Description

Technical Field

[0001] The utility model belongs to the technical field of LED lamp beads, and more specifically, particularly relates to a protective LED lamp bead. Background Art

[0002] The LED lamp is an electroluminescent semiconductor material chip, which is cured to the bracket with silver glue or white glue, and then connected to the chip and circuit board with silver wire or gold wire. It is sealed with epoxy resin on all sides to protect the internal core wire. Finally, the outer shell is installed. The LED lamp beads are installed inside the LED lamp to provide lighting.

[0003] The existing Chinese patent announcement number is CN218001206U, which discloses a protective LED lamp bead, including a protective cover, a mounting ring is fixedly installed at the lower end of the protective cover, a heat dissipation mechanism is fixedly installed between the protective cover and the mounting ring, an LED lamp bead body and a mounting mechanism are clamped on the heat dissipation mechanism, the mounting mechanism is located above the LED lamp bead body, a plurality of heat dissipation grooves distributed at intervals are arranged on the peripheral side surface of the mounting ring, a groove is opened on the inner wall surface of the mounting ring, and the groove is connected to the heat dissipation groove. The protective LED lamp bead described in the utility model can be quickly installed by rotating the mounting plate by setting a heat dissipation mechanism and a mounting mechanism, and a No. 1 heat dissipation hole, a No. 2 heat dissipation hole, a groove and a heat dissipation groove are arranged to achieve heat dissipation of the LED lamp bead body, which reduces the influence of the protective cover on the heat dissipation of the LED lamp bead body, increases the service life of the LED lamp bead body, and is more practical. When the above-mentioned protective LED lamp beads are actually used, a transparent cover is used to protect the LED lamp beads, but the heat dissipation of the protective cover is poor during protection. Only the No. 1 heat dissipation hole and the No. 2 heat dissipation hole are used for heat dissipation, and the heat dissipation effect is not good. When the heat dissipation of the LED lamp beads is poor, its service life is easily shortened, which is inconvenient for users to use.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a protective LED lamp bead is provided to achieve a more practical purpose. Utility Model Content

The heat on the surface of the lamp bead seat will be transferred to the heat dissipation resin block and the aluminum box at the same time. The heat dissipation resin block performs preliminary heat dissipation and transfers the heat to the annular heat-conducting copper sheet and a plurality of heat dissipation fins. The annular heat-conducting copper sheet and the plurality of heat dissipation fins are used to quickly dissipate the heat again, which is convenient for cooling.

Heat is dissipated in different directions, thereby accelerating the heat dissipation efficiency, greatly improving the service life of the LED lamp bead, avoiding the situation of poor heat dissipation when protecting the LED lamp bead body, and facilitating the use of the user.

[0015] By setting an annular sealing seat, a sealing ring, an annular groove, screws, threaded holes and a heat sink for use together, the sealing ring is used to seal the aluminum box and the annular sealing seat, thereby preventing the LED lamp beads from being short-circuited when exposed to water. The sealing ring is made of heat-conducting rubber material, which improves the heat dissipation of the LED lamp beads. The heat sink further dissipates heat, so that the heat emitted by the LED lamp beads can be quickly conducted to the air, thereby protecting the LED lamp beads and preventing the LED lamp beads from being overloaded, thereby enhancing the practicality of the LED lamp beads.
