As the saying goes, the master is in the folk, this is not a fake, and the master is not divided into grades, the little doll grandfather may create a miracle.
According to Henan TV's "Urban Report" column official micro@urban report, there is a grandfather Liu in Zhengzhou, who got inspiration from the road signal light five years ago and started to turn himself into energy-saving lamps. Now he has finally achieved fruitful results.
Because of the conditions, Liu’s equipment was quite rudimentary. He simply connected the broken bulb to a disc that could reflect light, and then matched it with a resistor to get a homemade “disc lightâ€.
So, what is the effect of this "disc light"? Uncle Liu has installed 40 such disc lights in the corridor of his family's home. The results show that lighting is 12 hours a day, and only consumes one kilowatt hour. Each lamp consumes only 0.6 kWh per day, which is quite energy-saving.
For the old family hospital where Mr. Liu is located, it is very difficult and time-consuming to update the circuit to replace the light bulb. This kind of disc light is simple to make and low in cost, and the effect is not only better than the old incandescent lamp, but also inferior to energy saving. The LED lights, and they don't look ugly, they are quite cool after lighting, it is worth trying. Of course, electrical safety must be professionally inspected and maintained.
Uncle Liu also hopes that by doing so, attract more people to join the thrifty team.
