Once relegated to the hinterlands of low cost indicatorlights, the LED is again in the spotlight of the lightingworld. LED lighting is now ubiquitous, from car headlightsto USB-powered lava lamps. Car headlights exemplifyapplications that capitalize on the LED’s clear advantages—unwavering high quality light output, tough-assteelrobustness, inherent high effi ciency—while a USBlava lamp exemplifi es applications where only LEDs work.Despite these clear advantages, their requirement forregulated voltage and current make LED driver circuitsmore complex than the venerable light bulb, but some newdevices are closing the gap. For instance, the LTM®8040μModule™ LED driver integrates all the driver circuitryinto a single package, allowing designers to refocus theirtime and effort on the details of lighting design criticalto a product’s success.

LED燈具積小質輕，可選用不同光色的LED組合成照度柔和的各種模塊，任意安裝在居室中，居室照明燈具的光源可能來源于地面、墻面、窗臺、家具、飾物等。因此，未來居室照明將不再局限于單個燈具，而將由單個燈具照明轉化為無照明器具感的整體照明效果的無影燈。
