Preferably, the toughener includes PETG, PCTG or K glue, and the partial size of the light diffusing agent is 0.6~3um.
AS toughness of material of the invention is high, shock resistance is good, breaches the functional limitation of traditional AS material, can not only
High photosynthetic efficiency is kept, injection blow moulding is applied also for, is capable of the PC material production LED lamp cover of fictitious hosts valuableness, expands AS material
In the application range of LED illumination industry, cost can reduce by 40% compared with PC material, have biggish cost advantage.
Inventor also proposed the preparation method of the AS material of above-mentioned high tenacity, the preparation method the following steps are included:
S1 weighs material composition in proportion；
The material composition claimed is put into mixing machine and mixes, obtains mixture by S2；
Mixture described in S2 is added in double screw extruder by S3, after melting, extrusion, granulation and drying process, i.e.,
?.
Inventor has found that the lampshade of traditional LED lamp, spout part abut the setting of notch due to the setting of notch, buckle,
So that the unreasonable products structure after assembly, affects the fitness and stable connection of lampshade and Lamp cup, and height is occurring
When sky falls, stress is easier to concentrate and chipping, when implementing in a manner of the lampshade manufactured by traditional AS material, the above problem
It is more prominent, therefore also proposed lampshade structurally reasonable made from a kind of AS material as above-mentioned high tenacity, the lampshade packet
Spout part is included, the outer surface of the spout part non-notch, the spout part is equipped with buckle.
Preferably, the spout part is in convex hoop shape, described to buckle the outer surface for being evenly arranged in the spout part.
When lampshade and Lamp cup of the invention is assembled together, the fitness and stable connection of lampshade and Lamp cup assembly can be enhanced
Property, when falling, the structure of spout part and buckle may also function as buffer function, and the energy moment that can avoid whole focuses on lampshade
Chipping on one point, structure is more reliable.
