False-ceiling/recessed luminaire compatibility

Electrotechnics 

Fluorescent discharge lamps 

Electrical system should be sized according to apparent power “A” (equal to the product of supply voltage by the absorbed power). With some equipment (incandescent 

lamps, resistance furnaces, etc.) all absorbed apparent power is used as active power “P”, with others (fluorescent lamps, motors, transformers, etc.), part of the absorbed 

apparent power, indicated as reactive power “Q”, is used to excite the magnetic circuits. Consequently it cannot be used as active power to perform the work. 

The ratio of active power to apparent power represent the power factor “cosϕ” (to be read as “cos fi”), i.e. the discrepancy between voltage and current when the equipment 

absorbs reactive power. 

cosϕ = ___ P 

A 

Companies supplying electric energy foresee increased fees for users with a low power factor. This is why it is required that all system are power-improved to a cosϕ >0,9

Electronic ballasts for fluorescent lamps 

• Average energy saving equal to 25% 

• Immediate lighting, simultaneous in case of several lamps, without any noise 

• Low temperature switch on 

• In low temperatures, higher luminous flux that can be obtained with conventional 

system (in some cases also 100%) 

• Buzz- free operation 

• No flickering effect 

• No lamp end blackening 

• No stroboscopic effect 

• No radio noise and very small magnetic fields 

• Low operating temperatures with reduced thermal load on the system 

• Non-pulsing “continuous” light as in the traditional 50Hz type, and therefore 

“not tiring”. 

• Low sensitivity to mains voltage surges 

• High power factor (cosϕ) 

• Light control option in the dimmer version 

• Selection of “dc” or “ac” versions 

• Automatic shut-off at lamp exhaustion and automatic reset after replacement 

Electronical ballasts with dimmers 

for fluorescent lamps 

Ballasts with dimmers for fluorescent lamps Ballasts with dimmers not only offer 

the typical advantages of electronic ballasts as mentioned above, but also 

the possibility of adjusting the light flow emitted by the lamps from 1% to 

100% depending on the lamps and models. 

We recommend, whenever possible, to use the less expensive odels with a limited 

adjustment range (from 10-20% to 100%). 

This type of adjustment range allows to significantly increase the system’s 

energy saving, difficult to quantify since it depends on several 

factors, such as: 

• geographical position 

• room orientation and position 

• glass panel size and type 

• reflection factors in environment 

• cleanliness of glass surfaces 

Depending on the model, adjustment takes place by means of: 

• a continuous voltage which may vary from 0 to 10 Vc.c 

• a digital signal 

• management system (EIB, LON, DALI) 

DALI SYSTEM 

DALI is the new digital interface standard for electronic ballasts with dimmers 

and describes the communication protocol with the electronic ballasts, but not 

the control systems. DALI is not a bus system, but the definition of a new interface! 

EIB (European Installation Bus) and LON (Local Operating Network) are 

systems which completely cover all the necessary functions to manage a building. 

These technologies not only allow to control lighting, but also heating 

and air conditioning systems as well as safety systems. DALI (Digital Addressable 

Lighting Interface) is designed to manage the light of an environment to 

be lit, but, if necessary, it may also be incorporated into the management 

systems of building of a superior level through the EIB and LON interfaces. 

Developed both to control light scenarios and to be interfaced with building 

management, DALI offers a very flexible sophisticated light control system at 

low installation costs. 

DALI’s crux is the on/off and adjustment combination through the control connections 

with the possibility of controlling each single ballast. This allows to independently 

control lighting equipment belonging to a single control circuit by 

re-configuring the installation without modifying the system. 

Main advantages: 

• The polarity of the control lines is irrelevant for electronic ballasts. 

• It is possible to use the existing wiring both for the power supply and for the control 

lines. 

• Digital technology ensures communication without any interference. 

• The lighting and adjustment circuits are independent from the wiring layout and 

thus offer a high flexibility; the control connection is low voltage without polarity 

in order to eliminate any wiring error. 

