PPT-Inside an Incandescent Light Bulb

You are will be using an incandescent light bulb to build circuits in class Incandescent Light Bulb An incandescent light bulb is an electric light bulb that passes electric current through a . An incandescent light bulb is a simple device with a tungsten filament It consistently produces the same type of light with the same characteri stics However LED lights are far more complicated Their color comes from a phosph orus coating which if a dealing with light and vision..

By: Buckswood International School - Tbilisi. Energy and Civilization. Energy consumption of the last 30 years far exceeds the amounts harnessed throughout the preceding centuries. CFLs vs. Incandescent . Light Bulbs. CFLs last 10 times longer. Use roughly ¼ the energy. Produce 25% less heat while producing more light per watt. Save YOU $$$. Purchasing CFLs. Check the label.

Non-luminous:. an object that do not produce its own light and is visible due to reflected light (. eg. . a tree). Sources of light. Humphry Davy created the first incandescent light by passing current through a platinum strip. It caused a glow and did not last long, but marked the beginning of incandescent light development. Experimenters continued over the next 70 years to use platinum and iridium. Frederick used a platinum filament in an evacuated glass tube to make a light bulb. .
