At present, lack of resources and energy shortage have become bottlenecks in global development. In the case of tight power supply, countries have begun to explore new types of lighting sources. Relevant research has found that LED as a light source has three advantages of energy saving, environmental protection and long life. In theory, only 10% of the energy consumption of incandescent lamps can be achieved, and energy saving is 50% higher than that of fluorescent lamps. It is packaged in a solid package and has a lifetime 10 times that of a fluorescent lamp and 100 times that of an incandescent lamp. At the same time, the LED light source has no ultraviolet light, infrared light and the like, and can avoid the secondary pollution of the fluorescent tube rupture and overflow of mercury.
LED products have huge international market space
In recent years, a wave of LED lighting has swept the world, setting off a “second revolution†in the lighting industry.
Attracted by the huge energy-saving potential of LED lighting, the United States, Japan, South Korea and other countries and Taiwan Province of China have successively launched their own semiconductor lighting industry development plans. In 2007, LED research and development levels and technical levels in Japan, Europe, the United States and other countries and regions have been greatly improved, prices have been further reduced, and the luminous efficiency of industrialized white LED devices and lighting products has reached 70-80Lm/W. Promote lighting applications in some sectors and areas.
With the vigorous promotion of energy conservation and emission reduction work and the development of new energy industries in various countries around the world, people are increasingly demanding lighting sources. LEDs (light-emitting diodes) are affected by various countries due to their energy saving, environmental protection and long life. Admired. The US Department of Energy predicts that by the end of 2012, 55% of incandescent and fluorescent lamps in the United States will be replaced by LED lights, saving $35 billion in annual electricity bills. Japan has also proposed to replace traditional incandescent lamps with LED lamps on a large scale. According to estimates, in 2010 alone, LED lighting may form a large industry of 50 billion US dollars.
On November 16, at the opening ceremony of the 12th High-Tech Fair, the reporter noticed that the lighting sources of the various halls inside the exhibition center were basically LED lamps. Although the lights illuminate those halls, there is no dazzling feeling for every visitor who walks in. Yan Shirong, executive vice president of the Shenzhen LED Industry Association, told reporters that a considerable number of LED lamps are produced by Baoan's LED companies.
LED will "illuminate" Baoan's new field of economic growth
Looking at the development of the national LED industry, Shenzhen, Shenzhen LED industry form to see Baoan.
As one of the important bases of China's LED industry, Shenzhen has more than 900 companies engaged in R&D, production and sales of semiconductor lighting technology and products, accounting for 70% of the national total and nearly 100 enterprises above designated size.
In March 2009, the Shenzhen Municipal Government listed energy-saving and environmentally-friendly emerging light sources and lighting technology LEDs as key emerging industries, and officially issued the “Shenzhen LED Industry Development Plan (2009-2015)â€, which is decided every year for 3 years. We invested more than 100 million yuan to support the development of the LED industry and build and build a global LED R&D and production base.
More than half of the companies engaged in the research, development, production and sales of semiconductor lighting technology and products in Shenzhen are from Baoan, which are distributed in the fields of substrate materials, epitaxy, chips, packaging, application industries and supporting products, covering all areas of the industrial chain. .
On November 16th, at the opening ceremony of the 12th Hi-Tech Fair, a large-screen LED display uninterruptedly broadcasted information about the exhibitors of the high-tech fair. Various wonderful visual images attracted many visitors to stop. The HD level of the picture shocked the audience. The remote control of this LED display is the LED large-screen control system BIS-6540LC produced by Shenzhen Huabei Industrial Control Co., Ltd. of Taohuayuan Science and Technology Innovation Park in Baoan District. The manager of the marketing department of North China Industrial Control Co., Ltd. told Ren Tao that the control system uses network remote control, which is convenient to manage and does not require manual duty. As a leading global industry-specific computer supplier, the high-definition network multimedia advertising machine developed by North China Industrial Control in recent years has not only demonstrated its functions in the Canton Fair's on-site information display, Baoan International Airport's flight display system, but also in major international and domestic subway stations. , shopping malls and other places also have excellent performance.
Most of the LED lighting industry enterprises in Baoan District are domestic key and key enterprises, with a large industrial scale, forming a relatively concentrated industrial structure. Leading enterprises have strong innovation and development capabilities, chip design and production capacity, and are engaged in application. Most of the products produced by the company have strong technical development and new product design capabilities.
Since entering the "Eleventh Five-Year Plan", the investment in the LED lighting industry in Baoan District has increased rapidly, and a number of well-known key enterprises at home and abroad have been established, mainly including Shenzhen Haohao Technology Development Co., Ltd. and Shenzhen Orende Optoelectronics Co., Ltd. The company, Shenzhen Yuwei Industrial Co., Ltd., Shenzhen Huabei Industrial Control Co., Ltd., Shenzhen Zhouming Technology Development Co., Ltd., Shenhualong Technology Industrial Co., Ltd., Shenzhen Bangbeier Electronics Co., Ltd., etc., these enterprises are the leaders of the industry. The main technical research and development level ranks in the forefront of the country, and some of them reach the international advanced level and have a certain industrial scale. The production content includes substrate materials, epitaxial wafers, chip design and manufacturing, packaging, high-brightness display, landscape lights and other various application products. And has a large-scale industrial chain.
Last year, Baoan District comprehensively promoted the circular economy development leading group office to conduct a comprehensive survey of the LED industry in the area under its jurisdiction to understand the current status of LED technology and industry in the region, and to collect sufficient materials for the formulation of industrial development plans. It is understood that in the future, Baoan District will vigorously help LED enterprises to rapidly expand their industrial scale, give full play to their technological advantages, actively carry out domestic and foreign technical cooperation, increase innovation capacity building, and strive to build Baoan District into a major domestic LED lighting industry. Ground.
It is used for continuous level measurement. The signal transmitted by its sensor is collected by the receiving system after being reflected by the target, and the distance of the target is determined by measuring the reflection running time. Then the level distance is converted into an output signal and output as a measured value.
The liquid level radar is applicable to the continuous non-contact liquid level measurement of liquid cargo tanks and overflow tanks of oil tankers and chemical carriers. It is also applicable to the liquid level monitoring of other oil tanks, towers, tank equipment and oil production platforms. Its measurement results are not affected by medium replacement, temperature change and gas or steam coverage.
