Why did the development of LEDs bring about a revolution in lighting?

Why did the development of LEDs bring about a revolution in lighting?

As an alternative to traditional incandescent bulbs, lamps LEDs allow considerable energy savings. They can be up to 2000% more efficient than conventional bulbs and 500% more efficient than compact fluorescent bulbs.

Why Can we say that LED lamps are a promising technology for the future?

A promising technology Among the advantages of the LEDs compared to others technologies : its duration of life. She can go “up to 40,000 hours against 2,000 h to them lamps halogens and 8,000 h to them lamps compact fluorescents”. Of moreover, they are insensitive to shocks.

How to vary the intensity of the current?

Installing a power variator First of all, it is essential to cut off the electric current. You will then need a screwdriver to remove your old switch. Once the box is removed, you need to connect the power wires to the new equipment.

How to measure the light intensity of LED lighting?

To measure the light intensity of LED lighting, you would use an LED light meter., LED lighting has become increasingly common in commercial settings due to energy efficiency, longevity, adjustability color temperature, safety and low maintenance.

How to measure the luminous intensity of an LED?

The current flowing through the LED determines the light intensity emitted. Note: Some diodes have build voltages on the order of 3 volts and higher. In some cases, one may need to reverse bias the LED.

How to measure the light intensity of a diode?

The current flowing through the LED determines the light intensity emitted. Note: Some diodes have build voltages on the order of 3 volts and higher. In some cases, one may need to reverse bias the LED. The diode is then off: it no longer emits light intensity.

What is the difference between a bulb and an LED?

The difference of the LED comes from the fact that the light does not come from the heat but from the components of the bulb itself. When the current passes through an LED bulb, it does not produce heat (or infinitely little) but light.
