Production and marketing of LED street light in the future

With the speeding up of urbanization, street lamp manufacturers already entered people's vision, now, the streets of major cities, LED street light can be seen everywhere, it decorate the night sky of the city. But it still didn't get the use of the most abundant, because its nothing but also

 with the speeding up of urbanization, street lamp manufacturers already entered people's vision, now, big city' Refers to the economy more developed, population is concentrated political, economic and cultural center. 】 The streets of, LED street lamp LED street lamp is made of street lamp, LED lamps and lanterns with high efficiency, safety, energy saving, environmental protection, long service life, fast response speed, high color rendering index of unique advantages, the city lighting energy saving is of great significance. 】 Can be seen everywhere, it decorate the night sky of the city. However, it still didn't get the use of the most abundant, also there will be no more than because their limitations. In order to ensure that the LED street lamp can play more role in our day, produce in the future research and promotion use, we should deal with these problems first: the appearance of lamps and lanterns structure problem. The appearance of traditional street lamps and lanterns is basically the same, generally divided into light source and electrical parts, but due to the LED light source' LED light source is the light emitting diode ( 领导) For light source of light. 】 Particularity and light distribution method is different, now makes the appearance of LED street lamps and lanterns is varied, during which a lot of shape of lamps and lanterns is not satisfied with the requirement of the operation, some companies are even indoor specification applied in the field street lamp. Second: there was a problem with the connection of LED lamps and lanterns and light pole. Now, almost all the LED lights are fixed screw positioning, few coupling bolt. So, there is a great danger over the safe operation of lamps and lanterns. The limitations of LED street lamp itself to limit its to carry out the third: parts of lamps and lanterns of replaceability problem. LED street lamp parts generally have LED chip, the power supply ( Drive) And the shell parts of lamps and lanterns. Easy to bad parts mainly power and chip. In general, the LED lamps and lanterns of chip is electronic radiator 【 Electronic radiator is usually for high-power electronic cooling heat sink, no additional power supply, natural cooling. 】 Can't replace, and the power supply ( Drive) Replaceable, however, it is where there are many products in the power supply ( Drive) Also not convenient, on the replacement of replacement is too time consuming. And it is well known, LED lamps and lanterns stature can now reach 3 - 50000 hours. If can't replace the LED chip, that means replacing the lamps and lanterns, also can form. The fourth is the power ( Drive) The measure problem. Power supply ( Drive) Is now LED lamps and lanterns is very critical parts. Now on the market are generally not only to ensure the quality of the LED chip and power supply ( Drive) The measure is another matter. On general manufacturer committed to 2 years. It is in the final analysis because, LED street lamp development met new bottleneck - power supply ( Drive) Not to ensure the quality of the, it limits the LED street lamp. LED street lamp power saving effect. Saving electricity in theory, but practice on the LED street lamp is no better than that of high pressure sodium lamp power saving. Under the premise of lighting quality specification, high pressure sodium lamp high-power lamp ( 250 ~ 400 w) Smooth effect, can reach 130 ~ 1 140 m/W. And 1 w high power LED street light much LED tube, the photosynthetic efficiency and high voltage sodium lamp is similar, but considering the ballast loss, lamps and lanterns and light power usage three elements, such as induction, now LED lower efficiency than the high-pressure sodium lamp. And small power LED street light, ≤150 w) 10% energy saving than the high-pressure sodium lamp.
