It is a lamp that requires us to exchange our belongings for lights. We put our belongings on the light fixture tray and the light fixture is turned on. On the one hand, through this sense of exchange, we can feel the value of energy sources, so as to subconsciously remind us to take actions to save the limited energy sources. It's like a child trading a beloved toy for a lollipop. On the other hand, when we leave, we can easily pick up the objects on the tray to turn off the light, which solves the problem that we often forget to turn off the light.
