Abstract
A light-emitting diode (LED) module and a lamp using the same are provided. The LED module includes a substrate and several light-emitting packages. Each light-emitting package includes an optical wavelength conversion layer and a light-emitting diode having a first light-output surface, a bonding surface, and several second light-output surfaces. The bonding surface is opposite the first light-output surface and connected to the substrate. The second light-output surfaces are between the first light-output surface and the bonding surface. The optical wavelength conversion layer covers the first and second light-output surfaces. The distance between the bonding surface and the top surface of the optical wavelength conversion layer represents a light source thickness. The distance between two adjacent light-emitting packages represents a spacing of light sources. Specifically, the ratio of the spacing of light sources to the light source thickness is between 1 and 6.3.
