| 摘要 |
The present invention relates to an LED lamp that has a heat dissipation structure in which bar-shaped LED tubes having heat sinks coupled thereto are coupled to respective heat dissipation fins of a central heat sink, which radially protrude from the outer peripheral surface of a hollow cylindrical body thereof, so as to be disposed in the shape of a pillar of a reel, on which a thread of a kite is wound, while forming gaps for heat dissipation therebetween at a predetermined interval, and the length of the central heat sink is restricted to be smaller than those of the LED tubes, whereby the internal space of the LED lamp is open through the gaps for heat dissipation in all directions so that a space for facilitating the convection of air is ensured to maximize the convection of air irrespective of the installation posture of the LED lamp. The present invention can maximize heat dissipation since the internal space of the LED lamp, where heat generated when the LED tubes and LEDs on a lower substrate emit light is released through the plurality of bar-shaped heat sinks, the central heat sink, and upper and lower heat sinks, is open in all directions to facilitate the convection of air. In particular, the present invention can maximize heat dissipation irrespective of the installation posture of the LED lamp through the heat dissipation structure in which the gaps for heat dissipation, formed between the LED tubes, and the internal space of the LED lamp communicate with each other. |
