Still networked? It is said that this smart light can be played with sound

36 krypton news, if you have on the market known as smart lights, you must know the process of networking equipment in a lot of pain: Zigbee need to buy Wi-Fi or network gateway, even even faster also need to enter a password, Bluetooth only one connection; the key is to try many times to contact success.

The market is not satisfied with these smart lights, in 2012 after leaving from 360, Zhang Lei began to do a really good idea of the lamp. Now, "Hey, light."!" It has been developed and will be ready for mass production. Its biggest feature is the device does not use "Networking", sweeping code that is used.

"Hey, light!"!" Also use the mobile phone control, Zhang Lei feel that in a long period of time, the phone is still the best smart home controller, but the hardware products and mobile phones before the communication can be more diverse. Compared with Bluetooth, WiFi and Zigbee, the voice is more common, the voice on the mobile phone is more consistent, more general, no compatibility problems, and the use of voice, everyone will be more simple. So, "Hey, light!"!" Sound is chosen as a means of communication.

Do the most direct benefit is used without pairing connection, no need to configure the WiFi password, open a web page, or directly send control voice (your control voice records can be used to "Hey, light)!" Control. The mode of operation is simple, direct and effective. The only requirement is that the user's mobile phone can play the sound.

As for the accuracy of sound transmission signals, there is no need to worry too much. Voice transmission data has a long history of technology, from the earliest DTFM dual tone dial-up, MODEM Internet, FAX fax, these are the use of digital voice for information transmission. Before the Internet there is a very popular application of Chirp, but also through the sound transmission of documents.

The difficulty is that there are no chips or processors dedicated to sound transmission. After all, this is too small. "Hey, light!"!" The existing Bluetooth chip is reconstructed, and the sound transmission is realized on the basis of it. This is not difficult to understand, Bluetooth headset can also transfer audio data.

Compared to the current smart light program on the market, "Hey, light."!" The cost is much lower. The latest edition is a two tone lamp, priced at $39. The team is still trying to make the price of monochrome and so on 19 yuan. As for sales, in addition to the online electricity supplier to attract geeks users, Zhang Lei hopes to be able to put the test board online, allowing users to play, to achieve self-help orders, expanding the average user.

In fact, there are many products that can be controlled by sound, such as voice control socket, voice operated self timer, sound control toy, sound control robot, etc.. Zhang Lei thought, "Hey, light!"!" Just a beginning, light is often used for the longest product family, very suitable for entry; this product if the proof is, perhaps the future will open their own chip, then the lamp price can be lower, and the chip scheme can also be sold to more manufacturers.

Hey, light! Currently, there are four products, which are:

1) is white color, we often say that the sun, can be 10 levels of brightness control, support A B C three independent groups.

2) warm white color, yellow light can be used in family, 10 levels of brightness control, support A B C three independent groups.

3) and double color, support from the white to warm white light mixing five level adjustment, suitable for different family scene lighting, can be 10 grade brightness adjustment, support A B C three independent groups

4) RGB full color, can support continuous mixing light adjustment and brightness control, built-in 10 different scenes of light effect. Support A B C three independent groups.
