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).
The more transparent the lighting fixture is, the higher efficacy. Shading the light will normally decrease efficiency but increase the directionality and the visual comfort probability.
The PH-lamps are a series of light fixtures designed by Danish designer and writer Poul Henningsen from 1926 onwards. The lamp is designed with multiple concentric shades to eliminate visual glare, only emitting reflected light, obscuring the light source.
Other buildings, like casinos and theatres, are primarily concerned with enhancing the appearance and emotional impact of architecture through lighting systems. Therefore, it is important that the sciences of light production and luminaire photometrics are balanced with the artistic application of light as a medium in our built environment. These electrical lighting systems should also consider the impacts of, and ideally be integrated with, daylighting systems. Factors involved in lighting design are essentially the same as those discussed above in energy conservation analysis.
