Abstract

The invention provides a color-temperature-adjustable LED package device and an application method thereof, and relates to the technical field of LEDs. The device comprises a first light source, a second light source and a third light source. The first light source, the second light source and the third light source adjoin one another closely. The first light source comprises a fluorescent adhesive layer excited by a blue-ray chip, wherein the luminous power ratio of blue rays is 0.15-0.25, and the luminous power ratio of excited fluorescent powder is 1. The second light source comprises a fluorescent adhesive layer excited by a blue-ray chip, wherein the luminous power ratio of blue rays is 1, and the luminous power ratio of excited fluorescent powder is 0.45-0.5. The third light source comprises a green-ray chip and a transparent silica gel layer. The distances among the three color-temperature devices are close, so that light spots generated due to the distances among the multiple color-temperature devices are avoided, the luminous effect is improved, the color temperature adjusting range of white rays is 2700K-6500K, the color rendering index Ra is larger than or equal to 90, and the SDCM (standard deviation of color matching) is smaller than or equal to 3.

Description

technical field [0001] The invention relates to the technical field of LEDs, and in particular to an LED packaging device with adjustable color temperature and a use method thereof. Background technique [0002] Now with the development of semiconductor lighting technology, white LED light sources with adjustable color temperature have been widely used in high-quality lighting and special lighting. Commonly used color temperature adjustable technologies include: 1) Using multi-chip integrated white LEDs; 2) Using low color temperature white LEDs and high color temperature LEDs to mix light; 3) Mixing light through red, green, and blue single-color LEDs. From the perspective of technical feasibility and performance stability, the second and third, RGB technology and high and low white LED color mixing technology, are more convenient to implement and are the most practical. [0003] CN200910036845.5 proposes a method of using low color temperature LED lamps and high color tem...
