Description
Technical field
The invention belongs to LED illumination technology, and in particular to a kind of straight emitting led formation light.
Technical background
For the prerequisite formation light of air formation night flight, current its light source mainly uses EL luminescent screens.EL luminescent screens
Advantage be brightness uniformity and can arbitrarily bend, have the disadvantage to send out a kind of the light of color, be have lost to leach infrared light
Half efficient lighting area；And from the point of view of the feedback for using at present, luminescent screen brightness is also not enough.
Using infrared, green straight emitting led alternately solid matter, spread even light by the way of, can both meet brightness uniformity and can
With the requirement of any bending, can solve the problem that again can not same light-emitting zone can not replace rubescent outer, two kinds of light of green lack
Fall into, while brightness can also be increased substantially.
But because formation light is very thin in itself, existing routine is directly emitting led to be difficult to be arranged on realization in so thin lamp body
Even light, therefore prior art generally still uses EL luminescent screens.
The content of the invention
The purpose of the present invention is：In order to solve prior art formation light efficient lighting area deficiency, luminescent screen luminance shortage
Problem, there is provided a kind of brightness is high and the uniform straight emitting led formation light of diffusion.
To achieve these goals, the technical scheme is that：A kind of straight emitting led formation light, it is characterised in that branch
Plate 1 in support, diffusion panel 6, diffusion barrier 10, optics silica gel 9, the light source printed board 4 of filling spread powder, wherein, in support plate and
The optics silica gel and light source printed board for filling spread powder are arranged between base plate and diffusion panel and set, and plate surround filling in support
The optics silica gel of spread powder and light source printed board are set, light source printing be arranged on filling spread powder optics silica gel and base plate it
Between.
Light source printed board 4 is provided with spaced red LED and green towards the optics silica gel side of filling spread powder
LED array.
Between light source printed board 4 and base plate 2 and support between plate and base plate by epoxy resin glue sticking.
Fill and be provided with diffusion barrier between the optics silica gel of spread powder and diffusion panel.
In diffusion barrier and support two-sided glue sticking is bonded between plate and panel by without base material.
The thickness of light source printed board 4 is no more than 0.2mm.
Base plate is not more than 4mm with the integral thickness of panel 6.
The solution have the advantages that：Straight emitting led formation light of the invention is keeping uniform in light emission, flexible premise
Under, realize efficient lighting area increase be twice, luminosity is content with very little requirement, and efficiency is optimal, efficiently solves existing
Technology formation light efficient lighting area is not enough, the problem of luminescent screen luminance shortage, with larger actual application value.
Brief description of the drawings
Fig. 1 is overall structure diagram of the invention.
Fig. 2 is plane figure schematic diagrames of the LED of the invention in printed board.
In Fig. 1, plate, 2- base plates, 3- epoxide-resin glues, 4- light sources printed board (PCB), 5- green LEDs, 6- faces in 1- supports
Plate, 7- bond optics silica gel, 10 diffusion barriers that double faced adhesive tape, 8- red LEDs, 9- fill spread powder without base material.
Specific embodiment
Below with reference to accompanying drawing and implementation, the present invention is further illustrated.
Fig. 1 is referred to, the straight emitting led formation light of the present invention includes plate 1, diffusion panel 6, diffusion barrier 10, filling in support
The optics silica gel 9 of spread powder, light source printed board 4.Wherein, optics silica gel of the plate with filling spread powder and light source printed board in support
It is arranged between base plate and diffusion panel and sets, and plate sets around the optics silica gel of filling spread powder and light source printed board in support
Put, light source printing is arranged between the optics silica gel of filling spread powder and base plate.
The light source printed board 4 towards filling spread powder optics silica gel side be provided with spaced red LED and
Green LED array.As shown in Fig. 2 being the staggeredly solid matter mode of infrared LED, green LED in light source printed board (PCB) in figure
And the optimal spacing of suitable ultra-thin (no more than 4mm) the even light of lamp body, 8 infrared LEDs, 5 green LEDs, 4 light source printed boards (PCB), this
The arrangement of sample can be well mixed light.
Between the light source printed board 4 and base plate 2 and support between plate and base plate by epoxide-resin glue (3M
DP760) it is bonded.In curve generating, the shear strength of epoxide-resin glue, it is ensured that ascending stair will not resilience.
Diffusion barrier is provided between the optics silica gel and diffusion panel of the filling spread powder.The effect of diffusion barrier is to make institute
The light of transmission is broken up, and plays the purpose of even light, while ultra-thin (less than 0.5mm) is required, to ensure to spread even light effect.
By Nian Jie without base material bonding double faced adhesive tape (3M F9469) between plate and panel in the diffusion barrier and support, to avoid
Excessive glue, makes uniform light board strike-through, influences printing opacity.
The thickness of light source printed board 4 is no more than 0.2mm, and base plate is not more than 4mm with the integral thickness of panel 6.So that
Under the conditions of ultra-thin, field requirement could be met.
LED formation lights of the present invention will without base material bond double faced adhesive tape developed on panel it is whole, then by alignment pin will support in
Plate is bonded with panel；Used as positioning, sticking propagation film simultaneously develops whole, bubble-free, is then injected into the middle fluting of plate using in support
The optics silica gel of 30% spread powder is filled, light source printed board (containing infrared and green LED) is stained with after discharge bubble and is wiped remaining glue off simultaneously
Solidification；The last plate another side in support is stained with base plate, and is put into the compression shaping of curve generating frock, and the normal temperature cure time is not small
In 28 hours.After the completion of lamp body integrally curing, processing and forming is taken out and carried out.Spread powder is filled in optics silica gel by adjusting
Infrared and green LED arrangement in concentration, light source printed board, coordinates diffusion barrier and panel dispersion, and can reach makes LED emergent lights
Uniform effect.Simultaneously as employing ultra-thin printed board (0.2mm is thick) can bear certain flexural deformation so that formation light
Body can integrally bend (before adhesive solidification, use frock prebuckling), with larger actual application value.
