Abstract: In this paper, a type of integrated LED module comprising LED source, freeform lens and hexagonal absorbing wall was proposed to be utilized in local dimming for LED backlight to move away ...
This design generates PWM signals on GPIO pins 25, 26, and 27, that can be used to drive MOSFETs to control 'dumb' RGB LED strips (opposed to inteligent LEDs). I used the SI4944DY SOIC8 DUAL MOSFET ...
Abstract: To cool the high-power light emitting diode modules (LEDM) in lighting device it is promising to use two-phase heat transfer devices (TPHTD) - thermosyphons (TS) and heat pipes (HP), the ...
Parola is a modular scrolling text display using MAX7219 or MAX7221 LED matrix display controllers using Arduino. The display is made up of any number of identical modules that are plugged together to ...
