A kind of preparation method of anti-dazzle eye-protection lampshade, it belongs to field of material technology, and in particular to be a kind of eye-protection lampshade.The invention aims to solve existing LED light to reduce dazzle value there are energy waste using grid, and the problem of uniformity of illuminance difference.A kind of preparation method of anti-dazzle eye-protection lampshade: it uses using plastic master batch as base material, then adds anti-dazzle additive, extrusion molding after mixing obtains anti-dazzle eye-protection lampshade after sizing.Advantage: while keeping light-source brightness, being effectively reduced dazzle value, promotes uniformity of illuminance, avoids causing the discomfort of people due to excessively high, uniformity of illuminance is poor because dazzle is worth.Present invention is mainly used for prepare anti-dazzle eye-protection lampshade.
Description
Technical field
The invention belongs to field of material technology, and in particular to be a kind of eye-protection lampshade.
Background technique
After electric light invention, it experienced the light source epoch based on incandescent lamp, although the light source of incandescent lamp is closest to too
Sunlight, it is versatile, but its energy conversion efficiency is low, the service life is short；In order to solve the disadvantage that incandescent lamp, fluorescent lamp come into being,
Energy conversion efficiency is effectively raised, service life is extended, but fluorescent lamp can generate stroboscopic, there is certain shadow to human eye
It rings, and material itself not environmentally easily causes mercury pollution；LED light itself has lot of advantages, e.g., efficient, energy-saving and environmental protection,
Service life is long, but there is also many disadvantages, such as high expensive, and since LED chip integrated level is high, light source is point light source, is led
Cause LED lamp brightness excessively to concentrate, the dazzle of generation effect is increasingly stronger, ambient light illumination with spend that poor, light source is dazzling, allows use
Person does not feel good, and damages to human eye.Currently, most of producers are to solve glare problem by grid, although this scheme
Can play the role of inhibiting dazzle, but illumination sharp fall can be made, and influence ambient light illumination with degree, the conversion of energy
Low efficiency is not suitable for promoting.It discloses within 2015 a kind of LED daylight lamp cover (Authorization Notice No.: CN204629353) and proposes one kind
Multiple reflections of the light Jing Guo lampshade physical structure, interference, diffraction are to achieve the purpose that filtering noxious smooth anti-dazzle.It is this
Structure can no doubt play the role of certain eyeshield, but prepare complexity in actual application, and the limit by lampshade shape
System, narrow application range.A kind of LED anti-dazzle blackboard lights (Authorization Notice No.: CN205504707U) are disclosed within 2016, propose one
Kind light bar fixing piece, but this structure is only applicable to blackboard lights illumination, and classroom lamp is not available, and student still will receive dazzle
It influences.
Summary of the invention
The invention aims to solve existing LED light, using grid reduction dazzle value, there are energy wastes, and illumination is equal
The problem of evenness difference, and a kind of preparation method of anti-dazzle eye-protection lampshade is provided.
A kind of preparation method of anti-dazzle eye-protection lampshade, is specifically realized by the following steps: using using plastic master batch
As base material, then anti-dazzle additive is added, the additive amount of the anti-dazzle additive is 0.1%wt~5%wt, is mixed
Extrusion molding at being afterwards 150~240 DEG C in temperature, obtains anti-dazzle eye-protection lampshade after sizing；The anti-dazzle additive tolerance
400 DEG C or more of temperature.
The principle of the invention and advantage:
One, anti-dazzle eye-protection lampshade of the invention is 150 in temperature by adding anti-dazzle additive in plastic master batch
At~240 DEG C during extrusion molding, since anti-dazzle additive is resistant to 400 DEG C or more of temperature, therefore during the preparation process, prevent
Dazzle additive invariance, is even added in plastic master batch, the formation transparent solid microballoon inside anti-dazzle eye-protection lampshade；
The light that light source issues can just enter in environment after first having to the filtration by lampshade, and anti-dazzle eye-protecting lamp of the present invention
The light that light source issues repeatedly is reflected, reflected and is interfered by its anisotropic approach first by cover, secondly passes through lamp in light
When covering internal, light is irradiated to the transparent solid microballoon inside lampshade, due to anti-dazzle dosage form at transparent solid microballoon and lamp
Cover basic material refractive index is different, and refraction and reflection many times can occur when passing through two kinds of different mediums in lampshade for light,
The light entered in space can to all the winds be spread, to greatly avoid the light of single direction, and then be reduced dizzy
Light mentions the uniformity of illuminance of high ambient light, protects human eye.But extremely low, effective solution is influenced on lamps and lanterns overall brightness, illumination
The contradiction of brightness and dazzle.
Two, anti-dazzle eye-protection lampshade of the invention is limited by the physical structure that chemical method relieves lampshade, makes lampshade
Shape can have bigger freedom degree.
Three, anti-dazzle eye-protection lampshade of the invention is by the filter action and lampshade wave-like of itself to light
Refraction and interference effect have been inherently eliminated the discomfort that light direct projection human eye generates human eye, environment dazzle value are reduced, to view
Power plays a very good protection.
Four, anti-dazzle eye-protection lampshade transmitance of the invention high (lampshade light transmittance is greater than 90%), energy conversion efficiency are high
(lamps and lanterns light efficiency is greater than 90lm/W).
Five, anti-dazzle eye-protection lampshade of the invention can be applied in daily production and life, in vast
Classroom, library, hospital, office, scientific research and other needs of primary school use the place of eye for a long time under light.