• It is possible to control single or groups of lighting devices. 

• During the design stage, it is not necessary to worry about combining lighting devices 

with relative switches, control panels, sensors, etc. This type of combining 

may occur at a later time and may be modified at any time without any modification 

to wiring. 

• It is possible to add on new sensors and new interfaces without having to modify 

the wiring of the lighting devices, all one has to do is to select the devices to be 

controlled and re-program the system. 

• DALI electronic ballasts may belong to more than one group at the same time. 

• The values attributed to lighting scenarios and group assignment may be memorized 

in the electronic ballasts (needs a definitely lower number of components than 

that required by a 1-10 Vc.c. system). 

• The feedback from the electronic ballast helps to identify: operating conditions, 

light on/off, current value of light output, lamp not working. 

• It is possible to foresee special settings to define the speed to change lighting levels 

or behavior in case of a system malfunction. 

• When a scenario is recalled, all the DALI electronic ballasts automatically position 

themselves to the set values. 

• Different lighting scenarios for different visual tasks or to create different “environments” 

may be memorized in the electronic ballasts. 

• Adjustment from 1 to 100% (depending on the type of electronic ballast)

The greater number of luminaires with electronic ballasts compensates for the lower light flux 

emitted (5000 lm vs. 5200 lm) from the lamps with this type of ballast.

Emergency lighting 

1.1 Generalities 

Emergency lighting is intended for operation when standard lighting fails (UNI EN 

1838 Lighting engineering application - Lighting emergency) and it is divided into the 

following types: 

• Back up lighting that, in case of failure of standard light sources, should allow to go 

on or, where possible, achieve a work cycle in progress under safety conditions. 

• Safety lighting that, in case of accidental lack standard light sources, should be provided 

to identify escape routes and guide through them also under extremely critical 

conditions 

• In turn divided into: 

– Lighting of escape routes 

– Anti-panic lighting 

– Lighting of high risk activities 

1.2 Installation 

The safety system must be independent of any other electrical system on the premises 

1.3 Intervention 

The automatic intervention time for safety lighting goes from the moment that the ordinary 

lighting power system fails and the moment in which safety sources are enabled. 

Regulations identify automatic intervention safety power supply in five different 

categories, depending on the time required for them to become available: 

1) Continuity power supply, thanks to which the lighting devices remain fed and therefore 

permanently lit, that is to say without a break. 

2) Power supply with a very brief interruption, no higher than 0.15 s 

3) Power supply with a brief interruption, higher than 0.15 s but not higher than 0.5 s, 

4) Power supply with a medium interruption, higher than 0.5 s but not higher than 15 

s 

5) Power supply with a long interruption, higher than 15 s. 

The choice of the type of interruption must be made according to how the premises 

are to used, that is to say in compliance with the requirements of legislative texts or 

specific technical regulations. 

A typical example of safety lighting devices which always remain lit is that of cinemas 

and theatres, where lighting, of escape routes outside the auditorium and safety lighting 

inside the auditorium, is permanent. 

Regulation UNI EN 1838 requires that along escape routes, light sources must reach at 

least 50% of their light performance within 5 s and 100% within 60 seconds. 

1.4 Autonomy 

Devices may be generally supplied with emergency groups with an autonomy of 1 or 3 

hours. 

The choice of the autonomy of a safety lighting system, unless otherwise specified by 

regulations (CEI 64-4, CEI 64-8, CEI 64-50, etc.) or legislation (Legislative Decrees, 

Ministerial Decrees, etc.), must be in relation to the time required to evacuate the premises, 

while for a back up system, the choice depends on the time needed to end a 

work cycle. 

All batteries, either Lead or NiCd, suffer from a progressive loss of power during their 

life. 

This loss can be accelerated in case of long storage or operation in high 

temperature. 

Autonomous emergency luminaries must be fitted with batteries that need not to be

par.22.6.8). 

