Transcript of Lightbulb Product Life Cycle

Process/Manufacture The tungsten in the filament is mixed with a binder and coiled around a steel mandrel
The mandrel is dissolved with acid and the filament stays in a coil shape
Lead-in wires are made out of nickel-iron and dipped in a borax solution to stick to the glass
The bulb contains a mix of argon and nitrogen and is blown into its shape
The base is made out of glass coated with aluminum Materials Tungsten mixed with a binder
Nickel-Iron wire dipped in a borax solution
Aluminum Lightbulbs Use Used in
street lights
... Dispose Some types of light bulbs can not be recycled
The Home Depot will take certain types of your used lights for free (CFL's)

http://www6.homedepot.com/ecooptions/stage/pdf/cfl_recycle.pdf What is meant by "product lifecycle?" Why is it important for companies who make products to research and determine a product's potential lifecycle? What would you change about your product and why? Do you think your product will evolve or become obsolete over time? Why? What is a trade-off? Do you think that trade-offs were made during the design phase of your product? Why is it important to recycle? How do product designers play a role in recycling? What role does society play in the recycling effort? What can you do to help? Raise and Extract A product lifecycle is what happens to make a product from start to finish. (From the extracting of materials to how it is disposed of or recycled) When where the product will end up is considered, companies have the ability to choose what they can change about the product to better help the environment. Glass - Starting with a lot of quartz sand, sodium carbonate, lead oxide, sulfur, and sodium oxide are added and mixed. Next the mix is heated, the bubbles are removed by stirring and the glass is shaped and left to cool. Steel - This process starts with iron ore, the rock containing this is ground up and extracted using magnetic rollers. A mix of ore and coal is heated in the furnace to make iron, from this steel is made. I would change how some of the main pieces are made because there are many materials that are used that aren't in the final product. Also, since about 95% of the energy that goes into a lightbulb is converted into heat instead of light I would change the efficiency of the lightbulbs. The product will evolve because people need light to see in the dark and no matter what there will be some form of a light bulb used. A trade-off is when you give something up in return for something else. I do think trade-offs were made during the design phase of making the light bulb. They probably had to decide to pay a little more in order to make energy-efficient light bulbs because they knew in the long run they would make more money on them. If people didn't recycle the environment would be so degraded and all our resources would be either gone or not enough would be able to grow. Recycling helps us be able to take less from the environment because we are reusing what we already have taken from it. When a product is designed, the designers need to take into consideration what materials go into the product and therefore they are determining if it needs to be thrown away when it is time for it to be disposed of or if it can be recycled. Society plays a role in the recycling effort because it is up to us to choose to recycle the products we are disposing of. To help each person can choose to keep recycling bins for bottles, cardboard and paper, and recyclable plastics. This is important because each person adds to the big picture.
