The invention relates to a coating for improving the color rendering index of an LED lamp, wherein the raw materials and the weight percentage contents of the raw material are as follows: inorganic filler 40-50%, red fluorescent powder 0.1-1%, a coating resin 0.1-3%, cellulose nanocrystal 0.1-3%, dialkyl p-biphenol 0.1-3%, and ultraviolet absorber 40-60%. The coating for improving the color rendering index of the LED lamp is provided, as that red fluorescent powder is used for secondary excitation, so as to realize that the coating emits the red light, the color rendering index of the light source is improved, the color temperature is changed, and the color rendering index of the light source is changed by adhering the coating on the lamp shade or the panel, so that high light astigmatismand high light transmittance can be achieved simultaneously, and the color rendering index of the light source is also improved.
Description
technical field [0001] The invention relates to a coating, in particular to a coating suitable for LED lamps for improving the color rendering index of LED lamps. Background technique [0002] Rare earth phosphors are well known for general lighting fluorescent lamp applications. Rare earth phosphors contain at least one rare earth element, usually as an activator ion (eg, Eu2+, Tb3+, Ce3+). All manufacturers of such luminaires use rare earth phosphors to produce luminaires with different light output levels (lumens), color temperature (CCT) and CRI. Typical rare earth phosphors commercially used in fluorescent lamps include red-emitting Y2O3:Eu (YOE), green-emitting La(PO4):Ce,Tb (LAP), and blue-emitting BaMgAl10O17:Eu (BAM). Other green-emitting phosphors such as (Ce,Tb)MgAl11O19 (CAT) and (Gd,Ce,Tb)MgB5O10 (CBT) and blue-emitting phosphors such as Sr5(PO4)3:Cl,Eu (SCAp) are of great interest to this field. The skilled person is also well known. [0003] As a semicondu...
