PURPOSE: An LED type bulb having an injection molding type radiant heat hall is provided to improve heat radiation of a light bulb of a light emitting diode type by installing a plurality of heat radiation rods passing through the bottom of a heat sink. CONSTITUTION: A lamp unit(1) has an LED module mounting plate in one body. The lamp unit discharges the heat from the LED module(2). The LED module comprises a plurality of LEDs. A power supply unit(3) supplies a power source for driving the LED module. A power supply unit cover(4) comprises a base which is combined with a socket. A transmission cab(5) blocks the inflow of a foreign material. A plurality of heat radiation rods(6) are installed in an LED module mounting plate. The heat radiation rods are comprised of a carbon aluminum composite material. The bottom of the heat radiation rod penetrates the LED module mounting plate. |