Battery replacements required when the luminaire does no longer meet declared duration 

performance. 

1.5 Recharging 

• 6 h for premises used for medical purposes autonomy must be guaranteed after 6 h 

(cei 64-4 par. 4.1.01) 

• 12 h –for schools 

– for private and public entertainment premises 

– for tourist-hotel activities 

• 24 h whenever not differently required (CEI EN 60 598 2-22.1:1999-04 par. 22.19.1) 

The emergency groups supplied by NORLIGHT S.p.A. are intended for a 24h recharge. 

A 12h recharge is possible by using the groups with a 3 hour autonomy as if they had 

a 1h autonomy (in 12 h the batteries are charged at 50%, but since they are expected 

to last 3h, they can ensure the expected 1 hour autonomy). 

No emergency group is available with a 3h autonomy to be recharged in 12h. 

1.6 Maintenance 

• First installation inspections 

– Operation (turning on or off in case of a power failure through controls, if present) 

– Lighting level 

– Autonomy 

– Line independence 

– Equipment positioning 

– Inhibition controls (if present) 

• Periodical inspections 

– every time the premises are opened (only for public premises); operation of the 

emergency system 

– every six months: check operation of the emergency system and the autonomy 

– every 4 years: 

a) check operation of the emergency system, autonomy, lighting level 

b) replace batteries. 

1.7 Lighting 

The chart on the page here above indicates the light values and autonomy of emergency 

systems required by legislation or by regulations for various types of premises. 

It is important to point out that emergency lighting should not be bound to fixed values, 

but should also consider the light values during normal operation, since the eye 

requires a longer time to adjust to big differences, and could therefore be a cause of 

panic.

Chemical Resistance Table 

This table shows the resistance to chemicals of materials generally used. Data is referred 

to an ambient temperature of approximately 22°C. Some of the industrial environments 

where corrosion is likely to take place are: 

- Chemical and oil plants 

- Food plants (dairies, butcheries, breweries, etc.) 

- Chemical laboratories 

- Agriculture 

- Collectivity kitchens 

- Painting plants 

- Plants and workshops with mineral oil vapours 

- Tinning plants 

and so on. 

Shock resistance: IK code (CEI EN 50 102) 

The IK code is followed by a numeric group which identifies the value of the shock 

energy (see chart) that the casing must withstand for 5 consecutive impacts, but for 

no more than 3 times in the same place, unless differently specified. 

The test equipment may work according to 3 principles: 

• spring hammer: weight pushed by a calibrated spring; 

• pendulum hammer: weight hinged on a rotation axis through an arm which controls 

its path; 

• vertical hammer: weight which falls freely on the test surface without bouncing 

and from a specific height 

The shock element consists in a steel body and an insert destined to the shock with 

the object to be tested.

Flame test 

Regulation CEI EN 60 598-1 (Par. 13.3.1) 

Materials to which it is applied 

The parts of insulating material (excluding ceramic) which keep the power carrying 

parts in position must be subjected to the needle flame test. 

Test conditions (Publication IEC 695-2-2) 

• The test sample must be subjected to the flame in the area where high temperatures 

are most likely. 

• Duration of the test: 10 s 

• Sheet of paper, specified in 6.86 of ISO 4046 regulation, laid down horizontally 

200 mm under the test sample. 

Result of the tests 

After the flame is moved away, combustion 

must not continue for more than 30 

s, and any possible ignited drops must 

not set fire to neighboring parts or to the 

sheet of paper underneath the test sample. 

V0 

The test sample is in a vertical position and the flame goes out within 10 seconds 

without dripping 

V1 

The test sample is in a vertical position and the flame goes out within 30 seconds 

without dripping 

V2 

The test sample is in a vertical position and the flame goes within 30 second and 

dripping of the melted material is allowed 

5V 

This is the strictest classification, and entails two sets of tests: 

1 – a flame 127 mm long is applied for 5 seconds to the test sample in a vertical 

position, this is repeated for 5 times, at the end the flame must go out within 60 

seconds. Any drop of melted plastic must not set fire to a piece of cotton placed 

under the test sample. The procedure must be repeated 5 times. 

