Description

Technical Field

[0001] The utility model relates to the technical field of LED lamps, and more specifically, it relates to an LED lamp packaging structure. Background Art

[0002] The light-emitting diode LED (Light Emitting Diode) is a solid-state semiconductor device that can directly convert electricity into light. Understandably, the light-emitting diode uses electric field luminescence, which changes the principles of incandescent lamp tungsten filament luminescence and energy-saving lamp trichromatic phosphor luminescence. Moreover, the characteristics of the LED are very obvious, with a long lifespan, high luminous efficiency, no radiation, and low power consumption.

[0003] The existing LED light source packaging structure is complex and inconvenient to use. It adopts a structure in which phosphor is mixed with silica gel and then covered on the surface of the chip. This mixed fluorescent glue is directly in contact with the surface of the LED chip, and the heat dissipation effect is poor. Therefore, the temperature of the fluorescent glue will increase with the increase in the temperature of the chip, which will lead to the phenomenon of accelerated aging of the fluorescent glue and change in the color of the light source. At the same time, the existing packaging substrate for LED lamps has a short lifespan during use, resulting in easy damage to internal components, thus making it inconvenient for people to use.
