  • Patent number: 9261246
    Abstract: Provided is a light-emitting module, a light source device and a liquid crystal display device in which unevenness in the luminance and color hardly occurs as compared to conventional technology. A light-emitting module 100 is structured such that a plurality of element columns, each composed of light-emitting elements 120 arranged in line, are mounted on a substrate 110, and each element column is individually sealed by a separate sealing member 130. The light source device and the liquid crystal device each include the above light-emitting module 100.

  • Patent number: 7992516
    Abstract: A phosphor layer forming apparatus (1) in which a paste (21) containing a phosphor is discharged so as to cover each of a plurality of light-emitting elements (11) mounted on a substrate (10) includes the following: a discharge portion (12) for discharging the paste (21) in the form of droplets onto each of the light-emitting elements (11); a measurement portion (13) for measuring the thickness of individual phosphor layers that are formed of the paste (21) covering each of the light-emitting elements (11); and a discharge control portion (14) for controlling the amount of the paste (21) to be redischarged for each phosphor layer in accordance with the thickness of the individual phosphor layers measured by the measurement portion (13). This phosphor layer forming apparatus can reduce the manufacturing time.

  • Patent number: 7902568
    Abstract: A light-emitting module (2) includes a mounting board (1) with a conductor pattern and a plurality of light-emitting elements (15) mounted on the conductor pattern via wires (21). The extending direction of each of the wires (21) toward the conductor pattern is oriented irregularly when viewed perpendicularly to the mounting board (1). This can prevent the shadows of the wires (21) from overlapping, and thus can suppress the luminance nonuniformity.

  • Patent number: 7861908
    Abstract: A component mounting apparatus includes a component feeder that feeds a component with its bump electrodes facing down, a mounting head that mounts the component onto a substrate, a supporting base that secures the substrate, and a positioning device that aligns the component with the substrate. The mounting head includes an ultrasonic vibration generator, an ultrasonic vibration propagation member that conveys the ultrasonic vibration provided by the ultrasonic vibration generator to a working face holding the component as vibration parallel thereto, a pressure loader that applies a pressure load to the working face from a position immediately thereabove in the direction perpendicular thereto, and a heater that heats the vicinity of the working face. Thereby, ultrasonic bonding is carried out with high reliability even if the component has a number of bump electrodes on its face.

  • Publication number: 20100309646
    Abstract: A light-emitting device (1) includes a base (10), a light reflecting member (11) placed on the base (10), a case (12) surrounding the light reflecting member (11), and a plurality of light-emitting elements (13) arranged on the inner surface of the case (12). The light reflecting member (11) reflects light emitted from an emission source including the light-emitting elements (13) toward an opening (12a) of the case (12). In the light-emitting device (1), since a plurality of light-emitting elements (13) can be arranged three-dimensionally, the size of the light-emitting device can be reduced easily. Moreover, the light reflecting member (11) reflects light emitted from the emission source including the light-emitting elements (13) toward the opening (12a) of the case (12), so that the light-emitting device can have high brightness.

  • Patent number: 7748112
    Abstract: A component mounting apparatus has a stage 41 with a fixed height position for holding a substrate 5, and a mounting head 48 that releasably holds a component 2, is moved downward toward the stage 41 from a first reference height position HB1 fixedly positioned above the stage 41, and mounts the held component 2 on the substrate 5 or an already mounted component 2. A controller 14 has a mounting reference height calculation unit 103 for calculating a mounting reference height Hn corresponding to a distance from the first reference height position HB1, and a first target movement height calculation unit 104 for calculating a first target movement height ZTAGn based on at least the mounting reference height Hn and a thickness PTn of the component 2 held by the mounting head 48.

  • Publication number: 20100064510
    Abstract: A suction nozzle (65) of a reversing head device (22) has a distal end surface (65a) with a suction hole (65b) opened therein, and a suction passage (65c) communicated with the suction hole (65b) at one end thereof. A portion of the distal end surface (65a) outside of the suction hole (65b) abuts against bumps (39) of an electronic component (12). The suction hole (65b) is opposed with a gap to a portion of a mounting side surface (12a) where no bumps (39) are present. A vacuum pump (65) creates an air flow that flows from the gap between the suction hole (65b) and the mounting side surface (12a) into the suction passage (65c) through the suction hole (65b). The electronic component (12) is held at the distal end surface (65a) by a negative pressure generated by the air flow.
