In everyday life, we need to do many different activities. This requires the use of all light from the Sun is important, but the time and place of making the utilization of electricity as the energy source, again profited by our lamps usually are selected to be used in the General's desk for reading a book or work, which is.Designed to have many different shapes, resulting in very light enough reading and mathematical skills, including applied in our daily lives. Group to study the basic information about three dimensional geometry. Appropriate lighting research activities and apply knowledge leads to artificial lighting 5 shapes include rectangular base pyramid, cylinder, cube, cone, and Prism, trapezoid, by control and height of cut geometric areas used to make these lanterns. Lamp made from a release of artificial lighting, when can then bring to experiment with the same light bulb. Power 40 W, and then use the tools of measurement of brightness (Lux meter) measurements of the light from the lamp to the different types of light at a distance of 100 centimetres, given that studies have found that the rectangular base pyramid lamps, light intensity values than other types of lamps and lanterns, Prism, trapezoid, the minimum light intensity values. Which result from this analysis it can be seen that the shape of the different lighting, different lighting using lamps, we should use such knowledge, decided to purchase the lamps that light the most efficient for us to use.
