Over the past 25 years I have had the unique opportunity to talk directly with many of the professionals and instructors who use Overhead Projectors as an integral part of their profession. The stories they have shared with me have given me direct insight to some of the most common problems experienced by owners of today's and yesterday's Overhead Projectors.
This is the second article in a series of articles that will be written from a professional Electronics Technician's point of view in regards to some of today's most common Overhead Projector problems.
A question that I am asked quite frequently is; ?Why do I seem to be endlessly replacing the lamp socket in my Overhead Projector??
This is by far one of the most common problems among all of the users of Overhead Projectors today. The cause of this problem is very simple in fact and could be avoided very easily. What happens in most cases is that the projection lamp is not being fully seated into the lamp socket. Because this is an electrical connection, the pins on the projection lamp must be completely seated into the lamp socket. If the projection lamp is only partially seated into the socket the arching between the lamp socket contacts and the projection lamp pins will take place.
The cause of this arching causes the contacts of the lamp socket to burn and score. Over a very short period of Spotlight Housing Manufacturers time this arching causes irreparable damage to the lamp socket in which the only choice is to replace it. In some severe cases I have seen the contacts in the lamp socket and the pins of the projection lamp electrically welded together due to this arching.
The best way to prevent this from happening in your Overhead Projector is to make sure that the Projection Lamp is fully seated into the lamp socket when replacing the projection lamp. It may feel like you are pressing on the projection lamp to hard, but unless you feel a slight click when seating the projection lamp into the lamp socket, you most likely have not seated the projection lamp properly.
If you have a basic knowledge of Electronics or basic wiring the lamp socket is something that most end users can replace themselves, otherwise this problem should be handled by a professional service technician.
The correct home accents can make a massive difference to your home décor. Consider the scenario: you have your home as you want it - you think, but there appears to be something lacking. That bit of' oomph' - that pizzazz that makes your rooms stand up and scream to be admired. How do you achieve that? How do you make your home the talking point of the neighborhood - in the best possible way of course?
For starters, do you have candles? If not, get them, and even if you have them, what are they held in? Some plain, uninspiring candlesticks or are they displayed in beautiful white angels with lovely feathered wings and draped gowns? Or how about solid brass replicas of the candle holders in Chartres Cathedral, substantial examples of medieval gothic art that will showcase even the best of rooms?
No? Where is your imaginative flair? How about some wall candles, in beautiful Byzantine pendant lanterns, with vibrant purple glass held in hand-tooled metal scrolls, dropping 18 inches down from a chain and embossed bracket. If that is too ornate, you can choose from any number of Egyptian themes, offering your room a dramatic mythological look.
These are just a few ideas of how candles can transform an ordinary to good room into something spectacular, but you can do even more. What do you have on your coffee table? The usual suspects: magazines, a couple of ornaments? How about a fantastic chess set with goblins, gremlins and trolls sitting on a sliver and ebony effect top, encased in a solid wood base to offer an absolutely stunning chess board and set.
There are many other chess set and board designs you can choose for, or you might prefer a beautifully expensive-looking Egyptian box, embellished with chariots, hieroglyphs and scarabs in an overall gold effect finish, and costing you under $40, or an art nouveaux peacock-shaped box containing potpourri that both decorates and offers your room a delicate perfume.
These home accents and more can make a significant difference to the look and feel of your home décor, but if you want your rooms to really stand out, then be brave and bold. First think of the time and then of the light. First the time: clocks! These can very significantly change the look and feel of opulence of any room, whether it is a hall, a lounge or even a kitchen. Forget the kitchen for now and focus on your lounge: that's where most of your time and that of your guests will be spent.
With clocks you can think big or think small - you should think both. First the small: a Saint Remy Cherub clock, over a foot wide, seven inches deep and 19 inches high. Yes, that's the small if you want your house to be admired. This is decorated in a typical golden rococo style, with cherubs with pan pipes on either side. The quartz movement with Roman numerals is accurate and is replicated in resin to look just like the brass original. This is a beautiful clock for a mantelpiece, chimney breast or large sideboard or table.
Now the large: if you like Egyptian, an over 3 foot high, 20 inches wide statue clock named the Temple of Amun Royal Egyptian Clock, after the temple at Karnak. This is breathtaking and includes the famous eye of Horus hieroglyph on the clock that rests over the head of the falcon-headed god Horus standing between two pillars. This will transform any room or entertainment area.
If that is too garish for you, then a 26 inch regulator wall clock will also look fabulous on the wall of any room. It is of an open design displaying a 7-day movement operated by a pendulum and hanging weight. A bell on top strikes the hour and the weight drops as the pendulum regulates the time. If you prefer your clocks to be traditional and not quartz, then this is for you.
Finally the lighting: your lighting should be more than just a light bulb in the middle of the ceiling. If it must be that, then at least make it a chandelier. However, far more inspiring is to have some floor lamps and lamps on your tables and other horizontal surfaces. For the latter an Aberdeen lamp would offer the gothic look, crafted from metal and resin filigree, with frosted glass panels round the lamp. You really need to see it to admire it, but if you prefer some more classical, then a 20 inch high LED Heat Sinks Suppliers art deco Peacock Maidens lamp might suit you, with two maidens with feathered headdresses holding up the lamp between them. This is a beautiful lamp.
For the floor, a Place de l'Etoile lamp would go very well with the maidens lamp above. This is just over 6 feet high, in the form of a white female figure on a plinth holding up the light at the top of her raised arms. The bulb is inside a cream lamp shade pointing upwards, and this is a true work of art in mid-18th century style.
Any of the above home accents will make a difference to your home décor, but to combine a number of them into one room would definitely make your guests gasp and you would be a very popular hostess. :: برچسب ها : LED Heat Sinks Suppliers ,
