Since Edison invented the electric light, the use of electric light has penetrated into all aspects of our lives and has become an essential daily consumer goods. The traditional light bulbs are manually turned on and off by switches, which is very inconvenient to use. Especially when the room is completely dark, it is a challenging task to find the switch. Then came the voice control lamp, which can be controlled without switch, but still can not control the brightness. With the development of science and technology, more and more smart lights appear in people's lives. The author has seen many smart lights, which are basically connected to mobile phones directly via Bluetooth or indirectly via ZigBee. Whether you use Bluetooth or ZigBee to WiFi, you need to connect wirelessly. In addition, the smart light bulbs on the market can basically respond to APP commands, and several bulbs change colors. Until the appearance of HEILIANG, the author's concept of smart light was completely overturned

Zhang Lei, the founder of Hei Deng, 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. Hey, the light looks ordinary, like a general LED bulb, but it can control the switch and brightness with a mobile phone. The key surprise is that the mobile phone and the light bulb do not need to be connected to the Internet, and can be achieved only by scanning the code. Isn't it amazing?

Once upon a time, we lingered in the dark corridor, stamped our feet or shouted for light. This is the most primitive voice control, which has only two states - on and off. The HEILIANG is different. In addition to the switch, it also has the adjustment of brightness and cold and warm colors, which requires very complex logic. It sounds like a bird's call, but it is encoded into different commands. The human ear sounds like each voice command is not different, but HEILIANG can distinguish different commands. In fact, it's not just mobile phones. Many voice devices can give commands to HEILIANG.

The following is a brief introduction to the features and detailed usage of HEILIANG. After receiving the express One A plastic bag containing a Made of ordinary cardboard Black box. Creative white patterns and words are printed on the black background. See if the style is simple and creative.

The shape of the product is also marked on the outside of the box.

Is the QR code controlled by scanning code somewhat different from the smart light controlled by APP? In fact, this is innovation.

In addition to the QR code printed on the other side, it is also marked in detail How about brand, size, weight, interface type, process material, light source, power consumption, brightness, service life, company name and official website? Is it comprehensive?

Open the box and let's have a look at the real face of Lushan Mountain. The white plastic lampshade is printed with the word "Hey Lamp". Xiao Bian can't wait to take it out.

The overall feeling of the bulb is quite long, Standard E27 light port, The plastic part of the lamp head adopts the frosting process, and the lower part is the ceramic lamp body, and there are many grooves to help heat dissipation. Exquisite workmanship and beautiful lines make people stand out.

Compared with the ordinary bulb, there is a hidden microphone to receive the sound, just at the lamp mouth.

There are also two square QR codes in the box, which are printed with on and off respectively. They should be used to control the light bulb.

Unscrew the plastic lampshade on the bulb, and you can clearly see the LED patch inside. The workmanship is exquisite and the quality is reliable.

Compared with the ordinary E27 bulb, it is really longer.

After scanning the code, Jump to an H5 page, and you can control the Hey light, including switch 、 Brightness adjustment and Color temperature adjustment and other operations to adapt to the requirements of lighting in different scenes. The principle of HEIDIAN is that it has a built-in digital voice control module, and H5 page can realize multiple changes to the light bulb by operating the mobile phone to send sound combinations of different frequencies (of course, in actual use, the official APP can also be installed to achieve more control functions.). Of course, in consideration of the ambient sound, HEILIANG adopts a unique audio coding to prevent external interference. However, the transmission distance of voice control is limited. Brightness adjustment is divided into Level 10 ， Color temperature adjustment is divided into Level 5, the APP download interface is at the top left corner of the page, and the purchase interface is at the top right corner (after clicking purchase, the user can Jump directly to Place an order on the purchase interface of WeChat store ）The upper part is the brightness indicator, and the central ring is used to adjust the digital gear（ The brightness can be adjusted by just flipping the ring ）, the switch function interface and Color temperature adjustment interface. The phone speaker will make a sound to adjust the brightness and temperature of the bulb.

After it is installed on the desk lamp, it seems that the length is a little beyond the protection range of the lamp shade, which cannot effectively block the light. The brightness adjustment is not particularly obvious from the picture.

Summary:

Advantages: The biggest advantage of HEIDENG is that it uses voice control, which is simple to operate. You can scan the code without installing APP. Of course, you can also install APP if you don't want to scan the code every time. Easy to use and operate. I have to admire the founder Zhang Lei's creativity and dedication to the light bulb.

Disadvantages: The package is a little rough. Can you consider adding a manual; In addition, the voice control is not particularly sensitive when it is far away from the HEI light; The color temperature adjustment function is not very obvious.
