Abstract:
1. A light emitting diode (LED) package comprising: a silicon substrate; a photo diode formed in an upper part of the silicon substrate; an insulation layer formed on the silicon substrate excluding at least a light-receiving area of the photo diode; a photo diode connecting terminal formed on the insulation layer to be connected to the photo diode; first and second LED connecting pads formed on the insulation layer, and arranged on both sides of the photo diode; a partially reflective film comprising an insulating material having a low light transmittance to provide desired light quantity and formed on the photo diode; and an LED chip mounted on the partially reflective film, and connected to the first and second LED connecting pads, wherein the partially reflective film is located between the LED chip and the photo diode so that the amount of light that reaches from the LED chip to the photo diode is controlled by the partially reflective film.
