34.First encapsulated layer 35 is used to reflect the light that the LED light source 34 is sent so that all tables of the light from the encapsulated layer 35
Face is projected, so that the light source board 30 can be used as a continuous light extraction of string configuration.The substrate 32 includes metal level 321
And it is arranged on the line layer 322 on the metal level 321.These LED light sources 34 are flip LED light source, and the line layer 322 is with owning
LED light source 34 electrically connects.The light source strip 30 also includes two conducting strips 31 for being arranged on the both ends of substrate 32.These conducting strips 31
One end stretch into first encapsulated layer 35 and electrically connected with the line layer 322 by welding realization.These conducting strips 31 it is another
One end is stretched out outside first encapsulated layer 35.As a preferred embodiment, the substrate 32 can also include an insulating barrier
(not shown), the insulating barrier are arranged between the metal level 321 and the line layer 322 so as to by the metal level 321 and the circuit
Layer 322 insulate.The insulating barrier is fabricated from a flexible material.First encapsulated layer 35 is fabricated from a flexible material, first encapsulated layer 35
In be provided with the first fluorescent material (not shown), the light that first fluorescent material is sent by these LED light sources 34 excite send it is another
The light of kind wavelength.These LED light sources 34 and first encapsulated layer 35 are arranged at the front of the substrate 32, the back of the body of the substrate 32
Face is provided with the second encapsulated layer 36 (as shown in Figure 3), and the second fluorescent material (not shown), second envelope are provided with second encapsulated layer 36
The second fluorescent material in dress layer 36 is sent the light of the third wavelength by exciting for the light sent from first encapsulated layer 35.
The light of the third wavelength make it that the back side of the light source strip 30 is externally bright, so, for this
For the user of LED filament lamp 100, the front and back of the light source strip 30 is all luminous, and whole light source strip 30 is all
Bright.The technical side that LED light source and encapsulated layer are all set on the front and back in light source strip 30 is needed in compared with prior art
For case, the present invention needs only to set LED light source in the front of the light source strip 30, greatly simplifies structure.
Fig. 1 and Fig. 2 is refer to, the light source strip 30 is bent to form curvilinear structures and make it that the partial front of the substrate 32 is corresponding
The partial rear of the substrate 32 is set.This light for just alloing to project from first encapsulated layer 35 shines directly into part should
On second encapsulated layer 36, compared to reflecting the light that comes from the inwall of bulb housing 40, for second encapsulated layer 36, from this
The light intensity for the light that the direct irradiation of one encapsulated layer 35 comes is stronger, and the fluorescent material in second encapsulated layer 36 is stimulated the light sent
Can be brighter.
It refer to Fig. 1 and Fig. 2, in addition to two wires 22 and 23, one end of the two wires 22 and 23 and the lamp holder 10
Or the driving (not shown) electrical connection in lamp holder 10, the other end of the wire pass through the stem 20 and the both ends of light source strip 30
Conducting strip 31 by welding be electrically connected.The top of the stem 20 extends to form a support towards the inwall of bulb housing 40
21, the top of the support 21 is fixed with a fixed silk 24, and the fixation silk 24 electrically connects with the wire 22.The fixation silk 24
One end is electrically connected with the conducting strip 31 of the light source strip 30, and the other end of the fixation silk 24 is connected with the snapping of light source strip 30 with should
