1. Resolution number：DSH 2047

Standard number: IEC 60598-1/2008; IEC 61347-1/2012;IEC 62031/2014;IEC 62560/2015

Section number: 13.3.1 – 13.3.2; 14.5 – 18.3 – 18.4; 13.2; 12

The original resolution

Problem: It is necessary to confirm whether the specification of the thin paper in the lighting standard adopts the correct section number of ISO 4046-4.

The resolution concluded that the hot wire/needle flame test and fault test can be tested in accordance with the horizontal base standards (e.g. IEC 60695-2-10, IEC 60695-11-5), so the thin paper described in the horizontal base standard can be used.

Clarification: the thin paper used for horizontal base standards is equivalent to the thin paper described in ISO 4046-4 4.187 and 4.215.

2. Resolution number:  DSH 2049

Standard number: IEC 60598-1:2014

Section number:  5.2.10.1

The original resolution

Problem: The LED floodlight was tested in accordance with IEC 60598-2-5. 5.2.10.1.

Some settable LED floodlight does not provide line and plug, only provide a gland and/or a soft line fixture in many cases, the gland without any device to grip the cord (see below) standard can be used as a soft gland 5.2.10.1 specified line fixture, unless they are for the power connection of all types and sizes of soft cable cord has a clamping device, however, in many gland just provide a silicone ring, which is not suitable for as cord anchor device almost all actual test proves that this kind of situation

(1). Does soft wire fixtures needed for this type of floodlight? They are known to be fixed fixtures, but most are installed by customers with a soft line. Can IP levels be maintained? Particularly noteworthy is the use of soft cable connections for floodlight design, but there is no information in the specification.

Does this structure meet the standard requirements if the flexible wire fixture is required?

(2). How much minimum is it necessary to pass a soft cable of 1.5mm2?

Resolution conclusion:

A1: For this kind of structure, if there is no information about how to connect to lamps and lanterns, the instructions must have a flexible wire fixing device in general, installation instructions should address the types of the flexible cable installation or provide catheter in the case of using catheter, don't need soft wire fixing device;

However, if the installation instructions require a power cord, a flexible wire fixture is required.

A2: if the sealing gland is equipped with clamping device to clamp the cables of various sizes (minimum 1mm2), then the sealing gland can be used as a flexible wire fixation device.

A3: the installation specification should give a proper description of the type of cable used. The opening should be suitable for the cables specified in the instructions.

3. Resolution number: DSH 2050

Standard number: IEC/EN 60598-1 all versions.

Section number: 7

The original resolution

Problem: In the structure of the class of lamps shown below, which ground wire is through a metal fastener is connected to the metal framework of lamps and lanterns metal fasteners by nails fixed on the metal frame - the lid of lamps and lanterns of lamps and lanterns this structure provide permanent earthing terminal and lamps and lanterns of the connection between the metal cover 7.2.3 test can through this kind of structure is acceptable?

The grounding terminal and the lamp metal cover are permanently and reliably connected.

Conclusion the resolution

This structure can accept chapter 15 shall not apply, because there won't be permanent current earthing terminal, and there is no standard corrosion problems covered by other parts LUMEX confirm this connection security chapter 4 and chapter 7 is enough

4. Resolution number: DSH 2052

Standard number: IEC 60598-1:2014;IEC 62504:2014

Section number: 4.24.

The original resolution

The problem is in the clause1.2.88 of the IEC 60598-1, the light source is defined in the broadest sense, which including the use of laser technology produces visible light. In addition, the IEC 60598-1 requires the use of IEC/TR 62778 assessment of the dangers of light, but do not include laser for lamps and lanterns with a single light source, such as the LED module and visible light lamp contains a laser light source, will be applicable to the IEC 60825-1 of clause 4.4 (laser product design as a traditional lamp)

Resolution conclusion: this product is suitable for the IEC 60825-1 of clause 4.4 which IEC 62471 was used to assess possible because in IEC 60825-1 is mentioned in clause 4.4 of the IEC 62471, should be based on IEC/TR evaluation because the IEC 62778 / TR 62778 and IEC 62471 use the same limit, and IEC/TR 62778 have been related to the product standard reference, such as IEC 60598-1.

To sum up, if the lamps and lamp bulbs use a laser light source that can produce visible light, the IEC/TR 62778(380-780 nm) can be evaluated according to the IEC 60825-1 4.4 terms

5. Resolution number: DSH 0816A

Standard number: IEC 60598-1 all version

Section number: 0.2.

The original resolution:

The problem is we have a rechargeable lamp that can be installed in a socket. Only when the power supply is insufficient, can we light it. Can we use IEC 60598-1 as a portable lamp for this kind of lighting?

Conclusions: IEC 60598-1 and the appropriate part 2 are applicable, and the transformer standards (IEC 61558-1), battery chargers (IEC 61347-2-11 and IEC 61347-2-7, chapters 22 and 23) are considered, and the plug (IEC 60884-1).
