Lighting fixtures come in a wide variety of styles for various functions. The most important functions are as a holder for the light source, to provide directed light and to avoid visual glare. Some are very plain and functional, while some are pieces of art in themselves. Nearly any material can be used, so long as it can tolerate the excess heat and is in keeping with safety codes.
Extensive luminaire photometric designing calls for consideration of the amount of functional light present, the energy expended, as well as the aesthetic impact supplied by the lighting system. Some buildings, like surgical centers and sports facilities, are primarily concerned with providing the appropriate amount of light for the associated task. Some buildings, like warehouses and office buildings, are primarily concerned with saving money through the energy efficiency of the lighting system.
Typically, they project down from the ceiling and are usually the biggest lighting piece found in the kitchen. These fixtures can also be hung over a breakfast nook or a kitchen table. There are two types of ceiling fixture; flush-mount ceiling fixture with the glass or diffuser touching the ceiling and semi-flush ceiling fixtures where the bowl projecting from the ceiling such that it hangs a couple of inches away, with indirect light reflecting from the ceiling (think of it like an upside down umbrella).
