What issues should be paid attention to when purchasing street lamps?
Nowadays, solar street lamps are widely used, but now the market price of solar street lamps is different, and the quality of solar street lamp manufacturers varies. It is inevitable that some manufacturers will blow up their products. In fact, the quality of the products has a major negative impact. So what issues should be paid attention to when buying? Let the professional manufacturers teach you:
1. Counterfeit chips, low-end chips
The core of LED lamps is the chip, which directly determines the performance of the lamp! However, some unscrupulous manufacturers take advantage of customers' unprofessionalism and use low-cost chips from the perspective of cost, which causes customers to buy low-quality products at a high unit price, causing direct economic losses and causing serious quality risks to LED lamps.
2. Configure virtual labels and exaggerate configuration parameters
The popularity of solar street lights is also accompanied by a reduction in price and profit. Customers have repeatedly compared prices and demanded low prices. The fierce competition has also caused many solar street light manufacturers to cut corners and imaginary product parameters. There are problems in the wattage of the light source, the wattage of the solar panel, the capacity of the battery, and even the materials used for the solar street light pole.
3. Poor heat dissipation design and unreasonable configuration
In terms of heat dissipation design, every time the PN junction temperature of the LED chip increases by 10 degrees, the life of the semiconductor device will be reduced by multiples. Due to the high brightness requirements of LED solar street lights, the use environment is relatively harsh, if the heat dissipation is not solved well, it will quickly cause LED aging and decrease stability. In addition, unreasonable configuration often leads to specific usage conditions that fall short of expectations.
4. The copper wire pretends to be a gold wire and the controller problem
Many LED manufacturers try to develop materials such as copper alloys, gold-clad silver alloy wires, and silver alloy wires to replace expensive gold wires. Although these alternatives are superior to gold wires in some properties, they are much worse in terms of chemical stability. For example, silver wires and gold-coated silver alloy wires are susceptible to sulfur/chlorine/bromination corrosion, and copper wires are prone to oxidation and sulfidation. For the encapsulated silica gel similar to the water-absorbent and breathable sponge, these alternatives make the bonding wire more susceptible to chemical corrosion, the reliability of the light source is reduced, and the use time is long, and the LED lamp beads are more likely to break and die. As for the solar street lamp controller, if the controller is faulty, during the test and inspection process, "the whole lamp is off", "the lamp is not switched on time", "partially damaged", and "individual LED lamp bead is dead" will appear during the test and inspection process. , The phenomenon of "the whole lamp flickers and false bright".
