Q:Why does a LED street lighting system come with a phase light?
Because the LED light current is in the Ma level and slightly leaks, the current will shine.
Q:How many kinds of power do LED street lights have? How much brightness can it replace the high pressure sodium lamp? What kind of power does the general main road need?
Generally have 20W, 30W, 50W, brightness can be replaced by 100W, 150W, 200W power high-pressure sodium lamp 30W~50W power is enough for a common trunk road.
Q:Is the price of the street lamp factory in led the same?
The price of street lamps at the LED street lamp factory is the same as that of the foreign ones. LED street lamp external price = cost + profit. The cost is fixed, that is, profits will change, in addition to street lamps manufacturers require profits, the salesman will be appropriate adjustments, this depends on the salesman personally
Q:LED street lamps must be constant flow source? No constant current source, can I?
No, I think the LED street lamp needs DC power supply.
Q:What is the distance between the usual street lights?
60 watt LED lamp holder, about 6 meters light pole, 15-18 meters apart; 8 meters light pole is spaced at 20-24 meters, 12 meters, the lamp post is 32-36 meters apart. Data is for reference only.
Q:Why is the higher the current, the lower the light efficiency?
Because the higher the current, according to Ohm's law, of course, the power will also increase, while the luminous efficiency is the total luminous flux / total power
Q:What is the problem of flashing LED street lights on the side of the road?
Check whether the current limiting resistor in the circuit has changed, or whether the current of the power supply is off the rated value. If it's a different LED flash, it's a LED quality problem that needs to be replaced.
Q:How many volts is the 42wled solar street light?
Usually less than 15 watts of courtyard lights are 12 volts, and then small is a few watts of lawn lights, is 3.6 volts.
Q:LED street lights are different from high pressure sodium lamps (both street lamps), as well as superior power consumption
The color temperature of LED street lamp is high, the color rendering is very good, the visual effect is better than that of sodium lamp. In theory, it saves electricity and lives longer than the high pressure sodium lamp, and the luminous efficiency of high pressure sodium lamp is very high, and the light penetration is very strong and the life is long
Q:Want to do a LED street lighting, do not know how to start, please recommend books or websites, can understand the whole process of doing LED street lights!
You want to make street lights, that is easy and not easy, simple and simple, in fact, you want to see the manufacturer's demo assembly process on the Internet is impossible, because it relates to the confidentiality of the company. To see, you can go to the manufacturers to see, contact manufacturers business on it.
