LED lights are known to be very economical, but what is the real power consumption? Is it worth replacing old light sources with LEDs?
Hãy cùng xem đèn LED thực sự tiêu thụ bao nhiêu năng lượng và chúng ta có thể tiết kiệm được bao nhiêu chi phí điện năng với công nghệ LED.
In commercials for LED lights, great savings in power consumption are often promoted. In theory the energy consumption of LED luminaires and light bulbs is much lower than with conventional lamps. Tuy nhiên, actual power consumption and savings depend on several factors, such as brightness, efficiency.
The brightness of LED lamps is no longer indicated in watts, but in lumens. Tuy nhiên, the energy consumption still results from actual power draw in watts. If an LED light is specified as 5 watt, this is the power consumption when switched on. But the wattage says nothing about the power consumption. The real consumption is calculated by multiplying the power consumption with the real burn time of the lamp.
