Answer: White LEDs are made by placing a yellow phosphorus coating over a 470nm blue
LED chip giving the white LED a cool white or florescent appearance.
Previously, the lack of white-light LEDs has limited the integration of LEDs
into a wide range of applications; however, now, the misconception exists that
InGaN-white LEDs can illuminate a lens of any color thereby simplifying lighting
requirements and designs. This is not completely true. Since the colors red
and green represent a very small part of the color scale in the white LED, white
LEDs should only be used behind a clear or milky white lens or panel. Place
white LED light behind a red lens and the light produced is a pink color, a
yellow lens turns a lemon-lime, green lens shifts to aqua and orange lens becomes
yellow. To maintain accurate and brilliant colors, it is imperative to match
the LED color with the lens color. In short, white LEDs made from a blue chip
should not be used as a general backlighting light source for different colored
lenses and panels. (more below diagram...)
With LEDtronics New Warm White LED you can now achieve the color rendering
that you require from behind different color lenses and panels with one warm
white LED.
These 3mm and 5mm 3200K White LEDs emit a warm incandescent-white light that
makes them excellent replacements for standard incandescent lighting. Architects,
entertainment designers and other lighting professionals will find that LEDs
100,000-hour life spans make LEDs ideal solutions for maintenance-intensive
and ornamental lighting applications.
LEDtronics offers 3200K LED lamps in many sizes ranging from 3mm midget flange
all the way up to 3.75-inch R30-style spotlights. What’s more, standard
electrical bases enable LED lamps to be integrated into existing wiring systems
without requiring modifications. Bases available are candelabra, 25mm Edison
screw, 15mm bayonet, wedge and flange. Also, 3200K Warm Incandescent-White LED
come in a variety of panel mount lamps and discrete (3mm, 5mm and SMT) LED packages.
LEDtronics Warm Incandescent-White LED lamps are available in all standard domestic
and international voltages.
