As an energy-saving and environmentally friendly lighting device, the China all-in-one street light has been widely used in urban and rural road lighting. So, how to judge the quality of a China all-in-one street light? Here are some practical methods.
High-quality light poles are usually made of hot-dip galvanized steel pipes, which have excellent corrosion resistance and can be used for a long time in harsh outdoor environments without rusting. The hot-dip galvanizing process ensures that the zinc layer is evenly attached to the surface of the steel pipe, and even at the cut of the pole, a clear coating can be seen. Generally, the service life of a hot-dip galvanized light pole can exceed 20 years. In contrast, cold-dip galvanized poles have a coating only on the surface, with no coating at the cut, and their lifespan is usually only about 1 year, making them prone to rust and corrosion.
The design of the light pole should be reasonable, able to withstand certain wind forces and other external forces. Generally, the wall thickness of the pole should be sufficient, and the dimensions of the upper and lower diameters should match the height and lighting requirements of the street light. For example, a 6-meter-high pole with an upper diameter of 60mm, a lower diameter of 143mm, and a wall thickness of about 2.75mm has good structural strength, ensuring the stability of the street light during use.
The conversion efficiency of the solar panel is one of the important indicators to measure its performance. The higher the conversion efficiency, the more electricity can be generated under the same light conditions, and the longer the lighting time of the street light. Generally, the conversion efficiency of monocrystalline silicon solar panels is higher than that of polycrystalline silicon panels. Therefore, monocrystalline silicon panels can be prioritized when selecting.
The power of the solar panel should match the lighting needs of the street light and the capacity of the battery. If the power is too low, it may not meet the lighting requirements; if the power is too high, it will increase costs. At the same time, the size of the panel should be moderate, ensuring sufficient sunlight absorption without being too bulky, which would affect the aesthetics and installation of the street light.
Currently, the commonly used batteries for solar street lights are gel batteries and lithium batteries. Gel batteries are relatively cheaper and have larger capacities, but their discharge depth is limited. Lithium batteries have a high discharge depth and a long service life, but they are more expensive. When choosing, the type and capacity of the battery should be determined based on the usage needs and budget of the street light. For example, if the street light needs to provide long lighting during cloudy or rainy days, a battery with a larger capacity should be selected.
The quality of the battery directly affects the service life and performance of the street light. Choosing batteries from well-known brands ensures quality and after-sales service. Some small-brand batteries may have unstable quality and short lifespans, which could cause inconvenience in the use of the street light.
The brightness of the LED lamp is one of the key factors affecting the lighting effect of the China all-in-one street light. When selecting, choose a lamp with appropriate brightness based on the installation height and lighting range of the street light. At the same time, pay attention to the light decay of the lamp. High-quality LED lamps have minimal light decay and can maintain high brightness even after long-term use, while low-quality lamps may experience severe light decay, resulting in significantly reduced brightness after a period of use.
Good heat dissipation performance can extend the service life of LED lamps. When selecting a lamp, check the heat dissipation structure and materials. For example, lamps using aluminum substrates, heat sinks, and other heat dissipation methods have better heat dissipation effects, ensuring that the lamp will not be damaged due to overheating during long-term operation.
