This is a term that’s now used widely and regularly, but how much do you actually know about LED lighting? LED stands for light-emitting diode which is then part of a bulb or lamp with a greater lifespan than that of the old incandescent lamps. LEDs providing white light also outlast most fluorescent lamps, whose longevity is also affected considerably simply by your switching them on or off, by a much higher multiple.
Using LED products
These are compact and especially good at providing a narrower beam of directed light, rather than simply throwing it out in all directions, they also usually include elements within them to assist with heat dissipation. In your home, you might find them terrific for reading or to help you focus specifically on detailed hobby activities such as needlecraft, jigsaws, model-making, and the like. For those times you are happy with a wider spread of light, LEDs with diffusers are usually a good answer. An alternative is a series of directed spotlights, often adding character to different areas of your room. This is one reason why you are increasingly likely to discover such products being used as light sources in museums, art galleries, and other public venues.
In the situation where fixtures are designed for fluorescent tube lighting, you might not be a fan of that specific style. The good news is that LED tube lights, often using several LEDs within the one tube, have been produced which can be used as replacements in many products, although it is wise to check with an expert before making changes to any of your current appliances.
A brief history to finish
The history of LED development is, unlike the product, slightly hazy in places. It has been reported that an assistant to Marconi published an article over a century ago covering some experimental findings. A couple of decades later, Russian scientist Oleg Losev, carried out more substantial research. No practical work appears to have been done following this, but, after the Second World War, the pace quickened. The first commercial LEDs were produced in the early 1960s. Nowadays, you’ll find them in everything from traffic signals to games consoles.
The next time you are looking for a cool and directional lighting source, not only will you appreciate why choosing LED products makes good sense, but do feel free to throw a casual fact or two into the conversation. SHOP LED Light NOW
http://youtu.be/Ym0P7Exk8MA LED into a light bulb requires the integration of some pretty sophisticated technologies.
- Components on the circuit board is often assembled by hand because its still too complicated for factory machines
- The actual LED wafer can cost as much as £5 a unit
- The brightest LEDs generate blue light. So in order to get the more natural white glow, manufacturers typically coat the bulb with yellow phosphor, an expensive rare earth metal compound imported from China
- LEDs additionally require the use of drivers to convert energy into electrical current. This component alone can cost up to £3
- Although LEDs burn cooler than Edison bulbs, they still need a conducting material to dissipate the heat. The aluminum used to accomplish this can cost as much as £2
Some newer technologies that bulb-makers are hope will help bring down the cost in due time, some of which include:
- Using larger wafers that would allow LEDs to be built.
- The production of green LEDs that when mixed with red and blue ones create white light.
- Smaller heat sinks that require less aluminum.
LED Lamps will significantly reduce your carbon footprint because they use far less electricity which creates large amounts of CO2 in its production. LED Lamps do not have any hazardous substances like the mercury in CFLs and accordingly can be easily disposed of at the end of their life but as they last over 30 times longer than a traditional light Lamp they only create a fraction of the landfill.
