Abstract: A lighting apparatus with LED includes a metal-made main body 90; a plurality of LED chip units 1 each including an LED chip and a pair of lead terminals 42, 43 electrically connected to electrodes of the LED chip; and a dielectric layer 80 disposed between the main body 90 and each LED chip unit 1 for making electrical insulation therebetween as well as bond the same. The circuit board 20 is formed with a plurality of windows 23 through which the individual LED chip units 1 extend 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 body 90 through the dielectric layer 80, and the heat generated in the LED chip is conducted to the main body through the dielectric layer without passing through the circuit board.
