Dimming of LED light sourcesAdditional information
It is said that LED light sources are TOP of the market and are now used in 80% of buildings and homes to save costs. However, it is more difficult to define a load of LED sources on the dimmer with the aim of trouble-free regulation. Each dimmer has overcurrent protection that reacts at certain peak current.
Each load (bulb, LED, energy-saving lamp) has a certain power consumption. This is usually stated on the packaging by the manufacturer. However, the peak current value of this load is usually not stated. This is because each LED or energy-saving lamp has electronics inside, peak current values may vary considerably for different products. Generally, it is not possible to determine the number of individual LED bulbs, if we do not know this value; we can only test a specific number of pieces. The solution to the determination is by the power factor cos φ. The power factor of dimmable LED lamps ranges from cos φ = 0.95 to 0.4. You can get the approximate max. Load value by multiplying the dimmer load and the power factor of the connected light source.
