preface:

At present, the connection modes of smart lights can be roughly divided into Bluetooth, WiFi and zigbee. Compared with them, the distinctive feature of Hey Light is that it uses digital sound to control. Speaking of this, you may think of using common voice control lights, but unlike ordinary voice control lights, HEI · lights can adjust brightness, color temperature, turn on and off, and other functions through digital sound.
When I first saw this model Hey, light When introducing, the name attracted me deeply. The word "hey" is usually the mood word of our greeting, and "hey light" is like greeting the light. It said that the light is regulated by digital sound. At this time, my brain thought has flown, "Is it possible to adjust the light by adjusting the volume key of the mobile phone" "Did you call numbers to adjust it, just like a secret signal?" The more I thought about it, the more interested I became. I expected to try it one day earlier. Later, after receiving the product, I suddenly realized that my guess was wrong. How could someone else be so simple? I would never learn the secret signal...

Hei Deng founder Zhang Lei was a 360 consultant who was responsible for 360's security desktop. After leaving 360, he began to make intelligent hardware products and developed Hei Deng. Next, let's learn about Hei Deng with me

The overall packaging design of Hei · Lamp is mainly black. The most remarkable thing is that the white sample of Hei · Lamp is printed on one side of the box, which is quite conspicuous, like a real bulb.

The right side of the pattern next to the bulb is Hey, the name and logo of the lamp are white on a black background.

The next side display of the packaging box is a two-dimensional code that can be scanned and controlled at any time. A scan of WeChat can refresh the page for control.

This side is about the introduction of HEI lamp products. The color of the light source I received is warm white.

Start my journey of Hey Light.

In addition to the lights, there are two two-dimensional codes marked with switches in the light box. It is relatively simple, and there is no manual. It can also be seen that the use of the light is very simple.

Hey, the size of the lamp is about the same as that of the bulb we usually use. The junction of the lamp cap is also the same as that of the bulb. The difference is that the body of the bulb is very different from the components inside.

Hey, there is a clear sign of "Hey, light" under the white lampshade of the lamp

The bottom lampshade can be removed, which is very different from other household lamps. Hey, the lamp has no thin filament, and the exposed small parts are welded on one by one. It is a smart product with great care.

Hey, there is a circle of small grooves on the ring wall around the lamp, which is helpful for heat dissipation and anti-skid. There is a black eyelet near the metal of the lamp head, which is the receiver for receiving sound.

take Hey, after the lamp is installed and powered on, you can scan the QR code to download Hey, the light APP can also be used in the page after scanning with WeChat.

Indicator diagram

The operation is very simple. When I open the app page, there will be a corresponding clear sound. Hey, the light is an LED bulb that can interpret digital sound. There are 1 to 10 levels of brightness adjustment, 1 to 5 levels of color temperature adjustment. Digital sound is used as the control mode. It uses a sound that lasts less than 1 second, like chirping birds, It is encoded into dozens of different instructions, which sound similar to each other, but are different instructions, such as switching, lightening, darkening, color conversion and other operations.

The following is the expression of founder Zhang Lei

Click "All", and there will be corresponding ABC groups. If there are multiple lights, you can group them.

Hey, there are four products of the lamp at present, which are normal white monochrome, warm white monochrome, cold and warm dual color, RGB full color, respectively corresponding to daylight, yellow light, and normal white to warm white five level mixing adjustment and support continuous mixing adjustment, of which the first three can be adjusted for 10 levels of brightness, and RGB full color has built-in light effects of 10 different scenes.

If you want to read a book, watch TV with a projector, or turn on light with low brightness, you are recommended to choose Hey, light, I have experienced it, and the effect is still very good, because I want to be busy with other things when the brightness is not very strong Hey, adjust the light to a proper brightness, and have the best of both worlds.

Advantages brought by digital sound control

First, the operation is simple: as long as the control sound can be sent, you can control the light without connecting to WiFi or Bluetooth;

Second, there are various control methods: if you scan the code, you can control it immediately. If you scan the QR code next to the light, you will open a web page. You can operate the relevant buttons on it, and the phone speaker will make a sound. After the light bulb receives the sound, you can carry out the relevant operations. You can also use the Hei Deng App to control, without networking and pairing, and even record the control sound;

Third, there is no compatibility problem: compared with Bluetooth, WiFi and zigbee, voice is more common, and voice performance on mobile phones is more consistent and universal, so there is no compatibility problem.

in use Hey, the problem with the lamp:

1. The response is not so sensitive. I said that within 10 meters, when I was close to the light, when the environment was very quiet, I sometimes did not respond. Every time I operated the phone, the voice was turned to the maximum.

2. It is controlled by sound and has certain requirements for ambient sound. It is not suitable for use in particularly noisy environments.

3. It can be used by one person after sleeping and waking up at night. After all, the sound does not affect other people. If other people sleep in front of them, it will be inconvenient to use and will wake them up.

4. It is said that the Internet is not necessary, unless the app is downloaded well, if you use WeChat to scan the QR code, you still need to use the Internet.

5. The brightness and color temperature in the middle are not very different.

6. The control sound can be more pleasant.

I still like to use Hei · Deng. I hope that Hei · Deng can become better and more affordable, so that more users will like to use it.
