The display of the LED Lighting-28W
The applications of the LED Lighting-28W
- Q: How to identify LED street lamps do well or not?
- Overall, 1 lumens per watt lamp (what is the value of the lamp lumens not) are now generally more than 85LM.2, the light distribution curve of the lamp is how, now popular is bat wing light effect.
- 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: 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: What role does the light controller and driver play in the LED street light component?
- Constant current drive chip solves the problem of uncontrollable current before constant voltage drive. At present, the constant current chip can achieve constant current accuracy of about 1%, and has a simple peripheral control interface, which can flexibly set the required output current, so it is very popular. But these chips are much more expensive than constant chips, and peripheral circuits are complex. At the same time, because of the constant output current, the whole chip will discharge faster when the battery is used as power supply.
- Q: How big is the power of a LED street lamp?
- See the lamp height requirements, 4 meters, 10 watts, 20 watts is OK, solar energy radar induction street lamp is this power
- Q: Solar street lamp, 60 watt LED lamp holder, with large battery
- This is calculated according to the number of days of continuous illumination under the condition that there is no solar charge.
- Q: The design idea of LED intelligent energy-saving street lamp
- Sound control is not recommended...The timing control circuit can be added in the driving power source to adjust the current supply of the LED light source to realize intelligent dimming.The advantages of this approach are relatively easy to implement and low cost.
- Q: What happens if the LED street is ungrounded? Is it a big problem?
- If a lamp holder is expensive, it should be sold for ten thousand yuan. If it is not damaged by grounding, it will be more harm than good.
- Q: LED street lights are different from high pressure sodium lamps (both street lamps), as well as superior power consumption
- LED power saving, energy saving, high brightness, strong penetration of sodium lamp, but it is very expensive
- Q: Installation method of high-power LED street lamp
- 1. when installing LED high-power street lamp, it is intended to be fixed with guide sleeve.2. be sure not to install the LED high power street lamp in case of pin deformation.