2 – The above test is run on 3 test samples put in a horizontal position. 

At the end of the test the material is classified as follows: 

5VB if there are holes due to the procedure 

5VA if there is no hole due to the procedure 

The above self-extinction grades are always associated to a minimum material 

thickness.

System. An intensity of 1 cd is the intensity of a source 

emitting monochromatic radiation:

and a power = 1/683w 

in a 1 sr solid angle

Photometry 

Photometric curve 

The whole of the measures of luminous intensities emitted by a luminaire in all directions forms the “photometric solid “. Usually not all information regarding the 

photometric solid is given, but only as regards two vertical planes normal to each other that cross the optical center of the luminaire. 

Luminous intensity values represented in polar co-ordinates on a plane define a line that is called 

“photometric curve”. They are generally expressed as cd/Klm, i.e. referred to a source emitting a luminous flux equal to a 1000 lm. 

Luminaire classification according to luminous flux 

DIN 5040 

Luminaire photometric classification as per this Standard is composed of one letter 

and two figures (ex.: A60). The letter (A, B ,C, D, E) indicates the percentage of luminous 

flux emitted in the upper and lower hemispheres. The closer it is to the letter A, 

the higher is the percentage of the flux emitted in the lower hemisphere. The figures 

that follow refer to the flux directed onto the working plane and to the ceiling, respectively, 

in the typical configuration provided for by the Standard. 

UTE C71-121 

Luminaire photometric classification is composed of the efficiency in the lower hemisphere 

followed by a letter plus the efficiency in the upper hemisphere followed 

by another letter (ex.: 0.50 D+0.24 T). Letters range from “A” to “J” and represent 

the luminous flux percentage inside given solid angles. If the letter T is present, this 

means that part of the luminous flux is emitted into the upper hemisphere. 

CIBSE TM5 

Luminaire photometric classification is divided into ten categories (BZ1 to BZ10). 

Each category refers to the percentage of luminous flux emitted in the lower hemisphere 

that directly reaches the working plane in a standard configuration. This is 

why this classification also depends upon room index. For example, luminaires classified 

as BZ1 emit a greater amount of luminous flux onto the working plane than 

BZ2 to BZ10 luminaires. 

Isolux Curves 

These curves connect points on the plane having same surface light density E (lux).

Surface light density calculations using the CIE method 

The formula to calculate the number of luminaires to be installed in a system is as follows: 

where: E med = required average surface light density (in lux), 

C m = maintenance factor, 

Φ = lamp flux per luminaire (in lumens) 

C u = utilization coefficient that can be obtained from the table below, near room surface reflectance 

and room index (K) 

Room index K is given by 

dove: 

a = room width 

b = room length 

h u = luminaire distance from the working plane 

Example: 

1. Room: a = 8 m, b = 4 m, h = 3m, h lav = 0,85 m, E med = 350 lux, C m =0.85 

2. 2- Room reflectance values: ceiling = 70% - frieze = 70% - walls = 50% - working level = 30% (the table 

column for the luminaire is no. 7553) 

3. Selected luminaire: ERRE D100R DARK 60°, 2x36w

Lighting engineering calculations

Glare 

When in the field of view there is a very high luminance, with respect to the field’s average luminance, a person’s visual capacity is decreased. This phenomenon is called 

“glare” and it occurs, for example, when at night we meet a car with its headlights on or when light sources, either direct or reflected, are within our field of observation. 

There are mainly two types of glare: 

• Disability glare which consists in an instantaneous deterioration of visual functions 

• Discomfort glare which manifests itself as a visual discomfort and not always causes strong visual inconveniences, but which, in time, causes visual problems, lower 

attention, more probabilities of error, poorer performance. 

