Why Use LED ?


Why use LEDs??

Innovation is revolutionizing the green world lighting industry with the LED Lamp.Thanks to its spectral recipe, LED concentrates its light where it is really needed by different mechanisms. As a result, you get high-quality lighting while using much less electricity compared to HPS and MH lamps, as well as a much longer lifespan!

Born from the latest discoveries and from the most up-to-date lighting technologies, the LEDS are the only one that offers the following features:

Energy Saving, Saving Money

1. Low power consumption
2. High luminous flux (80-130Lm/W)
3. Long life span: 50000hrs (last over 10 years if lighting 12hrs per day)
4. No maintenance cost: no additional ballasts or lights that require changing

Safety and Environment Friendly

1. Wide voltage range: 85V-265V
2. Turns on instantly without flickering
3. Runs cooler than traditional lights
4. Lack of UV/IR light radiation
5. Resistance to high temperature variations, humidity
6. It helps protect the environment and reduce CO2 emissions. LEDs give off 97% light, only 3% heat. A halogen light gives off 95% heat and only 5% of light.

Why do LEDs consume less energy?

The LED consumes less to generate light from a more efficient process. For example the incandescence is based on warming up a tungsten filament until it emits visible radiations. This process emits infrared radiations (heat) that is not useful. The LED is based on the electroluminescence, a phenomenon that does not emit infrared and by this it is more efficient.

How much can I save?

LEDs target less energy consumption between 40 & 80% off your monthly electrical bill. Savings vary depending on how many LEDs being installed or how many Halogen bulbs are being replaced.

What are LEDs?

LED is A light-emitting diode (LED) is a semiconductor light source. LEDs are small light sources that become illuminated by the movement of electrons through a semiconductor material.
Low-Powered LEDs
LEDs used to draw attention to something, such as an exit sign, a green power button on a computer, or a red blinking light on a video camera.

High-Powered LEDs

LEDs used to illuminate an area. LED lighting uses multiple illuminator LEDs inside a fixture to produce white light.

What is Solid-State Lighting?

LEDs are part of a family of lighting technologies called Solid-State lighting. This family also includes OLEDs (Organic Light Emitting Diodes). OLEDs (pronounced OH-leds) consist of sheets of carbon-based compounds that glow when a current is applied through transparent electrodes. While not yet market ready, OLEDs will function like a thin film on a wall or ceiling that illuminates a room. Like LEDs, OLED technology is advancing rapidly.
Solid-State lighting (SSL), most commonly seen in the form of Light Emitting Diodes (LEDs), has the potential to revolutionize the efficiency, appearance, and quality of lighting as we know it.

How are LED lighting products different from other lighting, like fluorescent or incandescent?

LED lighting is more efficient, durable, versatile and longer lasting than incandescent and fluorescents lighting. LEDs emit light in a specific direction, whereas an incandescent or fluorescent bulb emits light – and heat – in all directions.
LED lighting uses both light and energy more efficiently.

For example, an incandescent or compact fluorescent (CFL) bulb inside of a recessed can will waste about half of the light that it produces, while a recessed down light with LEDs only produces light where it’s needed – in the room below.
Incandescent bulbs create light by passing electricity through a metal filament until it becomes so hot that it glows. Incandescent bulbs release 90% of their energy as heat.

In a CFL, an electric current is driven through a tube containing gases. This reaction produces ultraviolet light that gets transformed into visible light by the fluorescent coating (called phosphor) on the inside of the tube. A CFL releases about 80% of its energy as heat.
LED lighting products use light emitting diodes to produce light very efficiently. The movement of electrons through a semiconductor material illuminates the tiny light sources we call LEDs. A small amount of heat is released backwards, into a heat sink, in a well-designed product; LEDs are basically cool to the touch.

Basic parts of LED lighting

LED lighting starts with a tiny chip (most commonly about one square millimeter) comprised of layers of semi-conducting material. LED packages may contain just one chip or multiple chips, mounted on heat-conducting material called a heat sink and usually enclosed in a lens. The resulting device, typically around 7 to 9 mm on a side, can be used separately or in arrays. LED devices are mounted on a circuit board, which can be programmed to include lighting controls such as dimming, light sensing and pre-set timing. The circuit board is mounted on another heat sink to manage the heat from all the LEDs in the array. The system is then encased in a lighting fixture, architectural structure, or even a ‘light bulb’ package.

How do I change the LED lights?

LED lights are designed take a minimum amount of time to install. Adapting to the formats of international sockets (E27, GU5.3, G13…) and working to 230VAC. In most cases the substitution is direct.

What is the colour temperature?

The colour temperature determines the colour of emission at the source. Depending on the type of work centers around the temperatures that are used. There are LEDs available in Cold White(~ 5500K), Warm White (~ 3000) and other colours such as blue, red, green, etc. The colours available are specified on the list of credits.

What does the term LUX mean?

LUX is the basic unit of measurement of the illumination. It measures the amount of light that arrives on a certain surface. It is a quotient between the beam of light that arrives at this surface between the actual light itself. Thus LUX is a determined point which varies from the distance of the beam of light. The further away it is and the wider the angle, the less the illumination.

What does the term LUMEN mean?

It is the unit of the luminance flow. It quantifies the amount of total light that leaves the light point. This magnitude considers the different sensitivity of the eye from the different frequencies. One is moderate in a spherical camera, where different mirrors reflect the light emitted in all directions towards a same sensor.

How tough is an LED light?

The average duration considered by the LED manufacturers is around 50,000 hours without losing more than 30% of the luminance flow. This duration is conditional to those that are used in lamps with a suitable heat dissipation.

Why is an LED light more expensive?

The LED of high power is a technology in constant development and with a complex process of manufacture. Its smaller present production with respect to the traditional illumination causes the price to be higher.
