Discrete LEDs vs. Packaged Solutions
Designers use LEDs in three basic applications....either as a diagnostic indicator on a circuit board inside a piece of equipment, for front panel status indication, or illumination. These applications can be served by either discrete LEDs (see Fig. 16) or by packaged solutions such as DialightÕs Circuit Board Indicator (CBI) Series that combines an LED with a plastic housing (see Fig. 17). While discrete LEDs may appear to have an advantage in ...
LUXEON LEDs Take Retrofit Bulbs to the Next Level - Trusted
Light source of Philips’ winning L Prize bulb is enabling high quality retrofit bulbs around the world
ZLP Series Low Profile LED
JKL Components Corporation announces the addition of the ZLP Low Profile Series LED to its family of linear LEDs and high bright lighting components.
New automative LED driver from Supertex reduces board space while improving system reliability
Supertex, Inc. has introduced AT9919, an LED lamp driver integrated circuit (IC), designed specifically for solid-state lighting applications in automobiles, such as head lights, tail lights, brake indicator lights, dome lights, and panel backlights.
Light Guides
Light Guides are used wherever the light of a lightsource should be distributed homogeneously over a particular area, when there is a spatial distance between light source and the area which is to be illuminated.
Philips introduces Fortimo LED high brightness module
Philips has announced a new addition to its Fortimo LED family - the Fortimo LED High Brightness Module (HBM). Fortimo LED HBM is an easy to design-in, compact, high lumen LED module for white light applications.

New UV LEDs Combine 10X Longer Lifespan and Up To 50% Cost Savings
Lumex announces the global expansion of the QuasarBrite™ UV family of LED technologies to include three new standard wavelengths and also announces the availability of custom UV LED arrays. QuasarBrite UV LEDs provide up to 10 times longer lifespan, up to 50% cost savings , up to 70% energy consumption savings, and superior light performance compared to alternative technologies.
Warranty Cost Savings of LED Signal Lights
LED lamps have a significantly higher reliability than incandescent bulbs. The potential savings in warranty repair when using LEDs instead of incandescent bulbs is highly attractive for automotive signal lamps—especially center high mount stop lamps (CHMSLs) and rear combination lamps.
Drives 1-2 Luxeon LEDs at different currents from separate power inputs
This circuit is designed to replace a dual-filament incandescent bulb in a combined brake/tail light for automotive use. When power is applied to the 'Tail' input the current in the LED is regulated to 300mA. When power is applied to the 'Brake' input or both inputs simultaneously, the current in the LED increases to 900mA. The 'Brake' and 'Tail' input voltage can vary between 8V and 40V This makes the circuit suitable for standard passenger cars...
