DC electronic ballast for tubular fluorescent lamps
Performance requirements
Part 1 General performance requirements
This standard specifies the general performance requirements for DC electronic ballasts with a rated voltage not exceeding 250V and used in conjunction with fluorescent lamps that comply with ISO60081. This standard should be used in conjunction with (B19510., B19510.%, 1395]0.7G3[9510,8). This standard specifies the general performance requirements and performance requirements for electronic ballasts used in communication lighting, public transportation industrial lighting and aircraft lighting.
Note 1: In order to achieve the required performance when working with fluorescent lamps and DC electronic ballasts, certain characteristics of their design must be appropriately adjusted. Therefore, the technical requirements for these characteristics must be formulated based on measurements made with a common baseline as the reference. This baseline must be relatively fixed and repeatable.
Note 2: These conditions can be judged by using a reference ballast. However, fluorescent lamp ballasts are usually tested using reference lamps: and in particular, the results obtained using the reference lamps of the ballasts under test are compared with the results obtained using the reference lamps of the reference ballasts specified in IEC 50921.

All tests shall be carried out under the conditions specified in Appendix A. All ballasts specified in this standard shall comply with the requirements of GB19510.5, GB19510.6, GB19510.7 and GB19510.8.

The following non-mandatory markings may be provided by the manufacturer: a) Ballast lumen factor,
b) Rated output frequency (when working with or without lamps at the design voltage). c) The limit of the ambient temperature range that enables the ballast to operate normally within the rated voltage range indicated. 5 Starting
It can be expected that the ballast that complies with this standard can start the lamp smoothly (not hot restart) when it is operated with the lamp that complies with the requirements of IEC60081 at the minimum voltage of the rated voltage range and the maximum temperature around the lamp is 10℃~20℃, and can also make the lamp work smoothly at other voltages within the rated voltage range and at an excitation of 10%~-5℃.

When the ballast is designed to operate lamps in a series circuit, the requirements apply only to individual lamps, regardless of the number of lamps installed. Lamps operated with electric ballasts conforming to this standard require starting aids as specified in IEC 60081, but the starting aids are placed 7 mm from the lamp when the maximum diameter of the lamp is 16 mm. During these tests, each cathode of the lamp is replaced by a resistor having a value corresponding to that shown in the table of parameters for the corresponding lamp in IEC 60081.
Note: Due to the wide range of supply voltages, the maximum values shown in Table 1 are greater than those recommended in IEC 60051. This will result in a reduction in the effective life of the lamp. 7 Preheating conditions
7.1 Minimum voltage on lamp cathode
When the cathode of each lamp is replaced by a resistor with the standard value specified in the parameter table of the corresponding lamp in IF60081 and operated at any voltage within the rated voltage range, the voltage supplied to each cathode by the ballast shall be at least 3.05V (effective value) for low-resistance cathode lamps and at least 6.5V (effective value) for high-resistance cathode lamps. 7.2 Maximum voltage on lamp cathode

When the cathode of the lamp is replaced by a resistor with a nominal value specified in the parameter table of the corresponding lamp in [FC60081], and when the voltage is within the rated voltage range, the voltage supplied by the ballast to each resistor shall not exceed 11.0V (effective value). If this voltage exceeds 11.0V (effective value), the resistor meeting the following requirements shall be used for adjustment and calibration. The value of the resistor is the value derived by substituting the nominal operating current of the lamp specified in the parameter table of the corresponding lamp in [FC60081] into formula (1): R
Where: I is the nominal operating current of the lamp. 11.0

8 Lamp current and luminous flux
The ballast shall limit the arc current supplied to the reference lamp so that the current value does not exceed 25% of the battery current supplied to the reference lamp by the reference ballast when the reference lamp is operated using the reference ballast! The ballast under test shall be operated at its design voltage and the applicable base ballast shall be operated at its rated voltage and frequency. Under the same conditions, the luminous flux ratio is not less than 95% of the ballast lumen factor. Note: Any test circuit that matches the circuit shown in Figure 1 can be used for measurement, but it is necessary to pay attention to the capacitance effect, the resistor should be non-inductive, and the instrument should be consistent with the frequency used.
The reference lamp should be measured and selected in accordance with the requirements of IF: 60921 and should have the characteristics specified in the parameter table of the corresponding lamp in IFC, 60081.
When measured in accordance with the requirements for reference ballasts given in 1F60921, the reference ballast shall have the characteristics specified in that standard and in the parameter tables of the relevant lamps in 11EC60081. 9 Supply current
When the reference ballast is operated at the design voltage with a base lamp, the supply current shall not differ by more than ±15% from the current indicated in ballast 1.
The supply shall be of low resistance and low inductance type (applicable when the battery is remote from the ballast). For ballasts powered by a central system (excluding electronic ballasts for general lighting), any effective alternating current component in the DC input current shall not exceed 10%, unless otherwise specified by the manufacturer. This value is determined by measuring the voltage across a non-inductive resistor connected in series with the input terminal of the ballast. The DC voltage drop across the resistor shall not exceed 2 times the design voltage. If the manufacturer indicates that the AC component in the DC input current is allowed to exceed 10%, the durability test shall be carried out at its effective value design voltage with a specified waveform.
10 Maximum current in any cathode lead (cathode preheat) The current flowing through any cathode terminal shall not exceed the value given in the parameter table of the corresponding lamp in IFE60081. During the qualification test, the applicable basic lamp is connected to the circuit to make the ballast work normally, and the supply voltage used is equal to the maximum value of the rated voltage range. The test shall be carried out according to the procedure of [EC, 6092] but using non-inductive resistors. 11 Lamp operating current waveform
When the ballast is operated with the reference lamp at its design voltage, the current supplied to the reference lamp in the steady state shall be such that the peak current does not exceed 1.5 times the nominal operating current of the lamp specified in the parameter table of the corresponding lamp in IFE60081, or does not exceed 3.5 times the measured effective value current of the lamp, whichever is lower. 12 Steady-state operation (for dimming ballasts only) During steady-state operation, the electrodes shall be kept at a sufficient temperature. This condition shall be satisfied by making the effective value of the lamp current equal to or greater than % of the base current within the dimming range. If the lamp current is less than 3% of the base current, the heating of the electrodes shall continue during lamp operation.
Note: The value of the electrode heating may be under study.
