Abstract

The utility model discloses a waterproof LED lamp covered with a sealing material. A current LED lamp is undesirable in waterproof effect, and a short circuit is caused as the inlet water inside lamp is easily permeated inside from the two end surfaces or peripheral walls of a circuit board; simultaneously, water vapour is formed to affect the using effect as the inlet water inside the lamp is not easily exhausted. The utility model provides a waterproof LED lamp covered with a sealing material, which comprises a base, a hemispheric cover which is connected with the base, a circuit board which is provided with a LED lamp bulb and an electronic component, a power supply which is connected with the circuit board, and a signal wire. The waterproof LED lamp covered with the sealing material is characterized in that a small hole is arranged on a hemispheric surface of the hemispheric cover, the circuit board is arranged in a hollow cavity of the base; and the peripheral walls and upper and lower end surfaces of the circuit board are covered with insulated waterproof radiating bodies. The waterproof LED lamp covered with the sealing material uses a structure, the peripheral walls and two end surfaces of which are covered with insulated waterproof radiating bodies, so that water vapour is prevented from permeating; simultaneously, the opening on the cover can exhaust the inlet water inside the lamp to prevent generating water vapour, thus the using effect of the LED lamp is improved.
