Abstract:
PURPOSE: A light emitting device, a manufacturing method thereof, a light emitting device module, and a manufacturing method thereof are provided to improve the adhesion of a preliminary fluorescent substance sheet by forming a first and a second bump on a light emitting device. CONSTITUTION: Light emitting devices(500) are manufactured. A preliminary fluorescent substance sheet(100') is manufactured. The preliminary fluorescent substance sheet includes mounting regions for the light emitting devices. Adhesive is applied to the preliminary fluorescent substance sheet. The light emitting devices are mounted on the mounting regions. The preliminary fluorescent substance sheet having the light emitting devices is divided into chip units.
Abstract:
A light emitting device package is provided. The light emitting device package comprises: a package substrate including a first conductive layer and a second conductive layer which are spaced apart from each other; and a light emitting element mounted on the package substrate to overlap the first conductive layer with the second conductive layer, wherein a first slit is formed in a portion of the first conductive layer which is not overlapped with the light emitting element.
Abstract:
PURPOSE: A method for manufacturing a light-emitting device is provided to omit the process for forming a wavelength converting part in each module by using a flip chip bonding method. CONSTITUTION: A bonding layer(100) is formed on a substrate(110). Light emitting devices(10) are formed on the bonding layer. A pressing member compresses the light emitting devices to form the same height. A wavelength converting part for covering the light emitting devices is formed on the bonding layer. The pressing member compresses the wavelength converters to planarize the upper surface of the wavelength converters. The bonding layer is separated from the light emitting devices.
Abstract:
PURPOSE: An apparatus for manufacturing a light emitting diode and a manufacturing method using the same are provided to control the thickness of fluorescent substance and to reduce the color deviation of the light emitting diode. CONSTITUTION: A light emitting device is installed on an adhesive film(20). The adhesive film is arranged on a lower plate mold(10). A medium plate mold(30) is arranged on the adhesive film. A separation mold is arranged in the upper or lower side of the adhesive film. A light emitting device acceptance mold is arranged to the opposite surface of the separation mold.
Abstract:
PURPOSE: A light emitting device lens, a light emitting device module including the same, and a manufacturing method of the light emitting device module using the same are provided to form a florescent substance layer and the lens in a lump by arranging the lens after dispensing the florescent substance layer. CONSTITUTION: A substrate(200) is made of metal, silicon or ceramic. A light emitting device chip(300) is mounted in a cavity(210) of the substrate. A lens is composed of an upper part(110) and a lower part(120). The lens includes a first depression part and a second depression part. A florescent substance layer is formed in the shape having the same radius of curvature as the upper part of the lens.
