Neon signs have decorated shops, highways, street corners and window sills for many years. LEDs are a relatively new invention, but they have already started over shadowing the neon signs. There have to be certain advantages in the use of LED, for it to be able to eat into the market share of the ever popular neon signs.
A LED or Light Emitting Diodes is a solid state semi-conductor device which can convert electrical energy directly in to light energy. To get a glowing sign from LED, they are placed adjacent to each other in a polymer jacket, just so far apart as to permit glow overlap and give a constant regular light. This makes LED signs very flexible and easy to handle.
Neon signs on the other hand are made from real glass in the form of tubing and are filled with neon gas. They are fragile in handling and transportation and have high maintenance costs. Besides the difference in the method of construction and handling, there are a large number of differences which go to make LED the chosen alternative to neon signs.
Some of the major differences are as follows:
• LED being at least a third to a quarter the thickness of neon tubing occupies a lot less space height wise as well as in depth.
• LED does not heat up the way a neon sign does so it can be hinged to the base where as neon sign has to be extended at least an inch or so away from the base thus requiring more depth in spacing.
• It is easier to transport and ship LED signs as compared to neon signs as they can withstand a lot rougher handling being less fragile and also being less bulky they occupy less space.
• LED signs are bright and clear to read from any distance while neon signs tend to get blurred if viewed from a distance. Even during the day time with the sun shining bright, LED signs can be seen to glow clearly, while you can't make out if a neon sign is on or off.
• LED signs have a lifetime of 100,000 hours where as neon sign are plagued by constant gas leakage and need to be refilled.
• LED signs are more eco-friendly as compared to neon signs, as they do not emit any gases while neon signs leak out toxic gases such as argon and mercury.
• LED signs use just 10 watts of power as against 8-10 times higher wattage used by neon signs thus they have much lower running costs.
• LED signs are extremely malleable and can be twisted in any direction with ease, neon signs, being made of glass need specialized processes to turn and twist.
• LED signs being made of a number of LEDs put together can use animation, flashing and flickering with ease, while neon signs do not offer such options.
It seems as though the new technology of LED signs will be around for quite some time.
Difference Between Led And Lcd
Flashlights are highly essential for many types of occupations, and are also very handy to have around the house. Here is a little bit of trivia for those who want to know more about these handheld torches: It was in 1898 when the concept of a tube mounted and battery powered bulb was first introduced. Later on, the Eveready Battery Company produced more improved models of the original concept.
Today, flashlights have evolved into different kinds depending on usage, as well as a multitude of sizes for various needs. Medical flashlights can be mounted on pen tips and powered with pill-sized lithium batteries, while some workers' flashlights are mounted on hard hats and helmets. An American inventor was able to come up with a concept of a flashlight that does not run on batteries, and you need to charge up the power source by shaking the tube or cranking the handle attached to it. These torches were able to work via electromagnetic induction.
The most important feature of a flashlight that determines its usability is of course, the light bulb. There are two most common types of flashlight bulbs in the market today, and they are what are usually bought for home and personal use. These are the LED bulbs and xenon flashlight bulbs. Here are some notes to help you gauge the difference between the two.
Xenon flashlight bulbs follow the same principle as incandescent bulbs, wherein a small tungsten wire in the bulb is heated to produce light. Within the glass chamber of the bulb is a gas, which used to be argon, but is now commonly xenon. The gas helps stabilize the heating of the tungsten wire, such that it does not produce a flame. Maglite is a very popular company that manufactures torches with xenon flashlight bulbs.
Another type of flashlight bulb is the LED, which stands for light-emitting diode. With the use of semiconductors and a source of electricity, light can be produced. These flashlight bulbs are said to be more energy efficient, and are more resistant to shattering when the torch is suddenly dropped. More flashlight companies today make use of the LED flashlight bulbs, because they require less energy from the battery to produce a sufficient brightness of light. However, LED flashlight bulbs can still produce heat, contrary to the misconception that they do not. LED flashlights will probably save you money in batteries over time.
