4.We can offer you a competitive price .Because you are our potential and valued customer .

5.We ,CNBM ,has our own factory :CNBM JETION SOLAR .We can also customize according to customers' need . You can google our factory .

Q: What is the price of the LED street lamp from 30W to 60W? What are the advantages of the LED street lamp?: Light emitting diodes (LightEmittingDiode, abbreviated as LED) is a semiconductor pn junction formed with weak electricity can light high efficiency solid-state light source based on the forward bias voltage and the injected current, injected into the P region of the hole and injected into the N region electron in diffusion into the active region after radiation and emit a photon, electric can be directly converted into light energy.

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: 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 is the design height and illuminance of LED street lamps?: The design height and illuminance of LED street lamp are based on the design standard of urban road lighting, and the national standard is CJJ45-2015.

Q: The width of the road is 20 meters, the distance of the street lamp is 25 meters, and the number of tiles is led. How much is the pole?. How to calculate?: Symmetrical lamp, rod 10 meters high25 illuminance, (10*1.414*2) *10*25/90=77WTherefore, it is recommended to install LED lamp 70~100W30 illumination, 100-120WThe above is based on quality chip light source calculation

Q: Do constant current LED power supply for street lamp power supply? Is it better to use LED constant voltage power supply?: General is constant current power, street light is not clear, but 90% are constant current power.

Q: Is there a place where trees can hold LED solar street lamps?: The sun shines on the space of the photovoltaic panels

Q: How big wires should fifteen LED street lights require?: Yes, you need to know what the power value is for each or 15 street lights

Q: What are the specifications of LED street lamps?: The integrated specifications go up from 30W to one specification per 10WSingle from 28 onwards, each 14W for one specificationModules from 30W onwards, each 30W for one specification

Q: What is the starting current of the LED street lamp for 220V and 30W?: Unlike an energy-saving lamp, LED needs to be started with a high voltage, but normally lit, of course, the lighting current will be slightly larger, mainly because the capacitor is usually used for filtering
