Problems solved by technology

For high-correlated color temperature light sources, the wavelength of blue light is shorter or the peak value of blue light is higher, and the radiation dose of blue light is higher, and the radiation dose of blue light is higher, especially the blue light with a peak wavelength between 435 and 440nm, which is likely to cause certain harm to human eyes. ;

Abstract

The invention discloses a liquid for absorbing blue light of an LED light source in the technical field of preparation of blue light absorbing liquids. The liquid is prepared from the following raw materials in parts by mass: 30-60 parts of matrix resin, 15-20 parts of ethoxylated bisphenol A dimethacrylate, 8-15 parts of polyethylene glycol dimethacrylate, 6-12 parts of trimethylolpropane trimethacrylate, 2-7 parts of a light stabilizer, 1-3 parts of an antioxidant, 1.5-4.5 parts of an ultraviolet light absorber and 0.5-1 part of polymethyl methacrylate. The ultraviolet-blue light absorbing material product prepared by the preparation method disclosed by the invention has a good function of absorbing ultraviolet light (300-400nm) and blue light (400-475nm). The carbon dots are simple to synthesize, the cost is low, and the product is environment-friendly. The product is stable in optical property and rich in organic groups on the surface, can be well dispersed in polymethyl methacrylate, reduces the use amount of an initiator in the polymerization reaction process of methyl methacrylate, and also can absorb blue light in a certain range.

Description

technical field [0001] The invention relates to the technical field of preparation of blue light-absorbing liquid, in particular to a preparation method of a liquid that absorbs blue light from an LED light source and a low-blue light LED lamp. Background technique [0002] A light-emitting diode (LightEmittingDiode, LED) is a solid-state semiconductor device that can directly convert electrical energy into light energy. For the white light LED light-emitting mechanism, the most common method is to use the blue light emitted by the blue chip to excite the phosphor to emit yellow-green light, which is then mixed with the remaining blue light of the chip to form white light. Such a light-emitting mechanism has many advantages such as high light efficiency and environmental protection, but it also hides safety problems, such as blue light hazards. A typical blue light chip excites phosphor powder to generate white light, and its spectrum will have a blue light peak below 500nm...
