Problems solved by technology

[0005] Since the known light emitting diode packaging structure 10 needs to form the cup-shaped base 12 first, complete the packaging by molding or potting, and then integrate the individual light emitting diode packaging structures 10 on the printed circuit board 24 by surface mounting technology, the process is complicated. Difficult to mass produce

When applied to a high-power light-emitting diode packaging structure 10, the cup-shaped substrate 12 used to carry the photoelectric element 16 will affect the wavelength of the emitted light source, brightness attenuation, and even cause problems such as element burnout due to overheating.

Due to the bulky volume of the known LED packaging structure 10 and the heat dissipation requirements of the high-power LED packaging structure 10, the size and heat dissipation efficiency of the entire LED packaging structure 10 are limited.
