Features of LED Light Bulbs

The LED bulb is a type of bulb used to light fixtures. But there are also other types of bulbs as:

  • incandescent bulb,
  • halogen,
  • neon,
  • low-energy bulb.

Features of LED Light Bulbs

LED bulb: simple operation

The recycling of the LED bulb is mandatory.

The LED (LED in French) means light emitting diode, that is to say “chip” of semiconductor:

  • the electron motion causes an emission of light according to the principle of electroluminescence,
  • its structure is simple and easy integration into an electrical circuit.

The LED bulb has no filament unlike incandescent bulbs: the heat emitted is much less.

An LED lamp is simply comprised of an LED chip mounted on a reflector base, a cathode (-) and an anode (+) and an epoxy glass which protects the diode.

It has a variable based on the type of bulb which was to:

Good to know : Some models are called power LED light higher in power. This power is limited because in consideration of their performance, they emit a lot of heat and can only work with a rather powerful cooling system (eg cooling fins) but bulky.

LED Bulb: various uses

LEDs are suitable for accent and task lighting, bedside lamp , spotlights but also mood lighting.

They are also places them outside the house for marking a path, or the value of massive development and can successfully contribute to the illumination of your pool.

LED: a light bulb designed for the design!

Very small, the LED bulb is integrated in products in elegant, discreet design and comes in different colors.

A special feature: it has a variable angle of diffusion. To you to decide if you want a wide illumination (open angle) or a 30 ° cone (closed angle), one more question to ask you!

LED lights are often provided with a dichroic reflector which has the effect of projecting the light forward and rearward heat.

LED bulb: a lifetime record

The life span of this type of bulb can reach 100,000 hours, she even beats fluorescent lamps.

Its security is due:

  • its resistance (no weakness even to repeated ignitions)
  • and operation when supplied with low voltage (few volts).

Other benefits:

  • very less electricity, it has a yield easily reaching 50-60 lm / W,
  • its intensity can vary, so use it with a dimmer is possible,
  • no electromagnetic field or radiation UV released, also no mercury (unlike CFLs).

LED Bulb: not suitable for rooms where children live

The LED spotlights emit a very blue light, and with a very high luminance. At high power, the light emitted by the LED is dazzling. In addition, its light spectrum is not suitable to young children.

For interior lighting, it should limit the light intensity perceived by not seeking a powerful lighting. In any case, do not put any LED bulb in a room where a child stays long (bedroom, kitchen).

LED: a high price but down

The price of the LED bulb is still quite high, even if it is down for some time:

  • from 12 € (12 V, 2 W spot)
  • up to 75 € (220 V, 7 W E27).

Its other disadvantages:

  • highly variable efficiency according to the power,
  • it has a light spectrum strongly bluish, where the risks mentioned by critics for a category of sensitive or with certain eye diseases,
  • need for a well-ventilated support (for power LED) because of the high heat emission.

Warning! Observe good indication of the manufacturer about the destination of the bulb and check that they can not cause burns.
