Case study: solar street lamps compared with ordinary street lamps, light emitting diode

1, electricity contrast: use 60 w LED street lamp of charge of electricity of a year to produce, only for the use of ordinary high pressure sodium lamp 250 w street light year 20% of generate electricity, greatly saves electricity costs, is the ideal energy saving products, also complied with the trend of the construction of economical society.

1, electricity contrast:

use 60 w LED street lamp of charge of electricity of a year to produce, only for the use of ordinary high pressure sodium lamp 250 w street light year 20% of generate electricity, greatly saves electricity costs, is the ideal energy saving products, also complied with the trend of the construction of economical society.

2, laying cost compared to

the LED street lamp power is a quarter of ordinary high pressure sodium lamp lights, laying copper cable sectional area required for ordinary street lamp only a third, saving the cost of laying.

the above two to save costs, using the LED street light than using normal high pressure sodium lamp lights, the former can make the owner back within a year early increase the cost of inputs.

3, illuminance contrast:

use 60 w LED street light can reach 250 w high pressure sodium lamp illumination, greatly reduces the use of power; Low power LED street light for its use, it can be combined with wind, solar, use time on the road in the city.

4, using temperature contrast:

than ordinary street lamp, LED street light in use process of low temperature, won't produce high temperature continuous use, not black not black chimney.

5, the safety performance contrast:

cold Yin lamp, electrodeless lamp on the market at present, are all inspired by high pressure point X light illumination, toxic metals such as hg, and harmful rays; By contrast, LED lights are safe low voltage products, in the process of installation and use greatly reduces the potential safety hazard.

6, environmental performance contrast:

ordinary street lamp containing harmful metals, spectrum contains harmful rays. , by contrast, the LED street light spectrum purity, contains no infrared and ultraviolet (uv), no radiation, no light pollution, and do not contain harmful metals, waste recycling, belongs to typical green lighting products.

7, compared with the quality of life:

the average service life of the ordinary street lamp is 12000 hours, the lights change not only cost is high, and affect the traffic, especially in places such as tunnel construction inconvenience; The average life span for the LED street light for 100000 hours, according to the meter using 10 hours a day, service life for ten years, once and for all. In addition, the LED street light waterproof, impact resistance and shock are good, stable quality, the warranty period is a maintenance free product.
