There are a variety of artificial lights, including LEDs, incandescents and gaseous discharge. Artificial light is that which people have created in order to provide illumination for buildings.Know More
LEDs (light emitting diodes) can provide different colored light. These vary from shades like white to ones like blue, red, and green. RGB lights combine different color sources into one. These are still a newer light source than other types of artificial lights.
One of the most common light sources, incandescent bulbs provide illumination through a filament within the bulb. Halogen lamps are also a type of incandescent that use halogen gas. Fluorescents also burn gas to function.
Gaseous discharge lights work similarly to halogen lights. They utilize gas to provide illumination. High-intensity discharge lights or HIDs are also a type of gaseous discharge light that use gases such as metal halide, high pressure sodium, and mercury vapor to provide illumination.Learn more about Lighting
A light bulb is non-ohmic because it does not obey Ohm’s law. According to Ohm's law, "The ratio of potential difference to the current flowing through a conductor is constant, providing all other influences such as temperature are kept constant."Full Answer >
Monochromatic light refers to light that is of one color. Since it only emits one color, monochromatic light has a single wavelength. Wavelengths are seen as a rainbow of colors when light is passed through a spectrum. Therefore, monochromatic light would emit just one of these colors.Full Answer >
An incandescent light bulb uses electricity to heat up a tungsten wire encased in a glass shell until it glows. Because this light source also gives off heat, it is often used in incubators and lava lamps and to speed the drying process.Full Answer >
LED stands for light–emitting diodes, which are semiconductor devices that produce visible light when an electrical current passes through them. LED lighting is different from incandescent and compact fluorescent lighting in that it is more durable, longer-lasting and more energy efficient.Full Answer >
