A kind of filament LED, comprising: LED silk, Glass lamp column holder, insulation solidification glue-line, heat-conducting liquid or have the liquid of photoluminescence property, glass envelope, the lamp holder handware of standard and internal drive power supply; Wherein, it is inner that internal drive power supply is arranged on lamp holder handware, lamp holder handware is fixedly connected with the glass envelope of sealing, glass envelope inside arranges glass pillar, glass pillar is added is provided with LED silk, and LED silk is connected with the lead-in wire being located at glass pillar inside, and lead-in wire is connected with the terminals of internal drive power supply, the negative terminal lead-in wire connecting LED silk is also connected with lamp holder handware, the interior liquid of filling heat-conducting liquid or having photoluminescence property of glass envelope.

Described LED silk has four, and mode in parallel again of connecting between two is connected with lead-in wire after welding.

Described glass pillar be arranged in parallel two conductors, and the positive and negative terminal of LED silk head and the tail and wire is bridged on two conductors respectively.

LED silk and pin interfaces place, lead-in wire and the interface of internal drive supply terminals, lead-in wire and glass pillar interface, overall lead-in wire, the outside of conductor, and the interface of glass envelope and glass pillar all solidifies glue by insulating and seals.

Described LED silk is the fluorescent material filament prepared by 4CzTPN-Ph.

Described heat-conducting liquid is the heat-conducting liquid with photoluminescence property.

Described heat-conducting liquid is that oxolane mixing is molten.

Relatively and prior art, the utility model has the following advantages:

Add between LED silk and glass envelope in the utility model and there is heat-transferring solution, its heat dissipation problem can be solved, effectively filament can be produced heat conduction to glass envelope surface, reduce filament temperature in time and extend burn-out life.What add that the solution with photoluminescence property significantly can improve LED goes out light characteristic as brightness, luminous efficiency, colour rendering index etc.; Further economize energy, and the improvement can being carried out specific function by proportioning different solutions, can meet particular demands, for specific use, as indoor and outdoor lighting system, and military project, Aero-Space illuminator etc.; Bulb-shaped design, heat loss through convection performance can be improved, and solution specific heat capacity is larger, long-pending large with LED silk relative contact, effectively the heat that LED luminescence produces can be conducted to tube face by the heat loss through convection effect of solution, distribute heat in time in air and also effectively extend burn-out life; Heat-transferring solution or the solution with photoluminescence property have good chemical stability, do not react with filament and contact site, ensure the normal work of LED; The good fluidity of solution, more easily injects and installs in encapsulation process.

Further, add the heat-transferring solution with photoluminescence property, send high energy visible light by LED and excite solution luminous, that significantly can improve LED goes out light characteristic as brightness, luminous efficiency, colour rendering index etc.;

Further, heat-conducting liquid or there is the solution colour of liquid of photoluminescence property, kind can transform according to necessary requirement, meets the needs of various lighting condition.
