无线个域网/ Wi - Fi/BLE intelligent lighting control what model?

Under the wave of the Internet of things, what choose what kind of communication mode connect hardware and cloud? This is all intelligent hardware entrepreneurs and consumers feel headache. As the most fashionable and the lamp factory of science and technology, ZigBee dared to introduce the three patterns, Wi - The difference between Fi, BLE. I think no one more than we yeelight suits to introduce, because now have three smart lighting products on the market, just corresponding to three models, by the way, we also explain yeelight blue hue difference.

1色调。 ZigBee

ZigBee under the first explain the origin of the name. After found flowers bees will pass a special body language to tell the companion of the newly discovered food source location information, such as the body language is a ZigZag line dance, is a kind of simple way of conveying information between the bees. Take this meaning ZigBee as the naming of a new generation of wireless communication technology. Philips hue used ZLL ( 光无线个域网链接) Is on the ZigBee protocol developed a set of extension, the agreement dominated by philips, hope to be able to more simple implementation lamp intelligent connection, first product hue can say from lighting opens up a new era in the history. ZigBee is low speed, low power wireless control protocol, network characteristics can be automatically, means each node transmission data of network in the network to a central node to manage the entire network, which means that the ZigBee network must have a role similar to a router, complete ZigBee protocol to Internet protocol conversion, the extra guy is the Bridge of the inside of the hue of the Starter package, which itself has no additional useful, but other lamp can be integrated into a network, and connect to the Internet. Harm is to increase the cost, increased the complexity of the installation, and can't be our mobile phones directly connected, must want to transfer, benefits by Bridge, can let the ZigBee lamp is connected to the Internet, and have the ability more remote access ( Also means that risk) , hue is based on the technology of products, support about 50 per subnet node. ZigBee products are usually low power consumption, the cost is relative to the Wi - Fi product lower, bluetooth products with low power consumption. Hue first generation using the TI 253 x as light, belong to moderate performance-to-price ratio is relatively mature ZigBee scheme, from the aspects of optics, philips is worthy of lighting industry for many years accumulation, not only from the aspects of color temperature more impeccable, in the aspect of color also can realize most of the color gamut range, but after the second generation cuts, lower costs, reduced nearly 40% of a much lower light bead is the sincerity. Another hue is expensive to even complain about the price of the old beauty, introduction to suit 1699 yuan, including three light bulbs + a gateway, well, it's local tyrants.

2 Lifx . Wi - Fi

Wi- Fi, believe that all of us are familiar with, is all of us on the phone's built-in network protocol, using the Wi - Fi deal Lifx intelligent lighting products also can directly connected to the Internet intelligent lighting products, of course, can also directly from the access to the phone. Wi - Fi advantage is relatively fast speed, can need not bridge direct access to the Internet, and can be seamlessly communicate with mobile phones, the major disadvantage is that the relative up Wi - Fi chip encapsulation slightly larger size, and power consumption is higher, Lifx standby power can reach up to 1 w, and BLE and ZigBee typical standby power consumption at 0. 1 w, and from the actual test performance, Lifx on color gradient capability and thermal control is still underdeveloped, within the volume of the ball bubble lamp for the maximum power of 17 w design, there are greater risks ( Voice-over: this lamp can live for a long time! ) 。 In theory, WiFi access online access is mainly limited to the number of nodes (WiFi router Typical values for dozens of node) 。 Another, is now widely concerned about safety, think about if the inside of the smart home products by Wi - Fi connection, one thousand which day was black, was a little scary. 3 yeelight蓝色。 BLE

BLE( Low power consumption bluetooth) Is the latest focus on low power consumption, Sustainable standby button battery for more than six months) , fast connection ( Only 1 - 3)女士 And long distance communication ( More than 50 m) A new generation of short distance wireless communication standard, with a special focus on and optimize the small packets of data exchange, can be said to be for the Internet of things different vendors IOT ( Interoperability testing) Tailor means of communication era, the disadvantage is that can't be old smartphones support ( Support only after 4 s iphone and Android4. After three Android phones, good friends in the phone, mobile phone is very cheap now, you don't say) But as time goes by, most modern smartphones have to support, is rapidly becoming a new generation of intelligent hardware standard communication protocol. After apple released iBeacons standard, this kind of connectivity of communication has greatly increased the likelihood of BLE control product and imaginary space, published in the behind of the bluetooth 4. 1 agreement, BLE products have ZigBee to some ad-hoc network characteristics, these are moving in the sphere of traditional ZigBee products, yeelight Blue products as a representative of BLE intelligent lighting products, also in the rapid absorption standard communication protocol, the benefits of upgrading to more powerful capacity and low cost to intelligent lighting.
