LED street lights to replace traditional incandescent

Can be said that the current state of development, LED bulbs can’t be maintained, the event of a failure, only the replacement of lamps, in addition to high costs, but also greatly extended the time to maintain, this unit is very much on the use of unfavorable.

Maintenance of the light source, high pressure sodium lamp to more easily be replaced in the field directly to electrical light source, and lower cost. For LED bulbs, I think, that is LED bulb light manufacturer, so the on-site maintenance can’t be carried out.

LED street lights distribution problem is the LED street light with optical technology has made significant progress, some manufacturers have developed a system of secondary distribution of light instead of relying solely on-chip array to go with light, but the broad view, light distribution can’t be entirely reasonable, I have observed a lamp, with the road side is brighter, uniformity also meet the requirements, but significantly less than the sidewalk side of brightness, SR value is clearly not meet the requirements.
