used stage lighting for sale

Last year, China’s LED lighting industry output value of over 200 billion yuan, an increase of 32% over the previous year; product quality pass rate increased by 30%, the output and quality of double upgrade.
According to the China Quality Daily reported, LED lighting industry has become one of China’s most important emerging strategic industries. Two years ago, more than 2,600 more than the LED lighting business, employing more than 100 people, the scale of the industry has been ranked first in the country. However, due to LED lighting products,  used stage lighting for sale high-speed updates, product standards development cycle can not keep up with the pace of technological development on the one hand, a lack of standards and hysteresis phenomenon, while restricting the rapid spread of technological innovations, but also created the problem of product quality control; another On the one hand the development of standards revision process many links from drafting to publishing the implementation cycle is long, some indicators even in the face of standards promulgated situation that is out of date, the lack of scientific assessment based on the quality of LED products, disorderly market competition, product quality varies greatly, has seriously hampered the healthy development of the LED industry.

2012, China Quality Supervision Bureau to promote the standardized system of emerging industries, to enhance the competitiveness of the new round of industrial development, technical support to the National Institute of Standardization, the development of the emerging LED lighting industry standard system development planning and roadmap . used stage lighting for sale Roadmap for the industry characteristics, planning, formulation of standards revision and implementation steps proposed key technical standards in the next few years, the development of revised and Implementation Guide, an important guiding role and significance of the effective implementation of the strategic emerging industry technical standards planning.
The past two years, the China National Institute of Standardization according to the road map, the benchmark system planning and requirements, organization full of leading enterprises, research institutes, testing organizations, industry associations, a total of 134 units, from the semiconductor lighting technology and product research, development, production standardize enterprise; establish product quality evaluation system, the benchmark index as technology development soared to maintain standards and synchronization of the R & D technology to achieve the dynamic assessment of the quality of LED lamp technology, dynamic LED lighting products, LED used stage lighting for sale products the benchmark index The quality evaluation system covering all fields of the industry chain, prompting a decline in the cost of production of LED products, production and economic efficiency of enterprises has improved.

We use LED display alerts, occasionally encountered LED display black screen phenomenon, sometimes the screen is in use is normal, suddenly black, black sometimes appears in the sending program content, sometimes just turned on the electricity instantly black black state occurs, but in the process control system uses the same kind of phenomenon may be caused by a variety of reasons, even the LED display black also due to different operating or different environments. Encountered this phenomenon please do not worry, we can refer to the following aspects to determine the “fault” and the exclusion.

Make sure to have all the right power control system, including all hardware. Also, note that the positive and negative terminals of the power supply if there is reversed, then the wrong stage lighting usa. (+5 V is positive, GND is the negative.);
2 If you are using a wired control card, check and repeatedly confirmed the serial cable is used to connect the controller loose or peeling. (If the release of information on the way black is likely to be caused because of this reason, in the communication process is interrupted communication lines loose,

Hence the screen black. Do not think the display body did not move, it is impossible to loose line, hands-check, which is very important that you want to solve the problem quickly. );
If you are using Ling Guan GPRS wireless control card, on his way to publish information black, need to re-query whether the control card online, online re-released program information after the success of the screen to light (due to GPRS control card performed Ads

The stage lighting usa action is off-screen to open the screen action, if you publish unsuccessful, then it send instant off-screen, you can not start the opening screen action, which led LED display black screen);
4 If you are using Ling Guan wireless the GPRS control card, LED display found in the use sudden black screen is not lit, the operating software to query the clock, and then proofread the clock, LED display to light up work;
5 If you are using LED control card is the motherboard HUB board, please check and confirm whether the LED stage lighting usa display and connected to the main control card HUB distribution board tight junctions, is inserted backwards. Please check and confirm connecting Ling consistent control cable between the card and HUB distribution board Loose or inserted upside phenomenon.
