[: en] In recent years, there are many major reference brands in the professional lighting market such as ETC, Claypaky or Ayrton, among others, which have opted for an R & D investment focused on performance, efficiency and LED technology . Undoubtedly, a bet that changes the concept of professional lighting and its energy efficiency.
We understand energy as the property that allows any physical object to perform a job, and we link it directly with the development of society. The world advances at breakneck speeds, and we are not aware of the amount of energy we waste daily. So when we talk about energy, we can not avoid talking about the importance of energy efficiency.
Energy efficiency aims to reduce energy consumption, in this way what is intended is to optimize resources and produce more, with less energy. In other words, It is not about saving light, but about better lighting with the lowest energy consumption possible. Through energy efficiency we seek to protect the environment, and for this we must reduce the consumption of energy used daily.
Advantages and disadvantages of energy efficiency
Currently, the only problem or drawback of energy efficiency is that it is still an option. However, this tends to change, and is that with the 2020 in the spotlight, European legislation requires saving an 20% in primary energy consumption since the buildings built as of the date are almost zero emission . And in order to achieve this goal, the European Directive of 2012 / 27 / EU establishes a common framework of measures for the promotion of energy efficiency.
In order to comply with the European Directive, grants and subsidies are a basic pillar for the promotion of savings and the reduction of CO2 emissions. In Spain, there is a public body whose objective is to improve the country's energy efficiency, and for its proper functioning it carries out dissemination, training, advisory and financial aid actions.
In 2017 IDAE, it has 4 help programs:
SME aid program and large industrial sector company: Its objective is that the industrial sector of small and medium companies perform works that improve their energy efficiency.
Aid Program for Energy Rehabilitation of Existing Buildings: Its objective is to improve the energy efficiency of existing buildings.
Energy efficiency is directly linked to saving electricity. Therefore, among the main regulations on energy efficiency and renewable energies are several laws and decrees that refer to lighting and efficient electricity.
There are already many countries and projects that are joining every day to a more responsible consumption of energy. And increasingly in the professional field. But although there is still some resistance in the use of LEDs in large venues, we must not forget that far from this debate, LED lighting can offer us many advantages over conventional lighting.
The LED devices represent a great economic saving, both for the low energy consumption and for the low maintenance costs.
An LED lamp consumes 8,9 times less than a traditional incandescent lamp. So the economic expenditure on energy is considerable. Its lower energy consumption directly translates into much lower installation costs, due to the smaller dimension of its wiring.
On the other hand, we have a technology with a much longer useful life. Which leads to great savings in expenses, where maintenance is very complicated or expensive, or even where the maintenance of changing luminaires or consumables are difficult to access.
The LED devices have a higher luminous efficiency than conventional luminaires, reaching up to 80% less than a traditional lamp cut-out.
Another great advantage is that it allows us to direct the light towards the desired area without losing part of the energy in beams of light in undesired directions, thus increasing uniformity and reducing the loss of energy.
A lot has been said about the issue of color in LED technology. The great advances and investment in the development of this technology, imminent entry into the professional field and design, offer a great technological capacity to obtain a large spectrum of color in its application in scenarios.
Thanks to the investment in R & D, the use of seven colors instead of the well-known RGBW, eliminates color barriers offering greater coverage in the execution of color. In addition, LED technology offers us a result of the purest, clearest and most intense color.
They do not emit heat
Another great advantage of LED lamps is that they do not emit heat, which a priori may seem a fact without great relevance. But it offers not only a better performance of the device, but a saving in other items such as the consumption of air conditioners in the room.
On the other hand, in the theatrical field the cuts of ETC Source Four LED, allow a saving in the purchase gobos since they allow the use of gobos printed on acetate paper, which are more economical and are not affected by heat.
LED lamps are a source of ecological light, since they do not generate ultraviolet or infrared light and do not contain toxic products. In addition, these lamps produce a loss almost no heat and save energy, which greatly helps the environment and reduce CO2 emissions.
The major brands of professional lighting know the incipient growth of the need and demand for devices that are in line with smart consumption, and with a performance that offers the quality of professional lighting in shows and scenic spaces. This was what we saw last September in London during the PLASA fair, in which LED technology was undoubtedly the main protagonist of the conference. All the most representative brands of the world of lighting came with some surprise in the field of LED technology.
ETC was one of the pioneers in working LED technology with the development of its seven-color system, allowing greater coverage of the color spectrum, without losing the charm of the light that gives identity to the theater. Your range Source Four LED, is one of the most revolutionary products of the well-known American brand. This range is an evolution to LED of the traditional indispensable of any theater, the cuts Source Four. This adaptation is perfectly studied to produce a light source that adapts to the needs of the great professional designers, but with all the characteristics of LED lamps.
Within the LED range, we can find:
This focus is mainly characterized by its mix system of x7 colors, extending the usual range of three colors: blue, green and red, to seven with colors such as lime, cyan and amber. Thus offering a wide range of color, which achieves a representation of high intensity whites and soft and bright colors worthy of the theater.
Tungsten + Daylight
These spotlights are characterized by their color temperature. Its two models, Tungsten, warm light and Daylight, cold light, make them perfect for sets and spaces where they work with both warm and cold light. The Tungsten is perfect for simulating tungsten lights, these bulbs allow their use together with other sources of tungsten light or use them separately. While the Daylight gives a cooler quality of light.
The main feature of this focus is that it allows you to configure the mode and time of the flickeo, which makes it perfect for use on television sets.
For its part, Claypaky works in the line of LED technology with its Axcor Profile 900. With its mechanized blades, a power of 900 watts and a luminous flux of 24.000 output lumens, it works with a system of dichroic filters for the creation of colors, offering a uniform and unique color.
Among other large companies, such as Ayrton or Chauvet Professional, LED technology becomes synonymous with development and technology, offering new design and innovation opportunities for professionals in the world of professional lighting.
Another great example of brands that rise to the development of LED luminaires is GDS with his light bulbs ArcSystem of LEDs, created especially for uses such as the lighting of theaters in theatrical or theatrical spaces, offices or stages.
The GDS luminaires stand out for their high CRI and their regulation of the light flow through dimmer, achieving the desired light effect.
There are many examples of spaces that have applied this technology, as in Brighton Dome, where an old stable turned into a spectacular theater has renovated all the living room lamps using this new form of LED lighting. thanks to the GDS bulbs they preserve the aesthetics and the original luxury of the room, and at the same time they reduce costs with an energy saving and maintenance.
Undoubtedly, LED lighting is the great bet within the professional lighting market, and more and more major brands are joining this challenge as the indispensable ETC, Claypaky, Ayrton, Chauvet, GDS, among others. They are the ones who mark the reference within an increasingly changing market and more linked to the evolution of new technologies in professional fields.
At the same time, the reconciliation between saving and design is added, where LED devices take the reins of the market for their numerous advantages such as energy saving, light efficiency, color quality, or the fact that they are a source of light more ecological. [:]
