Are ceramic lamp shades useful?

Since the mid-1980s, there have been monochrome and multi-color displays, initially text or animation screens. In the early 1990s, the development of electronic computer technology and integrated circuit technology enabled the realization of video technology of LED display screen, and TV images Machinable Ceramic were directly displayed on the screen. Especially in the mid-1990s, blue and green ultra-high-brightness LEDs were successfully developed and put into production quickly. The application of outdoor screens is greatly expanded, with an area ranging from 100-300m. LED display screens have been widely used in stadiums, squares, venues, and even streets and shopping malls. The Nasdaq full-color screen in Times Square in the United States Macor Ceramics is the most famous. The screen area is 120 feet × 90 feet, equivalent to 1005m. Made of only super bright blue, green and red LEDs. In addition, the application of securities market screen, bank exchange rate screen, interest rate screen and other aspects also accounts for a large proportion, and there has also been a great development in the information screen of highways and elevated roads recently. The application of light-emitting diodes in this field has reached a large scale, forming a new industry, and it is expected to have a relatively stable growth. The beacon light Silicon Nitride Parts has been using LED as the light source for many years, and the current work is to improve and perfect it. Road traffic lights have made great progress in recent years, with rapid technological development and rapid application development. China has about 40,000 sets of orders every year, while California in the United States has replaced 50,000 sets of traditional light sources with LED traffic lights within one year. According to the use effect, the signal lamp has obvious effects of long life, power saving and maintenance-free. The peak wavelengths of light emitted by LEDs are 630 nm for red, 590 nm for yellow, and 505 nm for green. The problem that should be noted is that the driving current should not be too large, otherwise the high temperature conditions under the sunlight in summer will affect the life of the LED. Recently, the special LED signal lights used in airports as beacons, flood lights and omnidirectional lights have also been successfully and put into use, and many parties have responded well. It has independent intellectual property rights and has been approved for two patents. It has good reliability, saves electricity, and is maintenance-free. It can be applied to various airports and replace the old signal lights that have been used for decades. It not only has high brightness, but also because of the purity of LED light color Good, especially sharp, easy signal identification.
