Problems solved by technology

[0003] At present, there are two main methods of making yellow light: (1) Excessive inorganic phosphor is used to absorb blue light, but the price of phosphor is high, the consumption of rare earth fluorescent resources is large, and the effect of improving light efficiency is not obvious, and it is applied around the LED chip. The fluorescent powder will hinder the dissipation of heat and reduce the life of the whole lamp; (2) Eliminate blue light by using a filter layer or lampshade that can absorb the blue band. Since the blue light is simply absorbed and eliminated, the overall light effect will generally drop by 40- 50%, lower energy utilization

[0020] The preparation method of the fluorescent lampshade of an embodiment provided by the present invention comprises the following steps:

[0021] Step S110: uniformly mixing the fluorescent material and the plastic substrate to obtain a mixed material;

[0022] Step S120: Process the mixed material to obtain the fluorescent lampshade, the fluorescent lampshade has photoluminescence performance; wherein:

[0023] The fluorescent material is (denoted as fluorescent material A) or (denoted as fluorescent material B) or (denoted as fluorescent material C), the R1, R2, R3 and R4 are alkyl or aromatic groups.

[0024] In some preferred embodiments, the mass ratio of the fluorescent material to the plastic substrate is between 0.01% and 1%.

[0025] In some preferred embodiments, the transparent plastic is one of polycarbonate, polypropylene or acrylic.

[0026] In some preferred embodiments, in the step of processing the mixed material to obtain the fluorescent lampshade...

Embodiment 1

[0032] Add 0.5g of fluorescent material A to 5kg of polycarbonate plastic particles, stir and mix evenly, heat at 200 degrees for 1 hour, and obtain a fluorescent lampshade by injection molding, and then combine the fluorescent lampshade with a blue LED array to obtain the whole lamp, the entire yellow light The light effect is 122.0lm / W.

Embodiment 2

[0034] Add 20g of fluorescent material B to 5kg of polypropylene granules, stir and mix evenly, and heat at 250°C for 1 hour. The mixed material is extruded to obtain a fluorescent lampshade, and then the fluorescent lampshade is combined with a positive white LED array to obtain a whole lamp. The entire yellow light The light effect is 153.7lm / W.

Abstract

The invention provides a fluorescent lamp cover. The fluorescent lamp cover is prepared by adopting a fluorescent material with high fluorescent quantum efficiency and a plastic substrate with high stability; the fluorescent lamp cover and a blue-light or white-light LED array are assembled as the yellow fluorescent lamp; the fluorescent lamp cover can improve the energy utilization rate through further converting blue light to needed yellow light; the yellow fluorescent lamp with high light effect is finally obtained; and compared with a traditional method of directly filtering away all blue light, the yellow fluorescent lamp greatly improves the light effect, increases the energy utilization efficiency, and reduces the energy consumption.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a fluorescent lampshade, a preparation method of the fluorescent lampshade and a yellow light lamp. Background technique [0002] Yellow light, also known as anti-ultraviolet yellow safety light, adopts a unique coating, which will eliminate 500nm ultraviolet rays, hardly emit blue-violet light below 500nm, and only contain pure yellow spectrum. At present, it is mainly used in: PCB circuit board, photolithography, printing plate making, lighting room, museum, array room and other UV protection areas. [0003] At present, there are two main methods of making yellow light: (1) Excessive inorganic phosphor is used to absorb blue light, but the price of phosphor is high, the consumption of rare earth fluorescent resources is large, and the effect of improving light efficiency is not obvious, and it is applied around the LED chip. The fluorescent powder will hinder the dissipation ...
