How to choose municipal street lamps? Don't just look at the wattage! Expert 4 standards to avoid 90% of engineering pitfalls
Many friends who do road engineering, municipal procurement, and park infrastructure choose LED street lamps and always fall into pitfalls: the lamp shell rusts within a year, the lens emits serious yellow light decay, and maintenance takes half a day. The maintenance cost is directly doubled in the later stage.
The price of street lamps on the market varies greatly, from one or two hundred to thousands of yuan, and simply comparing power and taking low-cost goods will ultimately hurt oneself. Today, combined with the product design of shenzhen kingconn Technology Co., Ltd, I will give you a set of practical street lamp selection tips that can be implemented, suitable for main roads, branch roads, and park roads.
1. Look at the lens: Refuse PC lenses, prioritize matrix-type glass lens modules. The lens of the street lamp is the core component that wears out the fastest, and it is also the key point to open up the gap in product life. Most of the low-priced street lamps on the market use PC plastic lenses. After being exposed to wind and sun for half a year in the open air, they turn yellow and become hazy, resulting in a significant decrease in light transmittance and a decrease in road illumination. In saline-alkali areas, high-temperature southern cities, and coastal construction sites, plastic lenses will show module damage after 1-2 years.
The advantages of the matrix tempered glass lens module are obvious: it will not age or yellow permanently, and it is not afraid of high temperature exposure, rain, snow, frost, and so on. The light transmittance is as high as 95%, and the light transmittance performance is stable; It is corrosion-resistant and salt-and-alkali-resistant, suitable for coastal, mining, and high-temperature outdoor scenes; The surface is smooth and does not accumulate dust, it is automatically cleaned by rainwater, and it does not need to be manually wiped for a long time; Professional patent optics, wide-angle uniform illumination, no dark areas, no glare.
2. Look at the lamp body shell: die-casting aluminum, one-piece molding, avoiding the use of thin iron shell, which determines the waterproof, anti-impact, and service life of the street lamp. Many low-cost products use thin iron shell, which is easy to rust and water in long-term rain erosion, and the infiltration of the cavity will cause short circuit and burn the power supply.
Choose the overall ADC12 die-casting aluminum shell: one-piece die-casting, IP66 high protection, dust-proof and waterproof; ADC12 aluminum alloy has high mechanical strength, is resistant to strong wind and stone impact, and is not easily damaged during road construction; Thickened heat dissipation chamber, module heat is quickly discharged, extending the life of the LED and power supply. The Huiguang series adopts an integrated die-casting process throughout, which not only has higher mechanical strength but also has a more beautiful appearance compared to the split-pieced version.
3. Choose lamps based on light efficiency: Wattage is not always better the higher it is. It is important to recognize light efficiency. Wattage only represents the power consumption of the lamp and does not represent brightness. With the same power, low-quality lighting has a large loss and high heat generation, and most of the electrical energy is wasted as heat; High-efficiency lamps can convert more electrical energy into visible light.Here's an intuitive comparison: ordinary low-quality street lamp: luminous efficiency 80lm/w, 100W total brightness = 800lm; high-efficiency module projector: luminous efficiency 180lm / w, only 50W total brightness =9000lm; the latter is half the power, but the brightness is higher, and the electricity bill is directly cut in half. Only paying attention to the wattage and choosing high-wattage street lamps not only fails to meet the initial illumination requirements and cannot pass the municipal inspection, but also results in a large amount of electricity bills in the later period.
4. Look at the later maintenance structure: snap-open design saves a lot of labor costs. The street lamps are installed on both sides of the road. The more complicated the maintenance and disassembly, the higher the labor costs for high-altitude work. Traditional street lamps are completely sealed with screws, and repairing the power supply and replacing the module requires a complete set of tools, and disassembly and reassembly take at least half an hour.
5. Finally, summarize 4 tips to avoid pitfalls in procurement: choose glass lenses over plastic lenses, and eliminate PC lenses for coastal high-temperature construction sites; The shell is made of one-piece die-cast aluminum, and the thin iron plate assembly model can be used for a short period of time, but it must be reworked in the long run; Choose the right light according to your needs, not just the wattage, it's important to understand the light efficiency; Maintenance is convenient and reduces the cost of maintenance in the future.
Engineering procurement and road renovation do not need to blindly compare prices. The four points of lens, shell, light distribution, and maintenance structure should be used as strict procurement standards to select durable, low maintenance, and cost-effective long-lasting street lamps. Guangdong Kaiming Lighting Huiguang series LED street lamps, full set of engineering-grade configuration, suitable for domestic municipal roads and overseas road infrastructure projects, one-stop solution for road lighting pain points. Have you encountered the problem of yellowing of street lamp lenses and water entering the lamp shell when you do road engineering? Let's talk about the pitfalls we've encountered in the comments section! You can leave a message if you need to purchase street lamps or have a road lighting plan.
