Christmas lights are a beloved holiday tradition, bringing joy and sparkle to homes and neighborhoods each winter. In recent years, LED (light emitting diode) Christmas lights have become increasingly popular. LEDs use much less electricity and last much longer than traditional incandescent Christmas lights. Multi color LED Christmas lights take the technology a step further, allowing for dynamic and customizable lighting displays.
How LEDs Work
LEDs are semiconductor devices that emit light when an electric current passes through them. An LED consists of two parts – a chip of semiconductor material doped with impurities to create a p-n junction, and a plastic lens to focus the light. When voltage is applied to the semiconductor, electrons can recombine with electron holes within the device, releasing energy in the form of photons or light particles. The color of the emitted light depends on the semiconductor material used.
Early LEDs could only emit low-intensity red light, but over time researchers developed methods to produce brighter LEDs in different colors. Blue and white LEDs were a major breakthrough that paved the way for LED lighting. LEDs offer many advantages over incandescent bulbs – they last much longer, are more energy efficient, durable, and compact.
Multi Color LEDs
Multi color LED Christmas lights take advantage of innovative LED technology to create colorful, customizable holiday displays. There are two main types of multi color LED Christmas lights:
- RGB LEDs – These contain red, green, and blue LED chips in each bulb. By combining different levels of intensity from each LED, RGB bulbs can produce a full spectrum of colors.
- Single color LEDs – These strings contain individual LED bulbs in a variety of colors, such as red, green, blue, yellow, orange, purple, and more.
Within each LED bulb, there are generally several small LEDs or chips mounted together. Wiring connects each LED to a microchip controller. The controller manages electricity to each LED to produce different colors, effects, and animations.
Wiring and Controllers
Let’s take a closer look at how multi color LED Christmas lights are wired and controlled.
Wiring
LED Christmas light strands use low voltage direct current (DC) wiring. Within each light string is a pair of parallel wires. One wire connects to the positive side of an LED and the other to the negative side. When DC voltage is applied, electricity flows through the semiconductor material and light is emitted.
Here are the main wiring components in multi color LED strands:
- Direct current (DC) wiring – conducts electricity through the string
- LED bulbs/lamps – emit light when current flows through
- Rectifier – converts AC input to the required DC output
- Controller – manages color, effects, animations
- Plug connector – connects light strand to electricity source
Controllers
The controller is the “brain” of multi color LED Christmas lights. Controllers can be built into plugs or separate control boxes. They may have buttons, dials, or apps to control various settings and effects. Here are some of the functions multi color LED controllers perform:
- Converts AC input to the required DC output for LEDs
- Controls electricity flow to each LED
- Changes LED colors by adjusting current to red, green, and blue elements
- Operates built-in lighting effects like fades, flashes, and chases
- Stores memory settings and recall preferred colors/effects
- May allow wireless app or voice control
Higher quality LED controllers offer more effects, color options, and convenient controls. Basic controllers may just have a few buttons to toggle between colors and effects, while advanced options allow millions of colors and programmable shows.
LED Christmas Light Types and Features
There are many styles of LED Christmas lights available to meet different decorative needs. Here are some of the most popular types and features.
Miniature Bulbs
Mini or micro LEDs are very small bulbs, about the size of a grain of rice. They are popular for Christmas trees and detailed decorating. Mini LEDs allow for dense, brilliant lighting displays.
C7 and C9 Bulbs
These mid-size bulbs have a candle flame shape and mimic the look of classic incandescent Christmas lights. C7 bulbs have a diameter of 7/8th inches. C9 bulbs are a bit larger at 1 1/4 inch diameter. Both C7 and C9 LED bulbs are versatile options for all types of Christmas decor.
Icicle Lights
Icicle lights contain a series of LED bulbs mounted in a dangling wire, designed to look like hanging icicles. They nicely illuminate trees, rooflines, and outdoor landscapes.
Rope Lights
These lights use tiny surface-mount diodes encased in a flexible plastic rope. Rope lights are very flexible and can accent railings, pathways, trees, and decorative props.
Shaped Lights
Multi color LEDs can also be mounted in decorative light shapes, like snowflakes, stars, or candy canes. Shape lights enhance displays with custom silhouettes and color effects.
Lighted Decorations
LED technology allows for all kinds of lighted Christmas decorations, from trees to wreaths to Santa suits. String lights can be embedded into almost any decoration for customizable color effects.
Programmable Controllers
Higher-end LED controllers include programmable features for custom light shows. Users can create and save unique sequences of colors, effects, timing, and animations.
Smart/App Control
Some advanced LED Christmas lights sync with smartphones or tablets, allowing users to easily control lighting displays through an app. Smart displays can be programmed and synced to music.
Power Options
LED Christmas lights are available in both plug-in and battery-powered options. Battery packs make decorating easy without dealing with outlets and extension cords.
Creating Custom LED Lighting Displays
The possibilities for creating custom LED light shows are nearly endless thanks to the flexibility of multi color bulbs and programmable controllers. Here are some tips for building an amazing programmable Christmas light display:
- Map out a lighting zone plan for your home and yard to designate areas for different colors and effects.
- Buy a programmable controller and high density LED lights to maximize effects.
- Use mini lights for trees and bushes; rope lights and C7/C9 bulbs for outlining.
- Incorporate some smart decorations like lighted wreaths, arches, and shapes.
- Use lighting animation software to program and sync your display to music.
- Save your programmed sequences to memory cards for each season.
- Add power extension cords and repeaters to boost signal strength as needed.
With a well-planned display and top-notch LED lights, you can deck your halls with dazzling color effects and lighting magic this holiday season. Programming capabilities make it easy to customize shows to your liking.
LED Christmas Lights Comparison Table
Here is a helpful comparison table summarizing some of the different LED Christmas light options:
| Light Type | Shapes and Sizes | Best Uses |
|---|---|---|
| Miniature | Rice grain sized bulbs | Christmas trees, wreaths, detailed decor |
| C7 | Candle shape; 7/8″ diameter | Outlining eaves, railings, windows |
| C9 | Candle shape; 1 1/4″ diameter | Outlining rooflines, fences, etc. |
| Icicle | Dangling, icicle shaped lights | Hanging from roofs, trees, etc. |
| Rope | Tiny LEDs in a plastic rope | Wrapping columns, trees, banisters, etc. |
| Shaped | Snowflakes, stars, candy canes | Adding custom accents and colors |
Conclusion
Multi color LED Christmas lights are a fun way to deck out your home in spectacular holiday style.
