- Q:What are the parts of a LED street lamps?
- The working principle and design of solar street lamp LED 2008 01 Friday 25 March 22:28 with the world energy crisis intensifies, countries are seeking a solution to the energy crisis, a road is used for new and renewable sources of energy; the other one is looking for new energy-saving technologies, reduce energy consumption, improve the utilization efficiency energy.
- Q:Location of constant current source for LED street lamp
- Solar street lighting controller is divided into two buck and step-up, Buck 50 yuan, step-up 80 yuan, the warranty for three years. Now the conventional 6 meter 30W power solar energy set price is about 1260 yuan, the detailed price ha needs to calculate according to the lighting time and the rainy days.
- Q:How to identify LED street lamps do well or not?
- What is the light source efficiency of the luminaire, that is, the power factor, which is generally above 95%.
- Q:LED street lamps must be constant flow source? No constant current source, can I?
- Now generally constant current power supply, if not the constant current power supply has a great damage to the lamp
- Q:How is the rated current of the LED street lamp holder?
- The rated power of the lamp cap is divided by the input voltage and then divided by the power factor.
- Q:How to calculate the number of Duodawa with LED lights
- Road lighting requirements: mainly including illumination requirements, illumination uniformity requirements of two kinds.Uniformity is generally over 0.3, the greater the uniformity, indicating that the street lights, walking more open, lighting effect is better.Illumination is related to power and installation height of luminaire. For the street lamp, we hope that the greater the angle of light, the better evenness can be achieved, and that the distance between the lamp posts can be widened, the number of the lamp posts can be reduced, and the cost can be saved.
- Q:Why do street lights use bat wings to match the light curve?
- Make full use of light. LED light is diffuse type, not only will be the problem of uneven illumination glare.
- Q:How to distinguish whether the LED lamps glare seriously, whether there is a standard?
- Glare can be divided into disabling glare and non glare. Any glare that reduces the vision of the human eye is called disabling glareReduces visibility of visual objects, but does not necessarily produce discomfort; the glare that makes people feel unhappy is called "no"Comfort glare.
- Q:LED lamp with air leakage to help the thunder?
- No help.The leakage switch only appears on the circuit of the output end of the switch, the leakage current exceeds the set value automatically, and the utility model plays the role of protecting the output terminal.But the lightning stroke does not have the protective function to the leakage switch.
- Q:Does LED street lights save electricity?
- LED streetlights do save electricity.LED light is small: LED is basically a small chip, encapsulated in epoxy resin, so it is very small, very light.Low power consumption: LED power consumption is very low, in general, the working voltage of LED is 2-3.6V. The operating current is 0.02-0.03A. That is to say, it consumes no more than 0.1W.
