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:Will the wisdom of street lamps be the future of development? At present, which is more reliable?
At present, China vigorously promote the construction of smart city, so the wisdom of street lighting is also the future trend of development, will replace the traditional street lamps. At present, the wisdom of street lighting manufacturers are many, a representative can Baidu, "Shanghai as if through" the company's wisdom, streetlights have been successfully piloted.
Q:Street lights and signal circuit connections
LED street light color light than many high-pressure sodium lamp, high-pressure sodium lamp color index is only 23 enterprise directory, while the LED lamp more than 75 of the color index, take into account the psychological point seems to be visually reachedThe same brightness, lighting LED lamp, can be reduced by an average of 20% or more, than high pressure sodium (refer to inluReasonable lighting standard); page 5, LED street light a small decline, a year decline was less than 3%. 10 years still reached the road soHotel and illuminance requirements, while the high pressure sodium lamp big drop, about a year has dropped by more than 30%, so, LEDStreet use power can be lower than that of high-pressure sodium lamp designs; page 6, LED streetlights energy-saving automatic control devices can be achieved in time to meet the situationLighting conditions, as far as possible to reduce the requirement of different maximum power saving energy; Guangyuan Wang Technology Co. Ltd.
Q:Features of LED street lamps
LED street lamp is different from conventional, LED light source adopts low voltage DC power supply, by the high white GaN based blue LED and yellow synthesis, has the advantages of high efficiency, safety, energy saving, environmental protection, long life, fast response, high color rendering index unique advantages, can be widely used in the road. Cover can be made, high temperature up to 135 degrees, low temperature resistance up to -45 degrees. 1, the characteristics of its own - one-way light, without the proliferation of light, to ensure the efficiency of light.
Q:Does the LED street lamp work well with a single light source or with integrated light sources?
You look at the voltage LED power supply, generally 12V, white light, you can string 4
Q:LED lamp of common sense, several, such as the LED street lamp, there are many W have many stars, some lamp is a lamp there are a lot of W number
Are you saying that a lamp with LED lamp or with a large number of W! This is not to say the street is not very high if you don't need very bright I think might use 1W 3W this kind of W is relatively smaller number of beads will power many dozens of W a integrated product although the flux is large but his heat is very large if you can not solve it scattered don't consider those.... But if your technology is mature and fairly good, you can use it to integrate power
Q:Can you tell me how to solve the problem of LED street lamp heat dissipation? Ask for an introduction
LED lighting is recognized as the next lighting technology due to its electricity saving, environmental protection and long life. LED, however, has 70% of the electrical energy that is converted into heat and must be cooled. Although the LED luminescence technology has been rapid development, has reached 200lm per watt light reported, but the LED heat is a very difficult problem in LED lighting, LED lighting development became a stumbling block on the road.
Q:What is the principle of constant current power supply in LED street lamps?
The source of power source rectifier lamp mainly alternating current, and the electronic components are basically.Made in direct current. So the input power must be rectified first.Diode zener diodes and Schottky diodes are common in power management systems.Many small power components operate at low voltages or require reference electricity in the systemVoltage will use a zener diode; in the switching power supply, the final low voltage DC output
Q:LED technical requirement of street lamp 100W
(5) the environmental temperature of LED street lamp should be -20 to +50 centigrade, and other special requirements such as temperature, humidity and corrosiveness of the local environment should be satisfied.(6) the power factor is greater than or equal to LED 0.95 lamps, lamp power supply efficiency is more than 95%.(7) the working voltage range of LED street lamp is from 85V to 265V (in this voltage range, LED lamps can still work normally).(8) LED street lamp has surge suppression performance (against lightning stroke), the input over-voltage protection, when the voltage is restored to normal, can resume work.
Q:Who knows the relationship between the number and weight of LED street lamp
In fact, there is no relationship at all. The weight of the street lamp: a large part of the relationship between the shell and the heat sink inside it.
