- Q: How many kinds of power do LED street lights have? How much brightness can it replace the high pressure sodium lamp? What kind of power does the general main road need?
- There are 60, 90120150200 of the main road should use 90 to 150, 8 to 12 meters of installation height, I do Dialux lighting simulation design is common, yes
- Q: What are the components of a solar street lamp?
- Solar panels used to transform solar energy into electrical energy; solar controller: used to charge and discharge the battery, also the battery charge, over discharge protection and timing switch for LED lamps; battery: electrical energy use for storing solar panels; LED lights: used for lighting in the night thank you!
- Q: Does LED street lights save electricity?
- The white LED: in 1998, light white LED is only 5 LM / W, in 1999 has reached 15 LM / W, this index is similar to general household incandescent lamps, and in 2000, light efficiency of white LED has reached 25 LM / W, the index and the tungsten halogen lamp is similar. In 2005, the light efficiency of LED was up to 50 lumens / watt. In 2010, the light efficiency of LED reached more than 100 lumens / watt. The working current of white light LED can reach ampere level. Thus, the development of white LED writers using lighting sources, will become possible reality.
- 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: How high should the installation height of the LED street lamp be?
- In order to avoid glare, you can choose the f (d) (E), the installation height of street lights should not be less than 4.5m. The distance between the poles of the street lamp can be 25 to 30m, and the distance between the lamp posts entering the curve should be reduced appropriately.
- Q: LED street lights generally use how many W, how much density is more appropriate?
- 100W or so, the distance is about the same as ordinary street lights!
- Q: Constraints on LED street lights
- Maintenance problem. High pressure sodium lamp is good for maintenance. As long as the lamp is scrubbed, it is not necessary to replace it. The light source is changed once every 4 years, which is very convenient. And LED street lamps, involving LED tubes, modules (including lenses, etc.), power devices, etc., components and components of the possibility of greater damage, maintenance difficulties, it is possible to replace the whole, higher costs. High price: LED street price is 2-5 times that of high pressure sodium lamp, even if the power consumption of LED lamp is only 1/2 HPS, but because the price is much higher than that of high pressure sodium lamp, high pressure sodium lamp is replaced by LED cost recovery cycle will still be very long;
- Q: What is the difference between solar LED street lamp and ordinary energy-saving street lamp?
- Making full use of solar energy resources has positive significance for alleviating the tension of conventional energy sources. LED and solar lighting installation is simple and convenient, do not need the laying of cables and other large foundation engineering like ordinary street, just need to have a fixed base line, and all the control sections are placed in the lamp holder, to form a whole.
- Q: What are the ways to save energy in street lamps?
- Midnight lights: as the name suggests, in the evening when the amount of half the amount of light, only half of lighting to meet the requirements. As the voltage is proportional to the change with the load, after entering the middle of the night when the load is reduced, the voltage higher than when lights before midnight light, and at this time on the road, pedestrians and vehicles to reduce, put half the street lamp can meet the lighting requirements. The night lights have a variety of luminaire-distribution-style, many of the commonly used vibration rod.
- Q: Who knows LED street lamp warm white light and positive white light have what difference, how should choose?
- If the power is the same, the brightness of the white and warm white light should be the same.
