摘要： A light emitting device comprises: an LED chip mounted in a recess formed in a mounting substrate; a wavelength converting member that is disposed so as to cover the recess and the edge area around the recess and that is excited by light emitted from the LED chip to emit light of a wavelength different from an excitation wavelength; and an emission control member disposed at a light output side of the wavelength converting member so as to allow emission of light coming from an area of the wavelength converting member that corresponds to the recess and to prevent emission of light coming from an area of the wavelength converting member that corresponds to the edge area around the recess. This can prevent variations in color between light emitted from the central part of the wavelength converting member and light emitted from the part of the wavelength converting member that is located on the edge area around the recess of the mounting substrate, thereby reducing unevenness of color on the irradiation surface.

摘要： A light emitting device that can provide enhanced heat radiation as well as allowing light from a light emitting diode (LED) chip to be efficiently extracted out of the device. This light emitting device includes a metal plate (11) that is made of aluminum. The metal plate (11) has a projection (11a) projecting forward. The projection (11a) has a front side provided with a housing recess (11b). An LED chip (1) is mounted on the bottom of the housing recess (11b) so that it is thermally coupled to the metal plate (11), thus allowing heat to be radiated efficiently. A printed circuit board (12), having a grass epoxy substrate to be joined to the front surface of the metal plate (11), is provided with an insertion hole (13) into which the projection (11a) is inserted. The LED chip (1) and a bonding wire (W) are encapsulated in a transparent resin seal portion (50). The side wall of the housing recess (11b) that is part of the metal plate (11) functions as a reflector for reflecting forward light emitted from the LED chip (1). Thus, light from the LED chip (1) can be extracted efficiently.

摘要： A method of efficiently manufacturing a printed wiring board is provided. In this method, a metal thin film is formed on a substrate having a projection. Then, an initial circuit pattern is formed on the substrate by patterning the metal thin film. The initial circuit pattern comprises first and second circuit patterns isolated from each other and a conductive layer formed on the projection to make a temporary electrical connection between the first and second circuit patterns. Electroplating is performed by the passage of electric current through the initial circuit pattern to form an additional metal film on the initial circuit pattern. After the electroplating, the conductive layer on the projection is removed to provide electrical insulation between the first and second circuit patterns.

摘要： An LED luminaire is formed such that a plurality of LED chips are disposed three-dimensionally on an MID (molded interconnection device) substrate in a rectangular plate shape, by mounting three LED chips on bottom face of respective dents provided lengthwise and crosswise in one surface of the MID substrate, the LED chips including at least two types mutually diffferent in luminous color, desirably three types of red, blue and green colors. Any optional light distribution characteristic is made thereby easily obtainable depending on a configuration of the substrate, luminaire module can be thinned, and such delicate color difference as white color and day-light color of luminescent lamps is enabled by mixing the luminous colors of the respective LED chips.

A first RF power supply configured to apply a first RF power having a relatively higher frequency is connected to the upper electrode. A second RF power supply configured to apply a second RF power having a relatively lower frequency is connected to the lower electrode. A variable DC power supply is connected to the upper electrode. A process gas is supplied into the process chamber while any one of application voltage, application current, and application power from the variable DC power supply to the upper electrode is controlled, to generate plasma of the process gas so as to perform plasma etching.
