Bulb Lamp Source
lamp questions?
i want to know how hot it would be right next to (about an inch away) a 60 watt bulb. i want to build a lamp and i need to test out some materials to see if they can withstand the heat. on a similar note, do you need special/thicker wires and switches to make something that would plug into a wall/do you need to add something to a lamp so that the bulb doesn't explode?
please include a source.
thanks
A lot depends on the design of your lamp.
Always try to provide some way for air to flow around the bulb. Remember hot air goes up, so give that air some way to escape and be replaced by cooler air. Look at a typical table lamp with a lamp shade. The shade is open at the top and bottom to allow air to flow up past the bulb and cool it.
You don't need a large opening, something 6 inches across is more than enough.
If you don't have openings to allow the air to flow, temperatures will be a lot higher. The 60 watts of heat has to get out somehow. If you don't allow for air flow, it will escape some other way, by heating the other parts of the lamp up.
If you have the openings as described, most materials would be ok, as long as they are not flammable. Build a fixture and put the test materials near the lamp and see what happens. I'd test at 1/2 inch so you know it will be OK at 1 inch. See if it turns brown or discolors in any way.
You can buy lamp kits at hardware stores. They contain the power plug, the cables, a switch, and a lamp socket. Start out with one of these.
PS, should have mentioned this before. This all assumes a 60w incandescent bulb. If you use a CFL *compact flourescent light", one that puts out the equivalent of 60 watts of light will dissipate only about 20 watts and will run much cooler, giving you a larger choice of designs and materials.

How to Replace the Lamp (Bulb) on a Sony Wega TV
Led Light Bulbs
Led light bulbs will one day become the dominant source of lighting on the planet-if not the exclusive source. They solve a multitude of economic and environmental problems that have plagued and continue to plague users of other types of lamps. The reason for this lies in the manner in which a led bulb generates light. Unlike incandescents and fluorescent bulbs, a led light does not utilize a filament or any type of luminary gas. Instead, led lighting bulb technology is based on something completely different-a semi conductive component known as a "diode." By passing a low voltage current through a diode, one can agitate electrons within its composite substances, causing light to radiate into the surroundings. This light is cool burning and will not cause heat pollution in work and living areas. Because these bulbs do not rely on inert gases of any kind, they pose no threat to the environment, and the substances of which they are composed are virtually unbreakable compared to standard lamps.
Led light bulbs offer every color in the rainbow now to both home and commercial users. A led's color directly results from the chemical composition of the diode itself. The most recent breakthrough came a few short years ago, when Chinese scientists learned to mix blue and yellow in the precise combination necessary to create a white LED. Previous to this advancement, led light bulbs always represented a primary color, and as such were very useful for display, indicator, and instrument lighting, but not yet ready to replace incandescents whose bright white light established them long ago as the world's primary source of artificial lighting. When white led bulbs entered the lighting market, an explosion in size, design, modification, and engineering followed as lighting manufacturers immediately saw the benefits of creating alternatives to previous technologies and seizing the opportunity of the moment to pass on both green technology and cost-conscious savings to corporate and individual clients. Not long after these developments occurred, California passed a law that now requires all incandescent lights be replaced no later than 2010, making retrofitting a legal matter at this point for West Coast residents as well as a cost and earth conscious decision.
Linear strip lights utilize a bulb type known as "festoon," and many high-end resorts, casinos, and country clubs in California use festoon bulbs for both seasonal and year round decorations. With a ban on incandescents now pending, corporations and individuals alike in California will now have to look for retrofitted alternatives if they are currently using any type of incandescent festoon light source. This is not as big a problem as it may sound, nor is it expensive when one considers ROI beyond up front procurement costs.
In an era where concern over global warming is approaching the level of worldwide alarm, now more than ever is a time to consider going "green," not necessarily in terms of the color of a led light bulb, but in terms of its innate quality and value. It never hurts a company's public image to promote itself as a leader in newer, more efficient forms of non-destructive power. Furthermore, led lights feature a bulb life that ranges from 30,000 bulb hours to over 100,000 bulb hours. Replacements are very rare, and therefore, seldom a cost factor to consider when forecasting budget. Immediate return on the front-end investment one makes in begins to accrue monthly on every subsequent power bill post retrofitting date. This is truly a win-win scenario for anyone.
