Abstract
The invention provides a phosphor composition for eye-protection lamp tubes and a finished fluorescent lamp tube made with the phosphor composition. The phosphor composition comprises, by weight, 65-70 parts of red phosphor Y2O3:Eu, 16-28 parts of green phosphor CeMgL11O19:Tb, 2-5 parts of twin-peak blue phosphor BaMgA10O17:(Eu and Mn), and 4-10 parts of yellow phosphor Y3AI2O12. The phosphor composition has four primary colors as compared with common phosphor having three primary colors and has light more approximate to sunlight. The light emitted by the phosphor composition feels warm and comfortable uniquely, color deviation of an object being watched can be improved greatly, and the color of the object is soft and nonirritating without distortion in the light. Eye fatigue in watching the object can be reduced greatly, and eyes are protected.
Description
(1) technical field
The present invention relates to a kind of phosphor combination thing that is used for the eyeshield fluorescent tube, and utilize its fluorescent tube bulb goods that make, belong to lighting technical field.
(2) background technology
The basic of current eye-protecting lamp is increased to high stroboscopic to low stroboscopic exactly, and the speed of flicker has surpassed the nerves reaction speed of human eye, therefore study under this light, office, and people can think that eyes are more comfortable in the short period of time.But with p.s. light stroboscopic bring up to up to ten thousand time after, high-frequency electronic ballast is easy to produce electromagnetic radiation, and is very near apart from human body during use, so electromagnetic radiation may impact human brain, do not improve from root.
(3) summary of the invention
The objective of the invention is in order to seek the realization that a kind of better technology promotes yellow fluorescent powder to mix to fill a prescription to inspire with four primary colours ripples ultralow colour temperature 2500K colour temperature; Overcome that three kinds of primary colours fluorescent tubes of red, green, blue colour temperature is high, light strong, look big, the dazzling shortcoming of thing distortion, provide that a kind of cost is low, technology simple, yellow fluorescent powder that can use on a large scale, that promote to have eyeshield effectiveness mixes and fill a prescription and utilize four primary colours ripples to inspire the phosphor combination thing of ultralow colour temperature with preparation 2500K color temperature lamp tubing products.
