Description

A kind of LED fluorescent eye-protecting lamp processing method of lampshade material

Technical field

The present invention relates to a kind of manufacture method of lampshade of fluorescent lamp, particularly a kind of LED fluorescent eye-protecting lamp processing method of lampshade material.

Background technology

Since China's reform and opening-up, national economy obtains rapid growth, becomes the main flow of China's industrial development with " scientific and technical innovation, autonomous innovation ".The industry of China is just step by step to the future development of saving type, energy-saving and emission-reduction, low-carbon (LC).With reference to domestic several generations light fixture, the incandescent light of the first-generation, the luminescent lamp of the s-generation, the electricity-saving lamp of the third generation etc., along with the development of new and high technology, semiconductor lighting (LED) is causing a revolution of world's lighting source.That the LED fluorescent lamp be take is of fine quality, long durable, energy-conserving and environment-protective of life-span are principal feature, and the crevice projection angle regulation range is large, and the brightness of 15W is equivalent to common 40W fluorescent lamp, high temperature resistance, and moistureproof and waterproof, anticreep, the advantage such as microminiaturized.On market, LED fluorescent lamp shade colour rendering index is less than 70% mostly now, and the transparent efficiency of LED fluorescent lamp shade is low simultaneously, printing opacity is inhomogeneous etc., makes eyes easily produce the generation of slight fatigue or eye illness.The lampshade material that must improve LED is only unique approach.From the angle of eyeshield, the colour rendering index of light is higher, and light is softer, and people's eyes are more comfortable.For addressing this problem, R&D institution and enterprise technology personnel constantly study, explore, and utilize modern science and technology, although obtained technically some progress, still exist the technical barrier not yet overcome in practice.

Summary of the invention

The object of the invention is to overcome above deficiency, a kind of LED eyeshield fluorescent eye-protecting lamp cover material production and processing method is provided.Adopt PC plastic pellet, light diffusing agent, tea green master batch, transparent glass fiber, silica gel and the fluorescent material main raw material(s) as the fluorescent eye-protecting lamp cover, adopt modern science and technology preparation and working method, make Novel LED fluorescent lamp eye-protection lampshade material.This LED fluorescent eye-protecting lamp cover has good temperature tolerance, solvent resistance, resistance to acids and bases, physical strength and surface hardness preferably.Waste is recyclable simultaneously, does not produce any pollution, is a kind of typical environmental protection light source.This light is soft, pre-myopia prevention, and long service life, good insulation preformance, non-contact electric hidden danger, easy for installation, handsome in appearance generous.

The technical solution adopted for the present invention to solve the technical problems: the main component batching is: PC plastic pellet, light diffusing agent, tea green master batch, transparent glass fiber, silica gel, fluorescent material, the proportioning of each raw material is: PC plastic pellet 85%-90%, tea green master batch 3%-5%, transparent glass fiber 4%-6%, silica gel 0.5%-0.8%, fluorescent material 0.4%-0.7%, light diffusing agent 0.4%-0.6%;

The technological process of production: PC plastic pellet → light diffusing agent → tea green master batch → transparent glass fiber → silica gel → fluorescent material → mix and blend → twin-screw extruder → die forming → product is cooling → detect → warehouse-in;

Working method is: first clean stirrer, with special tool, by the impurity of stirrer the inside, remove clean, by the PC plastic pellet, light diffusing agent, the tea green master batch, transparent glass fiber, silica gel, fluorescent material is weighing and burden proportionally, put in stirrer, then in stirrer, stirred, the material stirred is relayed in the twin-screw extruder opening for feed again, twin-screw extruder is heated, make PC plastic pellet and tea green master batch, silica gel melts, twin-screw extruder is started working, by the material extruding that melts in mould, become the semicircle moulding lampshade of rectangular parallelepiped through die drawn again, by the finished product of producing, undertaken cooling, whether even to transmittance and the colour rendering index of LED eye-protection lampshade by detecting instrument, product is after the assay was approved packed, warehouse-in, and avoid the direct irradiation of sunlight, maintain and get final product in 2～3 days.

The know-why that the present invention adopts: the LED eye-protection lampshade adopts selected PC plastic pellet, light diffusing agent, tea green master batch, transparent glass fiber, silica gel, phosphor material powder, stirs through stirrer, then forms through twin-screw extruder, Mould Machining.That utilizes fluorescent material has solvent resistance, resistance to acids and bases, a performance that transmittance is high.PC plastic pellet and transparent glass fiber have consistency, brightness is high, transmittance is high, the performance that tensile strength is good; Make that the eye-protection lampshade blushing produced is little, brightness is high, light transmission efficiency is greater than more than 85%.Silica gel has good intensity and flexibility, and acid, alkaline matter are had to high-strength corrosion resistance; The light that the LED eye-protection lampshade is sent is very soft, and it is very comfortable that eyes are felt.Utilize light diffusing agent, there is trickle and uniform size distribution, easily disperse, surface hardness preferably.The tea green master batch mixes with above-mentioned materials, and creation lampshade out is with micro-green luminosity, and mildness is better, and eye eyesight is had to certain protective role.Utilize modern science and technology, the LED eye-protection lampshade has really been realized breaking through again on the illumination history; For a large amount of medical expense that China saves, the LED eye-protection lampshade light of environmental protection is soft, gives the people visually refrigerant impression, reaches the effect of environmental protection.

The invention has the beneficial effects as follows: this LED lampshade is applied to the public places such as school, hospital, family, hotel, market, office building.LED eye-protection lampshade material is carried out to the science preparation, adopt advanced working method, the light that makes the LED lampshade send is soft, eyes sensitization is comfortable, has reached the purpose of eyeshield, vision protection.LED fluorescent eye-protecting lamp cover has reduced vaporized mercury in traditional fluorescent lamp in atmosphere, and environment is played a very good protection.This LED fluorescent eye-protecting lamp cover is succeeded in developing, and to the Economy type medicine expense, vision protection plays good effect.For China creates saving type, low-carbon (LC) society has made contribution.
