The present invention relates to a light emitting diode (LED) lamp, and more particularly to a waterproof LED lamp having a good heat dissipation effect.

In everyday life, lamps are frequently used for the purpose of seeing clearly and in detail in the dark. Most common conventional lamps include a bulb located at the base of the lamp. Electricity is supplied to the bulb through the lamp base so that the bulb can shine. Conventional lamps do not contain any heat dissipation structure. Therefore, when the lamp shines for a long time, a large amount of heat is generated and accumulated in the lamp. The accumulated heat inevitably shortens the service life of the conventional lamp. In addition, the conventional lamp does not have any waterproof structure, so that when the water splashes, the circuit is easily shorted.
