High Brightness LED Projector Lamps Market Debut - Environmentally Friendly and Mercury Free

!±8± High Brightness LED Projector Lamps Market Debut - Environmentally Friendly and Mercury Free

By necessity projector manufacturers have used high pressure mercury containing projection lamps to achieve adequate projector brightness (ANSI lumens). Over recent years, manufacturers have been able to greatly reduce the amount of mercury used but, not eliminate it. Unfortunately, high pressure (200 atmospheres or more) mercury lamps remain a danger to consumers if mishandled upon replacement and to the environment if not disposed of correctly.

Recycling facilities can recover the mercury and achieve a recycling rate of up to 97 percent. Realizing the problem, some projector manufacturers, such as Epson, have set up their own recycling programs. However, despite legislative measures in many countries, most mercury containing bulbs end up in landfill. Disposal in this fashion can result in the release of mercury into the environment and contamination of the food chain. Considering that the EPA have mercury as the most hazardous metal on the list of industrial pollutants (potent neurotoxin to humans), this is not a good outcome.

Fortunately, a solution is on hand in the form of Luminus Devices, PhlatLight technology, a new solid state light source combining both LED and laser technologies. This new lighting technology is 100 percent free of hazardous materials including mercury and lead (RoHS compliant). There are further environmental (and financial) benefits to using this new projection lighting technology including lower power consumption and vastly longer lamp life of up to 60,000 hours (which is realistically the lifetime of a projector) compared to about 2,000 to 3,000 for current high pressure mercury lamps.

Because of limited achievable brightness levels, the first PhlatLight LED-based projectors have been ultra-portable pocket projectors such as the recently released Optoma EP-PK-101 Pico Pocket Projector. PhlatLight LED chipsets such as the January 2009 released PT-121 and the PT-120 are now capable of brightness levels of up to 3000 ANSI lumens which is suitable for home theatre projectors and most business projector applications. The PT-120 and all other PhlatLight chipsets can be used with the DLP, LCoS and LCD micro-displays commonly used in projectors.

In January, Luminus Devices announced the consumer market release of the first full HD (1080p) DLP projector, the Delta Electronics HT-8000, based on its PhlatLight PT-120 LED chipset. If you are looking for a new projector, keep a lookout for this new technology as it can be expected that many new models will be released throughout 2009.

How Does an LED TV Work?

!±8± How Does an LED TV Work?

Simply put, an LED television and an LCD television are one and the same thing. The difference between a standard LCD television and an LED model lies in the method of backlighting. Normal LCD screens are built by sealing a layer of liquid crystal in between two glass panels. Behind this are a series of Cold Cathode Fluorescent Lamps - CCFL - that project light through the crystal polymer. When a controlled current is run through the crystals, they either add colour to the light, or block it out completely. In LED televisions, the CCFL lighting is replaced by a sequence of LEDs. As they are much smaller than CCFL lights, televisions that are LED-backlit can be made much thinner and lighter than regular LCD models. Some are even under an inch thick! LED televisions are also capable of greatly increased dynamic contrast - the ratio of difference between black and white - use less power, and are more environmentally friendly when disposed of.

However, the differences don't end here. Currently there are two commonly used methods of LED backlighting, known as Edge LEDs and RGB Dynamic. Each has advantages and drawbacks, so if you're thinking of buying an LCD television, it's good to know what each method has to offer. In RGB Dynamic models, a sequence of red, green and blue LED lights are positioned behind the screen. When an image is displayed featuring dark colours, the LEDs in that area are dimmed while the intensity of the colour is increased. As a result, televisions with RGB Dynamic backlighting have higher Dynamic Contrast ratios than any other LCD model, although they are still second to plasma technology when it comes to 'true' blacks. The downside of this method is a loss of fine detail on small, bright objects that appear against a dark background - an image of a night sky is a good example.

By contrast, the Edge LED method is a completely different kettle of fish. This type of backlighting involves the placement of white LED lights around the outside edge of the screen. A light-diffusing panel is then placed behind the screen, which compensates for the lack of light coming from the centre. Edge LED backlighting is not capable of the same Dynamic Contrast ratios offered by the RGB Dynamic method, because it can't dim the backlight as precisely in a localised area. However, it is the cheaper of the two methods, and televisions carrying this technology are some of the thinnest and lightest on the market, making them extremely easy to wall mount.

So there you have it - there are pros and cons to LED backlighting, just as there are pros and cons to LCD and plasma flat screen TVs [http://www.panasonic.co.uk/html/en_GB/Products/Viera+Flat+Screen+TV/Plasma+TV/Plasma+TV+Overview/2525930/index.html]. Both LED methods are currently quite expensive, so don't expect to find them in any budget range televisions for the time being. However, with technological breakthroughs occurring all the time, it probably won't be long before LED backlighting becomes yet another industry standard.

How to Choose the Best Replacement Toshiba Projector Lamps

!±8± How to Choose the Best Replacement Toshiba Projector Lamps

The lamp is the integral part of any projector, so this is one area you can't afford to skimp on - although it doesn't have to be as expensive as you might think. Original Toshiba projector lamps are precision made to exacting standards - currently, there are only four or five manufacturers worldwide making high quality projector bulbs - so it makes sense to purchase one recommended by the manufacturer, rather than a cheap and inferior copy.

If this makes you balk, you can make substantial savings by buying your Toshiba projector lamps online, from a supplier endorsed by Toshiba. To bring costs down further, these same suppliers often sell duplicate lamps as well as manufacturer's originals. These are not always inferior products; they can be as good as the real thing, but use different materials (such as the housing, packaging etc). The important part - the bulb - will either be a Toshiba original, or a top quality alternative from a manufacturer such as Osram or Phillips.

The things to look out for are suspiciously cheap "Toshiba projector lamps" packaged to look like the original and delivered from a foreign supplier. On closer inspection, these lamps are often fake and have not passed the rigorous quality controls imposed upon genuine alternatives. They are illegal, and often dangerous; nobody wants to have a mercury vapour bulb explode in their face. Yet this is what can happen if you buy projector bulbs from a disreputable source.

Of course, you can't "see before you buy" online, which is why it's so important to only use sites endorsed to sell the original product. If they also sell replica projector lamps, these should be clearly packaged to reflect this fact and you should always get a full guarantee and "no quibble" returns policy, whichever brand you choose.

When you see how projector lamps are made, it's easy to see why they're so dear. This is not a high yield, bulk-consumable product. Mercury vapour bulbs are designed to last a long time, and replacements have a finite lifespan (owing to the possibility of loss of pressure over time, leading to a duller output). Consumer demand is therefore quite low, meaning Toshiba projector lamps are made in relatively small batches. The machinery is very expensive, and since it is used throughout the entire Toshiba range it must be carefully reset and recalibrated for each batch. The process uses exotic raw materials, such as quartz glass and mercury. It is also extremely labour intensive, with a team of specialist scientists and engineers overseeing quality control, calibration and more.

Toshiba projector lamps are sold as a sealed unit, complete with the housing and lens. Replacement of the ARC bulb alone is a highly specialised process and outside the realm of DIY. In fact, the housings are made so they can't be dismantled. There are numerous reasons for this - the main one being safety. The arc tube is sealed with mercury vapour at ultra-high pressure. Mercury is essentially hazardous, as is exploding glass. Buying bulbs in sealed units ensures safety of both user and machine. It also ensures that Toshiba projector lamps run 100% efficiently, with efficient wiring and a scratch-free reflector.

Whether you choose to buy the Toshiba original or a reputable copy is up to you.
