Item 1: Multi-faceted, safe and energy efficient

This day is Saturday, Xiao Li wakes up in the morning to wake up his wife, ready to give this small nest a "full capacity." The reason is that his children are going to college to go back on holiday, they are ready to refresh their homes and give their children a good mood. He found that several of the bulbs in the house had broken down, and if necessary, changed all of them. When it comes to changing the light bulb, he remembers that his hand was burnt when the light bulb was screwed last time. When he was remorseful, just a friend came to the door. To say that this friend, Da Liu, is precisely a technical talent in lighting.

Which kind of household lighting chooses?

"Big Liu, you come right, help me recommend a light bulb!" "This is simple, you pick a favorite LED light." "What light is L? You are not advertising to others? But the pattern is full, the e-commerce wars of the past few days are not hype..." "I said LED is not a brand," Da Liu pointed to the incandescent lamp in Xiao Li's hand. "LED is a light-emitting diode. Belonging to the fourth generation of electric light source, it has many advantages. "Whether it has all the advantages?" Xiao Li’s wife heard that Liu Liu said that he also joined their conversation.

"The first point is that LED lights are safer. Let's use our own home. Safety should be the first consideration. LED lights are low in temperature during operation, and will not be burnt when accidentally touched and wiped or replaced." Yes, I was burnt when I changed the broken lamp last time." Xiao Li licked his right hand, as if he had just been burnt. "Every time I was burned, I forgot it, oh, I’m going to get started quickly..." LED is electroluminescence, that is, it directly converts electric energy into light energy. It does not need to convert electric energy into heat energy like incandescent lamp, so that the temperature of the object rises to illuminate, so it will not burn to the family." Da Liu explained.

"One more, LEDs do not contain harmful substances such as lead, mercury, cadmium, etc. Of course, I said that the LED lamps produced by regular manufacturers do not contain these harmful substances." Da Liu continued, "Fluorescent lamps and energy-saving lamps contain mercury." Steam, the breakdown of these lamps will cause internal mercury vapor to leak, even small doses will cause damage to the liver, lungs and brain, which is extremely harmful to the human body and the environment." "It seems that energy-saving lamps are also potentially dangerous. Ah," Xiao Li sighed. "If you think about it, you have to change L... oh..."

"LED lights." Da Liu continued, "and the LED lights have no stroboscopic, no ultraviolet and infrared radiation, eliminating the visual fatigue caused by the stroboscopic light source. In other words, the LED lights have no light pollution, on the human body. No damage, no radiation."
