Patent ID: 8070316

Claim:
A lighting apparatus with LEDs comprising: a metal-made main body; a plurality of LED chip units each including an LED chip and a pair of lead terminals electrically connected to electrodes of said LED chip; a circuit board formed with a circuit pattern configured to supply an electric power to the individual LED chip units; and a dielectric layer disposed between said main body and said LED chip units for making electrical insulation therebetween as well as thermally coupling the same, wherein said circuit board is formed with a plurality of windows through which the individual LED chip units extend respectively with said lead terminals held in electrical contact with said circuit pattern at the periphery of said windows, each of said LED chip units being thermally coupled at its bottom face with said main body through said dielectric layer, a light-transmissive member being provided to pass a visible light from each of said LED chip units, said light-transmissive member comprising lenses at respective portions opposed to said LED chip units for determining orientation of the light given off from said LED chip units, said light-transmissive member being made of metal at a portion other than said lenses, said portion other than said lenses contacting with said main body wherein a mirror is formed on a top face of said circuit board opposed to said light-transmissive member for reflecting the visible light.
