The light bulb seems to be a small object. How to make a smart light bulb and a traditional light bulb separate at a glance? The answer given by Yan Sicheng is that they do not look the same directly. But how to make the bulbs different is still not something that can be done while lying in bed. What materials to choose, what shape to make, and what functions to do are things that should be considered repeatedly.
Open a few crowdfunding websites to see that the hardware of the light bulb has never been so explosive. For why the smart hardware is cut from the perspective of the light bulb, Yan Sicheng still has something to say.

How about Nanoleaf in the US?
Crowdfunding is a good form. For products that are not popular, the crowdfunding website will know. The first generation of Nanoleaf has raised $270,000 on Kickstarter. For most of the products, it is already very good. The second generation is slightly worse, but there are also $180,000.
So what about sales? Yan Sicheng told reporters that they have sold about 80,000 sets, which sounds quite optimistic, because you need to buy a Nanoleaf Bloom bulb on Kickstarter for $40, of course you You can choose to buy it at the official website for $35. You have to praise the big American people on the other side of the ocean or have money.
However, it is necessary to be cautious when logging in to Baidu's future stores. Not only does the initial price drop to 168 yuan, but the limited number of 500 words is also particularly eye-catching. Yan Sicheng said that he wants to sell 50,000 sets before the end of this year, but Lei Feng.com believes that after careful investigation, he should lower his expectations to one thousand.
How does Nanoleaf decide to do it?
The idea came from when Yan Sicheng was still studying at the University of Toronto. At that time, he realized in a solar car team that energy is a very expensive thing. Now that countless energy sources are being used, then energy is being used. What? No, it’s gone. He began to realize the importance of energy efficiency, and the idea of ​​how to improve the efficiency of energy use began to deepen and deepen in his mind. Also in the team, he met like-minded friends, a friend who is very good at power supply design.
So he brought his friend to China, a country with abundant products and rapid development. “I saw that China has a lot of good things, and it is very cheap. I saw a lot of different lights in Guangzhou, but what puzzles me is why the energy efficiency is so low. The energy efficiency of many bulbs is below 80%. The energy of 100W finally only has 80W light effect. So my partner would like to say that we develop a higher efficiency light bulb ourselves." Yan Sicheng is fluent in the "fruit" accent, searching in his mind All Chinese vocabulary says. This is the story of three years ago.
LED is the truth of the light effect of salvation

The bulbs of others seem to be really like a light bulb. Nanoleaf looks like a light bulb-like artwork, not just a stitching trace. The PCB itself is like a semi-finished product, and the shape of the semi-finished material is art. Commonly used techniques. In fact, although it can not be said that Nanoleaf does not pay attention to the value of the face, but energy efficiency is the most words that Yan Sicheng hangs on his lips.
Yan Sicheng did not hide their appearance. "Before making this product, they went to dozens of different light bulb factories and found that basically all the bulbs have aluminum radiators. Why do you want this? No, we start from scratch and don't copy others."
Yan Sicheng has the ambition to say this because they can do it. To achieve a high level of energy efficiency, LED lights are almost the only choice. LED lights have an unparalleled advantage over traditional incandescent and tungsten lamps.
High brightness: ordinary incandescent and tungsten lamps have luminous efficiencies of 12-24 lumens/watt, while LED lamps can reach 80-120 lumens/watt, and may even reach 150 lumens/watt or more in the future.
Low power consumption: 10W LEDs can achieve the effect of 80-100W incandescent lamps, and the power consumption is definitely lower at the same brightness.
Low heat: LED lamps are much cooler than incandescent lamps, and Nanoleaf can be held directly by hand when it is brightest.
Small size: The LED is basically a small chip that is encapsulated in epoxy, so it is very small and very light.
What are the benefits of PCB board as the main material?

Why choose PCB board? It is mainly divided into three aspects. First, heat dissipation, PCB board can be used for convenient heat dissipation, and there is copper sheet behind each LED bulb for heat dissipation. It can still maintain 40 degrees after long-term use. about. Second, it is foldable (compared to glass) and can be folded. Finally, if you use the PCB directly, you can directly insert the bulb. Have you considered other materials? Yan Sicheng said that they have also considered softer boards or plastics, but the PCB board is the most suitable for their needs.
So how does Nanoleaf do it? Divide a PCB into 11 parts, 6 of which are regular pentagons, and 5 of which have two sides. Three small LED bulbs are embedded in each section, adding up to a total of 33. When spliced ​​together, it becomes a bulb that illuminates almost in all directions. This number is a trade-off between cost and light efficiency. Yan Sicheng said that they have more than 90% photoelectric conversion rate and about 10% higher efficiency than the same type of LED bulb. However, Yan Sicheng also admitted to the Lei Feng network reporter that this form has actually been studied two years ago, the LED market is developing very fast, and now there may be a single high-power LED bulb to achieve the same energy efficiency. Of course, Nanoleaf is also researching new products.
Unlike ordinary bulbs, which have a different touch of glass, Nanoleaf gives the impression of a Low Poly product, with a total of 25 edges and a pretty hand-cutting touch. But for Nanoleaf, this is another protection for consumers. When the ordinary bulb glass is broken, the debris will fly out, and it may hurt people. Even if the Nanoleaf breaks, it will not form fragments that fly out. The bulbs are also subjected to special aging and impact tests to ensure that their life and strength are met. (Yan Sicheng said that he doesn't know what a 360-degree rolling test is. It's just an aging test for the product.)
There is a tiny processor in Nanoleaf Bloom that controls the lighting changes of Nanoleaf Bloom. When the switch is turned on, the light will gradually become brighter from the darkest. To the right light level, press the switch twice (on + off) to lock the brightness. But for all kinds of smart light bulbs nowadays, no App may be a feature of both advantages and disadvantages of Nanoleaf. It is good to not occupy the space of the mobile phone, but it can be dimmed by taking out the mobile phone with your fingers. Not the best but there is no need to refuse.
