Abstract
The utility model is related to LED lamp technical field, it is big to provide a kind of light emitting angle, uniform light, shadeless single filament double helix LED bulb, and technical solution is：A kind of single filament double helix LED bulb, including lamp cap, the lampshade being fixedly connected on lamp cap, the stem that is arranged in lampshade and two draw electric wire, it is characterised in that：Further include a LED filament, which is double-spiral structure, and the both ends of LED filament are drawn electric wire with two respectively and connect.
Description
Technical field
The utility model is related to LED lamp technical fields, are a kind of double helix LED bulbs.
Background technology
LED bulb usually arranges lopping by Multi-filament around stem, such to obtain the effect of 360 degree of uniformly light-emittings
LED bulb is generally not provided with filament in stem end, this is easy for that light bulb base is caused shadow region occur, influences room lighting
Effect.
As shown in figure 4, " a kind of light bulb of Double-spiral LED encapsulation " that Chinese patent ZL201420615380.5 is provided,
Including electric connector 1A, lampshade 2A, it is equipped with radiating piece in the lampshade, charges lead-out wire 3A and the LED encapsulation of at least two spiral shape
a、b；At least two spiral shape LED encapsulation is arranged on electrification lead-out wire, and spatial relation is opposite up and down.This
The defect of class double helix light bulb is：It needs to carry out four wiring that welding can just complete LED encapsulation, in addition, light bulb base (figure
4 upper end) the LED radial directions that are encapsulated in lampshade there was only half-turn, light bulb base is not beautiful because non-uniform light has local shades
It sees, waits to improve.
Utility model content
The purpose of the utility model is to overcome the deficiency in background technology, provide that a kind of light emitting angle is big, and uniform light does not have
Hypographous single filament double helix LED bulb.
The technical solution adopted in the utility model is：
A kind of single filament double helix LED bulb, including lamp cap, the lampshade being fixedly connected on lamp cap, setting are in lampshade
Stem and two draw electric wire, it is characterised in that：Further include a LED filament, which is double-spiral structure, LED filament
Both ends draw electric wire with two respectively and connect.
Preferably, several filament supports are fixed on the stem, the fixed LED light of projecting end of filament support
Silk.
Preferably, the double-spiral structure is to wait circle double-spiral structure.
Preferably, the lampshade is T-type, one kind in BT types, TT types, ED types, G types, A types.
The beneficial effects of the utility model are as follows：The LED filament of the utility model uses double-spiral structure, light bulb base tool
There is radially arranged complete filament, not will produce shade, overall beautiful, pad is few (2), and manufacturing cost is relatively low.
Description of the drawings
Fig. 1 is the utility model main structure diagram.
Fig. 2 is the utility model left view structural representation.
Fig. 3 is the overlooking structure diagram of the utility model.
Fig. 4 is the structural schematic diagram of the light bulb of existing Double-spiral LED encapsulation.
Specific implementation mode
The utility model is described in further detail below, but the utility model is not limited to following embodiment.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of single filament double helix LED bulb provided by the utility model, including lamp cap 1,
The lampshade 2 that is fixedly connected on lamp cap, the stem 6 being arranged in lampshade and two draw electric wire 3.The lampshade be T-type, BT types,
TT types, ED types, G types, one kind in A types, filled with heat dissipation gas inside lampshade.
The utility model further includes a LED filament 4, which is double-spiral structure, and the both ends of LED filament are distinguished
Draw electric wire with two to connect, i.e., one end of LED filament with wherein one draw wire welding after, towards light bulb base (Fig. 1, Fig. 2's
Upper end) helical buckling, around behind stem lower end, LED filament is radially curved, then again towards lamp cap direction helical buckling, directly
Weld together to after drawing line contacts with another.Usually, the double-spiral structure recommends the circle double-spiral structure such as use,
And in double-spiral structure, the spacing of filament and filament is evenly arranged.
In order to enhance the stability of filament, several filament supports 5 are fixed on the stem, and (end of filament support is embedded in
Into stem), the projecting end of filament support is wound into circle outside LED filament, to the fixed LED filament, reduces it
It shakes, avoids damaging.
Listed above is only specific embodiment of the utility model.Obviously, the utility model is not limited to above example,
There can also be many variations.Those skilled in the art directly can export or associate from content disclosed by the utility model
All deformations arrived, are considered as the scope of protection of the utility model.
