In recent years, with the gradual maturity of LED product technology and the gradual decline of product prices, LED products have begun to be widely used in project engineering, such as Beijing Aquarium, China National Museum, Guangzhou Asian Games, etc., LED lighting applications have exploded development of. According to statistics, by 2010, the proportion of LED products using all lighting has exceeded 56%. Zhou Yanwu, research director of Shuiqing Muhua, who has long tracked the LED lighting industry, said that LED applications are divided into three categories, one is general lighting, the other is LEDs on mobile phones and TVs, and one is the lowest category, namely advertising. Cards, etc. Domestic companies are basically in the last category. It is understood that the technical threshold of LED general lighting is very high, only five companies in the world can do it, and they are concentrated in the United States and Japan, and the gap between South Korea and Taiwan is very wide. However, it is reported that LED is still dominated by backlighting applications. DisplaySearch's predictions for the LED market point out that the demand for lighting LEDs is based on the number of LEDs that have been forced to backlight LEDs, and will exceed the backlight LED. DisplaySearchTaiwan LED senior analyst LeoLiu said in 2014, in terms of LED demand in 2011, The number of lighting LEDs was 13.29 billion, and the number of backlight LEDs was 45.69 billion. The difference between the two is about 3.4 times. In 2014, the demand for lighting LEDs and backlight LEDs will reach 58.58 billion and 10.063 billion, respectively, and the LED market demand for lighting will officially surpass backlight LEDs. It is understood that the demand for lighting LEDs exceeds that of backlight LEDs, mainly due to the gradual popularization of LED lighting, and the reduction in the number of LEDs used in the backlight panel of each liquid crystal panel device. LCD TVs and LCD monitors that use large-size LCD panels are currently the driving force behind the backlight LED market. Due to factors such as increased brightness of LEDs and lower product costs, the number of LEDs in these products will be less and less. In devices using large-size LCD panels, LED backlights are now in the mainstream stage. Therefore, even if the number of LEDs used in each product is reduced, the number of products is still increasing, so the demand for LEDs in the entire market continues to expand. However, after the LED backlight is popularized to a certain extent, it is difficult to rely on the increase in the number of products to compensate for the decline in LED backlight usage, so the demand for LEDs will gradually slow down. DisplaySearch predicts that the demand for backlight LEDs will reach its peak in 2013 and then gradually decrease. DisplaySearch believes that the popularity of LED lighting will continue for some time, so demand will continue to increase. It is understood that in 2011 LED lighting products accounted for only 1.9% of all lighting. Even in 2014, the demand for lighting LEDs surpassed that of backlight LEDs, but its proportion only accounts for 9.3% of the lighting market, so the future growth space is still very large. LED General Lighting The most technologically advanced and monopolized in the world is the US CREE . Chinese LED companies can only buy LED particles for assembly. Zhou Yanwu also analyzed that the low-end industries that domestic LED companies are good at, there has been a serious overcapacity situation, and the performance of listed companies is bound to be affected. According to insiders, domestic LED companies are small in scale and backward in technology. Local governments have made huge financial subsidies in order to vigorously develop their industries. And if they leave the government, the financial data of these listed companies will be very ugly. Wireless Access Point (AP) is a new type of wireless network device, it is a network device based on Wi-Fi technology, can convert a wired network into a wireless network, so that you can easily access the network at home, office or public places. The feature of wireless ceilinged AP is that it uses ceilinged design, can be suspended on the wall top or ceiling, and can transmit the signal to a wider range, so that users can have more space in the same building.

At the "2011 leds conference" in San Diego, Calif., Jim Brodrick, director of the US Department of Energy's (DOE) lighting program, said LEDs are used in recessed downlights, outdoor area lighting, 2x2 feet of dark lighting and The performance of frozen lighting is perfect, but the performance of LEDs in small retrofit lamps with only one bulb, straight-line replacement lamps and recessed circular ceiling lighting is not ideal. but. The linear 4-foot LED tube has been gradually improved, approaching the efficiency of fluorescent lamps, but the light output and distribution of directional LEDs are still not as divergent as the fluorescent lamps.
Second, the advantages of wireless ceiling AP
1, the advantage of wireless ceiling AP is that it can better meet the requirements of various environments, can better meet the requirements of indoor space, can better meet the requirements of outdoor space, and can better meet the multi-level coverage area.
2, wireless ceiling AP can better meet the requirements of more network users, because it can better support multiple users, and can meet the connection of a variety of network devices, such as can support the connection of computers, smart phones, tablets and other devices.
3, wireless ceiling AP can better meet a variety of network security needs, because it can provide a variety of network security functions, including encrypted transmission, network isolation, access control, content filtering, authentication and other functions, can better protect network security.
Third, the application of wireless ceiling AP
Wireless ceiling AP can be widely used in homes, offices, companies, schools, hotels, restaurants, public places and other places to meet the network needs of different places.
1, Family: Wireless ceiling AP can better meet the network needs of the family, can make the family network coverage larger, family members can more convenient access to the network at home, more secure access to the network.
2, office: Wireless ceiling AP can meet the network needs of the office, can better meet the network needs of multiple users inside the office, can better meet the network needs of multiple users outside the office, can better support the office security network needs.
3, the company: wireless ceiling AP can better meet the company's network needs, can better meet the company's internal network needs of multiple users, can better support the company's security network needs, can better meet the company's external user network needs.
Fourth, the use of wireless ceiling AP
The installation of wireless ceiling AP is very simple, only need to install it on the wall top or ceiling, and then connect it to the network interface, and finally use its configuration software to complete the installation and setup, the use of wireless ceiling AP is very convenient, as long as the network function is enabled, you can allow multiple users to easily access the network in the same building.
