Led street light vs high pressure sodium Lamp
LED street light is a new type of street light, which adopts the most advanced LED technology. LED street light has the advantages of energy saving, high efficiency, long life, and environmental protection, which is ideal to replace traditional street light.
What is an LED street light
LED streetlights are a type of streetlight that uses light-emitting diodes (LEDs) as the light source. These streetlights are typically more energy efficient, durable, reliable, easier to maintain, and longer lasting, and are therefore considered a good choice over traditional fluorescent and sodium lamps in many applications. LED streetlights typically have faster start-up times, longer service life, and more consistent spectral quality than conventional streetlights.
The advantages of LED street light
LED street light is energy-saving. Compared with traditional sodium or iron pressure lamps, LED street lights consume much less energy and can save more than 80% of energy. At the same time, the luminous efficiency of LED street lights is also higher, which can improve the light level of street lights and provide people with a more comfortable environment.
LED street lights are highly efficient. LED street lights have a very high luminous efficiency, which can improve the illumination of street lights. At the same time, the luminous color temperature of LED street lights can be adjusted as needed to provide people with a more natural and comfortable light.
LED long life, the general life of LED street lights can reach 100000 hours, which is much longer than the life of traditional incandescent and sodium lamps.
High protection grade
In addition, LED street lights are also waterproof and dustproof, they can be better adapted to the outdoor environment, which is a major advantage for traffic routes and urban construction.
Parameter comparison of LED street light and HPS
|Types||250W HPS||100W LED street light|
|Application Range||Roads, Street, Highways||Roads, Street, Highways|
|CCT||3500K||2200K-6500K for optional|
|CRI||CRI 30||CRI 70|
|Spectrum||UV-driven, spectrum contains UV||No UV, no harm to skin|
|Light Flicker||High pressure high frequency drive with flicker||DC drive, no flicker|
|Light decay||3000 hours 30%||100000hours<30%|
|Luminous flux||The efficiency of the lamp is low, the loss of luminous flux is large, and the effective luminous flux is small||High lamp efficiency and high effective luminous flux|
|Operating conditions||Low temperature and low pressure is difficult to start, warm light time of 15 to 20 minutes||Small environmental dependence, low current drive, no warm light time|
|Light distribution design||The structure of the reflector determines the type of light distribution, and the type of light distribution is less||Through optical lens to achieve the spectrum, a variety of optical lenses optional|
|Environmental protection||Contains mercury and heavy metals||No pollution|
|Safety||High temperature and high pressure is not safe||Low temperature and low pressure is safe|
|Lifetime||5000-10000 hours||＞100000 hours|
|Total power consumption||300W||100W|
|Actual power consumption||250W||90W|
Cost comparison of LED street light and HPS
High-pressure sodium and LED streetlights may have slightly different costs at the time of purchase, but in use, LED streetlights are usually more energy efficient and therefore may be more cost-effective. High-pressure sodium lamps typically have a shorter bulb life than LED streetlights, so LED streetlights may be more cost-effective for long-term use. However, this all depends on your specific situation. It is recommended that you consult with a professional to understand the electricity usage in your area and to do the relevant cost calculations to make a better decision.
Here you can simply show the electricity consumption of the two lamps in the case of the same brightness, generally, a 100W LED street light can replace the 250W high pressure sodium lamp.
High pressure sodium lamp efficiency is relatively high, taking 95% to calculate.
The efficiency of LED streetlights is almost 85%.
A day according to 10 hours of light time
Sodium lamp electricity consumption a year = (250/0.95*10*365)/1000 = 960.5 KWh
LED street light electricity consumption in a year = (100/0.85*10*365)/1000 = 429.4 KWh
Why choose ZGSM LED street light？
After understanding the basic situation of both lights, I believe we will choose the LED products for our lighting use. ZGSM, as a top outdoor lighting manufacturer in China with nearly 20 years of lighting design experience, I would like to recommend our new LED street light, the Halo series intelligent street light.
Halo series LED street lights can be equipped with an intelligent control system, which can automatically adjust the brightness and switch according to the light intensity, traffic flow, and other information to improve energy use efficiency and reduce energy consumption. The intelligent street lights can also be remotely monitored and managed through the Internet or wireless communication networks to improve the reliability and safety of the lighting system.
