What problems should be paid attention to when purchasing street lamps? solar street light-litersolar production plant

Nowadays, solar street light is widely used, but the market price of solar street light is different now, and the quality of solar street light manufacturers varies. It is inevitable that some manufacturers will blow their own products into hype, but in fact the quality of the products has brought a major negative impact. So what should you pay attention to when buying? Let professional manufacturers teach you: 1. Counterfeit chips, low-end chips LED solar street light The core of the LED solar street light is the chip, which directly determines the performance of the lamp! However, some unprofessional manufacturers take advantage of customers' unprofessionalism and use low-cost chips from the perspective of cost, so that customers can buy low-quality products at high unit prices, causing direct economic losses and serious quality problems for LED solar street light equipment. 2. The popularity of configuring false standard and exaggerating configuration parameters of solar street light is also accompanied by a decrease in price and profit. Customers repeatedly compare prices and ask for lower prices. The fierce competition has also led many solar street light manufacturers to cut corners and falsely standardize product parameters. There are problems with the wattage of light sources, the wattage of solar panels, battery capacity, and even the materials used for solar street light poles. 3. Poor heat dissipation design and unreasonable configuration In terms of heat dissipation design, for every 10 degrees increase in the PN junction temperature of the LED chip, the life of the semiconductor device will decrease exponentially. Due to the high brightness requirements of LEDsolar street light and the harsh operating environment, if the heat dissipation solution is not good, it will quickly lead to the aging of the LED and reduce the stability. In addition, unreasonable configuration often leads to the specific usage not meeting the expected value. 4. Copper wire pretending to be gold wire and controller problems Many LED manufacturers try to develop copper alloy, gold-clad silver alloy wire, and silver alloy wire to replace expensive gold wire. While these alternatives are superior to gold wire in some properties, they are much less chemically stable, such as silver wire and gold-clad silver alloy wire susceptible to sulfur/chlorine/bromide corrosion, and copper wire susceptible to oxidative sulfidation. For encapsulated silicones similar to water-absorbing and breathable sponges, these alternatives make the bonding wires more susceptible to chemical corrosion, the reliability of the light source is reduced, and the LED solar street light beads are more likely to break and die over time. As for the solar street light controller, if the controller is faulty, during the test and inspection process, there will be 'the whole light is offThe phenomenon of 'dead light' and 'whole light flickering and false light'.
solar lights is an inevitable and critical part of being a manufacturer, and it's more complicated than just manufacturing products and serving customers.
