On account of their great advantages compared to conventional gear,
high-frequency (HF) electronic ballasts have gained great popularity in
many applications over the last decade.The use of electronics
provides more comfort and flexibility, whilst the light can be easily
regulated to one’s own requirements.Another highly relevant benefit
of HF lighting is the fact that considerable cost reductions can be
obtained thanks to the energy-saving qualities of HF electronics.
Besides, the compact electronic components of these days allow for a
new innovative design of luminaires.A typical example of this is the
TL5 system.
The built-in quality of Philips lighting components
In many laboratories all over the world, lighting engineers are working
hard on constant improvement of Philips products, including ballasts,
for the provision of reliable and first-rate lighting installations.
Obviously, great emphasis is thereby laid on quality in terms of
performance, lifetime and similar aspects.
Philips HF electronic ballasts are manufactured in ISO 9001-certified
factories.All ballasts fulfil the relevant international norms, ensuring
optimum performance and safety for those who are going to work
with and in the new lighting installation.
But in the Philips vision that is not enough.Also easy installation and
operation are critically taken into account during the product
creation process.And the opinion of the end-user is highly valued in
this process.
On top of that, Philips also take full responsibility for the care of the
environment and are therefore ISO 14001-certified.This implies that
the use of Philips HF electronic ballasts ensures the fulfilment of the
environmental management system, as certified by the official
approval of the Dutch test authority KEMA.

In this guide useful hints and tips can be found on how to apply HF
electronic ballasts in a lighting installation. Subjects that will be dealt
with include: the proper construction of luminaires designed to be
equipped with HF control gear, as well as how to install and operate
such luminaires.Also aspects like testing, trouble-shooting and
maintenance will be covered.
The interaction between HF lighting installations and the environment
will receive special attention too.
Finally, a few words will be spent on dimming and emergency lighting,
and the guide concludes with a list of literature for further reading.

Obtaining an outstanding lighting installation is not simply a
matter of choosing the best possible components: their
proper installation and operation in the system is equally
important.

Introduction
Unless specially mentioned, it is assumed that the HF ballasts are
mounted in a Class I luminaire (provided with an earthing point), and
that they are electrically very well connected to some metal part of
the luminaire.
For ballasts housed in a metal case this is normally obtained by means
of the fixing screws with which the ballast is mounted to the earthed
mounting plate.Tooth-lock washers should be used to ensure a
proper earth contact right through the paint or lacquer covering the
luminaire. Fixing screws for mounting the ballast should be 4 mm dia.
Ballasts in a plastic housing must be earthed via the connector.
Generally speaking, fluorescent lamps at all temperatures require an
ignition aid for proper ignition.This is stated in IEC 60081 - Annex A.
If a certain type of lamp does not need an ignition aid, this must be
specifically mentioned in the relevant lamp documentation provided
by the lamp manufacturer, for example, PL-T lamps.
What is an ignition aid?
An ignition aid, sometimes also called ‘starting aid’, is a metal plate
with a length extending at least over the lamp length and a width of at
least 1.5 times the lamp diameter. It should be connected to earth (or
to an earth contact on the ballast).
Typically, the distance between the ignition aid and the surface of the
lamp should be:
20 mm for ‘TL’D lamps,
6 mm for TL5 lamps,
12 mm for PLL lamps.
Note:
Under no circumstance should there be any conducting (metal) plate
between the ignition aid and the lamp, unless it is electrically connected to
the earth point of the luminaire (or an earth contact on the ballast).
This also applies, for instance, for an aluminium reflector.
The ignition aid must directly face the lamp.
When and how to use an ignition aid
• For Class I (i.e. mains earthed) metal luminaires a separate ignition
aid will in general not be required, as the luminaire itself will fulfil
this function.
• For Class I plastic luminaires, a separate ignition aid has to be
mounted and connected to earth.
• In the case of Class II luminaires (no provision for protective
earthing), the ignition aid must be connected to the earth connector
of the ballast.
What to do if the use of an ignition aid is not
possible?
The proper ignition of the lamps will depend on the type of ballast,

2.3 What to do if the use of an ignition aid is not possible
the position of the ballast and the wiring between the ballast and the
lamp(s).
For this reason, luminaires without ignition aid can only be released
after testing.
In general, 250V-rated electrical components and 300V-rated wiring
(as H05 classification) can be used in luminaires.
Exceptions to this rule are the dimming systems for PLT and TL5.
Here, 500V-rated lampholders and 450V-rated lamp wiring (like H07)
have to be used, on account of the high lamp voltages (up to
430Vrms).
Normal ‘H07’ wiring has a minimum conductor cross-section of
1.5 mm2.
The HF-REGULATOR ballast is suitable for such a conductor
thickness, but most TL5/PLT lampholders can only cope with a
maximum wire cross-section of 1.0 mm2. In that situation, ask your
local cable supplier for 450V-rated wiring with a conductor thickness
of 0.5-1.0 mm2.
Note: High lamp voltages may arise when fluorescent lamps are dimmed. If
this happens, it has always to do with the chosen lamp concept and is not
dependent on ballast technology.
General wiring
It is important to heed the following indications if optimum system
performance and minimum radio frequency interference are to be
obtained:
• Keep mains (and control) wiring away from lamp wiring and lamps
(minimum distance 2 cm) (see Fig.1).
• If complete separation is not possible, screen the mains (and
control) wiring by an earthed metal sheath or plate.
• Keep mains (and control) wires as short as possible.
• As a general rule, the length of the wires should be in accordance
with the advised figure for the relevant ballast type.
• Avoid loops in all wiring.
• Take care of firm electrical contact between all metal parts and the
ballast housing.
Control and lamp wiring (regulating ballasts)
In the case of control wiring, the following points should be regarded:
• The wiring to the control input must be dealt with like mains wiring.
• Do not short-circuit the lamp wires for more than five minutes.
Otherwise, the ballasts may be damaged.
Special wiring
In the case of throughput wiring:
• Take extra care that throughput wiring in a luminaire is completely
separated from the lamp wiring in order to avoid deterioration of
the EMC behaviour of the luminaire.
Changing from conventional to HF gear
HF electronic ballasts consist of one single unit, replacing various
components in conventional electromagnetic systems, such as a radio-
interference capacitor, a starter and an electromagnetic ballast.
When changing from a conventional ballast system to an electronic
one, but also when swopping from one electronic ballast to another, it
is advised to check:
1.The quality of wires and lampholders (ageing). If these components
are not in optimum condition, replace all existing wiring before
installing a new electronic ballast.Also all the redundant
components of the previous electromagnetic system should be
removed.
2. Follow the hints as given in section 2.4.1: General wiring.
Wiring for luminaires with three or four
HF-P ballasts
When three or four HF-PREFORMER (HF-P) ballasts are used in a
Class I luminaire, the maximum earth leakage current may surpass the
maximum allowed 1.0 mA (according IEC 598).
Reverse-connecting the mains and neutral on one or two of the
ballasts in the luminaire will cause the maximum earth leakage
current to fall below the required 1.0 mA.
