PURPOSE:To obtain a blue color LED device which can accommodate a smaller size LED chip by a method wherein the LED chip is attached to one of lead frames with both electrode members and an insulating spacer therebetween. CONSTITUTION:A blue color LED device has a lead frame 32 in addition to a lead frame 28 having a cup part 30. Metal electrode layers 16 and 18 which are formed on an insulating spacer 24 facing the compound semiconductor layer of an LED chip 2 are electrically connected to the lead frames 28 and 32 with conductors 34 and 36. A molding 38 which covers both lead frames 28 and 32 is formed into a lens shape so as to collect lights and so as to have the LED chip 2 which is attached to the bottom of the cup part 30 of the lead frame 28 as its center. Therefore, the LED chip can be attached to one lead frame. With this constitution, the size of the LED chip can be reduced and the size of the whole blue color LED device can be reduced. |
