Abstract:
A light emitting device includes a light emitting diode chip, a heat conductive plate mounting thereon the light emitting diode chip, a sub-mount member disposed between said light emitting diode chip and said heat conductive plate, a dielectric substrate stacked on the heat conductive plate and being formed with a through-hole through which the sub-mount member is exposed, an encapsulation member for encapsulation of said light emitting diode chip, and a lens superimposed on the encapsulation member. The sub-mount member is formed around a coupling portion of the light emitting diode chip with a reflective film which reflects a light emitted from a side face of the light emitting diode chip.

Abstract:
Light emitting device 1 includes an LED chip 10, a mounting substrate 20 carrying the LED chip, a dome-shaped color conversion member 70, and encapsulation member 50. Color conversion member 70 is molded from a transparent resin material and a fluorescent material which is excited by a light emitted from the LED chip to emit a light of a color different from a luminescent color of the LED chip, and is bonded to the mounting substrate to surround LED chip 10. Encapsulation member 50 is made of an encapsulation resin material to encapsulate LED chip 10 and bonding wires 14 within a space confined between mounting board 20 and color conversion member 70. Encapsulation member 50 is of a convex-shape to have its light output surface 50b kept in an intimate contact with an internal surface of color conversion member 70. Since the intimate contact between the convex-lens shaped encapsulation member 50 and the color conversion member is made without the use of a conventional frame, the light emitting device can restrain the generation of voids in the encapsulation member, and therefore give improved reliability. Moreover, the light output efficiency is also improved.
Abstract:
A light emitting device including a thinned color conversion layer which emits a light with a minimized color ununiformity. The light emitting element includes an LED chip, a color conversion layer. The color conversion layer is made of a light-transmissive material containing a phosphor. The phosphor is excited by a light emitted from the LED chip to emit a light of a color having a wavelength longer than that of a luminescent color of the LED chip. The LED chip is provided at its top surface with a frame-shaped electrode which extends along its edge. The color conversion layer is formed on the top surface of the LED chip at an area surrounded by the frame-shaped electrode.

Abstract:
An automated part assembly machine has a work table supported to a base and movable relative thereto and at least two separate robots each having an end effector movable around within an individual work region. The two robots are positioned in such a relation as to give a common work region in which the individual work regions of the two robots overlap. A parts supply is arranged to the work table for storing parts to be picked-up by the robots. A plurality of operator hands are selectively and removably attached to the end effector of the robot for handling the parts by the robot. Disposed within the common region is a jig which positions the parts for assembly by the robot. The robots and the work table are controlled to operate in cooperation for assembly of the parts. The machine is characterized in that the robots are mounted on the movable work table together with the operator hands and the jig with the robots spaced in the moving direction of the work table, and that the parts supply extends in the moving direction of the work table. Thus, the robots are enabled to move together with the jig and the operator hands relative to the parts supply so that the robots can reach over a wide range of the parts supply beyond the individual work regions to thereby successfully pick-up suitable parts and transfer them to the jig for immediate assembly of the parts. Further, since the operator hands are on the movable work table, the robot can change the operator hands while moving relative to the parts supply for effecting the part assembly substantially without interruption, in addition to the advantage of enabling one robot to change the operator hand while the other robot is handling the parts.
