Minimalist emergency luminaire, energy efficiency and avant-garde design

Primarily, you will need the floor plan of the enclosure to be studied in DXF format. As complementary information, it is advisable to have a plan of sections, conventional lighting, fire protection elements and evacuation routes.

Yes, if you need Luznor to carry out the lighting calculation, you can contact the sales department, who will not only provide you with the economic offer of the products resulting from the lighting study, but will also provide you with a complete report as a technical offer. 

The lighting calculation service and delivery of the report is free of charge. 

The data to be included in the calculation report are eligible by the user of the PCI software.

By accessing the “Datos a imprimir” section of the “Proyecto” submenu, you can decide whether to include one or all of the following aspects: Características del recinto (Enclosure characteristics) and resumen del cálculo (calculation summary), Vista en planta (Plan view), Posiciones de las luminarias (Luminaire positions), Iluminancias en recinto (Enclosure illuminances), Diagramas isolux (Isolux diagrams), Niveles de grises (Grey levels), Recorridos de evacuación (Evacuation paths) and Puntos de control (Control points).

A file with an LDT extension is a file type that stores the lighting parameters of a luminaire such as its size, the number of lamps in the luminaire, its luminous flux, etc.

This file allows lighting calculations to be made with Luznor luminaires using Dialux software. The LDT files of all Luznor emergency lighting devices are available on this website for free download and use.

Yes, the BC3 files for Luznor emergency lighting devices can be downloaded from this website as well as from the ACAE website.

The REBT establishes the technical conditions and guarantees to be met by low voltage electrical installations, i.e. with a voltage of less than 1,500 Vd.c or 1,000 Va.c.

It applies both to new installations and to installations existing before its entry into force that are subject to major modifications or when their state, situation or characteristics imply a serious risk to people or property. It is mandatory and is divided into a formal part (articles) and a technical part made up of 52 Complementary Technical Instructions (ITC).

This information on the REBT and other applicable regulations is available in Luznor's Emergency Lighting Regulations and Application Guide. If you need additional information, please do not hesitate to contact Luznor.

The ITC-BT-28 defines when a premises is defined as a place of public concurrence. In summary, public premises can be grouped by type:

  • Entertainment and recreational activities: cinemas, theatres, stadiums, sports halls, bullrings, amusement parks, fairs, party halls, etc.
  • Meeting, work and health facilities: churches, conference and congress halls, bars, restaurants, museums, hotels, common areas of shopping centres, airports, passenger stations, car parks, educational establishments, libraries, student residences, gyms, offices with a public presence, hospitals, doctors' offices, etc.
  • Depending on the difficulty of evacuation of any premises: high-rise buildings, basements, large warehouses, etc.
  • Other premises: any premises with an occupancy capacity of more than 100 persons.

Likewise, the ITC-BT-28 indicates the obligation to have an emergency lighting system in each case. It is advisable to consult it or, alternatively, to consult the Luznor Emergency Lighting Regulations and Application Guide, available on this website.

Emergency lighting equipment must bear a marking intended to indicate its type, mode of operation, incorporated devices and rated life.

This marking must be clearly visible on the devices and must consist of a rectangle divided into four cells, each of which contains one or more positions to be filled in with figures or letters.

This lighting is intended to ensure, in the event of a power failure in the normal lighting supply, the illumination of the premises and accesses up to the exits, for possible evacuation of the public or to illuminate other indicated points.

Emergency lighting includes safety lighting, which ensures illumination during the evacuation of an area, and replacement lighting, which must enable work to be completed safely. Safety lighting can also be divided into evacuation lighting, ambient or panic lighting and high-risk area lighting.

The requirements are different for each type of emergency lighting mentioned. In addition, the REBT requires emergency lighting to be installed in certain specific locations, both with safety lighting and replacement lighting.

At the product level, the REBT covers two types of emergency lighting devices:

  • Self-contained luminaires: are luminaires providing maintained or non-maintained lighting and are characterised by the fact that the battery, the lamp, the control gear and the verification and control devices, if any, are contained within the luminaire or at a distance of less than 1 m from the luminaire.
  • Central source-powered luminaires: are luminaires that provide maintained or non-maintained lighting and are powered from a central supply system, i.e. not incorporated in the luminaire.  

The main advantages of centralized devices over self-contained devices are the simplicity of battery maintenance and the safety of the operator working at lower voltage levels. However, centralized devices have the major disadvantage that if the central source fails or the cable feeding the devices is cut or burns out, none of them will be operational. For this reason, the REBT includes more stringent installation measures for centralized devices.

Yes, Luznor makes the Luznor PCI software available to any user of the website to carry out the relevant lighting studies.
