Q: The same brand of chips, how to judge the quality of LED lights?: To see what the main power supply under the lamp, cross flow or constant voltage, power supply and general outdoor lighting brand, with the meanwell mosopower

Q: Energy saving control of street lamps can save energy?: Single lamp installed variable power ballast: this measure is to install a power ballast can transform in each high pressure sodium lamp, with the same, at 12 o'clock in the morning, on the road almost no vehicles and pedestrians in the low traffic roads still maintain a high intensity apparently is not necessary. But some roads are not suitable for the implementation of the night lights lit, then can use the variable power ballast, low in road traffic flow, appropriate to reduce the power of the bulb, the bulb 50% to 60% at rated power, when the lamp power while reducing from 40% to 50%, but the road illumination only reduced 30%. Can guarantee the road traffic safety requirements. But even in the midnight voltage increases when the overload phenomenon does not appear light bulb and ballast, which not only can save a lot of power, but also can prolong the service life of the bulb and ballast lamp, which saves a lot of maintenance costs.

Q: Method for connecting cable between street lamp and street lamp: Is now widely used in the whole cable wear, probably set aside from not less than 700mm, and will open in the middle, take a zero, a fire, a head, throw to the power on the street where. Pay attention to three-phase matching.This is safer and increases the installation speed considerably. It takes time to make a cable head.

Q: What qualifications does LED street lamp product need? Do you need 3C certification?: 3C certification is called "mandatory product certification system", it is the governments to protect consumers' personal safety and national security, enhance product quality management, in accordance with the laws and regulations the implementation of a product conformity assessment system.

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: 400W high pressure sodium lamp can replace 150WLED lamp? Luminous flux?: Yes, and under the current technical conditions, the life expectancy of HPS is much longer than that of LED street lamps

Q: How long does the general power LED power supply cycle last? Such as street lights, power supplies, 150W, 180W?: See what voltage input, what are the requirements?.If it is me, usually 40 days to get the prototype. 220V input, 56V, 3a out. Without special requests.

Q: What is the reason that the longer the wire pulls on the LED street lamp, the lower the voltage?: Wires have resistances. The longer the wires or wires, the smaller the resistance, the greater the resistance.

Q: What heat sink is best for LED street lamp radiator?: Is natural heat dissipation, what is called natural heat dissipation, that is, rely on the lamp's own radiator to dissipate heat, and now most of the market is fin type heat sink, this advantage lies in the cost point, passive heat dissipation time. However, the disadvantage is that the heat dissipation is very slow, far less than the high-power heat dissipation requirements. Good service life is less than 2 years. But recently, the market has a kind of through-hole type heat radiation lamp, break the traditional heat dissipation concept, increased the heat dissipation surface, let the air form convection. The cooling effect is remarkable. You should be interested in discussing LED lighting technology, so you can leave a contact. I'm technical. Hope to be adopted

Q: How is the minimum illuminance of LED street lights Emin obtained? How to calculate?: If you want to measure the value, I can only say that the approximate, because the illuminance value on a point value, the actual measurement is the target area is divided into small areas of uniform, center to measure each region with the value of the measured value, there is a minimum value.
