Description

Technical Field

[0001] The present invention relates to the technical field of new material detection, and in particular to a fluorescent powder detection device. Background Art

[0002] Compared to traditional light sources, light-emitting diodes (LEDs) offer advantages such as small size, energy efficiency, high luminous efficiency, long lifespan, and fast operational response. Manufacturing an LED light source typically involves mixing phosphor with glue, then applying the mixture to the chip to emit a specific color of light. The finished product is typically subject to quality inspection (factors that affect the lifespan of LEDs include: the chip's inherent light decay due to heating; the phosphor's attenuation due to heating; and the glue securing the phosphor turning yellow due to heating, absorbing some light).

[0003] At present, the existing phosphor detection device, such as the Chinese patent with publication number CN111721745B, discloses a phosphor aging detection device, which includes a blue light lamp, a metal tube, a metal cover and a photoelectric detector. The blue light lamp includes a lamp board and a plurality of blue light chips. The plurality of blue light chips are arrayed and packaged on a first surface. The first surface has a plurality of circular grooves corresponding to the outer peripheries of the plurality of blue light chips. The lower end of the metal tube is embedded in the circular groove. A glass sheet is installed inside the metal tube. The glass sheet divides the inner cavity of the metal tube into a first inner cavity and a second inner cavity arranged in an upper and lower direction along the axial direction. The first inner cavity is a plurality of grooves. The axial length of the cavity is smaller than the axial length of the second inner cavity. The metal cover is arranged above the first surface of the lamp board. The photoelectric detector includes a detector body, a detection circuit and a detection probe.
