High frequency jet lamp, LED lamp, xenon lamp, which is suitable for street lamps
The so-called high frequency jet lamp, according to my observation, should be ceramic metal halide lamp, just ballast working mode and the previous adjustment, it may also be manufacturers just make a gimmick.To do street lights, the current high-pressure sodium lamp and LED lights are more, but if the local highways department can pass, it is recommended to adopt 150W or 250W ceramic metal halide lamp, but the quality of supporting ballast must be reliable.
High pressure sodium lamp light control, high luminous efficiency, long life, high color, the color is very suitable for 4000K~5000K lamps, but a relatively small enterprise effort in developing high performance and stability of the ballast, on the other hand, because of government support for the LED industry, so its application in the street did not get attention and promotion proper.
LED light color and soft, to capture and analyze details of road condition eye to night lighting, but due to the LED light emitting chip is heat sensitive, so the steady flow module and a heat dissipation module as big and complex, weight big, cost is very high, but from the actual situation, life did not claim so long. Even the shortest in several light sources. Many places use this as a source of care for the local light source industry.
Here to analyze the advantages and disadvantages of several light source: high pressure sodium lamp has high efficiency, long life, light penetration, rain and fog irradiation range is relatively secure, but a single color spectrum, low resolution, according to details of poor road.
