APPLICATION NOTE VISHAY SEMICONDUCTORS www.vishay.com Optoelectronics Application Note VLPC Light Modules Thank you for choosing the VLPC Light Modules from Vishay. The VLPC Light Modules are designed for integration into luminaries. This application note provides key attributes for design. If you require any further information or support, please contact your sales representative or visit www.vishay.com/leds. INTRODUCTION High-power LED technology in common lighting applications provides improvements over incandescent and fluorescent lighting systems. Longer life, lower power consumption, and less light pollution in outdoor applications all favor rapid adoption of LED-based lights. In addition, LEDs have a variety of color temperatures giving light designers the flexibility of using cool or warm lighting similar to colors provided by fluorescent lights. LIGHT SOURCE LIFE EXPECTANCY (h) Incandescent (100 W) 750 Compact fluorescent 6000 High bright LED up to 50 000 The emission pattern of the LED determines the coverage of area being illuminated. The VLPC Light Modules do not have COLOR TEMPERATURE an associated reflector to change or redirect the light from Warm white 2600 K to 3699 K the LED. In most applications, a simple diffuser is assembled to cover the LEDs for cosmetic purposes. These Neutral white 3700 K to 4999 K due not change the characteristics of the emission. The Cool white 5000 K to 7000 K LEDs used in the VLPC Light Modules feature a viewing angle of 170. LED FOR VLPC LIGHT MODULES The VLPC Light Modules feature LEDs with cool white color and temperature of 5000 K to 7000 K. The LED is packaged in a plastic package with integrated heat-sink and contacts. The LEDs used are based on the latest semiconductor technology thin InGaN technology. With thin InGaN, almost all the light is emitted from the surface of the emitter, eliminating typical loss from the sides of more traditional LEDs and boosting the efficiency. In addition, the conversion of the typically blue light is performed via a coating on the surface of the emitter unlike older technologies that depend on the phosphor in the lens. The LED chip is mounted directly on the heat-sink resulting in superbly low thermal resistance of 6 K/W typical, and ensuring a maximum life.
