New breakthrough in water-cooled bulb technology

LED bulbs have always relied on traditional aluminum fins to solve the heat dissipation problem of LEDs, which has caused an inevitable problem. The bulbs that use aluminum fins dissipate heat less than 80 degrees, and the rest of the dark areas are aluminum fins. The film is obscured, so that the spherical light reflected by the bulb is killed. This kind of bulb is used for crystal lamps or other decorative lighting fixtures, which makes it difficult to realize its aesthetic value, plus many bulbs are used upwards. The installation method makes a large area dark area appear in the lower area where illumination is required, and the area under the illumination needs to be illuminated by the reflection of the wall body, and the utility is greatly reduced.

The aluminum fin heat dissipation adopts a channel type heat dissipation structure. In order to control the junction temperature of the LED chip , the heat conduction channel from the wafer to the surface of the aluminum fin must be opened, but the combination of various materials generates a lot of thermal resistance, so that The thermal conductivity of this channel is limited, and the cost of the heat conduction channel between these links must be increased, and the effect is not very good. Some bulbs use a form of light-emitting struts to achieve a stereoscopic light pattern, which in turn leads to a narrowing of the heat-conducting channel. Although the volume of the heat sink is further reduced, the light-emitting form of the light bulb achieves a stereoscopic light type, but its LED chip junction The temperature is very serious, the whole lamp decays very fast, which violates the practical value of LED energy saving and long life.

Technical characteristics of water-cooled bulbs

In order to realize the practical characteristics of high efficiency, long life and spherical light of LED bulbs, water-cooled lamps realize the application of LED bulbs by using the company's patented thermal conductive light-guiding liquid. The light guiding liquid is an insulator, and there is no problem of oxidation of the contact parts, and the refractive index and light transmittance of the liquid are excellent, which plays a key role in the light output of the LED and the improvement of the color rendering index. By using the inside of the lamp housing to fill the special liquid, the LED bulb can emit the same light type as the traditional incandescent lamp, and perfectly solve the heat dissipation problem of the LED light-emitting chip, so that the whole lamp has a longer life and truly realizes the LED ball. The light-shaped three-dimensional shape of the lamp, the appearance is beautiful, and the service life is long.

Ac Controller

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.
