DESCRIPTION

LEDs, or lightemitting diodes, are semiconductor devices that produce visible light when an electrical current is passed through them. LEDs are a type of Solid State Lighting (SSL). LED lighting differs from incandescent and compact fluorescent lighting in several ways. When designed well, LED lighting can be more efficient, durable, versatile and longer lasting.This presentation compares the three common types of bulbs on the market today: LED, Incandescent and Compact Fluorescents (CFLs).

<p>PowerPoint Presentation</p> <p>LED Lights vs. Incandescent Lights vs. CFLs</p> <p>What are LEDS?LEDs, or lightemitting diodes, are semiconductor devices that produce visible light when an electrical current is passed through them. </p> <p>LEDs are a type of Solid State Lighting (SSL), as are organic lightemitting diodes (OLEDs) and lightemitting polymers (LEPs).</p> <p>How is LED lighting different than other light sources, such as incandescent and CFL?LED lighting differs from incandescent and compact fluorescent lighting in several ways. When designed well, LED lighting can be more efficient, durable, versatile and longer lasting.</p> <p>LED lighting products use light emitting diodes to produce light very efficiently. An electrical current passed through semiconductor material illuminates the tiny light sources we call LEDs. The heat produced is absorbed into a heat sink.</p> <p>Common LED colors include amber, red, green, and blue. There is actually no such thing as a white LED. </p> <p>To get white light the kind we use for lighting our homes and offices, different color LEDs are mixed or covered with a phosphor material that converts the color of the light. </p> <p>The phosphor is the yellow material you can see on some LED products. Colored LEDs are widely used as signal lights and indicator lights, like the power button on a computer.</p> <p>LEDs are now being incorporated into bulbs and fixtures for general lighting applications. LEDs are small and provide unique design opportunities.</p> <p>Some LED bulb solutions may look like familiar light bulbs and some may not but can better match the performance of traditional light bulbs. </p> <p>Some LED light fixtures may have LEDs builtin as a permanent light source.</p> <p>Energy Efficiency and Costs</p> <p>Life Span (Average)LEDsIncandescent Light BulbsCompact Fluorescents (CFLs) 50,000 hours 1,200 hours8,000 hours</p> <p>Watts of electricity used (equivalent to 60 watt bulb). </p> <p>LEDs use less power (watts) per unit of light generated (lumens).
