Pay attention to the connection distance of the holiday decoration lights: Generally speaking, the connection distance of the holiday decoration lights of the festival decoration light series is 20 meters, and the connection distance of the 5050 series of holiday decoration lights is 15 meters. If the connection distance is exceeded, it is easy to heat up, and the service life will be affected during use. The glass tube can be colorless or tinted, and the inner wall can also be coated with phosphor.
Power connection: The general voltage of LED strip light is DC 12V, which needs to be powered by switching power supply. The size of the power supply is determined according to the power of the LED strip and the length of the connection. If you don't want each LED strip to be controlled by a power supply, you can buy a switching power supply with relatively large power as the total power supply, and then connect all the LED strip light strips into the power supply in parallel (if the wire diameter is not enough, it can be extended separately), and the main switching power supply is unified.
The city's silhouette during the day is defined by the shapes, colors, and shadows of the building's edges, and at night the city's festive lights clearly outline the city's silhouette, making it very different from the surrounding area. Looking at the city from a high vantage point at night, the silhouette is complete and clear, intuitively reflecting the shape and scale of the city. After the lamp part is vacuumed, it is filled with one or more inert gases such as neon, argon, helium, etc., and a small amount of mercury can also be filled.
Holiday Decorative Lights Lighting ProjectAccording to the color of the tubular glass, the nature of the phosphor and the filled gas, you can get a variety of holiday lights with different light colors. The festive decorative glass tube is equipped with copper electrodes at both ends, and its surface is chemically treated to prevent corrosion. The wires that are drawn from the electrodes and power supply are called leads, and they are required to have essentially the same thermal expansion characteristics as glass. In order to prevent glass breakage, nickel alloys are generally used.
