The inherent features of LED decide it to be the best alternative to conventional light source, and provide a wide range of application.
Small size: A LED is essentially a tiny chip ,about 4.5mm, encapsulated in an epoxy resin enclosure, so it can be extremely small and light.
Low Power Consumption: Generally a LED is [...]
As we all know that the future of energy efficient lighting is LED. Not only are LED’s environmentally friendly, the light represents a true white light. A recent press release printed in the Village News on ways to cut energy expenditures missed the mark completely.
Although it is true that CFL bulbs do save energy, they [...]
Full-color LED video display screen has become popular in recent years for various applications such as indoor/outdoor commercial advertisement, stadium billboards, traffic message signs…etc. Thanks to the evolution of LED technology which enables lower cost, higher luminance, uniform wave-length and better efficacy LEDs available, the LED display screen makers are able to build high quality [...]
LED fluorescent lamp is the newest product line in the fluorescent family and is considered to be the final replacement for traditional fluorescent lamp. It is made up of white LED chip modules. Provided with the advantages of long life-span, radiation-free, energy saving, environmental friendly and stroboflash-free, LED fluorescent lamp is superior to other kinds [...]
Scientists are developing solid-state light devices, made of light emitting diodes (LEDs), to replace the energy-wasting light bulb.
LED Advantages
Energy consumption: In an application such as a traffic signal, LEDs use 92 percent less energy.
Light production: LEDs produce more lumens per watt than an incandescent bulb. A single watt of an incandescent produces 11 to 13 [...]
LED is made up of a very small chip packaged in the epoxy resin. Generally, the operating voltage is 2-3.6V and the operating current is 0.02-0.03A. Traditional incandescent lamp emits light depending on tungsten filament, and the power-saving lamp depends on tricolor powder. Different from these two kinds of lamps, LED emits light through electric [...]
We’ve likely all experienced the bothersome inconvenience of having to change a light bulb located in a hard-to-reach place. Maybe a lofty porch light burns out, or a chandelier bulb dies. These can be difficult to get to, and many times they are lights that are left on for many hours throughout the day, so [...]
Unlike conventional incandescent lamps which need to convert the electricity into thermal energy first and then to light, LED illumination is achieved when a semiconductor crystal is activated so that it directly produces visible light in a desired wavelength range. With the continuous development of lighting technologies, more possible future applications of LEDs will be [...]
ADVANTAGES
DISADVANTAGES
Good energy output for monochromatic light emission in relation to the incandescent light sources that need filters
High purchase price especially for white and blue
Less heating,even with high performance diodes
Low light efficiency in relation to the fluorescent sources
Long lifespan,less maintenance
Not yet adapted to general illumination:low flux/LED,behavior of luminous characteristics with time
High resistance to impacts and vibrations
Strong [...]
There are quite a few advantages to using LEDs. Generally they are heatless, use 90% less energy, and last ten years. They are also smaller and do not contain any dangerous chemicals like mercury. They can readily be put in places that have always been too small or out-of-the-way for many incandescent lights, as well [...]
