Description
Technical field
The invention belongs to buildings in general structure field, relate in particular to the glass curtain wall that can be applicable to building on realize photoelectricity brightening decoration of a kind of LED of employing as light emitting source.
Background technology
LED (Light Emitting Diode) is a light emitting diode, forms by PN layer and central luminescent layer, and along with luminescent layer material difference, its glow color difference.
Since early 1990s, nitride LED produced, the LED luminous efficiency had had qualitative leap.The successful development of blue-ray LED then makes white light LEDs become possibility.The successful development of the physical and chemical processes of white light LEDs and technology provides reliable assurance for realizing shades of colour led light source product.
In recent years, the successful solution of the processing procedure of great power LED and corresponding heat dissipation problem thereof has more promoted LED toward more application development.Because LED meets the RoHS (harmful substance uses restriction to guide) of European Union's appearance in 2004, be Green Product in addition, development prospect widely arranged than traditional lighting light source.
Now, its main application fields of LED comprises: preceding according to the decorum, and illumination (indoor and outdoors), demonstration (FPD, front end show illuminator), cab signal lamp, sensor (automobile-used, outside traffic pavement behavior etc.) etc.
For better being penetrated in the above-mentioned field, certainly will require LED to develop to line source, area source by traditional spot light.
At present, LED has a variety of as the building decoration illumination light source, roughly can be divided into following several:
1, with the paster LED be the use of the lampion string of light source, it mainly is made up of plain conductor and LED device, can directly the LED device electrode be connected on the lead, then lamp is ganged up certain mode and is pasted on the building that will decorate, keeps supplying power supply and gets final product.
This easy operating simple in structure, but decorative effect is not good, and especially lead hung on the building outside overall appearance of building was caused very big influence daytime.
2, be the gradual change wallboard or the wall bar of backlight with LED, its thickness is bigger, and transparency is not high, and it is complicated that it drives control, and cost is also than higher;
3, do to be assembled into shot-light by LED behind the module;
4, side-light type LED transparent light source, it mainly is made of glass plate, LED device, lead etc., and the LED device is installed in glass plate on every side as the sidelight source, and luminous afterwards light being imported to again of light emitting source becomes LED transparent area light source in the glass plate.
Do like this and have the following disadvantages: can't show decorative pattern, can only be single light source; LED cooperates difficulty big with optics between the glass, when using, all will do corresponding optical design to glass and LED at every turn, to reach the optics requirement, makes troubles to application like this; In addition, because the led light source influence of fading, its area source size is received certain restriction, and the light uniformity is also received certain limitation.
In sum, how to carry out LED and make transparent LED area source, make it keep both artistic and practical in not luminous, producing corresponding figure pattern illumination again when luminous, can't to be subjected to size constrained be the current problem that will consider.
The day for announcing is on February 23rd, 2005, and notification number is the Chinese patent of CN 2680662Y, discloses a kind of " LED interlayer illumination and decoration glass ", and it is folded with the cementing layer bonding by clear sheet and forms; Its described clear sheet and cementing layer are set to bilayer respectively, are provided with the conducting wire in double-deck cementing layer therebetween, and it is provided with at least one LED, and two ends, described conducting wire and peripheral hardware power supply join.

Specific implementation method:
(1) processing of the transparent conducting coating on transparency carrier surface and pattern etch:
Two kinds of embodiments are arranged:
First kind: the substrate that directly will scribble transparent conducting coating cleans up, and will need current-carrying part to carry out mask then, and through acid etch, non-conducting portion etches away, and the corresponding pattern that just comes out constitutes the transparent electrode coating with certain graphic structure.
In addition can be according to the complexity of pattern mask repeatedly, multiple etching.
Second kind: earlier according to designed pattern, on substrate, do not need current-carrying part to carry out mask, in the place of needs conduction transparent conducting coating is coated on the transparency carrier with methods such as sputters then, can be carried out repeatedly mask multiple etching according to the design needs equally.
(2) led light source assembling:
Design according to transparent conducting coating, led light source is connected on the corresponding transparent conducting coating pattern according to both positive and negative polarity, led light source can stand directly on the transparent conducting coating pattern of substrate surface by the form of a glue with conducting resinl, then, select to be cured under the different temperature according to the difference of conducting resinl; Also can use conductive tape directly led light source to be sticked on the transparent conducting coating of glass, the latter operates simple and easy, but cost is higher.
(3) apply the respective drive curtage, can realize the illumination of transparent light source.
Because the present invention is by the optical texture on the change transparency carrier, thereby the light that led light source is penetrated can partly penetrate from the upper strata transparency carrier, another part light penetrates from lower floor's transparency carrier.The observer can see the two-sided light effect that goes out simultaneously at the upper and lower faces of light source like this.Simultaneously, it has adopted transparent conducting coating and the luminous form of straight-down negative LED, strengthened the transparency of the decorative constructure of wanting greatly, when not luminous by day, can not influence its exterior appearance, can satisfy large-sized lighting requirement, the illumination effect of the etching pattern control LED by changing transparent electrode on transparent substrate can not be subjected to the influence of the size of transparency carrier.
For those of ordinary skills, can make various possible being equal to according to foregoing description and replace or change, and all these changes or replacement all should belong to the protection domain of claims of the present invention.
The present invention can be widely used in fields such as the glass curtain wall of building or building and ornament materials.
