Description

Technical Field

[0001] The utility model relates to the technical field of LED bulbs, in particular to a light emitting diode bulb structure. Background Art

[0002] Light-emitting diodes, abbreviated as LEDs, are electronic devices that can convert electrical energy into light energy and are widely used in lighting, display and other fields.

[0003] The basic working principle of a light-emitting diode is to emit light through the release of energy through the recombination of electrons and holes. Its structure includes a P layer formed by a P-type semiconductor, an N layer formed by an N-type semiconductor, and an active layer in the middle composed of a double heterostructure. This active layer is the light-emitting area and is usually between 0.1 and 0.2 microns thick.

[0004] Existing light-emitting diodes are widely used, including light-emitting diode bulbs. The bulb cover of traditional light-emitting diode bulbs is set outside the LED wick. After long-term use, the substrate of the LED wick will generate a lot of heat. Due to the sealing effect of the bulb cover, the heat cannot be dissipated in time, which can easily cause the bulb core structure to overheat and be damaged, shortening the service life.
