LED lighting lamp modified type component type light source structure

The utility model relates to an improved component-type light source structure for an LED lamp, comprising a light-emitting diode (LED), at least one circuit substrate and a heat dissipating base. The LED is arranged on the circuit substrate; the circuit substrate is arranged on a platform at the top of the heat dissipating base and is in circuit connection; a plurality of heat dissipating fins or teeth in conjunction with the base into a whole are arranged along the vertical direction of the base surface at the heat dissipating base; a plurality of permeable through holes or slots are respectively and correspondingly arranged at the circuit substrate and the heat dissipating base. For the light source structure, the permeable slots on the circuit substrate and the heat dissipating base ensure that the two sides of the LED, the light-emitting surface and the back light surface are fully permeable; therefore, heat can not only be dissipated through the conductive ways of the heat dissipating base and the heat dissipating fins, but can also be very fast emitted into the space outside the lamp through the convective way of the transparent structure, thus, the thermal performance of LED lamps is improved and the service life is prolonged.
