Description

technical field

[0001] The invention relates to a light emitting diode packaging structure. More specifically, the present invention relates to an LED packaging structure that improves phosphor distribution. Background technique

[0002] Due to the characteristics of high brightness and low power consumption of light-emitting diodes (LEDs), LEDs have rapidly replaced traditional light sources in applications such as lighting and displays. As a light source for lighting, high-brightness white light is often required. Therefore, the industry has invested a lot of effort in the research and development of white light LEDs.

[0003] At present, it is known that a high-brightness white light-emitting diode can be obtained by using phosphor powder in combination with a blue-light chip (for example: GaN). The blue light emitted by the chip will excite the phosphor to generate light of another wavelength (for example, yellow light). The desired color of white light can be obtained...
