Compared with the previous version, the new version includes the following major technical changes:

1. PELV and related requirements are added. Due to transient protection circuit and EMC reasons, PELV circuit has a strong demand in the market. Considering IEC TR 63139 (under development), PELV is added everywhere in the standard where SELV appears. Relevant modifications of PELV include chapter 3, Chapter 4, Chapter 7, Chapter 8, Chapter 10 and appendix X;

2. Table 10.3 and article 3.3.19 are modified. In case of high protection current, the limit of power supply current above 20A shall be added on the basis of the original applicable object according to the provisions stated in 3.3.19 in the manual, that is, the applicable object of the clause is that the power supply current is more than 20A and the protective conductor current is higher than 10 Ma, and the corresponding limit value in table 10.3 is changed from 10mA to 10mA or according to the manufacturer's instructions;

3. Clause 3.3.26 added the marking provisions for the wall mounted lamps within the reach arm, and required to add the description of fixing the cable to the wall;

4. Requirements for constant light output function and programmable current output are added in Clause 3.2.27;

5. Clause 4.30 covers for protection against electric shock for luminaires with non user replaceable light sources;

6. In 4.24.2, category 0 hazard is deleted;

7. Clause 5.2.16 added the component Standard IEC 61984 that the connector should comply with, as well as additional requirements such as polarity exchange, mechanical locking, electric shock protection, short circuit protection, cable clamping, etc;

8. 3.25 for UV protection;

9. Clause 4.34 requires that luminaires shall not emit harmful electromagnetic fields and shall comply with EMF IEC 62493;

10. Updated section 1.2.73 The functional grounding and protective grounding and their requirements in this standard include the addition of definitions and the addition of the qualifier of "function" or "protection" in "grounding"; in Appendix g, the description of functional grounding (if separate) disconnection when measuring the current of protective conductor is supplemented, and the accessible functional grounding terminal or contact shall be regarded as touchable when measuring contact current And the components are tested;

11. Clause 4.35 provides test provisions to prevent touching motor-driven fan blades in lamps for cooling, and gives conditions for exemption from tests, such as low hardness, low speed and low power;

12. Clause 3.2.2 modifies the marking requirement for rated voltage by deleting the case where it is not necessary to mark the rated voltage, i.e. all lamps shall be marked with rated voltage in volts;

13. In article 5.2.10, it is stipulated that the flexible wire holder can be used as an exception when meeting 5.2.10.4. The additional 5.2.10.4 specifies the exceptional conditions, including the maximum short-circuit current before the over-current protection device does not exceed 2a, the maximum voltage of various class III lamps, and the corresponding qualification test requirements;

14. The measurement of current and contact current in the conductor protection network in Appendix G is modified;

15. The contact voltage limit of irregular DC voltage in 8.2.3c) is modified;

16. Clause 1.2.96 Luminaires (POE) connected by an Ethernet power supply dependent on the power supply to IEC 62368-3, covering the definition, construction, thermal test and appendix introducing Poe luminaires;

17. Ipx9 (80 ℃) for high-pressure and high-temperature water blowout prevention and ipx9 (15 ℃) for high-pressure and low-temperature water blowout prevention and their test requirements are added in Article 9 IP;

18. Appendix D is modified to introduce alternative thermal test for lamps with TA marking higher than 25 ℃;

19. In Clause 0.2, 4.14.1 is added to add relevant requirements of guide rail luminaires, including definition, adding rail mounted Luminaires in 4.14.1 test objects, and adding a requirement in Chapter 4, that is, rail mounted luminaires shall also be tested in accordance with Appendix A of IEC 60570;

20. Article 10.2.2 is modified to increase the electrical strength of DC lamps;

21. Appendix D is modified and the temperature limits are added to table 12.1 and table 12.3. For lamps marked with F, the covering layer is changed to direct contact with the lamp instead of covering the outside of the box previously;

22. The minimum torque of metal gland test in table 4.2 is reduced from 6.25 nm to 4 nm;

23. Modify the requirements for protective impedance devices (4.10.4) in section 4.10.4 and appendix u, change the quantity requirements of Y1 and Y2 into tabular expression, and specify the required number of capacitors according to the power supply voltage, impulse withstand category, jumper insulation and capacitance type (Y1, Y2 or Y4). The relevant modifications involve Chapter 4 and appendix U;

24. The second paragraph of 5.2.14 is modified. For class III plug used in lamps, the original requirement that class III plug cannot be connected to grid power socket shall be changed from "unable to be connected" to "unable to be electrically connected", and test method shall be added. The relevant modification involves chapters 5 and 4.
