1, LED lamp is efficient and energy-saving: only a few kwh is consumed in one thousand hours (ordinary 60W incandescent lamp consumes 17 hours 1 kwh, ordinary 10W energy-saving lamp consumes 100 hours 1 kwh).
2. Long life of 2.LED lamp: the semiconductor chip emits light, has no filament, no glass bubbles, is not afraid of vibration and is not easy to break, and its life can reach 50,000 hours (the life of ordinary incandescent lamps is only/kloc-0.000 hours, and that of ordinary energy-saving lamps is only 8,000 hours).
3.LED lights are healthy: light is healthy. Light does not contain ultraviolet rays and infrared rays, and does not produce radiation (ordinary lamps contain ultraviolet rays and infrared rays).
4.LED lamp is environmentally friendly: it does not contain harmful elements such as mercury and xenon, which is conducive to recycling and will not produce electromagnetic interference (ordinary lamps contain elements such as mercury and lead, and electronic ballasts in energy-saving lamps will produce electromagnetic interference).
5, LED lights to protect vision: DC-driven, no stroboscopic (ordinary lamps are AC-driven, stroboscopic will inevitably occur)
6.LED lighting efficiency is high: it generates less heat, and 90% of electric energy is converted into visible light (80% of electric energy of ordinary incandescent lamps is converted into heat energy, and only 20% of electric energy is converted into light energy).
7. The 7.LED lamp has high safety factor: the required voltage and current are small, and the heat generation is small, which will not cause potential safety hazards and is used in dangerous places such as mines.
8.LED lamps have great market potential: low voltage, DC power supply, battery and solar power supply, which are used in remote mountainous areas, outdoor lighting and other places where electricity is tight.
Disadvantages of led lamp:
1, LED lights will flash like ordinary incandescent lamps when driven by alternating current, but ordinary energy-saving lamps will not. Flash will make your eyes tired easily.
2, the light of each led bulb is too bright, which will strongly stimulate the eyes, and you can't look straight, even for a short time, while ordinary energy-saving lamps are relatively soft!
3. The irradiation angle is limited, generally only 120 can be irradiated, while ordinary energy-saving lamps can almost irradiate 360.
4. The brightness of the room is not better than that of the energy-saving lamp, because the led has high brightness only at a narrow direct viewing angle, and the light will soon weaken after deviating from this angle.
