◆Long life span（＞100，000HRS）
◆Low driving voltage（1.8—4.5V）
◆Low power consumption（40~100mW）
◆Relatively cold light source
◆Light speed (time constant of 10-7-10-9S)
◆To avoid the suspected lighting effect
◆ Small
◆ a variety of colors
◆ Shock resistance particularly good (all-solid package, not easy to break)
◆ Monochromatic nature (light-emitting wavelength stability)
◆ Green pollution-free
