Abstract:
An embodiment of the disclosure includes a LED module. A substrate is provided. A light sensor is positioned in the substrate. A LED chip is attached to the substrate. The LED chip has a first side and a second side. The second side is covered by an opaque layer with an opening. The opening is substantially aligned with the light sensor. The light sensor receives a light output emitting from the LED chip through the opening.
