Q:What are the main uses of LED street lamps?: Street lights must be used on highways, such as roads, highways, urban roads, parks and so on

Q:LED Street pressure is not enough, what will happen?: Potential safety problems, resulting in shortened service life, serious damage to the product directly.

Q:Why does fog cause fog when the LED street lamp is aging?: The outside gas is in, and it's designed to be self breathing.

Q:How many watts does the LED street light have?: The technology is mature day by day, and the high-power LED light source can meet the needs of general street lamps. The general optical efficiency of high pressure sodium lamp is 100LM/W, high power LED is commonly used by foreign 50-60LM/W, the best LED chip can reach 80LM/W, the luminous efficiency is high, means that the energy saving effect is better, which is the choice of one of the most important indicators of LED street lamp. However, the LED standard does not specify this, so the purchase of LED street lamps must be carefully confirmed.

Q:How many lights can a high-power LED lamp be at least W?: High power LED street lamp, as the name suggests, is a single power greater than 1 watts, using a new type of LED semiconductor light street lamps. At present, the standard of LED street lamps is generally the average illuminance of (uniformity of road surfaceilluminance), which is greater than 0.42 of the national standard. The spot ratio is 1:2, which conforms to the illumination of the road. The actual 1/2 center spot reaches 25LUX, and the 1/4 center light intensity reaches 15LUX, the minimum light intensity is 4LUX at 16 meters, and the overlap light intensity is about 6LUX.

Q:Who knows LED street lamp warm white light and positive white light have what difference, how should choose?: Because the light intensity of the human eye light is higher than that of the warm white light, the naked eye will feel that the white light is brighter than the warm white one.

Q:What are the standards for LED street lighting?: Light efficiency, the good light theory is 100lm/W, 100 watt incandescent lamp is about 1200lm, that is to say, about 12W LED lamp luminous flux is equivalent to a 100 watt incandescent lamp, this is the origin of energy saving. Of course, in fact only theory, but also the specific consideration of power loss of LED, loss and attenuation of photothermal divergence, and so on, is not to say, here is not to write.

Q:What is the starting current of the LED street lamp for 220V and 30W?: But the influence is very small, so it can be considered as the starting current is the rated current, and the rated current = power / voltage = 30/220 = 0.136A

Q:How to select suitable driving power for LED street lamp: LED lamp driving power supply for outdoor work, poor environment, the temperature variation of four seasons a year, the summer sun, winter cold, but also accept the rainstorm, lightning shock, so all kinds of tolerance need to be considered.

Q:How big wires should fifteen LED street lights require?: This is to see how much power each LED lights, you can ask Hubei Ling photoelectric, they specialize in LED street lamps
