Optical Characteristics Of LED Spotlights

LED spotlights are spotlights that use light-emitting diodes as light sources. Traditional spotlights mostly use halogen lamps, which have low luminous efficiency, high power consumption, rising ambient temperature, and short service life. LEDs are far superior to traditional lighting products in terms of luminous principle, energy saving, and environmental protection. Moreover, the unidirectional nature of LED light emission forms a perfect support for spotlight light distribution.
LEDs provide monochromatic light with a large half-width. Since the energy gap of semiconductors decreases with increasing temperature, the peak wavelength it emits increases with increasing temperature, that is, the spectrum redshifts, and the temperature coefficient is +2~3A/ . The LED luminous brightness L is approximately proportional to the forward current. As the current increases, the luminous brightness also increases approximately.
