Abstract

Various embodiments may relate to an LED module, including a number of first inherently unpackaged LED chips, which are in each case designed to emit light of a first color at a respective light emission area, and a number of second inherently unpackaged LED chips, which are in each case designed to emit light of a second color, different than the first color, at a respective light emission area. The LED chips are provided jointly in a housing, and the respective light emission area of a second LED chip is at least 25% smaller than the respective light emission area of a first LED chip. The sum of the light emission areas of the first LED chips is at least 50% greater than the sum of the light emission areas of the second LED chips.
