REPLACE THE HALOGEN BULBS WITH LEDS

LED LIGHTS

Replacing halogen or incandescent lamps with LED LIGHTS represents a very useful solution that allows for obtaining different advantages in terms of energy saving.
First and foremost, light bulbs are electrical devices that produce light and are classified according to voltage (V) and power absorbed by the network, expressed in Watts (W). The lumens instead express the degree of brightness emitted by the lamp.
The ratio between the visible light energy emitted and the absorbed electrical energy is defined as luminous efficiency. Part of the energy produced is lost, dissipated as heat or emitted light not visible to the human eye (e.g. infrared or ultraviolet light).
Based on the type of technology used, we mainly distinguish 4 types of bulbs: incandescent, fluorescent, halogen and LED.
We see the main characteristics of the various types of lamps and why it is good to replace halogen lamps with LEDs.

Incandescent bulbs

They produce light by bringing to incandescence, or at a temperature of 2700K, a metallic tungsten filament, through which the electric current passes, positioned in a quartz or glass ampoule, saturated with inert gases at low pressure, which has the purpose of avoiding the oxidation and limit evaporation.
With this type of technology, only 5% of the energy produced is transformed into light, while the remaining 95% is given off in the form of heat. One of their variants is represented by halogen bulbs.

Halogen bulbs

The halogen gas inside the bulb makes it possible to reach a temperature of 3000K, which increases its luminous efficiency compared to classic incandescent bulbs.
Taking advantage of the tungsten halide, which is the evaporated tungsten that reacts with the halogen gas, the so-called halogen cycle is created, which doubles the average life of the halogen bulb compared to the traditional one.

Fluorescent bulbs

In this case, the light emission is indirect because the issue is not the gas but a fluorescent material. Unlike incandescent bulbs, fluorescent bulbs are connected to the network through an inductor that limits the supply current and creates an overvoltage that facilitates ignition. This device extends the time to reach full brightness.

LED bulbs

They are optoelectronic devices that exploit the optical properties of semiconductor materials to produce photons through spontaneous emission. The LEDs have a very high luminous efficiency and immediately release all their luminous capacity.

Why replace halogen lamps with LEDs?

The LED lamps are first of all endowed with a particular resistance in the time that allows avoiding continuous replacements.
Unlike traditional lighting means, such as incandescent halogen lamps that tend to burn out after a certain number of hours of use or ignition, those LEDs are characterized by longer duration, able to offer a level of use truly high.
Obviously, even the type of lighting with LED lamps is superior to the classic type: note also that these particular lamps require little time to be able to illuminate at the highest levels without overheating, as happens with traditional bulbs.

Replace the halogen lamps with the LEDs: a saving choice

On the savings side, it must be emphasized that although LED lamps have a slightly higher cost, this expense appears to be an investment, given that consumption is much lower than that of classic light bulbs.
Let's take a small example: a traditional 100 W lamp corresponds to an 18 W LED lamp which, over the course of a month, will save about € 35 on the electricity bill compared to the classic light bulb.
A 53 W halogen lamp corresponds to a 15 W LED, and even in this case, the saving is around € 20 per month.
Many examples could be made, but the concept remains the same: with LED lamps it is possible to obtain a great saving on the cost of the electricity bill.

Lumen Watt Equivalence

In traditional bulbs the lumen watt ratio was constant. With the LED technology, on the other hand, the two values differed greatly from each other, with a considerable reduction in watts (thus achieving lower consumption) and an increase in lumens (luminous efficiency).

OFFICE AND COMMERCIAL LIGHTING WITH LEDS

Image
The choice for office and commercial lighting relative to an office can be really optimal, for many reasons: LED lighting, on the other hand, is the last frontier of this sector, so it is not surprising that it is so widely used in work contexts. Office lighting: the regulation The lighting of an office is governed by the European standard EN 12464-1, dedicated precisely to lighting concerning workplaces. In this standard, various aspects concerning office lighting are defined, such as luminance distribution, uniformity, light direction, control of natural light, color rendering index. In its most recent updates, moreover, EN 12464-1 has also introduced other aspects that must necessarily be considered when setting up lighting solutions for workplaces, for example, the brightness level of video terminals. Without going very specifically, it can be stated without any doubt that the LED lights are a genuine first choice to provide lighting for an office in full compliance...

Missing less and less from the new edition of Elettromondo, the event dedicated to electrical equipment and more generally to electricity. One of the innovations awaits the focus on conscious innovation and the evolution of technology in the sector. It's called Elettromondo and is one of the most awaited events dedicated specifically to the electricity sector in Italy, a highly qualified event for operators in the sector able to attract almost 10 thousand people over the weekend of meetings. And after a 2016 edition that set a new record for visitors, preparations are already underway for this year at the Rimini exhibition center. The electrical equipment fair.  More than 150 brands are involved in this event annually, selected among the most qualified producers in the sector, and in the two days of the event they give life to a wide range of innovative products and solutions, intercepting and anticipating industry trends: from  air conditioning  and heating to ele...
