As high-power LEDs are commonly used in lighting decoration and lighting, power LED drivers are becoming more and more important. It is possible to use high-power LED lighting for road lighting. Road lighting is the longest used and most power-consuming lamp. The use of LED lights in street lamps will greatly reduce the city's power shortage and save the national energy.

Since the street lamps are all horizontally inserted, LEDs can only be used to make one-sided illumination, but only need to adjust the position when the bulb is installed, and the illumination effect is not affected. The power of the street lamp is divided into 20W, 30W, 40W, 50W with high-power LED, long service life and maintenance-free. Since the LED consumes less power, has a lower voltage, and has a smaller current, the cross section of the installed cable is correspondingly reduced, thereby saving installation costs.

A complete road lighting system consists of a light source, a cable, and a power supply system.

First, the comparison of LED street lights and traditional street lights

Suppose a city has three sections of road lengths of 3 km, 5 km, and 10 km respectively. The street lamps are laid every 30 meters, and each side is calculated. The total number of street lamps required for these three sections is 202, 33. 66, the traditional street lamp is based on the high-pressure sodium lamp with a power of 250W, and the LED street lamp is based on the power of 50W.

The traditional street lamp has a unit price of 1000 yuan, and the LED street lamp has a unit price of 3000. The cost of the light source for the three lengths of traditional street lamps is 202*100=20200 yuan, 333*1000=333000 yuan, 666*1000. =66600 yuan, the cost of light source for laying three kinds of roads with LED street lights is: 202*300=606000, 33*300=99900, 66*2 00=1998000

Second, the comparison of the cost of LED street light and traditional street light cable

Let's analyze the cost of laying cables for two types of roads with three lengths of roads. The load flow of traditional streetlights for 3 km roads is I=P/U=202*250/220=230A, which requires a copper core with a cross-sectional area of 60 mm2. Cable, its unit price is 120 yuan / m, then its cable cost is 120 * 3000 = 360,000 yuan, LED street light trunk cable load flow l = P / U = 202 * 50 / 220 = 44A, it needs a cross-sectional area of 1Omm2 Copper core cable, which requires a copper core cable with a cross section of 12mm2, the unit price is 12 yuan / meter, the cable cost is 12 * 300 = 36,000 yuan, 5 km road traditional street lamp main line cable load flow I = P / U = 333 *250/220=377A, it requires a copper core cable with a cross section of 90mm2, the unit price is 180 yuan / m, the cable cost is 980 * 5000 = 900,000 yuan, LED street light trunk cable cable load flow I = P / U = 333 *50/220=73A, it requires a copper core cable with a cross-section of 20mm2, the unit price is 25 yuan / piece cost is 25 * 5000 = 125,000 yuan, 10 km road traditional street lamp main line cable flow I = P / U = 666 *250/220=680A, it requires a copper core cable with a cross section of 400m2, the unit price is 360 yuan / meter, the cable cost is 360 * 10000 = 3.6 million yuan, LED street light trunk cable load flow I = P / U = 666 *502 20=146A, it requires a 42mm2 copper core cable with a unit price of 60 yuan/meter and a cost of 600,000 yuan.
