Abstract
A lamp having a first illumination module, a second illumination module and a control circuit is provided. The first illumination module has a first light-emitting surface, and the second illumination module has a second light-emitting surface connected to the first light-emitting surface. The control circuit is coupled to the first illumination module and the second illumination module. When the control circuit increases the luminance of the first illumination module and the luminance of the second illumination module, a percentage of increasing the luminance of the first illumination module is less than a percentage of increasing the luminance the second illumination module.
