The advantages of LED
LED (Light Emitting Diodes) is the newest and most exciting technological advance in the lighting industry, which appeared relatively recently and gained popularity in our market because of its advantages – high quality illumination, long life and endurance – Light sources based on LED has up to 20 times longer service life than fluorescent or incandescent lamps.
Light-emitting diodes are an essential element used in electronics for many years, but only recently they gained its popularity due to high power LEDs, giving light strong enough to be used as substitutes for mercury fluorescent lamps, incandescent lamps or so called energy saving fluorescent bulbs.
At this moment, there are LED sources and modules available on the market, which are strong enough to be used as infrastructure lighting such as street or park lighting, and even architecture lighting of office buildings, stadiums and bridges. They also prove to be useful as a primary source of light in production plants, warehouses and office spaces.
LED lights are up to 80% more efficient than traditional lighting such as fluorescent and incandescent lights. 95% of the energy in LEDs is converted into light and only 5% is wasted as heat. This is compared to fluorescent lights which convert 95% of energy to heat and only 5% into light! LED lights also draw much less power than traditional lighting; a typical 84 watt fluorescent can be replaced by a 36 watt LED to give the same level of light. Less energy use reduces the demand from power plants and decreases greenhouse gas emissions.
LEDs used in this type of lighting have a high work efficiency and thus may run for up to 11 years compared to energy saving lamps with service life less than a year. For example, LEDs operating 8 hours per day will last for about 20 years of service life, and only after this period, we will be forced to replace the light source for new one. In addition, frequent switching on and off has no negative impact on the service life, while it has such impact in case of an older type o lighting.
No Toxic Elements
LED lights contain no toxic elements. Most offices currently use fluorescent strip lights which contain noxious chemicals such as mercury. This will contaminate the environment when disposed of in landfill waste. Disposal has to be arranged through a registered waste carrier so switching to LED avoids the cost and time implications required for compliant disposal – and helps to protect the environment from further toxic waste. LED are 100% recyclable, what helps to reduce carbon dioxide emissions. They contain chemical compounds responsible for the color of its light (phosphor), which are not harmful to the environment.
Zero UV Emissions
LED illumination produces little infrared light and close to no UV emissions. Because of this, LED lighting is highly suitable not only for goods and materials that are sensitive to heat due to the benefit of little radiated heat emission, but also for illumination of UV sensitive objects or materials such a in museums, art galleries, archeological sites etc.
In LED technology, we are able to obtain each illumination light color. Basic colors are white, red, green and blue, but with today’s technology, progress is so advanced that we can get any color. Every individual LED RGB system has three sections, each of which gives a different color from the RGB palette color – red, green, blue.
LEDs can be combined in any shape to produce highly efficient illumination. Individual LEDs can be dimmed, resulting in a dynamic control of light, color and distribution. Well-designed LED illumination systems can achieve fantastic lighting effects, not only for the eye but also for the mood and the mind: LED mood illumination is already being used in airplanes, classrooms and many more locations and we can expect to see a lot more LED mood illumination in our daily lives within the next few years.
Operational in Extremely Cold or Hot Temperatures
LED are ideal for operation under cold and low outdoor temperature settings. For fluorescent lamps, low temperatures may affect operation and present a challenge, but LED illumination operates well also in cold settings, such as for outdoor winter settings, freezer rooms etc.
LED is designed to focus its light and can be directed to a specific location without the use of an external reflector, achieving a higher application efficiency than conventional lighting. Well-designed LED illumination systems are able to deliver light more efficiently to the desired location.
Instant Lighting & Frequent Switching
LED lights brighten up immediately and when powered on, which has great advantages for infrastructure projects such as e.g traffic and signal lights. Also, LED lights can switched off and on frequently and without affecting the LED’s lifetime or light emission. In contrast, traditional lighting may take several seconds to reach full brightness, and frequent on/off switching does drastically reduce operational life expectancy.
A low-voltage power supply is sufficient for LED illumination. This makes it easy to use LED lighting also in outdoor settings, by connecting an external solar-energy source and is a big advantage when it comes to using LED technology in remote or rural areas.
