An improved light emitting diode, comprises a frame, a chip, a wire solder, and sealing compound. The frame is integrally made of conductive metal sheet and provides two sets of connecting pins with two connecting pins for each set. A middle connection is vertically joined to two connecting pins in one set thereof and a plate connection is vertically joined to two connecting pins in the other set thereof. A recess cup is formed at the middle part of the plate connection near the middle connection. The chip is placed and located in said recess cup. The wire solder is made of conductive metal wire and an end thereof is joined to the chip and the other end thereof is joined to the middle connection. The sealing compound covers the chip, the wire solder, part of the plate connection and part of the middle connection and forms a light head on top of the chip. It is characterized in that the plate connection has a width greater than that of said connecting pins, a lower portion of the plate connection and a lower portion of the middle connection exposing outside the sealing compound for a better dissipation of heat. Furthermore, a light emitting diode with a support is provided and the support contacting with the circuit board can reach a better heat dissipation.
