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. | Status: Current

1 Scope This International Standard 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, having:

• — 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 standard 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 IEC 60598‑1 Table Q.1, column class III luminaire, column 4 or 5.

NOTE 2 Where in this standard the term “lamp(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. 230 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. Figure 1 — Types of LED lamps with supply voltage ≤ 50V a) Example of a non-integrated LED lamp with supply voltage ≤ 50V b) Example of a semi-integrated LED lamp with supply voltage ≤ 50V, in the scope of this standard Key Key 1 Converter not LED specific, but designed typically for incandescent or tungsten halogen lamps. 1 Converter not LED specific, but designed typically for incandescent or tungsten halogen lamps. 2 Non-integrated LED light source, typically a module. It may have an IEC 60061‑1 conform cap which is LED specific and not retrofit. 2 LED control unit. 3 Semi-integrated LED lamp as defined in 3.15.4 of IEC 62504.

NOTE Figure 1a) type is not covered by this standard.
