          Domestic LED product quality problems frequently improve quality is imminent

          China's LED industry is developing rapidly, and product promotion is also inevitable, but in the process of development, it is inevitable to encounter problems, and the quality of LED products is increasingly valued by consumers.

          Recently, Health Canada and Pier 1 Imports, Inc. jointly announced a voluntary recall of indoor/outdoor wall-mounted decorative lighting made in China.

          On January 16, the Guangdong Provincial Quality Supervision Bureau released the results of the special supervision and inspection of the quality of LED street lights and light source controllers in Guangdong Province in 2012. The results showed that in batches of 51 batches of LED street lights and light source controllers, 20 batches were found. Unqualified, the rate of unqualified products was 39.2%. In addition, among the notified non-qualified companies and product lists, a number of companies were included in the catalogue of a€?Green Lighting Demonstration City Street Lamps Recommended Productsa€?.

          Some time ago, Lehman Optoelectronics fell into a quality dispute, and its four customers took joint advocacy actions after the communication failed.

          Since there is no unified standard and specification for LED products in China, LED manufacturers can easily reduce the cost of products to reduce costs. Enterprises can also choose to maintain the price to increase profits, or lower the price to occupy the market, thus providing enterprises with more Diversified "development."

          In the LED lighting market, consumers generally do not have the relevant professional knowledge, and rarely use product parameters to select good quality products. Therefore, when purchasing LED products, the price becomes an important factor affecting consumers. Under such circumstances, occupying the consumer market is as simple as price reduction.

          At the same time, in the face of the ever-expanding market, enterprises urgently need to occupy their own a€?territorya€? to ensure that they will maintain the market in the future competition. For LED companies, it is especially important to use price reduction to occupy their own market. . As for how to reduce the cost of the product to ensure the profit of the company, a large part is to sacrifice product quality.

          The above factors are mixed together, which leads to the chaos of the LED market, the quality of the products is uneven, and many merchants cut corners in order to increase profits, which directly leads to the decline in the quality of LED products.

          It is undeniable that with the development of technology and the improvement of the level of science and technology, the quality of China's LED products has improved, and began to develop towards the international level. However, because China's relevant standards and norms are still not perfect, there are also many problems in the development process.

          Whether it is the domestic market or international competition, China's LED products are inseparable from the quality assurance. Whether it is from the development of the industry or from the long-term perspective of the company, it is necessary to improve the quality of LED products. LED review companies should take a long-term view and focus on the development of the international market and the development of the entire industry in the future.

          The development of the LED industry requires all LED companies to work together to improve the quality of the products together. Only in this way can the LED industry be completed and the LED industry in China will develop better and better.

          The aviation earphones are mostly disposable, so the structure is extremely simple, the shape is relatively ordinary, the materials are small, and the annual usage is very large. The number of inquiry can reach several million or even tens of millions, so the cost is very cheap. earphones can cost as little as 10-15 cents. Therefore, they are disposed of as garbage after used, and passengers could take it away for personal use.


          Styles can be divided into on ear headphones and in ear earphones.


          Functional difference: power, impedance, and sensitivity etc. are also different. Airplane Headphone is mainly customized according to the equipment, place and user used. For example, 1 customer might  require 300 ohms impedances , and other customers may need 32 ohms. For adults, the sensitivity may reach 100DB or more.To children, the sensitivity may be around 85-90 DB.


          In addition, aviation headphones are not all disposable ones. Some first-class cabins need to be equipped with headphones with good noise reduction, sound quality and functions. So the price will be much more expensive.
