Abstract
The invention relates to an LED module (1), comprising: connections (2) for an LED array (3); a circuit (4) which is configured to constitute a load, preferably an effective power load, if during a starting phase a constant current or a constant voltage is applied to the LED module (1), and which is configured not to constitute a load when the starting phase has finished, wherein the circuit (4) is designed to constitute a variable-current load which effects a change in the power consumption of the LED module (1) according to at least one predetermined protocol effected.
Claims16
An LED module (1) comprising:
- connections (2) for an LED string (3);
- a circuit (4), which is configured to constitute a load when a constant current or a constant voltage is applied to the LED module (1) in a starting phase, and which is configured to constitute no load when the starting phase has elapsed, and
- an LED converter comprising a converter with high-speed clocking having a transformer, the converter with high-speed clocking being operated at least in the starting phase as constant current source and is configured:
- to detect a power consumption of the LED module (1) on a primary side of the transformer during said starting phase, and
- to determine, on the basis of the detected power consumption, at least one of:
- an operational or a maintenance parameter of the LED module (1), wherein
- the circuit (4) is configured to constitute a variable-current load, which effects a change in the power consumption of the LED module (1) in accordance with at least one preset protocol.
An LED luminaire, comprising an LED module (1) having:
- connections (2) for an LED string (3);
- a circuit (4), which is configured to constitute a load, when a constant current or a constant voltage is applied to the LED module (1) in a starting phase, and which is configured to constitute no load when the starting phase has elapsed, wherein
- the circuit (4) is configured to constitute a variable-current load, which effects a change in the power consumption of the LED module (1) in accordance with at least one preset protocol;
- and an LED converter (10) comprising a converter with high-speed clocking having a transformer, the converter with high-speed clocking being operated at least in the starting phase as constant current source and is configured:
- to detect a power consumption of the LED module (1) on a primary side of the transformer during said starting phase, and
- to determine, on the basis of the detected power consumption, at least one of an operational or a maintenance parameter of the LED module (1).
