LED package structures for preventing lateral light leakage and method of manufacturing the same

摘要

An LED package structure (Z) for preventing lateral light leakage includes a substrate unit (1), a light-emitting unit (2), a light-transmitting unit (3) and a light-shielding unit (4). The substrate unit (1) includes a circuit substrate (10). The light-emitting unit (2) includes at least one LED chip (20) disposed on the circuit substrate (10) and electrically connected to the circuit substrate (10). The light-transmitting unit (3) includes a light-transmitting gel body (30) disposed on the circuit substrate (10) for enclosing the LED chip (20). The light-transmitting gel body (30) has a first light-transmitting portion (30A) disposed on the circuit substrate (10) for enclosing the LED chip (20) and at least one second light-transmitting portion (30B) projected upwardly from the first light-transmitting portion (30A) and corresponding to the LED chip (20), and the second light-transmitting portion (30B) has a light output surface (300B). The light-shielding unit includes a light-shielding gel body (40) disposed on the circuit substrate (10) for exposing the light output surface (300B) of the second light-transmitting portion (30B).
