Here’s another Trinket Contest entry that was interesting enough for its own feature. [Adam] made his own Hackaday version of the Bat signal. It’s not nearly as big, but the concept is the same. Using ...
Many portable appliances and other products that must operate from a single cell are restricted to working at very low voltages. It is thus difficult to drive white LEDs that typically have a forward ...
The circuit in Figure 1 allows you to light any type of LED from a single cell whose voltage ranges from 1 to 1.5V. This range accommodates alkaline, carbon-zinc, NiCd, or NiMH single cells. The ...
Hyundai Mobis has unveiled a new a HLED that's able to be bent as a thin film. The design allows a single LED to serve as both a stop lamp and a tail lamp at the same time requiring only 5.5mm ...
Seoul, Korea (December 5, 2006) – Seoul Semiconductor (SSC, KOSDAQ 046890), a global leading LED manufacturer, announced today the launch of its new LED product, P4. The P4 emits 240 lm at 1 A of ...
This file type includes high resolution graphics and schematics. LEDs are the most efficient way to turn an electric current into illumination. When a current flows through a diode in the forward ...
Sometimes people forget that light-emitting diodes can also detect light quite well. They're usable in a wide range of applications as inexpensive, readily available optical detectors. Typically, an ...
LED, or light emitting diode therapy, is a skincare treatment that uses varying wavelengths of light, including red and blue. NASA originally developed it for plant growth experiments on shuttle ...
