According to the world automobile production statistics released by the World Automobile Manufacturers Association, the total world automobile production in 2009 was 60.99 million. Among them, China rose to the world's largest automobile producing country, with annual output increasing by 48.3% year-on-year, leading to 13.79 million units. It is estimated that China's automobile production and sales will exceed 15 million in 2010 and hit a record high.
The High-Tech LED Industry Research Institute (GLII) predicts that with the continued growth of Asia, especially the Chinese automotive market, and the maturity and cost reduction of LED backlighting and lighting applications, the global automotive LED market will be 15% per year from 2010 to 2012. The speed of expansion will increase its market size in 2012 from $4.11 billion in 2006 to $12 billion. The annual sales of automotive LEDs will be doubled in the next 10 years. At present, LED has been widely used in automotive interior lighting. LEDs are gradually transitioning to automotive headlights, taillights and other products, showing a trend from the inside to the outside and from the back to the front. In recent years, with the improvement of the level of some automotive lighting technology and the cost reduction, the number of LED applications has increased. Domestic Honda Accord, Nissan Teana, Crown, Reiz, Cadillac series, Buick Rongyu and other models have adopted LED lighting technology.
In terms of applications, the backlights for 5-10 inch LCD panels used in future car dashboards, portable DVD drives and car navigation systems, and the white LEDs used in automotive headlights will be the driving force for this market. Although the growth rate of the automotive LED market is slow in 2009, the current day-to-day lighting regulations promoted by the EU will further drive the take-off of the automotive LED market, and continue to expand from the original automotive brake lights, direction lights, and vehicle room lighting.
Taking the car headlight LED as an example, the "Lexus LS600h", which was launched by the Japanese car manufacturer TOYOTA in May 2007, is the world's first model equipped with LED headlights. In the same autumn, the German Audi R8 was also equipped with LED lights. The LS600h uses white LEDs only for low beam headlights, while the R8 and Cadillac Escalade Platinum's low beam headlights and high beam headlights use white LEDs. Among them, LS600h's headlight supplier is Nichia, R8 is US Philips Lumileds Lighting, and Cadillac Escalade Platinum headlight supplier is Germany Osram.
The global white LED market research report released by Fuji Chimera Research Institute of Japan is expected to reach 350.2 billion yen (about 28 billion yuan) in 2010 and an annual output of 15.68 billion 7820. Among them, although the vehicle use accounted for a small proportion of the entire market, it is expected to achieve significant growth in the future. The white LED market is currently mainly used for liquid crystal backlights. The vehicle use is centered on the interior lights of automobiles, and the number of shares is only 5 to 6%. However, it is expected that the headlamp restrictions will be relaxed, coupled with the increase in the brightness of white LEDs. By 2010, there will be a significant increase in the number and amount of white LEDs used in automobiles.
The LED LED market has a high growth rate, and the current average gross profit margin is generally above 20%, which is an area in which LED manufacturers compete. However, the Industrial Technology Research Institute of Taiwan pointed out that due to the high requirements for the headlights of the car headlights in terms of heat dissipation, reliability, brightness, etc., the manufacturers that have been introduced by the car manufacturers are still dominated by international companies such as Nichias and Osram, and LED factories in Taiwan. At present, the main market is mainly based on the application of automobile taillights and interior lights such as instrument panel backlights. Including Yiguang is the main supplier of DaYi, the small car supplied by Dongbei to Nissan, and Hongqi is also the OEM of the instrument panel backlight LED manufacturer.
In terms of taillights and in-vehicle application lights (such as instrument panel backlights), there are already many LED factories in Taiwan, including Hongqi, which has long been a foundry of instrument panel backlight LED manufacturers. Dongbei is currently Nissan. The taillight supplier of the March model, Yiguang is the major supplier of DaYi. In terms of total shipment amount and quantity, Yiguang is currently a large-scale manufacturer of automotive LEDs in Taiwan, but this part of the total revenue share of Yiguang is still very low.
According to data released by the National Semiconductor Lighting Engineering Research and Development and Industry Alliance (CSA), Dominant and OSRAM currently account for 60% of the global market share of automotive electronics. In recent years, China's Taiwan and the domestic Pearl River Delta and the Yangtze River Delta region have developed rapidly. In the past two years, the quality has also improved significantly, and they have won a certain market at a low price. Among them, Shenzhen Ruifeng Optoelectronics is the mainstream supplier of optoelectronic devices for domestic brand auto manufacturers in small and medium-sized LCD backlights for automotive instrumentation, car audio, car DVD, etc. The technical level and market share of products are second only to those in China. Osram, Germany. Ruifeng is at the domestic leading level in the development of high temperature resistant materials for automotive applications, phosphor color matching technology, and vibration resistance of products.
With the improvement of the technical level of LED lighting components and the decline of product prices, LED combination taillights, LED brake lights, LED turn signals, etc. will become the mainstream configuration of China's car lights. CSA expects that China's LED front-loading market (OEM supporting market) in 2010, LED combination taillights, LED central high-position brake lights, automotive instrument backlights and other LED lights will reach 5 billion yuan.
The WiFi 6 Ceiling Wireless AP is a ceiling wireless access point based on the WiFi 6 (802.11ax) standard. It is a device designed to provide wireless Internet connectivity and can be mounted on the ceiling of a building to provide users with high-speed, stable wireless Internet coverage.
WiFi 6 Ceiling Wireless AP offers a number of advantages over previous WiFi standards such as WiFi 5, or 802.11ac. The benefits of WiFi 6 Ceiling Wireless aps and how they affect users are described in detail below.
1. Higher speed and capacity:
WiFi 6 Ceiling Wireless AP uses OFDMA technology (orthogonal frequency division multiple access), which can divide the wireless channel into multiple sub-channels, each sub-channel can transmit multiple data streams at the same time, improving the capacity and efficiency of the network. This means that the WiFi 6 Ceiling Wireless AP can deliver higher speeds and more stable connections to more devices at the same time with the same spectrum resources. For high-density environments, such as office buildings, conference rooms, or large event venues, WiFi 6 Ceiling Wireless AP can better meet users' needs for high-speed networks.
