[Text / high-tech LED Gan Qin] In 2015, the domestic LED indoor lighting output value still maintained a high-speed growth trend. As one of the wide range of indoor lighting products, LED downlights have become the focus of users, and their market share has also been greatly improved.
According to the survey data of the High-tech Research Institute LED Research Institute (GGII), the total output value of indoor lighting in 2015 reached 135.3 billion yuan, a year-on-year increase of 25%. The output value of LED downlight products reached 18.53 billion yuan, an increase of 30.8% over the same period last year. .

Recently, the 2015 Golden Globe Awards Ceremony was successfully concluded. In the final selection of the LED Downlight Awards, Xinli Light Source won the Golden Globe Award. This is the new light source that won the award after winning the award last year. The repeated awards are enough to prove the leading position of Xinli Light Source in the field of LED downlights. Jiamei Times Lighting and Mulinsen were also shortlisted for the award.
For the award-winning LED downlight products, Zhao Kun, vice president of Xinli Light Source, said that the product is prepared by adopting a phosphor device scheme by discarding the traditional dispensing method, and the fifth-order Bin rate of the light source can exceed 90%. The product also integrates light, machine, electricity and heat into one, reduces the module volume and reduces the cost, and effectively solves the problem of heat dissipation and life caused by the driving power supply.
It is understood that downlights are generally used in shopping malls, offices, factories, hospitals, home improvement and other fields. With their advantages of small heat generation, long life, energy saving and environmental protection, and low maintenance costs, they have a customer base that cannot be ignored.
At present, LED spotlights are relatively stable in engineering use, and are rarely used in distribution channels. In addition to some private villa decoration, the retail users generally choose to use bulbs or tubes instead of downlights.
When the downlight is used for home lighting, the requirements for the product are diversified, and the appearance and function of the product are also required. When used for engineering lighting, the focus is on the product quality, including the heat dissipation index. Requirements, coupled with a large amount of engineering lighting, also put forward higher requirements for cost performance.
Zhao Kun said that the main contradiction in the current LED lighting industry is the contradiction between the increasingly lower product price and product quality assurance, and LED lighting products will certainly develop towards modularization.
In order to solve the current diversity and flexibility of LED light sources, the resulting diversification of LED application process, the contradiction between individualized demand and large-scale manufacturing, the LED downlight product of Xinli Light Source adopts modular design and standardized interface. Versatility, interchangeability, and standardization provide a broad design space for downstream applications, which is easy to maintain and replace, and more cost-effective.
All along, Xinli Light Source is committed to the development of high reliability, high light quality, cost-effective products, with high-quality innovative products in the market shine. Zhao Kun believes that in the future, with the gradual stabilization of quality and the continuous reduction of prices, LED downlight products will certainly show greater advantages in the field of indoor lighting.
What is a wireless AC controller? What does it do?
Wireless AC controller is a kind of network device, such as the AC100/150 of Fengrunda, which can be used to centrally control and manage wireless aps. It is the core of a wireless network and is responsible for managing all wireless aps in the wireless network. AP management includes: delivering configuration, modifying related configuration parameters, RF intelligent management, and access security control.
Why use a wireless controller, and what exactly does it do?
In fact, the role of the wireless controller is to play a gateway function between the WLAN and the Internet (on the router), and the data from different access points are aggregated and accessed to the Internet. The role of an access point (AP) is to complete wireless access, and it can control user access through network flags.
The role of wireless controllers
1, Flexible networking mode and excellent scalability
The AP does not need to be directly connected to the AC, so that the AP can be deployed in any place that needs to be covered through the network, such as you deploy an AP in each employee's home, and then connect to the wireless controller inside the enterprise through the VPN, you can expand the wireless network of the enterprise to the family of each enterprise member.
2, intelligent RF management functions, automatic deployment and fault recovery
Through the dedicated RF management module, we can initially estimate the AP deployment according to the user's architectural design drawing, and can calculate the average bandwidth of the wireless terminal, the coverage between AP and AP in the actual debugging process.
3. Centralized network management
All the configuration of the wireless network can be completed by configuring the wireless controller. For example, enable, manage, and maintain all AP devices and mobile terminals, including all functions such as radio wave spectrum, wireless security, access authentication, mobile roaming, and access users.
4, powerful roaming function support
The wireless controller uses AP as the boundary combined with fast RF management system, which greatly reduces the connection time between wireless client and AP, and thus realizes the function of fast roaming.
5. Load balancing
AP and wireless controller systems can distribute wireless users or terminals to nearby aps within the coverage area of an AP, ensuring the number of each wireless terminal or the sum of AP bandwidth transmission or the upper limit of each wireless terminal bandwidth.
6, wireless terminal positioning, rapid fault location and intrusion detection
Wireless controllers can track and locate the location of wireless terminals, such as wirelessly connected computers, PDAs and Wi-Fi mobile phones.
7, powerful access and security policy control
At present, the wireless system supports authentication of 802.1, WEB authentication, MAC, SSID, VPN, etc., and supports various encryption modes such as WEP, WPA, WPA-PSK, WPA2, etc., and all configurations can be configured globally through the wireless controller.
8, Qos support
AP and wireless switching systems can limit the maximum bandwidth of a user's wireless connection within each user's privileges. For different IP services, the system can also define different QoS queues through the wireless switch module. For example, for wireless voice applications, SIP and RTP protocols can be set in the high queue, while common applications such as http and ftp can be set in the low queue.
The wireless controller AC is more advanced than the AP, plays the role of manager in the wireless network, and the wireless controller AC also acts as a client to complete a series of functions in the wired network (such as authentication, authentication, etc.). However, wireless controller AC is not a WLAN device specified in the 802.11 protocol family, but as a supplement to the protocol in specific applications, and its price far exceeds that of ordinary access point (AP) devices.
In small-scale wireless networks that use only a few aps, it is not economical to use expensive wireless controller AC equipment. However, if the number of wireless aps is large, more than 20 can be used AC controller.
