Luminescence unit 400 is multiple.Multiple luminescence units 400 distribute and are connected in series along substrate 100 bearing of trends.Multiple luminescence units 400 are lined up at least one row and are arranged on the middle part of substrate 100 along the direction of substrate 100 extended lines.According to actual conditions, luminescence unit 400 can be lined up two row, and to be arranged on substrate 100 first-class.
See also Fig. 2 and Fig. 3, it is respectively the profile of the filament of LED shown in Fig. 1 10 and the profile of another embodiment LED filament 20.
When substrate 100 is made for light tight material, the surface coverage that substrate 100 is provided with luminescence unit 400 has fluorescent glue 500.When substrate 100 is made for light-transmitting materials, the luminescence unit 400 on substrate 100 and substrate 100 is wrapped in fluorescent glue 500.According to actual conditions, in the time that substrate 100 is light-transmitting materials, the surface coverage that also can substrate 100 be provided with luminescence unit 400 has fluorescent glue 500.
Can destroy or force to yield wire 200 and pin 300 is all attached on substrate 100.According to actual conditions, pin 300 can be and can destroy or force to yield, and also can be the metal material that can not destroy or force to yield and makes.Can destroy or force to yield wire 200 and pin 300 can be pasted on substrate 100 by materials such as plastics, adhesive glue, elargol, high-temp glue, scolding tin, metals.
See also Fig. 4, it is the structural representation of the LED bulb 30 of the LED filament 10 shown in application drawing 1.
LED bulb 30, comprise: cell-shell 700, be formed on cell-shell 700 inner leg 630, the lamp holder 600 that is connected with cell-shell 700, be arranged on driver 620, LED filament 10 in lamp holder 600, and one end is connected with driver 620 through stem stem 630, the connecting line 640 that the other end is connected with the pin 300 of LED filament 10.LED filament 10 is contained in cell-shell 700.
In cell-shell 700, be filled with protective gas.
Two substrates 100 adjacent in LED filament 10 are at an angle to each other, and the wire 200 of can destroying or force to yield is for bending state.
Substrate 100 in LED filament 10 is three, and shape triangular in shape distributes.Also can be other quantity according to the substrate of actual conditions LED filament 10, form the shape needing.
It is pointed out that according to actual conditions LED filament 10 and can be many, many LED filaments 10 adopt the mode of series connection or series and parallel combination to connect.LED bulb 30 also can be applied LED filament 20.
See also Fig. 5, it is the structural representation of the LED bulb 40 of LED filament 10 shown in Another Application Fig. 1.
LED filament 10 is two and is connected in parallel, and the substrate 100 in every LED filament 10 is four, and is arranged in W shape.LED bulb 40 also can be applied LED filament 20.
The model that it is pointed out that cell-shell 700 can be A type, G type, P type, Type B, C type, T-shaped etc.Lamp holder 600 can be E type, Type B, GU type, GX type, GZ type etc.Driver 620 can be packed in lamp holder 600 by casting glue.Between cell-shell 700 and lamp holder 600, can utilize binding agent to be fixed.
Above-mentioned LED filament 10,20, by the wire 200 of can destroying or force to yield, LED filament 10,20 is according to circumstances bent into and needs shape, and then make the substrate 100 of multiple encapsulation fluorescent glues 500 distribute as required, the light that the LED bulb 30 of applying LED filament 10,20 is sent is more even, more approaches the illumination effect of incandescent lamp.Due to the setting of the wire 200 of can destroying or force to yield, be difficult in assembling process because the stressed damage inefficacy of LED filament 10,20 causes the production yield of LED bulb 30,40 low.Multiple luminescence unit 400 series connection are arranged on strip substrate 100, and LED filament 10,20 lighting angles are larger, and brightness is better, thereby makes illuminating effect better.Substrate 100 can be printing opacity or light tight material, makes the lighting angle of LED filament 10,20 selectively higher, and then increases the application space of LED filament 10,20 and LED bulb 30,40.Wire and electric lead-out wire are directly attached on substrate 100, have simplified the structure of LED filament 10,20, and order assembling is simpler.In addition LED bulb 30,40 can adopt many LED filaments 10,20, has further increased the versatility of LED bulb 30,40.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
