As happens with any technology, many new and fun uses have emerged for LED light bulbs that were probably never considered when they were first invented.  Model train enthusiasts have begun using LED light bulbs as the headlamps in the trains, for street lamps, and for general accent lighting to highlight areas of their track.  With LED lights being so small (about the size of a pencil eraser) and long lasting, they actually seem tailor made for this kind of work!

LED lights are also commonly used in home theatre systems, and not just in the jumbo television screens.  Many plasma televisions that are hung from the wall are better viewed with some soft backlighting.  This can prevent eyestrain and also provide a more professional appearance.  LED lighting is perfect for this, since they are small and easy to place in compact areas, don’t give off heat that might damage the television, and are much quieter than compact fluorescents thereby eliminating any competition for the sound from your TV.  LED lights can also provide thousands of color combinations, and can be dimmed to provide softer light at different times of day.

Visual arts are also benefiting from LED technology.  Many artists are experimenting with LED lighting on their paintings, sculptures, and installation pieces.  With so many different color combinations and the fact that lighting can be very narrowly directed, LED light bulbs are a wonderful addition to experimental art pieces.  Of course, all of these different uses have one particular thing in common.  They all require lighting that is energy efficient, long-lasting, and maintenance free.  When lighting becomes a hobby, it’s usually important to keep the costs low and limit the number of replacements.  Because LED light bulbs fit the bill, they are an easy replacement option for the current lighting technology.

Did you know that almost all huge video screens, commonly seen in concerts, sporting events and popular outdoor areas such as Times Square in New York, operate using LED technology?  They need to because the screen has to be bright enough to be seen from a distance and, if outdoors, it competes with the brightness of the sun.  Normal television technology can’t be used in these circumstances.

Jumbo TV screens are made up of pixel modules that usually range in size from 4mm to 4 cm (0.2 inches to 1.5 inches).  Each pixel module contains LEDs that combine the colors red, blue and green to form all other colors needed to produce the desired images.  Thousands of these modules are then arranged in a rectangular grid to form a jumbo TV screen.

Huge display screens like these are run by computer systems and use a significant amount of power, although less than they would if they used other lighting technology.  The computer system acts as a translator by receiving the incoming TV signal, calculating the color signals and intensity required, and converting this information into instructions for the display.  The power system obviously acts as the power source but also manipulates the intensity so that each LED module delivers the correct brightness.  A typical 20-meter jumbo screen may consume up to 300,000 watts of power.

The use of these massive TV screens has increased greatly in recent years, as the cost of LED technology has dropped.  Sporting events that used to simply show game scores now broadcast fast-action highlights.  Bustling street corners like those found in New York and Tokyo have transitioned from static billboards to full-motion advertisements.  Even shopping centers and office buildings use jumbo screens indoors to educate or inform visitors.  Thanks to the amazing benefits of LED and LED Light Bulbs, we now live in a world where a TV screen can be found almost anywhere!
