Description

High-power LED lamp based on new composite phosphor package

technical field

The utility model relates to the technical field of LED lamps, in particular to a high-power LED lamp packaged based on a novel composite phosphor.

Background technique

LED light sources have the advantages of high luminous efficiency, low heat generation, power saving and long life, and have been widely used and gradually replaced traditional lighting fixtures such as incandescent lamps and halogen lamps. However, incandescent lamps have a long history, and their appearance and luminous effects have long been deeply rooted in the hearts of the people and are highly accepted. Therefore, LED lamps that imitate the appearance and luminous effects of incandescent lamps are very popular.

Existing LED lamps are mostly integrated light source modules packaged with fluorescent powder glue. Most of the phosphor powder glue is directly attached to the surface of the integrated chipset, which has poor heat dissipation. A large amount of heat will be generated after long-term work, which will cause the aging of the phosphor powder glue and affect service life, for which we propose a high-power LED lamp based on a novel composite phosphor package.
