Description

Technical Field

[0001] The utility model relates to the technical field of optoelectronic devices, in particular to a light emitting diode with a waterproof structure. Background Art

[0002] A light-emitting diode is a semiconductor device that can convert electrical energy into light energy. It is composed of a structure consisting of two semiconductor materials, one of which is an N-type semiconductor and the other is a P-type semiconductor, forming a PN junction between them. When voltage is applied across the LED, electrons are injected from the N-type semiconductor to the P-type semiconductor, and holes are injected from the P-type semiconductor to the N-type semiconductor. When these electrons and holes recombine near the PN junction, they release energy and generate photons, thereby emitting light.

[0003] The light-emitting diodes currently on the market are mainly composed of a light-emitting chip, a conductive structure, a cover plate and a base. The user connects the conductive structure to the circuit board, and then transmits electricity to the light-emitting chip through the current passed through the circuit board, so that the light-emitting chip can emit light. In order to prevent the light-emitting chip from contacting the liquid, the cover plate and the base on the market usually need to be welded to prevent the liquid from contacting the light-emitting chip. However, after the cover plate is welded to the base, the cover plate and the base will form a whole. After the light-emitting chip is overheated and damaged, the user cannot replace the light-emitting chip and can only discard the device, thereby affecting the service life of the device. In addition, because the light-emitting chip releases heat during operation, when the device encounters different environments, it will cause tiny cracks in the packaging material due to thermal expansion and contraction, allowing moisture to penetrate into the device, thereby affecting the service life of the device. For this reason, the present application provides a light-emitting diode with a waterproof structure. Utility Model Content

[0034] Working principle: During the use of the light-emitting diode with a waterproof structure, the ring plate 12, the baffle plate 13 and the guide rod 14 need to be placed in the interior of the card slot, wherein the guide rod 14 needs to be inserted into the push slot opened by the first gear 5, and the cover plate 10 can be rotated so that the cover plate 10 can rotate with the first gear 5, the buckle plate 9, the ring plate 12, the baffle plate 13 and the guide rod 14, wherein the rotation of the first gear 5 can allow the second gear 16 to rotate with the first rotating rod 15, and then the third gear 18 can drive the second rotating rod 17 to rotate, and then the movable plate 19, the support plate 20 and the heat conducting plate 21 can be moved, so that the heat conducting plate 21 can contact with the cover plate 10, and the rotation of the ring plate 12 and the baffle plate 13 can move the baffle plate 13 to a position where it cannot move upward, and then the cover plate 10 can be fixed;
