Abstract
A light-emitting diode module includes a transparent base, a support and a plurality of light-emitting chips. The base has a plurality of cavities separated from each other by a predetermined distance in order to respectively receive the light-emitting chips to form light-exiting areas. The base has a reflecting portion opposite to the cavities. The reflecting portion is at least one inclined plane for reflecting light that have projected outside walls of the cavities to the peripheral area of the light-emitting areas in order to increase the uniformity of the light source. In addition, the light-emitting chips are arranged to form a line or surface light source of any sizes by adjusting the numbers of the cavity and the light-emitting chips.
