LEDsi lamps for general lighting services with supply voltages not exceeding 50 V a.c. r.m.s. or 120 V ripple free d.c. - Safety specifications
1 Scope
This document specifies the safety and interchangeability requirements, together with the test methods and conditions, required to show compliance of LED lamps with integrated means for stable operation, intended for domestic and similar general lighting purposes.
The scope of application is as follows:
——a rated power up to 60 W
——a rated voltage equal to or less than 50 V a.c. r.m.s. or equal or less 120 V ripple free d.c.,
——caps according to Table 1.
Note 1: The value of 60 W rated power is under consideration. Heat management may require lower power.
This document shall be used for products in conjunction with ELV lighting installations.
With reference to IEC 60364-7-715, in ELV lighting installations only SELV sources are applied. Where bare conductors are used, the maximum lamp voltage shall be 25 V a.c. or
60 V d.c.
The requirements of this standard relate only to type testing.
For lamps > 25 V a.c. or 60 V d.c., recommendations for whole production testing or batch
testing are given in GB/T 7000.1-2023 Table Q.1, column class III luminaire, column 4 or 5.
Note 2: Where in this standard the term “l(fā)amp(s)” is used, it is understood to stand for semi-integrated LED lamp(s) with supply voltages as in the scope above, except where it is obviously assigned to other types of lamps.
An overview of systems composed of LED modules, lamps and controlgear is given in IEC 62504. Supply voltage does not mean necessarily mains voltage, e.g. 220 V / 50 Hz. A semi-integrated LED lamp can also be driven on a supply voltage with 12 V a.c. or d.c. The control unit in the controlgear in a semi-integrated LED lamp then provides the conversion of 12 V a.c. or d.c. to a special current and voltage to power the LED inside the semi-integrated LED lamp. Schematically, the types of LEDni and LEDsi lamps are shown in Figure 1.

Information about the relevant UV hazard function is given in IEC 62471. It only relates to possible hazards regarding UV exposure of human beings. It does not deal with the possible influence of optical radiation on materials, such as mechanical damage or discoloration.
4 General requirement and general test requirements
The requirements of IEC 62560 apply.
5 Marking
The requirements of IEC 62560 apply.
Deviating from the frequency marking in IEC 62560, 5.1 d), the following applies.
If a lamp is only suitable for DC, it shall be marked "DC" or "—" (IEC 60417-5031).
If a lamp is only suitable for AC electronic, it shall be marked “AC electronic” or “～electronic” (IEC 60417-5032).
If a lamp is only suitable for AC 50 Hz/60 Hz, it shall be marked “AC 50 Hz/60 Hz” or “～50 Hz/60 Hz".
If a lamp is suitable for AC electronic and AC 50 Hz/60 Hz, it shall be marked “AC”; the addition “electronic and 50 Hz/60 Hz” is optional.
If a lamp is suitable for DC, AC electronic and AC 50 Hz/60 Hz, it shall only be marked with the voltage, not with the frequency.
Lamps with bulbs not suitable for water contact shall be marked with the symbol according to Figure 2. The marking shall be provided on the packaging or accompanying information. The height of the graphical symbol shall be at least 5 mm. The symbol is not needed if a written cautionary notice is provided.
