LEDs are used more and more widely in our lives. Outdoor street lights, buried lights, lawn lights, underwater lights, stage lights... It can be said that LEDs are everywhere. As indoor lighting, LED lights are everyone's "hot". why? Because it's okay. Gold is not enough, people are not perfect, LED naturally has some shortcomings. Here are eight advantages and seven shortcomings of LED lights.
First, LED lights: eight advantages, it is worth having
1, low power consumption, durable and durable
The LED lamp consumes less than one-third of the power of traditional fluorescent lamps and has a lifetime that is 10 times that of traditional fluorescent lamps. It can be used for a long period of time without replacement, reducing labor costs. More suitable for difficult to replace occasions.
2, green lighting, protect the environment
Traditional lamps contain large amounts of mercury vapor, which can evaporate into the atmosphere if the mercury vapor is broken. However, LED lamps do not use mercury at all, and LED products do not contain lead, which protects the environment. LED lights are recognized as the green lighting of the 21st century.
3, will not blink, love eyes
Traditional lamps use alternating current, so they produce 100-120 strobes per second. LED luminaires convert AC power directly to DC power without flickering and protecting the eyes.
4, no noise, quiet choice
LED lamps do not produce noise and are a good choice for applications where precision electronic equipment is used. Suitable for libraries, offices and the like.
5, no UV, mosquitoes do not love
LED lamps do not produce ultraviolet light, so there are not many mosquitoes that surround the light source like conventional lamps. The interior will be cleaner and tidy.
6, efficient conversion, save energy
Traditional lamps and lanterns will produce a lot of heat, and LED lamps and lanterns are all converted into light energy energy, will not cause a waste of energy. And for documents, clothes will not fade.
7, no fear of voltage, adjust the brightness
The traditional fluorescent lamp is lit by the high voltage released by the rectifier, and cannot be turned on when the voltage is reduced. The LED lamps can be lighted within a certain range of voltage, but also adjust the brightness.
8, strong and reliable, long-term use
The LED lamp body itself uses epoxy resin instead of traditional glass, which is more firm and reliable, and even if the LED is not easily damaged on the floor, it can be safely used.
Second, poor LED lights: seven advantages, not perfect
1. The LED lamp has stroboscopic phenomenon driven by the alternating current, and the stroboscopic light will make the eyes easily fatigued;
2, a single LED power is low, in order to obtain high power, you need to use multiple parallel;
3, due to defects in the manufacturing process of the white LED itself coupled with the reflection cup or lens error, easily lead to "yellow circle" problem;
4, the brightness of the illuminated room is not better than the energy-saving lamps, because led only in the narrow angle of the direct view of high brightness, and the deviation from the angle after the light quickly weakened;
5, compared to incandescent lamps, led lighting is relatively high, but the light is too bright will stimulate the eyes;
6. The color rendering index is low, and the color displayed under the LED illumination does not have an incandescent lamp;
7, there is a limit to the irradiation angle, generally only 120 °.
