- Q: What is the maximum power of a LED street lamp at present?
- If it is integrated, this power can be achieved.
- Q: What is the active power of LED street lamp? What is the relationship between input voltage and current and power?
- When the alternating current through the load resistor, and the resistance of the AC voltage and AC current through the resistor is the same phase, and between them the phase angle phi = 0 degrees, while the active power consumption in the resistive load, power grid to supply energy. When the alternating current through the pure inductance load, phase AC voltage on the advanced phase of current 90 degrees and the angle between them phi = 90 DEG, produce reactive power in inductive load, power supply of electric energy in the inductor for temporary storage and magnetic energy back to the grid into electricity such a periodic cycle, results for grid is not energy, so that the "reactive power", but "reactive power" and "reactive current" still exist. When alternating current through pure capacitance load, also similar to this, but the phase AC voltage on the lag phase of current 90 degrees and the angle between them phi = - 90 degrees.
- Q: How to calculate the number of Duodawa with LED lights
- First of all, if the width of the road is 20 meters wide, the road should be the main road, and the cloth lights will do.Assuming the double symmetrical cloth light, the lamp pole height is at least greater than the width of the road 1/2, so the pole height is 12-14 meters.Suppose the 14 meter pole, the street lamp installation spacing is generally about 3 times the height of the lamp post, so the distance is at least 40 meters.40 meters distance, height 14 meters, in this case, LED street lamp power to more than 200W power, can basically meet the main road lighting requirements.
- Q: What is the principle of constant current power supply in LED street lamps?
- Inductors, coils, transformers, these inductors are switching power components, one of the main characters,The role is to assume load or pressure, isolation, filtering and so on.All other components, resistors, capacitors, and protective elements are used.
- Q: How to select suitable driving power for LED street lamp
- A high pole lamp power, there are some low power courtyard street lamp, a power voltage, there are low, are prone areas in lightning, so the constant current drive, not only good performance, but also can be good heat dissipation, anti lightning, anti rain.
- Q: What is the role of heat phase change material on a LED street light?
- To help its heat dissipation, stabilize its effectiveness, and play its energy-saving features, the most important thing is to extend its service life, as we all know, LED street lamp technology is the biggest difficulty is the problem of heat dissipation.
- Q: Why solar energy centralized power supply street lamp must be supplied by AC LED lamp?
- 1: DC transmission distance is limited, the pressure drop is very high2: DC voltage - protection switch, controller parts and other technologies immature or cost slightly higher3: DC wiring voltage is not very high, but the street lamp power is not small, the current will be very high, the cable cost
- Q: What is the reason for the low power factor of LED street lamp?
- What you said is not too clear, the general LED is to drive the switching power supply, switching power supply method of improving power factor is to increase the power factor correction circuit, power factor correction circuit is more than 50W, can play a role. 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 0.95There is no power correction circuit for the driving power of the first paragraph
- Q: Why does fog cause fog when the LED street lamp is aging?
- Specializing in the production of outdoor lighting facilities and all kinds of street lamps, LED lights, is the production of outdoor lighting and sales of high-quality outdoor lighting, street lamps and engineering facilities of professional manufacturers. Main production: landscape lamp, lamp, road lights, garden lights, LED lights, solar lights, LED lights, lawn lamp, underground lamp, electrodeless lamp, lifting lamp, lighting engineering, and related accessories business.
- Q: Compared with LED street lights, what are the advantages of graphene street lamps?
- And if compared to ordinary sodium lamp, but also can save energy 70%. Thus, on the basis of the same amount of electricity, graphene street lighting will be higher, and this benefit can also benefit drivers traveling on the road. Almost all of the common LED lamp has a "black light", but the street surrounding light, but dark; and graphene Street due to changes in brightness and light, can avoid this effect of road crossing chiaroscuro "".
