WHY YOU CHOOSE DYUTHI LED?

 

WORLD BEHIND LED LIGHTNING..

 The Household lighting cost typically accounts for 10% of the electric bill. Changing the light bulbs effectively can reduce the long-term energy costs significantly. The popularity of the fluorescent light can be judged by the fact that it accounts for a greater amount of light produced on our planet than any other light source. It secure this dominating position by the 1970s and today, it approximately accounts for about 80% of the world's artificial light. It is manufactured in almost any shade of white as well as colored versions. It also has an advantage of a low system cost, its lifetime is very long, it is fully dimmable and is easy to use, and above all it achieves high luminous efficiencies to yield a low cost of operation. In 1980, its position was further strengthened by the introduction of the compact fluorescent lamp. The traditional incandescent bulbs usually convert most of their energy into heat instead of light, leading to wastage of electricity on unnecessary warmth. Compact fluorescent lights (CFLs) and light emitting diodes (LEDs) on the other hand, convert most of their energy into light. But the frequent use of CFLs can shorten their life span. LEDs are designed to last longer than the average incandescent bulb and CFL, reducing both energy and replacement costs and increasing longevity. LED bulbs consume up to 80 percent less energy than their incandescent counterparts and 20 percent less than CFLs. They can last up to 25 times longer than CFLS and incandescent.

ABOUT THE EXISTING BULBS 

1. FLUORESCENT LAMPS

   The fluorescent light bulb was first commercially introduced in 1939, however, it had been on a developed stage for over 80 years, and the idea of using fluorescence as one of the lighting source had existed for even longer. It is easy to understand the charm of fluorescence if taken as a light source.  

DISADVANTAGES   

• Highly toxic Mercury vapour is of high concern.
• Reduction in light output in cold areas.
• Difficult in handling due to its length
• Sensitivity to ambient temperature

     2.  COMPACT FLUORESCENT LAMPS

   As an alternative for light bulb, CFL bulbs were developed. CFLs are a miniature version of the common fluorescent light, glowing phosphor gas by using an electric current. Earlier the CFLs used magnetic ballasts which usually results into delay or flicker when turned on. Whereas, the most new CFLs use electronic ballasts. On comparing with incandescent bulbs, CFLs are approximately four times as efficient i.e. a 25 Watt CFL will have the same light output as a 100 Watt incandescent bulb. They also possesses high longevity i.e. 10 times longer, meaning that the life of a standard CFL is comparable to 10 incandescent bulbs. But, a CFL gives off light that looks just like a standard incandescent. 

DISADVANTAGES   

• Freequent use of CFL, also known as flipping can shorten their life span.  
• Low temperature can cause the CFLs to perform with lower light levels, hence reducing their utility.  
• CFL contains mercury, a toxic substance. But, it does not pose a health threat unless the bulb is broken.  
• Problem with humming noise and flickering light have largely been addressed by improvements in CFL technology (CFLs using magnetic ballasts

 LED BULBS

 An LED lamp is a light emitting diode product which is assembled into a lamp for use in lighting fixtures. LED lamps have a lifespan and electrical efficiency which are several times longer than incandescent lamps, and significantly more efficient than most fluorescent lamps, with some chips able to emit more than 300 lumens per watt. The LED lamp market is projected to grow by more than twelve-fold over the next decade, from $2 billion in the beginning of 2014 to $25 billion in 2023, a compound annual growth rate of 25%. As of 2016, LEDs use only about 10% of the energy an incandescent lamp requires.
 Like incandescent lamps and unlike most fluorescent lamps, LEDs come to full brightness without need for a warm-up time. The life of fluorescent lighting is also reduced by frequent switching on and off. The initial cost of LED dye and packaging materials reduces light output to some extent over time.
 Some LED lamps are made to be a directly compatible drop-in replacement for incandescent or fluorescent lamps. An LED lamp packaging may show the lumen output, power consumption in watts, color temperature in Kelvins or description, operating temperature range and sometimes the equivalent wattage of an incandescent lamp of similar luminous output.
 Most LEDs do not emit light in all directions, and their directional characteristics affect the design of lamps, although omnidirectional lamps which radiate light over 360 degree angle are becoming more common. The light output of single LED is less than that of incandescent and compact fluorescent lamps; in most applications multiple LEDs are used to form a lamp, although high-power versions are becoming available.
 LED chips need controlled direct current electrical power; an appropriate circuit is required to convert alternating current from the supply to the regulated low voltage direct current used by the LEDs.
 LEDs are known as tiny lights which are produced by moving electrons in a semi- conductor. Due to the absence of burning gas or filaments, LEDs are considered more durable and produce very little amount of heat. Since, LEDs have an advantage of small size, they are resistant to weather and can also be water-proofed for extreme weather conditions.  
LEDs are solid state semiconductor devices. LED units are usually small, typically 5mm.

 BENEFITS OF LED LIGHTING 

1. LONG LIFE 

 Long life time stands out as the number one benefit of LED lights. LED bulbs and diodes have an outstanding operational life time expectation up to 100,000 hours. This is 11 years of continuous operation, or 22 years of 50% operation. If you leave on the LED fixture of 8h per day it would take around 20 years before you’d have to replace the LED bulb.
 LED’s are different to standard lighting. They don’t really burn out and stop working like a standard light, moreover the lighting diodes emit lower output levels over a very long period of time and become less bright.

2. ENERGY EFFICIENT 

 Today’s most efficient way of illumination and lighting, with an estimated energy efficiency of 80%-90% when compared to traditional lighting and conventional light bulbs. This means that about 80% of the electrical energy is converted to light, while 20% of energy is lost and converted into other forms of energy such as heat.  With traditional incandescent light bulbs who operate at 20% energy efficiency only, a 80% of the electricity is lost as heat.

  3. ECOLOGICALLY FRIENDLY  

LED lights are free of toxic chemicals. Most conventional fluorescent lighting bulbs contain a multitude of materials like e. g mercury that are dangerous for the environment.  LED lights contain no toxic materials and are 100% recyclable, and will help to reduce carbon footprint by up to a third. The long operational life time span means also that one LED light bulb can save material and production of 25 incandescent light bulbs. A big step towards a greener future.  

4. DURABLE QUALITY  

LEDs are extremely durable and built with sturdy components that are highly rugged and can withstand even the roughest conditions.  Because LED lights are resistant to shock, vibrations and external impacts, they make great outdoor lighting systems for rough conditions and exposure to weather, wind, rain or external vandalism, traffic related public exposure and construction or manufacturing sites. 

5. 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 as in museums, art galleries, archeological sites etc.

 6. DESIGN FLEXIBILITY  

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 mind.   LED mood illumination is already being used in airplanes, classrooms and many more locations and we can expect to see a lot more in the next few years. 

7. 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. 

8. LIGHT DISPERCEMENT 

 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.

 9. 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 mission. In contrast, traditional lighting may take several seconds to reach full brightness, and frequent on/off switching does drastically reduce operational life expectancy. 

10. LOW VOLTAGE  

 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.
