which means of communication should intelligent lighting take?

In recent years, relying on the concept of things Dongfeng, LED intelligent lighting more speculation hotter. In addition to low power consumption, environmental protection, dimming and color and other aspects of conduct to control the LED, the manufacturers of intelligent lighting another key - Wireless control also sustained attention. Therefore, how to build a smart home in line with the basic needs of low-power, high-efficiency led high bay light price is the wireless vendor priority. In the present there is WIFI, ZigBee, Bluetooth and other mainstream low power wireless communication premise, how do we choose?

WIFI, ZigBee and BLE dispute

We know, WIFI technology research and development due to the low threshold, the low cost of the product, along with a relatively fast speed, coupled with the inherent advantages of direct access to the bridge without the Internet and seamlessly communicate with the phone, making it the choice of many start-ups, this is also reflected WIFI greatest advantage.

But the disadvantage is obvious WIFI manifested, in addition to WIFI chip size is too large, the power consumption is too high, there is the instability caused by poor experience is critical that security issues will bring WIFI I believe this is also an important consideration when buying a key user, so when manufacturing the product, select WIFI products require trade-offs.

In addition, limited WIFI own characteristics, access to the upper limit of their access method primarily limited to the number of WIFI router (typically tens of nodes), which for those of many lighting equipment users, tend to ignore WIFI products.

Another major wireless connection is ZigBee, the low-power wireless control protocol, since the birth of widely welcomed by users and vendors, ZigBee need ad hoc networks, each node in the network can transmit data leveraging, so the need for a centralized network node to manage the entire network, which means that there must be a similar role in the ZigBee network router, complete ZigBee protocol conversion to Internet protocol.

About the "router", in order to visually illustrate, we describe an example of Philips hue, this guy is the hue of additional Starter package inside something called the Bridge, it does not have extra useful, but it can be integrated into other lamps a network, and connected to the Internet.

Learned from the above description, ZigBee brings the most obvious disadvantage is the complexity and increase the cost of installation, also need to connect the phone through the adapter. However, by considering the Bridge to bring more remote access capabilities, coupled with the inherent low power consumption, similar tall on the Philips company, you should choose this option.

So for WIFI and ZigBee, all inch a director, has a short foot. The choice depends on the specific vendor's balance and the user's choice. ‖

Furthermore is the BLE, from its inception in 2009, this technology has become the major manufacturers of "guest of honor", mobile phones, wireless network, and other manufacturers will be such a focus on low power consumption, fast connection, a new generation of wireless communication over long distances communications specifications into their products inside. Intelligent lighting manufacturers do not escape, and prompt attention to this technology into their products inside. Another advantage is that BLE new phones on the market with all the technology, user-friendly connection control of lighting equipment.

Another semiconductor manufacturers also support BLE developers choose another starting point of this technology, such as TI introduced CC2540, Dialog's DA14580 are excellent low-power solutions.

It is worth mentioning that in the Bluetooth 4.1 protocol, BLE products with the MANET features ZigBee only, these are the traditional sphere of influence to attack ZigBee products. Coupled with the standard Apple released iBeacons, this non communication connectivity and greatly increases the likelihood of imagination BLE control products.

If there is a little fly in the ointment in terms of BLE defects if, in addition to the price of the program, led high bay light for sale is money for old mobile phones, since the match is not Bluetooth 4.0 chip, which makes intelligent lighting control devices causing distress. However, considering the modern speed for mobile phone, you will think this is a limitation of it?

Wireless lighting direction

By 2020, the use of the world's Internet-connected wireless lamps and fixtures are expected to grow from 2.4 million this year to more than 100 million, and the development trend of things destined to support these devices can not do without wireless, this wave communications technology will inevitably lead to the dispute. What stands out is the traditional WIFI or ZigBee advantage of a head start, or is a rising star BLE counter-attack? Which would you choose?
