CHRISTMAS PROJECTOR LIGHTS SERIES

I used my own experience with Christmas light projectors to put together this list, having used them to decorate several homes in upstate New York. While some models are designed to withstand temperatures as low as 30 degrees below Fahrenheit, others are less robust, so make sure to check first before purchasing. Temperature Ratingĭepending on the climate, you should also make sure your projector will be able to stand up to moisture, as well as extreme temperatures. Or, if you’re a bit more adventurous and want something more fun and festive, consider a projector that can also generate images like Christmas trees and Santa Claus. If you’d prefer a more classic lighting scheme that looks the most like traditional Christmas lights, go with a model that uses lasers to create their lighting effect. The most important thing to consider when choosing a projector, is what you want projected. They work by projecting colored lasers or LEDs through colored lenses, and offer a variety of lighting effects and patterns. According to the (CPSD) Consumer Product Safety Division, there are about 200 injuries each day during the holiday season, and about half of them are decorating-related falls.Ĭhristmas light projectors are a convenient outdoor Christmas decoration, and do a great job of creating the festive atmosphere you want. Not to mention how dangerous it can be to access roofs and trees. Other popular holiday light trends include ombre (lights moving from one color to another seamlessly), oversized Christmas lights and geometric shapes.Hanging Christmas lights on your home and landscaping might be a holiday tradition, but it also takes a lot of time and energy to do correctly. It's important that consumers point these projectors directly at their homes, not at the sky.

When lasers hit airplanes, the pilot and other crew members may experience temporary blindness, headaches and watery eyes. In 2020, 6,852 laser incidents involving aircraft were reported to the FAA, compared with 385 in 2006. However, these projectors can disrupt air traffic if they aren't used properly. Holiday laser projectors are popular because they're easier to set up than string lights, especially when decorating rooftops. Unlike traditional projectors which use light bulbs, laser projectors use LEDs to produce the light. Here's how they work: Light is passed through a lens, which magnifies and displays a picture. When these projectors are pointed at a house, they create special effects like falling snow or flying reindeer. LED lights have also allowed the use of laser projectors in holiday light décor. They also come in a variety of shapes and styles.

An LED bulb may last 50,000-200,000 hours while the incandescent bulb will burn for 3,000 hours.Īn added benefit is that these lights are often programmable, allowing users to change the color of the lights and select different blinking modes. For instance, 10 strings of incandescent mini-lights would burn 408 watts, but the same strings of LED lights would only burn 4 watts. Capitol and Rockefeller Center had been lit using only LED lights.Įven though they cost consumers more upfront, LED lights use 80 percent less energy and last much longer than traditional incandescent lights. The first LED Christmas lights were sold in 1998, and by the early 21st century, Christmas trees at both the U.S. When an LED bulb fails, it typically short-circuits, so the rest of the string can work even in the absence of a shunt.

LEDs are wired in a parallel series like incandescents, but they don't use shunts. The result is the visible light we see in an LED. When an electron and an electron hole collide, a small amount of energy is released as a photon.

On the positive side, particles called “electron holes” move toward the negative side.

When current is applied to the system, electrons from the negative side move toward the positive side. A diode consists of something called a p-n junction - two semiconductor materials next to each other, one with a positive charge (p) and one with a negative charge (n).
