Zhang Dexi invented LED electronic energy-saving lamps and obtained national patents

As the first Shanghai World Expo to propose the concept of “low carbon Expo”, the Expo Park has become a large booth and laboratory for green and low-carbon technology products, and energy-saving LED lights have become a highlight of the low-carbon Expo. At present, about 80% of the indoor lighting sources in the Expo venues use LED green light sources, which is about 90% less than ordinary incandescent lamps.

Is the LED light in the Expo Garden energy-efficient? The LED electronic energy-saving lamps invented by Zhang Dexi in Kezhen City are not inferior and have obtained national patents. The 1.5W LED electronic energy-saving lamp is equivalent to the brightness of the fluorescent electronic energy-saving lamp 5W~7W, which is equivalent to the brightness of the incandescent lamp 25W.


Very energy efficient and safe


Zhang Dexi is a retired worker in Aizhuang Village, Qiqiao Town, Qibin District. Before retiring, he worked on electrical energy-saving technology. After retirement, he developed LED electronic energy-saving lamps. The LED electronic energy-saving lamps he invented have obtained national patents.


On May 10th, the author came to Zhang Dexi's house. When I entered the door, the author was attracted by the light bulbs everywhere in the house. There were all kinds of energy-saving lamps everywhere on the table and coffee table.


Zhang Dexi picked up a self-invented energy-saving lamp and introduced it to the author. The 1.5W LED electronic energy-saving lamp he invented is equivalent to the brightness of fluorescent electronic energy-saving lamps 5W~7W, equivalent to the brightness of incandescent lamps 25W, 1.5W LED electronic energy-saving The lamp can be used for normal room lighting. Zhang Dexi also found the instrument and tested the brightness of the lamp on site.


"In fact, there are a lot of electricity that can be saved around us without saving. Just like the corridor lights of residential buildings, it can be improved and save a lot of electricity." Zhang Dexi said that the current energy-saving lamps can not be used in the corridor because The lamp is not right, and the incandescent lamp can only be installed in the corridor if it is more than 40W. To this end, Zhang Dexi specially developed a LED electronic energy-saving lamp for corridor lighting and courtyard lighting. The corridor lighting only needs 0.5W, and the courtyard lighting only needs 3W.


“The lamp I invented is not only energy-saving, but also very safe.” Zhang Dexi said that this LED electronic energy-saving lamp is not easy to break. “Unless you knock with a small hammer, it will not break easily.”


After numerous experiments


Zhang Dexi said that he mainly worked on electrical energy-saving technologies before he retired. In 2006, he had the idea of ​​making LED electronic energy-saving lamps. With this in mind, he began to investigate in the market and learn about the LED lights in the market. "I will go to the market if I have nothing to do. As soon as I find the LED lights, I will buy them back and take a look at how others do it."


After investigation, Zhang Dexi found that in addition to tubular or spiral ordinary fluorescent energy-saving lamps, there are many brands of LED energy-saving lamps on the market, but these lamps are still incomplete. "The LED energy-saving lamps sold on the market still have the disadvantages of high heat loss and high material cost. I have been working on heat loss, and after reducing heat loss, energy-saving lamps will be more energy-efficient." Zhang Dexi told the author.


Zhang Dexi not only went to the coastal market where there were more energy-saving lamps, but also helped his friends to help him pay attention. With the idea of ​​perfecting energy-saving lamps, Zhang Dexi is full of energy-saving lamps. Not only when he wants to eat, but when he sleeps, he even thinks that he can't even talk about energy-saving lamps. Sometimes he sleeps until he thinks about it in the middle of the night. It’s the point of “getting out of the fire”. After many experiments, Zhang Dexi finally invented a new LED electronic energy-saving lamp.


After developing such an LED electronic energy-saving lamp, Zhang Dexi sent a light bulb to others, hoping that relatives and friends would share his victory. After the successful development of his LED electronic energy-saving lamp, he applied for a patent to the China Intellectual Property Office in 2009. Obtained national patents.


Zhang Dexi said: "My LED electronic energy-saving lamps are different from the energy-saving lamps on the market, which reduces the heat loss a lot."


Zhang Dexi also specially developed remote-controlled LED electronic energy-saving lamps for the elderly. This kind of light bulb can be controlled by the remote control of air conditioner, TV or DVD player. The remote control can turn the light bulb on or off. It is suitable for elderly people with limited mobility. .


Zhang Dexi said that in addition to the 0.5W corridor LED electronic energy-saving lamp, 3W courtyard electronic energy-saving lamp and 1W room lighting electronic energy-saving lamp, he now pays attention to the electric rod for student learning. "Now the electric bars in the classroom have strobes, the students have poor eyesight, and the school's electricity consumption is also very large, so I am now studying a classroom-specific lamp that can help the school save electricity and protect students. Vision." Zhang Dexi said to the author.
