Support (1):
Support plays the effect supporting and protecting whole luminescent device.Support uses hard material (such as plastics or metal
Deng) make whole luminescent device form specific rigidity body；Support can be plane, curved surface etc.；Profile can set as required
The shape that meter squarely, circle etc. is different；Support can be medium altitude groove assembling structure, it is also possible to be other shape and structure；Also may be used
To be the band loose structure by strong muscle, this porous is changeable, can be square, circular or honeycomb type etc..
Shelf layer can be at the top of long afterglow layer (4), or the bottom of line layer (2), it is also possible in long afterglow layer (4)
And between LED illuminator (3).
Line layer (2):
Line layer plays the effect LED illuminator in whole device coupled together.
Line layer can use the PCB of rigidity or the FPC printed IC board of flexibility as required；Can also use
Wire is directly connected to each other.Certain electronic component can be had on line layer to weld in circuit (such as resistance).
The circuit of line layer can use series, parallel or series connection and the pattern of parallel combination according to actual needs.
When line layer uses wiring board when, according to practical situation needs, wiring board can be the wiring board of monolithic, also
Series, parallel or series connection and the pattern of parallel combination can be used with two or more wiring board.
LED illuminator (3):
LED illuminator can select various business LED illuminator as required, and LED illuminator can use as required
The monolithic paster LED chip that luminous tube that the Lamp mode of single package encapsulates, SMD mode encapsulate, it would however also be possible to employ COB mode
The LED chip etc. of integration packaging.
The first-selected white good to the stimulation effect of long after glow luminous material of LED illuminator, purple, blue light luminous body.
LED illuminator can be one or more than one LED chip is welded on line layer as the most regularly arranged,
Can be according to the structure situation of support when LED illuminator is multiple when, can be with integrated distribution in a region, it is also possible to
Single or multiple LED luminescence chip subregion is used to be distributed.It is arranged on line layer, when being transversely or longitudinally 1, another one
It is formed for a ribbon when of axially mounted a lot of LED illuminator.When horizontal and vertical, plurality of LEDs luminescence crystalline substance is all installed
Body just can make tabular luminous body.Certain word can also be installed as required or pattern arrangement is arranged on line layer
On.
Long-persistence luminous layer (4):
Long-persistence luminous layer is that the mixture solidification of long-afterglow material and resin glue forms.Select long remaining according to actual needs
The glow color of brightness luminescent material, granularity and afterglow property.The aluminate long afterglow luminescence material of prioritizing selection stable physical property
Material.
Resin needs to select that transparency percent of pass high, light is high, contractility is little, good weatherability, water-tolerant, color inhibition,
Liquid resin；Resin can be one-component can also be many components.Such as: organosilicon, PU type, acrylic type, epoxy type, no
The various resin such as saturated resin.
The resin mixed can mix thing as required uses cast, instillation or injecting method curing molding at LED
Emitter surface, it is also possible to the resin mixed is mixed thing and is poured in certain vessel, when mixture the most all solidifies when
LED illuminator is embedded or partially embedded in long-persistence luminous layer entirely.
Sealant (5): play the effect sealing this LED, is the infiltration of device inside isolation moisture, thus
Protect LED and the circuit of this device inside.According to support and the needs of the structure of each layer, sealant is not essential.
External wire (6): play the interconnection function with circuit controller or external circuits.
This utility model uses the finished product LED of commercialization, long-persistence luminous with directly encapsulating in LED wafer
The method of material is compared has simple easily shape, can be with individual character manufacturing long afterglow LED.Can make each very easily
Plant the long afterglow LED of size shape.
Case study on implementation one:
Such as Fig. 2, a kind of long afterglow LED luminescence wall lamp
1 be top be the hollow white plastic casing support of high transparency, this plastic casing support plays support and protects
Protect the effect of whole luminescent device.
2 is the pcb layer of a rigidity, and the LED in whole wall lamp is welded on wiring board.Use parallel circuit
Pattern.Accordingly even when there is one the faulty illumination effect being not to affect very much whole wall lamp of LED illuminator in end.
3 is 16 single power 0.1 watt, blue light-emitting, uses the LED luminescence chip of SMD packaged type, and point two rows are welded on
On pcb layer.
4 is long-persistence luminous layer, by high brightness aluminum silicate long afterglow luminous material and the transparent epoxy resin of about 100 mesh
After mixing, it is cast on LED luminescent layer 2, thickness about 5～6 millimeters；Treat that the mixture of luminescent material and resin is fully cured
After, this device just becomes a firm entirety.
5 is sealant, and circuit board and LED luminescence chip etc. are sealed in the internal stent of whole hollow.
6 is that external wire is directly connected on controller or switch.
The wall lamp using this utility model to make has simple in construction, luminous soft, overall firm.After turning off the light night,
This wall lamp can be with continuous illumination, and therefore when people's toilet on getting up midnight when, this wall lamp still provides suitable
Low illumination, thus also will not should be while the walking being convenient for people to needs turn on light impact ensuing sleep.
Long-afterglow material is cured to the top of commodity LED illuminator and forms one with long afterglow function by this utility model
LED.Thus the high brightness capabilities of common LED can keep again phase power-off when during the existing energising of this long afterglow
Performance to low-light level.This LED, has self-luminescence function after a loss of power.
