The Sparkle Behind Christmas Lights

Few things are more festive than the glow of Christmas lights. From elaborate outdoor displays to cosy indoor setups, these decorations are a seasonal staple. But what makes them shine so brightly? Let’s take a quick look into the history and inner workings of this holiday essential:?

The History of Christmas Lights: From Candles to LEDs?

The journey of Christmas lights began with candles. Before electricity, families would attach candles to their Christmas trees—a dangerous tradition prone to causing fires.??

This changed in 1882, when Edward H. Johnson, a colleague of Thomas Edison, created the first string of electric Christmas lights. His display of 80 coloured bulbs on a revolving tree set the stage for a safer, brighter tradition.?

By the 1890s, electrically powered Christmas lights became available, but their high cost restricted them to businesses and the wealthy. Mass production in the 1920s and 1930s made these lights affordable for the average household, further popularising the tradition.?

The advent of LED technology changed Christmas lighting forever. LEDs consume significantly less power, last longer, and are available in an array of colours and styles, from classic white to animated RGB displays.?

The Components Inside Christmas Lights?

Light Bulbs or LEDs?

Incandescent Bulbs: Older lights use filaments that glow when electricity passes through.?

LEDs: Contemporary lights use energy-efficient LEDs that emit light when electrons move through a semiconductor material.?

Wiring?

Insulated copper or aluminium wires connect the bulbs or LEDs in series or parallel circuits, protected by plastic coatings for safety and weather resistance.?

Resistors?

Resistors control the current, preventing bulbs or LEDs from burning out due to excessive power.?

Printed Circuit Boards (PCBs)?

Found in the more advanced programmable lights, PCBs contain components like microcontrollers to create dynamic light sequences.?

Controllers?

Controllers manage twinkling, flashing, or colour-changing patterns, often using microchips for pre-set programmes.?

Power Supply?

Plug-in lights use transformers to convert high-voltage AC to low-voltage DC power. Battery-powered lights include power regulation circuits.?

Connectors and Casings?

Weather-resistant connectors and casings protect outdoor lights from external damage.?

Fun Christmas Light Facts?

• The record for the most lights on a residential property is over 686,811 lights, set by a family in Lagrangeville, New York, in 2013.??

• NASA astronauts have reported being able to see large Christmas light displays from the International Space Station.?

• A car dealership in the Netherlands created a car dubbed ‘the most expensive Christmas tree in the world’: a Bugatti Chiron worth approximately €4 million covered in LED Christmas lights.?

• Universal Studios Japan, based in Osaka, holds the world record for the most lights on an artificial Christmas tree, at 612,000 lights. The theme park has been breaking its own record every year since 2011.?
