The advantages and comparison of LED lights
For general lighting, people need more white light sources. In 1998, white light-emitting LEDs were successfully developed. The LED is made by encapsulating a GaN chip with yttrium aluminum garnet (YAG). The GaN chip emits blue light (λp=465nm, Wd=30nm), and the Ce3+-containing YAG phosphor made by high temperature sintering is excited by this blue light and emits yellow light emission with a peak value of 550nm. The blue LED substrate is mounted in a bowl-shaped reflective cavity, covered with a thin layer of resin mixed with YAG, about 200-500nm. Part of the blue light emitted by the LED substrate is absorbed by the phosphor, and the other part of the blue light is mixed with the yellow light emitted by the phosphor to obtain white light. For InGaN/YAG white LEDs, by changing the chemical composition of the YAG phosphor and adjusting the thickness of the phosphor layer, various colors of white light with a color temperature of 3500-10000K can be obtained. Advantage 1. High efficiency and energy saving
It only consumes a few kWh of electricity for 1,000 hours (ordinary 60W incandescent lamps consume 1 kWh of electricity for 17 hours, and ordinary 10W energy-saving lamps consume 1 kWh of electricity for 100 hours)
2. Super long life
The semiconductor chip emits light, no filament, no glass bubble, not afraid of vibration, not easy to break, and the service life can reach 50,000 hours (the service life of ordinary incandescent lamps is only 1,000 hours, and the service life of ordinary energy-saving lamps is only 8,000 hours)
3. Health
Healthy light The light does not contain ultraviolet and infrared rays, and does not produce radiation (ordinary light rays contain ultraviolet and infrared rays)
4. Green environmental protection:
It does not contain harmful elements such as mercury and xenon, which is conducive to recycling and does 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. Protect your eyesight
DC drive, no stroboscopic (ordinary lights are AC driven, it will inevitably produce stroboscopic)
6. High light efficiency
Low heat generation, 90% of the electric energy is converted into visible light (80% of the electric energy of ordinary incandescent lamps is converted into heat energy, and only 20% of the electric energy is converted into light energy)
7. High safety factor
The required voltage and current are small, the heat generation is small, and there is no potential safety hazard. It can be used in dangerous places such as mines.
8. Great market potential
Low-voltage, DC power supply, battery, solar power supply, in remote mountainous areas and outdoor lighting and other places with low electricity and low electricity. Contrast 1. LED lights have the same stroboscopic phenomenon as ordinary incandescent lamps when driven by alternating current, while ordinary energy-saving lamps have no stroboscopic phenomenon. Strobe light can easily tire the eyes.
2. The light of each LED bulb is too bright, which will strongly irritate the eyes. Do not look directly at it, even for a short time, while ordinary energy-saving lamps are relatively softer!
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 illuminated room is not better than that of energy-saving lamps, because the LED has high brightness only in a narrow angle of direct viewing, and the light rapidly weakens after deviating from this angle. Therefore, the advantages of LED energy-saving lamps as indoor lighting lamps may not be more obvious than ordinary energy-saving lamps, but they are still very good when used as lamps, such as torches, desk lamps, and spotlights, which only need to illuminate a narrow angle.
