Description

A kind of quantum dot module, light emitting module and light fixture using coating technique to encapsulate

Technical field

This utility model relates to lighting field, luminescence and the light fixture especially relating to a kind of quantum dot module with applying this quantum dot module.

Background technology

Development along with technology, technology of quantum dots is the most more and more applied to field of LED illumination, it can improve the colour gamut of display, and have luminous continuously adjustabe, launch light excitation height, conversion efficiency advantages of higher, thus has become as the core material of illumination of future generation and Display Technique.Owing to quantum dot is the most sensitive with moisture to oxygen, therefore quantum dot typically cannot directly use, but need to be packaged processing to it, in prior art, most employing silica gel are packaged, will mix with quantum dot by silica gel, utilizing silica gel to intercept the erosion to quantum dot of the water oxygen, the most this method cannot eliminate the infiltration of the little molecule such as hydrone, oxygen thoroughly, thus badly influence the service life of quantum dot.

Utility model content

In order to overcome the deficiencies in the prior art, this utility model provides a kind of quantum dot module using coating technique to encapsulate, each surface of the carrier layer being mixed with quantum dot can be covered, thus intercept the water oxygen in outside air completely, greatly improve the service life of quantum dot.

This utility model provides a kind of light emitting module.

This utility model also provides for a kind of light fixture.

This utility model solves its technical problem and be the technical scheme is that

A kind of quantum dot module using coating technique to encapsulate, including pedestal, Obstruct membrane and the carrier layer being mixed with quantum dot, the carrier layer that the upper surface of pedestal is coated with, and carrier layer not surface with base into contact is coated with completely by Obstruct membrane, wherein, the material that pedestal, Obstruct membrane are hindered oxygen with carrier layer by printing opacity and water proof is made.

As the further improved procedure of such scheme, pedestal is sapphire, quartz or glass.

As the further improved procedure of such scheme, Obstruct membrane is silicon monoxide film, silicon dioxide film, di-aluminium trioxide film or Parylene.

As the further improved procedure of such scheme, carrier layer is silica gel, PMMA, PC, PVA, EVA, epoxy resin, polyurethane, photoresist or PVP.

As the further improved procedure of such scheme, the upper surface of pedestal is etched with groove, and carrier layer is arranged on inside grooves, and Obstruct membrane coated carrier layer is exposed to side surface and the upper surface of groove.

As the further improved procedure of such scheme, Obstruct membrane by spin coating, be deposited with, sputter or Atomic layer deposition technique film forming.

A kind of light emitting module, including phosphor powder layer and above-mentioned quantum dot module, quantum dot module covers phosphor powder layer by pedestal.

A kind of light fixture, including above-mentioned light emitting module.

The beneficial effects of the utility model are:

Each surface of the carrier layer being mixed with quantum dot can be covered, thus intercept the water oxygen in outside air completely, greatly improve the service life of quantum dot.
