The polarity markings on LEDs (Light Emitting Diodes) seem to be a common cause of confusion. The polarity may be indicated by a flat section on one side of the body or by one lead being shorter than ...
Witam, kilka lat temu kupiłem w Ikea lampkę z modułem LED Solbacken. Niestety lampka przestała świecić. Pisałem do Ikea z pytaniem jak mogę to naprawić, to mi odpowiedzieli że źródłem światła jest ...
An international research team has developed a perovskite diode that both harvests sunlight at 26.7% efficiency and emits light at 31% efficiency, setting a new performance benchmark. The innovation ...
Witam, Wykonuję modyfikację pewnego urządzenia, dodając zewnętrzne zasilanie. Aktualnie działa wyłącznie na baterii 9 V. Bez wchodzenia w szczegóły. Układ zasilacza standardowy! Tzn. pierwotnie układ ...
In a previous article, we explored the behavior of an LED diode as a small light source. We have seen how important a protection resistor is to light up this component. In this article, we will ...
OLED (Organic Light Emitting Diode) and Mini LED represent two of the highest-end display technologies available today, but they work in fundamentally different ways. OLED panels are self-emissive; ...
I needed a pulsating light for a certain signaling. Voltage was 230V. So I decided to make a simple circuit, consisted of a LED diode, two capacitors, two resistors, a diac and a diode. Activity of ...
