3 Terms and definitions
The terms and definitions as defined in QB/T 2938 AND the following terms and definitions apply to this document.
3.1
Initial luminous efficacy for single-capped electrodeless fluorescent lamps
The ratio of the initial luminous flux of the single-capped electrodeless fluorescent lamp to the measured power (external coupling is the lamp power, AND internal coupling is the lamp-ballast system power).
3.2
Minimum allowable values of energy efficiency for single-capped electrodeless fluorescent lamps
The allowable minimum initial luminous efficiency of a single-capped electrodeless fluorescent lamp under the test conditions as specified in this standard.
Appendix A (Normative)
Internal coupling electrodeless fluorescent lamp luminous efficiency test
A.1 Test conditions
A.1.1 Ambient temperature
The test shall be carried out in an airless convection chamber AND at an ambient temperature of 20 °C ~ 27 °C.
A.1.2 Supply voltage and frequency
A.1.2.1 Test voltage and frequency
When the ballast is marked with the supply voltage range used, OR when the ballast has several different independent rated supply voltages, AND any predetermined voltage for this ballast can be selected as the rated voltage.
The power frequency input into the ballast shall be 50 Hz.
A.1.2.2 Power supply stability
The supply voltage shall be stable within ± 0.5% of the rated voltage. However, during actual measurement, the voltage error shall be adjusted to within 0.2% of the rated voltage.
A.1.2.3 Test supply voltage waveform
The total harmonic content of the test power supply voltage shall not exceed
3%; the harmonic content is defined as the sum of the effective value of each harmonic component (r.m.s.), AND the base wave is defined as 100%.
A.1.3 Magnetic effect
There shall be no magnetic objects within the range of 25 mm from the surface of the tested ballast, unless otherwise specified.
A.1.4 Installation of internal coupling electrodeless fluorescent lamps
In order to ensure uniformity of the electrical characteristics of the lamp, the lamp's measuring position shall be as described in the lamp parameter table. If the lamp's parameter table does not provide installation instructions, the lamp shall be installed horizontally.
The test position of the lamp shall be consistent with the position at the preheating stage.
