Problems solved by technology

[0003] The purpose of the present invention is to find a better technology to promote the realization of formula and ultra-low color temperature of 2500K by the incorporation of yellow phosphor powder and excitation of four primary color waves, so as to overcome the high color temperature of red, green and blue primary color lamp tubes. The shortcomings of strong light, large visual distortion, and glare provide a low-cost, simple process, which can be applied on a large scale, promote the formulation of yellow phosphor with eye protection effect, and use four-primary color waves to excite super Phosphor powder composition for preparing 2500K color temperature lamp products with low color temperature

Embodiment 1

[0031] The main steps are as follows (process flow chart see figure 1 ):

[0032] ⑴Forming

[0033] Will The lead-free glass straight pipe with the pipe diameter is cut to the required length, and then bent into shape by the forming machine. The temperature of the forming machine must reach the softening temperature of the lead-free glass tube during bending, and the setting temperature of the forming machine is 850~900°C.

[0034] ⑵ washing tube

[0035] Clean the bent glass surface tube to remove the broken glass and dirt remaining during the bending process, clean it with ultrasonic machinery and boiling hot water, dry it and wait for powdering for later use.

[0036] ⑶ with 2500K fluorescent powder paste

[0037] Phosphor powder formula (the phosphor powder was purchased from Jiangmen Keheng Industrial Co., Ltd.):

[0038] Pink Y 2 o 3 : Eu 70 parts

[0039] Green powder CeMgL 11 o 19 : Tb 28 servings

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 [0001] The invention relates to a fluorescent powder composition used for an eye-protecting lamp tube and a fluorescent lamp product made by using the fluorescent powder composition, belonging to the technical field of lighting. (2) Background technology [0002] The basic principle of the current eye protection lamp is to increase the low-frequency flicker to high-frequency flicker, and the flickering speed exceeds the nerve response speed of the human eye. Therefore, people will feel more comfortable for the eyes in a short time when studying and working under this kind of light. However, when the strobe of the light is increased to tens of thousands of times per second, high-frequency electronic ballasts are prone to generate electromagnetic radiation, which is very close to the human body when used, so electromagnetic radiation may affect the human brain. Make improvements. (3) Contents of the invention [0003] The purpose of the present invention...
