Q: What is the distance between the usual street lights?: There is no standard, and some are required to achieve the value of illumination, there is no hard and fast requirements, generally speaking, the distance between the street lamp and the lamp height and the number of watts.

Q: Do you think it is expensive to install LED street lamp with WIFI function?: The cost will be much higher, and it will involve control and network problems.

Q: LED street lights around 2800K, the highest color temperature, how many lumens per watt?: The light loss of the lens and the mask two is about 10%, and the light effect of LED is only 117LM/W, and the power loss is even lower. All of the lights need to be achieved 120lm/W, basically impossible to achieve.

Q: Which is better, the LED street lamp and the traditional street lamp?: LED well, because it's energy efficient and bad, it doesn't affect anything else

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: What is the luminous flux of LED30W solar street lamps?: The luminous flux of LED light source is 1W 45mil 110lm to 130lm (this is a test at the rated 25 degrees at room temperature, in the actual application is certainly not to), regular 30wled products are a lens two with a light, even the best lens in there will be the loss of good, good quality of the lens, the loss in 10%, ordinary loss in more than 30, LED street common 30W are the traditional lamp type, the lamp outside and glass lens, the light loss is higher, so the comprehensive down than ordinary street lamp has a conventional calculation method is practical the luminous flux per lamp w lumens 0.7 is multiplied by the number of lamps, the luminous flux *0.6, luminous flux *0.75 good quality, this is probably the calculation method.

Q: How to maintain the LED street lamp?: LED is best used within 3 months of its original packing condition to prevent the stent from rusting. When the LED bag is opened, it should be used as soon as possible. At this time the storage temperature is 5 degrees -30 degrees centigrade and the relative humidity is below 60%.

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: The 6 meter high watt LED bulb lamp should match: Generally equipped with 30W led, Yangzhou is the country's largest production base of street lights, manufacturers can visit to see.

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.: The angle of heat dissipation is good, because the general hot air will spread upward, and the slope is more convenient for the diffusion of hot gas.
