If you want to knowHow an LED lamp works? In this article we present all the outstanding details of this type of lamp or bulb, which provides us with a pleasant white light that, for our benefit, lasts for many years and consumes very little energy. So thanks to this, incandescent bulbs have disappeared.
Learn about the advantages and uses of LED bulbs.
How does an LED lamp work?
At the time that Albert Einstein received the Nobel Prize in Physics, it was not for his theory of relativity, this was thanks to a more modest study, such as the photoelectric effect. Einstein wrote this how some materials, when subjected to an electric current emitting light.
The light produced by means of the photoelectric effect has a certain frequency, that is, a single color, which depends on the type of material used. There are also contrary effects to this, which causes solar panels (photovoltaic) which produce electricity when exposed to light.
It is known that LED diodes have been known for over 60 years, these are red and green LEDs found in all electronic devices. Inside the plastic cap of the LED diodes, we can find a semiconductor material. When applied to an electrical current, when the current passes through the semiconductor it produces light.
This light emits it without producing almost no heat, and with a color already determined, depending on the semiconductor material, a light of one color or another will be emitted. This color can become invisible to the human eye, only the infrared LEDs, which are found in the remote TV controls.
How does an LE lamp work: Types of lamps?
We can find all types of different lamps, as with globe bulbs, candle sphere and 2 different types even to recess and supply the old halogens. The two types that we can find are: GU10 LED bulbs that work at 230V, for normal voltage in homes and MR16 or GU5 LED bulbs that work with 12V as well as halogens.
Change Halogen for Led
It is very easy to change a halogen for an LED lamp, but be very careful. The first thing to do is, check at what voltage do our halogens work? There are 2 types, those that work at 12V and those that work at 230V and for each different situation.
Some that work at 12V and for this reason have their own transformer in the installation to convert the 230V of the home into 12V. On the other hand we have those that work at 230V directly, at home voltage. For 12V ones, the first option is to eliminate the transformer, bridge and replace the lamp with a GU10 LED.
A separate option is to leave the transformer and directly change the halogen lamp for an MR16 or GU5 LED. The most affordable option is to eliminate the transformer by bridging, although it is more work than the second option.
Advantages of LED Bulbs
- Size: Like lighting, an LED bulb takes up less space than an incandescent bulb.
- Brightness: LED diodes are brighter than a normal light bulb, and furthermore, the light is not concentrated at one point, like the filament of the light bulb, but the diode shines in the same way.
- Duration: an LED bulb can last for 50.000 hours, which is equal to six years constantly on. This is 50 times more than an incandescent light bulb.
- Consumption: a traffic light that switches to LED bulbs will consume 10 times less with the same amount of light generated.
