Description

Technical Field

[0001] The utility model relates to the technical field of LED packaging technology, in particular to a UV rare earth fluorescent powder precipitation detection device. Background Art

[0002] The most commonly used white light source is to use blue light chips to excite phosphors to form white light. Due to the biological hazards of blue light, which affects human physiological health, the market now uses ultraviolet chips to replace traditional blue light chips to excite phosphors to make lighting beads, which has been widely used.

[0003] For example, the patent document with application number 202121300524.4 discloses a fluorescent powder sedimentation detection device. The utility model provides a fluorescent powder sedimentation detection device, including a heating platform, a transparent container and an excitation light source. The transparent container is used to hold transparent glue with fluorescent powder particles; the transparent container is arranged on the heating platform, and the transparent glue in the transparent container is heated by the heating platform. The transparent container is provided with a vertically extending scale, and the excitation light source is arranged on the outside of the transparent container, and the light-emitting surface faces the transparent container, and is used to irradiate the fluorescent powder particles in the transparent container to excite the fluorescent powder particles to emit light. The sedimentation rate of the fluorescent powder in the transparent glue can be simply and quickly detected. The device has a simple structure and can be realized with existing laboratory instruments without additional purchase. However, when the fluorescent powder sedimentation detection device performs sedimentation detection on the fluorescent powder in the laboratory, a handheld light source is required to irradiate the fluorescent powder. The light source cannot be accurately controlled to stably irradiate, and long-term use will also cause fatigue to the user.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and a UV rare earth phosphor precipitation detection device is proposed. Utility Model Content
