Led advantages

Lower consumption. It has the lowest consumption of all existing lighting technologies, often reaching only 10% of the consumption compared to other conventional lighting sources.

Profitability. It is the most cost-effective lighting system availabel in the market.

Cold source of light. LED lighting emits no heat, avoiding effects of overheating or burning over the illuminated objects.

Zero Maintenance. The LED does not melt. It lasts for more than 80,000 hours and requires no maintenance. An incandescent bulb has 1,000 hours of life and a fluorescent numbers approximately 9,000. The 60,000 hours o fan LED reduces maintenance costs and periodic replacement of lamps. Its solid state also allows them to be exposed to extreme temperatures and vibrating environments.

Environment. It is cleaner and more sustainable. Installing LED, you contribute to the conservation of our environment. The LED light source is more environmentally friendly. Unlike fluorescent light sources, LEDs contain no mercury or other contaminants. The removal of mercury lighting system will allow you to meet increasingly strict environmental regulations. Similarly, the lowest consumption and maintenance contribute to energy savings.

Durability and high luminous flux. Unlike conventional light sources, LEDs do not fail or merge. Instead, the performance of LEDs degrades slowly over their life and on average they gradually lose a 30% of their intensity after 60,000 hours of use. Should be lit 12 hours a day, this period would result in a period of 11 years.

Energy Efficiency. The LEDs are more efficient than incandescent and halogen bulbs. They emit more than 90 lumens per watt and emit directional light, making them more efficient than other light sources including fluorescent. The figure is much higher when compared to halogen bulbs, which emit 20 lumens per watt. In addition, issuance of concentrated beams of energy ensures the profit in energy use versus the waste that involves the emission of scattered light, together with the use of bright colors without filters or gels.

Small size. LEDs are much smaller than conventional light sources, which has enabled a radical change in lighting design. Now, the light source can be hidden completely and create a magical effect when the luminaire is turned on. The flexibility of LEDs offers a world of possibilities and innovative solutions never imagined before.

More color. LEDs require no filters to create color, which makes the colors saturated and no waste of light. The red, green and dark blue colors can be produced directly from the LED, monochromatically. When using filters, we block unwanted elements of white light and energy is wasted. One example is the case of traffic lights, where a 12W LED red replaced a 150W bulb. The primary color LEDs can also be used to create RGB systems forming a wide range of colors.

Direct light. The light emitted by a LED is directional. Conventional light sources emit light in all directions and use reflectors to direct the beam toward the object to be illuminated. Each time the beam is reflected, it loses 40 to 60% of intensity, which means that in some cases it is lost more than half of the light to finally reach the desired direction. The natural directionality of LEDs results in an efficiency of 80 to 90%, so they require less total lumens to provide the same level of illumination.

Sturdiness. LEDs are solid state devices with no moving parts or filaments. Thus, the LEDs can be operated in hazardous environments including those in which they experience high vibration or strong impact. No risk of contamination, disruption, destruction or escape as their nature makes them extremely strong and durable. Moreover, many light sources are not well suited to cold environments, meancwhile LEDs withstand environmental conditions of -40 º C, simplifying design and reducing costs for specific applications.

Dimmable without discoloration. LEDs are fully adjustable without changing or sacrificing their properties. Therefore, the change in light intensity that does not vary the color temperature of the LED.

Cold light source. Conventional light sources contain ultraviolet radiation. Radiation can damage some materials, causing color changes or degradation. For the illumination of delicate objects, such as it happens in museums, LEDs are the ideal solution. The low heat generation of LEDs also makes them capable of being installed in areas sensitive to heat, leading to halogen sources to be replaced by LEDs in areas in which they had created security problems because of excessive heat.

What is an led and how does it work?

LEDs are basically small diodes that produce light when an electric current passes through the semiconductor material that they are made of. It is a strong element of great durability and strength and, unlike a conventional light bulb, it has no resistance or glass to break or burn.

A diode is the simplest semiconductor device existing. It is basically a semiconductor material composed of a material of poor conductivity that has been added “impurities”. This process is known as doping, and the impurities added are only atoms of another element, modifying the conduction properties of the material. For LEDs this material is typically aluminum gallium arsenide. In the aluminum gallium arsenide pure, all atoms are bonded together perfectly, leaving no free electrons to produce an electrical current. When the material is doped, it is amended by adding balance free electrons (negative charges) or holes (positive charges). Depending on the material that is added, it changes its conductivity properties and defines the type of semiconductor that is being created.

How do i create the colors with leds?

The colors are created by the LED itself without using gels or filters. The chemical composition of semiconductor materials within the LED define the color of light produced,and the emitted light is monochromatic (single wavelength). There are LEDs in all colors: red, green, blue, yellow, warm white and cool white. A white LED is actually a blue LED with a special phosphor coating inside the blue LED structure that converts light into white light. This is the reason why many LEDs emit a very cool color of light, usually in the region of 6,500 ° K. A warm white LED using an innovative new technology of coating of red phosphorus and the incorporation of white-emitting phosphors that give the appearance of a warm white color in the region ty.

What is lumen?

