Abstract: The project explores the harmful effects of excessive light exposure at night and people’s sleeping habits. Most people would use electronic devices in bed for a long time before sleep, and sometimes we fall asleep and accidentally leave the light on all night. And there are also some people who are afraid of darkness prefer to sleep with the light on all night. Sleeping with the light on deliberately or unintentionally and playing electronic devices in bed are both bad sleeping habits that would lead to poor sleep quality and affect our health. However, due to the fear of darkness, people feel safer to keep the light on when sleeping, and sometimes, we fall asleep and accidentally leave the light on; it is also hard for people to stop using electronic devices in bed. So, how can I help those people who are afraid of darkness sleep night and avoid leaving the light on all night during sleep and how can I make people who use long-time electronic devices in bed aware of it is time to sleep? During the research, I found that lights off can be used as a signal to remind people to sleep. The final design is a bedside lamp with a timer that can be timed through physical interaction without using apps or remote control and showing time passing intuitvely.
