- Q: Is the street lamp good with LED or solar energy?
- The LED lamp is compared with the traditional kind of dim lamp is concerned, its high photoelectric conversion efficiency, as we are not the reason of incandescent lamp, because it is the most power is transformed into heat, and then converted into light energy, is a waste of energy. The new LED lights will directly convert electricity to light energy, which is also more energy saving.
- Q: How to calculate the number of Duodawa with LED lights
- It's time to test the street lights of 200W. Because different manufacturers of street lamps, the use of LED road lamp holder is not the same, with light lens is not the same, resulting in the same big power of the total luminous flux is not the same, then the results will make the pavement illumination is not the same.To sea lighting 200W, a single luminous flux of more than 114, the installation of 14 meters height, spacing 40 meters, the average illuminance can reach more than 15LUX, the uniformity of more than 0.7.These indicators can not reach the main road lighting standards, can only meet the lighting requirements of secondary roads. To achieve the main road lighting standards, then almost need to use 240W or so.
- Q: How is the glare of a LED street lamp solved?
- 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.
- Q: How many lights can a high-power LED lamp be at least W?
- High power LED street lamp, as the name suggests, is a single power greater than 1 watts, using a new type of LED semiconductor light street lamps. At present, the standard of LED street lamps is generally the average illuminance of (uniformity of road surfaceilluminance), which is greater than 0.42 of the national standard. The spot ratio is 1:2, which conforms to the illumination of the road. The actual 1/2 center spot reaches 25LUX, and the 1/4 center light intensity reaches 15LUX, the minimum light intensity is 4LUX at 16 meters, and the overlap light intensity is about 6LUX.
- Q: The design idea of LED intelligent energy-saving street lamp
- Smart streetlights, I conceived. But it's out of the industry now.
- Q: What is the LED Street pressure balancing respirator?
- LED lamp pressure balancing apparatus is also called micro PU waterproof breathable valve at home, LED street is a wide application of pressure balance apparatus, such as: LED outdoor lighting, communication equipment, solar photovoltaic, auto controller etc..The role of the LED Street pressure balancing respirator is as follows:1, waterproof, dustproof, anti pollution, protection level IP65~IP68.2, chemical resistance, high and low temperature, anti-aging and so on, improve the harsh environment of the product reliability.3, prevent condensation, fog, and improve product life.4 、 micro heat dissipation and balance pressure difference. Improve product integrity.
- Q: Constraints on LED street lights
- The development of the domestic LED light source relative to foreign technology started late, from the international leading industry there is a certain distance, although the domestic LED light source theory of life can reach 100 thousand hours, but because of the heat problem cannot be solved completely and effectively, so that the actual life of large discount; unstable power supply system: LED driver power supply is the industry consensus in fact it is not stable, on the LED lighting industry back, because the driving power supply is an important part of the LED street lamp, which will lead to failure of the whole lamp fault. Due to poor reliability of power installed street lights are likely in a short period of time will be bad, the LED street lamp this outdoor height device, difficult installation, maintenance more difficult, for the lamp manufacturers, power supply instability makes the rising cost of maintenance.
- Q: What is the LED lamp light?
- LED (Light, Emitting, Diode) light emitting diode is a solid-state semiconductor device that converts electrical energy into visible light. It can directly convert electricity into light. The heart of LED is a semiconductor wafer, one end of which is attached to a bracket, one end is negative, and the other is connected to the positive electrode of the power to encapsulate the entire wafer with epoxy resin.
- Q: What is the voltage of the street lamp?
- The normal voltage of the street lights is also 220V, and his risk is the same as that of other common lighting points. But now some street lighting voltage may be slightly higher.
- 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.
