FREQUENTLY ASKED QUESTIONS
The most basic term, LED, is an acronym for Light Emitting Diode. All of this simply means that the diode will be a computer chip on a circuit board. Some people think of the properties of the diode. The diode causes it to produce light when an electric current has passed through it. Prior to the 90’s, the LED was on a small-scale application. The LED has followed the same levels of efficiency that the computer has and it causes a great deal of curiosity. The uses of LED’s has become just as wide and refined as the computer.The Light Emitting Diode is a very solid piece of technology and has some interesting points to its production. There is no glass bulb to overheat in the LED. With the way that LED’s are produced there is no pressured gases, mercury, or burning filament. The LED breaks the traditional energy loss of bulbs which is around 90%. One of the uses of the LED is found in the VCR, DVD, or the remote. These are just a few of the uses that have elevated the LED to prominence.
Yes. The E26 is known as the standard 120 Volt base in the United States. The European variant which is E27 is rated at 220 Volts. The other difference is that the E26 is 26 mm and the E27 is 27 mm diameter. However, the bases are interchangeable with no problem. Also, the sockets and the bulbs are theoretically interchangeable even though there is a difference in the voltage rating. Only the E26 bulbs labeled as universal line-voltage can be used in both the E26 and the E27 sockets.
Technology makes things more efficient but it also can seem more expensive in the exchange period. The energy savings and replacement cost of inefficient bulbs are not always seen, but early on the LED light appears to come with a fair amount of sticker shock. Newer technology is constantly evolving and becoming more advanced which means that it has to be structured in a way that brings down costs. As the use of the technology begins to become more widely spread, the cost of the technology will definitely decrease. The LED was once mounted on a sapphire substrate but now there are experimentations with various silicon substances to replace it. The incandescent light bulb will probably stay at a lower price point than the LED light due to what goes into making the components. The Light Emitting Diode are not based a heated filament in a glass; they are each a lamp that is the product of soldering together a number of parts. The parts which are the heat sink, the driver, the circuit board and the LED chips are engineered for specific lighting applications. That makes them really different and very efficient to use. The LED light is not a disposable object but more lasting like an appliance. Nation Light LED will continue to build products that are of very high-quality and will be only name brands. The LED chips reflect a lot more years of research. The LED bulb promises about 5 years of useful life, so this is why chip manufacturer have been in business for as long.
There are many different things that allow the LED to have an advantage over traditional lighting. The performance of the LED will definitely match but in most cases it will surpass the performance of all other lighting choices. One of the big things is that the LED will operate on less energy than the incandescent lights. Another big performance issue is that it lasts longer, an average 10 years. The LED is also more durable as a solid state, shock-proof, technology; the LED can be housed safely in plastic instead of glass. The LED is twice the efficiency of a CFL which does not stack up against it in terms of reliability. The fluorescent light can rely too much on its chemical reactions with gases which is why it is less useful than the LED. The chemical reactions of the florescent light can have adverse effects because of the upside-down installations. The final problem is that the ballast of a CFL is not intended to handle rapid on-off cycles – all of which explain why so many people are dissatisfied by these bulbs.
The International Electro Technical Commission has a two-digit number that it has established to provide an Ingress Protection. This is the rating to any piece of electronic equipment and is found on the enclosure of the electronic equipment. In the digits, the first one indicates protection against ingress of solid objects and the second indicates protection against ingress of liquids.
The previous way to compare lighting was much different from today. In the past, the brightness of a bulb which was known as wattage was used. The power of the bulb was used to determine level of energy it consumed. If the disparity between incandescent and LED technologies were observed there would be a little clarity on the level of power. Now when the power or brightness is of concern it is done by observing the lumens. The observation of LED and incandescent, shows that the incandescent projects light in 360 degrees from the ceiling while the LED lights are directional and can focus all the whole of the light they produce exactly where you want it, and nowhere that you don’t. Looking at the differences will also move toward the color temperature which has, in the past, been very difficult to control. The lack of control was because you had to take whatever color that particular bulb would produce. The warmth of the bulb typically meant that a white bulb which was about 3000K would be less than a cool white bulb which is about 5000K. In simple terms the LED is intelligent and a very solid-state technology. Now the LED is seemed to be able to produce up to 16 million different colors, each a different temperature.
The very basic idea of the lumen is that it is a unit that measures luminous flux. The flux is also the total amount of light that is visible and emitted by a particular light source. The example is that the light source emits one candela which is about one candle’s worth of light. The luminous intensity is the next level of explanation, one steradian is a solid angle or a picture of light waves emitting from a particular source, in the shape of a cone. The total luminous flux emitted into that steradian is then known as one lumen.
The next measure that is needed for the LED is the Lux. The Lux is just a lumen per square meter, so the main variance between the two, lux and lumen, is only that the lux takes into account the area where the lumen is spread. An example is that 1000 lumens could be concentrated into an area of one square meter. An identical 1000 lumens which could be spread out over ten square meters could theoretically produce a dimmer illuminance of only 100 lux.
