Quality of solar street lights - how to identify the quality of solar street lights

Quality of Solar Street Light - system composition
Solar cell components generally use monocrystalline silicon or polycrystalline silicon solar cell components; LED light holders generally use high-power LED light sources; The advanced controller also has the function of adjusting the lighting time in four seasons, half-power function, intelligent charging and discharging function, etc.; the battery is usually placed underground or there will be a special battery insulation box, which can use valve-regulated lead-acid batteries, colloidal batteries, Iron-aluminum batteries or lithium batteries, etc. Solar Lights work fully automatically without trenching and wiring, but the light pole needs to be installed on the embedded parts (concrete base).

Look at the lamp shell: the upper and lower parts of the high-quality lamp shell are closely connected, and the gaps are even in size. The color of the lamp shell is pure, and the finish without variegation is better. The shell is more textured, and the whole lamp feels heavy in the hand. However, inferior lamps and lanterns are not tightly connected, have misalignment, and the spray color also has penetration. The lamps are not made of solid materials, and the shell is sunken when pressed with fingers.

Look at the heat dissipation performance: Although the heat of solar street lights is not as intense as that of traditional sodium lamps when they are working, the heat is not small. Therefore, good heat dissipation is necessary, which will affect the life of the light source. Regarding heat dissipation, we can use a thermometer or hands to directly sense and compare. The same power, the same working time, the lower the temperature, the better.

Look at the lead wires: Although the lead wires account for a very low proportion of the entire lamp cost, we can find the difference between regular manufacturers and small workshops from this small place. Responsible manufacturers will use high-quality copper core wires of appropriate thickness as lead wires, while some manufacturers cut corners and materials in order to save costs, replacing copper core wires with aluminum core wires, and even discounting the thickness of lead wires. This seriously affects the electrical conductivity, thereby adversely affecting the performance of the light.

Look at the lens: a high-quality lens not only has a good light distribution effect, but also has excellent light transmission performance. A good lens looks more pure and glossy.

Look at the bolts: Although ordinary users cannot use professional tools and techniques to judge professional issues such as the luminous efficiency of lamps. But by observing such as the supporting bolts of the lamps, we can know from the side whether the lamps and lanterns manufacturers are responsible. Whether you are making products with your heart. Good lamp bolts must be in full compliance with the standards, and the best ones are made of stainless steel, followed by galvanized bolts. And the internal wire teeth and bolts of the lamp fit perfectly, and there will be no looseness
