LED Street Light Solar Lighting CMAX-S5

Q:400W high pressure sodium lamp can replace 150WLED lamp? Luminous flux?: The life of LED street lights is much higher than that of high pressure sodium lamps, which are generally replaced by LEDLuminous flux comparison, it must be high sodium light, but the light efficiency of sodium lamp utilization is not high, many light is invalid, but also poor color rendering, LED generally do white light, see clearly, bright

Q:How is the glare of a LED street lamp solved?: You need to work on the LED drive to shorten the PWM cycle until you don't feel the glare when you're moving fast.

Q:What is the active power of LED street lamp? What is the relationship between input voltage and current and power?: Here, we define the phase angle advance as positive, and the phase angle lag as negative. The actual load is resistance, inductance, capacitance inductance capacitance of three types of complex, composite after referred to as "impedance", written in mathematical is: Z= R+j. where R is the resistance impedance, XL inductance, XC capacitance. If > 0, known as the "perceptual load"; conversely, if < 0 called capacitive load. Alternating current through the inductive load, the phase voltage of the alternating current phase advance; alternating current through the capacitive load, the lag phase alternating current AC voltage; electrical engineering definition of the power factor angle phi angle of power factor angle phi Cos phi is called the cosine value of power factor. For resistive load, the voltage and current of the phase difference of 0 degrees, therefore, the power factor of the circuit is 1 of the maximum; and pure inductance circuit, voltage and current phase difference of 90 degrees, and is a leading current voltage; in pure capacitance circuit, voltage and current phase difference is - 90 degrees. The current leading voltage. In the latter two circuits, the power factor is zero. For a general load circuit, the power factor is between 0 and 1. By mathematical impedance Z=, R+, J, if XL = XC, then Z= R, that is, impedance Z becomes a pure resistor, power factor is equal to 1.

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:What is the principle of constant current power supply in LED street lamps?: Constant current drive IC, which is the core component of constant current power supply, utilizes the principle of PWM (wave width control)The power of digital square wave, and then according to the information management of the power supply source from the partyThe duty ratio of the wave thus keeps the output current constant.Field effect transistor or module

Q:Solar street lamp, 60 watt LED lamp holder, with large battery: Total lighting time per night (temporarily indicated by H);60W the lamp cap is divided by the battery's rated voltage to draw the current (temporarily indicated by A)The number of days required for continuous wet days (temporarily indicated by T);Battery to prevent overcharge and over discharge, generally charged to 90%, discharge more than 20%, take 70% calculation, formula for:Battery capacity = 70% (A*H*T).

Q:What is the LED lamp light?: LED is English light emitting diode (light emitting diode) abbreviation, its basic structure is a electroluminescent semiconductor chip light emitting materials, with silver glue or glue curing to the bracket, connecting a chip and a circuit board and then with silver or gold, then sealed with epoxy resin around, to protect the internal core role finally, the installation shell, so the seismic performance of LED lamp is good.

Q:LED street lights installed on both sides of the road, horizontal installation and angle installation (0~30 degrees), natural convection heat dissipation, that good heat dissipation.: Generally speaking, this is a better angle installation, and the light source installed vertically below is the best,In fluid mechanics, the density of hot air is smaller than that of cold air, small density, light mass of hot air rises, cold air sinks, and natural convection occurs. But it doesn't have to be angled, depending on the shape of your fin design and the way it is cooled.

Q:How long does the general power LED power supply cycle last? Such as street lights, power supplies, 150W, 180W?: Now what research, generally 32 days can be delivered, I do the lamp,

Q:What is the reason that the range of the LED100W street lamp is not enough or the brightness is not enough?: LED street lamp with the conventional high-pressure sodium street lamp is different, the light source of high power LED lamp with low voltage DC power supply, by the synthesis of GaN based blue LED and yellow fluorescent powder, white LED, with high efficiency, safety, energy saving, environmental protection, long life, fast response, high color rendering index unique advantages, can be widely used in city road lighting.
