Today, there are a few key industry standards and specifications that should be studied before undertaking your LED retrofit bulb or outdoor luminaire design. UL 8750 was created recently and is the ...

Inspired by printed circuit boards, the building block of all electronics, a Dutch designer has created an LED-based light installation that draws upon the familiar etching pattern inside most ...

ESD (electrostatic-discharge) events or surges induced by nearby lightning events are another common cause of LED failure. Typical design example. Figure 1 shows a typical LED lighting system. In any ...

A LED light pipe is an optical fiber or a solid transparent plastic rod for transmitting light from an LED mounted on a printed circuit board (PCB) to the user interface. Light pipes transmit up ...

The Fig. 1 example includes LED loads D1 + D2, D3 + D4, D5 + D6 and a power-supply output voltage, with a constant output current, providing the circuit input voltage (V IN).

Many equipment manufacturers prefer protection circuits combining resettable overcurrent protection devices with upstream fail-safe protection. In this example, R1 represents a ballast resistor used ...

This article explains the root of the problem and makes recommendations for ensuring ceramic capacitors do not cause lifetime problems for LED lighting products. Typical conditions in LED circuitry. A ...

With the lighting industry trending toward LED use, it is becoming increasingly common to string large quantities of luminaires on a single circuit due to the decreased load per luminaire. Now more ...

Analog design Tip: A Simple Circuit to Protect Against Open LED Faults. Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly ...

Energy efficiency: A 6W LED bulb can put out as much light as a 50W halogen bulb. I’m not sure that swapping all the lights in my small apartment will make a huge dent in my annual bill or our ...
