Since 1962, the date of birth of the first Diode Electro Luminescente (in french in the text) commonly called LED (abbr. and), this technology has ceased to improve. And today, if you feel like it, you can light up your House with LED lights! But before you put all your light bulbs to recycling, see what are these LED lamps…
What is a LED lamp?
A LED or led Electro Luminescente is a component which has the ability to convert electrical energy into light. This physical phenomenon called electroluminescence.
These diodes have the advantage of being small. To be a lamp, several LEDS therefore gathered in a box whose aspect varies from the classic ovoid form, to the spot through the flame shape, ball, etc.
It would be more accurate to say “LED bulb” rather “than LED bulb… Especially since there are now several types of LED.
Classic LED and improved classic LED lamps
As classic LED bulbs, you know since the 60s because they are all witnesses to eve of your appliances or vintage table lamps. They look like all small bulbs at the end rounded or square and 3-10 mm in diameter.
Over the years, the light output has been improved a lot, these simple lights together on a suitable support became apart entire lamps. Like all the LEDS, they consume little energy and produce no heat. On the other hand, the angle of diffusion of the light beam remains focused in the order of 15 ° to 30 °. They are ideal to illuminate your favorite painting.
Classic LED lamps improved, as their name suggests, will give you greater brightness and a broadcast angle ranging up to 140 °. With them you can start to consider light the rooms of the House.
Lamps SMD LEDS or LED high power
The SMD LEDS comes in the form of a small white and flat square whose center is yellow. SMD means “Single Mounted Device” that is in good french “Component Monte on the Surface” is CMS. This component directly soldered to the circuit board allows to obtain a very flat LED.
These lamps consume even less than their classic sisters and have a light output greater (up to 40 lumens per LED) and especially more homogeneous. The lighting of more than 140 ° angle. They are more resistant to changes in voltage and heat which are two elements of fragility of LED bulbs.Though she even gives off a little heat that will dissipate toward the rear of the lamp.
They are classified according to their size: LED SMD 0805, 1210 SMD, SMD 3528 SMD 5050. So a LED 3528 made just 35 mm X 28 mm.
LED high-power (high power) and COB lamps
Take a SMD LEDS and increase its capabilities with a lens that multiplies its power and you will get a High-Power LED still light both in intensity and performance but which gives off a little more heat. Actually more the LED performance will be important, it will heat. In addition its diffusion angle is on average that 45 °, which limits its use for general lighting.
Now take several High-Power LED that you install on the same support and you get a LED COB. COB is an acronym for Chip On Board, literally “chip on board”. Of course, aren’t the dog chips but chips! In a lamp, they often come in the form of yellow sticks: these are all the chips or chips, welded to each side.
The LED technology continues to improve. But in the jungle of abbreviations, angles of diffusion, returns and light rendering, how do you choose the right lamp?
