AC and/or DC-supplied electronic control gear for tubular fluorescent lamps - Performance requirements

This international Standard specifies performance requirements for electronic control gear for use on a.c. at 50 Hz or 60 Hz and/or d.c. supplies, both up to 1 000 V, with operating frequencies deviating from the supply frequency, associated with fluorescent lamps as specified in IEC 60081 and IEC 60901, and other fluorescent lamps for high-frequency operation.
NOTE 1 Tests in this standard are type tests. Requirements for testing individual control gear during production are not included.
NOTE 2 There are regional standards regarding the regulation of mains current harmonics and immunity for endproducts like luminaires and independent control gear. In a luminaire, the control gear is dominant in this respect. Control gear, together with other components, should comply with these standards.

8.3 Requirements for dimming
Replace the entire subclause with the following new subclause:
8.3 Requirements for dimming
8.3.1 Heating of the lamp cathodes
8.3.1.1 General

Fluorescent lamps operated in dimming mode (to reduce luminous flux by reducing discharge

current) need their cathodes adequately heated by the electronic control gear. It has been

found that measuring the currents through the two lead-in wires to the cathode and calculating

the sum of the squares (SoS) of these two currents as a function of the discharge current can

estimate the cathode heating. Alternatively, it has also been found that it is possible to

estimate cathode heating by measuring the voltage applied across the cathode (CV) while

dimming. The heating requirements are described in IEC TR 62750:2012.

The control gear is tested at lamp discharge currents (dim levels) of I , I and I . The

Dmin D30 D60

measurements are conducted with substitution resistors for the cathodes (R ) and for the

test

discharge, the latter dependent on the dim level (R , having nominal values of R and

L L10Max

R as well as R and R ). The lamp substitution resistor values shall be taken from

L10Min L30 L60

the IEC lamp data sheets. Take care that the substitution resistors are capable of carrying the

current, voltage and power occurring in the circuit.

All positions that on control gear that would be connected to a lamp shall instead be

connected to substitution resistors. Wherever in this procedure a reference is made to “lamp”,

it is intended to mean a set of substitution resistors that represent a lamp.

The hot spot location may vary on the lamp cathode during operation. This effect is simulated

in the test by connecting the cathode substitution resistors in different circuit configurations.

For this purpose, taps in the middle and at the ends of the cathode substitution resistor

networks are equipped with switches (0 – 50 – 100 method), which allow all possible

combinations of connection to be realized. The fundamental test set-up is shown in Figure 3.

In cases where the discharge current is much smaller than the auxiliary heating current,

i.e. for the upper and lower heating limits at very low discharge current values (= 10 % of the

test current), the cathode lead wire currents are found to be nearly equal.

Thus, for the CV-test, only the centre tap position is required for testing. The CV-test setup

shown in Figure 4 is a simplified version of the SoS-test circuit.

8.3.1.2 Basic test conditions

Due to the lamps being operated at high frequency, the test set-up with substitution resistors

should be comparable to the set-up of the real luminaire. Relevant examples are given in

Annex F.

Check the suitability of the lamp and cathode substitution resistor set-up at high frequencies

for the frequency range used by the control gear.

Maintain the maximum contact resistances, parasitic inductances and coupling capacitances

of the cathode circuits in test with the lamp dummy inserted (see Table 2).

R (contact resistances for each heating circuit)

C (from heating circuit to heating circuit) 20 pF

The values of L, R, C , and C are measured at the lamp wires next to the electronic control

gear’s lamp terminals. For this purpose, instead of a lamp, the cathode substitution resistors

R are inserted in the test set-up.

Output circuits of electronic control gears, designed for multi-lamp operation, are each tested

separately. The output circuits not involved in the test shall be connected to the substitution

resistors with equal value to the output circuit which is under test. The variations of the

cathode terminal switch take place only with the output circuit under test. For the other

circuit(s), the switch is connected to the middle position (positions 2 and 5 in Figure 3).

Lamp substitution circuits, supplied from multi-lamp electronic control gears (i.e. gears which

operate more than one lamp simultaneously), shall each be wired separately when connected

with the DUT (device under test). This means that each electrode substitution resistor is

equipped with 2 cables, leading to the terminal of the electronic control gear and having an

immediate connection according to the electrical circuit design. Each pair of one electrode

substitution resistor’s cables shall be installed together.

For wiring of the test set-up, H05V-U cables (or equivalent) shall be used. When designing

the wiring layout, the values of the parasitic losses shall be in the same order for all lamp

circuits. This can be achieved only if the wiring of the lamp circuits is comparable in

distances, lengths, etc. and each pair of lamp circuits is located symmetrical to the axis of the

device.

Check the suitability of the instruments, i.e. the tolerance at the range of expected frequency

and amplitude.

For the r.m.s. current measurement, the measurement period shall be an integer multiple of

the mains half wave period.

If the electronic control gear allows operation of different lamps with varying operating

parameters, then safeguard with suitable means so that during operation at the lamp dummy

the correct choice of parameters for that lamp(s) has been made.

Compliance with the cathode heating conditions shall be tested with each alternative lamp

type.

To ensure that control gear reaches the operating state (to “start” the substitution resistors),

the procedure may be modified and/or a special prepared control gear may be used, provided

the cathode heating would be the same as a production control gear.
8.3.1.3 General test sequence

Table 3 gives an overview of the values for the different dimming levels which shall be

measured and controlled. If an electronic control gear is designed for more than one lamp,

then the same measurements and tests shall be conducted as for Lamp 1. Table 3 includes

also the switching position for the simulation of the arc spot and the correlation to the test

method (CV or SoS).
