助眠唤醒灯 / Sleep&Wake up Lamp

This is a bed lamp which can change the intensity of light automatically with time.The color of the inner wall of the lampshade changes gradually from white to black, and the light bulb is installed on the hour hand of a clock. The light irradiates the inner wall and reflects to the room. With the rotation of the hour hand of the clock, the color of the inner wall illuminated by light will vary from white to black, so the reflectivity will decrease. The lower the reflectivity, the weaker the intensity of light in the room, so we can enjoy our sleeping in the environment of gradually changing light.
