Korean designer Jongwoo Choi has designed the innovative and energy-saving Secret Lamp. In designer’s words, “If we fall asleep without noticing that the light is still on or we cause energy waste due to our unnecessary use, it might results in serious environmental issue. This ‘Secret Lamp’ will contribute to solving some environmental issues because it is able to adjust the amount of light as much as you need and it also can generate nightglow light with accumulated power.”
