A kind of 360 degree printing opacity LED filaments

Technical field

The utility model relates to LED illumination, specifically refers to a kind of 360 degree printing opacity LED filaments.

Background technology

LED is light-emitting diode (LED, the abbreviation of Lighting emitted diode), and it is to utilize under electric field action, the bind up one's hair Sony ericsson mobile comm ab of light of PN.It has high life, environmental protection, energy-conservation feature, is the new light sources of environmental protection.Existing LED is extensively in many neighborhood application such as family, market, hotel, automobile.

Current packaging, is mainly two kinds, the one, and straight cutting LED, on metallic support, fixed L ED chip, then forms with epoxy resin encapsulated; A kind of is planar structure encapsulation, LED chip is fixed on to planar bracket or substrate, then with silica gel or resin embedding.The product lighting angle of these two kinds of structures is all less than 180 degree, and chip bottom light is all wasted, and sidepiece light also has part loss.The light utilization efficiency of above-mentioned two kinds of LED chips is quite low, particularly fails to make full use of LED chip all-round luminous.

Utility model content

The purpose of this utility model is to provide the 360 degree printing opacity LED filaments that a kind of interest rate simple in structure, easy to assembly, luminous is high, irradiation angle is wide.

To achieve these goals, the utility model is designed a kind of 360 degree printing opacity LED filaments, the transparent overcoat that comprises transparency carrier, suit substrate, the top and bottom of transparency carrier are provided with row or multiple row LED chip, in transparency carrier both sides, are provided with metal electrode, and metal electrode passes transparent overcoat, between metal electrode and transparent overcoat, be tightly connected, the top and bottom of described transparency carrier all apply phosphor powder layer, and adjacent LED chip is serially connected by gold thread, LED chip be spaced apart 0.5-4mm.

Described transparency carrier be above provided with a row LED chip, in the top and bottom of transparency carrier, all apply phosphor powder layer, adjacent LED chip is serially connected by gold thread, LED chip be spaced apart 1mm.

The top and bottom of described transparency carrier are respectively provided with a row LED chip, in the top and bottom of transparency carrier, all apply phosphor powder layer, and adjacent LED chip is serially connected by gold thread, LED chip be spaced apart 4mm.

Described transparency carrier is glass substrate or epoxy resin base plate or sapphire substrate or transparent ceramic substrate.

The thickness of described transparency carrier is less than 0.5mm.

The transparent filament encapsulation of the utility model 360 degree printing opacity LED filament LED, N low power LED chip is directly encapsulated on high temperature resistant, high-strength transparence substrate, adopts gold thread series connection conducting, and apply fluorescent material below substrate two, because substrate is very thin, it is luminous that 360 °, rear filament is lighted in energising.

Fig. 1 is the front view of the utility model 360 degree printing opacity LED filaments;

Fig. 2 is the internal structure schematic diagram of Fig. 1;

Fig. 3 is the perspective view of the utility model 360 degree printing opacity LED filaments.

Embodiment

For the ease of those skilled in the art's understanding, below in conjunction with specific embodiment and accompanying drawing, structural principle of the present utility model is described in further detail.

Described in the utility model 360 degree printing opacity LED filaments, transparency carrier 1 is glass substrate or epoxy resin base plate or sapphire substrate or transparent ceramic substrate.

Described in the utility model 360 degree printing opacity LED filaments, the thickness of transparency carrier 1 is less than 0.5mm.

The utility model 360 degree printing opacity LED filaments adopt transparent ultra-thin material substrate, this transparency carrier includes but not limited to glass, epoxy resin, sapphire, transparent ceramic etc., thickness is less than 0.5MM, direct fixed chip on transparency carrier, wire gold thread welding for chip chamber positive and negative electrode, substrate both sides external power supply both positive and negative polarity, at substrate positive and negative, all apply fluorescent material, transparency carrier surrounding is wrapped up by fluorescent material like this, blue light light that LED chip sends is comprehensive to be absorbed by fluorescent material and excites, LED light extraction efficiency is promoted greatly, and full angle is luminous, light is more soft natural, more approach incandescent lamp light, but than incandescent lamp energy-conservation 90%.

The above, be only preferred embodiment of the present utility model, not the utility model done to any pro forma restriction; The those of ordinary skill of all industry all can be implemented the utility model with the above shown in by specification accompanying drawing swimmingly; But all those skilled in the art are not departing within the scope of technical solutions of the utility model, can utilize disclosed above technology contents and a little change, the modification of making and the equivalent variations developing, be equivalent embodiment of the present utility model; Meanwhile, the change of any equivalent variations that all foundations essence technology of the present utility model is done above embodiment, modification and differentiation etc., within all still belonging to the protection range of the technical solution of the utility model.
