Technology Of LED Holiday Light

  • Light-emitting diode (LED) holiday lights are rapidly gaining popularity in many places due to their low energy consumption, long service life, and low maintenance costs. The luminous efficiency of color LED is much higher than its color incandescent light.

    There are two types of LEDs: colored LEDs and white LEDs. Regardless of the color of the transparent plastic lens encapsulating the LED chip, the color LED emits light of a specific color (monochromatic light). Plastic may be colored for decorative reasons, but it does not substantially affect the color of the emitted light. This type of holiday light does not fade because the light is determined by the LED's chip rather than the plastic lens.

    White LEDs are similar in most aspects (such as power and durability), but utilize a two-stage process to produce white light (multicolor or broad spectrum). In the first stage, the LED produces one color of light, similar to any other LED. In the second stage, some blue or violet blue is absorbed by the phosphor, which emits yellow light, mimicking multiple colors that are considered "white". This is basically the same as fluorescent lights, except that LEDs are used to generate blue light instead of exciting gas plasma to generate ultraviolet light.

    White LEDs can be used as white holiday lights, or any other color can be produced by using colored refractors and lenses similar to incandescent bulbs. Like ordinary holiday lights, exposure to sunlight or high temperatures can cause discoloration of colored plastic. If the epoxy resin is always wrapped in the sun, yellowing may also occur in the epoxy resin body in which the LED is encapsulated.

    Compared to incandescent lights, LEDs consume much less power (70 light strings consume only 4 watts) and have a longer life. Because they are made of solid materials and no wires will burn or break, LEDs are less likely to break due to impact or rough handling.

     

    Although LEDs are long-life devices, older or lower-quality LED-based holiday lights may suffer from early failure. This is especially true of the latest blue and most expensive lights, making it easy to cut costs. Most LED-based holiday lights use copper wires to connect to the copper-plated alloy leads of the LED. . Contact with dissimilar metals can cause galvanic corrosion inside the lightholders, causing them to stop working. Some older LED holiday lights permanently installed each LED in a non-removable, weather-tight base to prevent moisture from entering, helping to prevent such corrosion. However, this prevents users from replacing defective lights.

    Many small devices use a standard 3mm dome-shaped LED and have a plastic cover over it to provide refraction, an important step in diffusing the unidirectional light it projects. These cases are available in C5, C6, and C7 sizes (⅝, ¾, and 分别 inches, respectively, or 16, 19, and 22 mm in diameter), with "strawberry" tips, and G12 (12 mm or close to ½ inch) spherical " "Raspberry" and "M5" (5 mm or 7⁄32 inch) pointed cylinders, equivalent to the T1¾ mini lights that have been very common since the 1980s. For blue and green, these covers may fluoresce, causing The colors are lighter. Other kits have a 5mm dome without a lid because they project light in one direction. Instead, they have a tapered notch at the top to refract light to the sides. There are other kits like Snowflake (or Halloween, pumpkin) cover. There are also multi-LED screw-in bulbs to replace the real C7½ and C9¼ bulbs, and the brightness is closer than the mini imitation lights.
