Light emitting unit, apparatus and method for manufacturing the same, apparatus for molding lens thereof, and light emitting device package thereof
View Patent ↗A light emitting unit, an apparatus and method for manufacturing the same, an apparatus for molding a lens thereof, and a light emitting device package thereof, which are capable of achieving an enhancement in light extraction efficiency and an improvement in mass productivity, are disclosed. The light emitting unit manufacturing apparatus includes a mold including a first mold and a second mold coupled to each other under a condition in which at least one light emitting unit is interposed between the first and second molds, a groove formed in one of the first and second molds at a position facing the light emitting unit, the groove having a lens shape, and a passage extending from an outer surface of the mold to the groove.
1. A light emitting device package module, comprising:
a printed circuit board;
at least one package body located on the printed circuit board;
at least one lens directly molded on the package body; and
at least one board protector on the printed circuit board, the board protector being formed as a strip extending along the periphery of the lens, the strip being a circular protrusion and being coupled to the printed circuit board.
2. The light emitting device package module according to claim 1 , wherein the board protector is to protect the printed circuit board during the direct lens molding process.
3. The light emitting device package module according to claim 1 , wherein the board protector is in contact with the edge of the lens.
4. The light emitting device package module according to claim 1 , wherein the package body includes a lead printed on the printed circuit board to configure a desired circuit, and
wherein the board protector has a height larger than that of the lead.
5. The light emitting device package module according to claim 1 , wherein the board protector is made of an elastic material.
