Led street lights and the difference between the traditional street lamp

Because of the traditional street lamps light source is used to light the mechanism of mercury vapor, therefore, the processing of waste light source is the problem urgently to be solved in the world today, at the same time, the traditional source of luminescence mechanism determines its harmful ultraviolet radiation. Led street lamp light source is a solid-state lighting, no harmful substances such as mercury elements, also won't emit ultraviolet, therefore, is a green light. In optical system, the traditional street lamp light source is omnidirectional light, half of the light is reflected by the reflector, the reflector is to absorb part of the light, so the light loss is larger. Due to the led road lights is a one-way light, the light utilization ratio is higher than the traditional street lamp. Traditional street lamps light distribution curve is determined by the reflector, and therefore has a certain limitation, and led street lamp light source is a kind of distributed source, through the design of the electric light source, make the light source of lamps and lanterns is the ideal bat wing, outdoor led street light by reasonable control the distribution of light, make the road flare rectangular, in the effective range, higher intensity of illumination evenness.
