Claim 0:
1. A light adjustment method being implemented electronically by a terminal, the light adjustment method comprising:
determining, by the terminal, an awake time period and a sleep time period of a user, wherein the awake time period and the sleep time period each include at least a first sub-period and/or a second sub-period;
determining, by the terminal, light parameter thresholds in a current time period, wherein the current time period is the awake time period or the sleep time period;
obtaining, by the terminal, a light parameter in the current time period; and
adjusting, by the terminal based on the light parameter and the light parameter thresholds in the current time period, a light parameter of light emitted by a light source device, wherein the light parameter thresholds include a lower light parameter threshold and an upper light parameter threshold, and
adjusting the light parameter of light emitted by the light source device comprises:
if a light parameter in a current sub-period is less than the lower light parameter threshold in the current sub-period, adjusting, by the terminal, the light parameter of light emitted by the light source device, in a next sub-period of the current sub-period, to a first light parameter, wherein the current sub-period includes the first sub-period or the second sub-period, and the first light parameter is greater than the light parameter in the current sub-period; and
if a light parameter in a current sub-period is greater than the upper light parameter threshold in the current sub-period, adjusting, by the terminal, the light parameter of light emitted by the light source device, in a next sub-period of the current sub-period, to a second light parameter, wherein the second light parameter is less than the light parameter in the current sub-period, wherein

the light adjustment method regulates the circadian rhythm of the user; and
the terminal has a light detection function, and the light source device is configured for disposal inside the terminal or configured as an independent device communicating with the terminal.
