WHAT IS LED TECHNOLOGY?
With a lifetime about 100.000 hours, LEDs have the advantage of a life span lasting over 35 years in case of an 8 hours use daily. Energy saving LEDs let infrastructural costs ranging from the fall of the cable sections used in infrastructure to the transformer power decrease. The fact that LED lighting kits do not heat and they are also sources of cold light, cooling systems are not charged with electricity. When the exchange of voltage problem in Turkey is taken into consideration, LED lighting kits operating up to a fall 150W without any loss of performance remove a great disadvantage on this matter. LEDs are solid- state semiconductor devices that convert electrical energy directly into light. Thermal sources of light such as flames and incandescent filaments emit light when heated, either by chemical reaction (flames) or electrical heating (filament lamps). LED (cold) generation of light leads to high efficiency, because most of the energy radiates within the visible spectrum. As LEDs are the solid- state devices, they can be extremely small and durable while providing longer lamp life than other sources do.
LED Lighting Systems
WHAT ARE THE ADVANTAGES & BENEFITS OF LED LIGHTING SYSTEMS?
In the following years, LED will be the technology that will replace light bulb. Due to the LEDs which have many appealing advantages like no heat dissipation, long life, alternative colors, true color feature and various places for applications, this technology can be used by everyone. Architectural designs have such a structure that the smallest details can be revealed as LED lighting components are used as small modules and in addition to this, they can serve properly because of their true color efficiencies. Moreover, these modules are also decorative components on their own.
What's so fantastic about LEDs ? Why all the fuss?
Switching to low energy, solid state lighting benefits the environment. LEDs consume far less energy than standard light bulbs, leading to greatly reduced energy costs. LEDs also require far less energy to manufacture than other light sources, reducing their environmental impact even further.
Despite their initial high price, the use of LED lighting can offer significant cost savings over time, not only in terms of reduced energy consumption, but maintenance as well. Because LEDs run on low current and low voltage and efficiently convert electricity into light, they require less energy than conventional light sources.
Improved Safety & Security.
The low heat and low voltages associated with LEDs make them a far safer source of light. The low operating voltage of LEDs eliminates sparks and qualify for UL low-wattage certification.
LED can be arranged in virtually an infinite number of configurations to create new design solutions. Lines, points, fields and curves of light are all possible. In addition LED are readily controllable and easily programmed to make subtle changes in color, color temperature and qualities of light. The intrinsically safe nature of LEDs, combined with their long term reliability and minute size, mean that they can be built into the fabric of almost any structure or object. Imagine a stairway, lit by its handrail; or a room illuminated by the furniture. With LEDs, anything can become a source of light and they offer designers and architects a lighting tool of unprecedented versatility.
With an expected lifespan of 50,000 to 100,000 hours (approximately six to 11 years of continuous use), LEDs last approximately 50 to 100 times longer than the typical incandescent bulb. Even in hostile conditions, the typical working life of an LED can be several tens of thousands of hours; most bulb filaments expire after just a couple of thousand hours and even compact fluorescent lamps come nowhere near the working life of LEDs. Also, LEDs don't suddenly burn out - they slowly fade over time, giving ample opportunity to plan replacements. Even at the end of its working life, an LED will still be giving some light.
A Range of Colors.
LED produce high purity colored light that can be mixed to create millions of colors - offering users a broad spectrum of choices. Stand-alone colors include near, blue, green, pink, yellow (amber), orange, red, warm white and white.
With their small size, LED can be used in places unreachable with conventional lighting. LED-based fixtures are smaller, resulting in applications that can be safely positioned inconspicuously, almost anywhere.
LEDs do not necessarily need an electrician for installation. They are rarely replaced.
Durability & Reliability.
The filament in a normal bulb is a very fragile object, easily broken by a sudden shock or "soft" drop. An LED is encased in virtually unbreakable high strength optical grade resin. There is no glass or filament to break, making LED light sources perfect for rugged or demanding environments, or installations where access is difficult. LEDs are extremely robust - resistant to shock, vibration, mechanical and thermal stresses, and vandalism. Assemblies can be completely sealed, making them waterproof, and are a suitable option for "hostile" environments like extreme cold or high humidity. For this reason they are used on cars and trucks, in airplane cockpits.
