Light-emitting diode (LED) holiday lights are rapidly gaining popularity in many places due to their low energy consumption, long life and associated maintenance costs. Color LEDs produce light much more efficiently than their colored incandescent lights.
There are two types of LEDs: color LEDs and white LEDs. Regardless of the color of the transparent plastic lens that encapsulates the LED chip, the colored LED emits light of a specific color (monochromatic light). Plastics may be colored for aesthetic reasons, but do not substantially affect the color of the emitted light. This type of holiday light does not fade because it is determined by the LED chip rather than the plastic lens.
White LEDs are similar in most respects (such as power and durability), but use a two-stage process to produce white light (multi-color or broad-spectrum). In the first phase, the LED produces a color of light, similar to any other LED. In the second stage, some of the blue or purple blue is absorbed by the phosphor, which glows yellow, mimicking the many colors that people think are "white." This is essentially the same as a fluorescent light except that the LED is used to generate blue light instead of exciting the gas plasma to produce ultraviolet light.
White LEDs can be used as white holiday lights or to produce any other color by using colored refractors and lenses similar to incandescent bulbs. As with ordinary holiday lights, fading may occur due to exposure of colored plastics to sunlight or high temperatures. If the epoxy is always wrapped in epoxy, the epoxy may yellow in it.
Compared to incandescent lights, LEDs consume much less power (70 watts consume only 4 watts) and last longer. Since they are made of solid materials and no wires can burn or break, LEDs are less susceptible to breakage due to impact or rough handling.
Although LEDs are long-life devices, older or lower quality LED-based holiday lights can suffer from early failures. This is especially true for the latest blue and most expensive blue lights, so it is easy to cut costs. Most LED-based holiday lights use copper wire to connect to the copper-plated alloy leads of the LED. Contact with dissimilar metals can cause electrical corrosion inside the lightholder, causing them to stop working. Some older LED holiday lights permanently install each LED in a non-movable weathertight base to prevent moisture and help prevent such corrosion. However, this prevents the user from replacing defective lights.
Many small devices use a standard 3 mm dome-shaped LED with a plastic cover over it to provide refraction, which is an important step in diffusing the unidirectional light it projects. These covers are available in C5, C6 and C7 sizes (5⁄8, 3⁄4 and and inches, respectively, or diameters of 16, 19 and 22 mm respectively), with pointed ends of "strawberry" and G12 (12 mm or close to 1⁄2 inch) spherical" Raspberry" and "M5" (5mm or 7⁄32") pointed cylinders, equivalent to the T13⁄4 mini lights that have been very popular since the 1980s. For blue and green, these covers may fluoresce, resulting in color The other kits have a 5 mm dome with no cover because they project light in one direction. Instead, they have a tapered recess at the top to refract light to the side. There are other suits like snowflakes. (or Halloween, pumpkin) cover. There are also many LED screw-in bulbs to replace the real C71⁄2 and C91⁄4 bulbs, and the brightness is closer than the mini-imitation light.
