When I was obsessed with Yeel ink, I also got a Bluetooth version to play, and I got rid of it. Let us see why LIFX is so expensive, and is yeelight really cheap?
Originally, I should take the yeelight millet version to remove it. After all, it is a zigbee version, but in theory the basis of these two products is the same, that is, the difference between Bluetooth and zigbee, and yeelight is too popular, and it is impossible to buy it at Xiaomi Mall. I had to remove the Bluetooth version. If someone feels that there is no comparability, then I am sorry, don't continue to read it, or look at the yeelight BLE version of the misfit bolt for a reference?
Ok, let's start counting.
Start with the light-emitting part, aluminum substrate + LED
The aluminum substrate is 1mm thick and is the best price. 1.5RMB is the best quality.
LED, white light 3, RGB one each, a total of six, all CREE , all in this circle understand, 5 one, almost the retail price, a total of 30RMB. In addition, Xiaomi website publicity has a very important sentence, CREE white light bead, this is the first meaning of two layers may not be high-power, it may be medium power, and second, that is RGB color lamp beads must It's not CREE, and since I didn't say the brand, it must not be a big factory. If you have a conscience, estimate Taiwan. You can also see the picture of misfit and the new yeelight blue II. It should be medium power. Here, huh, there are at least 5 savings.
This time the motherboard to the motherboard 2540
2540, this Taobao has a price, the use of intelligence is in use, 10 pieces are also considered retail price, other accessories and PCB board, 5 pieces up. This motherboard 15, knowing the line must know how much I have to say.
Ok, there is another big ACDC and DCDC.
Before the calculation, I spit a slot, 7W ACDC, the circuit design can not do, so I have to have a DCDC, this point yeelight can get solved after getting the investment, the cost of DCDC can be saved. ACDC, 7W, the retail price is 10, the DCDC is so small, the basic 5 can be fixed, the total price is 15.
Well, the shell male model is 5 blocks, 4.99 LED bulbs, how much the shell can be worth, count the mold, count the packaging, count 7.5
How much is total: 5+30+15+15+7.5=72.5
What is the price? I have always said that the retail price, that is, if you will do, this price, you can make one, tens of thousands, what is the price of 100,000? I won't say it, and then I will hit me. Manufacturing is not easy. Leave some space for them. Remember, no, I said that the lamp is replaced. I said that the DCDC has been solved. It can be seen from the pink picture of yeelight. There are 15 cost savings here. Of course, the zigbee version will be more expensive. U disk, leveling, in theory, can be said that Xiaomi gets the goods from yeelight at this price, millet profit is 129-72.5=56.5, is it much more than everyone's 4.99 every day, and this is only 6W bulb added Bluetooth.
Yes, forget the misfit, this yeelight foundry, the medium-powered Bluetooth light, 49.99 dollars, look, Xiaomi earned it is pretty cool.
Maybe there will be people who will say that there are still software in the family, or design, these are intangible, okay, look at the comparison:
This is TI's free development kit, the program is designed to use:
This is the yeelight board and app
Yes, this is LIFX
Ok, let's say you have to be beaten. If you talk about the experience, don't say it. Try it yourself. I said that lifx is the coolest. People sell 99, don't talk about chips. People use 1W white light and use 8 people. The films are all ARM M3, domestic, and the amount. . . . Yeelight is not really good.
Is the LED intelligent?
What kind of intelligence does the home need? Why do you want to toss a light bulb into an audio? camera? router?
In fact, it just wants to quietly illuminate the night, so simple.
