Xiaomi Department Store has more and more styles, not limited to mobile power, smart devices, clothes, footwear and socks, and recently introduced a very interesting cross-border products, portable flashlight. 
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
It not only has the function of a flashlight, but also has a mobile power function of 3350mAh capacity, and a single 18650 mobile power source with a combo function has many brands before the flashlight.
But only straw hat LED, practicality is not enough, millet this flashlight with rotating dimming function, 11 file brightness, 360 degree rotation, turn left light, turn right is from low to high, to the brightest, controllability Well, the magnetic ring dimming is also my favorite anti-dimming method. It is convenient and direct, and the brightness is free.
First, appearance
Outer packaging, transparent shell.
Cylindrical plastic shell, the tail is a sticker, the upper rack hole.
The bottom sticker is the parameter, the manufacturer, see from the logo, this is Jiangsu purple rice production, the model is LPB01ZM. The name is: Millet with a flashlight. Using a 3,350mAh capacity ** battery, the shape can be judged to be a single 18650 battery, mobile power supply 5V1A input and output, the light source is 3W.
The other side of the sticker is a bar code label.
Transparent shell can directly see the flashlight inside.
The bottom can see the accessories inside.
Two synthetic transparent plastic shells, a charging cable, a rubber lanyard, and an instruction manual.
The entire flashlight is made of aluminum alloy with silver on the top and beige on most of the bottom.
MI brand logo, parameters, manufacturer information, etc. are printed on the front.
The switch position is affixed with the label, there are recommendations, three consecutive hits to open the SOS neighborhood function, click to exit the SOS mode, the operation is simple and easy to remember.
Open the description sticker, which is a USB-A output, a micro charging input, and a button.
Press the middle button of the button to light up. At the same time, this button is the function button of the SOS. 3 button can activate the SOS mode to facilitate emergency assistance.
The lamp part is also a sticker.
Inside is the lamp beads.
It looks like a lens. It also has yellow water.
The benefit of the lens is that the spotlight is easier to control and can be made smaller.
The head of silver accounts for a quarter.
A cylindrical lens is seen from the side.
The keys are recessed a little to avoid the possibility of a false touch.
The silver part can be twisted, that is, dimmed, and the white part is clearly indicated.
Spot effect.
1 meter spot.
Irradiation of the object spot transition is still very comfortable and will not be particularly dazzling.
With ChargerLab power-z FL001 tester, one-click protocol detection, fast charging protocol does not support.
Charge 1A.
The load is just 5V1A, 1.05A protection.
No load 5.168V, output without line compensation.
The minimum brightness.
The same exposure value, the highest brightness.
Apple phone 1A.
The Android phone is also 1A.
Second, dismantling
First open the lens and you can directly pull it out.
The lens is a single piece of organic glass.
Lens side.
The bottom of the lens.
The front of the lens.
Just accommodate the lens position.
The lamp beads are centered with two fixing screws and the other two holes are where the circuit compartment is opened.
Lamp beads, according to the official anti-parameter is LUMILEDS 3W led lamp beads.
Lamp bead side.
Everyone is very interested in this lamp, one more picture, PCB substrate.
Lens bay, recessed place just put the lamp beads.
It cannot be beaten here.
Cut directly.
Part of the damage was found to be very deep.
Violence was cut, part of the shell, and the aluminum shell was still a bit thick.
Inside is a deep lid with snaps.
The inside of the cover is a PCB, a battery connection, USB output.
The seat is the largest, accounting for half of the PCB area.
PCB side.
The front of the PCB is fixed with a foam underneath.
The big picture should be Yu Lijie's plan SY6918.
This IC is estimated to be purple rice custom silk screen ZMF1206USBN.
A six-wire cable is used to connect the PCB to the head of the LED. The control power supply is on six wires.
Look at the barrel again, there is a PCB, the 6 wires just welded above.
The bottom of the battery has a plastic protective cover and the nickel solder joints are neat.
There is a temperature control probe on the side of the battery and the purple rice series has this kind of temperature control.
Pins in 6 positions on the board.
Look at the ratio of the 18650 battery to the housing. Purple battery, LG3350mAh capacity.
360-degree rotating light circle, cut straight
There are gears inside, and the circuit compartment has two black aprons.
The circuit compartment can be directly twisted and threaded. Circuit box white gear, dimming by turning the dimming.
The circuit housing is directly threaded with the barrel and hits a little glue.
Want to open without loss, provide a reference, pull out the lens, twist the seat can be.
The white accessory on the right side covers the gear.
This white accessory is positioned on top of the gear.
Contrast with 1 yuan coin size.
Directly close to 1 dollar coin.
One dollar coin with PCB lamp head PCB.
The PCB size is smaller than a one-dollar coin.
The structure diagram is convenient for users to open and reform themselves.
This is a soft plastic cover.
It is a key, it is hidden deeply.
There is a long needle in the lid and touches the button inside.
There is a snap in this position. It should be used directly to position the body.
The missing place is where the dimmer ring comes in contact with the white gear, twisting the gear to dim.
LED out of the PCB.
gear.
The side view is the encoder, not the guessing of the magnetic ring dimming, the dimming sound is also from here.
In the LED position, many via holes are used to enhance heat dissipation.
Below the encoder is a gear.
All dismantled items.
Third, summary
In the traditional single-cell mobile power above the added flashlight function, 11-level dimming is the most convenient place to break before the similar product design.
At the same time provide the brightness to the 3W output, there is an SOS function for emergency assistance, compact size, is a convenient portable flashlight, also has a mobile power function.
Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.
