The glossary explains technical terms used in lighting industry and special features of ZALUX products.

STANDARDS AND TESTS

ENEC

Is a conformity brand common to luminaires, associated equipments and information technology equipments, that indicates the conformity with European standards. The complying of the norms by the manufacturers is tested by external official bodies (AENOR, VDE…)

CE

A product that is marked with this icon complies with the dispositions of the European Community. Luminaires must comply with 2004/108/EC for Electromagnetic Compatibility, 2006/95/EC for the production of the luminaires and 2009/125/EC for ecodesign

RoHS

The RoHS Directive restricts the use of six hazardous materials in the manufacture of various types of electronic and electrical equipment: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE)

REACH

Comply with the related requirements of European Union Regulation (EC) 1907/2006 concerning the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH)

CB

CB The CB Scheme is an international program for exchange and acceptance of product safety test results among participating laboratories and certification organizations around the world. The CB Scheme offers manufacturers a simplified way of obtaining multiple national safety certifications for their products.

EMC

EMC In order to show the capacity of any equipment or system to work properly in its electromagnetic background without provoking interferences to any other system, we use this symbol certified by VDE

ATEX

European certification given to equipment tested and approved to be intrinsically-safe. If a product / piece of equipment has official ATEX certification, it has been fully tested and approved to be safe to use in hazardous / explosive atmospheres. ATEX approved equipment must show the official 'Ex' logo shown here.

HACCP

They comply with the specifications of foodstuff legislation in accordance with Regulation (EU) No. 852/2004 (HACCP) Appendix II Section I No. 2 a, b Section II No. 1c for luminaires, and can therefore be used in all applications where foodstuffs are processed, handled and packed

Glow wire test

An electrical safety test designed to evaluate the flame resistant properties of plastic materials used in electrical devices. Its purpose is to protect against the risk of fire from overheated or electrically energised parts which may cause the plastic material to ignite.

CE mark

On the market of the european economic area (EU und EFTA countries w/o Switzerland) the products have to be labeled with the CE mark. This mark shows, that the manufacturer ensures to comply with the essential EU directives

D

On luminaires with electronic ballast, we mark with this item when they can be used in places where there is need to limit the external surface temperatures, due to the risk of accumulating combustible dust on the luminaires, but without risk of an atmosphere with risk of an explosion

ELECTRICAL FEATURES

SELV

In compliance with SELV (safety extra-low voltage)

NON-SELV

Not in compliance with SELV (safety extra-low voltage)

Protection classes

IEC 61140 defines 4 classes of protection via earth connection: I. Class 0: This devices have no connection with protective-earth. II. Class 1: All conductive parts of the housing have to be connected to electrical earth. The design of the plag guarantees, that the protective-earth is the first to get connected, and will be the last to be interrupted in a malfunction. III. Class 2: This devices are designed in a way, that they do not need PE-connection, as live parts are separated from housing parts by using reinforced of double insulation. IV. Class 3: The safety extra-low voltage of max. 120VDC or 60VAC for a class 3 device has to be provided by a specialy protected power source or a battery to prevent mains voltage from getting in contact with mains voltage.

LUMINAIRE FEATURES

IK

Protection against humidity and dust.

IP

Protection against impact.

DALI

The abbreviation “DALI” stands for Digital Addressable Lighting Interface. The manufacturer-independent DALI standard, specified in IEC standard 60929, defines a standardized digital ballast interface, which ensures interchangeability and inter-operability of ballasts from various manufacturers. The new standard is not merely a digital interface in addition to the current analogue 1-10 V control technology. Rather, it will gradually replace the latter because of its clear advantages. AG DALI is a working group set up by leading manufacturers and institutions in the field of digital lamp/luminaire control to promote DALI technology and applications.

EX

Explosionproof luminaires, to be used in places where there is an atmosphere with risk of explosion. For further information, please consult the section. These luminaires comply with ATEX certificate.

ET

Electronic transformer

ETDD

Electronic transformer gear dimmable DALI

EB

Emergency battery. (Emergency versions guarantee is limited to 5 years at 35ºC due to the internal operating temperature. Batteries excluded)

The operational temperature under which the luminaire could be installed. Out of this interval, its electronic components could be affected as well as the lifetime of the luminaire Luminaire efficacy Measurement of the amount of useful light output per unit of electricity,and is measured in Lumens per Watt. This is calculated by taking the total lumens released from the fixture by the total wattage consumed by the light fixture.

CRI

In general terms, CRI is a measure of a light source's ability to show object colours "realistically" or "naturally" compared to a familiar reference source, either incandescent light or daylight.

CLO

The light flux of LEDs reduces over time as the diode ages. This light depreciation is more or less linear across the diode’s service life. The luminaire itself can compensate for the light depreciation

HCL

Type of lighting that can benefit the biological, emotional, health, or wellbeing of people. This is achieved by dimming the smart light source, most likely an LED, to mimic the levels of sunlight

650ºC – 850ºC

Results for PC and PMMA for glow wire test.

PIWIS-free

They are 100% PWIS-free thus ensuring a positive use in many applications

ANOTHER CONCEPTS

Gateway

The gateway connects two networks with different protocols and is able to work on any layer of the OSI model of network communication (opposite to a router, that just interfaces on layer 3).

IEC

Abbreviation for “International Electrotechnical Commission”. International standards organisation for electrical and electronic matters. Founded 1906 in London. Current headquarters in Geneve.

Lamp holders

On principle, the application of hot restrike igniters requires lampholders which are particularly devel-oped for that purpose. They are designed to stand a dielectric strength of up to 35 kV and feature special, directly connected cables. In order to avoid arc-overs, they should be mounted onto a heat-resistant, nonconducting base, such as Teflon.

Lamp leads

The high voltage conducting lamp leads have to be appropriate for the supplied high ignition voltage. In most of the cases, single-core high-voltage cables with an electric strength of up to 20 kV in the scope of rated voltage are used in various types. The lamp leads have to be guided separately from mains and control lines. In favour of additional protection against contact, moisture or mechanical damage, the cables can be laid individually, in corrugated pipes, hoses or conduits made of plastic. In order to prevent the occurrence of ionisation, the wires should be fixed with plastic fasteners and installed at a distance from metal parts. Sharp-edged or spiky metal parts close to the lamp wires are to be avoided as arc-overs or corona discharges may as well result around these spots. In the event of distances being too small, materials like Teflon, ceramic and silicone will provide an improved isolation between the parts. One deciding criteria for the choice of the corresponding material is, in addition to the isolation re-sistance, as well the thermal resistance. In case of connections by means of non-insulated conductors and connectors a creepage and clearance distance of approx. 1.5 mm/kV from adjacent potentials, such as reflectors, cable through holes, etc. has to be respected. In the event of symmetric igniters, both wires should be of the same length and laid separated from each other.

Thermical resistance

When we get this indication, we refer to the Glow wire Test, where the thermical resistance of the materials that compose the surface of the luminaries is controlled. If nothing is mentioned, we will understand that the materials will reach the minimum level, 650ºC, indicated by the EN60695-2-11
