摘要:
Disclosed are a light source module (100) having excellent luminous efficiency, a fabrication method therefor, and a slim backlight unit (BLU) including the same. The light source module (100) includes a light emitting diode (LED) chip (110) electrically connected to a substrate (140) through a lower surface thereof, a wavelength conversion layer (120) formed on the LED chip (110) and enclosing at least the light exit face of the LED chip (110), and a reflector (130) formed on a region of the LED chip excluding the light exit face.

Disclosed is a manufacturing method of a light emitting diode. The manufacturing method comprises the steps of preparing a substrate and mounting light emitting chips on the substrate. An intermediate plate is positioned on the substrate. The intermediate plate has through-holes for receiving the light emitting chips and grooves for connecting the through-holes to one another on its upper surface. A transfer molding process is performed with a transparent molding material by using the grooves as runners to form first molding portions filling the through-holes. Thereafter, the intermediate plate is removed, and the substrate is separated into individual light emitting diodes. Accordingly, it is possible to provide a light emitting diode in which the first molding portion formed through a transfer molding process is positioned within a region encompassed by cut surfaces of the substrate. Since the first molding portion is positioned within the region encompassed by the cut surfaces of the substrate, second molding portions can be symmetrically formed on the side surfaces of the first molding portions in various manners.

Embodiments of the invention provide a light emitting device enabling correction of color coordinates into a desired target bin, and a method of fabricating the same. The method includes forming a first resin containing phosphors inside a cavity of a package body on which a light emitting diode chip is mounted, measuring color coordinates of light emitted by combination of the light emitting diode chip and the first resin, and correcting the color coordinates by forming a second resin on the first resin, thereby improving yield of light emitting devices.

Disclosed is a light emitting diode (LED) package having an array of light emitting cells coupled in series. The LED package comprises a package body and an LED chip mounted on the package body. The LED chip has an array of light emitting cells coupled in series. Since the LED chip having the array of light emitting cells coupled in series is mounted on the LED package, it can be driven directly using an AC power source.