Lumen is amount of light emitted from light source. According to Wikipedia, "If a light source emits one candela of luminous intensity into a solid angle of one steradian, the total luminous flux emitted into that solid angle is one lumen. Alternatively, an isotropic one-candela light source emits a total luminous flux of exactly 4π lumens. The lumen can be thought of casually as a measure of the total amount of visible light emitted." For example, a standard 100 Watt incandescent bulb emits about 1500 lumen.

What is Lux?

Lux is lumen per square meter. The difference between the lux and the lumen is that the lux takes into account the area over which the luminous flux is spread. 1000 lumens, concentrated into an area of one square meter, lights up that square meter with an illuminance of 1000 lux. The same 1000 lumens, spread out over ten square meters, produces a dimmer illuminance of only 100 lux.

How do we connect led installations?

The installation of LED lighting is similar to conventional lighting fixtures. Luminaires must be connected to transformers or power supplies.
Traditionally, low power LEDs are fed at a constant voltage with a resistor that regulates the flow of each LED. In the case of high power LEDs, feeding is more sophisticated. A typical 1.2 W LED is regulated to a constant current of 350mA. If there is a string of LEDs, they must be connected in series. The 350mA is provided by power supplies called drivers.

How do leds compare to other light sources?

Halogen lighting. There are multiple formats and powers in halogen lighting. The most typical is the 50 watt bulb. Their main problem is their limited life span and high consumption, which carries a high level of maintenance costs and replacement bulbs. Its effectiveness is poor, close to 20 lumens per watt, but their power is much greater than that of the LEDs. Taking into account the development of technology, LEDs are already an alternative. Chromatic benefits are good, at the same level as warm white LEDs to 90 IRC. Other problems include the high temperatures reached in operation making them unsuitable for use in certain areas.

Fluorescent lamps. Have a high level of light output and efficiency near 80 to 90 lumens, like LEDs. The halo of LED light is directional whereas the fluorescent light is emitted omni-directionally. Of all the light emitted, 66% is not directed at the front of the lamp. It is difficult to compare the result considering that the LED is 66% more efficient. Fluorescents are appropriate for embedded linear applications. Their life expectancy is about 9,000 hours compared to 60,000 of the LEDs. Its color rendering index is quite high, 90 IRC. 3200 º.

What is the typical emission of a led light when it becomes useful?

A 1,2W LED achieves efficiencies up to 90 lumens for white LEDs and somewhat lower for other shades. A general myth is that a three-watt LED is brighter than one watt. Sometimes this is not true and to be completely reliable it is necessary to take into account the individual LED luminous efficiency, which depends on the make and model used in the LED luminaire.

What is the average life expectancy?

Life expectancy is 60,000 hours. However, the average life is higher, but once reached this period the LED brightness is progressively reduced by 30% of its original value. LED is likely to continue to operate much Langer. Unlike the conventional light bulb, do not suddenly stop working.

What is your consumption of energy/power?

The consumption depends on the type of LEDs used. As a guide, using LEDs of 1 watt of power, power consumption is 1.2 watt per LED. The drivers have an efficiency of 85% or so, so that the actual energy consumption is about 1.4 watt per LED. For this reason and for safety it is recommended to leave a margin of 20% higher than their theoretical load. For example in a plant with 10 LEDs of 1,2W, we can calculate the actual consumption as follows: [10 x 1.2 W] / 85% = 14.2 W.

What is irc, and means for leds?

IRC is the color rendering index. It measures the quality of reproduction of natural colors depending on the source of light. A light source with an IRC of 100 means that all colors appear exactly as expected under normal lighting conditions. IRC 100 is provided by the sun. The warm white LED of about 90 IRC, which provides excellent color perception. Currently, LEDs reach a development of an IRC 95.

What is the kelvin color temperature?

Color temperature of a light source is a way to compare the whiteness of the light emitted. A lower color temperature (typically 3000 º K) gives a warm white color. The higher color temperature, the light seems colder. Cool white has a temperature of 4200 º K or even 6500 ° K. Color temperature is measured in degrees Kelvin (K). This relates to the color of light, that would be produced by a tungsten filament lamp with the filament in the color temperature using the Kelvin temperature scale.

Do led’s heat up? Thermal factors

The warmer a LED becomes, the shorter its life will be. The LED designs that taking into account these factors, they save the lives of its products for over 50,000 hours. The high power LED will get extremely warm if it is not built a structure that allows heat dissipation. High temperature could cause rapid degradation of LEDs. The LED luminaries with a sufficient dissipation system to ensure proper heat distribution and temperature maintenance. The temperature of an LED installation should never be hot enough to cause burns.

Does the led change its color over time?

Every light source suffers a slight color change over time. Typically, if a bulb is replaced, it will appear that has a different color than the other bulbs that have placed time. In the case of LED, the color change is prevented by the proper thermal management components. The decrease in the intensity of light in a conventional light source may cause the change of color temperature given [the incandescent and halogen lamps take on a reddish hue when reduced light intensity]. This alteration does not suffer because LEDs special regulatory systems.

Is it possible to regulate the intensity of the led?

The LEDs can be regulated by DMX systems for individual control of each driver, or with traditional controllers that are used for conventional light sources, in an economical and efficient way.
