Gold-cool competitive Advantage of Industry through Technological Innovation and Cost Control

      Human beings have experienced hundreds of years since entering the era of electrical lighting. Under the promotion of technological development, the lighting industry has mainly experienced four stages of development. The representative lighting products in each stage have their advantages and disadvantages, but the lighting industry as a whole is developing in the direction of environmental protection and energy saving.

       Among all kinds of lighting products, incandescent lamps have a long history and a wide range of applications. However, due to their low energy conversion efficiency (i.e. light efficiency) through material radiation, countries around the world have gradually defined the schedule for the elimination of incandescent lamps. Among them, the phase out plans of Europe, Australia, Japan, the United States and other countries started relatively early. China officially released the phase out plan of incandescent lamps on November 4, 2011, and plans to completely ban the import and sale of incandescent lamps by 2016.

       In addition to the incandescent lamp elimination policy, China has issued a series of industrial policies since 2008 to support the energy-saving lighting industry, among which the promotion plan of LED lighting product financial subsidies in 2012 has promoted the growth of public and commercial lighting market. The semiconductor lighting energy saving industry plan issued in February 2013 has played a leading role in the development of led enterprises. Through financial support, enterprises can make breakthroughs in technology, make enterprises more confident in facing market competition and accelerate the internationalization process of China's LED industry.

       LED industry has experienced the market recovery in 2016 and the boom in supply and demand in 2017. In 2018, under the background of internal worries and external difficulties, the overall growth rate slowed down and entered the decline cycle. The annual growth rate is about 12.8% (12.5 percentage points lower than that in 2017), while the total industrial output value is about 737.4 billion yuan. Among them, the scale of upstream epitaxial chip is about 24 billion yuan, accounting for 3.26% of the scale of LED lighting industry, the scale of midstream package is 105.4 billion yuan, accounting for 14.29%, and the scale of downstream application is 608 billion yuan, accounting for 82.45%.

      Data shows that in 2018, China sold about 6.4 billion LED lighting products (sets / set), an increase of 36% year on year. At the same time, the in use of domestic LED lighting products has reached 6.4 billion (sets), and the in use penetration rate of domestic LED products has reached 49%. The market penetration rate has increased by 5 percentage points to 70% compared with 2017.

      China's semiconductor lighting industry technology has steadily improved. In 2017, the industrialized light efficiency of power type white LED reached 180LM / W, basically equal to the international advanced level; among them, the light efficiency of LED outdoor lamps exceeded 120lm / W, and that of indoor lamps exceeded 100lm / W.

       In the era of traditional lighting, product design and manufacturing process play a key role in ensuring the stability and durability of light sources. Lighting giants have the advantages of product quality by technology accumulation, which precipitates the brand strength and channel advantage, occupying most of the market.

       At present, the traditional lighting market is transforming to LED lighting, and the lower reaches of the industrial chain, namely, the light source manufacturing technology content and manufacturing cost, make the competitive advantage of Chinese local enterprises prominent, and European and American large enterprises have withdrawn from the general lighting business in China. On the other hand, with the support of the government and the emergence of M & A, China has gradually followed up in technology. From chips, packaging to light sources, the whole LED industry chain has been formed in China and developed rapidly. In the future, China's LED lighting industry will continue to develop in the direction of industrial integration and optimization.

       Dongguan Gold-cool nano technology has developed targeted products for LED market, which not only has good thermal conductivity, but also gives other properties of materials convenient for customers to use.

     GC-TG series thermal conductive silicone grease has the characteristics of fine paste, low thermal resistance and high thermal conductivity.

     GC-3k / 10K / 19K series is a kind of acrylic (acrylic) heat-conducting double-sided adhesive with good heat-conducting performance, reaching 0.8w/m.k-1.0w/m.k, which has good retention force and is widely used for bonding between PCB / FPC board and heat sink.

     GC-TP series thermal conductive silica gel sheet can solve the problem of contact thermal resistance well, at the same time, different structures are designed for different use scenarios: glass fiber cloth or silica gel cloth is added as the reinforcement carrier, with high strength, and in order to meet the requirements of fastening, it can also be designed as single-sided adhesive, double-sided adhesive to meet the fastening requirements between PCB and heat dissipation substrate.

      GC-GN series heat conducting mud is an indefinite heat conducting product with good heat conductivity and weather resistance. It is suitable for heat dissipation with complex structure, and it can also solve the noise problem of dimming series products.

     GC-ST series products provide the possibility for the heat dissipation of LED lamp head, making it possible for high-power products to be used in Small kits. This product successfully solves the problems related to lamp head insulation, heat dissipation and automatic production, especially in cooperation with gc-gn products, with obvious effect.

     Therefore, in addition to changing the design of LED, it is also necessary to select appropriate thermal interface materials, improve heat transfer and improve heat transfer efficiency..
