IS 16103 : Part 2 : 2012 : LED modules for general lighting Part 2 Performance requirements

1. Scope

1.1 This standard (Part 2) specifies the performance requirements for LED modules, together with the test methods and conditions, required to show compliance with this standard. The following types of LED modules are covered in this standard:

a) Type 1 - Self-ballasted LED modules for use on dc supplies up to 250 V or on ac supplies up to 1 000 V at 50 Hz.

b) Type 2 - LED modules operating with external control gear connected to the mains voltage, and having further control means inside (semi-ballasted) for operation under constant voltage, constant current or constant power.

c) Type 3 - LED modules where the complete control gear is separate from the module for operation under constant voltage, constant current or constant power.

NOTES

1 The power supply of the control gear for semi-ballasted LED modules (Type 2) is an electronic device capable of controlling currents, voltage or power within design limits.

2 The control unit of the control gear for semi-ballasted LED modules (Type 2) is an electronic device to control the electrical energy to the LED’s.

3 A LED module with external control gear can be either a non-ballasted LED module or a semi-ballasted LED module.

This standard covers LED modules that intentionally produce white light, based on inorganic LEDs.

These performance requirements are additional to the safety requirements specified in IS 16103 (Part 1) : 2012 ‘LED modules for general lighting : Part 1 Safety requirements’.

Life time of LED modules is in most cases much longer than the practical test times. Consequently, verification of manufacturer’s life time claims cannot be made in a sufficiently confident way, because projecting test data further in time is not standardized. For that reason the acceptance or rejection of a manufacturers life time claim, past an operational time as stated in 6.1, is out of the scope of this standard.

Instead of life time validation this standard has opted for lumen maintenance codes at a defined finite test time. Therefore, the code number does not imply a prediction of achievable life time. The categories are lumen-depreciation character categories showing behaviour in agreement with manufacturer’s information which are provided before the test is started.

In order to validate a life time claim, an extrapolation of test data is needed. A general method of projecting measurement data beyond limited test time is under consideration.

The condition of compliance of the life time test as defined in this standard is different from the life time metrics claimed by manufacturers. For explanation of recommended life time metrics, see Annex C.

NOTES

1 When modules are operated in a luminaire, the claimed performance data can deviate from the values established through this standard due to the luminaire components that has an impact performance of the module.

2 The external control gears for LED modules as mentioned in Type 2 and Type 3 are not part of the testing against the requirements of this standard.

3 Protection for water and dust ingress (see B-4).

1.2 It may be expected that self-ballasted LED modules which comply with this standard shall start and operate satisfactorily at voltages between 90 percent and 110 percent of rated supply voltage. LED modules with external control gear are expected to start and operate satisfactorily in combination with the specified control gear complying with IS 15885 (Part 2/Sec 13) : 2012 ‘Lamp controlgear: Part 2 Particular requirements, Section 13 d.c. or a.c. supplied electronic controlgear for LED modules’.

All LED modules are expected to start and operate satisfactorily when operated under the conditions specified by the module manufacturer and in a luminaire complying with IS 10322 (Part 1) : 2012 ‘Luminaires: Part 1 General requirements and tests’.

1.3 For compliance with EMC requirements, only those types of LED modules are subject to EMC requirements which fall under the following category:

a) In case of harmonic current are directly connected to the mains and have active elements on board;

b) In case of radiated or conducted disturbances are directly connected to the mains (Type 1) or to a battery; and

c) In case of immunity are directly connected to the mains (Type 1) or to a battery.
