Energy-saving lighting equipment (picture from demohour)
London-based designers Jim Reeves and Martin Reddiford have developed a lighting solution specifically for families in developing countries. This solution is cheap, unlike traditional power outlets and expensive solar power. The LED light, called GravityLight, does not require a charging power supply at all, and it means no cost.
The GravityLight is equipped with several pulleys and a well-designed powertrain, with a nostalgic counterweight that uses gravity to generate electricity. The entire power generation process of GravityLight is such that the weights are referred to the upper air and then converted into electricity by the power gained. It can be slowly lowered, and the energy of illuminating for 30 minutes. Since there is no electricity, the initial investment is almost zero and no garbage is generated.
At the same time, this GravityLight can even charge other devices. Devices that require recharge can be connected to an interface on the GravityLight front panel. It is even possible to adjust the brightness of the GravityLight bulb to suit the user's needs, thus extending the use time.
It is reported that the cost of this GravityLight bulb is less than 5 US dollars (about 31 yuan). Undoubtedly, once the GravityLight bulb is officially launched, its low price and simple operation will definitely attract many consumers.
Along with the rapid development of technology, household products began to transform into intelligence, such as smart sockets, smart curtains, intelligent lighting, etc., not only eliminating the complicated operation process in life, but also enhancing the safety of the home. Similarly, there are also good improvements in energy consumption, such as the product below, designed for home users in developing countries.
