The first is the high light efficiency : the light effect for the led electronic display can be an important indicator of energy-saving effect, at present, China's light effect needs to be strengthened, to really achieve high efficiency, from all aspects of the industrial chain to resolve related Technical issues, then how to achieve high luminous efficiency? This article will be specifically for the extension of the epitaxial, chips, packaging, lighting and other aspects to be resolved technical issues.
1. Improve internal quantum efficiency and external quantum efficiency.
2. To improve the efficiency of the package and reduce the junction temperature.
3. Improve the lamp light extraction efficiency.
Followed by the high color of the point of view : led electronic display light color quality, including color temperature, color rendering, light color fidelity, natural color light, color tone recognition, visual comfort and so on. Here we only discuss to solve the color temperature and color problems. Production of high color rendering led light source, will lose more light efficiency, so in the design to take care of these two factors. Of course, to improve the high color must also consider the RGB three primary colors to achieve. Here I also have three ways:
1. Multi-color phosphors.
2.RGB multi-chip combination.
3. Phosphor plus chips.
Once again, from a high reliability : mainly including the failure rate, life expectancy and other indicators. However, there are different understandings and elaborations in the application. High reliability refers to the ability of the product to fulfill the specified functions under the specified conditions and within the stipulated time. led failure categories are mainly serious failure and parameter failure. Lifetime is a measure of product reliability. : Generally refers to the statistical average, for a large number of components, led device life is the meaning of this description. However, the factors that affect the reliability of led display products are chip manufacturing, packaging, thermal resistance, heat and so on. Since it comes to this, I hope enterprises led display products in the implementation of total quality control on the basis of two requests:
1. Reduce the failure rate.
2. To extend the wear and tear of failure time.
Finally, reduce the cost of the product : At present, many consumers buy the LED display that prices are too high, so the fight for this led many entrepreneurs have taken appropriate measures to reduce costs in addition to mass production , Mainly from the technical measures to reduce costs, ways. Mainly in the epitaxial chip, package, drive, cooling and other areas to reduce costs, so as to fundamentally solve the cost of led display products. Specifically from the following four aspects:
1. Epitaxial chip cost reduction methods.
2. Packaging methods to reduce costs.
3 ways to reduce costs of lighting.
4. Other supporting costs to reduce.
A Split Hopper Barge (SHB) is a vessel with a large open hold, used to load and transport dredged material. The Barge is loaded by a Cutter Suction Dredger or by a Backhoe Dredger. The barge is self-propelled, and sails to the deposit area, where it unloads the soil. The vessel consists of two halves, and unloading is done by opening, or `splitting`, the two halves, and depositing the soil on the seabed.
A hopper barge is a kind of non-mechanical ship or vessel that cannot move around by itself, unlike some other types of barges, that is designed to carry materials, like rocks, sand, soil and rubbish, for dumping into the ocean, a river or lake for land reclamation.Hopper barges are seen in two distinctive types; raked hopper or box hopper barges. The raked hopper barges move faster than the box hoppers; they are both designed for movement of dry bulky commodities.
Photo of our Split Hopper Barge:
Split barges serve the same purpose, but instead of a door in the hull's bottom, the hull of the whole barge splits longitudinally between the end bulkheads. The vessel consists of two major parts (port and starboard halves), both are mostly symmetrical in design. Both parts of the vessel are hinged at the deck and operated by hydraulic cylinders. When the vessel splits the load is dumped rapidly, which means the barge has to be very stable in order not to capsize or otherwise get damaged.
