LED traffic lights are fresh new substitute to traditional street lamps such as LPS, HPS, or MH street lights. LED traffic lights provide a multitude of advantages over conventional incandescent traffic lights. LED street lamps, LED street lights are environmentally friendly, energy efficient, and economical. This smart, "greener" option for outdoor lighting has emerged on the green scene due to the recent technological advancements of LED illumination.
Current enhancements include:
• luminous efficacy
• thermal management
• optical design
• color quality
• And.... COST
LED traffic lights consist of hundreds of tiny, electronic lights called LEDs (light emitting diodes). Several China companies and cities are in the process of replacing their existing HPS (High Pressure Sodium), LPS (Low Pressure Sodium), and MH (Metal Halide) light sources with LED systems because of these recent improvements. As a result of the rapid technological advancements made with this innovative, outdoor lighting system, there is no better time than the present to begin employing LED lamps on our roads, highways, parking lots and other pedestrian areas. By replacing conventional street lights with LED lamps, municipalities as well as organizations, will play a major part in the campaign for a cleaner, greener environment, and a brighter future for coming generations.
LED lighting fixtures will provide consistent benefits to the environment over time. Several benefits associated with replacing older traffic lights with LED lighting systems are:
• LED lights are brighter – because of increased luminance uniformity (the ratio of the maximum luminance to the average luminance within a specific area), and a higher color temperature, parking lots and roadways will benefit from advanced night visibility.
• LED street lights turn on immediately, without any delay.
• LED traffic lights are directional. This means their output is more even than that of other lamps. LEDs provide equal brightness across an entire surface and therefore are significantly brighter. For example, an HPS (High Pressure Sodium) lamp would need to throw a lot more light to get the same effect. Using an HPS light, a much larger light output would be a requirement.
• LED bulbs are environment friendly. LED light bulbs do not contain mercury, lead or other known hazardous material, to dispose of when the lights eventually burn out. Expended LEDs can be discarded without a disposal requirement or special handling. This results in cost savings both economically, and environmentally.
• LED lights consume less power. Expending less energy lowers greenhouse gas emissions such as carbon dioxide, which results in leaving a lower carbon footprint.
LED traffic lights will inevitably be the street lamps of the future.
