Abstract

The invention discloses a color-temperature-adjustable COB packaging structure and a packaging method thereof. The color-temperature-adjustable COB packaging structure comprises a packaging substrate, CSP chip scale packaging devices, LED chips and a florescent glue sealing layer. The CSP chip scale packaging devices and the LED chips are fixed on the packaging substrate and wrapped by the florescent glue sealing layer. The florescent glue sealing layer is internally provided with at least one CSP chip scale packaging device and the LED chip, wherein the CSP chip scale packaging devices comprise chips and florescent glue wrapping the chips. The florescent glue and the florescent glue sealing layer are different in phosphor concentration. Light emitted by the CSP chip scale packaging devices and the LED chips passes through different numbers of phosphor powder particles and then color of different color temperature is obtained. The effect of color temperature adjustment can be achieved by controlling driving current in the CSP chip scale packaging devices and the LED chips.

Description

technical field [0001] The invention relates to an LED package structure, in particular to a COB package structure with adjustable color temperature and a package method thereof. Background technique [0002] COB light sources can be used for light source modules with small light emitting surfaces. In order to achieve adjustable color temperature of COB light sources, LED chips coated with different fluorescent materials on the surface are usually distributed in multiple different areas to achieve adjustable color temperature. [0003] It is difficult to accurately control the color temperature of the above-mentioned COB light source with adjustable color temperature, and the production process is relatively complicated; at the same time, LED chips with different color temperatures are located in different areas, and the LED chips will produce uneven light spots when they are lit, which reduces the possible The lighting effect of the LED light source with color temperature. ...
