(1), high light efficiency: high energy conversion efficiency under low luminosity (the efficiency of converting electrical energy into light energy)-that is, more power saving, very suitable for low luminosity (such as mobile phone backlight, night light) needs Used in. However, when the luminosity is increased to be like a desk lamp or higher, the efficiency of LED is higher than that of tungsten bulbs, but worse than fluorescent lamps (commonly known as light tubes or fluorescent tubes): IEEE (Institute of Electrical and Electronics Engineers) publication IEEESpectrum once An article confirms this.
(2) Fast response: short response (switching) time-can reach a high flashing frequency, and even make "visible light network" possible.
(3) Long service life: Long service life-the service life will not be affected by continuous flashing, and it can reach 35,000 to 50,000 hours under proper heat dissipation and environment (fluorescent lamp is 10,000 to 15,000 hours , Incandescent lamp is 1,000 to 2,000 hours).
(4). Anti-vibration: resistance to mechanical shocks such as vibration-because it is a solid-state component, there is no filament, glass cover, etc., compared with fluorescent lamps, incandescent lamps, etc., it can withstand greater vibration.
(5), easy to focus-because the light-emitting volume is small, it is easy to achieve the required degree of collection and dispersion by means of lenses, etc., by changing the package shape, the light-emitting angle can be achieved from large angle scattering to fine angle focusing.
(6), many colors: the color gamut is slightly wider-some white LEDs cover a wider color gamut than other white light sources.
(7), strong monochromaticity-because it is a photon from a single energy level, the wavelength is relatively single (relative to most artificial light sources), and it can provide a variety of simple colors without filters.
(8) Small size-its volume can be made very small (less than 2mm).
