Outdoor LED display how to do waterproofing measures

In the typhoon is approaching, the rain increased, then the need to pay attention to outdoor waterproof led display problems, enhance the waterproof protection to extend the life of the display, so the need to protect the source from the water gatekeeper. The choice of waterproof connector is particularly important, there are many varieties of waterproof connectors on the market, but the quality varies, then how to choose?

First, in line with the relevant electrical, installation, connection, insulation, protection and other technical standards, which is the basis of choice.

Second, look at the size of the assembly tolerance control accuracy.

Because the connector is often related to the connection, waterproof, male and female contact with the need for high precision dimensions, high-end and low-end connector at first glance almost appearance, structure, etc. are not as high or low, but How do you take the time to carefully measure with the caliper multi-pair connector with the size will find that poor quality with the size of a great change, that is, the stability of the connection is not guaranteed, the consistency of batch products is poor.

Third, led display manufacturers can not just look at the standard, should go beyond the standard, pay attention to the practical application of the situation encountered.

Because the LED industry connector design and production of some of the selected standard is actually borrowed from other industries, because the industry application time is relatively short, many articles do not meet and meet the rapid changes in the LED industry requirements, such as anti-aging materials Assessment, but generally said that in line with outdoor engineering use, but how to define, is to see UL yellow card or to the test subject, the use of outdoor life is based on the project manufacturer's commercial contract or subject to a we can recognize the "technical use Life ", which directly affect the product selection and design of materials, led connector material is also caused by a wide variety of reasons.

    In addition, the requirements of individual standard terms is still relatively low, that is the quality threshold is very low, resulting in a variety of family workshops are free to produce, some test standards are in the "standard static environment" under test, often After the engineering accidents, to test the connector to find the standard or qualified, and why, because the laboratory tests have chosen the standard terms and conditions of the standard environment, and application site environment vary widely, such as the connector tail M16 cable head Cable gripping and anti-torque requirements, the standard only said tensile strength of 80N, anti-torque value is greater than 0.45Nm but the connector in the actual use of artificial strong pull and twist around, so that the actual data may be far about the standard value, And this force to maintain long-term between the two connectors, after a long period of outdoor use, often resulting in the connector is not waterproof or poor contact and open circuit.

Fourth, led display manufacturers to pay attention to look at the structure of the principle of design, structural design is very important.

If the waterproof, connection and other principles of the design of more advanced, it has been one-upmanship, and if the choice of outdated structural design principles, even in the manufacturing process quality control is good, but often in reliability, outdoor long-term weathering Sex, etc. are not as innovative products more reliable.

Fifth, look at the production of led display connector manufacturers quality control system.

Connector companies do a pair of connectors to provide the test is easy, you can get a good test scores, but to the factory you will find that there is no test of raw materials, finished products do not have to test the link, repair and testing of nonconforming products No procedures, etc., have affected the quality of the product packaged, that is only 100% qualified, not thousands of thousand, ten thousand of qualified. In the long run, good quality control and even lighting manufacturers choose connector manufacturers the most important reference factor, otherwise it will "lose big." Overall, with a larger scale of production, technical testing equipment, business, product quality control and stability of a corresponding higher grade.

    Choose a good outdoor LED display, need to consider from all sides, not only the quality of the product, but also according to the company's overall strength and quality system, after-sales service, and so these considerations. Lianchenfa takes the quality of products as the life of the enterprise, from raw material procurement to production, installation and testing. Every step is carried out in accordance with ISO9001: 2008 international quality control process, scientific management and excellence. Products have passed UL, RoHS and CCC of professional organizations. , CE, EMC, FCC, ETL, IP65 dust and water testing and other quality certification to ensure that every factory products are high-quality, the basic lead and achieve in the industry LED products standardization, batch production management system of high standards. At home and abroad to win a good performance reputation in the industry have a profound impact.
