Essential Skills for Sales Engineers - LED Lighting

As a qualified sales engineer, the first thing you need to have is to know your own products thoroughly and be familiar with the advantages and disadvantages of your competitors' products. The following is a comprehensive comparison of the various indicators of LED lighting lamps, energy-saving lamps and incandescent lamps, so that sales and consumers have a clear concept of which household lamps to choose.

Item 1: Multi-faceted safety, high efficiency and energy saving

It was Saturday, and Xiao Li got up early in the morning and woke up his wife, ready to "renovate" this small nest. The reason was that his children were coming back from college for the holiday, and they were going to renovate the house to give the children a good mood. He found that several light bulbs in the house were broken, and if necessary, he would replace all of them. Speaking of changing the light bulb, he remembered that he burned his hand when he screwed in the light bulb last time. When he was regretting it, a good friend came to visit. This good friend, Liu, happened to be a technical talent in lighting.

Which kind of home lamps should I choose?

"Da Liu, you're here at the right time. Please recommend a light bulb to me!" "That's easy. Just pick an LED lamp you like." "What lamp? You're not advertising for someone, are you? Nowadays, there are all kinds of tricks to sell things. Wasn't the e-commerce war a few days ago just hype?..." "The LED I'm talking about is not a brand," Da Liu pointed at the incandescent lamp in Xiao Li's hand. "LED is a light emitting diode. It belongs to the fourth generation of electric light sources and has many advantages." "So what are the benefits of it?" Xiao Li's wife joined their conversation when she heard what Da Liu said.

Safer in many ways

"The first point is that LED lamps are safer. Since we use them at home, safety should be the first thing to consider. LED lamps have low temperatures when working, and will not cause burns when accidentally touched, wiped or replaced." "Yes, I got burned the last time I changed that broken lamp," Xiao Li rubbed his right hand, as if he had just been burned, "I always forget about it every time I get burned, alas, I just do it when I'm in a hurry..." "LED is electroluminescence, which means it directly converts electrical energy into light energy. It does not need to convert electrical energy into heat energy like incandescent lamps, and then raise the temperature of the object to emit light, so it will not burn your family." Liu explained.

"Another thing is that LED does not contain harmful substances such as lead, mercury, and cadmium. Of course, I mean that LED lamps produced by regular manufacturers do not contain these harmful substances." Liu continued, "Fluorescent lamps and energy-saving lamps contain mercury vapor. If these lamps are broken, the internal mercury vapor will leak out. Even a small dose can cause damage to the liver, lungs, and brain, and is extremely harmful to the human body and the environment." "It seems that energy-saving lamps are also potentially dangerous," Xiao Li sighed, "If you think about it this way, you have to change to L... uh..."

"LED lights," Liu continued, "and LED lights have no flicker, no ultraviolet and infrared radiation, eliminating the visual fatigue caused by the flicker of traditional light sources. In other words, LED lights have no light pollution, no harm to the human body, and no radiation."

High light efficiency determines energy saving

Xiao Li tapped the table with his fingers, thinking of the issue of energy saving: "Da Liu, do you think that LED lamps are more energy-efficient than energy-saving lamps?" "Yes, the high luminous efficiency of LED lamps determines its excellent performance in energy saving. The luminous efficiency of incandescent lamps is only 10-15lm/W, the luminous efficiency of fluorescent lamps is about 70lm/W, and the luminous efficiency of LED lamps can reach 90-120lm/W. With the advancement of technology, its luminous efficiency will be further increased." Xiao Li took out a pen from under the coffee table and wrote on the paper, indicating that he did not understand the luminous efficiency yet.

Energy consumption comparison of three types of lamps

Liu explained: "High light efficiency means energy saving for ordinary families. A 5W LED lamp can replace a 40W incandescent lamp or a 10W fluorescent lamp. The energy saving advantage is still very obvious." Liu took the pen and paper and began to write a comparison of the three light sources: "Based on 4 hours of use per day, incandescent lamps consume 58.4 kWh of electricity per year, energy-saving lamps consume 14.6 kWh of electricity, and LED lamps consume 7.3 kWh of electricity; our community costs 4.8 yuan per kilowatt-hour, so the electricity bill is: 28 yuan for incandescent lamps, 7 yuan for energy-saving lamps, and 3.5 yuan for LED lamps." "It doesn't seem to save much energy in this way. It doesn't save much money in a year." Xiao Li said. "Of course, the above is only the calculation of a single bulb. The more bulbs there are, the more obvious the energy saving will be. And this energy saving must also be combined with the advantage I will talk about below."

Item 2: Long life, humanized and more reliable

Long life cannot be ignored

"Another big advantage of LED lamps is their long lifespan: Incandescent lamps have a lifespan of about 1,000 to 2,000 hours, fluorescent lamps have a lifespan of about 10,000 hours, and LED lamps can last up to 50,000 hours. For a family like ours that uses the light bulbs for four hours a day, your son will probably be the next person to replace the light bulb after you replace the LED lamps!" "Haha, that really saves a lot of trouble," Xiao Li laughed. "Such a long lifespan saves you the trouble of replacing the light bulbs and the cost of buying new ones, so the ultra-long lifespan is an advantage of LED lamps that cannot be ignored."

Humanized and highly reliable

"With so many advantages, will it be very delicate?" Xiao Li was a little worried. Da Liu patted him on the shoulder and said, "You don't have to worry about this. LED is solid-state lighting, so it is also highly stable and not easily affected. It can withstand greater shocks than other lamps. In addition, the size of LED is very small, which makes LED lamps highly applicable and easy to make into various shapes. At the same time, different technologies can be used to change the color of LED lamps, so it can better add luster to home lighting and is more suitable for modern home lighting."

Combining the above two major projects to analyze these three lamps, the advantages of LED are clear at a glance.
