PROBLEM TO BE SOLVED: To prevent the heat generation of an LED and materialize high- brightness light emission by radiating heat, even in case that a large current is let flow to an LED. SOLUTION: This LED is provided with a pair of opposed top electrodes 2 at the top ends of an insulating substrate 1, and for the pair of the top electrodes 2, a bottom electrode 3 at the rear and a side electrode 4 leading to the top electrode 2 and the bottom electrode 3 at the side are made each. In the region which includes the die bond area 9 and its periphery on one top electrode 2a, a heat radiating plate 10 consisting of conductive member is fixed by a fixing means such as a conductive adhesive 11 or the like, an LED element 5 is mounted on the heat radiating plate 10, and a bonding wire 6 is connected to the other top electrode 2b sealed with sealing resin 7. Since it radiates heat even if a large current (about 300 mA or over) is let flow, it prevents the heat generation of the LED, and high-brightness light emission can be materialized. The high-brightness LED becomes inexpensive, and this can be mounted on a high-brightness target product which is not used up to now. |
