Background technology
In prior art, the packing forms of LED has several as follows conventionally:
1.Lamp-LED(vertical LED): that Lamp-LED occurs in early days is straight cutting LED, its encapsulation adopts the form of embedding.The process of embedding is first in LED shaping mold cavity, to inject liquid-state epoxy resin, then inserts the LED support that pressure welding is good, puts into baking oven and allows after epoxy resin cure, and it is moulding that LED is detached from die cavity.
2.SMD-LED(surface mount LED): paster LED is affixed on PCB surface, be applicable to SMT processing, can Reflow Soldering, lighter pcb board and reflector material have been adopted, after improvement, removed the heavier carbon steel material pin of straight cutting LED, make to show the epoxy resin that need to fill in reflector still less, object is minification, reduces weight.
3.Side-LED(side-emitting LED): another emphasis of LED encapsulation is lateral emitting encapsulation.If wanted, use LED to work as LCD(liquid crystal display) back light, the lateral emitting of LED need be identical with surface light emitting so, just can make LCD backlight luminescence even.Lumileds company utilizes the design of speculum, by the LED of surface light emitting, utilizes speculum principle to send out into sidelight.
4.TOP-LED(top light emitting LED): top light emitting LED is more common paster type light emitting type.Be mainly used in the backlight and status indicator lamp in Multifunctional ultrathin mobile phone and PDA.
5.High-Power-LED(high-capacity LED): in order to obtain the LED light source of high power, high brightness, aspect LED chip and package design to high-power future development.Such as the encapsulating structure of Norlux series high-power LED is the multi-chip combination that hexagon aluminium sheet is made base (make its non-conductive), aluminium sheet is simultaneously as heat sink.
6.Flip Chip-LED(covers brilliant LED): LED composite packing structure is to be substantially shaped with a plurality of perforation at PCB, the LED chip of a plurality of un-encapsulated is positioned over each perforation place of a side with conductive material, the positive pole of single LED chip and negative contacts be utilize tin ball respectively with substrate surface on conductive material link, and the sealing of all lighting transparent material towards the surface of a side of perforation in a plurality of LED chips, this sealing is to be a hemispheroidal shape to be positioned at each perforation place, belongs to flip-chip bonded structure light-emitting diode.
Above-described several packing forms is the packing forms of point type substantially, and its shortcoming is that light sensation is discontinuous when application, and luminous intensity distribution design is not enough, cannot multi-angle, luminous at many levels.
Summary of the invention
The technical problem to be solved in the present invention is: for the problem of above-mentioned existence, provide a kind of spirality LED encapsulation filament, make its LED can be on helicoid multi-angle, multilayer stereo luminous, more comprehensively lighting source is provided.
The technical solution used in the present invention is: spirality LED encapsulates filament; comprise substrate; it is characterized in that: described substrate is provided with the LED chip of at least one group of serial or parallel connection; substrate and LED chip surface-coated have one deck to have the dielectric layer of protection or lighting function; the electrode of LED chip is drawn by the electrode outlet line of substrate two ends, and described substrate is shaped to three-dimensional spiral shape.
Described filament substrate be conical pallidum or etc. circle helicoid.
Described LED chip is fixed on substrate with transparent adhesive tape and/or conducting resinl.
Described transparent adhesive tape and/conducting resinl is a kind of in silica gel, modified resin glue, epoxide-resin glue, elargol and sticky copper glue.
The material of described substrate is a kind of in metal, polymethyl methacrylate, plastics and the silica gel with post forming ability.
The illuminant colour of described LED chip is identical, part is identical or completely different.
The material of described dielectric layer is a kind of in the luminous arogel of silica gel, epoxide-resin glue and LED.
The electric lead-out wire at described spirality LED encapsulation filament two ends fixes on substrate two ends by glue, ceramic glue, low-melting glass, silver slurry or plastic solid, and electrode outlet line and junction, substrate two ends are provided with connecting elements.
The invention has the beneficial effects as follows: substrate of the present invention is three-dimensional spiral shape, and on this substrate, be provided with the LED chip of at least one group of serial or parallel connection, compared with prior art, overcome point type and be encapsulated in discontinuous light sensation while applying, the deficiency of luminous intensity distribution design when having overcome linear and being encapsulated in application, LED can multi-angle on helicoid, multilayer stereo is luminous.The present invention can improve the luminous intensity distribution design of light fixture in application process, can simplify technique for applying simultaneously.
