Abstract
The invention discloses a manufacturing technique of LED with optical scattered medium, which is charactered in that: plastic parts of the needed geometric shape are formed by another injection molding, on basis of the existing LED that has been encapsulated by the epoxy resin; the LED that has been encapsulated by the epoxy resin is embeded into the plastic parts of the needed geometric shape by an embeding shaping method. Its beneficial effect is that: it has a novel unique structure, an ingenious reasonable design; it is convenient for a pipelining automatic production; it may send a lamplight of peculiar pattern, and it has more decoration and display effect, and extensive application.
Description
Technical field:
The present invention relates to optics, demonstration, decoration and lighting technology, is a kind of demonstration, decoration or illuminating lamp, specifically, is a kind of LED and production technology thereof that has optical refraction and dispersion media.
The application of LED is very extensive, especially showing and the decoration field, is very popular luminescent device, as is made into Christmans light string etc.Existing LED normally puts into the LED finished product in the plastics cover, and the profile of plastics cover is coarse, and is careless about optic structure, just can satisfy basic luminous requirement.And take very much artificial and cost high.
The purpose of this invention is to provide a kind of easy to make, novel structure, can send the light of special pattern, have more and decorate and the LED that has optical refraction and dispersion media and the production technology thereof of display effect.
Technical solution of the present invention is: a kind of production technology that has the LED of optical refraction and dispersion media, it is characterized in that: on the existing LED basis good with epoxy encapsulation, form the working of plastics of the geometry that needs in addition with mold injection, will implant in the working of plastics of geometry with implanting forming process with the good LED of epoxy encapsulation.
Have optical refraction and dispersion media on the working of plastics of the geometry described in the present invention.The profile of the working of plastics of geometry is: taper, sphere, polygon, or have the geometry of optical refraction and dispersion prism structure.The interior LED of working of plastics that is wrapped in the geometry profile is single monochromatic LED or 2,3 monochromes or multi-colored led more than 3.
Beneficial effect of the present invention is: novel structure uniqueness, design be ingenious rationally, be convenient to the streamline automated production, can send the light of special pattern, has more and decorate and display effect, is widely used.
The present invention is described in further detail below in conjunction with drawings and Examples:
Description of drawings:
Fig. 1 is a kind of structural representation that has the LED of optical refraction and dispersion media of the present invention;
Fig. 2 is the production technology schematic diagram that has the LED of optical refraction and dispersion media of the present invention.
Embodiment:
Fig. 1 has described one embodiment of the present of invention, in this embodiment, existing LED1 through epoxy encapsulation is arranged, and is wrapped with the working of plastics 2 of geometry, the profile circle of the working of plastics 2 of geometry, polygon etc. at LED1.There is the optical refraction and dispersion prism structure on the surface of the working of plastics 2 of geometry.The working of plastics 2 interior LED1 that are wrapped in geometry adopt the combination (or the monochrome of other quantity or polychrome) of 1～3 monochrome or multi-colored led formation.
Fig. 2 has described the production technology that has the LED of optical refraction and dispersion media of the present invention.Wherein: 11 is existing LED, and 12 is working of plastics, and 13 is mould.Its process is: on the existing LED basis good with epoxy encapsulation, form the working of plastics of the geometry that needs in addition with mold injection, will implant in the working of plastics of geometry with implanting forming process with the good LED of epoxy encapsulation.Have optical refraction and dispersion media on the working of plastics of geometry.The profile of the working of plastics of geometry is: polygonal pyramid shape, sphere, polygon, or have the geometry of optical refraction and dispersion prism structure.The interior LED of working of plastics that is wrapped in the geometry profile is single monochromatic LED or 2,3 monochromes or multi-colored led more than 3.
Adopt and implant (INSERT/MOLDING) technology of shaping, utilize existing traditional LED to implant in batch and be injection molded into required form, purpose is to increase special optical refraction and dispersion, form pattern, can be used for decorative lamp, Christmas lamp etc., production capacity can be increased substantially, more material cost can be saved.
Directly the plastics of injection moulding can be the various plastics of PS/PC or the like outside LED.If dichromatism LED can be that two pin also can be three pin, can only dividing of two pin turned on, three pin can two kinds looks simultaneously bright.The adorning three kinds of LED and can send out combined color a lot of of four pin, four pin can be also can be two-layer on same plane.Can be with in a plurality of LED implanted same working of plasticss of while.
The working of plastics of the geometry of the present invention outside LED, material can be plastics such as PS/PC.When working of plastics was shaped, it was exactly a lot of that a secondary mould one comes out, and improves production capacity efficient.
