Patent attributes
Various embodiments relate to the field of communications technologies, and provide a light adjustment method and a terminal to resolve a problem that an existing light therapy device cannot flexibly adjust light based on a light requirement of a user and cannot more intelligently adjust a circadian rhythm of the user. In those embodiments, an awake time period and a sleep time period of a user is determined by the terminal, and parameter thresholds in the awake time period and the sleep time period is determined by the terminal. In those embodiments, a light parameter in a current time period is obtain by the terminal, and based on the light parameter in the current time period, a light parameter of light emitted by a light source device is then adjusted by the terminal.
