Philips hue smart bulb dismantling

I took a friend, measured the ingredients, put on the gas mask with a gas mask, and blew it for two days. Finally, I took it out and it was tears. . . . . .

Compared with the HUE disassembled by the previous Jianggong team, the number of new HUE LEDs has been greatly reduced from 11 to 7. Why can it be reduced? Look at the picture first, then slowly

This is the part of the LED board disassembled by the ginger worker.

This is the latest way to get it out:

Is it a little different? 11 pieces were reduced to 7 pieces, the aluminum substrate was saved, and the PCB was used, but all the parameters were unchanged. How to do it? And why is Philips using RGB mixed light, is that really G?

Ok, let me analyze it for everyone, and then everyone can easily find out what I said in LIFX. HUE is the real boss, the ultimate in optics. Of course, due to limited space, this time it’s probably a big talk. Dismantling, HUE optics, I will write a separate article to talk about, amount, but to help HUE achieve the perfect optical system circuit is not to say ah, hey, can say too much, in addition to control, HUE really very perfect.

Let's say that 11 is reduced to 7. HUE uses the technology of mixing light. Those who feel this technology must be masters. How many domestic brands in the past year, HUE said, but they all adopted OSRAM. What is the RGBW solution for TI? Simple, W is responsible for white light, other is responsible for flirting, oh no, responsible for coloring, irrelevant, LIFX has developed some, between the two, of course, LIFX also understands that there are so many needs for flirting, so You will find that LIFX is a white light with a specific color temperature. HUE is a white light of 2700-6500. If you see the gap, HUE's optical algorithm should be the strongest. See the small white film in the third chapter. Is this thing decorative? Of course not. The reflectivity of this thing is higher than that of aluminum. It’s better, until next time. That's right, what is the yellow LED, is it G? Of course not, what is it, continue to say next, don't cut me, this time it is good to talk about dismantling.

Why did you start to choose 11? This is rebel, 1-3W, 11 is how much, at least 11W, where is the power going?

Let's take a look at the power board and motherboard.

Dachang production must be a boutique, look at this work, compared to yeelight or something, can you? Far away, 2530 with PWM, control three LEDs, in order to balance the three-way voltage drop and output, the first 452 is a helpless choice, it must also require the board to be low output, and the new circuit, Philips do The improvement, it should be the power supply part, turned into a 2+1 output, and the particles naturally fell.

To sum up: Philips' design idea is very simple, mixed light to achieve large color gamut, zigbee 2530 to achieve wireless control, 110-240V 8W ACDC is responsible for providing power, on these three points, interested can challenge, there are pits, and pits are very Big, very deep.
