Connection distance of festive LED decorative lights

Pay attention to the connection distance of holiday LED decorative lights: Generally speaking, the connection distance of holiday decorative lights of the holiday decorative lights series is 20 meters, and the connection distance of 5050 series of holiday decorative lights is 15 meters. If the connection distance is exceeded, it is easy to generate heat, which will affect the service life during use. The glass tube can be colorless or colored, and the inner wall can also be coated with phosphor.

LED decorative light power connection method: The general voltage of the LED light strip is DC 12V, which needs to be powered by a switching power supply. The size of the power supply is determined according to the power and connection length of the LED strip. If you don’t want each LED light strip to be controlled by one power supply, you can purchase a switching power supply with relatively high power as the total power supply, and then connect all the LED light strip input power supplies in parallel (if the wire diameter is not enough, you can extend it separately), the main switching power supply Unite.

The daytime city silhouette is defined by the shape, color and shadow of the building edges, and at night the city's festive LED decorative lights clearly outline the city's silhouette, making it distinct from the surrounding areas. Looking at the city from a height at night, the silhouette is complete and clear, which intuitively reflects the shape and scale of the city. After the lamp tube is partially evacuated, 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.

According to the color of the tubular glass, the nature of the fluorescent powder and the filling gas, you can get a variety of holiday lights with different light colors. The festive decorative glass tubes are fitted with copper electrodes at both ends and are chemically treated to resist corrosion. The wires drawn out from the electrodes and the power supply are called leads, which are required to have basically the same thermal expansion characteristics as glass. In order to prevent the glass from cracking, nickel alloys are generally used. Glamor
