PURPOSE: A natural convection heat dissipation light emitting diode lamp is provided to conspicuously improve heat dissipation performance by establishing a heat dissipation part inside a lamp internal space. CONSTITUTION: A light source part(10) comprises a PCB(13), and at least one LED(11) mounted in the PCB. A heat dissipation part(30) comprises an optical source part main chuck(31), an upward ventilation path(32), and a ventilation radiating unit(33). The optical source part main chuck and the upward ventilation path are used in order to exchange the heat of the PCB of the optical source part. The ventilation radiating unit executes the induction operation of the natural convection and a heat dissipation operation. The heat dissipation part is installed inside an optical induction diffusion body(50). A ventilation hole(53), which is formed in the upper part of the optical induction diffusion body, is connected to the ventilation path. |
