LEDs provide monochromatic light with a wide half-width. Because the bandgap of a semiconductor decreases with increasing temperature, the peak wavelength of its emission increases with temperature, a phenomenon known as spectral redshift, with a temperature coefficient of +2~3 A/s. The luminous intensity (L) of an LED is approximately proportional to the forward current. As the current increases, the luminous intensity also increases approximately.
LED grid lights are devices used for illumination.
These devices can be divided into recessed and surface-mounted models. Based on the reflector style, they are divided into I-type and V-type. Different reflectors differ significantly in aesthetics and reflective effect. Generally, V-type reflectors are superior to I-type in both aesthetics and reflective effect, with little price difference. Distinguishing between I-type and V-type is very easy; they can usually be identified visually.
