Q:Is there a place where trees can hold LED solar street lamps?
The sun shines on the space of the photovoltaic panels
Q:What is the heat dissipation principle of a LED street lamp?
Mainly include: natural convection heat dissipation, fan cooling, heat pipes and loop heat pipes, heat dissipation, etc.. The fan is forced to heat, the system is complex, the reliability is low, and the heat pipe and the loop heat pipe have a high cost of heat dissipation.
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?
Generally have 20W, 30W, 50W, brightness can be replaced by 100W, 150W, 200W power high-pressure sodium lamp 30W~50W power is enough for a common trunk road.
Q:What's the advantage of Led street lights?
The first radiator and lamp shell integration design, LED is closely connected with the shell, the shell wing and the air convection heat, and fully guarantee the LED street lamp life of 50000 hours. According to the calculation of work 12 hours a day, its life expectancy is 10 years, very low maintenance costs; the lamp adopts Aluminum Alloy die-casting molding, can be effective in cooling and waterproof and dustproof. The surface of the lamp has been treated with UV resistance and corrosion resistance, and the overall lamp meets the IP65 standard;The use of monomer ellipse reflector design with ball arc surface, to control the LED light in the required range, improve the lighting using uniformity of light and light energy rate, better highlight LED lamp energy saving advantages. Compared with the traditional sodium lamp, the utility model can save electricity by more than 60%;
Q:Which is better, the LED street lamp and the traditional street lamp?
For street lighting and tunnel lighting projects, the sodium lamp itself has a large power, greater starting current, and thicker cables. Led because the power is small, the cable needs small, the overall cost of the project, consider the cable, then can be about 20% cheaper. The power can be saved by about 30%, and the service life is increased by 50%.
Q:What are the after-sales service of solar LED street lamps?
Check whether the current is good waterproof and lightning protection measures, whether the goods meet the delivery samples, construction lights, and related lamps and materials standards, to prevent the injection of defective products, reduce labor, and strive for a qualified acceptance. These are personal opinions, and the work may still need to be done. I am here for the time being, and leave it to other friends
Q:What is the role of heat phase change material on a LED street light?
Mainly to play the role of heat dissipation! I don't agree with that upstairs. The heat dissipation of LED street lamp can be solved by some auxiliary things. For example, a small fan with a stronger coefficient of heat is used as a shell...... And so on, these can solve the problem of heat dissipation!
Q:The power supply voltage of LED street lamp is the same, but the wattage is different. Can the power supply be general?
Although the output voltage is the same, but the 40W voltage with 50W lights do not work, 50W power to drive 40W lights, no problem.
Q:What is the difference between solar LED street lamp and ordinary energy-saving street lamp?
LED solar street lamps use solar photovoltaic cells to provide electricity, solar energy as a new green energy, "inexhaustible" and "endless"".
Q:What qualifications does LED street lamp product need? Do you need 3C certification?
3C certification is in fact the English name "China Compulsory Certification" (China Compulsory Product Certification System) in English abbreviation, but also the country's mandatory product certification of the use of a unified mark. As the national safety certification (CCEE), import safety license system (CCIB), China Electromagnetic Compatibility Certification (EMC) three with a "CCC" certification authority, and the State Administration of quality inspection China is a sign of advanced recognition standards and international supervision committee, has irreplaceable importance.