Glare can be caused in two ways: 

• Direct glare 

It is caused by a luminance distribution which directly hits the observer’s eyes (light coming directly from a lamp or from lighting equipment) 

• Indirect glare 

It is caused by the reflecting image of the light source (naked light or equipment), from the surface of the visual display unit, from the walls or from particularly reflecting 

furniture. 

Indirect glare can be reduced as follows: 

• Paying attention to how lighting equipment and visual display units are arranged 

• using lighting equipment with an appropriate luminance so as to avoid reflections on visual display units or objects 

• Using non-specular and non-reflecting surfaces in the work area 

• Using diffused indirect lighting to reduce contrast 

In designing lighting engineering quality systems, it is necessary to follow the indications of the following regulation: 

• UNI EN 12464-1:2002 Light and Lighting. Lighting of work places. (ed. otober 2004) 

The regulation gives the limits of the average luminaire luminance at elevation angles of 65° and above from the downward vertical, radially around the luminaires for 

work places where displays screens, which are vertical or inclined up to 15° tilt angle, are used.

(UNI EN 12464-1:2002) 

The illuminance of immediate surrounding areas shall be related to the luminance of 

the task area and should provide a well-balanced luminance distribution in the field 

of view. 

The illuminance of the immediate surrounding areas may be lower than the task illuminance 

but shall not be less than the values given in the table beside.

UGR method (CIE 117-1995) 

The UGR (Unfied Glare rating method) was developed by CIE (Commission International de l’Eclarage) to harmonize glare classification procedures throughout the 

world. The formula for calculating the UGT is 

where: L = luminance of luminous parts of each device in the observation direction (cd/m 2 ) 

UGR = 8log ______ 0,25 ______ L2·ω 

Lb = background luminance (cd/m 2 ) 

ω = solid angle of luminous parts of each device referred to the observer’s eye (sr) 

p = indicates the Guth position for each device 

The above formula has been reported only for propaedeutic purposes and to show how the UGR calculation is quite complex when executed by hand and it is therefore 

necessary to use computerized calculation programs to be able to evaluate it. 

While the Söllner curve method serves to evaluate the glare of a single device, the UGR method serves to evaluate glare characteristics of a lighting system keeping 

into the account the contribution of each lighting devices, of the ceiling and of the walls with reference to one observation point. 

UGR values are expressed between 10 (lack of glare) and 30 (disability glare). Once the point of observation is defined, the UGR calculation is executed automatically 

using the computerized calculation program.

“CIBSE” equipment classification according to luminance 

The English CIBSE regulation classifies equipment according to three classifications depending on the angle beyond which the luminance value is lower than 200 cd/m 2 . 

Luminance contrast is carried out on four main planes: 0-180°, 90°, 270°, 135°-315°, 225°-45°, considering the position of the observer’s eyes. 

CIBSE LG3 CAT 1 CIBSE LG3 CAT 2 CIBSE LG3 CAT 3 

The equipment is classified as CAT1 if starting 

from an observation angle of 55° with respect to 

the axis, the reflector’s luminance is less than 

200 cd/m 2 .

The Visual Environment for Display Screen Use Introduction 

CIBSE - Lighting Guide 3: Addendum 2001 

The visual environment for display screen use 

The addendum 2001 must be read together with the previous 1996 edition. 

Considering the widespread market trend to specify the category “CAT” of the 

equipment without considering the current work environment in which it will be installed, 

the “category” system has been removed from the LG3 guide. 

In the future any specification relative to the characteristics of lighting equipment 

for use in premises with video display units, must be specifically defined by the designer 

or chosen by the supplier according to the information provided by the customer/user. 

Considering only the light distribution of each single lighting equipment, does not 

guarantee that a satisfying lighting system will be achieved and therefore in order 

for the designer to plan a system which satisfies the requirements of the LG3 guide, 

he must keep all the aspects (lighting uniformity, luminance distribution, type of activity, 

etc.) reported in the guide into consideration.
