Discussion on the application of high power LED street lamp

In recent years, the domestic LED lighting applications developed rapidly, many manufacturers have launched a high-power LED street lamp, and as more and more applications in road lighting energy-saving products, in the high-power LED street lamp can really replace traditional light source (mainly the HPS)?

First, on the LED street lighting effect, in the case of a lot of practical LED street lamps to replace high pressure sodium lamp, power saving is an important factor, but the actual LED street lamp is not less than the high-pressure sodium lamp. From the comparison of luminous efficiency, luminous efficiency of high power LED lamps at the practical application (80lm/W) is far lower than that of high pressure sodium (100~138lm/W), while LED is a directional light, light efficiency is higher than that of high pressure sodium lamp, but as the light emitting efficiency, LED street lamp comprehensive energy efficiency or low to high pressure sodium lamp.

In some LED street lamp to replace the high-pressure sodium lamp to obtain energy-saving effect in the case, according to the analysis, the case is often the original power (high brightness lamp or lamps serious exceed the standard) low efficiency, light attenuation serious state, as the LED street lamp is not scientific basis.

Color two, LED lights, the high-power LED street lamp basically is to use 5000K~6000K color temperature of white light, as road lighting source in the visual feel too cold, but when the eyes hyperopia observation ability will decline, that some research in this area, low in 3000K yellow light or white light is relatively warm suitable for road lighting, so LED lamp is not suitable for daylight lamp utility.
