Advantages of LED light
1, energy efficient: one thousand
hours power consumption of only a few degrees (normal 60W incandescent seventeen
hours of electricity consumption, ordinary 10W energy-saving lamps one hundred
hours of electricity consumption)
2, long life: light-emitting
semiconductor chips, no filament, no glass bulb, afraid of shock, not broken,
the service life up to 50,000 hours (incandescent life of only one thousand
hours, ordinary energy-saving lamp life of only eight one thousand hours)
3 Health: Healthy light contain
ultraviolet and infrared light, no radiation (ordinary light contains
ultraviolet and infrared)
4, green: no mercury and xenon
and other harmful elements, conducive to recovery and, and will not produce
electromagnetic interference (ordinary lamp contains mercury and lead elements,
energy-saving lamps, electronic ballasts will produce electromagnetic
5, protect eyesight: DC drive, no
flash (normal lights are AC drive, it will inevitably produce strobe)
6, high light efficiency: heat a
small, 90% of the electrical energy into visible light (80% of the ordinary
incandescent electric energy into heat, only 20% of electrical energy into light
7, high safety factor: the
required voltage, current, smaller, less heat, no security risks, in mines and
other dangerous places
8, the market potential: Low
voltage, DC power supply, battery, solar power, in remote mountainous areas and
outdoor lighting, electricity, less electricity places.
Contrast that with incandescent
LED lights 1, led lights in AC-driven and will flicker as ordinary incandescent
lamps, while the ordinary energy-saving lamps do not flicker. Strobe cause eye fatigue.
2, each led bulb light is too
bright, strongly irritating to the eyes, can not look, even a short time, while
the ordinary energy-saving lamps are relatively softer!
3, the irradiation angle is
limited, generally only irradiation 120 °, while the ordinary energy-saving
lamps illuminated almost 360 °.
4, the brightness of the room
illumination is not better than energy-saving lamps, because there is a high
brightness led only look at the narrow point of view, while the deviation of the
angle of light weakened rapidly.
Thus, led energy saving lamps
advantages as indoor lighting may not be significantly higher than the ordinary
energy-saving lamps, but when used as a flashlight, lamps, spotlights, etc. Just
narrow angle illumination lamps still very good.
