With the development of social economy, the energy consumption of the lighting industry has become more and more, and the new generation of lighting technology of energy saving and environmental protection--LED (LightEmitting Diode) light source technology has become a strategic new technology for the development of relevant countries and companies. In 2010, the scale of China's LED industry has exceeded 120 billion yuan, and it has entered a period of rapid development. However, most of the enterprises in China's LED lighting industry are still concentrated at the low-level level, so the development of low-cost independent intellectual property rights. The high-performance new packaging materials meet the development requirements of China's LED industry.
Currently, one of the most commonly used methods in the world to obtain white light is to mix the blue light emitted by the chip and the yellow light emitted by the blue light-emitting phosphor of the chip to generate white light, such as a blue GaN LED chip and a yellow Y3Al5O12:Ce3+ phosphor. Combination [1]. However, this method of producing white light has two main disadvantages [2]: 1 The refractive index of the phosphor YAG crystal is 1.836 (when the wavelength is 588 nm), and the refractive index of the epoxy resin and the silica gel applied to the LED package. Then it is no more than 1.55; in addition, the particles of the phosphor are usually around 10 μm. The difference in refractive index between the phosphor and the encapsulating material and the large particles of the phosphor result in severe light scattering, resulting in light loss. 2 The organic material used for packaging is in an environment of high temperature and short-wave radiation, which is prone to aging failure and causes LED failure. 3 Because the thermal resistance of the contact surface of the phosphor with the epoxy resin or the silica gel is large, the heat is concentrated, and the epoxy or the silica gel is easily carbonized and blackened, thereby causing the LED to fail.
Due to the above various reasons, the development of new fluorescent conversion composite materials has become a research hotspot for researchers. The current research hotspots mainly focus on the following aspects: glass ceramics containing YAG (Y3Al5O12: Ce3+) nanocrystals, Eu2+ doped silicate nanocrystals containing glass ceramics. Transparent glass ceramic is obtained by partial crystallization of inorganic precursor glass. It is a composite material composed of an oxide glass phase and a nanocrystalline phase. It combines the advantages of optical crystals and optical glass, and can have a spectrum similar to or better than a crystal. Performance, but similar to the obvious advantages of glass material preparation technology, low cost and high concentration doping, and easy to make large size high power and shaped devices; in addition, its mechanical properties and thermal stability (mainly depends on Glass phase substrates, such as SiO2), are also superior.

Transparent LED display screen
Transparent Led display is a creative design and upgrade version of Outdoor Led Display screens. It is made by DIP Led strip.
products have features of light weight, energy-saving, high transparency, fast installation and easy maintenance. With advanced and top level of led diode , Priva Led's Outdoor transparent LED Display have low power consumption and high brightness. In this ways, It is very stable and durable during lifetime.
For better understanding Led curtain display main advantages,
High Water-Proof grade applied with IP65 water-proof standard, make your screen working perfectly without problems even in heavy rain.
Light-weight cabinet The cabinet is about 5-8 KG per square meter, 60% less weight compared with traditional tile and have greatly reduce the load bearing pressure of the structures.
High transparency rate Louver design, make the transparency rate up to 72%, and this design greatly satisfied people`s curiosity to see outside from inside.
High brightness8000nits for P25, could be used absolutely for outdoor under strong sunshine.
Fast & easy installation No need steel structure, Solid and simple assemble style, make installation and maintenance quick and easy. It stands firmly even in big wind.
Installation Steps
Installation Steps
1 Fitting the steel structure: fitting it on the wall firmly
2 Attach the U-Tile frame to the structure firmly
3Lock the frame on the structure by screws
4Hanging the upper right hooks of the cabinet to the card slot of the right U-tile Frame.
5
Buckle the left position pins of the cabinet to the location holes of the left side of the U-tile frame
6 Aim at the screw holes for the front service installation, fitting 6 screws on the U-tile frame through the cabinet from the front.
(This is a procedure of front service, this cabinet support also available for back maintenance)
7 Then finished installation for one cabinet. The same as the next cabinet.
8 Cable Connection.
Connect the male-plug (with cable) of the next cabinet to the female-plug of its upper cabinet firmly.
9 Using the same mode to finish the rest connection (five-pins cable), then the installation work for a complete LED display is finished.
After-sale maintenance
1 The cabinet support single trip maintenance. If there any bad LED lamp or damage on single strip, you can remove the strip separately without take out the cabinet and control box.
2, Cabinet support front & back installation and maintenance. If there any problem on single cabinet, you can remove the cabinet from the front & back of the screen.
3 ,If there damages on the control box, you need remove the cabinet and open the cover of the power supply box to do repair & exchange work.
Cabinet size:
Package: Wooden case 1 for 10 led strip curtain cabinets.
Package size:
This outdoor LED Strip curtain display series product are widely used for building facade, behind of glass wall, in front of glass wall, led billboard& signs and on top of building.
