How much can a 50-watt high-power led street lamp replace now?

How many traditional street lamps can be replaced by 50-watt high-power LED street lamps?

Traditional street lamps generally use high-pressure sodium lamps or fluorescent lamps as light sources, and the power is generally between 150 watts and 400 watts. Because of high efficiency and energy saving, the power of LED street lamps is much lower than that of traditional street lamps under the same brightness.

The brightness of LED street lamps is generally measured by lumens (lm), while the brightness of traditional street lamps is generally measured by watts (W). According to the relationship between brightness and power of LED street lamps, we can roughly calculate how many traditional street lamps can be replaced by high-power LED street lamps with 50 watts.

First of all, we must determine the conversion relationship between the brightness of traditional street lamps and LED street lamps. Generally speaking, the brightness of traditional street lamps can be estimated by multiplying the wattage by the coefficient, while the brightness of LED street lamps can be estimated by multiplying the lumen by the coefficient. According to experience, the brightness coefficient of traditional street lamps is generally between 10 ~ 15, and that of LED street lamps is generally between 80 ~ 100.

Assuming that the brightness coefficient of traditional street lamps is 10 and the brightness coefficient of LED street lamps is 80, the brightness of 50-watt high-power LED street lamps can be estimated as 50 watts multiplied by 80, that is, 4000 lumens.

Then, it is necessary to determine the brightness requirements of traditional street lamps and LED street lamps. Generally speaking, the brightness of traditional street lamps is required to be between 5000 lumens and 10000 lumens, depending on the actual situation. Suppose the brightness requirement of traditional street lamps is 8000 lumens.

Finally, according to the proportional relationship between the brightness of LED street lamps and the brightness requirements, how many traditional street lamps can be replaced by high-power LED street lamps with 50 watts can be calculated. That is, 8000 lumens divided by 4000 lumens is 2.

Therefore, the 50-watt high-power LED street lamp can replace two traditional street lamps.

It should be noted that the above calculations are only estimates, and the actual situation may be different. In addition, the brightness and power of LED street lamps are also affected by other factors, such as the quality of LED chips and heat dissipation design. Therefore, in practical application, it is necessary to carry out detailed calculation and evaluation according to specific conditions.
