Q:How many watts is the LED street light 30W-900M?
30W is the W number of street lights. 900M, is the current power supply, 30W lamp 900 Ma, more heart lighting to help you
Q:Can the power supply for the LED street lamp be placed under the lamppost?
In fact, it is more convenient to put the driver into the electric door directly. If the later stage needs maintenance, it is not necessary to remove the whole lamp.
Q:Excuse me, LED experts. How many watts do LED street lights usually have on the roads?
The most common sodium lamps for street lamps are 100W, 150W, 250W, 400W
Q:What is the reason that the longer the wire pulls on the LED street lamp, the lower the voltage?
Resistance will block the passage of electricity; the greater the resistance, the greater the loss of electrical energy in the line.
Q:Does the LED street lamp need a starter?
LED light is not a starter, is a constant current source module, is 220V city power rectifier, with constant current circuit to each LED lamp power supply; LED lights can be connected in series, and then parallel. There is also not constant current, but in each series of branch current limiting resistors, to consider the range of voltage fluctuations, select the current resistance resistance value and power.
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:LED street light dedicated drive power 98W14 string 7, and ask 14 string 7, and what does that mean?
14 strings of beads strung up voltage at around 48, indicating that the LED lamp is 48V system, LED lamp voltage is common for 12V, 24V and 48V are increased in order to reduce the current voltage is such a high efficiency lamp, 7 and 14 series and beads such power is 98W and you can have 14 strings of 10 and then the lamp is 140W street lamp, street lamp is 14 If you design on the design so in the production of aluminum substrate is designed to be 14 on the aluminum plate (the aluminum substrate is a circuit board, the welding beads in the above).Generally common street lamps recommend using 24V system (less than 40W suggested using 12V), because the voltage is relatively low, so relatively safe, but also the most street accessories, easy to buy.
Q:Can you tell me how to solve the problem of LED street lamp heat dissipation? Ask for an introduction
(because you don't have to worry about heating up, you can use a relatively inexpensive LED wick). Road lighting is a long time, wide range, and is preferred for LED lighting applications. But the outdoor road, wind and rain, a world of ice and snow, harsh environment, that is to say, LED lighting preferred one of the most difficult to fix the object, makes the most of the current LED lamp company lost a lot of money, feeling little hope in front of.
Q:What is the actual service life of the LED street lamp?
In good heat dissipation, rated current work, with constant flow drive, high quality LED life up to 50 thousand small season
Q:How to judge the light type of LED street lamp?
Either for the manufacturer to provide, or to do their own spectral analysis, the naked eye is not visible
