Description
Technical field
The present invention relates to new material technology field, specially a kind of LED lampshade composite.
Background technology
For LED light source as existing most common lighting apparatus, it belongs to spot light, because spot light illumination range itself is narrow and
Dazzle can be produced, therefore existing LED typically can add lampshade, spot light is changed into area source by lampshade, its is main
Effect eliminates light scattering, and make it that LED illumination is softer, and the meeting that the material of existing LED lampshade is commonplace uses
Makrolon, and in order to assign makrolon light scattering function, often need polymer or the nothing that some are had into different refractivity
Machine particle is typed into continuous phase as dispersed phase and obtained in thermoplastic resin, and the polymer of existing addition does not often possess very well
Translucency, and substantially increase the thermal coefficient of expansion of lampshade material, have impact on LED etc. overall structure steadiness and use
Life-span.
