The lighting industry has undergone major changes with the advent of LEDs. The popularity of LED lighting in Japan is expanding day by day, and South Korea is proposing to become the world's top three LED powerhouses in 2012. In the context of the government and enterprises to promote the LED industry, South Korea is stepping into the global LED power.
In Japan, Panasonic, Toshiba, Hitachi and NEC have developed LED products. South Korea is under the law of protecting small and medium-sized enterprises, and the lighting industry is mostly composed of small and medium-sized manufacturers. Representative manufacturers include Kumho Electric and Southern Song Dynasty bulbs. In addition, foreign companies such as Osram Optoelectronics of Germany, Philips Electronics of the Netherlands and General Electric of the United States are also actively developing the Korean market. Currently, the lighting industry in South Korea has successively invested in LEDs with the maturity of LED lighting.
It is understood that the South Korean lighting industry has long protected SMEs. However, as LED semiconductors become key components, large-scale companies such as Samsung Group and LG Group have invested in LED lighting. In addition, after 2010, including large-scale iron-making manufacturer Posco Group, and oil refining and communications giant SK Group And so on, all have stepped into the market.
In addition, South Korea’s venture companies have also been established. At present, there are more than 400 manufacturers of LED lighting in South Korea. In the next two to three years, these manufacturers will inevitably have market consolidation and elimination. Therefore, the South Korean government regards "low-carbon green energy" as a national development strategy and clearly publishes the measures taken by the government for low-carbon green growth. The key area is the LED industry. The strategy also determines the direction in which the South Korean government is actively using LED lighting.
The South Korean government expects the global market size of the country's LED industry to grow to $100 billion by 2015. In order to ensure a leading position in this huge market, South Korea has set a goal of increasing the market share of LEDs from 8.3% in 2008 to 15% in 2012, and has formulated relevant policies for the LED industry, such as creating market-leading policies. Demand, ensuring global core technology, and building a stable growth foundation. The South Korean government and manufacturers jointly promote the LED industry, making South Korea's LED strength a terrible behemoth in the future. In the face of the strong actions of the South Korean government, Taiwan’s indecisive ruling units may have to work harder.
42mm DC Brushless Gear Motor mainly including 42RPBL4250 and 42RPBL4260
Since spur gearbox or worm gearbox has a limited lifespan, and brushless motor can achieve more than 2000 continuous hours, so we merely use dc brushless motor with spur gearbox.
42RPBL4250 and 42RPBL4260 are both DC Planetary Gear Motor, the available gear ratio including: 3.7, 5, 13, 18, 25, 49, 67, 92, 125, 181, 246 etc
Brushless motors are typically 85-90% efficient whereas brushed DC motors are around 75-80% efficient. This difference in efficiency means that more of the total power used by the motor is being turned into rotational force and less is being lost as heat.
Brushless DC motors have many advantages over their brushed DC motor counter parts. The most obvious advantage of a brushless motor is its lack of brushes and physical commutator. This difference means that there are many fewer parts that can wear out or break and need to be replaced than in a brushed motor.
