Light emitting device with LED chip

A LED chip component includes a heat sink substrate made of high thermal conductivity coefficient and at least a LED chip. The heat sink substrate includes a reflecting mirror having a central portion and a reflecting portion surrounding the central portion, a normal of a top surface of the reflecting portion forming an acute angle relative to a normal of a top surface of the central portion, the LED chip unitarily connected with the central portion, wherein a method for manufacturing the LED chip component includes a chip setting step, a sacrificial layer forming step, a heat sink substrate forming step, and a sacrificial layer removing step, the chip setting step further including a packaging method for packaging the LED chip without preforming connecting points on the LED chip to connect with external circuits. The LED chip component with the heat sink substrate improves heat dissipation and working duration.
