Q:What are the components of a LED street lamp?

Street lamp pole, support arm, lamp (constant current power supply, light emitting system)

Q:How many watts is the LED street light 30W-900M?

The power is 30W, and the 900M is the current.

Q:How much is the LED street lamp?

Should not be cheap, power 200W or so, the main driver expensive

Q:How much is the LED street lamp and driving power 85W

Generally a dollar a W, warranty for three years.

Q:What's the main reason for LED street lights?

That is the power inside the solder

Q:What are the parts of a LED street lamp?

Solar energy is one of the most direct the most clean energy, solar energy is a huge amount of renewable energy, each day to reach the earth's surface radiation can be approximately equal to 2.5 millions of barrels of oil, can be said to be inexhaustible. The LED spectra of almost all concentrated in the visible light spectrum, so high luminous efficiency, is generally believed that energy-saving lamp energy-saving 4/5 is a great initiative, but also energy-saving energy-saving lamp LED than 1/4, this is a great reform of solid light source. Solar LED lighting integrates the advantages of solar energy and LED.

Q:Is the LED courtyard light a LED street light?

Secondly, the garden lamp grounding should be careful and serious, grounding wire should be set, along the courtyard lights into a network, and not less than 2, in order to ensure that short circuits, reduce accidents.After the circuit has been connected, it can be officially used for inspection and ensure safety. If the lamp doesn't work, you need to continue to check the circuit.This is the use of city power LED street lights, Zaozhuang Jetion photoelectric solar lamp, there are also suitable for scenic spots, residential areas, villas style, it does not need such a complex process

Q:How to choose the power of solar street lamp?

Advantages: simple installation, in the box after power according to the load size and the actual situation of the line tailored investment economy, energy saving ratio between 20-30%. 2 disadvantages: affected by the actual line voltage, the energy saving effect is not significant and unstable, if the line voltage environment is only 210, so energy-saving space is very small, and the end of the street may be in half on or off state. If the line voltage at the front end of the box is too high, the front part of the street lamp will be burned out. Thus, the harm to the light source will be great, and the maintenance cost will be high. In this process, due to the reduction of the voltage, the illumination will be correspondingly sacrificed". Comments: the above situation is the road Lantern Festival electric cabinet in the past two years in the process of street lighting energy-saving applications summed up the lessons learned. So far, this kind of energy saving law has been phased out. High power LED street lamp can achieve the purpose of high efficiency, energy saving, environmental protection, high color rendering and long life through a semiconductor light-emitting material.

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 is the reason for the low power factor of LED street lamp?

The LED street light power is generally more than 100W, if the power factor is low, it can only show that its driving power supply, there is no power factor correction, or is not done well.Well done, it should be more than 0.95.
