Description
Technical field
The present invention relates to a kind of display device structure, particularly relate to a kind of white light display ray structure.
Background technology
Known white light display as shown in Figure 1, blueness or green emitting assembly 200 are installed on the substrate 100 of printed circuit board (PCB), the reflection housing 400 that to reserve hollow out 410 again is installed on the printed circuit board (PCB) 100, the fluorescent material 300 that will be mixed with yellow or red fluorescence powder afterwards is filled in hollow out 410, be full of reflection housing 400 inside, even the through hole of reserving on the infiltration printed circuit board (PCB) 100 and flow to the another side of luminescence component 200, coat luminescence component 200 and printed circuit board (PCB) 100 fully.Treating becomes the white light display that can't decompose after fluorescent material 300 sclerosis.But all assemblies of the white light display product of above-mentioned formation all are packaged in fluorescent material 300 inside and can't decompose, and can't carry out heavy industry when having the situation of luminous color development inequality to take place as product, cause damage.
In addition, known white light display is filled with the fluorescent material that is mixed with yellow or red fluorescence powder and is completely reflected enclosure interior, but the light that blueness or green emitting assembly send only is mixed into white light by the yellow or the red fluorescence powder of openwork part, be filled to the fluorescent powder of sneaking in the fluorescent material of reflection enclosure interior any effect does not take place, form the unnecessary waste of fluorescent powder.
Summary of the invention
The object of the present invention is to provide a kind of white light display structure, when the unequal unfavorable condition of luminous color development took place, the part that only need change the bad origin cause of formation got final product.
Another object of the present invention is to provide a kind of white light display structure, save the consumption of fluorescent powder, reduce unnecessary waste.
To achieve these goals, the invention provides a kind of white light display structure, comprise that a substrate, a luminescence component are located at this substrate, one light transmissive material coats this luminescence component, one housing has a hollow out, and one fluorescent material be filled in the hollow out of this housing, this fluorescent material is the light transmissive material that contains fluorescent powder.Wherein the combination of substrate, luminescence component and light transmissive material is removably to be fixed in the combination of housing and fluorescent material, and the light that luminescence component sends outwards sends white light by fluorescent material.
Wherein substrate is removably to be fixed on the housing, can also close substrate and housing rivet hot fixing.For example be that the combination of substrate, luminescence component and light transmissive material is fixed in the combination of housing and fluorescent material in the rivet hot mode of closing.
Luminescence component can be the blue-light-emitting assembly.Fluorescent powder can be yellow fluorescent powder or red fluorescence powder, and it does not all break away from spirit of the present invention and scope.Preferably, substrate and luminescence component are direct packaged chips (chip on board).And light transmissive material can put the glue mode or the brush coating mode coats luminescence component.
Luminescence component preferably comprises a surface adhering light emitting diode (SMD LED).In addition, in one embodiment, luminescence component can adopt blue LED or green LED.
Describe the present invention below in conjunction with the drawings and specific embodiments, but not as a limitation of the invention.

410 hollow outs, 420 light transmissive materials
Embodiment
As shown in Figure 2, white light display structure of the present invention comprises substrate 100, luminescence component 200, fluorescent material 300, housing 400.Substrate 100 comprises a printed circuit board (PCB).Luminescence component 200 is blueness or green emitting assembly, is positioned on the substrate 100.Housing 400 comprises hollow out 410.Fluorescent material 300 is positioned at hollow out 410 for comprising the light transmissive material of yellow or red fluorescence powder, separates housing 400 interior or exterior spaces, prevents that the dust aqueous vapor from entering.Luminescence component 200 is positioned under the hollow out 410, and the light that luminescence component 200 sends is mixed into white light by the fluorescent powder in the fluorescent material 300, penetrates by hollow out 410.Between housing 400 and the substrate 100, can adopt variety of way to be fixed, but take situation about can decompose again into account, it is preferable the fixed form that decompose again such as to close with rivet hot.
As shown in Figure 3, white light display structure of the present invention also can comprise a light transmissive material 420, is coated on luminescence component 200.Its manufacture method is the making flow process of the carrying out housing 400 parts respectively making flow process with substrate 100, luminescence component 200 parts, and the finished products with two making flow processs are combined into white light display structure of the present invention again.The making flow process of housing 400 parts is to make after the housing 400 in modes such as injection moldings, and fluorescent material 300 is filled in hollow out 410, treats that its sclerosis promptly finishes the making flow process of housing 400 parts.The making flow process of substrate 100, luminescence component 200 parts is with after luminescence component 200 and substrate 100 electric connections, be coated on luminescence component 200 and substrate 100 with mould, light transmissive material 420 is filled in the mould, coat luminescence component 200, substrate 100, treat its sclerosis, peel of mould is promptly finished the making flow process of substrate 100, luminescence component 200 parts.Two make the combination of the finished product of flow processs, described in Fig. 2 embodiment, can adopt variety of way to be fixed, but take situation about can decompose again into account, and it is preferable the fixed form that decompose again such as to close with rivet hot.Because of light transmissive material 420 coats luminescence components 200, substrate 100, separate luminescence component 200, substrate 100 contacts with the outside, prevent that the effect that the dust aqueous vapor enters is better.
By the invention described above preferred embodiment as can be known, the present invention has following advantage:
When product has the uneven unfavorable condition of luminous color development to take place, because of housing 400 and substrate 100 detachably decompose, get final product so change bad part whereby, for example, when fluorescent material 300 causes light transmission not good because of sneaking into foreign matter, change the housing 400 that comprises fluorescent material 300 and get final product.Perhaps, when luminescence component 200 was unusual, substrate 100 parts of changing installing luminescence component 200 got final product.
In addition, fluorescent material 300 only is filled in the position of hollow out 410 and underfill housing 400 inside, and the light that luminescence component is sent blendes together white light, therefore can save the consumption of fluorescent powder, reduces unnecessary waste.
Can carry out application implementation miscellaneous in technological thought scope of the present invention, for example, be that example describes with the seven-segment display in the diagram, but the kenel of white light display is not limited, and also can be applicable to the various displays of dot matrix type etc.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
