Looking forward to 2012, due to the fact that the huge production capacity of MOCVD machines is still not fully released, the oversupply of the entire industry is still difficult to resolve. However, manufacturers with patent thresholds and high technology still have the opportunity to tide over difficulties in this difficult situation.
Supply side - to adjust inventory and reduce costs as a matter of urgency In the recent end market demand is affected by the global recession, many LED manufacturers' export orders have fallen sharply. At present, there are still only a few orders for commercial lighting and public sector projects. According to LEDinside's observation, many small and medium sized LED manufacturers have been faced with the crisis of closing down before the Lunar New Year due to the decrease in export orders and the increasingly fierce competitive environment. It also made the upstream manufacturers more cautious in selecting customers and the amount of credit.
With cautious shipments and inventory levels rising steadily, most manufacturers have chosen to reduce capacity utilization and forced employee vacations to control costs and reduce output, but how to reduce the huge inventory level is a top priority for various LED manufacturers. .
Demand surface - LCD TV with LED backlight market waiting for terminal application demand emerged As for the consumption of a large number of LCD TV backlight market, in 2011 by the impact of the global economic downturn, the global LED-backlit LCD TV (LEDTV) shipments significantly lower than expected. In 2011, the total shipments of LCD TVs were also lowered from 220 million units to 203 million units.
However, with the 2012 World Cup soccer event in Brazil and TV brand manufacturers launching low-priced LED-backlit TVs to stimulate demand, it is expected that the sales volume of LCD TVs in emerging markets is expected to increase. The backlight market will help.
The demand side - LED lighting market grows slowly, multinational governments and manufacturers actively promote the LED lighting market, the traditional commercial space lighting market in Europe and the United States mature market as the largest, but after the European debt crisis, the European market growth momentum relatively slow. However, projects from the public sector or power plants show signs of growth. In particular, the number and scale of outdoor LED lighting and architectural lighting projects in the United States, Australia, and other markets have continued to increase. The LED streetlight plans and projects in the eastern United States have clearly grown, and Australia has also gradually formed the street lamp signs released by power plants.
High-power electronic power devices are repotted into an integrated module according to a certain combination of functions.
A power semiconductor module is a combination of certain functions and modes, and a power semiconductor module is a high-power electronic power device that is re-potted into a whole according to a certain function combination. Power semiconductor modules can achieve different functions according to the different components in the package. Power semiconductor modules can be used as air-cooled modules with air-cooled heat dissipation, and water-cooled modules with water-cooled heat dissipation.
It is characterized by simple installation, convenient use and maintenance, small size and light weight.
Typical applications in AC/DC motor control, various rectifier power supplies, industrial heating control, dimming, non-contact switches, electric welding machines, motor soft start, reactive power compensation, frequency converters, UPS power supplies, battery charging and discharging, etc.
