Abstract: A lighting module with high rending property includes a substrate, a plurality of first light emitting diode (LED) chips, a plurality of second LED chips and a wavelength conversion layer. The first LED chips are deposed on the substrate and electrically connected to the substrate. The second LED chips are deposed on the substrate and electrically connected to the substrate. The wavelength conversion layer seals the first LED chips and the second LED chips. The light emitted from the LED chips and the light emitted from the wavelength conversion layer caused by an excitation by the LED chips are mixing to form warm white light with high color rending property. The number ratio of the first LED chips to the second LED chips deposed on the substrate is 2:1.

Abstract: A testing method for a LED module and its associated elements includes the steps of: providing a LED module on which a plurality of light-emitting diodes is arranged; providing an integration detector, and mounting it above the LED module; providing an electrically conducting means having a plurality of conductive terminals and an electronic signal connector electrically connected to the conductive terminals; electrically connecting the light-emitting diodes with the conductive terminals; using the electronic signal connector to change the ON/OFF states of the electrical signals of the light-emitting diodes and the conductive terminals; and detecting the photo-electrical properties of each light-emitting diode via the integration detector.
