Abstract

An intelligent type lamp and a vehicle lamp apparatus are disclosed. The lamp includes a first substrate, a second substrate disposed on the first substrate, and a plurality of light sources disposed on the second substrate, wherein the light sources are grouped into at least one light source array, in each of which the light sources are disposed in a line, and the at least one light source array includes neighboring first and second light source arrays electrically isolated and individually driven. The light sources of the first light source array may be electrically isolated and individually driven, and the light sources of the second light source array may be electrically isolated and individually driven. Alternatively, the light sources of the first light source array may be electrically isolated and individually driven, and the light sources of the second light source array may be electrically connected and simultaneously driven.
