Talking about the problem of UVLED curing light source standard

Click:[1547] Publish Time:2019-10-22

    UVLED curing light source system refers to the use of uvled light source lamp beads as the curing light source. 

The heat sink and electronic control device are the necessary conditions for stable operation of the uvled light source.

Therefore, the system is usually called uvled solidified light source system. In recent years, UVLED curing technology 

has basically matured in China. UVLED curing develops rapidly, and the experience of integrated UVLED curing light source

development at home and abroad, we can consider the UVLED curing light source standard from the following three points.

1. the establishment of a standard system.

   We should give full play to the synergy role of management, research, and research, give full play to the advantages of 

all links in the industrial chain, and mobilize multiple superior units to coordinate and tackle problems in the form of 

project tasks, fully discuss and experiment, and fully draw on relevant international standards to establish suitable 

development characteristics for China's industry. Standard system. Standard setting is to protect the industry, and it 

cannot be the threshold set by some enterprises for commercial interests.


2. standards should be based on relatively mature products or technologies.

   Some technologies and products have not yet been fully finalized, and rushing to standardize limits future product 

development and technology development. Therefore, it is possible to consider the introduction of basic norms and standards

such as terminology and test methods in order to regulate the market and end the disorderly competition.


3.The standard system includes national standards, local standards, and enterprise standards.

   The three are mutually reinforcing, and the continuous introduction of local standards has laid a good foundation for the

establishment of national standards. Enterprise standards and local standards are important components of the national standards 

system, such as enterprise standards, and specific standards for the company's characteristic products are specific refinements

and manifestations of national and local standards. Therefore, the formulation of enterprises and local standards should be More

detailed, corporate standards should generally be higher than national standards.


4. after the introduction of standards, especially after the introduction of mandatory standards, the market supervision department 

    should quickly establish a system of supervision, access, certification, testing, etc., and strengthen the promotion and 

implementation of standards.
