A new round of LED lighting supply chain transformation

In the past three years, China's LED industry has grown at an average annual rate of 31%. In the next three years, the average annual growth rate is 23%, and the growth rate has been falling. One of the main reasons is that when the acceptance of LEDs is very high, it means that the quality is more mature and the replacement rate is higher. At the same time, it also faces a longer product replacement cycle.

Dr. Zhang Xiaofei, Chairman of Gaogong LED

Zhang Xiaofei, chairman of Gaogong LED, mentioned in the 2015 high-tech LED supply chain good product tour Hangzhou station meeting that the LED industry growth rate will slow down in the next three years, but the annual chip industry growth exceeded expectations, the reason is the light effect The level is increased, the number of dicing chips in the same area is increased; the second is that the utilization rate of PSS substrate of blue-green optical chip is increased from 70% to over 90%; the third is the rapid increase of MOCVD total operating rate and total capacity utilization; The acceptance of chip customers has increased, domestic chips have replaced imports, and domestic chip market demand has grown rapidly.

In just a few months after entering 2015, the number of packaging companies has decreased from 1,600 in 2014 to 1,300. Following the principle of “big and big Evergrande”, the proportion of expansion of the large and medium-sized packaging enterprises of over 100 million yuan accounted for more than 60%, and the market competition pressure was even greater. The survival environment of small and medium-sized enterprises was worrying.

In the downstream application industry, indoor lighting continues to grow at a high speed, which is still the main driving force for the rapid development of the industry, and the market share has increased to 39%.

Faced with a new round of changes in the industry, companies are looking for the right direction. The upstream market share is more and more concentrated, small and medium chip manufacturers are in jeopardy, so the choice of chips should be noted; large-scale mid-stream enterprises are expanding production, most small and medium-sized enterprises are stagnant, and the future is worrying. It is better to find a way out earlier, merge or avoid the low end. Large-scale enterprises; downstream enterprises face reshuffle, traditional lighting enterprises re-position, small and medium-sized enterprises can choose professional focus.

600V DC Electronic Load

600v DC Electronic Load can be switched quickly between different values in the same operating mode, including CC dynamic mode, CV dynamic mode, CR dynamic mode and CP dynamic mode, CC/CR high speed dynamic mode up to 50kHz. This function is suitable for transient test of power supply, test of battery protection characteristic and battery pulse charging etc. Dynamic mode test has continuous mode, pulse mode and toggle mode.

Additionally , programmable DC electronic load can also have 200V DC Electronic Load and 1200V DC Electronic Load for more options.
