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).
Architectural lighting design focuses on three fundamental aspects of the illumination of buildings or spaces. The first is the aesthetic appeal of a building, an aspect particularly important in the illumination of retail environments. Secondly, the ergonomic aspect: the measure of how much of a function the lighting plays. Thirdly is the energy efficiency issue to ensure that light is not wasted by over-illumination, either by illuminating vacant spaces unnecessarily or by providing more light than needed for the aesthetics or the task.
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.
