  • Patent number: 9525113
    Abstract: A method of manufacturing a LED package structure for preventing lateral light leakage includes placing a plurality of light-emitting units on a carrier substrate, the light-emitting units being electrically connected to the carrier substrate; forming a plurality of light-transmitting gel bodies on the carrier substrate for respectively enclosing the light-emitting units, the light-transmitting gel bodies being separated from each other to form a gel receiving space among the light-transmitting gel bodies; forming a light-shielding gel body to fill up the gel receiving space; and then cutting the carrier substrate and the light-shielding gel body to form the plurality of LED package structures separated from each other, the carrier substrate being cut to form a plurality of circuit substrates for respectively carrying the light-emitting units.
    Type: Grant

  • Patent number: 9236541
    Abstract: An LED package structure for preventing lateral light leakage includes a substrate unit, a light-emitting unit, a light-transmitting unit and a light-shielding unit. The substrate unit includes a circuit substrate. The light-emitting unit includes at least one LED chip disposed on the circuit substrate and electrically connected to the circuit substrate. The light-transmitting unit includes a light-transmitting gel body disposed on the circuit substrate for enclosing the LED chip. The light-transmitting gel body has a first light-transmitting portion disposed on the circuit substrate for enclosing the LED chip and at least one second light-transmitting portion projected upwardly from the first light-transmitting portion and corresponding to the LED chip, and the second light-transmitting portion has a light output surface. The light-shielding unit includes a light-shielding gel body disposed on the circuit substrate for exposing the light output surface of the second light-transmitting portion.
