Abstract
The metal-packed integrated LED display includes light guide plate and metal casing. The light guide plate includes rough light dispersing layer in both right and reverse sides or rough light dispersing signs and LED assembly around the palte. The metal casing incldues sign-shaped windows in both right and reverse sides and transparent packing layer at the windows. The device has high light emitting efficiency, high light brightness and clear display. It may be used safety in sand storm, acid, alkali, inflammable and other harsh environment and is especially suitable for used in overhead hung double-sided display.
Description
Technical field
The present invention relates to a kind of is the panel display apparatus of light source with the light emitting diode.
Background technology
As everyone knows, luminous show label is used to the various occasions of indoor and outdoor widely, exists that power consumption is big, the life-span is low, shows problems such as the low and adverse environment resistant difference of icon output optical efficiency for the traditional luminous display unit of order up till now.Existing important breakthrough of LED material and develop rapidlys such as domestic and international in recent years super brightness is green, green, blue, red are called the novel photoelectric sub-light source by domestic and international expert.Monocrystalline LED luminescence chip is generally 0.2 * 0.2-0.3 * 0.3mm
2, be very little pointolite.In order to give full play to the LED performance characteristics, take outline packages to change light distribution usually, as use lens packages, make matrix plane display module etc. with plastic injection-moulded framework.The demonstration icon of above-mentioned display module and led chip working point substantially all are correspondingly to become the area source difficulty by pointolite together, influence LED to flat thin type development.Another kind of flat panel display product adopts fluorescent light display board etc., utilize the icon groove of display board processing, reflection causes feint contrast to show to groove to make lighting source, or utilize paste text to become not illuminant colour film, carve the scatter light profile line that light source appears in the uneven surface fine rule at its peripheral profile and show.It is bigger than normal that above flat panel display product all exists the fluorescent light power consumption, the low and low shortcoming of demonstration icon output optical efficiency of life-span.
Summary of the invention
Metal Envelopment Make Up Integrated Led Display Unit of the present invention can solve high performance lED successfully is converted into the thin type area source display of high efficiency light-emitting by pointolite, and can reliably use in rugged surroundings.
But Metal Envelopment Make Up Integrated Led Display Unit solution of the above problems of the present invention is as follows: this device is made up of light guide plate and bilateral metal wrapping shell, the pre-shrinkage pool of all or part of equidistant prefabricated several cylinders lens of the peripheral side of light guide plate, and in establish the LED luminotron, described LED luminotron becomes parallel sensing with the light guide plate two sides; Described light guide plate two sided is coarse diffusion layer or coarse astigmatic icon, described light guide plate is packaged in the bilateral metal wrapping shell of front and back, described bilateral metal wrapping shell front shroud, bonnet place have the icon window, and this icon shape window can be that single or double is corresponding with icon with coarse astigmatic luminescent layer on the light guide plate; The window place of described front and back panel is by hot extrusion or be filled with the optical resin material sealant; At bilateral metal wrapping shell front shroud, the sticking card of back cap surface transparent protective film is arranged.
Aforesaid Metal Envelopment Make Up Integrated Led Display Unit, described light guide plate can be organic material polymethyl methacrylate or polycarbonate homogenous material layer.
Aforesaid Metal Envelopment Make Up Integrated Led Display Unit, described light guide plate periphery is not established LED luminotron side can glue obedient one deck reflector layer.
Aforesaid Metal Envelopment Make Up Integrated Led Display Unit can inject the epoxy type optical resin gum between cylindrical lens top shrinkage pool that described light guide plate periphery is prefabricated and the LED assembly.
Aforesaid Metal Envelopment Make Up Integrated Led Display Unit on the described coarse diffusion layer, also can cover the luminous paint resin bed.
The LED light output of Metal Envelopment Make Up Integrated Led Display Unit of the present invention has high directivity, makes its luminous overwhelming majority run into the light guide plate surface, become incident angle greater than the reflection critical angle, and it is reflective to produce the air minute surface, improves leaded light efficient; This device with luminous paint by resin-bonded on layer tabula rasa, produce efficient astigmatic luminescent layer, luminous output efficiency height, luminosity height, the clear distinctness of display performance; This device utilizes hot extrusion optical resins such as polymethyl methacrylate to be encapsulated in the window place of metal wrapping shell two sides, and with the metal wrapping shell with the combination of grafting form, and fill with fluid sealant, can in sand and dust, acid, alkali, rugged surroundings such as inflammable and explosive, use safely.

Embodiment
Embodiments of the invention can be referring to accompanying drawing:
At first, prefabricated light guide plate: light guide plate is complementary with the LED size: the LED that the LED that the LED of φ 3 joins thickness light guide plate, the φ 5 of 5mm joins 6-8mm thick light guiding plate, φ 2 joins the 3mm thick light guiding plate.Light guide plate 6 can be organic material polymethyl methacrylate (PmmA) or polycarbonate (PC) homogenous material layer, also can be that substrate is (PmmA), the surface is for PC or be coated with the organic silicon wear resistant thin layer, inorganic optical sheet glass and organic substrate can also be formed in surface recombination.At prefabricated cylindrical lens top, its both sides shrinkage pool 7, and light emitting diode is wherein pre-buried, inject the epoxy type optical resin gum, optocoupler coupling and optical sheet efficiently conduct between assurance led chip and light guide plate, if the one-sided LED luminotron of establishing, opposite one side can obedient one deck reflective membrane.Single or double outpours coarse diffusion layer 4,10 by mould in the light guide plate two sides.
Secondly, make the metal wrapping shell by the light guide plate size, this metal wrapping shell is made up of the front shroud bonnet, and they play the effect of encapsulation light guide plate with grafting form wringing fit.Adopt mould punching press or plasma NC cutting to go out the window of icon shape on front shroud, back cover panel, this window can seal with high-ductility white or look film nylon or the hot extrusion of high density Polyvinylchloride or filling mode.Described metal wrapping shell can adopt sheet metals such as aluminium, iron, steel, and the little 0.4-0.6mm of the comparable front shroud size of back cover is convenient to the coupling assembling.The metal wrapping shell is outer can to spray one deck lacquer painting.
This device can be made into thickness 0.6-1.0cm's, can directly paste wall and mount use, need not to destroy building structure, can single, double shows luminous display board, is used for hanging use especially thoroughly in the air.
