Incandescent light spectrum chart
WebAn incandescent light bulb creates a continuous visible spectrum because the source of the light is a metal filament. The visible light spectrum is a range of wavelengths that the … WebThere are at least three approaches that could be taken about the ideal frequencies that CFL bulbs should have: 1. Match the visual spectrum of the human eye. 2. Match the spectrum of IL bulbs. 3. Match the solar spectrum. One could argue that #1. is the most important.

In practice, virtually all solid or liquid substances start to glow around 798 K (525 °C; 977 °F), with a mildly dull red color, whether or not a chemical reaction takes place that produces light as a result of an exothermic process. This limit is called the Draper point. The incandescence does not vanish below that temperature, but it is too weak in the visible spectrum to be perceptible. At higher temperatures, the substance becomes brighter and its color changes from red toward…
