Embodiment 1

[0034] Soaking is to add all the raw materials in the beaker first, and then let it stand for soaking. The raw materials of different LDE light source phosphor powders may be slightly different, but the raw materials of LDE light source phosphor powders are mainly composed of phosphor powder, epoxy resin glue and some auxiliary materials. As a preference, when adding raw materials, first add 3 grams of fluorescent powder into the beaker, and then add 3 grams of epoxy resin glue; and the auxiliary materials can be added before standing and soaking. The weight of the auxiliary material is only 0.08g-0.12g; the weight of the auxiliary material added this time is 0.1g.

[0035] When the epoxy resin glue is added, the phosphor powder is flushed, and the phosphor powder is mixed with the epoxy resin glue to produce a pre-mixed effect. In order to increase the pre-mixing effect, you can add epoxy resin glue and then stir for two or three circles; and before adding epoxy resin glue, ...

Embodiment 2

[0043]Soaking is to first add 3 grams of fluorescent powder to the beaker, add 0.08 grams of auxiliary materials, and then add 3 grams of epoxy resin glue. The soaking time is 1.5 minutes. Stirring was continued in a clockwise direction for 4 minutes.

[0044] The uniformity of the fluorescent powder in the fluorescent powder is detected and the probability of directly meeting the requirements is about 65%. If the requirements are not met, continue to stir and test in turn. The stirring time in this step is 4 minutes each time; the probability of meeting the requirements is about 99% after re-testing; the phosphor powder that still does not meet the requirements is given up.

Embodiment 3

[0046] For soaking, first add 5 grams of fluorescent powder to the beaker, then add 5 grams of epoxy resin glue; finally add 0.12 grams of auxiliary materials. The soaking time is 3 minutes.

[0047] Stirring is to stir the above raw materials with glass rods to form fluorescent powder. Stirring was continued in a counterclockwise direction for 6 minutes.

[0048] The uniformity of the fluorescent powder in the fluorescent powder is detected and the probability of directly meeting the requirements is about 98%. If the requirements are not met, continue to stir and test in turn. The stirring time in this step is 4 minutes each time; the probability of meeting the requirements is about 98% in the re-test; the preparation of phosphors that still do not meet the requirements is abandoned.

Abstract

The invention discloses a method for preparing LDE light source fluorescence powder and a method for detecting a fluorescent powder uniform degree, and belongs to the technical field of electrical components. The method for preparing the LDE light source fluorescence powder and the method for detecting the fluorescent powder uniform degree solve the problems that existing LDE light source fluorescence powder is large in preparation quantity and the uniform degree is difficult to detect. The method for preparing the LDE light source fluorescence powder is composed of a soaking step, a stirring step and a detecting step. The method for detecting the fluorescent powder uniform degree is composed of a sampling and liquid dropping step and an observing and judging step. According to the method for preparing the LDE light source fluorescence powder, stirring time can be greatly shortened through preparation of a small dose of the fluorescence powder and through still standing and soaking, and workload is effectively reduced. The method for detecting the fluorescent powder uniform degree is ordinary in required equipment and low in personnel requirement. The method for detecting the fluorescent powder uniform degree further has the advantages of being convenient to control and short in time required by detection, and hardly influencing valid duration of the LDE light source fluorescence powder.

Description

technical field [0001] The invention belongs to the technical field of electrical components, and relates to an LDE light source fluorescent powder, in particular to a method for configuring the LDE light source fluorescent powder. [0002] The invention belongs to the technical field of electrical components, and relates to an LDE light source fluorescent powder, in particular to a method for detecting the uniformity of the fluorescent powder in the fluorescent powder. Background technique [0003] LED is a solid-state semiconductor device that converts electrical energy into visible light. It changes the principle of incandescent lamp tungsten filament luminescence and energy-saving lamp three-based toner luminescence, and uses electric field luminescence. According to the analysis, the characteristics of LED are very obvious, such as long life, high luminous efficiency, low radiation and low power consumption. Therefore, the LED industry is currently a sunrise industry ...
