDs with a very simple electronics circuitry implies an interesting solution for these types of applications. A 30-lm and 1-h PELS has been built and tested. A low-cost power supply has been built and used as a battery charger and LED driver.

  • Evaluation of a high efficiency boost stage to supply a permanent LED emergency lighting system

    The first LED diode was made around 1962 (red LED by Holonyank & Bevacqua). These initial LEDs and posterior developments are widely used in very-low lighting level applications. Ternary and quaternary alloys are the bases of the present high-brightness LED's. Currently power LEDs are used in low-medium lighting applications: for instance, permanent emergency lighting systems (PELS), traffic lights, emergency exit indications, lighting in critical or strategic points, i.e. the limited lamp life in classical lamps 10.000-20.000 hours for fluorescent lamps implies short lamp-replacement times and, therefore, high maintenance costs. To overcome this situation a boost converter to supply a PELS system based in LED was developed. The topology and proposed control assure a constant current through LEDs for all the battery conditions. The long operation life (above 100.000 hours) of high efficiency LED's and a very simple electronics circuitry implies an interesting solution for this type of applications. Finally, a 30 lumens and 1 hour PELS has been built and tested.

  • Emergency lighting system integrated into a compact high-brightness LED lamp

    This paper presents an emergency lighting system integrated into a compact lamp using high-brightness LEDs. These devices have high luminous efficacy, long useful life, small size and they are resistant to vibrations. Besides, they are supplied with low voltage and current values and they do not need ignition process. These features make these devices attractive to use in emergency lighting. The proposed circuit is simple and has low cost. Its main characteristic is the easiness of installation simply replacing incandescent and compact fluorescent lamps with a LED lamp. The proposed circuit supplies the LEDs in two ways. First, by mains (220 V<sub>AC</sub>) using a circuit called voltage regulator in DC. Another way, in the emergency mode, the circuit supplies the LED using a Ni-MH battery without the need of converter. The Brazilian standard (NBR 10898) and IEEE standard (IEEE Std 446-1995) for emergency lighting systems are attended by the topology. The complete circuit was simulated and the results show a satisfactory behavior of the lamp.

  • A compact single-stage converter for emergency lighting applications

    This paper presents a compact single-stage converter for emergency lighting applications. The converter is derived by integrating a bi-directional flyback converter and a half-bridge series-resonant parallel-loaded inverter, which can fulfill the functions of battery charging, discharging and lamp ballasting. Unlike conventional approaches, the rectified and filtered input voltage is directly added on the battery voltage in the proposed system, which can simplify the circuit configuration. Derivation and operating principle of the proposed converter is first presented and an application to emergency lighting is then developed. Hardware measurements have verified its feasibility. The proposed single-stage converter has the unique features of simple configuration, ease in combining with the existing lighting fixture and dimming capability, and it can be readily further integrated with a boost or a buck-boost converter to achieve power factor correction.
