In optics, a diffuser (also called a light diffuser or optical diffuser) is any material that diffuses or scatters light in some manner to transmit soft light.Diffused light can be easily obtained by reflecting light from a white surface, while more compact diffusers may use translucent material, including ground glass, teflon, opal glass, and greyed glass.
A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers to display information. Liquid crystals do not emit light directly [1] but instead use a backlight or reflector to produce images in color or monochrome. [2]
In some commercially available models the diffuser is removable to allow the light to be used alone as a floodlight or with an umbrella reflector. A softbox can be used with either flash or continuous light sources such as fluorescent lamps or "hot lights" such as quartz halogen bulbs or tungsten bulbs. If softbox lights are used with "hot ...
Ground or frosted glass is widely used as a weather- and heat-proof light diffuser in ambient lighting, namely on glass covers or enclosures for lamp fixtures, and sometimes on incandescent bulbs. Its functions include reducing glare and preventing retinal damage by direct sight of the lamp filament.
Standard acrylic diffusers over the fluorescent lamps absorb nearly all the UV-B radiation and appear to protect against this. [26] One paper suggested that in rare cases, fluorescent lighting can also induce depersonalization and derealization; subsequently, it can worsen depersonalization disorder symptoms. [27]
Compact fluorescent mogul-base bulbs are also available, as are adaptors to allow medium-base bulbs to be used in mogul sockets. There are usually two three-way switches near the top of the floor lamp to operate the bulbs. One controls the three-way center bulb, and the other turns on one, two, or all three (or four) of the peripheral bulbs.
