LED lamp is another type of lamp of various style and concept use for any buildings that is cost effective and energy efficient lighting system. According to Wikipedia: “A LED lamp is a light-emitting diode (LED) product that is assembled into a lamp for use in lighting fixtures.
LED lamps offer comparatively long life compared to incandescent lamps and some fluorescent, although at a higher initial expense. Degradation of LED die and packaging materials reduces output over time. General-purpose lighting needs white light. LEDs emit light in a very small band of wavelengths, emitting light of a color characteristic of the energybandgap of the semiconductor material used to make the LED. To emit white light from LEDs requires either mixing light from red, green, and blue LEDs, or using a phosphor to convert some of the light to other colors.”
