Light, lighting supplies, generally refers to the appliances that can illuminate. from As for candles and oil lamps, Edison's invention of electric lamps opened a new chapter in the history of lighting. Electric lights have different classifications from different perspectives. Smart lights have also made great progress with the vigorous development of intelligent hardware in recent years. Today, it brings you a distinctive intelligence - Hey, light. The difference lies in its control mode. The control of the light has changed from the original direct power cut to the later Bluetooth WiFi， This model uses digital sound to control. Say that voice control will remind you of the ordinary voice control you see in the corridor, With the photoresist, it can be turned on for a while as long as there is sound at night. Of course, the voice controlled bulb Zhang Lei wants to make will not be so simple. In order to give the bulb more intelligent components, he used different audio codes to control the functions of the bulb, such as on, off, brightness, etc. The details are based on my assessment.

First, let's get to know the founder of Hei Deng, Zhang Lei, who is a famous figure. He was once a 360 consultant responsible for 360's security desktop. After leaving 360, he began to make intelligent hardware products and developed Hei Deng.

Unpacking

The three-layer corrugated paper packaging box, using corrugated paper, has low cost and good cushioning. Although the packaging box does not look very noble, the color and pattern are commendable. The main color is solemn and elegant black, and the design is simple and generous. The front is the product LOGO, and the side is the Hey Light pattern and the scanning link controlled by the mobile phone. There are more words on the back, and the parameters of Hei · Lamp are listed.

Just after opening the box, I saw the Chinese logo of the light bulb - Hey, the light, the logo is so big, is it different, is it a little publicity? Hey, the lamp is to be different. If you have a good idea, you should make it known.

Apart from the light bulb, which is two open and close QR codes, how come there is no manual? Is the product easy to use without instructions, or is the product in the trial stage without supporting instructions? Maybe the latter, because there is no warranty card.  

The whole bulb is about the same size and appearance as ordinary bulbs. Compared with other bulbs on the whole, it is slightly slender, such as a girl who stands tall and slim.

The PC material on the top has been optimized for light transmission. The whole top is as round and bright as jade. The LED lamp beads are hidden in it, and the LED power is 8W.

ABS composite material has good heat resistance and insulation. The grooves on the surrounding ring walls are conducive to heat dissipation, but the hardness is poor.

E27 screw, the most commonly used bulb interface model, is very easy to buy in the market.

This is the microphone hole, where the light receives commands. A digital voice control module is built in, By operating the mobile terminal H5 page or APP sends sound combinations of different frequencies to realize multiple changes of bulbs.  

APP Introduction

Explain that both the package and the two QR codes are H5 pages. I think H5 pages are inconvenient to use. Hei · Deng claims that there is no network and Bluetooth control. If you can use page control, you can still rely on the network. Here is a direct introduction to APP. In fact, the two are the same. See the following figure for specific usage.

The control is relatively simple. Adjusting the brightness is like dialing an old telephone. There are ten levels in total, and the color temperature adjustment is divided into five levels. The color temperature range is 2700K color temperature - 5600K color temperature. It should be noted that the specific value of the current level cannot be seen when adjusting the color temperature. I hope it can be supplemented when upgrading the APP.

The APP is divided into single control and multi lamp unified control. I have only one, and the effect of selecting all is the same as that of single control.

experience

As for the experience, I think the brightness of 6-8 is enough for reading. I prefer to read in warm light. Everyone has different hobbies, but I believe that if you adjust it manually, you will find your preferred brightness and color temperature. Here are some photos with different brightness. The Prime Minister declared that they were actually brighter than the photos.

Summary and suggestions

Hey, the design idea of the lamp is ingenious. It can break out of the routine and find a new way. It is really convenient to use. The appearance of the bulb is also very fashionable and beautiful. It is said that Zhang Lei plans to set the price of Hei · Deng at about 39 or 49 yuan, and may set it at 19.9 yuan in the future on the premise of quality assurance. It is good-looking, easy to use, and affordable. It is recommended to use smart hardware. Friends who need smart lights should choose Hey Light.

After a few days of use, I put forward a few ideas with the sole purpose of hoping that the lights will become better and better, and that we can enter every household as soon as possible.

1. It is hoped that the software iteration can be combined with music. The smart light can only adjust the brightness and color temperature, but its function is still thin;

2. I think code scanning is a chicken bone. Although there is no need to install it, you can scan a code every time you turn on and off the lights and adjust the brightness. Code scanning still requires the network, which is a bit troublesome. Personally, it is not as convenient as APP;

3. Whether the controlled voice can be simplified and can be imitated by ordinary people will be more convenient;

4. I hope that common scenarios can be preset in APP, which will be easier to use.
