A lighting apparatus with LED includes a metal-made main body; a plurality of LED chip unitseach including an LED chip and a pair of lead terminalselectrically connected to electrodes of the LED chip; and a dielectric layerdisposed between the main bodyand each LED chip unitfor making electrical insulation therebetween as well as bond the same. The circuit boardis formed with a plurality of windowsthrough which the individual LED chip unitsextend respectively with the lead terminals held in electrical contact with the circuit pattern of the circuit board at the circumference of the window, each of the LED chip units being thermally coupled at its bottom face with the main bodythrough the dielectric layer, and the heat generated in the LED chip is conducted to the main body through the dielectric layer without passing through the circuit board.

Lighting apparatus with LEDs

A light-emitting device of the present invention includes: a LED chip; a chip mounting memberhaving a conductive plate (heat transfer plate)one surface side of which the LED chipis mounted on and a conductor patternswhich is formed on the one surface side of the conductive platethrough an insulating partand electrically connected to the LED chip; and a sheet-shaped connecting memberdisposed on the other surface side of the conductive plateto connect the conductive plateto a body of the luminairewhich is a metal member for holding the chip mounting member. The connecting memberis made of a resin sheet which includes a filler and whose viscosity is reduced by heating, and the connecting memberhas an electrical insulating property and thermally connects the conductive plateand the bodyof the luminaire to each other.

Light-emitting device

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.
