Abstract:
1. A multichip package structure, comprising: a metal substrate having a first mirror plane area and a second mirror plane area, wherein the first mirror plane area and the second mirror plane area are disposed on the top surface of the metal substrate, and the first mirror plane area and the second mirror plane area are separated from each other by a predetermined distance; a circuit substrate disposed on the metal substrate, wherein the circuit substrate includes a plurality of first conductive pads applied to the first mirror plane area, a plurality of second conductive pads applied to the first mirror plane area, a first passing opening for exposing the first mirror plane area, and a second passing opening for exposing the second mirror plane area; a light-emitting module including a plurality of light-emitting units disposed on the first mirror plane area, wherein each light-emitting unit includes a plurality of LED chips disposed on the first mirror plane area, and the LED chips of each light-emitting unit are electrically connected between the first conductive pad and the second conductive pad in series; a current-limiting module including a plurality of current-limiting chips disposed on the second mirror plane area and electrically connected to the light-emitting module; a frame unit including a first surrounding gel frame and a second surrounding gel frame, wherein the first surrounding gel frame is surroundingly disposed on the circuit substrate by coating to form a first gel position limiting space, the second surrounding gel frame is surroundingly disposed on the circuit substrate by coating to form a second gel position limiting space, and the light-emitting module and the current-limiting module are respectively surrounded by the first surrounding gel frame and the second surrounding gel frame; and a package unit including a first package gel body and a second package gel body, wherein the first package gel body is received in the first gel position limiting space to enclose the light-emitting module, and the second package gel body is received in the second gel position limiting space to enclose the current-limiting module.
