(Dig hole) RGBWW fill light

Digging holes, RGBWW fill light.

The light board has been completed and boarded.

The side panels are completed and plated.

The driver board is being designed.

The rear panel is being designed.

1. Light panel

1) The light panel is designed with 5 colors, RGB and cold and warm light LEDs, RGB is 8 series and 2 in parallel, cold and warm light is 8 series and 4 in parallel.

2) The light board is a 4-layer black 1.6mm board, which is convenient for wiring and heat dissipation. The positive and negative leads of each light string are drawn out to facilitate the design of the driver board.

3) The light board is led out to a 1mm 16P FPC cable holder. According to the manual, each pin has a maximum of 0.4A. The maximum 120ma for each channel here is sufficient.

4) The lamp board is equipped with an NTC side temperature resistor.

2. Shell

1) The preliminary design of the shell is made of PCB board, 1.6mm white.

2) The top plate is hollow and the middle is light-transmitting, using milky white acrylic plate.

3. Driver board

1) Lithium battery powered, IP5306 2A charging.

2) With a 12832OLED small screen.

3) The LED driver still uses SGM3732, 2.7-5.5V 1.35A MAX.

4) The main control is expected to use ESP8266 and stm32f030.

------------------2022.1.30------------------------------- ---

I took the time to solder the light panel , but I was careless. I was careless and didn't read the manual carefully! ! !

I found that the red LED is reverse polarity, reverse polarity, reverse polarity.

The positive and negative poles of the blue, green, and white 2835 LEDs are opposite. (I checked the red and yellow LEDs of the 2835 and they all have reverse poles.) They can only be soldered in reverse, and they are barely soldered. . . . . .

I have finished drawing the driver board. This version is a test board. After debugging, I found some problems that need to be updated.

-------------------------------------------------- ----------2022.2.8---------------

I soldered half of the board a year ago and wrote the test program. The PWM and LCD programs are basically OK. The attachment is as follows: "2022-RGBWW fill light source program V0.1"

It is quite convenient to use the HAL library.

The light box was initially assembled and tested manually. The effect is as follows:

I wish everyone a happy new year and good luck with the work.

----------------------------------------2022.3.13------ ----------------------------------

Haven't updated for a long time,

The LED board was changed to a double-layer board, with doubled LEDs, shortened volume, and better uniformity.

The side panels are shortened and the two sides are changed for ventilation to facilitate heat dissipation.

Can accommodate 3 18650 batteries.

-------------------------------------------------- 2022.8.1-----------------------------------------

Coordinate 021. I was quite anxious and irritable some time ago. I have calmed down a bit recently. I am sorting out this project. It is not perfect yet. I will put it in the shell and try the effect.

The program is very messy. It was written for testing in March. It can barely light up, and the pictures are also messy. There are no plans to install the WIFI module for the time being.
