LIGHT-EMITTING DEVICE MODULE, AND SURFACE-EMITTING APPARATUS

摘要

PURPOSE: A light emitting device module and a surface light source device are provided to obtain a uniform color temperature regardless of the deviation of an individual device or the change of a manufacturing process. CONSTITUTION: A light emitting device package(110) includes a first light emitting device(112) and a second light emitting device(113). The first light emitting device emits light with a peak wavelength at a specific color. The second light emitting device controls the intensity of radiation according to a current of a driving source. A driving control unit(120) includes a first driving circuit(121) and a second driving circuit(122). The first driving circuit changes a color temperature by controlling the current applied to the first light emitting device. The second driving circuit changes a color temperature by controlling the current applied to the second light emitting device. [Reference numerals] (121) Driving circuit 1; (122) Driving circuit 2
