Super Bright "Little Sun"

The
boards have been verified, but the casing hasn't been assembled yet. An update will be provided after assembly.
There are two boards: one is a plug-in 15W color temperature LED, and the other is a battery-powered LED with a fan function. The LED board can be magnetically attached to the fan, with a power limit of 5W
. Features of the plug-in 15W magnetic LED: Maximum power 15W, the cooling fan turns on automatically when the light is on, ultra-low standby power consumption .
1. Low-cost solution, simple peripherals, no programming required
. 2. Large component packages, easy to solder
. 3. The LED board uses an aluminum substrate, high heat dissipation efficiency, large copper area, and simple common ground driving method
. 4. The casing has magnetic/power supply functions, side-mounted and top-mounted, convenient for dormitory use.
5. Equipped with a cooling fan, no problem with long-term high-power lighting; test videos will follow
. 6. Low standby current, only 130ua/5v
. Features of the battery-powered fan LED:
1. Low-cost fan/power supply IC, using IP6351, only 0.76r, adjustable battery type voltage and charging current.
2. Uses touch buttons to control the fan switch, with 4 speed settings (5V, 7V, 9V) and 3 wind speeds. Also includes a 4-speed natural wind function.
3. Can be used with an external magnetic light, using the same light board as the plug-in model, with a housing and magnetic power supply magnet that can be attached to the front of the fan. The round power supply magnet supports 360° rotation.
4. Low standby current, only 130ua/5V.
II. Schematic diagram explanation:
Uses PT2023S8 touch dimming IC, low power consumption, standby current only 6ua
, multifunctional, simple peripheral circuit.
LED driver
uses LGS63042EP, input 3-60V, output 3-60V, very cost-effective, only 1.3r, still works normally at 87 degrees Celsius, wide operating temperature range -40℃ to... The 125℃
cooling fan circuit
is controlled by the touch-sensitive LO pin output.
III. Physical/Test Images
: Brightness photos taken using parameters set in professional mode on a mobile phone camera.
Running at full power for 20 minutes without abnormalities, consuming approximately 5.3Wh. It functions well as a plant light. It uses full-spectrum LEDs. With 8 hours of illumination per day, the monthly electricity cost is approximately 4 RMB. The lamp
board temperature is normal (20 minutes of operation, room temperature 29°C). The inductor temperature is the highest, but overall it functions normally.
 
The LEDs used are full-spectrum LEDs; violet light excites the phosphor to emit light. White light is used during operation to be invigorating, while warm light is used at night to induce drowsiness.
