Still in networked control? This smart lamp is said to be able to use sound.

36 krypton news, if you have used the market known as the smart lights, you must know how painful the process of networking is: Zigbee needs to build a network or buy a gateway, Wi-Fi even if it needs to lose the password quickly, Bluetooth can only be connected one by one; the key is to try many times to succeed.

Zhang Lei was not satisfied with the smart lights on the market. After leaving from 360 in 2012, he developed the idea of making a really good lamp. Now this "Hey lamp!" It has completed the development and is about to mass production. Its biggest feature is that the device does not need to connect to the network, and the code is used.

"Hey, lights!" It is also the use of mobile phone control. Zhang Lei feels that for a long time, mobile phone is still the best smart home controller, but the communication mode between hardware products and mobile phones can be more varied. Compared with Bluetooth, WiFi and Zigbee, voice is more common. Voice performance on mobile phones is more consistent and universal. There is no compatibility problem, and the use of voice is easier for everyone. So, "Hey, lights!" Voice is chosen as communication mode.

The most direct benefit of this is that there is no need for pairing connections, no need to configure the WiFi password, to open a web page, or to directly control the voice (you can use the control voice to record), you can say "Hey! Light!" Control. The operation is simple, direct and effective. The only requirement is that the user's cell phone can play the voice.

As for the accuracy of sound transmission signals, there is no need to worry too much. The technology of voice data transmission has a long history. From the earliest DTFM dual tone dialing, MODEM Internet access and FAX fax, all these are the use of digital voice for information transmission. Before the Internet, there is a popular application of Chirp, which also uses voice to transmit files.

The difficulty is that there is no chip or processor developed specifically for voice transmission. After all, this is too small. "Hey, lights!" The existing Bluetooth chip is transformed, and the voice transmission is realized on the basis of the existing Bluetooth chip. This is not difficult to understand. Bluetooth headsets can also transmit voice data.

Compared to the current smart lights on the market, "Hey! Lights!" The cost is much lower. The latest version is a dual color lamp, which sells for 39 yuan. The team is still striving for the price of monochrome to achieve 19 yuan. As for sales, in addition to online business to attract geek users, Zhang Lei hopes to put test panels online, allowing users to play, to achieve self-service orders, expand ordinary users.

In fact, there are many products that can be controlled by voice, such as voice activated sockets, voice activated self timer, voice controlled toys, voice controlled robots, etc. Zhang Lei thought, "Hey, lights!" It's just the beginning. The lamp is the longest product used in the family. It's very suitable for cutting in. If the product proves to be right, it may open its own chips in the future. By that time, the price of the lamp can be lower, and the chips and programs can also be sold to more manufacturers.

Hey, lights! There are four products at present:

1) positive white monochromatic, which is what we often call sunlight, can carry out 10 level brightness control and support A B C three independent groups.

2) warm white monochrome, commonly used yellow light, can carry out 10 level brightness control, support A B C three independent groups.

3) cold and warm dual color, which supports five level mixing adjustment from white to warm white. It is suitable for different family scene lighting. It can carry out 10 level brightness adjustment and support A B C three independent groups.

4) RGB full color, which can support continuous blending and brightness control, and has 10 different scenarios. Support A B C three independent groups.
