Description

Technical Field

[0001] The utility model relates to the technical field of LED lamp beads, in particular to an LED lamp bead for a classroom lamp. Background Art

[0002] LED lamp beads are light-emitting diodes, which are commonly used light-emitting devices. They emit light by releasing energy through the recombination of electrons and holes. LED lamp beads can efficiently convert electrical energy into light energy and have a wide range of uses in modern society, such as lighting, flat-panel displays, medical devices, etc. In actual use, they have the advantages of simple operation, stable structure, long service life and good use effect. In the classroom, LED lamps are also an indispensable type of equipment, and the role of the lamp beads is self-evident. It is the "heart" of the lamp. Therefore, we have launched a classroom lamp LED lamp bead.

[0003] The existing patent (publication number: CN209249476U) discloses an LED lamp bead, including a packaging base, a light-transmitting cover, two pins and a light-emitting chip; the light-transmitting cover is covered on the packaging base to form a sealed cavity; the pin includes a contact portion, a spiral portion and a welding portion arranged in sequence, two of the contact portions are arranged inside the cavity, the two spiral portions are rotated and penetrated inside the packaging base, and do not contact each other, and the two welding portions extend out of the packaging base; the two ends of the light-emitting chip are respectively connected to the contact portion. The utility model provides a waterproof LED lamp bead, which is easy to install. The existing technology has the following problems: 1. Most of the existing LED lamp beads are in a closed state, which is easy to generate high temperature and difficult to dissipate heat during use, resulting in a shortened service life of the lamp bead; 2. The existing LED lamp bead pins are mostly connected by spot welding. When the lamp bead is damaged and needs to be disassembled, the solder needs to be melted before it can be removed, or it can be removed by force, but violent disassembly is easy to damage the light strip, which is not convenient for the later maintenance and repair of the LED lamp.
