Environmental impact, reduction in fuel consumption and increased life of the product are the main advantages of the described promotional campaign made in favor of LED lamps.
This technology, applied to lighting, It appeared on the market in the last century and is set to become, thanks to the low environmental impact characteristics, the instrument of excellence for the illumination.

A large part of the electricity used in the world is used for lighting.
In order to limit fuel consumption and reduce operating expenses, states link on LED technology. Data in hand, this technology promises a life of the upper bulb 30.000 hours or a frequency parts 10 times lower than that of incandescent lamps.
The LED lamps, They are free from sodium, mercury and fluorescent substances, that they are harmful and unhealthy, do not contain the filament nor the typical gas of fluorescent light bulbs or halogen lamps using electronic components and a total of less polluting.
The LED lighting is a product that has advantages on several fronts.
We are confident that the technology developed for this sector has reached the point of full maturity?
We have gathered here some observations.

The actual efficiency of the LED light bulb is given by various factors:
• the quality of LED technology;
• the goodness of the design of its thermal structure;
• the effectiveness of the current transformer;
• the efficiency of the optical instrument used.

Unfortunately, there are on the market LED bulbs that produce low-quality light and the duration of which does not correspond to what the manufacturer. Products of this kind may be the result of poor research and dedication of the manufacturing or use of outdated technologies.

Some technical details

To understand the reason for this difference between the promised results and those retained have to go back a few years:
between 2010 and the 2011 system prices in chip and plastic packages, prodotti per grandi schermi a LED, It suffered a sharp fall in production saturation.
The low prices of the members favored the use of this technology in lighting.

These LEDs are reused have been used for the low illumination and average power suited to domestic environments.

La polyphthalamide, shorter PPA, It is a thermoplastic resin capable of withstanding high temperatures, which is located inside the LED bulb.
The resin receives a considerable amount of reflected light from the white light surfaces of the package cavity in which are located the LED chips.
The constant of the plastic package lighting ago discolor the white surfaces of the bulb, while the blue photons emitted by the LED chip discolor the surface of the PPA package that starts to absorb the light with consequent depreciation of the luminous flux maintenance.

LED assembled

Lower the cost of products using unsuitable components (like the thought of technology for the product LED TV) or low quality is not the solution to spread massively product.
The risk, as evidenced, It is to market a product that runs the reliability and performance that disregards the promise.

Unlike the low-power LED and medium mounted on plastic packages PPA, the high-power LEDs that mount on ceramic base manage to have high performance and to maintain over time the initial luminous flux, color stability, ensuring energy saving and much underlined maintenance.

E 'must then optimize the technology used by switching to the disposal of LED plastic packages PPA to those mounted on ceramic looking pero' to contain the costs arising from the different components and thus making them accessible to the consumer.

A second interesting point on the optimization of tencologia LED is given by the design of the structure goodness in which it is placed.
The technology inside the bulb must in fact be preserved from high temperatures produced during operation. Here then, to ensure proper functionality, product design takes on a least as important as the technology.
The LED lamps in operation are warm to the touch (about half of the heat produced by an incandescent bulb). The LED bulb of the bulb is in fact the part responsible for the dispersion of the heat produced while the heatsink, Another important element, It allows to maintain the power supply and electronics as fresh as possible.

When the size of the electronic components go hand in hand with the design of the product you have a proper management of airflow and resulting in a better yield of light, stability of the electronic components, durability and effective savings.
It is not always easy to find the correct proportions.

Then there is at least one other case in which LED technology has failed to emerge as promised: It is the case of the halogen bulb. It used very often in homes and shops, this type of lighting had the advantage of producing an intense light while occupying a very small space, It reached very high temperatures of normal operation and it was able to dissipate as much heat even with small bulbs.
Current LED products can not replace this category of their product for a problem related to heat dissipation.
The electronic circuits, typical of LED technology, must remain at lower temperatures and consequently can not dissipate the same heat in a reduced volume and would not exceed the electrical safety testing.
Only a confirmation yet another aspect of the fact that there is still much room for research and development of new products.
