For several years manufacturers have been introducing LED bulbs onto the market with the eventual goal of replacing incandescent and CFL lamps. The design of these lamps has evolved from very simple ...

LEDs are more efficient than incandescent lights and can last 100 times longer, but they require specialized electronic-drive circuits to avoid overstress conditions. The main operating parameter is ...

As high-efficiency ultra-bright white LEDs come down in cost, they are approaching cost parity with conventional mercury vapour, HID quartz metal halide and high/low pressure sodium lighting on a cost ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...

This code supports Application Note AN1138: A Digital Constant Current Power LED Driver, using the PIC12HV615? an 8-pin, PIC microcontroller (MCU) with many integrated analog features. The LED driver ...

The quest for energy efficiency has led manufacturers to investigate ways of dimming all kinds of lighting technologies, including those that usually can’t be dimmed. Consider, for example, ...

LEDs may be garnering the most headlines these days. But high-intensity discharge (HID) lighting is as popular as ever, too, thanks to its high brightness, excellent color temperature, high ...
